The dry - ice cleaning machine sprays solid dry - ice pellets (0.3mm/1mm/3mm) onto the surface at high speed to generate impact micro - explosions. That is, the dry - ice pellets impact the surface at high speed and burst into gas instantaneously, creating micro - explosions. When the dry ice impacts the surface instantaneously, the stains contract due to the cold, making them easier to peel off from the surface. As dry ice sublimates, its volume expands approximately 800 times. The powerful air wave blows away the stains, achieving a dry and residue - free cleaning effect.
