Abstract
Abstract An apparatus for juicing fruit having a rind and varying in hardness and size, and performing, generally the steps of supporting a said fruit, cutting an opening through the rind at one side thereof, then confining the said fruit and applying external pressure thereto thereby extruding a core through the opening cut through the rind and delivering the juice from said fruit via said opening and through said extruded core; and including a hydraulically operated and hydraulically responsive mechanism involving a ram that moves the supported whole fruit onto a tubular coring knife that is perforated, thereby cutting an opening through the rind, a pressing head for receiving the said whole fruit which is moved thereinto by the ram which seals in the head, a rind ejector which closes the cylinder so as to oppose the ram, a pressure responsive hydraulic means operating the ram to press the fruit and thereby extrude a core of fruit through said opening cut through the rind and deliver juice from the core, and a core ejector within the coring knife and which is unique in its adaptability to accelerate the rind with the core attached for ejection from the pressing head. The apparatus also includes means responsive to reciprocal motions and timing the functional fruit processing elements.
