The FBD procedure can be a broadly applied approach from the pharmaceutical business for drying and granulation. It offers many advantages, such as uniform drying, improved merchandise quality, and minimized drying time. Right control and checking of method parameters, and typical machines upkeep, are important for attaining optimum ends in the FBD course of action.
It consists of the use of a fluidized bed to suspend and agitate particles, letting for economical drying and granulation.
Determine 8 reveals which the entrainment of fines for your demo at a superficial gas velocity of 1.six m/s commenced to enhance considerably since the granules grew to become floor dry. The entrained and collected fines have been person corn starch and lactose particles (Fig. 6f).
You can not use the fluid mattress dryer for lessening surplus humidity in organic solvents or substances that contains organic solvents.
The moist solids are lifted from the bottom and suspended in a very stream of air (fluidized point out). The hot gas Bordering each and every granule to fully dry them. Thus, supplies or granules are uniformly dried.
To measure entrainment, a fines collector was put in on one of many air retailers. The filter bag hooked up on the collector was taken out and weighed at 5-min intervals as well as the get more info fines gathered have been analyzed by scanning electron microscopy (Fig. 6f). Determine 7 reveals that the entrainment of fines was nominal at lower superficial gasoline velocities.
The “cost-free-body” in free of charge-physique diagram implies that the human body to become analyzed must be free of charge from your supports which can be physically holding it set up.
Wet granulation is normally accomplished in two phases: the granules are produced by agglomerating the assorted factors which has a binder Option in a high shear mixer and then the soaked granules are dried to stabilize the granule framework (3).
A blocked outlet filter may result in the force In the vessel to get more info increase, which could cause a mishap.
