Abstract

A liquid extraction assembly for extracting liquid from a mass comprising a housing having an inlet and an outlet. The housing further includes a path between the inlet and the outlet. The housing is configured to have the mass forced into the inlet to move the mass from the inlet to the outlet. The housing includes two substantially parallel rotating screens rotating side by side and apart from one another, with the path extending between the screens. Each screen defines one wall of the path. Each rotating screen includes a plurality of non-circular openings located at the path. Pressure from mass forced into the input presses the mass against the non-circular openings of the rotating screens to thereby force at least a portion of liquid in the mass to pass through the non-circular openings of the rotating screens.

Claims

exact text as granted — not AI-modified
1 . A liquid extraction assembly for extracting liquid from a mass comprising:
 a housing having an inlet and an outlet;   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 two substantially parallel rotating screens rotating side by side and apart from one another, with the path extending between the screens, each screen defining one wall of the path;   each rotating screen including a plurality of non-circular openings located at the path;   wherein pressure from mass forced into the input presses the mass against the non-circular openings of the rotating screens to thereby force at least a portion of liquid in the mass to pass through the non-circular openings of the rotating screens.   
     
     
         2 . The liquid extraction assembly of  claim 1 , wherein:
 the path is substantially circular.   
     
     
         3 . The liquid extraction assembly of  claim 1 , further including:
 a motor for rotating the rotating screens.   
     
     
         4 . The liquid extraction assembly of  claim 3 , further including:
 a shaft assembly extending from the motor to the rotating screens;   the shaft assembly having a right angled portion.   
     
     
         5 . The liquid extraction assembly of  claim 1 , wherein:
 the plurality of non-circular openings comprises a plurality of parallel elongated non-circular slots.   
     
     
         6 . The liquid extraction assembly of  claim 5 , wherein:
 each rotating screen is circular; and   at least one of the elongated non-circular slots extends from a first point on the circumference of one of the rotating screens to a second point on the circumference of the one of the rotating screens.   
     
     
         7 . A method of extracting liquid from a mass comprising:
 providing a housing having an inlet and an outlet, with the housing further including a path between the inlet and the outlet, the housing further including two substantially parallel rotating screens rotating side by side and apart from one another, with the path extending between the screens, each rotating screen being adjacent the path and defining one, wall of the path, each rotating screen including a plurality of non-circular openings therethrough, the non-circular openings being located at the path;   forcing the mass into the inlet;   rotating the screen;   abutting the mass in the path against the non-circular openings of the screen; and   forcing at least a portion of liquid in the mass through the non-circular openings in the rotating screens.   
     
     
         8 . The method of  claim 7 , wherein:
 the path is substantially circular.   
     
     
         9 . The method of  claim 7 , further including:
 providing a motor for rotating the rotating screens; and   rotating the rotating screens with the motor.   
     
     
         10 . The method of  claim 9 , further including:
 providing a shaft assembly extending from the motor to the rotating screens; and   providing the shaft assembly with a right angled portion.   
     
     
         11 . A system for extracting liquid from a mass comprising:
 a portable platform having an upper surface;   a system mass input;   a liquid extraction assembly on the upper surface; and   piping between the system mass input and the liquid extraction assembly;   wherein the system is configured to have mass inputted into the system mass input, transport the mass to the liquid extraction assembly; and   wherein pressure from mass forced into the liquid extraction assembly forces at least a portion of liquid in the mass to exit the mass.   
     
     
         12 . The system for extracting liquid from a mass of  claim 11 , wherein:
 the upper surface of the portable platform is less than 72 square feet.   
     
     
         13 . The system for extracting liquid from a mass of  claim 11 , wherein:
 the liquid extraction assembly comprises at least one housing having an inlet and an outlet;   the at least one housing further including a path between the inlet and the outlet;   the at least housing being configured to have the mass forced into the inlet to move the mass from the inlet to the outlet;   the at least one housing including at least one rotating screen adjacent the path and defining one wall of the path;   the at least one rotating screen including a plurality of openings therethrough;   wherein pressure from mass forced into the input presses the mass against the at least one rotating screen to thereby force at least a portion of liquid in the mass to pass through the openings of the at least one rotating screen.   
     
     
         14 . The system for extracting liquid from a mass of  claim 13 , wherein:
 the at least one housing comprises two housings.   
     
     
         15 . The system for extracting liquid from a mass of  claim 14 , wherein:
 a single motor is positioned between the housings for driving the rotating screens.   
     
     
         16 . The system for extracting liquid from a mass of  claim 15 , further including:
 a shaft assembly extending from the motor to the rotating screens;   the shaft assembly having a pair of right angled portions.   
     
     
         17 . The system for extracting liquid from a mass of  claim 13 , wherein:
 the openings comprise a plurality of non-circular openings located at the path.   
     
     
         18 . The system for extracting liquid from a mass of  claim 17 , wherein:
 the plurality of non-circular openings comprises a plurality of parallel elongated non-circular slots.   
     
     
         19 . The liquid extraction assembly of  claim 5 , wherein:
