The first dry-ice blasting machine to be commercialized was a single-hose system. It was developed by Cold Jet, LLC in 1986, [ 7 ] [ 8 ] and uses a single hose to deliver air blasts and dry ice. Single-hose dry-ice blasters share many of the advantages of single-hose abrasive-blast systems.
As with all blasting technology, proper eyewear and hearing protection is recommended. Blasting machines reach levels of 115 db. Depending on the contaminants being cleaned, the level of protection varies. However, ice blasting is the safest blasting technology because of the lack of air pollutants consistent with other blasting technology.
In this type of blasting, air and dry ice are used. Surface contaminants are dislodged by the force of frozen carbon dioxide particles hitting at high velocity, and by slight shrinkage due to freezing which disrupts adhesion bonds. The dry ice sublimates, leaving no residue to clean up

Examples of materials removed include ink, glue, oil, paint, mold and rubber. Dry ice blasting can replace sandblasting, steam blasting, water blasting or solvent blasting. The primary environmental residue of dry ice blasting is the sublimed CO 2, thus making it a useful technique where residues from other blasting techniques are undesirable. [32]
Dry-ice blasting used to clean bakery equipment In pellet cleaning (" dry-ice blasting "), relatively large pellets of solid CO 2 are fired at the surface to be cleaned. These pellets impinge on the surface, mechanically dislodging contaminant particles.
