Heat Pump Drying Equipment/Fruit Drying Machine

1.Introduction of Heat Pump Drying Machine

A.The heat pump dryer is a kind of high-temperature heat pump drying equipment.

B.The temperature in the drying room is increased by compressing air, and a large amount of hot air is circulated in the dryer box.

C.The fresh air that is added continuously enters the box from the air inlet and then is discharged from the moisture exhaust port to increase heat transfer.

D.The effect is to gradually reduce the moisture content of the material in the box.

2.Accessories of Heat Pump Drying Machine

A.Tray: it is optional of plastic material, galvanized iron, stainless steel, wood, etc;

B.Trolley: we can customize the trolley size according to the drying box dimension, raw material.

C. Compressor: Adopt the world-famous brand Copeland top-grade flexible scroll compressor, which has functions of low wear resistance, long service life, over current protection.

D. Electronic Expansion Valve: Introducing the latest technology from Japan and the company's outstanding control system.

E. Evaporator: The use of a hydrophilic film aluminum foil does not cause oxidative detachment even after long-term use of the hydrophilic layer.

F. Touch Screen: Drying+Dehumidifing+Cooling

3.Production technology of heat pump drying machine(Take longan for example)

 

Longan(Dry fresh longan up at 60ºC within 20-25 hours)

A.Firstly, set the temperature higher so as to remove moisture quickly;

B.Secondly, reduce the temperature, keep it for several hours to make water ooze from inner part to the surface.

C.Thirdly, raise the temperature on a gradual basis.

4.Why most people choose a heat pump drying machine?

A.The procedure of material drying is huge energy-consuming. According to statistics,the energy consuming of drying accounts for 7%-15% of total national energy consumption in most developed countries, but the thermal efficiency is only 25%-50%.

B. The operating cost of the heat pump dryer is only 30% of the electric heating dryer, 40% of the fuel dryer, 60% of the coal-fired dryer, and the heat pump dryer should not consume any materials.

 

C. Heat pump drying technology has the advantages of less energy consumption, less environmental pollution, high drying quality, and a wide application range.
