Chemical double cone rotary vacuum drying machine

Description of Double Cone Rotating Vacuum Dryer:

Double Cone Rotary Vacuum Dryer, which is a conducted heat transferring rotary dryer of batch operation, is mainly suited for vacuum drying of powder or granules form materials.

The double cone rotary Vacuum Dryer is a double cone rotary tank. Under the vacuum condition in the tank, steam or hot water is introduced into the jacket for heating.

The heat is in contact with the wet material through the inner wall of the tank. The water vapor evaporated after the wet material absorbs heat and is pumped away through the vacuum exhaust pipe through the vacuum pump. Because the tank body is in a vacuum state, and the rotation of the tank body makes the materials constantly turn up, down, inside, and outside, it speeds up the drying speed of the materials, improves the drying efficiency, and achieves the purpose of uniform drying. The double cone rotary vacuum dryer system is mainly composed of a double cone rotary vacuum dryer, condenser, dust collector, vacuum pumping system, heating system, cooling system, electric control system, etc.

Note: 1. The heating source in the flow chart is hot water. The heating source also can be steam or thermal oil.
2. If you do not need to recover the organic solvents, the condenser will be not needed.

Application and features of Double cone rotating vacuum dryer:

Double cone rotary vacuum dryer is suitable for vacuum mixing and drying powder and granules materials in pharmaceutical, nutriceutical, food and chemical, new energy, battery materials industry. For example: Thermal sensitive materials, the materials that is easy to oxidize, the materials that has solvent to recover, and the materials that needs very low moisture content, etc.

1. When the heat source (hot water, low-pressure steam, or thermal oil) pass through the sealed jacket, the heat will be transmitted to raw material through the inner shell;
2. Under the action of driving power, the tank is rotated slowly and the raw material is mixed continuously. The purpose of reinforced drying can be realized
3. The raw material is under vacuum condition. When steam pressure is dropping, it makes the moisture (solvent) at the surface of the raw material becomes saturated and then evaporates. The solvent will be discharged through the vacuum pump.
4. The moisture (solvent) of raw material will infiltrate, evaporate and discharge continuously.
5. The production processes are carried out continuously and the drying can be done in a short time.
