Heat pump dryer is use of reverse Carnot principle .With free air to absorb heat and transfer it to the drying chamber, drying room temperature to achieve improved, with the appropriate humidity and dehumidification equipment to achieve dry materials. heat pump dryer Compressor - heat exchangers - Chokes - heat sink (outside the machine) - Compressor and other devices constitute a refrigerant cycle system. Under the action of the compressor in the refrigerant circulating in the system flow, it is done in the gaseous booster compressor heating process (temperature up to 100 ºC), releasing it into the machine dry in room temperature air heated by the heat, while they have been and converted to liquid cooling flow, when it runs out machines, liquid absorbs heat quickly evaporates once again transformed into a gaseous state, while the temperature dropped to minus 20 ºC --30 ºC, then the air around the heat sink will continuously transferring heat to the refrigerant. Refrigerant continuous cycle to achieve the heat in the air transport to the drying room heating room air temperature to achieve the purpose of dry material.

1.Heat pump dryer running cost just as 40% of oil dryer, 50% of coal burning boiler, 30% of electric boiler . Heat pump dehumidification drying method of the closed cycle, saving costs; no exhaust waste heat emissions, no noise pollution, environmental protection;
2.Using our patented technology: circulating heating & dehumidification, broaden the application of a dehumidifier in industrial drying, drying performance better than ordinary heat pump dehumidification drying energy saving over 30%; 3.median and low temperature drying method(15-50°C/60°C/80°C),similar nature drying.
4.Drying process material no deformation, no cracking, no-discoloration , no deterioration, and no oxidation, thorough drying, after drying and rehydration, less loss of nutrients, the long storage period, more than any conventional drying equipment to more effectively protect the color of the dried material, smell, taste, individual form and active ingredients;5.adopt closed type circulating heating or cooling drying , suitable for inflammable and explosive materials, poisonous material , Pungent odor of materials , easily oxidized material etc ;
6.installation and operation easily , just need connecting with drying chamber by wind pipe;
