Stainless Steel Granule Sizing Machine with Vacuum Conveying for Pharma Tablet Press Feeding

This fully automated equipment integrates a vacuum conveying system, buffer silo, particle classifier, lifting mechanism, and other auxiliary components to deliver a seamless operational process. When in use, the vacuum conveyor generates negative pressure, which draws materials from the fluid bed silo through pipelines into the buffer silo—ensuring steady, uninterrupted material storage and feeding. Once the buffer silo reaches the pre-determined material level, the discharge butterfly valve triggers automatically, allowing materials to flow uniformly into the classification chamber. Within this chamber, materials are sorted and graded by particle size; qualified products are then discharged into a dedicated collection hopper, thus completing the full automatic cycle of vacuum feeding, buffer storage, and high-precision particle classification.

As a newly developed product by our company, this unit adopts advanced international technologies and is customized to meet the technical demands of domestic pharmaceutical solid preparation production. With an integrated design that combines feeding, buffering, and classification capabilities, it effectively controls dust dispersion and cross-contamination while optimizing the entire production process. Equipped with a lifting function, it can adapt to various process height requirements. The equipment boasts a compact, scientifically designed structure with no sanitary dead corners, fully adhering to GMP standards for pharmaceutical manufacturing.

Designed primarily for the transfer and feeding of solid materials in the pharmaceutical industry, this machine can be seamlessly integrated with fluid bed dryers and fluid bed granulators. It directly conveys qualified granules from the granulator hopper to the blending bin, effectively reducing dust, preventing cross-contamination, lowering labor intensity, and boosting production efficiency. In addition to the pharmaceutical industry, this versatile equipment is widely used in chemical, food, and other fine processing fields, providing reliable performance for a variety of solid material handling scenarios.
