工作原理：

在密閉的夾層中通入熱能源（如熱水，低壓蒸汽或?qū)嵊停?，熱量?jīng)內(nèi)殼傳給被干燥物料。

在動力驅(qū)動下，罐體作緩慢旋轉(zhuǎn)，罐內(nèi)物料不斷地混合，從而達到強化干燥的目的。

物料處于真空狀態(tài)，蒸汽壓下降使物料表面的水份（溶劑）達到飽和狀態(tài)而蒸發(fā)了，并由真空泵及時排出回收。物料內(nèi)部的水份（溶劑 ）不斷地向表面滲透、蒸發(fā)、排出，三個過程不斷進行，物料在很短時間內(nèi)達到干燥目的。

Let heat source （for example, low pressure steam or thermal oil） pass through the sealed jacket. The heat will be transmitted to raw material to be dried through inner shell;

Under driving of power, the tank is rotated slowly and the raw material inside it is mixed continuously. The purpose of reinforced drying can be realized;

The raw material is under vacuum. The drop of steam pressure makes the moisture （solvent） at the surface of raw material become saturation and will evaporate. The solvent will be discharged through vacuum pump and recovered in time. The inner moisture （solvent） of raw material will infiltrate, evaporate and discharge continuously. The three processes are carried out unceasingly and the purpose of drying can be realized within a short time

性能特點：

油加熱時，采用自動恒溫控制，可以干燥生化制品和礦物原料，溫度可在20～160℃之間。

熱效率高，比一般烘箱提高2倍以上。

間接加熱，物料不會被污染，符合"GMP" 要求。設備維修操作簡便，易清洗。

*的工藝安置示范：溶劑回收工藝安置

When oil is used to heat, use automatic constant temperature control. It can be used for drying biology products and mine. Its temperature of operation can be adjusted form 20-160 ℃ .

Compared to ordinal dryer, its heat efficiency will be 2 times higher.

The heat is indirect. So the raw material can not be polluted. It is in conformity with the requirement of GMP. It is easy in washing and maintenance.

適用化工、制藥、食品等行業(yè)的粉狀、粒狀及纖維的濃縮、混合、干燥及需低溫干燥的物料（如生化制品等），更適用于易氧化、易揮發(fā)、熱敏性、強烈刺激、有毒性物料和不允許破壞結(jié)晶體的物料的干燥。

It is suitable for the raw materials that need to concentrate, mixed and dried at low temperature （for example, biochemistry） products in chemical, pharmaceutical and foodstuff industries. Particularly it is suitable for the raw materials that are easy to be oxidized, volatilized and have night heat sensitivity and is toxic and not permitted to destroy its crystal in drying process
