The heat pump dryer main parts including compressor, heat exchanger , choke, heat absorber - compressor unit constitute a circulation system, etc. 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 ºC), heat release it into the machine-- high temperature heating drying room air, while being cooled and translated into flow liquid when it runs to the outside machine, rapid heat evaporating liquid into a gas again, at the same time, the temperature dropped to minus 30 ºC, 20 ºC, the air surrounding the heat absorber will continue to transfer heat to the refrigerant. The refrigerant cycle is constantly realize heat from the air transport to the drying room heating the air inside the room.
1. Heat source using heat exchange furnace, outlet temperature up to 130-150℃.In order to make food, medicinal herbs, fruits, vegetables and other material to keep good shape, color and internal organization is not damaged, improve the quality of production, control the drying temperature 60℃-90℃. Heat source adopts heat exchange method, make the clean air enter into the machine, make the material avoid pollution.
2.The equipment adopts the control motor, according to the moisture content of material is different, adjust the time of material in the dryer operation, thus guarantee the drying efficiency.
3.There are setting up 8 sets observation door on the dryer machine, not only can observe the drying chamber, but also convenient cleaning equipment.
4.Wide application range, simple operation, easy to maintain.
5. This type dryer machine without foundation can be used.
1.Free repair within 1 year of guarantee on the condition of operate the machine in the right way,do not include the daily maintaining
