SZG Series Conical Vacuum Dryer
SZG Series Double Taper Vacuum Drier is a new generation drying device developed by our factory on the basis of combining the technology of same products. It has two connecting ways, i.e. Pulley 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 machinery seal or rotating joint made from abroad. On the basis, we also developed SZG-A. It can carry out steeples speed change and constant temperature control.
As a special factory in drying industry, we provide hundreds of set to customers for their use. As for working medium, it may be high temperature conduction heat oil or middle temperature steam. For drying the adhesive raw material, the factory has designed specially a stirring plate for you.
It is suitable for the raw materials that need to concentrate, mix and dry 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 oxidize, volatilize and have strong heat sensitive and toxic and not permitted to destroy its crystal in drying.
1. Let heat source （for example, low pressure steam or heat conduct oil） pass through the sealed jacket. The heat will be transmitted to raw material to be dried through inner shell;
2. 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;
3. The raw material exists at the state of 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 drecovered in time. The inner moisture （solvent） of raw material will infiltrate, evaporate and discharge continuously. The three processes are carried outunceasingly and the purpose of drying can be realized within a short time.
1. 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 from 20-160°C and within ±2°C.
2. Compared with ordinal drier, its heat efficiency will be over 2 times;
3. The heat is indirect. So the raw material can not be polluted. It is conformity with the requirement of GMP. It is easy in washing and maintenance.
