Abstract: An improved rotating basket extractor is provided having improved discharge means comprising a hopper section having a solid material entry and solid material exit end. The cross sectional area of the solid material entry end is smaller than the exit end so as to help prevent the agglomeration of solid material in the discharge hopper as it exits from the rotating baskets to a dual screw conveyor for subsequent travel to a discharge chute. The discharge hopper and the housing for the dual screw conveyor comprise slot means to provide for additional drainage of miscella therethrough. Additionally, the axially disposed rotatable shaft, supporting the rotating baskets, is journalled in a thrust bearing provided contiguous to the flooring substrate. Location of the thrust bearing there helps to minimize bearing contamination and corrosion.

Abstract: A sleeve is provided for a mechanical screw press for expressing liquid from liquid-containing grains and seeds. The sleeve of the present invention is formed with drainage apertures located between longitudinally extending runner portions and includes slots formed in the runner portions adjacent to the drainage apertures. With the use of such slots, uniform screen bars can be used throughout the sleeve and main cage of the screw press.
