China Szg Series Concial Vacuum Dryer for Foodstuff Industry

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.
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.
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.

Speed adjusting motor of 0-6rpm might be chosen according to the user's requirements. The following aspects should be point out when to order:
1. The above-mentioned parameters are calculated based on material density of 0.6g/cm3. If it's over, please point out.
2. If certificate for pressure vessel is required, please point out.
3. If glass lining for interior surface is required, please point out.
If the material is explosive, or flammable, the calculation should be made according to trial result.
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 ° C.
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.
