ABSTRACT:
A method and apparatus are disclosed for automatically cleaning extrusion screens in finishing machines of a type having a generally cylindrical perforated screen arranged in a housing, juice or the like laden with solids being introduced into the interior of the screen and urged against the screen by a screw element, paddle assembly, or the like to cause the juice to flow through the screen with the solids being retained on the screen. The cleaning method and apparatus comprise a cleaning unit with a plurality of spray nozzles arranged about the screen, the cleaning unit being moved back and forth along the screen by a reversing motor additionally controlled by suitable limit switches. The method and apparatus of the invention are preferably adapted for causing relatively increased cleaning action adjacent a solids outlet end of the screen to better remove larger amounts of juice solids or pomace deposited on that portion of the screen.
