FIELD: grain processing equipment. SUBSTANCE: shelling machine has ribbed cylindrical housing, bladed rotor mounted within housing, feeding auger, discharge device and grain baffle. Feeding auger is surrounded with cylinder having grain inlet and outlet windows to provide for uniform grain feeding and discharge. Grain inlet window is larger than grain outlet window. Auxiliary blades are mounted in inclined position on main blades. Main blades are provided with longitudinal slots creating pulsed compression zones in annular grain layer. Longitudinal slots are inclined relative to blade working surfaces toward rotor axis in direction reverse to direction of rotation of these blades. Blade surfaces are made corrugated to intensify shelling process. EFFECT: simplified construction, increased efficiency and enhanced reliability in operation. 2 cl, 8 dwg
