COULD THIS BE THE MOST SUSTAINABLE CLEANING METHOD AVAILABLE TO THE FOOD AND BEVERAGE INDUSTRY EVER?

Dry ice blasting is the most sustainable cleaning method available to the food and beverage industry ever, believes Matthew Prestidge, Industrial Hygiene Advisor for Presco Environmental. “It always amazes me how we can completely sanitise a surface to meet food production standards, yet use no chemicals at all!”

Presco Environmental, a family-owned business based in Taranaki that provide industrial cleaning services to the NZ food and beverage industry, are now offering this innovative cleaning technology which not only helps food production factories in their visions towards a more sustainable future, but is a solution in places that were previously very difficult to clean.

Dry ice blasting is exactly as the name says; cleaning by blasting dry ice. Small rice-sized pellets of dry ice (CO₂) are blasted with compressed air at the dirty surface. The extremely low temperatures of the dry ice (-78C˚) kills any bacteria and freezes the soil, which becomes brittle and flakes off. The pellets sublimate on impact, leaving only the dislodged soil to sweep up off the floor! Being non-abrasive, dry ice leaves the surface underneath the soil in perfect condition.

Dry ice blasting is a “net-zero” carbon footprint cleaning methodology- recycling the world’s number 1 waste product (CO₂).

Aside from sustainability, dry ice blasting comes with a slew of other benefits, says Matthew. “CO₂ is a non-conductive gas so is perfect for electrical plants; it can clean around wiring and sensors while they are still live! No water means it’s perfect for dry environments like powder plants as production can resume immediately after the job. No time is wasted waiting for the plant to cool down, dismantling and reassembling or waiting for it to dry out.”

Dry ice blasting is used widely overseas but is relatively new to us in NZ. It is a popular cleaning method in the automotive and restoration industries. Seeing its sanitation properties, Presco Environmental are excited to bring the technology to the food processing industry.

Matthew says in the 3 years Presco Environmental have been providing the service, they are seeing more and more plants are looking to dry ice blasting as a sustainable cleaning solution to a difficult cleaning problem. “It’s so satisfying to see the amazed look on a customer’s face when they see what [dry ice blasting] can do. We recently did a job at a big baking company for the second year in a row; cleaning baked on carbon build-up out of their huge industrial ovens and off their conveyors. Previously they had had to shut down for a couple of days while cleaners wiped over all the equipment and then did a chemical clean. They would then have to run a couple of shifts for all the residual chemical and carbon mix to settle. Dry ice blasting has saved them 3-4 days of production time!”

Presco Environmental have experienced and trained dry ice blasting technicians that understand the critical hygiene requirements of the food processing industry and service NZ-wide. If you have a difficult cleaning situation, would like to clean without using chemicals or water or would just like to find out more about this amazing technology, call the Presco team on 0800 PRESCO (773726) or visit https://prescoenvironmental.co.nz/services/dry-ice-blasting/ .
