原理 Principle
空氣經過過濾和加熱,進入干燥器頂部空氣分配器,熱空氣呈螺旋狀均勻地進入干燥室。料液經塔體頂部的高速離心霧化器,(旋轉)噴霧成極細微的霧狀液珠,與熱空氣并流接觸,在極短的時間內可干燥為成品。成品連續地由干燥塔底部和旋風分離器中輸出,廢氣由風機排空。
After filtering and heating, the air enters into the air distributor at the top of the drier. The hot air enters into the drying chamber in the spiral from and uniformly.By passing through the high-speed centrifugal spray at the top of the tower, the material liquid will rotate and be sprayed into the extremely fine mist liquid beads.Through the very short time of contacting the heat air,the materials can be dried into the finished products. The finished products will separator. The waste gas will be discharged from blower.

特點 Featrures
◎ 干燥速度快,料液經霧化后,表面積大大增加,在熱風氣流中,瞬間就可蒸發95%-98%的水份,完成干燥時間僅需數秒鐘,特別適用于熱敏性物料的干燥。
◎ 產品具有良好的均勻度、流動性和溶解性、產品純度高、質量好。
◎ 生產過程簡化,操作控制方便。對于濕含量40-60%(特殊物料可達90%)的液體能一次干燥成粉粒產品,干燥后不需粉碎和篩選,減少生產工序 ,提高產品純度 。對產品粒徑、松密度、水份,在一定范圍內可通過改變操作條件進行調整,控制和管理都很方便。
◎ At a high speed of drying, after the spraying of the liquid material , the surface area of the material will be increased greatly. In the hot-air flow, 95%-98%of water can be evaporated at a moment. The time of completing the drying needs only several seconds.
◎ This id especially suitable for drying the heat sensitive materials. Its final products own the good uniformity, mobility, dissolving capacity. And the final products are high in their purity and good in their quality.
◎ The production procedures are simple and the operation and control are easy. The liquid with the moisture contents 40-60%(for special materials, The contents may reach 90%).can e dried into the powder or particle products once a time. After the drying, there is no need for smashing and sorting, so as to reduce the operation procedures in the production and to enhance the product purity. The product particle diameters, looseness and water contents can be adjusted through changing the operation condition in a certain scope. It is very convenient to carry out the control and management.
