Residue buildup, protein deposits, and biofilms present persistent challenges in food production environments, often requiring time-consuming disassembly and extended equipment downtime. Traditional wet or chemical cleaning methods may introduce moisture, increase sanitation cycle time, and risk surface damage. Dry ice cleaning conveyor belts offers an alternative approach that supports cleaning-in-place procedures without water or abrasive media. Nu-Ice Blasting™ manufactures industrial dry ice blasting equipment designed for precision cleaning applications, including food processing dry ice blasting environments where hygiene compliance is critical. This clean in place dry ice food method enables the removal of stubborn food residue while maintaining sensitive surfaces and reducing operational disruption.
Dry ice blasting is a non-abrasive cleaning process that uses solid carbon dioxide (CO₂) pellets accelerated by compressed air to remove surface contaminants. The pellets are propelled through a blasting system and directed at the target surface, where they loosen and dislodge residues such as oils, proteins, and buildup. Upon impact, the dry ice pellets transition directly from solid to gas in a process known as sublimation. Because the CO₂ evaporates, the method produces no secondary blasting media waste beyond the removed contaminant. This makes dry ice blasting suitable for industrial environments where minimizing residue, moisture, and post-cleanup effort is essential.
Kinetic Impact
Dry ice pellets are accelerated using compressed air and delivered at high velocity to the cleaning surface. The mechanical impact helps loosen contaminants from the substrate without the use of abrasive materials.
Thermal Shock
Dry ice pellets are extremely cold. When they contact warmer surface contaminants, the rapid temperature change can cause the buildup to contract and weaken its bond with the underlying material.
Sublimation Expansion
Upon impact, the dry ice converts instantly from solid to gas. This rapid expansion assists in lifting and separating contaminants from the surface, supporting efficient removal without added moisture.
A dry ice blasting system consists of several integrated components that work together to deliver controlled cleaning performance. An air compressor supplies the compressed air required to accelerate dry ice pellets through the system. The dry ice hopper stores the solid CO₂ pellets prior to use. A metering system regulates the flow rate of pellets, allowing operators to control cleaning intensity based on application requirements. The blasting hose transports the pellets and air mixture to the nozzle, where the stream is directed onto the surface being cleaned. Each component functions together to provide precise, consistent delivery of dry ice media.
