PulseScrubber, launched by US-based Symetix, is said to be the industry's first continuous polishing system for softgel capsules.
Replacing traditional batch polishing systems, PulseScrubber extends Symetix's concept of a Continuous Softgel Finishing Line to maximise product quality and reduce labour while handling up to 900,000 capsules per hour.
Unlike batch polishing systems that require manual loading and unloading, PulseScrubber operates unattended - receiving, handling and discharging product continuously. Softgel capsules move down the length of the polishing system where absorption media above and below the product is energised by vibratory motion to gently polish the surfaces of the capsules.
PulseScrubber uses custom-made, FDA-accepted, low-lint absorption media manufactured from cellulosic fibres that are hydraulically entangled. Polishing the softgels removes oil from the surface of the capsule and creates a polished appearance.
If needed, manufacturers can batch-feed the bulk-to-bulk PulseScrubber immediately with a view to integrating it later integrate with other Symetix Continuous Softgel Finishing Line components to achieve fully automated, high-throughput softgel finishing line operation.
According to Symetix, PulseScrubber is easier to clear and clean than existing batch polishing systems. Product changeovers can be achieved in less than five minutes: simply snip the absorption media at the feed roll and discard, wipe down the vibratory bed, re-thread the absorption media and the polisher is ready for the next product run. The surfaces to be cleared and cleaned are all easy to reach and easy to observe, making the tasks more efficient to perform, the company says.
Based on Key Technology's Impulse electromagnetic vibratory conveyor, which Symetix has redesigned specifically for polishing softgels, PulseScrubber features an oil-free, solid-state electromagnetic drive, which is quiet and has no moving parts.
The compact PulseScrubber polisher handles 900,000 capsules per hour, and has a footprint of just 330mm wide by 2,300mm long. It is designed to meet FDA requirements and complies with GAMP 4 guidelines.
