Fluidized bed dryers are greatly used in numerous industries for drying granular and powdered resources. The fundamental principle consists of suspending the fabric in the stream of air or fuel, creating a fluidized state that boosts the drying system.
At substantial temperature, the particle absorbs much more heat for evaporation and increasing evaporation charge As well as in small temperature, considerably less warmth is absorbed as well as evaporation fee is decreased.
The soaked solids are lifted from The underside and suspended in the stream of air (fluidized condition). As the recent air passes amongst the particles it will take the excess dampness with the particles So drying the particles.
The leading principle at the rear of the Doing the job of your fluid mattress dryers is, Air is permitted to movement via a mattress of solid powdered materials within an upward direction. This made so that the velocity is increased as opposed to location charge of all particles.
