A continuous process for extracting olive oil from olives comprises a milling apparatus 420, a malaxer 440 and a separator 460. The milling apparatus comprising a means, e.g. screw auger 426 for moving the olives through and at least one blade 428 for shearing the olives. The malaxer 440 is a continuous malaxer comprising a means, e.g. screw auger 446, for moving the sheared olive paste through the malaxer to the separator and also for kneading the paste as it passes through. The separator 460, which may be a vertical screw press, separates the liquids from the solid pomace. The liquid may be pumped to a sedimentation tank for the separation of oil from water. The mill and malaxer may be supplied with an inert gas to control the level of oxygen and reduce oxidation. The milling apparatus may comprise a perforated plate associated with each blade |
