  • Patent number: 5271506
    Abstract: An improved apparatus for sorting agricultural products such as vegetables or fruits from dirt clods, rocks, or other debris, without bruising the desired product. The mixture of desired product and undesired debris is transported by conveyor and allowed to fall freely on a rotating roller. The individual components rebound differentially from the roller, separating the product and the debris. The roller is constructed of a loose-fitting sleeve supported and rotated by resilient disks on a rotating shaft, with the resilience of the disks minimizing the bruising of the product rebounding from the roller.
