A cereal separation apparatus includes a frame and a size grading device mounted at an upper portion of the frame for grading particles according to a size of the particles. An oscillating specific gravity grading device is mounted at a lower portion of the frame. An air flow-producing device produces an air flow for effecting the specific gravity grading. A feed passage feeds the particles, selected by the size grading device, from the size grading device to the specific gravity grading device. The size grading device comprises a perforated, hollow cylinder for grading the particles according to particle size. The cylinder is supported on the frame for rotation about an axis of the cylinder. The specific gravity grading device is supported on the frame through oscillation support portions. The apparatus further comprises a rotation drive device for rotating the hollow cylinder and an oscillation drive device for oscillating the specific gravity grading device. The rotation means and the oscillation drive means are operable independent of each other. An air passage connects the specific gravity grading means to the hollow cylinder so as to pass the air flow, produced by the air flow-producing means, which has passed through the specific gravity grading means, through the hollow cylinder.
