Fluidized Bed Dryer Working Principle

If air is allowed to flow through a bed of solid powdered material in the upward direction with the velocity greater than the settling rate of the particles the solid particles will be blown up and become suspended in the air stream.

Fluidized bed dryer working principle.

Position of the air distribution plate. If air is allowed to flow through a bed of solid powdered material in the upward direction with the velocity greater than the settling rate of the particles the solid particles will be blown up and become suspended in the air stream. It has a direct bearing on the airflow pattern inside the fluid bed dryer. This results in an optimal mix of gas and product so that high heat transfer and an optimum physical reaction speed are achieved.

The equipment works on a principle of fluidization of the feed materials. The principle of fluidized bed dryer. Fluid bed dryer works on a principle of fluidization of the materials. Fluidized bed dryer also called fluid bed dryer is a kind of equipment used extensively in the pharmaceutical industries to reduce the moisture content of pharmaceutical powder and granules.

In a fluidized bed dryer a product or solid is made fluid by an upward moving flow of gas. The principle of fluidized bed dryer. In fluidization process hot air or gas flow is introduced through the bed of solid particulates. The mechanical movement of the fluidized bed dryer strengthens this effect.
