Hot air enters into stirring and crushing and drying chamber from the botton of drier with suitable atomizing speed. It exerts strong shearing, blowing, floating and rotating effect to raw material. Therelore raw material is granulated through centrifuge, sheafing, impacting and friction effect. It strengthens the process of heat exchange. At the bottom of drier, the large and damp granule is crushed under the action of stirrer and the granule that is small in particle and contain less moisture will lift accompanied with revolving air stream. During the period of lift, it is dried further. Because two phases gas and solid of flow in rotating and the inertia of solid phase is more than that of gas and the relative velocity between solid and gas phases is large, so it strengthens the process of heat exchange. Therefore the machine has strong drying capacity.

 

    由于物料受到离心、剪切、碰撞、摩擦而被微粒化，呈高度分散状态及固气两相间的相对速度较大，强化了传质传热，使该机生产强度高。
    干燥气体进入干燥机底部，产生强烈的旋转气流，对器壁上物料产生强烈的冲刷带出作用，消除粘壁现象。
    在干燥机底部高温区，热敏性物料不与热表面直接接触，并装有特殊装置，解决了热敏性物料的焦化变色问题。
    由于干燥室内周向气速高，物料停留时间短，达到高效、快速、小设备、大生产。
干燥室上部加装陶析环及旋流片可以控制出口物料的粒度及湿度，以达到不同物料的终水份粒度的要求。
