The Hollow Paddle Dryer is a high efficiency and energy saving Dryer. It can handle powders, paste or slurry. It has large heat conduction area which can remove the water quickly.
Adopting saturated steam, hot water or heat conducting oil as the heating medium, the paddle dryer is an indirect-heating and low-speed stirring Drying Equipment, and both the continuous and intermittent operations can be carried through. It can be used for product cooling with the usage of cooling medium.The paddle dryer is mainly used for the drying or cooling of powder, granular, cake-shaped, paste and the slurry-like materials.
1. The cost of the blade dryer is low: The unit effective volume has very large heat transferring surface, so the processing time is shorted, the size of the equipment becomes small. The building area and place are sharply decreased.
2. The range of material to be processed is wide: Heat sensitive material and the materials to be processed under high temperature might be processed with different heating media. The normal media are: steam, thermal oil, hot water and chill water. It might be continuous or batch operation, widely used in many areas.
3. The pollution is less: Without any carrying air, very little powder is carried out. The solvent evaporated is very few, it easy to be processed. For the material that might cause pollution or the solvent to be recovered, it might adopt sealed circulation.
4. The operation cost is low: 1hour/day.operator is enough for normal operation. Low stirring speed and reasonable structure, the worn amount is few, and the maintenance fee is low.
5. Steady operation: The material particles fully contact heat transferring surface, because of the special compressing and swell-stirring effect of the wedge shaped blade. The difference of the temperature, humidity and mixing effect are very small in the different axial area, so to ensure the stability of process.
