產(chǎn)品簡介

工作原理 WORKING PRINCIPLE：
熱空氣由入口管以適宜的噴動速度從干燥機底部進入攪拌粉碎干燥室，對物料產(chǎn)生強烈的剪切、吹浮、旋轉(zhuǎn)作用，于是物料受到離心、剪切、碰撞、摩擦而被微?；?，強化了傳質(zhì)傳熱。在干燥機底部，較大較濕的顆粒團在攪拌器的作用下被機械破碎，濕含量較低，顆粒度較小的顆粒被旋轉(zhuǎn)氣流夾帶上升，在上升過程中進一步干燥。由于氣固兩相作旋轉(zhuǎn)流動，固相慣性大于氣相，固氣兩相間的相對速度較大，強化兩相間的傳質(zhì)傳熱，所以該機生產(chǎn)強度高。
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.
產(chǎn)品特點 PRODUCT FEATURES:
由于物料受到離心、剪切、碰撞、摩擦而被微?；?，呈高度分散狀態(tài)及固氣兩相間的相對速度較大，強化了傳質(zhì)傳熱，使該機生產(chǎn)強度高。
干燥氣體進入干燥機底部，產(chǎn)生強烈的旋轉(zhuǎn)氣流，對器壁上物料產(chǎn)生強烈的沖刷帶出作用，消除粘壁現(xiàn)象。 在干燥機底部高溫區(qū)，熱敏性物料不與熱表面直接接觸，并裝有特殊裝置，解決了熱敏性物料的焦化變色問題。 由于干燥室內(nèi)周向氣速高，物料停留時間短，達到高效、快速、小設(shè)備、大生產(chǎn)。 干燥室上部加裝陶析環(huán)及旋流片可以控制出口物料的粒度及濕度，以達到不同物料的終水份粒度的要求。 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.
