The FBD system finds considerable programs during the pharmaceutical business, especially in the drying and granulation of pharmaceutical powders and granules. Some typical applications include:
The fluidized bed guarantees uniform contact in between the drying medium plus the particles, leading to uniform drying through the entire mattress. This gets rid of the risk of above-drying or beneath-drying, leading to reliable product high quality.
Fluidization is the process wherein a granular substance in its original stable condition transitions right into a fluid-like state utilizing a fluid, which could be air or possibly a liquid. This basic principle underpins how a fluidized bed dryer features, proficiently drying out powdered or granular components.

Cartridge filter: stainless-steel filter cartridges are cleaned separately, making sure that a big proportion on the filter is often obtainable for continuous fluidization. In contrast to bag filters, This method can be cleaned-in-place.
The principle guiding a Fluidized Mattress Dryer revolves around the principle of fluidization. Fluidization is usually a procedure wherein sound particles are created to behave just like a fluid by passing a gas or liquid by way of them.
Granulating: Granulating is the tactic of making granules by spraying aqueous or organic and natural solvents within the mixed powder.
This condition is called read more fluidized state. Every granule is completely dried by the as, which envelops them.
Hence, very careful evaluation of each drying process is crucial to make certain the advantages could be capitalized, as well as the drawbacks can be managed or mitigated.
Once the gas or air velocity is amplified, it reaches some extent wherever the drag drive exerted on the particles overcomes their excess weight, leading to them to become suspended while more info in the fluidized bed.
Particle dimensions and distribution: The dimensions and distribution from the drug particles from the bed can have an effect on the flow habits as well as the uniformity of the final product.
• Inspection of FBD bag is performed for its integrity ahead of & after the usage and history in “FBD bag logbook”.
Immediate pelletizing: This method is also quite significant, With this API is in powder kind other products are straight transferred for the pellet without the addition of a starter core. API could be formulated to the matrix of pellets working with unique excipients, which has a qualified launch with the API.
If cleanliness is found satisfactory proceed for more activity if not repeat the cleaning ways.
