The high temperature 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 leaves, leather, mushrooms, medlar, dried fruit, mosquito repellent incense, tribute incense, cloth, clothing, grain, dried noodles, Rolls of dried bean milk creams, fertilizer, medicine, Chinese medicinal materials, paper, wood, seeds, sludge, gypsum, hardware products, metallurgical products, mining by-products, chemical products, FGD gypsum, clay, grass, 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. A heat pump is essentially a device for increasing heat. The high-temperature heat pump drying unit uses the reverse Carnot principle to extract heat from the surrounding environment and transfer it to the object being heated (a higher temperature object). Its working principle is opposite to that of a refrigeration machine, both working according to the reverse Carnot cycle principle. The difference between the two is that the former increases the temperature and the latter decreases the temperature.
