Vacuum Rotary Double Cone Dryer for Chemical , Medicine , food powder
Main Applications:
It is suitable for the raw materials that need to concentrate, mix and dry at low temperature(eg. biochemistry products in chemical, pharmaceutical and foodstuff indusries).
1. materials that are easy to oxidize
2. materials that are easy to volatilize
3. materials that having strong heat sensitive or toxic
4. materials that should not destroy its crystal in drying
Principles:
1. heat source pass through the sealed jacket
2. the heat will be transmitted to the raw material to be dried through inner shell
3. under driving of power, the tank is rotated slowly and the raw material inside it is mixed continuously. then the purpose of reinforced drying can realized
4. the material is at a vacuum state, the drop of steam jpressure makes the moisture at the surface of raw material become saturation and will evaporate
5. the solvent will be discharged through vacuum pump
6. the inner moisture of raw material will infiltrate, evaporate and discharge continuously. these three processes are carried continuously and the purpose of drying can be realized within a short time
Main features
1. Drying or extracting water or solvents from humid powder and small granule products
2. Drying Chamber volume:100-5000L
3. GMP design
4. Heat supply can be steam,hot water and hot oil.
Working Principle
SZG series double cone vacuum dryer is an indirect heating batch type drying processor. The bi-conical drying chamber has heating jacket which can be filled with hot water, steam or thermal oil. During the operation, vacuum condition is created by the vacuum pump and wet material flows alongside the heated inner surface with the rotation of drying chamber. Heat transfer happens between wet material and heated surface of drying chamber. The evaporated moisture is sucked out by vacuum pump. If the evaporated moisture needs to be recovered, condenser and buffer tank can be equipped.
SZG series double cone vacuum dryer has been widely used in food, chemical and pharmaceutical industry for drying:
1) Powder, small granule or fiber products with good flowability
3) Easy-oxidized, toxic, explosive or heat sensitive humid masses after centrifugation or filteration
2) Moisture is organic solution and need to be recovered
Technical Advantages
1) Multi-functional: The central body is a bi-conical chamber which can rotates with different speed and direction. Except drying or extracting solvents, it also can be used as an effective fast blender or homogenizer.
2) GMP design: The drying chamber is made according to GMP standard which is mirror polished, no dead corners for washing or cleaning and safe for both operators and products.
3) Multi-product: The drying chamber can be lined with glass or enamel interior surface for high corrosive materials
4) No-lumps: High speed cutters can be equipped to break the lumps or agglomerates which can considerably shorten the drying time and ensure uniform drying.
5) Effective filtering system: The three-head filtering unit can perfectly filter out the powder and just let solvent vapors go through with very low pressure drop.
6) Easy-operation: Vacuum conveyor can be equipped for automatic feeding and discharging.
