The present invention discloses a method for sorting high purity embryo buds of rice. The method for sorting high purity embryo buds of rice comprises a first selection step which selecting rice bran which passes through a vibrating screen with a mesh size of 15-40; a first collection step of collecting rice bran particles by cyclone collection at high temperature; a second selection step of receiving the dried rice bran particles and sorting the rice bran particles by wind based on gravity concentration; a second collection step of blowing and transferring the rice bran particles sorted at the second step by heated air and collecting the rice bran particles by cyclone collection; a third sorting step of sorting the rice bran particles by allowing the dried rice bran particles to pass through a vibrating screen with a mesh size of 30-50; a third collection step of blowing and transferring the rice bran particles sorted at the third sorting step and collecting the rice bran particles by cyclone collection; a fourth sorting step of sorting the dried rice bran particles by colors using a color sorter; a fourth collection step of transferring the sorted rice bran particles by heated air and collecting the sorted rice bran particles by cyclone collection; and removing dust and foreign materials from the dried rice bran particles by high pressure air.
