For maximum process flexibility, we can supply a single Aeronatic-Fielder™
Fluid Bed Granulator unit or Multi-Processor™ system with
interchangeable modules or the NEW Flexstream™ fluid bed processor (patent
pending) with granulator, dryer and pellet coater (or tablet coater) in
ONE processor.
We offer the following Fluid Bed Granulators from Aeromatic-Fielder™:
Pilot scale fluid bed granulator
The top spray granulator
agglomerates finer particles into larger, free flowing granulates in a one-pot
process. Ingredients are mixed and pre-heated by an upward flow of heated air.
Granulation occurs by spraying liquid into the fluidized powder. The granules
are subsequently dried with heated air. The top spray granulator can also be
used for top spray coating, layering from liquids, and instantizing.
Special features
- One pot process
- Selection of air
distributors
Spray Dryer Granulator The spray
dryer granulator transforms suspensions or solutions into dry, freeflowing,
dustless granules. A suspension or solution of the substance to be dried is
sprayed onto warm air, simultaneously drying and agglomerating the product.
Batch or continuous discharge is available in the continuous mode, the product
is discharged at a controlled rate to maintain an optimum bed height.
Special features
- Compact unit
- Easy scale-up
-
Batch or continuous discharge
Precision-Granulator™
A rotating high velocity
air stream is established in the central agglomeration tube. Particles are
picked up at the base of the tube and accelerated by the air stream. The
particles come into contact with liquid droplets produced from the spray nozzle
at the base of the tube \ the relative velocity of air, liquid droplets and
particles are high so wetting is efficient and drying begins almost
immediately. Most of the feed material is in the outer “holding area”, where
the gas velocity is very low. Attrition is greatly reduced. The gas humidity is
also low in the holding area so the material is dry not sticky.
Individual particles may make repeated cycles (typically from 10 to 1,000)
through the tube, allowing very large agglomerates to be built up.
