Heat pump dryer technology and its application

The heat pump drying unit is applicable to the drying of hotel bedding, seafood, vegetable dehydration, AD black tremella, melon seeds, peanuts, fruits and vegetables, meat products, casings, tobacco, leather, mushrooms, wolfberry, dried fruit, mosquito repellent incense, tribute incense, cloth, clothing, grain, hanging noodles, Rolls of dried bean milk creams, fertilizer, medicine, Chinese medicinal materials, paper products, wood, seeds, sludge, gypsum, hardware products, metallurgical products, mining by-products, chemical products, FGD gypsum, clay, grass, flue-cured tobacco, powdered coal, slime, lignite, etc. In terms of industrial hot water, it can also meet the constant temperature of electroplating solution in electroplating plants, the heating and insulation of high-temperature hot water in slaughterhouses, the supply of high-temperature hot water in star rated hotels, and the demand for high-temperature hot water in industrial enterprises.

PHNIX high-temperature drying heat pump unit adopts high-temperature digital vortex technology, with an accurate temperature within+0.2 ℃; PHNIX high-temperature drying heat pump uses green and environmentally friendly R134A refrigerant, with a maximum drying temperature of 80 ℃ and energy consumption only 1/5-1/4 of traditional drying methods. PHNIX high-temperature drying heat pump is now widely used in the drying of materials such as tobacco, food, medicinal herbs, wood, building materials, cardboard, etc. It has the characteristics of green energy saving, good drying quality, and high degree of automation. It is an ideal substitute for traditional drying methods, especially suitable for box drying of small and medium-sized models.

Heat pump food drying equipment is a commonly used food dryer, which circulates forced hot air heated by electric heating tubes or steam heat exchangers inside the box, enhances heat transfer, improves water evaporation rate, and shortens drying time. The entire box adopts a fully enclosed structure, with hot air circulating inside the box to reasonably discharge humid and hot air and replenish fresh air. The heat pump food drying equipment is equipped with an automatic temperature control system, which has precise temperature control. There is an adjustable air distribution plate inside the box, ensuring even temperature inside. Adopting a low-noise and energy-saving built-in circulating fan, the operation is balanced, greatly reducing the noise and heat loss of the equipment. The air inlet is equipped with an air filter and comes standard with a dehumidification device.

The heat pump dryer consists of a heat pump system (evaporator, compressor, condenser, throttle valve, etc.) and an air system (drying room, fan, electric heater, etc.).

Therefore, the heat pump drying cycle includes two cycles: (1) the steam compression cycle of the refrigerant. (2) The circulation of dry air.

Air can dry materials well, is environmentally friendly, has a long lifespan, and dries materials thoroughly.

The deep processing production of agricultural products and the energy consumption during the production process of heat pump dryers are receiving increasing attention. The processing of agricultural products will develop towards the direction of green, pollution-free, hygiene, and safety. The utilization of green energy in the production process of agricultural products, especially in the drying process, will become increasingly widespread.
