Then, the grains on the rocking sorting plate 17 quickly flow to the rocking side 17c, the amount of grains partitioned by the brown rice partition plate 26 increases, and the mixed rice in the mixed rice uneven distribution distribution basin in the middle portion decreases, Many grains separated by the brown rice partition plate 26 flow into the brown rice fried machine 7 and are fried because the brown rice switching valve 34 of the brown rice flow passage 31 is automatically or manually switched to the brown rice flow passage 31 side. Grains are extracted from the residual grain extracting unit 60 through the residual grain switching valve 59 of the brown rice extracting unit 32. In this way, when the residual grain is taken out, the swing rotation speed of the swing sorting plate 17 becomes high-speed, the grain is swung to the upside 17c a lot, and the grain amount partitioned by the brown rice partition plate 26 increases, Can reduce the grain in the mixed rice distribution basin,
