SZG series rotary double cone powder mixer

Working Principle

Raw material is charged in batches & is subjected to indirect heating while at the same time undergoing rotary motion of the cone assembly. The conical shape of the dryer ensures efficient circulation of hot liquid heating media.

Drying takes place when heat flows from outer cone through a jacket, and vacuum is applied in the inner cone. The drying operation is based on the principle that water or other volatile product moves from a zone of low pressure. This is accomplished by warming the product to be dried to raise the vapour pressure of the zone of low pressure. This is accomplished by warming the product to be dried to raise the vapour pressure of the absorbed or free liquid, by vacuum, or by sweeping it away with an air current. Thus the essential conditions for effective drying are efficient and uniform heat transfer throughout the batch and rapid removal of the vapour.

Material to Be Dried

It is suitable for the raw materials that need to concentrate,mixed and dried at low temperature(for example,biochemistry)products in chemical,phamaceutical and foodstuff industries.Particularly it is suitable for the raw materials that are easy to be oxidized,volatilized and have night heat sensitivity and is toxic and not permitted to destroy its crystal in drying process.

Characteristics
◎When oil is used to heat,use automatic constant temperature control.It can be used for drying biology products and mine Its temperatu re of operation can be adjusted form 20-160oC.
◎Compared to ordinal d ryer,its heat efficiency will be 2 times higher.
◎The heat is indirect So the raw material can not be polluted.
◎It is in conformity with the requi rement of GMR It is easy in washing and maintenance.
