Rotary Dryer or Fluid Bed Dryer FEECO International Inc.

Rotary dryers require less energy to dry material, and energy consumption is reduced when running at lower capacities. Fluid bed dryers are considered to be more thermally efficient than rotary dryers, however. This is because the heat transfer is maximized due to the fluidization effect; each granule is surrounded by the drying air.
