Multi Function Fluid Bed Granulator Coater 30-120kg Batch 316L GMP Design

When a single line must run granulating, pelletizing and film coating in the same campaign, changeover time is usually the bottleneck. The FLP-120 multi function fluid bed granulator coater removes that bottleneck by combining top spray granulating, tangential spray pelletizing, bottom spray coating and drying inside one closed process chamber. Because the laboratory FLP-1.5 and the production FLP-120 share the same chamber geometry and air distribution plate, a formulation validated on a few kilograms transfers directly to a 120 kg batch without re-developing the process.

Each fluid bed granulator coater in the range is built to GMP principles: sealed negative pressure operation, a polished product contact surface without dead corners, pneumatic filter bag lifting and a fan isolated in a separate sound enclosure that keeps measured noise below 75 dB. Process air volume, inlet temperature, spray rate and product temperature are driven from one electrical cabinet, so granule growth stays repeatable and the coating film deposited on every pellet has an even thickness. For buyers moving from tray drying or a High Shear Mixer route, the fluid bed granulator coater usually cuts a full granulate batch to a single shift operation and eliminates a separate drying room.

• One Chamber, Four Processes: the same fluid bed granulator coater runs top spray granulating, rotary or tangential pelletizing, bottom spray coating and final drying, so four machines are replaced by one installation and no wet granulate has to be transferred between rooms.
• 10-30 Mesh Granule Output: by adjusting spray rate and air volume the chamber produces the coarse 10-30 mesh granules required for instant drinks, condiments and effervescent formulations, with a narrow particle size spread.
• Taste Masking and Barrier Films: film, enteric, sustained release and controlled release coating of powders, granules and pellets, including moisture proof, anti-oxidation, heat insulation, colouring and isolation layers.
• Herbal Extract Spray Granulating: viscous traditional medicine extracts are atomized directly onto a powder bed, replacing the extract drying and crushing steps and reducing dust loss of active ingredients.
• Closed Negative Pressure Design: antistatic filter media and pneumatic bag shaking keep the working area dust free, prevent cross contamination between products and protect operators handling potent compounds.
• Repeatable Scale Up: identical bowl diameter to bed height ratio across the range means drying kinetics, spray distance and droplet residence time stay predictable when capacity is increased from pilot to production.

The fluid bed granulator coater is specified where a plant needs flexible small to medium batches with strict hygiene control. Typical duties include the following:

1. Tablet granule production in solid dosage plants, where the granules feed a rotary tablet press directly after drying.
2. Instant beverage, soup base and condiment granules requiring fast dissolution and uniform colour.
3. Pellet cores for capsule filling, coated for enteric release or sustained release profiles.
4. Traditional medicine extract granulation and coating, where sticky material previously blocked tray dryers.
5. Foodstuff and chemical powders needing moisture proof or anti-caking barrier films before packaging.

Because the same fluid bed granulator coater handles both the granulating and the coating stage, a contract manufacturer can schedule a granulating campaign in the morning and a coating campaign in the afternoon with a validated cleaning cycle in between, which shortens the production calendar and lowers labour cost per batch.

Can one fluid bed granulator coater really run granulating and coating? Yes. The chamber accepts four interchangeable beds: top spray for granulating, rotary or tangential for pelletizing, and bottom spray for film coating. The spray nozzle position and the air distribution plate are changed in minutes, and the recipe for each mode is stored separately in the control cabinet.

What batch size does the 1500 mm unit handle? The FLP-120 handles 30 kg to 120 kg per batch depending on bulk density. For lighter powders the practical upper limit is set by the 22 kW fan rather than by the bowl volume, so a bulk density test on your material is recommended before ordering.

Is the machine GMP compliant? The fluid bed granulator coater is designed and built to GMP requirements: sealed negative pressure operation, 316L contact parts, antistatic filter media, no exposed dead corners and full documentation including material certificates, IQ OQ templates and a cleaning validation guide.

How long does a granulating batch take? A typical dry mix, spray and drying cycle for a tablet granule runs 45 to 75 minutes, with the drying phase usually 20 to 30 minutes. Coating cycles depend on film weight gain and normally run 60 to 120 minutes.

The fluid bed granulator coater ships in export grade plywood cases with the chamber protected by a desiccant bag and the electrical cabinet packed separately. A factory acceptance test with your material sample, dimensional report, material certificates and a 12 month warranty on mechanical parts are included. Commissioning support, operator training and spare filter bags, nozzles and seals are available for the full service life of the equipment.
