Product Description:
A freeze dryer is based on the principle of freeze dehumidification, using a fully enclosed compression refrigeration system to cool and reduce the temperature of compressed gas discharged by an air compressor. The large amount of saturated water vapor and oil mist condensed droplets contained in it are separated into steam and water and discharged by an automatic drain. The saturated compressed gas at a higher temperature enters the pre cooler of the freeze dryer, where it exchanges heat with the dry and cold gas from the evaporator. After the temperature is lowered, it enters the evaporator of the refrigeration system and undergoes a second heat exchange with the cold coal vapor, reducing its temperature to near the evaporation temperature of cold coal. During the two cooling processes, the water vapor in the compressed gas is condensed into liquid water droplets and enters the gas water separator with the airflow, where it is separated. Liquid water is discharged outside the machine through an automatic drain, The dry compressed gas with lower temperature enters the pre cooler and exchanges heat with the wet saturated gas that has just entered, increasing its own temperature. As a result, the exhaust port of the refrigerated dryer obtains dry compressed gas with lower water content (i.e., lower dew point) and relatively low relative humidity.
