A fluidized bed dryer works by passing Hot air with high pressure through a perforated bed of moist solid particles. The hot air passes at a velocity greater than the settling velocity of the particles resulting, particles starting to suspend in the air. As the moist particle suspends in hot air, the moisture content of solid particles reduces ...

Fluidized Bed Dryer Principle The bottom of the fluidized-bed dryer is perforated, where hot air moves through the granules to be dried. The granules rise from the bottom of the air stream as they are suspended in it. The process is known as fluidization. To dry each granule completely, hot air surrounds it.
Static Bed Height The transition velocity was almost independent of the static bed height, which varied from 0.4 to 1.0 m (Grace and Sun 1990). Similar results were reported by Cai (1989) and Satija and Fan (1985) with (Hmf/Dt) > 2. On the other hand, for a shallow fluidized bed of (Hmf/Dt) < 2 with Group B and D particles, Canada et
