      具有結構簡單操作方便，使用周期長，性能穩定可靠，蒸汽耗暈小，適用性能強，產品質量好，特別適用于不耐高溫、易燃、調溫下易氧化的膏狀物料的干燥，該機經用戶長期使用證明是一良好的干燥設備。原理：被干燥物料從殼體上方正中間加入，在不斷正反轉動的耙齒的攪伴下，物料軸向來回走動，與殼體內壁接觸的表面不斷新，受到蒸汽的間接加熱，耙齒的均勻攪拌，粉碎棒的粉碎，使物料表面水分有利的排出，氣化的水分經干式除塵器、濕式除塵器、冷凝器，從真空泵出口處放空。
It enjoys advantages as easy & convenient operation, long life circle, stable & reliable performance, low steam consumption, strong adaptability and good quality which are especially applicable for drying paste materials which cannot resist high temperature, flammable and is easy to be oxidized under temperature adjusting. It is proved to be a good drying device after long-time use by the users. The principles are: add the materials to be dried from middle of upper part of the shell body. The materials move in axial direction back and forth under positive and negative rotation of the rake (stirring). The surface which contacts with inner wall of the shell keeps renewing. Under indirect heating of the steam, even stirring by the rake and crushing by the crushing bar, it is easier for water on material surface to be discharged. The gasified water is emptied at outlet of vacuum pump by dry-type collector, wet type collector and condenser.
