Features

Double Cone Rotary Vacuum Dryer - drying machine

When oil is used to heat, use automatic constant temperature control. It can be used for biology and mine products. Its temperature of operation can be adjusted from 20160 and within ± 2.

Compared with ordinary drier, its heat efficiency will be over 2 times.

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.

Principle

Let heat source(fro example, low pressure steam, heat or 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 continously. The purpose of reinforced drying can be realized.

The raw material exists at the state of 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 moister(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.

Application

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 indusries. Particularly it is suitable for the raw materials that are easy to oxidize, volatilize and have strong heat sensitive and toxity and not permitted to destroy its crystal in drying.
