High efficiency dehydrating refrigeration dryer

Air cooled refrigerated dryer

Plate heat exchanger Air Dryer, small volume, low noise, low energy consumption, low pressure dew point,the highest intake 45 degrees, full load operation dew point: -2*C—3 *C。Optional 8-30Bra, aluminum or stainless steel heat exchanger

Fengli series freeze dryer consists of heat exchange system, refrigeration system and electrical control system. Compressed air first enters the pre-cooler for gas-air or gas-water heat exchange, and then goes into the cold-heat exchanger to exchange heat with the cold air cooled to the pressure dew point through the evaporator, which further reduces the temperature of compressed air. After that, compressed air enters the steam exchanger, exchanges heat with refrigerant, separates through the steam-water separator, and discharges through the exhaust valve, while the dry low-temperature air enters the cold-heat exchanger, and the heat exchange is heated and exported.Air Dryer
Fifteen years of professional experience,we not only focus on research and development and equipment manufacturing in the field of compressed air purification, but also through our understanding and summary of manufacturing industry, can provide users in all walks of life with more economical and efficient comprehensive compressed air purification solutions.Air Compressor

I. Working principle of refrigerated dryer

The refrigeration dryer uses refrigeration technology and vacuum technology. First, the material to be dried is put into the refrigeration equipment for freezing and freezing. The material is cooled so that moisture starts to form ice in the material. The material in the refrigeration equipment is then placed into a vacuum chamber in order to convert the material from ice to gas by direct evaporation. The air in the vacuum chamber is pumped out so that the lower temperatures and pressures slow or stop the chemical reactions. This process slowly raises the cooling temperature of the material so that the moisture within the material is directly converted from a solid state to a gaseous state, thus removing the moisture and drying the material.Water Chiller

Second, the advantages of the refrigerated dryer

1、Wide range of application: the refrigerated dryer is suitable for drying various materials, especially materials that are easy to deformation, easy to oxidation, easy to decomposition, high heat sensitivity, etc.

2, the best drying effect: in the freezing and vacuum conditions, the material in the moisture separation and drying process almost no "thermal stress", therefore, its maintain the original physical and chemical properties.

3. Retaining the original flavour: as freeze drying uses low temperature drying, the original flavour, colour and nutrient content of the material can be retained to the greatest extent possible and the added value of the product can be increased.

4、Routine operation: As freeze dryers are widely used in pharmaceutical, food, biological and chemical industries, they are widely recognised for their convenience in operation and maintenance.
