The present invention relates to a system and a method of extracting liquid from a humid mass by compressing same. The system comprises a conduit of linear, circular or other shape through which the humid mass is displaced. The conduit is of rectangular cross-section, which cross-section can be constant or variable. Further, the conduit has perforated side walls along at least a liquid extraction working section of the conduit. The system further comprises elements which cause an axial pressure at the interior of the humid mass as well as a mechanism to displace at least one of the perforated side walls to convey the humid mass along the working section of the conduit in such a way as to generate between the interior surface of the perforated side walls and the humid mass a dynamic friction force which defines a pressure zone which is less than the axial pressure created by the pressure creating elements. This difference in pressure causes the liquid in the humid mass to flow out of the mass in a direction substantially transverse to the displacement direction of the humid mass and out through the perforated side walls of the conduit.
A system for extracting liquid from a humid mass, said system comprising a conduit having an inlet end for admitting a humid mass therein as a continuous stream, said conduit having perforations in at least a working section of said conduit, means to gradually and progressively create an axial pressure at the interior of said humid mass, said conduit having a movable side wall section having a surface area greater than the surface area of the remaining side wall section, means to impart continuous movement to said movable side wall so that said movable side wall is displaced axially along at least said working section of said conduit for displacing a humid mass axially along at least said working section of the conduit, said movable side wall section creating a dynamic friction force between the inner surface of the conduit and the humid mass to define a pressure zone which is inferior to said axial pressure whereby to establish a differential pressure through said mass to cause liquid therein to flow out of said mass transversely to the direction of travel of said mass and out of said conduit through said perforated section, said conduit having an outlet end through which there is discharged a continuous output of said humid mass containing only a small percentage of liquid therein.
A method of continuously extracting liquid from a humid mass by pressurization of said mass, said method comprising the steps of:
