2.how heat pump dryers work

High temperature heat pump dryer is to use the inverse carnot principle, absorb free heat in the air and transfer it to the drying warehouse, to achieve the drying room temperature increase, with the corresponding dehumidification and drainage equipment to achieve the drying of materials.Heat pump dryer by compressor - heat exchanger (internal machine) - throttling device - heat receiver (external machine) - compressor and other devices constitute a refrigerant circulation system.under the action of refrigerant in the compressor circulating in the system, it made within the compressor gas booster heating process (temperature up to 100 ℃), it enters the release of the high-temperature heat drying room air, while being cooled and translated into flow liquid when it runs to the outside machine, liquid evaporation heat quickly again into gas, the temperature dropped to minus 30 ℃, 20 ℃, the air surrounding the heat absorber will continue to transfer heat to the refrigerant.The continuous circulation of refrigerant realizes the transfer of heat from the air to the drying room to heat the air temperature in the room to achieve the purpose of drying materials.5. Waste heat recovery system: the drying system has a total of 3 waste heat recovery lines, which can minimize the loss of heat and achieve high efficiency.

6. Dryer Features:

Compared with the traditional drying method, the hot air drying equipment has the following features
1. Use electronic temperature controller or digital display temperature controller to control temperature, and the temperature is accurate and reliable.
2, using tempered glass observation door, safe and reliable, easy to observe.
3, high temperature silicone rubber sealing strip, good sealing and thermal insulation performance, good anti-aging performance.

7.Composition of heat pump drying system

 

1. Main machine (heating system): absorbs free heat from the air with little electric energy input, and USES it to dry materials.

2, drying room: used for placing materials, and insulation to avoid heat loss.

3. Circulating air system: bring heat to every corner of the drying room to raise the temperature of the drying room, and take away moisture from the materials.

4. Moisture drainage system (drying system): the purpose of drying is to discharge the moisture with high humidity in the drying room.

5. Waste heat recovery system: the drying system has a total of 3 waste heat recovery lines, which can minimize the loss of heat and achieve high efficiency.

6. Drainage system: condensate water is discharged to the outdoor to avoid increasing the humidity of indoor air.
