  • Publication number: 20090188842
    Abstract: A method and apparatus are provided for separating elastomeric materials from mixed material streams. A separator includes a bank of parallel rollers extending longitudinally between a first end and a second end. The bank of parallel rollers having a predefined inclination with the first end elevated higher than the second end. Mixed material streams are fed onto a top surface of the high end of the inclined parallel rollers. A material having less friction and elasticity slides down the inclined roller bank top surface are collected into a collection bin positioned adjacent the second, lower end of the roller bank. Other materials having a higher friction coefficient grip the rollers more and are lifted out of the valley due to friction migrating perpendicular to the rotating rollers and are collected in a collection bin positioned adjacent one side of the roller bank parallel to the longitudinal roller axis.

    Abstract: The present invention provides a unique mechanical method and device for sorting pieces (e.g. vegetables and fruits) of any desired size from unsorted and irregularly sized pieces. The device includes a pair of elongated cylindrical brushes, one of which is equipped with a spiraled furrow for propelling the unsorted pieces and another brush being a smooth surfaced bristled brush (an expelling brush) laterally positioned to the propelling brush so as to form a trough between the two brushes for longitudinally moving the pieces. The brushes are rotated in a common rotational direction. A contacting member, such as a pivotally mounted lever, traversing the trough and the smooth surfaced brush and laterally positioned above the trough at a predetermined distance will tangentially contact a piece of a desired sizing and guide the contacted piece along its interfacing surface.

Mushy cranberries do not clog the separator.Pressure is repeatedly applied to each cranberry, to a pressure less than 0.50 psi, as cranberries are transported from a loading hopper, along a roller conveyor, to an outlet.The roller conveyor comprises an overhead soft roller, and a finned hard roller, mounted under the soft roller. Each cranberry passes between multiple pinch points, between the upper and lower rollers.Each cranberry is supported across two fins, at the pinch point. Soft cranberries are forced between the fins, and are stripped out from between the fins, by comb teeth, extending upwardly between the fins. After each pinch point, the cranberry is rotated randomly, to present a new surface to be tested.
