Product Description
The energy saving heat pump dryer machine is using inverse Carnot cycle principle and driven by a small amount of electric energy.
1) The refrigerant (Freon) is pressurized by the compressor to become a high temperature and high pressure gas (temperature up to 100ºC) before it enters the heat exchanger (condenser);
2) The refrigerant gas is condensed and liquefied in the condenser to release high temperature heat energy,which will be transferred into the drying chamber by circulating fan to heat the air there.
3) The water in the materials are vaporized through the form of hot air, and the evaporated water steam is discharged away by the dehumidification system to achieve the purpose of drying the materials in the drying chamber.
4) After condensation and heat release,the refrigerant is changed into a low temperature and low pressure liquid through the expansion valve.
5) The liquid refrigerant will continuously absorb the low heat energy of the surrounding air and quickly evaporate into a gas state when it enters the evaporator due to the sudden reduction of the pressure;
6) The refrigerant that absorbs a certain amount of energy flows back to the compressor and the next cycle begins. In this way, the refrigerant continuously circulates the heat energy in the air to the drying chamber to heat the air.

Advantages of Heat Pump Fruits Dehydrator
1) PLC and touch screen fully automatic control mode;The operation is automatically completed by a microcomputer,which can be controlled remotely.
2) By using the proprietary technology of regenerative circulation heat pump dehumidification method, our dryers can save operating cost and save more than 50% energy compared with traditional drying mode.
3) The integrated design of the indoor and outdoor can preheat the fresh air; It can also reduce the impact on the dyring material when the fresh air enters the drying chamber on the materials.
4) Dedicated compressor and thermal expansion valve throttling technology to ensure the stability of various working conditions. 5) The dryer has a comprehensive protection function (high pressure,low pressure,exhaust,etc.) fault protection function to ensure the safe operation of the equipment.
6) Drying materials are not affected by the external environment temperature,and the wide temperature range makes it easier to use in winter or in cold areas.
7) It adopts closed-type condensation and dehumidification technology for drying,which can collect condensed water and dry materials with volatile components that have recycling value and dissolve in water.
8) The dryers adopt cold-air dehumidification and hot-air drying methods,which is widely used for drying various fruits,vegetables,meat,seafood,nuts,leaves,agricultural products,etc.
