  To explain the operation in the above configuration, polished rice for the purpose of washing rice is introduced into the rice storage unit 2. By operating an operation switch (not shown), the rice weighed by the weighing unit 3 is put into the rice polishing apparatus 4. Then, the main shaft 15 is rotated by the polishing rice motor 14, and the polishing drum 16 fitted to the main shaft 15 is rotated. The rice at the bottom of the rice polishing apparatus 4 is given centrifugal force by the rotation of the rice polishing drum 16 and presses the rice grains against the side surface of the rice polishing drum 16, so that the rice grains rise in order and fall at the top. The rice circulates in the research apparatus 4.

  On the other hand, the circulation described above promotes the friction between the rice grains by centrifugal force while the clearance S between the side wall of the separating portion 17 and the outer peripheral portion of the brush bristles 16a is increased, and the tip of the bristles 16a is the surface of the rice. Enter the ditch and scrape the rice cake or rice surface powder. The separated soot and the like are discharged into the soot collection space 20 of the soot collecting unit 7a through the hole of the separating unit 17.

  During rice polishing, the rice discharge valve 18 that had closed the lower opening 17b of the separating portion 17 dropped downward, opened the lower opening 17b, and discharged the rice inside the rice receiver 10 through the rice guide 19. To do.

  Next, the state of soot collection in the soot collection unit 7a and the cyclone unit 7b will be described. When the suction motor 6 operates, the suction fan 5 rotates, and an air flow that flows from the air intake port 20b to the intake port 5a through the soot collection space 20 is generated. The air is cooled from the exhaust portion 5b to the polished rice motor 14, and then discharged from the exhaust port 1a opened outside the rice sharpener body 1. When air mixed with soot flows from the soot discharge port 4a through the inflow port 7ba of the cyclone portion 7b, it becomes a swirling flow at the swiveling portion 7c of the cyclone portion 7b, and the soot is pressed against the wall surface by centrifugal force. , Deposited on the soot receptacle 22.

  A part of the fine soot flows into the filter 25 from the vent 24b together with the air without being separated from the air. In the filter 25, the remaining soot is separated, and only the air from which soot has been removed flows to the intake port 5a. The wrinkles adhering to the filter 25 can rotate the filter cover 26 at the top of the filter 25, so that the ribs 26 a come into contact with the protrusions 25 a of the filter 25, and can vibrate the filter 25.
