The FBD procedure can be used for granulation, in which great powders are transformed into granules with improved flowability, compressibility, and uniformity. The fluidized bed facilitates the even distribution in the binder Option, bringing about uniform granule formation.
Central on the Procedure of the fluidized bed dryer is the notion of “fluidization”. This method happens when a certain number of sound particulate material is manipulated under precise situations this kind of that the mixture in the sound and fluid functions like a fluid.
Nevertheless, If your powder is sticky Or hygroscopic, there are actually probability of powder forming sticky layer around the finger bag surface, therefore, just shaking from the pneumatic cylinder may well not assistance.
Right after a while, some extent of pressure is arrived at at which frictional drag about the particles equals the power of gravity.
The underside of the fluidized-bed dryer is perforated, wherever sizzling air moves through the granules to generally be dried.
The need to suspend the complete bed in gas ends in major strain drops and superior Vitality fees.
It entails using a fluidized bed to suspend and agitate particles, letting for successful drying and granulation.
Some products may well attrite as a result of more info the fluidized point out of granules’ turbulence, making fines.
A fluid bed processor is a complicated approach if talking about the earlier like FBD and RMG used to carry out a similar purpose that's included the while procedure, hence new system is a very effective strategy to reduce the production time, workforce and price.
Multi-shaker bag filter: this filter is split into two or even more sections, that has a individual filter bag in each. Bags are cleaned individually by shaking the filter, although fluidization continues in the opposite here sections, for more quickly plus more economical manufacturing.
Sophisticated operation: Fluidized bed processors need a superior diploma of operator skills and training to function successfully and securely, which may be difficult for a few businesses.
• Inspection of FBD bag is performed for its integrity in advance of & after the utilization and document in “FBD bag logbook”.
When, The underside on the chamber has a mesh/ perforated sheet for passage of of incredibly hot air with the plenum chamber, the top is right linked to The underside in the Fluidization Chamber (often called Growth Chamber) with the help of the D form hollow tube inflatable gasket.
When processing toxic or flammable substances, common warm air fluidized bed dryers will not be a very good Resolution because there is a possibility of hearth or explosion if flammability constraints are exceeded.
