Heat pump device consists of compressor, electronic expansion valve, dry filter, four-way valve, evaporator, casing condenser, fan and other major components, it adopts inverse Carnot principle, the compressor from the evaporator inhalation of low temperature and low pressure air Refrigerant, through the work of the refrigerant compressed into high temperature and high pressure air, high temperature and high pressure air into the condenser and air exchange heat, condensed into a cryogenic liquid in the condenser and release a lot of heat, the material absorbs its release of energy through the hot air circulation strong row of its moisture to achieve the purpose of drying materials.
The condensed high temperature and low pressure liquid is throttled and reduced by the expansion valve, and the heat of the surrounding air is absorbed by the action of the fan in the evaporator to volatilize into the low pressure air and is compressed into the compressor, so that it is circulated continuously and dry materials continuously.
1. The mesh belt has good gas permeability, and the product drying cycle can be adjusted arbitrarily.
2. The equipment runs smoothly and the materials are not easily damaged.
3. Large drying area and high strength.
4. Hot air circulation structure, uniform temperature and reduced energy consumption.
5. According to customer needs, it can be divided into several units, each unit can control the loop separately.
6. There are various heat source selections, such as electric heating, heat transfer oil heating, hot air heating, etc.
