Product introduction:
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.
Working Principle
Materials are uniformly put on the mesh belt by the feeder. The mesh belt dryer generally use 12-60 mesh stainless steel wire net and it is drawn and moved inside the dryer by a transmission device. The dryer is composed of several units. For each unit, the hot air is circulated separately. Some exhausted gas is discharged by a special moisture elimination blower. The waste gas is controlled through an adjustment valve. And the hot air passes through the mesh belt covered with the material from the top to the bottom or from the bottom to the top and this will complete the heat and materials transfer process. In this process, the hot air will bring the material water away. The mesh belt dryer can be adjusted freely as customer's demand.
