The granulation equipment compresses dry powder raw materials by roll compression in the form of plates, which are sized into flakes.
It provides an optimum solution for water- or heat-sensitive raw materials because addition of a solution and a drying process are eliminated, and significantly reduces cost by eliminating these processes in the manufacturing method.
By adopting DPS rolls and side seals developed by Freund, uncompressed powder can be minimized with a uniform pressure distribution.
Due to the optional deaerating mechanism, powder with a large specific volume can also be processed.
FEATURE
- Enables forming with uniform pressure distribution, with an extremely small amount of uncompressed powder
In addition, the uniformity of pressure distribution and the homogeneity of granules are further improved by selecting the compression rolls and screw according to powder characteristics. - Supports all powder properties with the adoption of a special screw
- The processes from feeding raw materials, forming and sizing are vertically configured, so that the installation space is small, and washing is easy.
- Supports various granulated products by freely adjusting the hydraulic cylinder
- It provides an optimum solution for water- or heat-sensitive raw materials because addition of a solution and a drying process are eliminated in the manufacturing method.
- Small in the number of parts, excellent in workability, and GMP-compliant
- Enables forming with uniform pressure distribution, with an extremely small amount of uncompressed powder
There are three selectable types of rolls.
By selecting the compression rolls and screws according to powder characteristics, the yield and production capacity are improved while the quality of granules (pressure distribution) is maintained.
DPS rolls (standard)
Granules homogeneous in pressure distribution can be obtained by suppressing unevenness in hardness between the center and ends of the rolls.
S rolls
Excellent at granulating easy-to-adhere raw materials (Kampo medicines, etc.), raw materials to which no lubricants can be added, powder raw materials that are hard to be supplied in between rolls.
DP rolls
Excellent at granulating powder raw materials that are excessively supplied in between DPS rolls if used, and easy-to-adhere raw materials.
There are two selectable types of screws (A or B).
A type
The blades are double-wound. It is suitable for powders with a large specific volume.
B type
The blade is a single-wound. It is suitable for powder with a small specific volume; This standard-type screw is ideal for most powders.
*Please contact us for the degassing unit (straight type screw).
There are four selectable types of screens at the most.
Standard wire mesh
General plain weave mesh screen
・Material properties: brittle, hard
・Adaptation: Φ5 to 30 mesh
Standard perforated mesh
Contact risk reduction screen
・General round hole opening
・Material properties: brittle
・Adaptation Φ: 1.0 to 3.0 mesh
・Minimum opening: 1.5 mm
・Material: SUS304, SUS316L
Square wire mesh
The processing speed-oriented screen
It reduces retention in the sizing machine to 1/5*.
・Raw material properties: hard
・Adaptation: Equivalent to 14, 16 mesh of standard wire mesh (opening)
・Minimum opening: 1.0 mm
・Material: SUS304
GGP
Durable screen
Not only does it reduce contact risk, but it also increases throughput compared to standard punching.
・Amount processed by sizing machine: same as standard wire mesh
・Material properties: brittle, hard
・Adaptation Φ: 1.0 to 3.0 mesh
・Minimum opening: 1.5mm
・Material: SUS304, SUS316L
*Processing capacity varies depending on raw material characteristics and conditions.
