PROBLEM TO BE SOLVED: To prevent long size material such as straw from being incorporated into a rice milling device by making a grain discharge port of a pebble removing device and a grain feeding port of a foreign matter removing device communicate with each other so that fall feeding is performed and making a grain discharge port of the foreign matter removing device and a grain feeding port of a grain lifting device with each other so that fall feeding is performed. SOLUTION: After grains fed into a rice milling facility is fed to a pebble removing device 7 to select by specific gravity pebbles in the grains by an oscillating and sorting plate 7a of the pebble removing device 7, from a grain discharge port 7a of the pebble removing device 7, the grains are fed by fall to a grain feeding hopper 46 of a foreign matter removing device 8. After the grains and the long size material such as straw fed to the foreign matter removing device 8 are separated and sorted while receiving conveying action, the grains are fed by fall to a grain feeding port of a grain lifting device from a grain discharge cylinder 44 of the foreign matter removing device 8. Further, the grains fed to the grain feeding port of the grain lifting device are lifted and receive polishing action in a rice milling device. In this way, by providing the foreign matter removing device 8, long size material such as straw can be prevented from being incorporated into the milling device.
