Fluidized mattress dryer (FBD) is well-known and extensively applied devices in granulation space of pharmaceutical production. It really is Employed in the granulation system for drying the fabric for getting ideal moisture written content in the pill formulation granules necessary for fantastic compression of tablets.
Central into the Procedure of the fluidized bed dryer is definitely the concept of “fluidization”. This process takes place when a particular volume of sound particulate material is manipulated underneath specific problems this kind of that the mixture on the sound and fluid acts just like a fluid.
Fluidization is the process whereby a granular materials in its authentic good condition transitions into a fluid-like point out employing a fluid, which can be air or a liquid. This basic principle underpins how a fluidized mattress dryer functions, proficiently drying out powdered or granular components.
Even so, HEPA filter as a consequence of its hugely high-quality mesh ( micron) raises the stress dropo throughout it and hence the higher potential suction blower is likely to be necessary to creat fluidization influence.
The inlet air temperature and humidity should be carefully managed to attain the specified drying amount and decrease the chance of degradation or other alterations during the drug substance.
Also Be certain that the right Doing the job of HVAC program by checking the strain differential of region more info & temperature and RH.
The Doing the job principle of the Fluid mattress processor relies on fluidization. Fluidization Inside a move of fuel or liquid, stable particles are held floating upward by a approach referred to as fluidization. When comparable-sized and-shaped particles are exposed to an upward stream of chilly air during freezing, fluidization usually takes spot.
A enthusiast is out there at the best on the circulating warm air. Fresh new air enters; filters and heat exchange are connected serially to warmth the air on the expected temperature.
Purging air is provided underneath with the impeller to forestall stickiness within the granules towards the impeller and likewise assists protect against contamination.

FBD bowl loading: In the pill manufacturing approach, The complete operation of a Fluidized bed drier starts Along with the loading of damp granular substance within the granulator. The moist granules to be dried are placed within the removable bowl of a vertical FBD.
FBD refers to a Fluidized mattress dryer that is usually Utilized in the pharmaceutical business to lessen the dampness content of pharmaceutical granules.
Install click here the SFM: The SFM really should be mounted in an appropriate location within the fluid mattress dryer system. The set up locale should be thoroughly chosen to ensure that the SFM can properly measure the movement charge of the drying content.
The specified or specific finish of drying procedure is accomplished by testing loss on drying (LOD) at the end of drying approach.
