Fluidized bed dryer (FBD) working principle. The working principle of fluidized bed dryers is "the process of fluidization". At the start, hot air is introduced at high pressure through the bed of solid particulate. This air passes through the solid particles at a velocity sufficiently high to suspend the solid in a fully fluidized state.

Fluidized Bed Dryer works on the principle of fluidization. When hot air is passed through a granular bed (i.e., non-sticky wet granules), friction occurs between the granular surface and hot air, that leads to pressure drop (decrease in pressure). On increasing the velocity of air, the pressure increases and a point is attained at which the ...
