The advantages   of the vacuum rake dryer of Changzhou Fengri Powder Equipment Co., Ltd . : steam is used for heating, which needs to be heated from the inside to the outside. The slow heating speed requires a lot of coal, and the microwave vacuum drying equipment uses electromagnetic wave heating , No heat transfer medium, directly heated into the object, the temperature rises quickly, the microwave energy of 1 kilowatt can heat the water at room temperature to 100 ℃ in 3-5 minutes, avoiding the above shortcomings, so the speed is fast, high efficiency, dry The period is greatly shortened and the energy consumption is reduced. Compared with the conventional drying technology, it can improve the work efficiency by more than four times.
