At present, agriculture, food, chemical industry, ceramics, medicine, mineral processing, pulp and paper, wood processing and other industries, all the production process almost all use drying, drying material quality depends on whether a good control of constant temperature.
Heat pump drying technology is a mild, close to natural drying method, more suitable for most agricultural products, medicinal materials and other heat-sensitive materials drying.
The principle of heat pump dryer is the use of reverse carnot principle of gas compressor pressurized, become (temperature up to 100 ℃), high temperature and high pressure gas entering the indoor side of heat exchanger (condenser), refrigerant condensing liquid heat release of the high-temperature heating drying room air.
The materials in the drying room will vaporize and evaporate the moisture in the materials in the form of hot air, and the evaporated water vapor will be discharged by the dehumidification system to achieve the purpose of drying the materials.
The heat pump dryer only needs to consume the electrical energy which the compressor USES when the work, may obtain more energy from the air, the energy efficiency ratio is as high as 400%, is more energy saving than other drying methods.
