Cereal separator using size and specific gravity grading
First Claim
1. A cereal separation apparatus comprising:
- a frame;
size grading means mounted at an upper portion of said frame for grading particles according to a size of the particles;
oscillating specific gravity grading means mounted at a lower portion of said frame;
air flow-producing means for producing an air flow for effecting the specific gravity grading; and
a feed passage for feeding the particles, selected by said size grading means, from said size grading means to said specific gravity grading means;
wherein said size grading means comprises a perforated, hollow cylinder for grading the particles according to the particle size, and said cylinder is supported on said frame for rotation about an axis of said cylinder;
wherein said specific gravity grading means is supported on said frame through oscillation support portions;
wherein said apparatus further comprises rotation drive means for rotating said hollow cylinder, and oscillation drive means for oscillating said specific gravity grading means, said rotation means and said oscillation drive means being operable independent of each other; and
an air duct connecting said specific gravity grading means to said hollow cylinder so as to pass the air flow, produced by said air flow-producing means, which has passed through said specific gravity grading means, through said hollow cylinder.

Abstract
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.
