Dry ice blast cleaning is a method of surface cleaning and dirt removal using dry ice particles (carbon dioxide solid). This technology is commonly used to clean equipment, machine parts, industrial facilities and other surfaces. It works by colliding high-speed jets of dry ice particles with dirt on the surface being cleaned, causing the dirt to freeze and fall off. Because dry ice will be converted directly into gas after spraying, it will not leave any residue, which makes dry ice cleaning technology particularly suitable for food equipment, electronic equipment and other occasions that have strict residue requirements. Additionally, since water is not required during dry ice cleaning, electrical hazards and equipment damage caused by liquids are avoided.
