Dry Ice Blasting for Food Processing Equipment

Food processors face a difficult cleaning equation: equipment must be sanitary, allergens must be controlled, downtime must stay short, and the cleaning method itself cannot introduce a new risk. Water-based cleaning often makes the problem worse — it pools in frames and bearings, drives corrosion, and creates microbial risk in dry production zones.

CO₂ and food safety

CO₂ is recognized by the U.S. FDA as Generally Recognized as Safe (GRAS) for use under cGMP. That makes dry ice blasting a strong fit for cleaning food contact and food zone equipment when performed by trained operators with appropriate procedures. The dry ice itself is consumable food-grade CO₂ pelletized on-site or delivered from a qualified supplier.

Where it fits inside a food plant

• Bakery ovens, pans, proofers, and conveyors
• Snack and cereal lines — extruders, dryers, coaters
• Confectionery — enrobers, cooling tunnels, depositors
• Dairy — fillers, cappers, blow molders, cleanrooms (where permitted)
• Beverage — bottle and can lines, labelers, palletizers
• Meat and poultry — smokehouses, ovens, packaging equipment (off-line)
• Allergen changeover cleaning between SKUs
• Dry mixing and milling — replacing problematic wet cleanouts

Why plants switch from wet cleaning

• No water in dry production zones — eliminates a major Listeria growth driver.
• Faster changeovers — clean in place, restart in minutes not hours.
• Less teardown — fewer guards removed, fewer torque sequences, fewer mistakes.
• No chemical residues to validate down to ppm.
• Better operator ergonomics than scraping and steaming.

Allergen changeovers

On lines that produce multiple SKUs containing one or more of the major allergens, changeover cleaning is the difference between a clean run and a recall. Dry ice blasting removes visible and invisible product residue without water and without chemicals — and it leaves the line ready to verify (ATP swab, allergen-specific swab) without an extended drying step.

What we typically do not clean with dry ice

We do not clean open product on open equipment. Production is either down or the equipment is isolated and product paths are protected. We follow the plant's SQF / BRC / FSSC procedures and document the work to the same standard.

Getting started

Most food plants start with a trial on a single bottleneck — usually a bakery oven, an extruder die, a snack drum, or a packaging head — and scale up as the time and quality savings become obvious. Call (866) 648-0030 or request a quote to schedule a walkthrough.
