Anti-Cross Contamination Granule Sizing Machine Vacuum Conveying for Pharma Production Line Tablet Press

This automated material processing unit combines pneumatic vacuum conveying, buffer storage, particle screening and height adjustment functions into a single standalone system. During normal operation, sustained negative pressure generated by the vacuum unit pulls powdered and granular materials out of fluid bed processing devices. Through fully sealed pipeline routes, raw materials are steadily delivered and accumulated inside the buffer silo to maintain continuous and consistent material supply. When the stored material volume reaches the preset threshold, the sensor triggers the automatic discharge valve. Materials flow uniformly into the internal classification chamber for accurate size screening. After layered sorting, particles that meet production specifications are delivered into the dedicated collecting hopper. The entire operational flow covers pneumatic feeding, buffer storage and precision grading, realizing full-process unmanned material treatment.

Developed to adapt to high-standard solid preparation production environments, this integrated conveying and grading machine adopts mature industrial process design tailored for pharmaceutical workshop requirements. It merges material transportation, temporary storage and particle screening functions to simplify traditional multi-step production procedures. The integrated structural layout effectively contains internal dust and avoids cross-contamination between different production batches, greatly improving workshop sanitation level. Equipped with a height-adjustable lifting structure, the equipment supports flexible height matching and smooth docking with various types of process machinery. All material contact surfaces adopt seamless polishing treatment without cleaning dead ends, fully satisfying GMP hygiene standards required for pharmaceutical and food-grade manufacturing.

This vacuum conveying classifier serves as key auxiliary equipment for closed-loop material processing in pharmaceutical production lines. It supports direct connection with fluid bed dryers, fluid bed granulators and other mainstream processing machines, achieving fully enclosed automatic transfer and grading of granules across different working stations. It drastically reduces manual material handling, lowers dust pollution risks and ensures stable batch-to-batch consistency while boosting overall workshop production capacity. Beyond pharmaceutical solid preparation, the equipment also delivers reliable performance for closed conveying and particle sorting of bulk solids in chemical processing, food manufacturing and other fine processing industries.
