Wet Granulation
Wet Granulation covers SINOTHERMO's extrusion, fluid-bed and rapid-mixing granulators that bind fine powders into larger, free-flowing granules using liquid binder. The range spans tablet, instant-powder and engineered-particle applications across pharmaceutical, chemical and food processing lines.
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
SET-Screw Extruder Granulator
Categories: Granulator and Extruder
Wet Granulation with Screw Extrusion Process:
By utilizing an extrusion process, this wet-granulation machine leverages the self-viscosity of a solid-liquid dispersion to bond powder particles, producing granules of consistent shape and size. The screw-extrusion mechanism generates enough force to form pellets without always requiring a binder — particularly suitable for high-viscosity materials. Optional water cooling is available.
- Input:
- Solid-liquid mixture (predominantly solid)
- Output:
- Moist cylindrical granules
- Type:
- Extrusion Granulation, Wet Granulation
GHL-Wet Rapid Mixing Granulator
Categories: Granulator and Extruder
Cutting-Edge Wet Granulation Technology:
A paddle at the base swiftly mixes powders and sticky binders within a cylindrical bowl, while a rapid chopper on the side breaks the mixture into wet granules to prevent clumping. This fast process combines mixing and granule formation within minutes, and the Wet Rapid Mixing Granulator can provide heating or cooling as needed.
- Input:
- Main material in powder form, binding agent as paste
- Output:
- Solid, loose granules with approximately 15% moisture content
- Type:
- Mixing Granulation, Wet Granulation
- Additional Features:
- Mixing, Mild Crushing, Heating, 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
YK-Oscillating Granulator
Categories: Granulator and Extruder
Efficient, Versatile Oscillating Granulator:
The Oscillating Granulator uses a special back-and-forth motion to softly turn moist powder into even, round granules. Variable oscillation frequency and amplitude allow precise control of particle size and density, in a compact design with simple operation and low maintenance requirements.
- Input:
- Moist powder mixed with a binder
- Output:
- Wet cylindrical granules
- Type:
- Dry Granulation, Wet Granulation
- Additional Feature:
- Mixing
ZLB-Basket Granulator
Categories: Granulator and Extruder
Efficient Wet Extrusion Granulator:
Moist powder is pushed through a mesh by rotating blades during extrusion to form quality granules. The Basket Granulator offers steady granulation rates, visually appealing particles, an automated discharge process and high output levels.
- Input:
- Moist powder mixed with a binder
- Output:
- Wet cylindrical granules
- Type:
- Extrusion Granulation, Wet Granulation
- Additional Feature:
- Mixing
Binding Powders with Liquid to Form Granules
The FLP Wurster fluidized bed granulation coater, SET screw extruder granulator, GHL wet rapid mixing granulator, FL fluidized bed granulator, YK oscillating granulator and ZLB basket granulator all build granules using liquid binder to bind fine powders into larger, free-flowing particles.
Wet Granulation Process Paths
Rapid mixing (GHL) forms the wet mass, which extrusion (SET) or fluid-bed spraying (FL) then shapes and dries. Wurster coating (FLP) layers binder or coating material onto particles in a fluidized bed. Oscillating (YK) and basket (ZLB) granulators break a pre-formed wet mass into uniform granules.
