Ultimate Principle of Freeze Dry Machine

0 votes

China Freeze Drying Machine consists of a refrigeration system, a vacuum system, a heating system, and an electrical instrument control system. The main components of the Freeze Dry Machine are divided into drying ovens, condensers, refrigeration units, vacuum pumps, heating/cooling devices, etc.

The amount of water vapor in the compressed air is depended on the temperature of the compressed air: Under the condition that the compressed air pressure is basically invariable, reducing the temperature of the compressed air will reduce the amount of water vapor in the compressed air, and the excess water vapor will condense into a liquid. The Freeze Dry Machine uses refrigeration technology to dry compressed air.

The refrigeration system of the Freeze Dry Machine is a compression type refrigeration system consisting of four basic components: a refrigeration compressor, a condenser, an evaporator, and an expansion valve, which connected by a pipe connection to form a closed system in which the refrigerant circulates continuously in the system, undergoes a state change and exchanges heat with the compressed air and the cooling medium.

The refrigeration compressor draws the low-pressure (low-temperature) refrigerant in the evaporator into the cylinder of the compressor, and the refrigerant vapor is compressed, and the pressure and temperature are simultaneously increased; the high-pressure and high-temperature refrigerant vapor is pressed to the condenser. In the condenser, the higher temperature refrigerant vapor exchanges heat with the cooler water or air, so the heat of the refrigerant is taken away by water or air to condense, and the refrigerant vapor becomes a liquid.

This part of the liquid is sent to the expansion valve, which is throttled into a low-temperature and low-pressure liquid through the expansion valve and enters the evaporator; in the evaporator, the low-temperature, low-pressure refrigerant liquid absorbs the heat of the compressed air and vaporizes (commonly called "evaporation") The compressed air is cooled to condense a large amount of liquid water; the refrigerant vapor in the evaporator is sucked away by the compressor, so that the refrigerant undergoes four processes of compression, condensation, throttling, and evaporation in the system, completing a loop.
