工作原理 WORKING PRINCIPLE:
热空气由入口管以适宜的喷动速度从干燥机底部进入搅拌粉碎干燥室,对物料产生强烈的剪切、吹浮、旋转作用,于是物料受到离心、剪切、碰撞、摩擦而被微粒化,强化了传质传热。在干燥机底部,较大较湿的颗粒团在搅拌器的作用下被机械破碎,湿含量较低,颗粒度较小的颗粒被旋转气流夹带上升,在上升过程中进一步干燥。由于气固两相作旋转流动,固相惯性大于气相,固气两相间的相对速度较大,强化两相间的传质传热,所以该机生产强度高。
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.
产品特点 PRODUCT FEATURES:
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。 Because the raw material particulate exists in high dispersing state caused by centrifuge, shearing, impacting and rubbing effect. Moreover the relative velocity between solid and gas phases is high, so it strengthens the process of heat exchange. Therefore the machine has strong drying capacity.
Dry gas enters into the bottom of drier and produces strong rotating air stream that exerts strong rushing effect to raw material on the wall, therefore the phenomenon of stricking on the wall is removed.
At the bottom of drier, where is high temperature area, heatsensitivity raw material can not contact with heat surface directly, therefore it solves the carbonization and color charge problems of heat sensitivity raw material.
Because gas speed at circle inside the drying chamber is high and the staying time of raw material is short, high efficiency and quick speed can be realized. It is possible for small equipment to carry out large-scale production.
There are rotation flow pieces and elutriation ring inside the drying charnber. It is used to control the moisture and granule of raw material to the needed level.
