ABSTRACT:
An automatic juice extraction machine for squeezing juice from one or more pieces of fruit in accordance with this invention comprises at least one pair of cups disposed in a vertically aligned relationship, with the lower of each related pair of cups utilizing a series of spaced, upwardly extending fingers and a centrally disposed fruit piercing tube. This tube defines part of a passageway located directly below each lower cup, in which passageway a strainer is disposed. Each upper cup, defined by spaced, downwardly extending fingers, is mounted on a vertically movable member movable between spaced vertical positions. The spacing of the fingers allows the fingers of the upper and lower cups to mesh, to bring about squeezing of the fruit. We utilize a pneumatic device for causing a single piece of fruit to be inserted into each lower cup subsequent to the raising of the vertically movable member. Located above the strainer is a rotary valve and below the strainer is a pulp squeezing device, latter being vertically operable in the lower passageway end. The valve is movable to a passage-closed position substantially contemporaneous with the pulp squeezing device moving upward in the passageway, to compress the pulp therein. An orifice of selected size is utilized to provide a degree of inhibition to seeds and peel portions exiting downward through the passageway, thus to determine the amount of pressure existing in the pulp during the ascent of the pulp squeezing device.
