Stainless Steel Vacuum Conveying Classification Equipment for Pharmaceutical Solid Material Handling

Integrating a vacuum conveying system, buffer silo, particle classification module, lifting mechanism, and other supporting components, this equipment operates through a fully automated workflow. During its operation, the vacuum conveyor creates negative pressure, which draws materials from the fluid bed silo through pipelines into the buffer silo—enabling stable, continuous material storage and feeding. Once the buffer silo reaches the pre-set material level, the discharge butterfly valve activates automatically, allowing materials to flow evenly into the classification chamber. Inside this chamber, materials are screened and classified by particle size; qualified products are then discharged into a dedicated collection hopper, completing the full automatic cycle of vacuum feeding, buffer storage, and high-precision particle classification.

As a newly developed product of our company, this unit incorporates advanced international technologies and is tailored to meet the technical requirements of domestic pharmaceutical solid preparation production. Boasting an integrated design that combines feeding, buffering, and classification functions, it effectively controls dust emissions and cross-contamination while streamlining the overall production process. Equipped with a lifting function, it can adapt to various process height requirements. The equipment features a compact, rationally designed structure with no sanitary dead corners, fully complying with GMP standards for pharmaceutical manufacturing.

Primarily designed 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 transports qualified granules from the granulator hopper to the blending bin, effectively suppressing dust, avoiding cross-contamination, reducing labor intensity, and enhancing production efficiency. Beyond the pharmaceutical sector, this equipment is also widely utilized in chemical, food, and other fine processing industries, delivering versatile performance for diverse material handling needs.
