Abstract: Good legumes or pistachio nuts are separated from those to be discarded by feeding the pistachios or legumes to a longitudinally inclined trough between a laterally inclined plate and a rotating cylinder, such cylinder having outwardly projecting edges along its exterior surface. On the opposite side of such cylinder is provided a second cylinder having a brush on its outer circumference, and the two cylinders are driven in opposite directions. Good legumes and pistachio nuts are merely tumbled within the trough by the first cylinder and are fed partly by gravity to a collector at the foot of the device. The unsatisfactory legumes and pistachios are picked up by the outwardly projecting edges of the first cylinder and flipped over where they are then brushed downwaardly off the first cylinder by the brush of the second cylinder.
