Dust-Tight Deduster with Metal Detectors

Pharma Technology Inc. (PTI) introduces a containment (C) version of its completely modular PharmaFlex iSeries 750 dust-tight deduster combined with advanced metal detectors.

The advancements of the new C version build on the PharmaFlex iSeries 750 dust-tight deduster that features a patented air jet and vacuum concept: circumferential dust extraction on the spiral periphery combines with central air jets for efficient dust removal. In parallel tests where tablets were weighed before and after dedusting, the PharmaFlex iSeries removes up to 40% more dust compared to traditional stainless steel spirals with dust extraction through a central tube.

Additional features of the new containment version of the PharmaFlex iSeries 750 includes:

• OEB 3 rated dispenser for metal detector test pieces
• Clip & cut collection of metal detector rejects and sampled tablets
• Doubling up of all flexible connections for tablet inlet, dust extraction and tablet outlet, with continuous PE liner and Clip & cut secure double clips at each end for contained separation and offline cleaning
• Continuous negative pressure monitoring during operation shuts down pinch valves in case of sudden overpressure
• Optional HEPA filter on air inlet acts as double safety in case of sudden overpressure
• Automated pinch valves at the air inlet port for unit isolation
• Containment features allow operation to OEB 3 during connection, operation, disconnection and reassembly
• The PharmaFlex iSeries can be used in tandem with the iSeries automated IPC tester also rated for OEB 3 testing of weight, thickness, and hardness with feedback to the tablet press

The PharmaFlex iSeries dedusters are comprised of segmented transparent Tritan polymer spirals allowing for 360° product viewing – making external windows with seals or fastening mechanisms unnecessary. The robust Tritan material is resistant to 6-ft drops, 85°C hot water, common alkaline detergents, and prolonged alcohol exposure.

All contact parts are contained within the deduster tower, resulting in complete segregation of the dedusting and mechanical areas, with no dust extraction channel through the mechanical base. Wide inlet and outlet chutes allow for increased tablet output, and a patented round throughput chute through the metal detector head provides enhanced detection sensitivity.
