Heat pump dryer,infact is use of the heat pump technology applying into drying. A Heat pump dryer is the use of reverse carnot principle, absorbing outdoor hot air and transferring them into the drying room, to realize the temperature of drying room, cooperate with relevant equipment to realize the material drying.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 temperature.
1.the materials will put on the belt and materials do not moved on the belt ,so It belongs to static dryer. So the shape of raw material to be dried should not be destroyed.
2.The equipment has no dead corner so it is easy to clean fully and there is no cross pollution;
3. Machine materials : AISISUS304 , AISISUS316L, and other material .
4. For the electrical component , we mainly use international brand such as ABB ,Siemens or Schneider.
5. Control system has more choices, such as push button , HMI+PLC and so on.
6. Fan speed is controlled by VFD (Optional), and it can adjust the air volume .
