Dry ice manufacturing starts with liquid carbon dioxide held under pressure 20 Bar (300 psi) in bulk storage vessels. To begin making dry ice, the liquid C02, is sent through an expansion valve into an empty chamber where under normal atmospheric pressure it flashes into C02 gas. This change from liquid to gas causes the temperature to drop quickly. About 43% of the gas will freeze into dry ice snow. The rest of the C02 gas, is released into the atmosphere or recovered to be used again. The dry ice snow is then collected in a chamber where it is compressed into blocks, or various sized pellets to meet customers requirements. The denser the dry ice is, the longer it will last, the easier it is to handle, and the better it will perform when blast cleaning.
