Shandong Leader Machinery Co.,ltd. is use of reverse Carnot principle .With free air to absorb heat and transfer it to the drying chamber, Heat Pump Dryer 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 Hot selling China made air to air heat pump for fruit and vegetable other devices constitute a refrigerant cycle system. Shandong Leader Machinery Co.,ltd. 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 ℃), 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,Shandong Leader Machinery Co.,ltd. liquid absorbs heat quickly evaporates once again transformed into a gaseous state, while the temperature dropped to minus 20 ℃ --30 ℃, then the air around the heat sink will continuously transferring heat to the refrigerant. Heat Pump Dryer 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.
What is the heat pump dryer?
The air to air heat pump is finned evaporator, compressor, fin condenser (machine) and expansion valve of four parts, by making the working medium continuously complete evaporation (absorb heat from the outdoor environment) to compression, condensation (gives off heat drying room) indoors to throttle, thermodynamic cycle process of evaporation, again to the external environment at low temperature in the heat transfer to the drying room, 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℃), it enters the release of the high-temperature heat 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 can fall to - 20 ℃~ 30 ℃, then the air surrounding the heat absorber will continue to transfer heat to the refrigerant.
How does it work?
This drying machine use of heat pump evaporator absorbs heat from the outside air.or recycling of exhaust gas residual heat in the process of drying.Through the work of compressor, the energy transport (transfer) to drying box, drying box of hot air after repeated cyclic heating, absorb the moisture in the material, its cooling humidification, through hot air platoon is wet or the process of condensation, water take the moisture out of the material, and finally realizes the continuous drying of materials.
What are the advantages of heat pump fruit dryer?
1.Closed cycle drying, which can realize low temperature air drying quality is good.
3.Temperature humidity control is convenient.
4.The useful composition of volatile recycled material.
5. Environmentally friendly.
7.The application of the heat pump dryers materials widely.
Heat pump dryer running cost just as 40% of oil dryer, 50% of coal burning boiler, 30% of electric boiler.Shandong Leader Machinery Co.,ltd. Heat pump dehumidification drying method of the closed cycle, saving costs; no exhaust waste heat emissions, no noise pollution, environmental protection; Accordinary heat pump dehumidification drying energy saving over 30%;Shandong Leader Machinery Co.,ltd. median and low temperature drying method(15-50°C/60°C/80°C),similar nature drying.Hot selling China made air to air heat pump for fruit and vegetable 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;Shandong Leader Machinery Co.,ltd. adopt closed type circulating heating or cooling drying,suitable for inflammable and explosive materials, poisonous material,Pungent odor of materials,easily oxidized material etc;
