PVC mixer is composed of filter, sub filter, heater, silencer, bag catcher, induced draft fan and other components. Its working principle is: after being heated and purified, the air is introduced from the bottom by the induced draft fan, passes through the mesh plate of the hopper, and then passes through the workroom. Fluidization is formed under the action of mixing and negative pressure. After rapid evaporation, the water is taken away with the exhaust, and the materials are dried quickly. Main features of PVC high-speed mixer: The drying speed is fast. The drying time of each batch of materials is generally 20-30 minutes, and the temperature is uniform; Automatic feeding and discharging, convenient, rapid and thorough, low labor intensity; The hopper is equipped with an agitator to avoid the agglomeration of wet materials and the formation of ditches, and the hopper is dry without dead corners; Closed negative pressure operation, no dust flying, the gas is filtered and meets the requirements of GMP specification. PVC mixer is widely used in the drying of wet granules, powder, block and sticky block granular materials in food, medicine and other industries.
