There are two methods of drying: the drying room method and the mechanical drying method.
(1) Dry cleaning store technology drying room method
In a sealed room, set up a small hole of 0.1 square meters at the lower part of the oblique diagonal of the room respectively, place the heat source (such as radiator) near the small hole below. Hang the clothes containing water in the room. The heat source heats the air in the room, hot air rises from low to high, passes through the water-containing fabric and evaporates the moisture, then carries the humid hot air out through the small hole above the room. While the small hole below is responsible for air replenishment. After this process continues for a period of time, the fabric will be dried. This drying method is 4~8 times more efficient than the natural drying method, suitable for some small laundry factories.Dry cleaning store chain

The mechanical drying method usually refers to the method of drying fabrics using fabric drying equipment. There are currently two types of equipment commonly used in mechanical drying: one is a dry cabinet; the other is a rotary drum dryer.
Dry cabinet Generally, the dry cabinet looks like a large wardrobe on the outside. The cabinet shell is made of steel plate, with an insulation layer inside, and it is divided into two parts: the upper part is the drying area, equipped with exhaust louvers, occupying 5/6 of the cabinet height; the lower part is the heat source and fan air inlet, occupying 1/6 of the cabinet height. Hang the washed fabric in the drying area of the dry cabinet, close the door, the fan rotates simultaneously, the air enters the cabinet through the air inlet hole, contacts the heating element and gets heated, then enters the drying area and contacts the wet fabric, making the moisture evaporate; the humid hot air is discharged through the exhaust louver. The exhaust fan keeps working, supplementing hot air, continuously forcing the circulation of damp clothing, after a period of time, when the moisture on the damp clothing has completely evaporated, the clothing is also dried. The advantage of this drying method is that the equipment is inexpensive and the operation is simple. Since the clothing is hung to dry, there are relatively fewer wrinkles. However, the efficiency is relatively low and is generally suitable for drying special fabric clothing after hand washing.
Rotary drum dryer There are generally two types of rotary drum dryers. One type is steam-heated, and the other is electrically heated. The main difference is the different heating methods of the heat exchanger. The heat exchanger of the steam-heated type consists of copper pipes and copper fins, with steam providing the heat source; the heat exchanger of the electrically heated type consists of electrical heating elements (such as resistance wires), heat transfer devices, and fins, converting electrical energy into thermal energy through heating wires. The dryer is equipped with a heating time controller and a cooling time controller. The heating time controller can control the heating and drying time of the items being dried, while the temperature controller inside the dryer ensures the constant set working temperature. There is a temperature sensor at the outlet of the hot air in the drum of the dryer, which feeds back the detected temperature signal to the temperature controller to achieve automatic temperature control. During the rolling process of the fabric being dried in the dryer, a considerable amount of fiber fluff will fall off and be carried out by the hot air. These things will pollute the external environment, block the pipelines, and may cause static electricity due to intense friction between them, leading to fires. Therefore, a filter is also installed at the air outlet of the drum, which has a retarding effect on the fluff. However, for this reason, the fluff will clog the holes of the filter during the drying process, causing poor air circulation and affecting the drying effect. Therefore, the filter should be checked and cleaned according to plan. In order to ensure the normal operation of the dryer and safe production, attention should be paid to the following points during use:
(1) Clothes contaminated with flammable substances such as dry cleaning solvents, banana oil, paint, gasoline, mechanical oil, and cooking oil are absolutely prohibited from using the dryer, otherwise there is a possibility of fire.
(2) Clothes containing sponges, rubber, pads, and plastic items, wax should not be dried in the dryer.
(3) The weight of the clothes to be dried should be appropriate, generally 80%~85% of the rated loading capacity.
(4) If the weight of the items to be dried is too light, find similar items to dry together, otherwise the items to be dried will stick to the drum due to the centrifugal force generated by the rotation of the dryer drum, making it difficult to dry.
(5) Pure wool fabrics and fabrics that are easily contracted by heat should not be dried in the dryer.
(6) For some clothes that are prone to fading, if they fade when heated, do not use the dryer to dry them.

During the washing process, fabrics are affected by factors such as washing mechanical force, thermal energy, and mutual friction between fabrics, which can cause deformation of the fabric. For example, during water washing, the fabric expands or contracts due to the action of water; during dry cleaning and drying, the fabric loses its original shaping effect when heated. Ironing is the process of straightening it to restore the original shape of the fabric and leather products. If the clothes are washed very clean but poorly ironed, people will still feel disappointed. Therefore, "washing is the essence and ironing is the appearance."
Six, Dry cleaning store technology packaging
Packaging is the last step in the washing process. Washed and ironed clothes should be classified and packaged separately. Before packaging, the washed and ironed clothes should be inspected. It is divided into manual packaging and mechanical packaging. Generally, shirts and underwear should be fully enclosed packaging; outerwear can be bagged packaging. The hangers used for packaging should be made of environmentally friendly materials, and black plastic hangers (recycled plastic) should not be used, otherwise they may cause secondary pollution to the clothes. After packaging, professional quality inspectors should conduct a comprehensive quality inspection of the clothes, and only after passing the inspection can they be placed in the pick-up area for temporary storage, either by delivery personnel or waiting for customers to pick up the clothes.
Seven, Dry cleaning store technology sending
Check the customer's pick-up receipt according to regulations, or handle related procedures for handover. At the same time, answer the questions raised by customers, make records, and promptly feedback relevant issues to relevant personnel (departments).
