Model ZPG inner heating cylinder stirring vacuum drier is widely used for chemical
industry. Particularly, it is widely used for organic semi-finished products and
dyestuff industry. It adopts steam or heat conduction oil or water to enter into
the jacket, to heat raw materials indirectly. Under vacuum state, pump the damp,
therefore it is suitable for drying raw materials that are easy to oxidize
under high temperature, and raw materials that are easy to produce powder dust
during the period of drying, as well as raw materials that solvent need to be
recovered.

The structure of machine is compact, its operation is simple, its performance is
constant and its maintenance cycle is long. At high or low temperature under
suitable condition, this equipment is proved to be suitable for drying powder,
