工作原理: 空氣通過加熱轉化為熱空氣,進入裝置在乾燥室頂部的熱風分配器,然後均勻的進入乾燥室,並呈現 螺旋狀轉動,同時將料液送至裝置在乾燥室頂部的離心霧化器, 使料液霧化成極小的霧化液滴,料液和熱空氣並流接觸,水份迅速蒸發,在極短的時 間內乾燥為成品。 成品經乾燥乾塔底部和旋風分離器排出, 廢氣由風機抽出排空。 主要特點 A、乾燥速度快,料液經霧化後,表麵積大大增加,在熱風氣流中瞬間就可蒸發65%- 98% 的水份,完成乾燥時間僅需5-15秒。 特別適用於熱敏性物料的乾燥。 B、所得產品粒度均勻,流動性、速溶性良好,產品純度高,質量好; C、操作簡單穩定,調節控制方便,容易實現自動化作業。 D、生產過程簡化,操作環境衛生條件優越, 能避免乾燥過程中的粉塵飛揚。
LPG series high speed centrifugal spray dryer
2.Principles
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 mistliquid beads.Through the very short time of contacting the heatair,the materials can be dried into the finished products . The finished products will separator .The waste gas will be discharged from blower.
3.Features
◆ 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, disso -lving 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.
