Abstract
A citrus-juice extractor has two squeeze belts (1, 2) with vertical squeeze surfaces (4) on opposite sides of a progressively narrowed squeeze channel (3). A fruit-half feeder (10) at a wide end of the squeeze channel halves uncut fruit (37) and positions it cut-face-down on a horizontal conveyor (7) intermediate the fruit-half cutter and entrapment positioning between the vertical squeeze surfaces for progressively squeezing conveyance between the vertical squeeze surfaces while the fruit halves are in transit to a narrow exit end (6). Clean-water sprayers (13) and/or other conveyor washers spray-clean the squeeze belts of oil and other contaminants continuously intermediate return belt travel from exit end to the wide end of the squeeze channel. Width of the squeeze channel is pressure-controlled to accommodate widths and consistencies of fruit halves without rupturing the fruit peel.
