If you use standalone machines and have lots of customers and many types of linen to be washed, you can choose powder products and add by hand to allow you the flexibly change the variety and amount but selecting an auto-dosing system from a good chemical supplier would be a better way to control chemical use and achieve a consistent wash quality.

If you use a tunnel washer or integrated washing system, a fully automatic liquid washing system should always be selected.

If your washing volume is low then its ok to choose a powder product but of course, it is also possible to use a liquid product. 

If the daily washing amount and number of machines / staff are higher then it is recommended to use a fully automatic liquid washing system

If you have complicated linen types and varying levels of staining / discoluration then it is advisable to contact a chemical supplier who will assist with your programming and auto-dosing, to give you the best consistent washes. 

Washing cost is always important but from experience, whilst choosing a cheap detergent and manually dosing may appear to be the best option but in reality it could cost you more in the long run.  Always consider re-washing, linen colour deteriation, staff costs, rejects and returns etc...

Yellowing of towelling after drying is usually caused by either over drying which also results in roughness to the touch and a shortened product life, or residual chemical being burnt in to the towels.

To prevent over drying, ensure that the dryer is set to heat up gradually, dry to a level which leaves a small amount of residual moisture (around 5%) and then cool down before the product is emptied.   Machines with moisture control settings are available and can help with this.   

Excess chemical can appear as burns, but when re-washed it comes out.   If this keeps happening to you then you need to speak to your chemical supplier, lower chemical usage or increase rinsing and water levels.

The term G Force relates directly to the amount of water extracted during the spin process. It is not directly related to "spin speed".  It has more to do with the "Diameter" of the wash drum.

If you look at the illustration below, it will help you to understand this. If you picture the blue dot

as a point on a small diameter drum and the purple dot as a point in a larger diameter drum, if it is

turned one revolution, the purple dot travels a longer distance. This means it achieves a higher speed in effect, thus "extracting" more water from a load.

This force is what is known as G Force and results in the highest amount of water being extracted from your load. The benefit for your business is less time in the dryer resulting in Labour and Energy savings.

Hard Mount Washers (also known as rigid mount) have no internal suspension and need to be securely bolted to a reinforced concrete floor. In general, they cost considerably less than soft mount washers. Due to the fact that they have a lower extraction or G Force (100-200 G), laundry will take a longer time to dry, than with a high speed machine.

Soft Mount Washers (also known as High Speed) have an internal suspension that cushions the vibration of high spin speeds. Due to the higher spin speeds, these washers achieve much higher extraction (320 - 420G Force) than hard mount washers. The nett result is a considerable saving in drying time and energy consumption, both contributing to higher profitability or production output.

There is a clear difference between Light Commercial and Commercial Washers and Dryers.

Commercial machines have an extremely robust construction, built to withstand continuous work, over a single shift or longer. They are normally sold in capacities upwards of 13kg, a size very poular with Laundromats and Motels.

Light Commercial machines do not have the same framework/chassis bearings and motors, that Commercial models do, and are therefore a lot cheaper. They are however, built to do more work than domestic machines, and are meant to do a number of loads per day, provided they are not overloaded and treated like a Commercial machine. If maintained correctly, and treated with due respect, they last much longer than domestic models.

1, to avoid uneven ground.

If the industrial washing machine is in the process of washing, the ground is unstable, and it is easy to cause the machine to vibrate too much, resulting in damage to the internal parts of the machine. This not only seriously affects the service life of the washing machine, but also is prone to unnecessary malfunctions.

2. Avoid wet and dark environments.

In the laundry room, if it is too humid and dark, it can easily lead to the corrosion of the internal parts of the industrial washing machine. At the same time, it is easy to produce bacteria and affect the washing effect of the washing machine; a good laundry room should have suitable temperature, dryness and sanitation. And ventilation is smooth.

3. Avoid excessive water temperature.

Under normal circumstances, when using the washing machine, you must add cold water before adding hot water. Otherwise, the parts of the washing machine are easily burnt or damaged. It is recommended that when washing clothes, it is best to ensure that the water temperature is around 5 to 40 degrees, which not only guarantees the quality of the laundry, but also does not damage the industrial washing machine.

4. Avoid sudden stops.

Industrial washing machines should not stop suddenly during operation, which would damage the running motor of the industrial washing machine.

5. Avoid both keys at the same time.

When washing clothes, it is forbidden to press two buttons at the same time, which may cause the circuit of the washing machine to malfunction, causing malfunction and affecting laundry washing.

6, Avoid using a non-breathable cover on the washing machine.

After washing the clothes, avoid using an airtight plastic film cover on the industrial washing machine. Similarly, you can't put the washing machine in a place where the temperature is too high or too low, and you can't put it in the sun.

The use of washing equipment in our daily life is very common, it can bring a lot of benefits to everyone, and it is also loved by users when using washing equipment. However, only qualified washing equipment can truly realize its value and satisfy users. So what are the requirements for a qualified washing machine?

Washing equipment should have the function of sterilization and disinfection. Hotel and hotel have large passenger flow and strong liquidity. As a public place, the health and safety of hotels and hotels is very important. To sterilize sheets, quilt covers, towels, bath towels and public goods, the hotel has strict washing equipment to have sterilization effect.

Hotel and hotel have large passenger flow and strong mobility. As a public place, the health and safety of hotels and hotels is very important. The bed linen, quilt cover, towels, bath towels and public goods are sterilized. The hotel has strict hygiene requirements. In order to enhance the washing effect and disinfect the laundry, it is often necessary to add a larger dose to the large industrial washing machine while heating. Detergents, disinfectants and bleaches for long periods of washing and bleaching.

At the time of high-speed dewatering, the industrial elution machine reaches 600 rpm, and the water tank is filled with water and fabric. The high-speed centrifugal movement will cause strong sputum, and all cylinders will tremble. The tremor of the fully automatic washing machine is inevitable, and the functions of the equipment produced by various brands are different, and the trembling is different.

Nowadays, the shock absorption of washing equipment has become one of the key skill centers, but the tremor of the washing machine body will cause noise, which will affect the surrounding environment. Today's industrial washing machine is now widely used in hotels and hotels. , hospitals, all major washing plants. How to avoid the noise of the washing equipment to affect the surrounding environment?

Nowadays, many hotels and hotels have built their own laundry rooms. However, due to the elements of the occasion, many hotel laundry rooms are close to the guest rooms. The time for washing equipment will affect the guests’ rest. Therefore, in planning the laundry room, try to The laundry room should not be in the same building as the room, try to build a laundry room by yourself. However, some hotels have to build scrubbing equipment on the second floor or above due to limited occasions. Try to choose an elution machine below 30KG.

Large laundry plants have many washing equipment, and some work day and night. It is assumed that the choice is near the community, which will affect the people's rest. In the early stage of selecting the site, try to choose the laundry factory in the suburbs to minimize the noise.

Generally, according to the above tips, you can use the washing equipment without worrying that the noise generated during the work will affect other people.

1. The inner door cover of the industrial washing machine is equipped with a stainless steel safety locking mechanism. The outer cylinder door cover is provided with a travel switch, which is safe and reliable. The industrial washing machine is driven by triangular tape, which has small vibration, stable operation and durability.

2. The structure of the industrial washing machine adopts the horizontal drum type. The inner and outer cylinders of the industrial washing machine are made of high-quality stainless steel, which is smooth and bright, corrosion-resistant, and has little wear and damage to the fabric, and the machine has a long service life;

3, industrial washing machine is suitable for washing cotton, wool, chemical fiber, silk and other clothing fabrics. Stonewashing machines can be used in clothing factories to wash denim and silk and other clothing.

1. The configuration of industrial washing machines: There are many spare parts for industrial washing machines. The key is the choice of inverter, motor, computer board, bearing, sealing ring and solenoid valve.

2. The indicator of the drum type industrial washing machine is bright, but it does not enter the water; the industrial washing machine can work normally, but the maintenance of the undrained fault

3, the reason for not entering the water may be in the water inlet electromagnetic, water level switch or its control circuit. Open the upper cover first, pull out the two terminals of the inlet solenoid valve, and use the multi-meter AC voltage block.

4, measuring the voltage at both ends: If there is no voltage, the fault may be in the water level switch or control circuit, if the voltage is normal, the array may be in the water inlet solenoid valve, and then use 22ov AC voltage plus

5. In the water inlet solenoid valve coil: observe whether water is in the water. If water can be entered, the water inlet solenoid valve is normal, then check the water level switch, pull out the terminal block, and use the multimeter meter.

6. Determine whether the water level switch is normal: If both are normal, the fault must be on the water inlet control line, and each terminal and program controller can be checked. An undrained fault may be

7. Filter blockage or drain pump failure: first clean the filter, then check the drain motor to determine the cause of the fault.

Understand that the drum type industrial washing machine does not enter the water failure, then how to repair the failure of the drainage?

The problem of poor drainage is caused by the filter blockage or the bending of the drain pipe, flattening, etc., just clean the filter or adjust the drain pipe.

The size of the laundry room is considered: the industrial washing machine belongs to the large washing equipment. The 100kg industrial washing machine has 3 tons of multiple washing machines, so it is not easy to move. Therefore, the position should be considered first before purchase, and the area of the factory or laundry room should be selected according to the quantity and size of the purchased equipment. size.

Washing process: put the laundry, press the start switch, the inlet valve is energized, open the inlet valve, and supply water to the industrial washing machine. When the water supply reaches the predetermined water level, the water level switch is turned on, the water inlet valve is turned off, and the water supply is stopped. The washing motor is powered on, and the pulsator is rotated to form a washing water flow. Through the motor's non-stop forward rotation, stop rotation, reverse rotation, repeated circulation, the formation of washing water has a strong tumbling effect on the laundry, and at the same time, mutual friction and impact force between the clothes, the clothes and the surrounding barrel wall, This achieves the purpose of washing clothes.

What do you know about the soaking and maintenance of the washing machine? So before you wash it with linen, it is better to soak it in cold water for a while.

1. It can make the dust and sweat attached to the surface of the cloth get out of the cloth and enter the water, which can improve the washing quality of the cloth and save the detergent.

2. The penetration of water can be utilized to fully expand the fabric before it enters the washing liquid, so that the dirt in the cloth eye is squeezed to float on the surface and is easily removed.

3. Some color fabrics with poor washing fastness are easy to decolorize. Pre-soaking can find these problems in time, and it is convenient to take preventive measures during the washing process. The amount of water soaked in the cloth should be sufficient. The soaking time should be determined according to the variety, material, old and new, dirty and dyeing fastness of the clothes.

Washing machine maintenance method

In general, the maintenance of industrial washing equipment is divided into routine maintenance and regular maintenance. Daily maintenance mainly includes: cleaning, wiping, lubrication, adjustment, etc.

Tools/materials working objects: washing machine, industrial dewatering machine, dryer, fully automatic washing machine, ironing machine, folding machine / common machine tools, cleaning tools.

Step / method

1. Clean the inner cylinder and outer wall of the machine, and keep the residue of oil and detergent in the wall, gear box, panel, etc.; no leakage, gas leakage, oil leakage, etc. in various parts and seals; water, steam, Drainage, no obstruction of the exhaust port, no corrosion.

2, the machine's accessories, common tools, the pipelines involved, etc. are intact and intact, placed in an orderly manner, no safety hazards.

Check the oil pressure, air pressure and water level of the machine. Regularly add lubricating oil to ensure no oil breakage and no dry rotation. The oil quality meets the requirements. Whether the operation in daily work complies with the safe operation rules, whether there is overload operation, whether the machine safety protection device is complete without loss, whether it can work normally, and whether there is a fire hazard.

Washing machine installation

1. When the washing machine is transported by the manufacturer to your laundry room, you must first conduct a routine inspection of the washing machine to check whether it is the machine you purchased and whether it is damaged or unusable during the transportation process. If you have problems, take photos and contact the manufacturer immediately.

2. Before washing the machine, you should determine the installation position of the washing machine. The selection of the washing machine installation position should consider the position of the transportation channel, raw material turnover, water inlet, steam inlet and sewer pipe. Here, the net cleaning machine reminds you that the washing machine should be installed and Dewatering machines, dryers and other equipment together reduce the distance between these devices and prevent subsequent troubles caused by improper selection of locations.

3. The washing machine belongs to a large and heavy-duty laundry equipment, so the machine should be installed on a solid foundation, and at the same time, it should be kept horizontal to prevent the equipment from working due to the uneven location of the site and the installation location. Large vibration, which affects the washing efficiency and the service life of the washing machine.

4. Refer to the instruction manual of the washing machine, find the washing machine electrical control cabinet door according to the relevant content in the manual, and connect the 380V three-phase power line and the neutral line according to the binding post (the need to remind here is: the electricity consumption of the washing equipment) Must be 380V, no access to low voltage or high voltage).

First, we must pay attention to the daily maintenance of industrial washing machines:

1 After a laundry cycle, the button collector should be cleaned to reduce the load on the pump, prevent the pump from clogging, and prolong the life of the pump. After every three laundry cycles, the ciliary collector should be cleaned to increase the flow of wind during drying and shorten the drying time. Reduce the adhesion of cilia on the recovery condenser and reduce corrosion on the recovery condenser;

2 Check the pneumatic three components daily to drain the water to prevent moisture from entering the solenoid valve and air valve, causing them to be damaged prematurely. When the oil level is insufficient, add lubricating oil to ensure sufficient lubrication of each bearing and prolong the bearing life.

3 Check the working pressure of the filter at any time. When the pressure reaches or exceeds 1.5-2KG/cm2, the filter should be cleaned. Only reduce the outlet pressure of the pump and prolong the life of the pump. Clean the tank once every 5-8 times. Thereby increasing the distillation speed, and at the same time reducing the corrosion of the sludge on the bottom plate, thereby achieving the purpose of extending the life of the distillation tank;

 Second, the next step is to carry out phased maintenance of the industrial washing machine (usually one stage per month):

1 Check the tension of the industrial washing machine belt to ensure the normal washing speed and drying speed, check the belt wear and replace it in time. Check the pH of the polyester solvent. If the pH value is found to decrease, adjust it to prevent corrosion of the dry cleaning machine, thus extending the life of the dry cleaning machine.

2 thoroughly clean the cilia around the machine to prevent the ciliary block the air passage, reduce the corrosion of the dirt adsorbed by the cilia; check the performance of each trap and clean the filter on the steam line and the cooling water pipe to improve the efficiency of the machine. Energy saving. Check and clean the solvent pump to prevent dirt that is clogged in the pump from damaging the impeller of the pump and increasing the outlet pressure of the pump, damaging the seal.

 Third, the annual industrial washing machine maintenance work can not be ignored. (Each industrial washing machine needs to be thoroughly maintained every year):

1 Thoroughly clean the cilia attached to the cold coil, the hot coil and the air flow passage to improve the drying and recovery efficiency and reduce the corrosion of the dirt on the machine.

2 Discharge and clean the oil-water separator to ensure normal separation of oil and water.

3 Clean the distillation condenser and related piping, preferably with baking soda water to neutralize the acid of the dry cleaning oil to extend the life of the machine.

4 Thoroughly clean the solvent tank and thoroughly remove the dirt deposited in the bottom box to ensure the quality of the dry cleaning oil and extend the life of the machine

First, when the ironing machine is turned on, turn on the power. First check if the safety device is normal (note that the pressure roller cannot be placed directly in the tank when the machine is cold), then slowly open the steam valve and heat up for about 20 to 30 minutes. Put down the pressure roller, wax the cleaning wax cloth and clean the groove surface, set the working speed according to the temperature reached by the heating, the type of the fabric and the moisture content (generally for the cotton fabric, the multilayer fabric selects the lower ironing speed, for The chemical fiber or thin fabric can be ironed at a higher speed. The ends of the fabric are flattened and ironed, and the parameters are adjusted according to the ironing effect. After the work is completed, the cleaning waxing operation is performed again, the steam valve is closed, and the bypass valve is installed to open the bypass valve to discharge the condensed water, and the moisture on the hot felt is removed to keep it dry.

In the process of normal use of the machine, if it is found that the cloth is wrinkled, the groove surface should be cleaned in time. Frequent waxing also extends the life of the tank and felt; for mild dirt, it can be removed with a cleaning cloth in combination with a wax cloth; for more serious dirt, it needs to be removed with a special cleaning agent; if the dirt is very serious, then It must be cleaned by hand when the machine drum is raised to the service state (be careful not to damage the groove surface).

The ironing machine roller is heated by steam or electric. After reaching a certain temperature, the wet clothes are rolled between the two rollers, which can remove a large amount of water and achieve the effect of ironing.

Take the sheets as an example, the ironing process is as follows:

1. Check if the electricity, gas and equipment are operating normally. Pressure should reach 7-8KG/CM, compressed air 6KG/CM

2. Turn on the power, steam, and compressed air switches in sequence.

3, the sheet ironing machine needs to preheat for 15 minutes before work, until the temperature rises above 160 degrees and then lower the drum.

4. Before pressing the sheets, first remove the wax cloth and clean them. The wax powder should be wrapped in the wax cloth. Do not sprinkle it on the roller and press it at least three times.

5, all damaged or vacant hot strips should be replaced, the degree of tightness of the hot strip should be moderate.

6. When ironing the sheets, pay attention to the two corners and straighten them. The two ironing machines are separated on both sides of the machine. Pinch the two corners and feed them into the conveyor belt of the sheet ironing machine. Use the hand to droop the drooping cloth. Pull and feed smoothly.

7. Pay attention to adjust the speed of the drum when ironing, and the sheets that are burned should not be wet or wrinkled.

8. In the operation of the sheet ironing machine, pay attention to the sheet fabric that needs to be washed back or reported damage. If you fold a corner, you must return it to the wash.

9. When ironing sheets, it is required to flatten the movement quickly.

10, after the sheets are hot, the four sides should be neat and creased, keep the original shape, the front is shiny, and the bottom corner is not elongated.

11. When folding sheets, the creases should be clear and there should be no clutter.

12. The number of sheets that are flattened should be statistically accurate and recorded.

13. After the operation is finished, stop the sheet ironing machine, lift the sheet ironing machine, place the operation panel stop button in the stop position, cut off the power, and close the steam and air compressor lines.

14. After the work is finished, wipe the dust on the surface of the sheeting machine, especially the roller.

15. Organize the sheets of the sheets and arrange them neatly.

16. Remove debris, batt, etc. from the bottom of the sheeting machine and the surrounding ground, and do a good job in the work area and turn off the power switch.

1, do the lightning protection work of the dehydrator

The maintenance of summer dewatering machine is focused on lightning protection. Lightning strikes not only cause devastating damage to the electrical components of the dehydrator, but also cause fire, injury, and property damage.

2, do the rust prevention work of the dehydrator

In summer, the temperature is high and the humidity is high. Especially the plastic dewatering machine and the dehydrator which often contact with the acid-alkaline solution are easy to rust. Therefore, each dewatering machine manufacturer must do the summer anti-rust work of the dehydrator. The dehydrator is waterproof and isolated.

3, do the waterproof work of the dehydrator

It is rainy in summer, and many dewatering machine processing enterprises have leaked or accumulated serious water after the rainy season. This also seriously affects the safety and service life of dewatering machines such as plastic dewatering machines. It is necessary to strengthen the inspection and waterproof repair of the water leakage of the factory.

4, do a good job in the dehydration plant safety work

Many dewatering machine processing enterprises are located on river banks or other low-lying areas due to the demand for water sources. After the rainy season, pay special attention to the safety of the dewatering plant. Prevent the damage of dehydration machine production plants by natural disasters such as floods and mudslides

1. The processing precision and strength of the whole mechanism frame are transmitted by the transmission belt, and the belt is driven by the transmission shaft. The transmission shaft is fixed on the whole mechanism frame through the bearing. The processing method of the frame, the processing precision directly determines the folding precision, especially the processing precision of the left and right side plates (the front and rear side plates) on the frame, the verticality of the assembly, the parallelism and the design strength of the whole frame. Generally, the two side plates are processed by a laser cutting machine to ensure that all the holes of the left and right plates and the bearing fixing holes are completely identical. The frame is welded on the platform by assembly welding tooling to ensure that the base is perpendicular to the side plates, and the plates on both sides are parallel to each other, so as to ensure the accuracy and quality of the whole frame.

2. There are a lot of transmission shafts for the material and machining accuracy of the drive shaft. Taking a 50% discount of a certain model as an example, there are 7 longitudinal drive shafts and 14 transverse drive shafts. These shafts form a three-conveyor loop with longitudinal one-to-two fold and platform transport, and a transfer loop such as a lateral fold, a lift fold, and a fifth fold. The roundness and straightness of the drive shaft are one of the key qualities, and the roundness and straightness depend on the material and processing of the shaft. Generally, the cold drawn seamless pipe is welded and the shaft head is welded, and finally the outer circle and the two shaft heads are machined by the machine tool, so that the roundness and straightness of each axis can be ensured. If welded pipes are used, it is difficult to guarantee quality.

3, the quality of the bearing and its assembly process determines the reliability and the size of the noise. The drive shaft is fixed on the whole frame by bearings. For the above example, nearly 50 bearings (including the drive sprocket) are used. It is obvious that the bearing is in the middle. Generally, manufacturers use better bearings, such as imported nsk bearings. It is assembled with light pressure and assembly during assembly to ensure the parallelism between the drive shaft and the drive shaft. Each drive shaft can be easily rotated flat under free conditions.

4. The quality of conveyor belts and optoelectronic devices is a major factor affecting reliability. There are many conveyor belts, such as ordinary conveyor belts and special static electricity transmission belts. These conveyor belts must be manufactured by professional manufacturers, subjected to strict heat setting treatment, and equipped with a good high-pressure rubber seal joint. The length error of the conveyor belt is less than 0.5%, and the static static conduction resistance of the special static elimination belt is less than 0.5 ohm/meter. A number of optoelectronic devices, such as photocells and frequency counters, are used to determine the transport speed of the conveyor belt and the fabric to determine the fold size of the fabric. Due to the frequent use and high quality of these devices, it is necessary to use the products of the brand manufacturers, otherwise the reliability will be seriously affected.

5, fabric length system is the key to determine whether the accurate folding is to start from measuring the length of the folded fabric, only the length of the fabric is accurately measured, the speed of the belt can be accurately positioned for folding. For example, when the fabric has not completely left the ironing machine, its conveying speed is equal to the speed of the ironing machine, and when it leaves, it is the speed. To accurately calculate the length of the boot, the speed of the fabric and the speed of the belt must be measured separately. In addition, the frictional slip between the drive shaft and the belt must be considered. Therefore, the merits and demerits of the fabric length measurement system are another important factor in judging quality. Generally, an excellent system will use three-speed measurement (shaft speed, belt speed, cloth speed) plus one-fold positioning technology to complete accurate measurement and folding work.

First, look at the thickness of the whole frame material

Regardless of whether it is a sheet folding machine or a towel folding machine, the two side plates of the frame are the force-receiving members supporting a large number of transmission shafts, and the type steel plate should be used, and the thickness should be not less than 8 mm. Different types of folding machines may be different, here refers to bed sheet folding machines and large towel folding machines.

Second, check the roundness and straightness of each transmission axis

You can ask the manufacturer, what kind of steel pipe is used for the drive shaft, whether it is ordinary steel pipe, welded pipe or cold drawn pipe, how it is processed to ensure its roundness and straightness. It is also possible to observe whether the drive shaft is bouncing during the operation of the folding machine, and whether the conveyor belt is elastic or not. As long as there is jumping and tightness, the transmission shaft has defects of not being round and straight.

Third, observe the quality of the folding machine drive shaft assembly

Verify the parallelism of the drive shaft. The center distance of the two transmission shafts, that is, the distance between the centers of the two shafts, can be measured from the left and right side plates of the folding machine, and the error between the two should be less than 3 mm. It is also possible to measure the center distance of each axis two or two on the front and rear side plates of the transverse frame to determine the assembly parallelism.

Check the parallelism of the left and right work or the front and rear side panels of the whole mechanism. It can be observed while the folding machine is running at no load to see if there is a slight vibration in the axial direction of the drive shaft. If there is vibration, the strength of the side panels is insufficient or there are factors that are not parallel. It is also possible to measure the axial distance of the lower left and right corners on the side plate of the static measurement, and the error value should be less than 5 mm.

Inspect the assembly quality of each bearing of the whole frame. It can be observed while the folding machine is running at no load. Beside the left and right side plates, beside the front and rear side plates, carefully listen to the sound of each drive shaft bearing. It should be a uniform slight hum, and there should be no irregularities. The crackling sound. Otherwise, check the bearing status of each drive shaft separately or repeat the above checks.

With the improvement of people's quality of life, industrial washing equipment such as ironing machines, washing machines, folding machines, dryers, etc. are more and more widely used in our production and life. To further help users learn more about washing, here is a brief talk about the difference between industrial washing equipment and household washing equipment.

1. Industrial washing equipment has large capacity and various types. Industrial washing uses special washing equipment to ensure high quality, high efficiency and large-scale washing. The washing capacity is larger than that of household washing equipment, and the variety and specifications are more complete.

2. The business scope of industrial washing is wider than that of households. Industrial washing not only includes the cleaning of light linen fabrics such as bath towels, pillow covers, bed sheets, quilt covers, etc., but also the washing of heavy-duty fabrics such as tablecloths and napkins (snookers) in restaurants and restaurants, and railway trains. Washing of passenger linen and hospital fabrics. It should be said that the industrial linen washing business includes the cleaning of almost all fabrics such as clothes worn by people in daily wear except for dry cleaning. More than 80% of the laundry business is done by washing.

3. The difference in the quality of industrial washing staff. Those who are engaged in professional industrial washing operations should have more and more comprehensive technical knowledge than household washing personnel, including not only the physical and chemical properties of textile fibers, the types and removal methods of stains, but also the detergents. Features and applications, maintenance and repair of washing equipment. Copyright by:www.xdjx888.com

4. The difference between washing equipment and washing materials. Industrial linen washing uses a complete set of special washing materials to ensure the decontamination, sanitation and maintenance of the fabric. For household use, you can use detergent or laundry detergent.

1. The folding machine manufacturer maintains the folding machine to extend the service life of the folding machine, which is equivalent to saving the capital needed by customers to purchase new equipment and creating more value for customers. The folding machine manufacturer has always been adhering to the customer's point of view, for the sake of customers, and strive to improve the quality of the folding machine, to provide greater help for customers seeking folding machine.

2. It can guarantee the quality of the folded products to be more excellent, ensure the production level of the folding machine manufacturers, retain the old customers, and attract more new customers.

In fact, the paper folding machine feeds paper into the middle of the two rollers through the paper feed roller, enters the position where the first folding tray is set, and then enters the position where the second folding tray is set, and then pours out through the indentation shaft into the conveyor belt to send out! Origami styles mainly include folds, crosses, report folds, inner three folds, outer three folds, and Guanyin folds. At present, the paper folding machine products are very popular in the market, the price is low, and the working ability is strong, which brings great convenience to the enterprise!

Drying equipment is a very good equipment. The drying performance of this equipment is very good, so it is used in many places, but this kind of equipment needs to pay attention to the purchase skill when it is used, otherwise it is very Hard to buy the right one. So, what are the basic purchasing techniques for drying equipment?

First, the drying process

The drying process includes determination of drying time, drying temperature, dry atmosphere, and the like. The material precursor is a low-priced compound of a variable-valent metal that is oxidized in the air, and the higher the drying temperature, the more severe the oxidation. However, since vacuum drying and inert atmosphere protection have high drying cost and low drying efficiency, and the quality of the precursor dried at an appropriate temperature in an air atmosphere can basically meet the requirements, the air atmosphere is generally selected to be dried.

When it is determined that the drying temperature of the precursor cannot be higher than 150 ° C, the moisture content may be less than 1% according to the drying efficiency of the drying device and the precursor moisture control standard, and the drying time required for different drying devices is different.

Second, drying equipment

Drying can be classified into conduction drying, convection drying, radiation drying, dielectric drying, and joint drying depending on the mode of conduction.

At least the following points need to be considered when selecting a dryer for the material precursor:

Product moisture content requirements;

The moisture content of the filter cake and the water content of the filter cake are uniform;

Dryer production capacity, material feeding mode;

The material of the contact part between the dryer and the material precursor needs to be alkaline resistant and cannot carry metal impurities or other impurities;

The drying temperature to be achieved, etc.

The material precursor can be dried by a hot air circulating oven, a rotary dryer, a tray dryer, a rake dryer, a microwave dryer or the like.

Advantages: easy loading and unloading, small material loss, easy to clean the tray. Therefore, the advantages of the van dryer are remarkable for products that require frequent replacement of products, high-priced finished products or small batches of materials.

The disadvantages are: the material is not dispersed, the drying is uneven, the drying time is long; the loading and unloading materials are time-consuming, labor-intensive, labor-intensive, and the equipment utilization rate is low; the dust is flying when the material is unloaded, the environmental pollution is serious; the thermal efficiency is low, generally 40 About %, about 2.5 kg of heating steam is consumed for every 1 kg of water to be dried

I don't know if you usually use the drying equipment to take the initiative to understand the relevant knowledge, because there are a lot of technical knowledge in the use of drying equipment, you need to understand. Here is a brief introduction to everyone here, let everyone know about the heat transfer methods of drying equipment.

The drying device is a low-speed stirring dryer which is provided with a stirring slurry inside the device to make the wet material fully contact with the heat carrier and the hot surface under the agitation of the blade to achieve the drying purpose. The product can indirectly heat or cool the paste, granular, powder, and slurry materials, and can complete unit operations such as drying, cooling, heating, sterilization, reaction, and low temperature combustion. The special wedge-type stirring heat transfer blade in the equipment has high heat transfer efficiency and self-cleaning function of the heat transfer surface.

The structure of the drying equipment is generally horizontal, two-axis or four-axis, and the heat transfer mode is divided into hot air type and conductive type. The hot air type is in contact with and dried by a heat carrier (such as hot air), and the heat medium in the conduction mode is not in direct contact with the material to be dried, but the hot surface and the material are in contact with each other.

Drying equipment features:

1. Low energy consumption of the paddle dryer: Due to indirect heating, there is not a large amount of exhaust gas to take away heat, and the outer wall of the dryer is provided with an insulation layer. For the slurry material, only 1.2 kg of water vapor is required to evaporate 1 kg of water.

2. The blade dryer system has a low cost: it has a huge heat transfer surface in the effective volume of the unit, which shortens the processing time and reduces the size of the device. It greatly reduces the building area and building space.

3. Wide range of processing materials: Different heat media can be used to process both heat sensitive materials and materials that require high temperature treatment. Commonly used media are: water vapor, heat transfer oil, hot water, cooling water, etc. It can be operated continuously or intermittently and can be applied in many fields.

4. Small environmental pollution: no air is used, and dust materials are rarely entrained. The solvent evaporation of the material is small and easy to handle. Closed loops can be used for contaminated materials or for conditions requiring recovery of solvents.

5, low operating costs: low-speed mixing and reasonable structure, so that the amount of wear is small, maintenance costs are very low.

6. Stable operation: Due to the special compression-expansion agitation of the wedge-shaped paddle, the material particles are fully in contact with the heat transfer surface. In the axial interval, the temperature, humidity and mixing gradient of the material are small, thus ensuring Process stability.

1. Warehouses, libraries and archives: in low humidity, products, books and documents, the environment will not be broken for a long time.

2. Pharmaceutical industry: Widely used in this process to control the humidity of the parameterized industry, for example, soft gelatin capsules, fluidized beds, tablet presses, coaters, tumble dryers, tray dryers, etc.

3. The electronics industry, which is widely used in precision instruments, such as electronic components, components, aerospace, lithium, etc., which require strict humidity control.

4. Chemical fiber industry: used with chillers, can make dew point below -40 °C to meet the dry environment of polyester chips in chemical fiber plants.

5. Food processing industry: suitable for dehydrated vegetables, chocolate, candy, chewing gum manufacturing, cube flour processing, fermentation, drying and other processes.

1. High thermal efficiency. Because the heat transfer mechanism of the drum dryer is heat conduction, the heat transfer direction is consistent throughout the operation cycle. Except for the cover heat dissipation and heat radiation loss, the rest of the heat is used for the evaporation of the wet film of the tube wall, and the thermal efficiency can reach 80%. -90%.

2. The operation is flexible and adaptable. Many drying factors of the drum dryer can be adjusted. For example, the concentration of the feed/the thickness of the coating film, the temperature of the heating medium, the rotation speed of the drum, etc. can all change the drying efficiency of the drum dryer, and many factors are not involved. This brings great convenience to the drum drying operation, so that it can adapt to the drying of various materials and different production requirements.

3. Short drying time. The drying cycle of the material is generally only 10-15 seconds, which is suitable for heat sensitive materials. If the drum dryer is placed in a vacuum, it can be operated under reduced pressure.

4. The drying rate is large. Since the film applied to the wall of the cylinder is very thin, generally 0.3-1.5 mm, and the heat transfer and mass transfer directions are the same, the evaporation surface strength of the film can be maintained at 30-70 kg.h2o/m2.h.

After a long period of use, the washing equipment will inevitably breed a lot of bacteria. If the bacteria are not treated, it will be attached to the clothes washed by the washing equipment, and then it will cause certain damage to the human body. Therefore, when you use washing equipment, you must do regular disinfection work is the most important.

Many people have not noticed such a problem during the use of washing equipment. Whether it is household or laundry-specific washing equipment, everyone puts clothes directly into the equipment for cleaning, but the equipment is not in place before the clothes are put in. After cleaning, the clothes are twice contaminated.

Although there will be washing powder and laundry detergent in our washing process, these can not replace the professional disinfection products to completely disinfect the washing equipment, and it is easy to breed a lot of germs. The washed clothes seem to be clean, but it is not. So we have to develop the habit of regularly disinfecting the washing equipment.

For example: a washing machine can generally be used for more than 10 years. If it is not cleaned, the bacterial over-standard rate of household washing equipment can be as high as 81.3%. The growth conditions of the fungus are generally between 0 ° C and 45 ° C, and the temperature of the washing equipment water is generally 20 ° C, which is just the suitable temperature for fungal growth. Fungi can cause skin diseases such as ankles, handcuffs, and tinea versicolor, and even gynecological diseases, allergic dermatitis, and asthma.

Here, we also remind you that the daily washing equipment can be opened for 2-3 hours after use, to achieve the effect of ventilation and dehumidification, and then regularly cleaned and disinfected to ensure the genuine cleanliness of clothes and sheets.
