Advantages of dry ice cleaning machines
Release time:2023-02-20
As for the term “dry ice cleaning machine,” I’m sure many of you feel both familiar and unfamiliar with it. That’s because most people are at least somewhat acquainted with dry ice—after all, dry ice has a wide range of applications in daily life. Whether in the food service industry, wedding planning, pharmaceuticals, cold-chain logistics, e-commerce, or other sectors, many of you have probably heard of dry ice to some extent. However, when it comes to dry ice cleaning machines, many people remain unclear about their specific cleaning applications. So now, let’s have Meitengqi’s editor explain exactly what a dry ice cleaning machine is!
Although dry-ice blasting is still a relatively niche service in China, in several Western countries, it has been used for decades to clean oil and grime from surfaces in both civilian and industrial sectors. It was first applied to remove the outer coating of U.S. space shuttles and has since gradually expanded to cleaning equipment across various industries. Thanks to its excellent cleaning performance—quickly and efficiently removing surface contaminants without leaving any residue—over 80% of stain removal operations in these countries now rely on dry-ice blasting. In recent years, an increasing number of domestic Chinese companies have also begun adopting dry-ice blasting to clean stains from industrial molds.
The principle behind dry-ice cleaning is that compressed air accelerates dry-ice pellets, propelling them onto the surface of the object to be cleaned. Due to the extremely low temperature of dry ice (-78.5°C), any adhering contaminants are rapidly frozen and become brittle. At the same time, the dry-ice pellets penetrate into the brittle surface of the object. As the dry ice sublimates and its volume expands rapidly, it creates an explosive force from within, effectively dislodging and removing the contaminants from the surface of the object. The entire process relies entirely on physical properties, so there’s no need to worry about any damage or freezing of the equipment.
