10–3000 μm), or fluidized bed drying (particle size 50–5000 μm) (Chandran et al. 1990). While liquid material is directly fed to spray and flash dryers, the fluidized bed dryer can only be fed with wet solids. Fluidized bed drying is a technology, which is widely applied in industry for the drying of particulate solids.

Drying in the Fluid Bed Dryer TG 200 makes use of the fluidized bed process, a technique similar to the one used in large industrial dryers. Ambient air is drawn in through a filter. A blower moves the air across the heating elements, and ultimately forces it through the perforated plate and into the detachable drying container.

A fluidized bed occurs when a quantity of solid particles (generally contained in a holding vessel, most commonly a fluid bed processor) are placed under appropriate conditions to cause the mixture to behave as a fluid. This is typically done by forcing pressurized air, gas, or other fluids through the bed of solid particles.
