  • Patent number: 6780451
    Abstract: A method for separating juice vesicles from a citrus fruit includes the step of forming a plurality of generally circumferential scores between a stem end and a stylar end of a citrus fruit. Preferably each score extends at least through a flavedo of a peel of the fruit. Next the fruit is cut into a plurality of slices in a direction normal to a longitudinal axis defined by the stem end and the stylar end. The slices are then frozen, and an impulsive force is applied to the slices to form a plurality of fruit components. These fruit components comprise juice vesicles and other fruit components, such as the peel, connective membranes, and seeds. The juice vesicles are then mechanically separated from the other fruit components.

  • Patent number: 6718868
    Abstract: A peeling device supports a fresh commodity in a first position in a nonspecific orientation. The commodity is impelled using a thruster toward a scoring structure for scoring the peel to a predetermined depth into two sectors. Peel grippers hold the peel between the scores and release the peeled commodity, such that the peel is retained on the gripping means. The thruster is positioned and adapted to force the commodity along a path to engage the cutting and peel-gripping elements, the thruster bottom surface changeable from a first, generally concave orientation for conforming to a shape of the commodity to a second, generally convex orientation for releasing the commodity from the peel.

  • Patent number: 6371014
    Abstract: The system for peeling a fresh commodity includes barbs for piercing the peel in a plurality of spaced-apart locations. A vacuum infuser is used to infuse the pierced commodity with an aqueous solution to loosen the peel. A peeling device supports a fresh commodity in a first position. The commodity is impelled toward a structure having cutting elements for scoring the peel to a predetermined depth. Preferably the scores are made along generally circumferential lines having substantially common endpoints. Peel grippers hold the peel between the scores and release the peeled commodity, such that the peel is retained on the gripping means. A thruster is positioned and adapted to force the commodity along a path to engage the cutting and peel-gripping elements.

  • Patent number: 5817360
    Abstract: A method of pretreating citrus fruit for facilitating peeling utilizes infusion with an aqueous solution for loosening the peel from the underlying segments. In a first embodiment an infusion of water having essentially neither enzyme nor any other additive therein is accomplished with the use of a pressure or a vacuum apparatus. Further embodiments include making a pair of opposed holes in the peel and forcing an aqueous solution that may or may not contain an enzyme or an additive at low pressure into one of the holes until it emerges from the other hole. In one embodiment water pressure from a faucet may be used; in another, a flexible injection nozzle is used as an interface between the solution source and the inlet hole. All embodiments serve to separate the peel from the segments by hydrating the albedo, making the fruit easier to peel.

  • Patent number: 5560951
    Abstract: A method of pretreating citrus fruit for facilitating peeling utilizes water infusion without enzymes for loosening the peel from the underlying segments. The infusion may be accomplished with the use of a pressure or a vacuum apparatus. A further embodiments, which may be used in the home, consists of cutting a pair of opposed holes in the peel and forcing water into one of the holes until it emerges from the other hole. Both embodiments serve to separate the peel from the segments, making the fruit easier to peel.
