Dry ice cleaning machine is a physical cleaning equipment that uses dry ice particles (solid CO ₂) as a medium, accelerates spraying through high-pressure airflow, and achieves rapid removal of surface pollutants. Its core advantages are no residue, no wear, environmental protection and high efficiency. It is widely used in industrial manufacturing, mold maintenance, food and medicine and other fields.

core principle
Medium characteristics: Dry ice particles have a temperature of -78.5 ℃, sublimate instantly upon contact with heat (directly change from solid to gas, expand by about 800 times in volume), and have no liquid residue.
Triple mechanism of action:
Low temperature freezing: Dry ice causes pollutants (oil stains, carbon deposits, residual glue, coatings) to rapidly freeze and become brittle, losing adhesion.
Kinetic energy impact: High pressure airflow drives dry ice particles to collide with the surface at high speed, shattering brittle pollutants.
Sublimation expansion: Dry ice vaporizes instantly, causing a sudden increase in volume and producing a micro explosion effect, stripping pollutants and carrying them away with the airflow.
Core features: The cleaning process has no secondary waste (only pollutants need to be collected), does not damage the substrate, and does not require chemical agents.
