The invention provides environment-friendly intelligent grain flat extruding and impurity removing equipment which comprises a spiral loading machine, a heating cylinder mounting frame, a cereal grainauxiliary heating conveying device, a peeling feeding hopper, a peeling box, a peeling roller, a rotating motor, peeling rubber cushion blocks, supporting frames, a fixing cross rod, a grain vibration separation frame structure, a triangular guiding block, a conveying table and electric rollers. The spiral loading machine is mounted on the lower left portion of the cereal grain auxiliary heatingconveying device. Through arrangement of a ceramic electric heating plate and a heat-insulation shell, the heating effect on cereal grain in a conveying sleeve is advantageously improved, and thus heat is prevented from being outwards diffused; through arrangement of a magnet piece, metal substances in the cereal grain passing through a guiding plate are conveniently sucked advantageously; and through matched arrangement of crushing blades, a connecting shaft and a crushing motor, scraps of the cereal grain are conveniently crushed advantageously, the crushed scraps can serve as animal feed, and then the environment-friendly effect is improved.
