A device is described which effects a continuous separation of internally infested wheat from sound wheat, and which separates wheat into a number of fractions of different test weight. A stream of wheat, projected into still air by rapidly moving belts, is dispersed by the combined effects of air drag and gravitation into numerous fractions which are caught in a series of hoppers. Infested kernels fall short of sound grain and are thus separated. Test weight varies progressively and characteristically with distance from the point of projection.
