Description

Double tapered vacuum dryer Application
♦ It is suitable the raw materials that need to 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.


Double tapered vacuum dryer Principle
♦ 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;

Under driving of power, the tank is rotated slowly and the raw material inside mixed continuously. 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 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.

Double tapered vacuum dryer Feature
♦ When heating the oil, use automatic constant temperature control. It can be used for drying biology products and mine. Its temperature of operation can be adjusted from20~160°Cand within ± 20C.
Compared with ordinal drier, its heat efficiency will be over 2 times;
The heat is indirect. So the raw material cannot be polluted. It is conformity with the requirement of GMP. It is easy in washing and maintenance.

♦Its heating has three ways i.e. steam, hot water, hot conduction oil.
♦When order please indicate the temperature of raw material to be undertaken or the operation temperature of drier in order to choose or provide suitable heat source for you.
♦When dry viscous raw material, our factory will design special siring device in the chamber.
♦The cost of complete equipment should be increased in accordance with the needs.
