FOOD & BEVERAGE INDUSTRY
Everyday food industry deals with the challenge of maintaining hygiene standards and cleanliness. The equipment utilized in this industry needs to be perfectly clean in order to maximize the production capacity and to reduce the chances of accidents occurring due to poor maintenance.
Food processing and packaging equipment gets dirty with grease, wax, proteins, seasonings, crumbs, glue and other buildup. This prevents the equipment from operating at peak efficiency.
Unfortunately, traditional methods like wire brushes, sand blasting, solvents and high pressure are time consuming, ineffective and usually involve significant amounts of water and resulting waste.
The cleaning method Dry Ice Blasting, which uses harmless dry ice pellets, is preferred at many levels in the food and beverage industry. Dry ice cleaning is an approved method of cleaning by the CFIA.
As mentioned, the Canadian Food Inspection Agency (CFIA) accepts food grade dry ice for use as a general cleaner. It also meets United States Department of Agriculture (USDA) guidelines. Dry ice blast cleaning finds numerous applications within the food industry including:
- Production equipment – ex: ovens, bake trays, slicers, food moulds, fryers
- Packaging equipment - ex: folders, gluers, palletizers, baggers
- Production environment - ex: walls, floors, piping, exhaust fans
- Electrical components - ex: motors, switches, panels, wiring
- Inaccessible or tightly spaced areas - ex: bulbous welds, conveyor components, crevices, dead ends
Benefits of dry ice cleaning in the Food/Beverage Industry
- Waterless process – dry ice instantly vaporizes during the blast cleaning process, leaving behind no residues. This waterless cleaning procedure is ideal for industries that rely on dry cleaning methods (ex: bakeries) and for other sensitive cleaning applications (ex: electrical equipment).
- Non-abrasive – no abrasive cleaning agents are required, thus avoiding damage to equipment surface integrity (ex: pitting, corrosion).
- Deep cleaning – pressurized dry ice effectively cleans various nooks and crannies that are difficult to reach using brushes or other traditional cleaning methods.
- Microorganism removal – dry ice cleaning is effective for the removal of Salmonella, E. coli and Listeria from stainless steel, ceramic tile and food grade plastic surfaces.
- Costs savings – reduced labour and other sanitation associated costs (ex: chemicals, water savings).
- Clean hot – equipment surfaces are blast cleaned while still warm, which prevents prolonged shutdown times.
- On-site cleaning – mobile blast cleaning machinery eliminates the need for targetequipment to be moved to designated cleaning areas.
- Non-hazardous – the dry ice blast cleaning procedure requires no toxic cleaning chemicals, solvents, sanitizers or detergents.
