ABSTRACT:
The specification discloses an apparatus and method for forming and projecting a continuous flow of frozen particles for the purpose of abrasive cleaning of substrate surfaces. The device utilizes a cryogenic fluid/dry air mixture that interacts with atomized water to form ice crystals. The crystals are projected through a blast nozzle to be directed at a substrate surface. The ice crystals, of a size range below one hundred micrometers, are produced within the apparatus just prior to the nozzle rather than being conveyed to the nozzle by a hose.
