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 raw material inside  it is mixed continuously ,The purpose of reinforced drying can be relized ;

The raw material is under vacuum .The drop of steam piressure makes the moisture (solvent)at the surface of raw material reach the sate of saturation and evaporate .The solvent will be discharged  through vacuum pump and recovered in time .The inner misture (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 .

 Sketch of structure

Appliations

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 .Particuarly 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.

Features

When oil is used to heat ,use antomatic constant temperature to 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.
