With the help of a high-velocity spray of dry ice pellets, dry ice blasting eliminates impurities and coatings such as surface corrosion, grime, and paint. Because dry ice, the solid form of carbon dioxide, sublimates, this procedure, also known as “dry ice cleaning,” may be carried out without needing any medium.
Carbon dioxide in a solid form sublimates into a gas during the process of melting dry ice. This transformation occurs at -78.5 °C and 1 atm of standard atmospheric pressure. A dry ice storage container, air compressor, hose, nozzle, and blast pot make up the portable or movable equipment needed for dry ice cleaning.

Advantages of Dry Ice Blasting
Most agencies have given their approval to the clean, secure method of dry ice blasting. It won’t damage surfaces and doesn’t call for time-consuming scraping, harsh chemicals, or expensive clean-ups. Food-grade dry ice is a safe substance for commercial use and doesn’t create any additional waste streams, residues, or moisture. The pellets can clean holes and fractures without being stuck under challenging geometries because they sublimate.
There are several benefits to dry ice blasting. The medium is safe in the food sector, non-toxic, non-flammable, and non-abrasive. Unlike other techniques, the approach is nondestructive and minimises downtime for facilities and equipment.
How Does It Work?
Dry ice blasting uses three distinct shock and impact stages, each lasting a few milliseconds. The complete procedure, detailed below, includes a mixing stage that is added by abrasive ice blasting.
Thermal shock, a momentary mechanical force brought on by a quick temperature change, constitutes the first step. Thermal shock happens during dry ice blasting because the impurities or coatings on the surface freeze so quickly that they become brittle and break.
The second step, impact, occurs when the dry ice pellets quickly hit the target surface. Because of the thermal shock from stage one, the surface material is already brittle and broken during this contact, which transfers energy and momentum from the dry ice particles.
Expansion shock, the third and final stage of dry ice blasting, eliminates surface impurities or coatings. Expansion shock happens due to the dry ice pellets’ quick sublimation and heat transfer, which causes a rapid gas expansion. Dry ice cleaning physically eliminates the surface impurities or coatings when paired with the force of the CO2 pellets striking the target surface. There is also no media to clean up because the dry ice has sublimated.
