Abstract:
A filter system to extract juice containing oil from olives or other fruit pastes comprising a fruit paste, two fabric filter mats between which said fruit paste is spread and sandwiched, two filter plates between which said fabric filter mats and paste are sandwiched, said filter plates being of approximately the same size and shape as said fabric filter mats, said fabric filter mats having a porosity sufficient to allow the passage of said juice from said paste while excluding the solid materials contained within said paste, said filter plates having a conduit means comprising a plurality of slots, said slots having a depth equal to the thickness of said filter plate, said slots extending from within said filter plate to the outer edges of said filter plate, said slots being arranged so as to retain the structural integrity of said filter plate, a press means capable of raising the pressure within said fruit paste, whereby said fruit juice from said fruit paste flows through said fabric filter mats into said conduit means to the outer edges of said filter plates wherein the width of said slots and the thickness of said filter plate is selected to allow said fabric filter mat to bridge said slot under the pressure developed to form conduits for said fruit juice to flow to the outer edges of said filter plate.
