  • Patent number: 4729299
    Abstract: This invention relates to a method and apparatus of peeling citrus fruit. Citrus fruits are peeled by utilizing a series of cups for holding the fruit such that the core axis of the fruit lies horizontal at right angle to the path of travel. A conveyor is used for advancing the cups in a series of stop/start motions along the path of travel while the fruit is being held in the cups by means of a series of metallic fingers applying downward pressure on the fruit. The blossom and stem of the fruit are sliced to establish parallel planes on the fruit such that the fruit can be guided along parallel plates to prevent movement of the core axis of the fruit. A pair of photo-electric cells will estimate the diameter of the fruit and the information stored for further processing. The fruits are then pierced by means of forks or tines which will rotate them at a constant speed and be carried below a set of rotating cutters.
