ABSTRACT:
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.
