SZG Chemical industry double tapared vacuum dryer for oxidize material/vacuum dryer

SZG Series Double Tapered Vacuum Dryer

1. The principle of work

In airtight sandwich tube such as heat energy (hot water, low pressure steam or heat conduction oil), the quantity of heat inside the shell to be dry material. In power drive, tanks a slow rotation, tank material continuously flipping, mixed, from inside the wall surface accept quantity of heat, so as to achieve the purpose of aggrandizement is dry. The materials under vacuum condition, the steam pressure drop make the material of surface water (solvent) reached saturation and evaporation, and the vacuum pump discharge recovery in time. Water inside of materials (solvent) continually to surface infiltration and evaporation, releasing, three process continuously, and the material in a short period of time to dry purpose.

2. Product features

A ROM watts embellish valve high vacuum the unit may be produce high vacuum degree, limits the vacuum high vacuum evaporation dry, meet the thermal material low water content low temperature drying requirements.

A double cone drying machine clip set inside the heating medium low temperature steam, because the water vapor in the process of heating have clip, heat transfer K value for hot water heating of 3 times. So in double cone drying machine this unit volume heat transfer area slants little dryers can still fast effective provide dry heat (per kg offer 550 calories quantity of heat low temperature steam).

3. Applications

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.
