2-Flash Dryer drying machine

Principle Hot air from machine bottom with suitable atomizing speed enter into the stirring and crushing room, it process raw material by cutting, shearing, blowing, floating and rotating. Then raw material is granulated through centrifugation, shearing, impacting and friction effect. This strengthens the process of heat exchange and water evaporation. Materials enter into the dryer through the screwing feeding hole, under the powerful high speed effect of stirring, materials are distributed by the function of striking, friction, shearing and cutting, raw materials are instantly smashed and fully contact with hot air, and they are heated and dried. The dried power material will be raised with the hot air flow, small particles are discharged from the ring center and collected by cyclone separator, the rest of materials are kept by graded ring and processed by centrifugal action, throw forward to the inside wall. Then, drop to bottom, smashed and dried again. Because gas and solid are rotated together, inertia of solid is bigger than gas' and the relative speed between solid and gas is large, this strengthens the process of heating exchange. Therefore, this machine has strong drying capacity. Features 1, Drying gas enters into the bottom of machine and formed strong rotating air flow, it can wash material sticking on the inside wall, this can remove adhibited material and always keeps inside wall clean. 2, In high temperature area at the bottom of equipment, heat sensitive raw material do not need directly contact with heating surface, there is a special device which can solves heat sensitive material's carbonized and color change problems. 3, A segmenting ring and a rotational flow piece are equipped in the upper drying room in order to control granulated size and finished products moisture to satisfy required water containing rate and granulation. drying machine
