Abstract

Liquid extractor press from pulp or vegetable substances, characterized by comprising a pre-press working at a relatively low pressure, and a press-end fed by said pre-press and working at a higher pressure relatively to the working pressure of the referred to pre-press; said pre-press comprising an inlet hopper for the pulp to be pressed, a plurality of screw-threaded shanks rotatably mounted on mutually and substantially parallel shafts each having spirally disposed fluted protrusions which are inserted between the similar protrusions of adjacent screw-shafts , a perforated strainer sleeve that closely surrounds the said screw shanks and their protrusions with a minimum clearance between the said protrusions and said strainer sleeve, an outer housing surrounding said screw shanks and said perforated strainer sleeve, and drive means for the said screw shanks, while the end press comprises, or at least a rotating screw shank with spirally spiral protrusions, a perforated strainer sleeve having a substantially cylindrical-circular cross-section and closely surrounding said shank- screw and its protruding spirals with a me minimum play between said projections and said strainer sleeve, an outer housing surrounding the above-mentioned screw shanks and perforated strainer sleeve with an interspace between them, driving means for said shank-screw, a fluid outlet for the fluid withdrawn from said pulp and connected to the expressed interspace between said strainer sleeve and said outer housing, and an outlet for the pressed pulp connected to the interior of said perforated strainer sleeve.
