The invention discloses a high-efficiency black rice husking device. The high-efficiency black rice husking device comprises a granary and a storage bin. A first husking machine and a second husking machine are fixedly mounted on the left side of a first elevator in sequence. The left side of the bottom of the second husking machine is fixedly provided with a second elevator. The left side of thesecond elevator is fixedly provided with a separation tank. The left side of the separation tank is fixedly connected with a discharge pipe. The left side of the separation tank is fixedly provided with a third elevator. The front side of the storage bin is fixedly provided with a hopper. A third grain guide pipe is fixedly connected between the top of the hopper and the top of the third elevator.The bottom of the hopper is fixedly connected with a discharge pipe. The right side of the storage bin is fixedly provided with a negative-pressure adsorption fan. A first delivery pipe is fixedly connected between the negative-pressure adsorption fan and the first husking machine, a second delivery pipe is fixedly connected between the negative-pressure adsorption fan and the second husking machine, and a third delivery pipe is arranged between the negative-pressure adsorption fan and the separation tank. The high-efficiency black rice husking device improves the husking efficiency and fullyseparates out rice skin blended in black rice grains after husking.
