For maximum process flexibility, Aeromatic-Fielder can supply a single Fluid Bed unit or Multi-Processor™ system with interchangeable modules or the NEW Flexstream™ fluid bed processor (patent pending) with granulation, drying and pellet coating (or tablet coating) 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.
