Low Temperature Rotary Vacuum Drying Systems, Rotary Vacuum Paddle Dryer is a jacketed cylindrical horizontal vessel with a a large diameter hollow shaft. The jacket and hollow shaft with paddles can be heated with hot water, steam or any other thermal fluid capable of providing a large indirect heat transfer area. Externally heated through jacketlimpet coilsInternally heated Agitator shaft for maximum heat transfer areaEfficient rotary joint to inject heating media into agitator and remove condensatePrepiped with heating medium inlet to dryer and condensate out to headers.
