DRYTECH(GUANGZHOU) TECHNOLOGY CO.,LTD is a professional manufacturer that independent develop and produce "DRYTECH" series heat pump dryers, dehumidifier etc. The factory cover more than 8000 square meters, there are 50 employees, more than 10 technical research and development personnel. Have first-class production workshop and production equipment, advanced simulation test facilities climate laboratory, is one of the largest production base of heat pump in China. DRYTECH brand series heat pump dryer is based on many years' experience and introduced advanced manufacturing technology in heating/cooling system equipment from Europe, United States and other developed countries, without any pollution, and very low energy consumption, environmental protection, it is one kinds of saving energy products. The heat pump dryer is the Carnot thermal reversed cycle, which transfers the bigger amount of heat to the higher temperature storage room(drying chamber) from the lower temperature thermal source(ambient temperature) by supplying a certain amount of mechanical work. In South East asia,South Asia and Africa weather condition, the typical energy efficiency of the heat pump dryer for biomaterial drying application is about 400%, which mean four units of the heat will be obtained for drying purpose by just consuming one unit of energy,in other words,COP(Coefficient of Performance) reach to 4.0. The energy efficient and climate friendly HPD(Heat Pump Dryer) used as the sample for marketing of the technology in the agricultural and energy sector. It can be use in drying fish,Seaweed and seatangle(marine food products),Meat(pork,beef), Drying fruits(plums,grapes,mango,apple),vegetable, food manufactures and wood processing companies.
