A Secret Weapon For FBD principle

The FBD approach can also be employed for granulation, wherever good powders are remodeled into granules with improved flowability, compressibility, and uniformity. The fluidized bed facilitates the even distribution with the binder Option, bringing about uniform granule formation.

The principle at the rear of a Fluidized Bed Dryer revolves throughout the principle of fluidization. Fluidization is a method through which reliable particles are created to behave like a fluid by passing a fuel or liquid by them.

FBD functions about the Principle of Fluidization. Fluidization is often a phenomenon where the packed mattress of damp powder particles Or particulate solids, when are exposed to a thrust and flow of hot fluid (In such a case Incredibly hot Air), flowing from The underside on the bed upwards, forces it to type a flexible mattress (which appears similar to a Mattress of Boiling H2o), as well as the mattress of floating particulate solids is termed as Fluidized Bed.

Senieer: A renowned Indian company featuring an array of fluid mattress dryers from lab-scale to production scale.

Moisture Removal: The humidity-laden air rises in the fluidized bed, carrying the evaporated moisture with it. This continual circulation of air in the mattress assures uniform drying.

In FBD, a sizzling air (fuel) is passed through a perforated bottom of your container holding the solution granules that have to be dried at higher tension.

This drags and condenses the water Or moisture from your air and makes it dry. The chilled water piping (source and return line), and also, the control valve are beyond the AHU.

Thus, watchful analysis of every drying process is vital to make certain that the advantages might be capitalized, along with the disadvantages is usually managed or mitigated.

The Preliminary startup move in the fluid mattress dryer is to include a fresh new batch of moist granules to the solution chamber. The Feeding material might be sucked within the high shear mixer chamber via a feeding tube under destructive stress.

These are the most basic sort of fluidized mattress dryers. The fabric is fluidized from the upward FBD usages in pharmaceuticals move of air or gas without any supplemental mechanical agitation. Static fluidized bed dryers are easy and cost-successful.

In the event the gasoline or air velocity is enhanced, it reaches a point where the drag drive exerted to the particles overcomes their bodyweight, creating them to become suspended within the fluidized bed.

The heated air is released into a chamber under the vibrating conveyor deck. It passes throughout the perforated conveying surface, through the fluidized mattress of solids, and into an exhaust hood.
