A screw press liquid separator includes a perforated screw cradle disposed within a housing. A screw is formed on a shaft within the screw cradle. A second portion of the screw extends to a discharge end and is completely surrounded by a compression portion of the cradle. A first portion of the shaft has a first diameter extending the length of the screw, and a second portion of the shaft within the compression portion and extending past the output end of the screw has a second larger diameter. A transition portion of the shaft tapers from the second diameter to the first diameter. Discharge guides extend from the discharge end of the housing. Discharge doors are pivotally mounted to the discharge end of the housing and are biased to close against the discharge end of the housing. Paddles radially extend from the shaft outside of the discharge doors.
