Waste powder recovery cyclone for pharmaceutical processes
Efficiently recover up to 99.9% of waste powder from oral solid dosage processes, reducing filter maintenance and minimizing material loss, while seamlessly integrating into your existing dust extraction systems.

Captures and Recovers Pharmaceutical Process Dust
The Hanningfield Uni-Dust Cyclone series is designed for effective powder recovery in pharmaceutical and nutraceutical manufacturing, ensuring efficient dust collection and reduced material loss. The cyclone works by utilizing vortex separation to capture waste powder from OSD processes like tableting and encapsulation. This system can be integrated with tablet presses and capsule filling machines, preventing filter blinding and extending the life of central dust extraction systems.
Uni-Dust cyclones can handle airflows ranging from 25 to 1200 m3/hr, making them adaptable to various production scales. Constructed from GMP-compliant stainless steel, they are suitable for use in ATEX Zone 0/20 environments. The equipment is maintenance-free with no moving parts, ensuring quiet operation and minimal operational costs.
The system is compatible with existing production lines through flexible hose or stainless steel pipework and can be customized with options like safe-change and level control for precise operational control. Full validation documentation and engineering support are available, ensuring the systems meet FDA and GMP standards.
