    摘要: The invention provides an apparatus and method for partitioning continuously produced ice particulates and delivering them at a 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 harvesting blade 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 an inlet where they are fluidized and drawn into a manifold that extends substantially along the length of the harvesting blade. The manifold partitions the particulates into separate delivery tubes where they are ejected from nozzles to the workpiece. The manifold can be created to either evenly or unevenly distribute ice particulates to the delivery tubes. The flow of particulates through the nozzles can also be individually controlled by using a pressure regulator to control the amount of pressurized air entering the nozzles.
