freeze dryer sale

The Freeze Dryer consists of refrigeration system, vacuum system, heating system and electrical instrument control system. The main components are drying ovens, condensers, refrigeration units, vacuum pumps, heating/cooling devices, etc. Its working principle is to freeze the items to be dried below the triple point temperature, and then vacuum the solid water (ice) in the product to directly sublimate into water vapor, remove from the items, and make the items dry. After the material is pre-treated, it is sent to a quick-freezing chamber for freezing, then sent to a drying warehouse for sublimation and dehydration, and then packaged in a post-processing workshop.
Freeze dryer (referred to as cold dryer) Overview (classification and technical parameters)
After the air compressor is compressed, the rear cooler is cooled, the air-water separator is separated, and the compressed air after the buffer tank is regulated is generally saturated. The relative humidity is 100%, and contains impurities such as oil and solid particles. Compressed air cannot be used directly. Drying equipment such as freeze dryers are required for drying and purifying.
Main components: refrigeration compressor, dry filter, hot gas bypass valve, expansion valve, wind condenser, refrigerant pressure meter, refrigerant low pressure meter, pressure controller, electronic drain, main contactor, heat exchanger assembly, cold Dryer is based on the principle of freezing and dehumidification, the compressed air is forced through the evaporator for heat exchange and cooling, so that the compressed air in the air of water and oil after isostatic cooling, condense into liquid water and oil, and entrained with dust, through the automatic Drains drain out of the system to get clean compressed air.
