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. The rotational brushing movement of the smooth bristled expelling brush moves the contacted pieces along the contacting surface to a position where it may be expelled onto a collecting station.
