A dry ice cleaning machine is a cleaning machine that propels dry ice particles onto the surface to be cleaned using high-pressure air. It utilizes the physical reaction of temperature difference to cause different materials to脱离 at varying rates.

When dry ice pellets at -78 degrees Celsius come into contact with a soiled surface, they cause a脆化explosion phenomenon, causing the dirt to contract and loosen. Subsequently, the dry ice pellets instantly vaporize and expand 800 times, generating a powerful stripping force that rapidly and thoroughly removes dirt from the surface, achieving a quick, efficient, safe, and energy-saving cleaning effect. The carbon dioxide used in dry ice cleaning comes from industrial waste gases and high-altitude air separation, and the cleaning process itself does not produce additional carbon dioxide.
