What is the role of the freeze dryer in the nitrogen machine series?

Refrigerated dryer ---- The refrigerated dryer in the whole equipment of the Trojan nitrogen machine plays a key role, so what is its main role? The following will be explained to you in detail: Frozen dryers use physical principles, under the compressed air refrigeration dew point, the air dryer air separation. The freezing temperature point of limited water, in theory, its dew point temperature can be close to 0 degrees, in practice, the dew point temperature of the freeze dryer is generally about 5 degrees. The humid and high temperature compressed air flows into the cooler (special for high temperature type), radiates the heat transfer to the heat exchanger, and the cold air is discharged from the evaporator into the evaporator, and the temperature of the compressed air is reduced.

After heat transfer, the compressed air flows into the heat transfer function of the evaporator and the refrigerant heat exchange of the evaporator, the heat in the compressed air is taken away by the refrigerant, the compressed air is quickly cooled, and the moisture saturation temperature in the air is quickly condensed. After the formation of the condensed water droplets, the water function is separated from the air by centrifugal force through high-speed rotation. After the water is discharged and separated from the blowdown valve. The pressure dew point of cold air is at least 2 ° C. The cooled cold air flows through the air heat exchange by the heat exchanger in the hot and humid hot air inlet, due to the increase in the inlet air heat absorption of the cold air temperature heat exchange, while the compressed air through the condenser refrigeration system of the two (unique design) and the refrigerant heat exchange temperature outlet temperature is fully heated to ensure that the outlet air pipe does not condensation. At the same time, make full use of the air outlet of the cold source to ensure the condensation effect of the refrigeration system and ensure the quality of the outlet air.

The following is our company's freeze-type dryer, the picture is for reference only, the user needs the specific model specifications of the freeze-type dryer can call for consultation.
