Working principle of freeze dryer

Tuesday 02nd August 2016


Wet high temperature compressed air flows into the pre cooler (high temperature type special) radiating into the cold air heat exchanger and from the evaporator heat exchange, make into the evaporator of the compressed air temperature drop.  

Heat after the compressed air flows into the evaporator through the evaporator for heat function and the refrigerant heat exchange, the compressed air in the heat is carried away by the refrigerant, compressed air is cooled rapidly, moisture moisture in the air to saturation temperature rapid condensation, condensation water agglomerated after the formation of droplets, through a unique gas water separator for high-speed rotation, water due to the centrifugal force and the role of air separation, after the separation of water from the automatic drain valve discharge. After cooling the air pressure dew point can be up to 2.  

Cooling cold air flows through the air heat exchange with the entrance to the hot and humid heat air for heat exchange, the heat exchange of the cold air due to absorption of the air inlet of the heat elevates the temperature, while the compressed air through the refrigeration system of the second condenser (peer unique design) and temperature of the refrigerant again in the heat exchange outlet temperature sufficient heating, to ensure that the air outlet pipe without dewing. At the same time, make full use of the cold source of the outlet air, to ensure that the cooling system of the cooling system, to ensure the quality of the air quality of the machine.
