Drying Technology
Dehumidification heat pump = combination of dehumidification (drying) + heat pump (energy recovery)，which is a device that is to make humid air cool and dehumidify by refrigeration system while recovering moisture through heat pump principle to condense latent heat to heat the air. Heat source = The phase change of water vapor in the air releases condensation heat. Closed drying at low temperature (7-75℃), and energy recycling during the drying process.
Air flow: heating by hot air in the drying room, the material absorbs heat and water vaporizes, the air absorbs moisture into hot and humid air → enters the evaporator, the air is cooled to below the dew point temperature, the water vapor condenses and releases the latent heat of condensation → enters the air condenser to absorb the refrigerant and release it during condensation Heat heating air → main fan → drying room.
Adopt closed cycle dehumidification and drying method, no exhaust gas and waste heat emission. Compared with the traditional open drying mode, it can save energy by more than 50%.
Not affected by external ambient temperature (low temperature in winter), humidity (Humid in summer)impact, meeting theannual use requirements of various regions
Adopting closed cycle drying method, suitable for drying in an inert environment, suitable for drying materials that are flammable,explosive, harmful, toxic, pungent, easy to oxidize and need to recycle volatile components such as aromas
PLC，Intelligent control mode of single-chip microcomputertouch screen, stable function, easy to operate; It can be setted fordifferent drying curve and the needs of different types whenprogrammable control mode adopted
No pollutant discharge, no noise pollution, meeting environmental protection requirement
Medium and low temperature drying method, excellent drying quality and high product grade
Closed drying, not affected by weather and area, air supply can reach 90°C wind temperature
Good hygiene during drying.
Refrigerant process: The low-pressure refrigerant liquid is vaporized by the evaporator to absorb the air and release heat to vaporize into low-pressure superheated gas → enter the compressor → low-pressure superheated refrigerant gas passes through the compressor is entropic compression to work to high-grade, high-temperature and high-pressure gas → enters the wind condenser to release the latent heat of condensation into a high pressure liquid→expansion valve, after decompression to low temperature and low pressure liquid→evaporator.
