In Fluidized Bed Dryer, the process air is supplied to the bed through a special perforated distributor plate and flows through the bed of solids at a velocity sufficient to support the weight of particles in a fluidized state. Bubbles form and collapse within the fluidized bed of material, promoting intense particle movement. In this state, the solids behave like a free-flowing boiling liquid.
Advanced method of drying wet/semi-wet solids
Unlike in Tray Drying every solid particle is floating of Air which is blown from down to up creating material layer in fluidized state
Almost every wet particle directly receives the heat energy from hot Air resulting in uniform and quick drying
