Optimizing Your Production TCO

Filling Precision

  • Eliminates Weight Variation (RSD < 2.0%).
  • Guarantees Uniform Content of Active Ingredients (API).
  • Supports high-speed encapsulation (up to 150,000 caps/hr).

Process Stability

  • Reduced moisture sensitivity due to optimized surface area.
  • Minimal segregation during long-duration mixing cycles.
  • Prevents “capping” and “lamination” in tablet pressing.

Economic Yield

  • Reduction in raw material waste by 15-20%.
  • Extended lifespan of punch dies and dosing disks.
  • Faster cleanup times between batches.

Technical Insight: The Balance of Porosity and Strength

Our 40-mesh granules are not merely crushed material. They are engineered via Fluid-Bed Spray Agglomeration. This creates a porous internal structure that facilitates instantaneous disintegration upon contact with gastric fluids, while maintaining the external hardness required to survive the mechanical stress of industrial blenders and transport systems.
