Abstract
A grain processing apparatus is used in one embodiment for debranning grain to remove the bran. In another embodiment, it is used as a mill for milling flour. The processor includes a cylindrical drum with an internal rotor having a set of impeller rods. The grain is loaded into the drum and is withdrawn as debranned kernels or flour as treatment proceeds. Bran removed from the grain is withdrawn through a vacuum discharge at the top of the apparatus. The grain is either discharged through a grain discharge or, where it is to be milled, it is withdrawn through the vacuum discharge as flour. The relatively coarse bran can be separated from the flour using a sifter. The air flow withdrawing the flour from the drum is drawn into the drum at the bottom, through a venturi and a valving arrangement. This cools the inlet air and maintains the temperature of the drum at an acceptable temperature.
