Fluidized bed dryer (FBD) working principle
Fluidization is the process wherein a granular material in its original solid state transitions into a fluid-like state using a fluid, which could be air or a liquid. This fundamental principle underpins how a fluidized bed dryer functions, effectively drying out powdered or granular materials.

Principles & Applications of Fluid Bed Dryer (FBD)
Here are the key principles governing fluid bed drying: Fluidization: When air is introduced at high velocity through a perforated distributor plate at the base of the drying chamber, it lifts and suspends the particles in the air stream. These suspended particles begin to behave like a fluid, hence the term "fluidization."
