Abstract
An apparatus for extracting a liquid from a workable mass of material includes a first screw section for transporting the material, a second screw section which applies a force on the material in a direction generally opposite that of the transport direction, and a second screw extruder at or near a liquid extraction location which provides a pinch point on the material. The pinch point substantially eliminates liquid flow countercurrent to the material transport direction.
