Abstract: A product sorting apparatus is operable to sort products by inducing an oscillating or rocking motion to a plurality of sorting trays in a vertically stacked arrangement. A subset of the products in a top-most tray selectively pass to successive sorting trays. Each of the sorting trays is configured to receive and selectively transmit the selected products according to a separator or sorting panel that is disposed between an input and an output of a given tray. Each of the separator panels defines apertures that facilitate sorting of the products according to size and/or shape. The rocking or oscillating motion has an amplitude and a period according to an input from a drive mechanism, which may include a motor and drive link with a controller and/or a power switch. Optionally, a safety cage and one or more cutoff switches are provided for protecting the sorter and personnel.
