ABSTRACT:
The invention provides an apparatus and method for continuously delivering ice particulates at high velocity onto a substrate for treating the surface of the substrate. The apparatus includes a refrigerated curved surface that is brought into contact with water to form a thin, substantially uniform, ice sheet on the surface. This ice sheet is of such thickness as to contain stresses so that the sheet is predisposed to fracture into particulates. A doctor-knife is mounted to intercept a leading edge of the ice sheet and to fragment the ice sheet to produce ice particulates. These ice particulates enter into at least one ice-receiving tube that extends substantially along the length of the doctor-knife. Once in the tube, the ice particulates are fluidized by a constant flow of air and are carried into a hose for delivery through an ice-blasting nozzle under pressure. The flow path for the ice particulates in the tube and the delivery hose has a substantially constant cross-sectional area, and flow surfaces are smooth to minimize the likelihood of blockages. Advantageously, the apparatus is able to function for extended periods of time without ice blockages occurring.
