Refrigeration Air Dryer
Working principle:
Inlet temperature:≤80℃
Cooling method:Air-cooling
Inlet pressure:0.4-1.0MPa
Pressure drop:≤0.03MPa
Dew point:3-10℃
Refrigerant:R22
The refrigerated compressed air dryer is based on the principle of air freeze drying. It uses refrigeration equipment to cool the compressed air to a certain dew point temperature, precipitate the corresponding water content, separate the gas and liquid through the separator, and then discharge the water through the automatic drain valve. Thus, the purpose of freezing and dehumidification is achieved. At the same time, solid dust particles and trace oil components of 3μm and above in the compressed air are filtered out, so that the air source quality meets the requirements of cleanliness and dryness.

Process Flow Diagram
1.Food industry: Refrigerated dryers are widely used in the food industry and can be used to freeze dry various foods, such as fruits, vegetables, meat, etc. Freeze drying can maintain the original taste and nutrients of food, extend its shelf life, and reduce the volume and weight of food, making it easier to store and transport.
2.Pharmaceutical industry: Freeze dryers also play an important role in the pharmaceutical industry. Through freeze drying technology, moisture can be removed from pharmaceutical preparations, thereby extending the shelf life of the medicine and maintaining the active ingredients of the medicine. In addition, freeze dryers can also be used to prepare biological products, vaccines, etc.
3.Chemical industry: In the chemical industry, refrigerated dryers are mainly used to dry chemical raw materials, intermediates and finished products. Through freeze drying technology, moisture in the substance can be effectively removed, the purity and stability of the product can be improved, the volume and weight of the product can be reduced, and storage and transportation can be facilitated.
4.Laboratories and scientific research fields: Refrigerated dryers are also widely used in laboratories and scientific research fields. Researchers can use refrigerated dryers to freeze-dry samples to maintain the original structure and properties of the samples, which is convenient for subsequent analysis and research.
5.The chemical and metallurgical industry： Including instrument gas, power implementation, machine equipment blowing, process assistance, etc., is also an industry field that cannot be separated from refrigerated dryers.
6.The chemical fiber textile industry mainly uses compressed purified air to provide clean gas power for jet looms, sizing machines, printing and dyeing machines, roving machines, and suction guns, and generally uses refrigerated dryers.
7.Semiconductor industry: This is an emerging industry, in which chip oxidation equipment, vacuum systems, pneumatic control valves, pneumatic conveying equipment, etc. must cooperate with the dryer to carry out work.
8.Power industry: The functions of cold dryers include pneumatic conveying, dry ash transportation, pneumatic execution, and instrumentation.
9.Tire industry: This is different from the automobile manufacturing industry mentioned above. For example, the functions of cold dryers in the tire industry include promoting silk cord cutting machines, rubber vulcanizers, etc., as well as pneumatic mixing and pneumatic forming.
