ZPG Vacuum rake dryer

1. General description of Vacuum rake dryer

Vacuum rake dryer is mainly used for drying explosive, easily oxidized and paste materials. Under vacuum conditions, the boiling point of the solvent is reduced, and the air is isolated, so it avoids oxidation, overheating and deterioration of material during the drying process. The heating medium (hot water, heat transfer oil or steam) is introduced into the jacket. A certain amount of wet materials are added into the drying chamber. The rake shaft stirs the materials to heat them evenly. After the materials meet the drying requirements, open the discharge valve at the lower part of the drying chamber to allow the materials to move to the middle under the stirring of the rake shaft for discharging

2. Feature of Vacuum rake dryer

1. The machine adopts large area jacket heating, heat transfer area is large and heating efficiency is high.

2. High evaporation intensity, generally 10 ~ 15kg (water) / m2. h

3. After the solvent vapor entrainment is filtered by the bag filter, there is no environmental pollution and the product recovery rate is high.

4. The machine is equipped with stirring device, so that the drying of slurry, paste and paste materials can be carried out smoothly.
