System and method for increased efficiency of screw presses

Abstract From the Canadian patent

An improved system and method for increasing the operational efficiency of screw-type presses which express or compress fluids from fibrous material. These improvements generally include improved means for compressing the fibrous material at its interface with both the hollow main shaft and the cylindrical outer housing of the press. Improved split worm flights having improved attaching means for each worm flight to the main shaft and collar therearound also contribute to improved efficiency. Further included is an improved means for draining the expressed liquids from the compression chamber radially inward into the hollow main shaft and radially outwardly through the outer housing wall of …
