05.08.2019 WIP functionality for vacuum conveying offers healthier working environment

Piab Ltd, Loughborough, UK – a subsidiary of the Swedish parent company (see above) – reports that wet-in-place (WIP) functionality has recently been added to Piab’s piFLOW®p vacuum conveyors, thereby ensuring safer working conditions in food, chemical and pharmaceutical processing plants.

Water sprayed by the WIP nozzles wets any dust from materials left in the conveyors, stopping it from escaping into the air where it can be inhaled by processing staff during maintenance or cleaning procedures. By wetting potentially harmful residual material before the equipment is opened for cleaning, the spray nozzles ensure that any such dust stays wet-in-place until it can be safely removed.  

For maximum performance and coverage, and to ensure as much material as possible is captured as quickly as possible, up to three spray nozzles can be fitted to each conveyor. The configurable design of the piFLOW®p conveyor also allows simple retrofitting of WIP units, including extra air filters, in existing conveying systems. Piab’s sterile ultra low penetration air (ULPA, class U15-17) filters are said to provide greater filtration than high efficiency particulate air (HEPA) filters, and are offered as standard accessories for piFLOW®p.

Made from materials that comply with the US FDA and EU 1935/2004 regulations, Piab’s conveyors can be used to safely transport large volumes of powder/bulk materials, and their advanced technology will guarantee segregation-free conveying. Maximising the safety of the processing staff, piFLOW®p is available in ATEX dust and gas approved designs, in which all plastic or rubber parts, including filters and seals, are made of antistatic nitrile butadiene rubber (NBR).  WIP process in horizontal mixing systems: see EBS News for week of 29 July 2019.
