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.
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
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.

Q: What information should be provided in order to get a proposal or quotation?
A: Our double cone vacuum dryer can be customerized. Before we can work out a detailed quotation, we have to know the following information:
1) What raw material are you going to dry?
2) Moisture content before drying? Target moisture content of dried powder?
3) Moisture type? water or other solvents?
4) Your recommended drying temperature?
5) Heat souce? Steam or thermal oil ?
6) Construction material ?
Q: How the dryer will be delivered ?
A: Drying chamber is fixed in a steel frame and then loaded into container. When drying chamber volume is more than 2500L, it can't fit into normal container for shipping.
Q: Do you provide free drying test?
A: Yes. We have pilot plant for free drying test.
Q: What standard models do you have?
A: We have the following standard models with main specifications:
