Claim:
A liquid extraction assembly for extracting liquid from a mass comprising: a housing having an inlet and an outlet; and a support supporting the housing and located below the housing; the housing further including a path between the inlet and the outlet; the housing being configured to have the mass forced into the inlet to move the mass from the inlet to the outlet; the housing including a pair of disc-shaped rotating screens adjacent the path and each defining opposite walls of the path; the pair of disc-shaped rotating screens each including a plurality of openings therethrough; wherein pressure from the mass forced into the inlet presses the mass against the pair of disc-shaped rotating screens to thereby force at least a portion of liquid in the mass to pass through the openings of the pair of disc-shaped rotating screens; wherein the inlet to the liquid extraction assembly is located below the outlet of the liquid extraction assembly; wherein the mass that moves from the inlet to the outlet does not pass through the pair of disc-shaped rotating screens; and wherein the inlet and the outlet are on a same side of the housing.
