A continuous fluid-bed system is a machine in which a continuous flow of “wet” powder, granular or flakes material is conveyed over a perforated bed. Hot drying air is blown through the holes of a perforated plate. The wet solids are lifted from the bottom and causes the solids to behave as a fluid. Fluid bed dryers, as their name suggests, are used for drying materials such as granules, tablets, powders, fertilizers, and plastics.
