ABSTRACT:
Fruit juice extraction apparatus in which a pair of confronting frusto-conical discs are supported on a rotatable main shaft by ball and socket connections and retained in angular tilted relation by guide bearing assemblies to provide a point of minimum peripheral spacing between the discs on one side, a stationary wall being interposed between the discs and cooperating therewith to form separate pressure-applying travel paths for the respective halves of cut fruit sections, each of the paths converging in the direction of disc rotation from a path inlet adjacent the minimum spacing point to an outlet. The whole uncut fruits are supplied in advance of the minimum spacing point and gripped between the discs and carried to a slicing knife for cutting into half-sections which are carried through the converging paths and forced against perforate portions of the stationary wall by progressively applied pressure to extract the juice. As the outlets of the paths are approached, the cut faces of the fruit sections are forced against stationary spaced bars between which the pulp projects. A pair of rotatable rolls supported between the discs at the outlet have surface projections which extend between the bars to engage, further squeeze and remove the pulp projecting between the bars, and at the same time move the fruit section against a knife to shear the pulp from the peel. Length adjustable collar spacers on the main shaft provide relative spacing adjustments of the discs and stationary wall.
