Fluidised Bed Dryers

Fluidised Bed Dryers provided the good solid mixing, high rate of heat and mass transfer and transportation of material. Fluidized bed dryers are more suitable for the drying of fine powder particle sizing from 10 to 2000 mm as compared to other conventional drying methods.

Fluidised bed dryers is achieved by passing a gas stream from the bottom of a bed of particulate solids. At low velocity of gas the bed stays in static condition, and the particles lay on a gas distributor plate. The fluidising gas passes through the distributor and it is uniformly distributed across the bed. The gas velocity is increased such that to achieve the fluidization of bed, gas velocity at which the bed achieves the fluidization is known as minimum fluidization velocity.

A Fluidised bed dryers operates at gas velocity higher than the minimum fluidization velocity of material under processing. This increase in the gas velocity result in suspension of particles under processing in air, this appears as the boiling of solid particles of material under processing.
