A food processing plant sent stainless steel conveyor chain links contaminated with baked-on food residue and biofilm to the Keertek test center. Unlike conventional wet cleaning, Keertek applied an ICE-JET dry ice blasting solution — zero moisture, zero chemicals — delivering results that passed FDA and 3A sanitary standards in a single test.
The chain links, used in a snack-food baking line, carried carbonized oil, sugar residue, and early-stage biofilm deep inside pin joints and link crevices — areas that spray washing could never reach, and where residual moisture from wet cleaning could actually promote new bacterial growth. Keertek’s test center deployed the ICE-JET dry ice blasting system, propelling micron-sized CO₂ pellets at supersonic speed onto the part surfaces. The thermal shock and micro-explosion effect upon impact instantly stripped contaminants, while the dry ice sublimated into gas, leaving zero residue — not a single drop of water entered the process.
Post-cleaning microbiological swab tests returned ATP levels far below the 3A sanitary threshold. Parts emerged bone-dry and ready for immediate reinstallation, requiring no drying downtime whatsoever. The food processor purchased a Keertek ICE-JET dry ice cleaning unit for weekly sanitation maintenance, replacing the labor-intensive manual scrubbing routine and reducing sanitation downtime by over 70%.
