The Siutable for vacuum drying and mixing of grnular powder. can be dried to have very low content of moisure Therefore it can be used to further dry the materials with relaively low content of moisture. For drying the matrias conaning sovets or posous gas. the machinc alsohas the advantage of retrieving the former easily. The machine is especially suitable for low temperature drying of materals like atibiotic and vitamin drugs which are temperature sensitive.

The machine is capable to attain high vacuum. It's interior structure is simple and lined with complete smooth surface, therefore it can becleaned easily and the stuffs within the vessel can be completely discharged. Besides, as the wall is rotating, it does not allow any stuff sticking onits surface, it has high coeffcient of heat transfer. The dry time is shorter when the machine compares with the chest dryer. The materieal wear isless when it compares with the agitator type blender. It' s advantages are obvious in obtaining better guanlity of production.

The vessel used in the machine is gass-lined or made of stainless steel, The sealing approach in the machine can be mechanical sealing or stuffing sealing.
