Tablet Press Dedicated Granule Sizing Machine Vacuum Conveying Anti-Cross Contamination for OSD Production

This all-in-one processing machine integrates vacuum pneumatic feeding, material buffering storage, particle size classification and height adjustment functions into one compact standalone unit. When the system is running, the vacuum module creates stable negative pressure to extract powder and granular materials from fluid bed processing equipment. Materials travel through fully sealed pipelines and gradually accumulate in the buffer silo, ensuring steady and uninterrupted material supply for downstream operations. Once the material stock reaches the system’s preset capacity limit, the built-in sensor activates the automatic discharge valve. Materials are evenly guided into the internal classification chamber for precise dimensional screening and sorting. After grading, qualified particles that meet production standards are delivered to the designated collection hopper. The whole workflow completes vacuum feeding, material buffering and accurate particle sorting automatically, achieving fully unmanned material processing.

Engineered to suit high-standard solid production environments, this integrated conveying and classifying equipment adopts proven industrial technology optimized for pharmaceutical workshop conditions. It consolidates material transfer, temporary storage and particle screening into one streamlined process, replacing traditional multi-step manual workflows and improving overall production efficiency. The fully enclosed structural design effectively contains internal dust, eliminating cross-contamination risks between different production batches and optimizing workshop hygiene conditions. Equipped with an adjustable lifting mechanism, the unit allows flexible height calibration to achieve precise docking with various types of process machinery. All material contact surfaces feature seamless polished finishes with no hidden cleaning dead zones, fully meeting GMP hygiene requirements for pharmaceutical and food-grade manufacturing.

This vacuum conveying classifier acts as essential auxiliary equipment for closed-loop material handling in pharmaceutical production lines. It can be directly connected with fluid bed dryers, fluid bed granulators and other mainstream processing machines to realize fully enclosed automatic material transfer and particle grading across different production stations. The equipment greatly minimizes manual material handling, reduces dust pollution hazards, maintains consistent batch quality, and improves overall workshop throughput. Apart from pharmaceutical solid preparation production, this versatile unit also provides stable closed conveying and particle sorting solutions for bulk materials in chemical processing, food manufacturing and other fine industrial sectors.
