Fluidized mattress dryer (FBD) is recognized and broadly used products in granulation location of pharmaceutical manufacturing. It's Employed in the granulation system for drying the material to get preferred dampness content during the pill formulation granules necessary for fantastic compression of tablets.
Despite the aforementioned strengths, fluidized bed dryers even have their limitations. One of many extra considerable limits is their incompatibility with very gentle or fluffy resources, as these can be blown out of the mattress through the upward flowing fuel.
HEPA filter resulting from its hugely great mesh ( 0.3micron) increases the strain drop throughout it and consequently the higher potential suction blower might be needed.
The dryer is manufactured from SS316, an austenitic chromium-nickel chrome steel that contains a deliberate level of molybdenum, rising general corrosion. The construction on the Vertical fluidized mattress dryer is shown within the determine underneath.
The fluidized condition of granules creates turbulence which can trigger attrition of some materials resulting in the production of fines
However, the good particles are blown-up and continue being suspended from the air channel, If air is allowed to flow via a bed of sound material from the upward path which has a velocity greater compared to the settling price with the patches.

It is necessary to apply explosion prevention measures, such as utilizing inert gasoline, protecting right air flow, and staying away from using ignition resources.

FBD bowl loading: In a tablet production course of action, The full Procedure of the Fluidized bed drier starts with the loading of moist granular materials through the granulator. The moist granules to be dried are placed in the removable bowl of a vertical FBD.
4. The air velocity is elevated with time. If the velocity on the air is greater than the settling velocity in the granules, the granule stays partially suspended while in the air stream.
This suspension allows for uniform Make contact with between the particles as well as the drying or granulating medium, guaranteeing effective warmth and mass transfer.
When processing poisonous or flammable substances, conventional warm air fluidized bed dryers are certainly not an excellent Alternative given that There exists a click here risk of fire or explosion if flammability limitations are exceeded.
