2021-6-5 Fluidized Bed Dryer is working on the principle of fluidization of the feed material. Fluidization is the introduction of hot air at high pressure through a perforated bed of moist solid particles. In the fluidized bed dryer, the particles are particularly suspended in a mobile gas stream (Hot Air), the air serves as a boiling liquid in the sense that the particles are first lifted upward and then they fall back.

2021-5-13 Principle: In the fluidized-bed dryer, hot air is passed through a perforated bottom of the container containing granules to be dried. The granules are suspended in the air stream and rise from the bottom. This condition is called a fluidized state. Hot air surrounds each granule to dry it completely.

2021-3-27 Fluid bed dryer works on a principle of fluidization process. In fluidization process, hot air or gas flow is introduced through the bed of solid particulates. This gas or air will move upwards through the spaces between the particles. As the velocity increases, upward drag forces on the particles increase and at a stage become equal to the gravitational forces beneath. Hence the bed is said to be fluidized and

The dryer is direct heating type which brings heated air into direct contact with the raw materials. Heated air is blown up from the dispersion plate evenly, and the raw material gets into motion on the dispersion plate and is suspended in heated air, forming uniformly mixed layer like a fluid, which is known to as fluidized bed.
