Freeze Dry Machine’s Applications I

Freeze Drying Machine adopts the working principle of cooling condensation, mainly composed of three parts: heat exchange system, refrigeration system and electrical control system. The compressed air first enters the pre-cooler for heat exchange of gas or gas, removes part of the heat and then enters the hot and cold air exchanger and exchanges cold air that has cooled from the evaporator to the pressure dew point for heat exchange to make the temperature of the compressed air Further decrease.

After that, the compressed air enters the evaporator and exchanges heat with the refrigerant. The temperature of the compressed air drops to 0-8*C, and the moisture in the air is precipitated at this temperature, separated by the gas-water separator, and discharged through the automatic drainer. The dry, low-temperature air enters the hot and cold air exchanger for heat exchange, and is output after the temperature rises.

The Freeze Dry Machine uses physical principles to freeze the moisture in the compressed air below the dew point to make it from the air.

Freeze Dry Machine in the precipitation limites to the freezing point temperature of water, theoretically its dew point temperature can be close to 0 degrees. In fact, the dew point temperature of a good freeze dryer is generally about 5 degrees.

Traditional drying destroys the cells and causes the material to shrink. The structure of the sample is not destroyed during the freeze-drying process because the solid component is supported by the firm ice on its seat. If the ice sublimes, it will leave pores in the machine in the remaining material, which preserves the biological and chemical structure of the product and the integrity of activity.
