SZG Conical Vacuum Dryer
Descriptions
SZG Series Conical Vacuum Dryer is a new generation of drying device developed by our company on the basis of combining the technology of similar equipment. It has two connecting ways, belt or chain. Therefore it is stable in operation. The special design guarantees two shafts to realize good concentricity. Heat medium and vacuum system all adopt 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 company 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. The biggest may be 8000L.
Principle
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 reach the state of saturation and 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 processesare carried out unceasingly and the purpose of drying can berealized within a short time.

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 heat sensitivity and is toxic and not permitted to destroy its crystal in drying process.
Technical parameters
Features
When oil is used to heat, use automatic constant temperature to 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.
