Double Shaft Paddle Dryer

The KJG double shaft paddle dryer is a conduction heating and low speed rotating dryer which features a jacket on the body of the dryer, a hollow blade on a hollow shaft, and a heat source filling the blade. The wet material is stirred by the paddle, which dries the material as it transfers heat. According to client-side demands, we can also design the hollow screw dryer with four shafts.

Features of the Double Shaft Paddle Dryer
1. The thermal efficiency reaches as high as 80%-90%. Heat transfer coefficient K is 100-300Kcai/h.m2℃. Evaporation capacity is 10-30Kcai/h.m2.
2. The horizontal dryer supports heating, evaporating and cooling processes, continuous operation and batch operation, and vacuum drying for thermal sensitive material as well as normal drying.
3. Heating source: heat can be conducted via oil, steam, water, hot air or cooling fluid.
4. The oar of the double paddle dryer provides a large heating area.
5. The particle vacuum dryer is widely used for organic and inorganic granules, sticky material or material with high water content.
