The FBD approach operates to the principle of fluidization, the place a bed of solid particles is remodeled into a fluid-like condition by passing a fuel or liquid through it.
On the other hand, the stable particles are blown-up and stay suspended within the air channel, If air is allowed to movement via a bed of strong product from the upward way that has a velocity greater compared to the settling price on the patches.
Find the BAG LOCK icon to lock the finger bag assembly and RELEASE icon to unlock the finger bag assembly.
Inert bed substance: sometimes utilized to Enhance the fluidization with the solution, particularly when the products is rather light-weight or has lousy flowability.
Upon heating, the recent air is blown through the perforated distributor plate situated at the bottom of the leading equipment housing unit. This process brings about an upward stream of air that passes through the product or service bed.
Fluidization: Since the air flows upward, it passes through the bed of solid particles. The upward pressure of the air will cause the particles to be suspended and behave like a fluid. This fluidization makes sure that your complete bed is in motion, exposing all particles to the recent air.
Fluidized Mattress Dryer is working on the principle of fluidization on the feed substance. Fluidization would be the introduction of warm air at superior pressure via a perforated mattress of moist stable particles.
Horizontal Fluidized Mattress Dryers: These dryers Use a horizontal drying chamber. These are very well-fitted to resources that are very easy to fluidize and don't require a high drying temperature.
2. The granules are lifted from the bottom and suspended from the stream of air this issue is referred to as fluidized state.
This equipment might have some really serious problems if It isn't dealt with in the correct way. Here are several of the common complications:
The particles are lifted and after that drop back again randomly so that the resultant combination of good and gas functions just like a boiling liquid. This ailment is known as a fluidized point out. The excellent fuel-sound Get in touch with results in far better heat and mass transfer than in static and relocating beds.
When the gasoline or air velocity is elevated, it reaches a degree wherever the drag power exerted on the particles overcomes their fat, creating them to be suspended during the fluidized bed.
The heated air is launched right into a chamber down below the website vibrating conveyor deck. It passes in the perforated conveying surface area, through the fluidized mattress of solids, and into an exhaust hood.
5. Immediately after some time, a point of strain is attained at which frictional drag over the particles is equivalent for the pressure of more info gravity.
