ABSTRACT

Dry ice is made from liquid carbon dioxide, a recycled byproduct of several manufacturing processes. During the blasting process the dry ice sublimates to carbon dioxide gas, just like that exhaled by humans and found naturally in our atmosphere. Using dry ice is safe for employees and the environment. Dry Ice blasting uses extruded dry ice pellets, roughly the size of a grain of rice. The pellets are made on a dry ice extrusion machine called a "pelletizer" or "nuggetizer". The pellets can be produced, stored in sealed insulated containers, shipped, and used for blasting several days after they are produced.
