The method for processing the distiller's grains according to claim 3, wherein: no. two magnet (35) keep away from one side of rotating chamber (28) and be equipped with elasticity gasbag (37), elasticity gasbag (37) are used for preventing that No. two magnet (35) from receiving the rigidity collision and the breakage, increase the life of No. two magnet (35), and then further increase the efficiency of grain sediment separation in the lees.
