Freeze dryer: Working principle of a freeze dryer
The company mainly operates various compressed air after-treatment equipment, including modular dryers, zero-air-consumption dryers, regenerative blow-air dryers, combined dryers, wholesale combined dryers, waste-heat regenerative dryers, compression heat dryers, adsorption dryers, refrigeration dryers, precision filters, and other equipment.
Working principle of refrigerated air dryer:
The ultrafiltration refrigerated dryer is based on the principle of refrigeration and dehumidification. It uses a fully enclosed compression refrigeration system to cool and reduce the temperature of the compressed air discharged by the air compressor, causing a large amount of saturated water vapor and oil mist to condense into droplets. After gas-water separation, it is discharged by an automatic drain.
The saturated compressed air at a higher temperature enters the pre-cooler of the refrigerated dryer, where it exchanges heat with the dry cold air from the evaporator, and after the temperature is lowered, it enters the evaporator of the refrigeration system for a second heat exchange with the refrigerant vapor, reducing its temperature to near the evaporation temperature of the refrigerant.
During the two cooling processes, the water vapor in the compressed air condenses into liquid water droplets and enters the gas-water separator with the airflow. The separated liquid water is discharged from the machine by an automatic drain. The lower-temperature dry compressed air enters the pre-cooler and exchanges heat with the newly entered wet saturated gas, raising its temperature. As a result, the dryer's exhaust port obtains dry compressed air with a lower water content (i.e., lower dew point) and relatively low humidity.
Refrigerated air dryers have become the preferred choice for air compressor station purification equipment in various industries due to their reliable operation, convenient management, and low operating costs.
Refrigerated air dryer model specifications and parameters:
The refrigerated air dryer uses Bitzer or equivalent refrigeration compressors, which are reliable in performance and ensure long-term and stable operation of the equipment.
The refrigerated air dryer uses Danfoss or equivalent thermostatic expansion valves, which can automatically adjust the amount of refrigerant supplied based on the load of the dryer, thus achieving energy saving.
