Double conical vacuum dryer for powder and granule chemical material with organic solvent and vacuum rotary dryer
Description
Rotating vacuum dryer is a new dryer that integrates mixing and drying in one body, equipped with condenser and vacuum pump. The dryer is advanced in design, simple in inner structure, easy for cleaning, convenient in operating and improving work environment. Meanwhile raw material is rotating accompanying with the rotating of container, the wall of container can not accumulate material, make raw material drying quickly and have good quality. It can widely apply to dry raw materials of pharmaceutical industry, chemical industry, foodstuff industry and so on. The equipment is in conformity with the requirements of GMP.
Principle
Let heat source (for example, low pressure steam or heat conduct oil) pass through the sealed jacket. The heat energy will transmit to raw material through the inner wall.
The tank is rotated slowly and raw material inside is mixed continuously. The drying effect will be better.
The raw material stay at a state of vacuum. The solvent will be discharged through the vacuum pump.

Specifications:
1. Used for powder and granule
2. Energy saving and high efficiency
3. Comply with GMP
Applications:
1. Material that cannot undertake high temperature.
2. Material that is easy to oxidize.
3. Material that do not permit to destruct.
4. To recover material with residual volatile.
5. Material with vigorous irritative and toxicity.
6. Biology products and mine.
7. Dry raw materials of pharmaceutical industry, chemical industry, foodstuff industry, dyestuff industry at low temp etc.

Note:
For the raw material, if its volume has great changes before and after drying, then its filling coefficient may be increased or decreased suitably.
Speed adjusting motor of 0~6rpm might be chosen according to the user’s requirements. The following aspects should be pointed out when to order:
1. The above mentioned parameters are calculated based on material density of 0.6g/cm3. if it’s over, please point out.
2. If glass lining for interior surface is required, please point out.
3. if the material is explosive or flammable, it should be pointed out when to order.
