WebJul 19, 2024 · Fluidized bed drying is a well-known process that has been widely used in the dairy and pharmaceutical industries for drying, granulating, and coating operations. WebFluidized bed drying subjects a wet material to a rising stream of hot gas that flows through a perforated distributor plate or membrane. The heated gas lifts and surrounds each individual particle, causing the solid material to flow freely and behave like a fluid. This fluidizing effect enables efficient, continuous, consistent heat transfer ...
