Abstract
A scraper nozzle which provides a high pressure, uniform sheet of water. The nozzle is preferably used in the upstream portion of the prewash zone of a warewasher. Wares, such as dishes, are contacted by the sheet of water and the materials on the dishes are scraped off. The nozzle comprises a planar surface and an arcuate surface. The arcuate surface terminates in a discharge edge which is characterized by a plurality of protuberances. The water flows across the discharge edge and forms the uniform sheet of water.
