METHOD OF GRAIN STEAMING ACCORDING Russian patent published in 1994 - IPC

FIELD: agricultural engineering. SUBSTANCE: method includes grain charging into the working chamber with a vertical auger whose blades have a decreasing diameter in the auger lower part, the grain processing in the working chamber with steam and the unloading of the steamed grain. Longitudinal notches having the cross-section of the trapezoidal shape with protrusions of the convex shape between them are made from inside in the housing segment surrounding the auger part having a small diameter. The sum of the notch depth and the protrusion height is less than the sizes of the weevil. EFFECT: facilitated manufacture. 3 dwg
