Main parts of Freeze Dry Machine II
Condenser, Secondary Condenser (Precooling Regenerator)
With regard to the Freeze Dry Machine, the function of the condenser is to cool the high-pressure, superheated refrigerant vapor discharged from the refrigerant compressor into a liquid refrigerant, so that the refrigeration process can be continuously performed. The heat discharged from the condenser includes the heat that the refrigerant draws from the evaporator and the heat that is converted by the compression work. Therefore, the load of the condenser is larger than that of the evaporator. The condenser in the dryer is divided into an air-cooled and a water-cooled condenser.
The secondary condenser (precooling regenerator) is the same as the heat exchange function in the machine. The difference between the two is that the heat exchanger is mainly the heat exchange of high temperature and low temperature compressed air, and the secondary condensation mainly uses low temperature compressed air and the high-pressure part of the refrigeration system is cooled to achieve sufficient cooling of the refrigerant, to improve the cooling efficiency of the machine, and avoiding high-voltage tripping or machine failure caused by poor heat dissipation of the machine condenser.
Cyclone Separator (Gas Water Separator)
The cyclone separator of Freeze Dry Machine is also an inertial separator and is used more for gas-solid separation. After the compressed air enters the separator along the tangential direction of the tube wall, the rotation is generated therein, and the water droplets mixed in the gas also rotate together to generate centrifugal force. The centrifugal force generated by the large-sized water droplets is large, and the large water droplets move to the outer wall under the centrifugal force. When it hits the outer wall (also the baffle), it accumulates and grows up and separates from the gas.
