Fluid Bed Granulator
Fluid bed granulators combine mixing, granulating and drying in one fluidized chamber, building uniform, free-flowing granules from powders and liquid binders in a single continuous process.
FLP-Wurster Fluidized Bed Granulation Coater
Categories: Granulator and Extruder, Fluid Bed Granulator
All-in-One Mixing, Granulating, Coating, and Drying:
After the main material forms a fluidized bed at the bottom, granules are created with the aid of adhesive sprayed from the top nozzles in the granulating chamber. Subsequently, coating material is sprayed onto the granules from bottom or side nozzles within the chamber for effective coating.
- Input:
- Main ingredient as powder (for granulation) or granules and pellets (for coating), with adhesive or coating material in liquid form
- Output:
- Solid medium-sized granules with 3%–5% moisture content
- Type:
- Spray Fluidized Bed, Wet Granulation
- Additional Features:
- Mixing, Coating, Drying, Cooling
FL-Fluidized Bed Granulator
Categories: Granulator and Extruder, Fluid Bed Granulator
All-in-One Mixing, Granulating, and Drying:
Materials form a fluidized bed at the bottom, where granules are created in the granulation chamber with the help of spray nozzles dispensing binder. The hopper allows several raw materials to be added and mixed during the fluidization process.
- Input:
- Main ingredient as powder, adhesive in liquid form
- Output:
- Solid medium-sized granules with 3%–5% moisture content
- Type:
- Spray Fluidized Bed, Wet Granulation
- Additional Features:
- Mixing, Drying, Cooling
PGL-Fluidized Bed Spray Granulator
Categories: Granulator and Extruder, Fluid Bed Granulator
Combines Mixing, Granulating and Drying for High-Excipient Granulation:
Excipient-rich granulation finds an ideal match in this unit. Excipients in the hopper form a fluidized bed that acts as seeds or carriers, while the main material — typically a liquid extract making up a smaller proportion of the batch — is sprayed from above and merges at the bed's edge for granulation. This method is particularly suited to heat-sensitive materials.
- Input:
- Carrier materials in powder form, main material in liquid form
- Output:
- Solid medium-sized granules, 3%–5% moisture content
- Type:
- Spray Fluidized Bed, Wet Granulation
- Additional Features:
- Mixing, Drying, Cooling
Coating, Granulating and Spray-Granulating in One Chamber
The FLP Wurster fluidized bed granulation coater applies uniform coatings to particles suspended in air, the FL fluidized bed granulator builds granules from powder and binder in a single fluidized chamber, and the PGL fluidized bed spray granulator combines spray application with fluidization for controlled particle growth.
One-Step Mixing, Granulating and Drying
All three units combine mixing, granulating and drying in a single fluidized chamber, cutting processing steps versus separate wet-mix-then-dry lines. The Wurster configuration (FLP) is specifically suited to layered coating applications, such as taste-masking or controlled release. Spray granulation (PGL) suits building granules directly from liquid binder onto a fluidized powder bed.
