所謂振動流化床就是在普通流化床的基礎上施加振動而成。振動流化床干燥機是由振動電機產生激振力使機器振動,被處理物料就是在這給定方向的激振力的作用下跳躍前進,同時流化床底部輸入的熱風使物料處于流化狀態。物料與熱風充分接觸,從而達到理想的干燥效果。物料從料口進入,振槽上的物料與振槽下部通入的熱風正交接觸傳熱,濕空氣由引風引出,干物料由排料口排出。
Principle the called vibration fluidized bed is made on the basis of common fluidized bed onto which vibration is added. The exciting force produced by vibration motor in the vibration fluidized bed drier makes the machine vibrate, the processed material leaps forward under the effect of exciting force in the given direction meanwhile, the hot wind input from bottom of fluidized bed makes the material be in a fluidized state. The material amply contacts the hot wind, so as to attain the ideal drying effect. Primary grains contacts hot wind thoroughly, which helps to get the ideal drying effect. Grains coming into the vibrating channel from the feed opening, blends with the hot wind coming from under the channel. The wet is led out by the induced air, and the dry grains are dischaged by the gate
