The productive heat and mass transfer within the fluidized mattress appreciably lessen the drying time when compared to other techniques. This not only improves efficiency but will also minimizes the potential risk of degradation or loss of unstable parts within the solution.
Greater drying temperatures is often potentially applied. However it is not possible in tray dryers and truck dryers.
The technique is additionally extremely Strength productive in contrast with those employing compressed air as no 3rd air provide is necessary. The FlexStream principle has the extra edge that no mechanical adjustment is important to switch between using the gear for a dryer, a granulator or even a coater.
The dryer is made of SS316, an austenitic chromium-nickel chrome steel containing a deliberate volume of molybdenum, escalating common corrosion. The construction with the Vertical fluidized bed dryer is shown while in the figure down below.
Once the velocity of the air is larger compared to the settling velocity of granules; and under the velocity for pneumatic conveying, the solids are buoyed up and become partly suspended during the fuel stream.
The principle behind a Fluidized Mattress Dryer revolves around the notion of fluidization. Fluidization is actually a procedure where solid particles are made to behave similar to a fluid by passing a fuel or liquid through them.
Granulating: Granulating is the strategy of creating granules by spraying aqueous or organic and natural solvents within the mixed powder.
This point out is referred to as fluidized point out. Each granule is thoroughly dried with the as, which envelops them.
A very hot filtered Air is handed from the Bowl to get dry. the granule particle suspends within the air right after getting lifted from the bottom aspect on the bowl with the help of the air stream.
Fresh air inlet, prefilter and warmth exchanger are linked serially to heat the air to your needed temperature.
FBD bowl loading: Inside of a pill production system, the whole operation of a Fluidized mattress drier commences with the loading of damp granular material in the granulator. The soaked granules being dried are put while in the removable bowl of a vertical FBD.
The Get hold of of scorching air with sound particles triggers the whole process of warmth transfer causing the dampness from solid particles to evaporate. The water vapor travels up here combined with the air stream and is particularly sooner or later vented out, abandoning dry particles. The air velocity, bed depth, and particle size and density strongly effects the performance of the procedure.
Whether The client’s requirement is for top shear mixing or granulation, GEA has a solution For each processing challenge and may help choose the technology that is read more certainly most fitted on your Pharma application.
The right option of distributor applied through the drying course of action guarantees even and steady fluidization.
