A system for improving the operating efficiency of screw presses which express fluids from fibrous material. This system includes a plurality of worm sections and collars and a hollow main shaft. Fluids are allowed to pass into the hollow shaft through one or more screen bar sections, fitted over the collars. The area of the collar housing beneath the screen bars is generally funnel-shaped toward the longitudinal rotational axis of the shaft, having a drain opening near the apex of the funnel configuration to allow expressed fluids to exit into the hollow drive shaft or into a conduit therein. The worm flights may include hardened wear resistant inserts in the outer peripheral surface which may be integrally cast into the worm section. The worm sections which mate to form a single divided worm may be identical and therefore reversible to reduce production and inventory costs. As part of this system for improving efficiency, these dividable worms are now removable separately through the side of the press after the cage has been removed.

High pressure mechanical screw press system for removal of fluids from organic materials such as sugar cane, meal, nuts, bagasse, and other materials including a hollow main shaft, at least one pressure chamber, feed worm with a plurality of worms and collars arranged on the hollow main shaft, said worms having flights thereon, securing means for securing the worms and collars on the hollow main shaft, the worm flights, rotationally driven by the hollow main shaft to press fluids from the material within at least one pressure chamber, said system comprising: said hollow main shaft having a relatively large conduit therethrough and a relatively thin wall thickness, said hollow main shaft having a plurality of conduit means through said thin wall; an inwardly directed means for removing at least some of the pressed fluids out of the pressure chamber; said collars including said inwardly directed means; said collars and said inwardly directed means aligned with said conduit means to provide direct fluid drainage into said hollow main shaft; said collars connected directly onto and about said hollow main shaft to provide structural support for said hollow main shaft with the relative large conduit.
