Fluidized Bed Dryer, Fluid Bed Dryer Manufacturer and ...

Fluidized bed dryers operate on the fluidization principle, which is the conversion of a substance from a rigid solid-like state to a dynamic fluid-like state. Hot gas or air is introduced into the material-holding region via a perforated distribution plate in this process. This hot gas pushes its way through the gaps between solid particles.
