Hot air circulating drying machine belongs to high temperature heat pump unit. Its working principle is: the working fluid of the heat pump is compressed by the compressor, becomes high temperature and high pressure gas, enters the condenser, condenses and liquefies the heat, and is used for air heating in the drying room. The moisture in the material is vaporized and evaporated by the form of hot air, and the evaporated water vapor is discharged by the moisture discharge system, thereby achieving the purpose of drying the drying material.
1. New design idea--Three times waste heat recovery;
2. Adopt heat regenerators to dehumidify;
3. Adopt touch screen controllers and dry/wet bulb to control temperature and humidity, operation drying machine easily and more accurate;
4. adopt duct-type drying method, it with shorter drying time and well-distributed hot air, drying time shorter 30% than old models;
5. during drying, the material does not craze,does not distortions, nondiscolouring, never degenerate, non-oxidize, drying completely, with good Rehydration, keep nutrient content.
