Heat pump device consists of compressor, electronic expansion valve, drying filter, four-way valve, evaporator, casing condenser, fan and other major components, it adopts inverse Carnot principle, the compressor from the evaporator inhalation of low temperature and low pressure air refrigerant, by the work of the refrigerant compressed into high temperature and high pressure air, high temperature and high pressure air into the condenser exchange heat with air, condensed into a cryogenic liquid in the condenser and release a lot of heat, the material absorbs its release of energy through the hot air circulation strong row of its moisture to achieve the purpose of drying materials.
- Low temperature, closed loop drying, guarantee the quality of dried.
The drying temperature is 40-75 degree, avoid changing the color of food, and closed loop drying system, and avoid external contamination.
- Saving cost and high efficiency
The majority of heat of dryer are sensible heat and latent heat from reclaimed air of drying room, only need little electricity to work compressor, so, the SMER(dehumidification capacity by using the unit energy) is 1.0-4.0KG/Kwh, but traditional hot air dryer is 0.2-0.6 KG/Kwh.
- Easy regulation of temperature and humidity
We can guarantee the quality and appearance of dried material by adjusting the evaporating temperature and condensing temperature of the device.
- Environmentally Friendly
No material dust and abnormal flavor released to environment, no pollutant of device.
