ABSTRACT:
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 worms 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 fluids from the compression chamber radially inward into the hollow main shaft and radially outwardly through the outer housing wall of the compression chamber. In addition to improved radially outward drainage, improved wedge-shaped screen bars in the cylindrical outer housing walls eliminate the need for breaker bars which are otherwise necessary to reduce the spiraling effect of this fibrous material during compression. The improved method relates to intermittent compression relaxation of the fibrous material, followed by aeration of the compression chamber and fibrous material with a compressed gas.
