Explosion Proof Batch Fluidized Bed
The 300XP model fluid bed is more than just a conventional fluid bed dryer. As an added feature, the 300XP model uses a filtration step to recover a solvent from a slurry.
In the filtration step, a pressure difference is set up. It is the difference in pressure that forces the liquid solvent through a screen or cloth. The large solid particles are trapped by the screen or cloth and build up as a cake. Once the solvent is physically removed from the slurry, the wet cake in the product bowl is transferred to the fluid bed dryer.
The fluid bed dryer is designed to fit the product bowl where the remaining solvent is evaporated using a warm gas stream. In the fluid bed, the particles become suspended in the gas stream, and the bed of powder behaves as a boiling liquid. The bed of powder behavior depends on the gas velocity.
The type of fluidized bed is dependent on the gas velocity and the physical properties of the powder. Since the gas stream mixes and suspends the bed of material, fluid beds provide gentle and rapid drying applications.
