Descriptions：   
    SZG Series Conical Vacuum Dryer is a new generation drying device developed by our factory on the basis of combining the technology of similar equipment. It has two connecting ways, i.e. belt or chain. Therefore it is stable in operation. The special design guarantees two shafts realize good concentricity. Heat medium and vacuum system all adapt reliable rotating connector with the technology from USA. On this basis, we also developed SZG-A. It can carry out steeples speed change and constant temperature control.
    As a specialized factory in drying industry, we supply hundred sets to the customers every year. As for working medium, it may be thermal oil or steam or hot water. For drying the adhesive raw material, we have designed specially a stirring plate buffer for you.
Principle：
● Let heat source (for example, low pressure steam or thermal conduct 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 e realizd;
● The raw material exists is under vacuum. The drop of  team  pressure makes the moisture (solvent) at the surface of  raw material become saturation and will  evaporate. The solvent will be discharged through vacuum  pump an 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.
Features：
● 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.
Applications：
    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.

Note： on dry volume has great change before and after the material, its filling coefficient can be increased or decreased suitably.
