GRAIN TREATMENT APPARATUS

PROBLEM TO BE SOLVED: To obtain a rice milling machine which can prevent the leakage of the brain in a bran chamber during milling. SOLUTION: A separation basket 31 having an open upper surface having numbers of separation holes is placed in a container 21 having a rotary shaft 27 rotated by a driving mechanism 10 in an apparatus main body 1 to be able to go in and out. An agitation tool 41 is fitted to the shaft 27 and rotated in the basket 31, with rice in the basket 31 being agitated, bran is separated into a bran chamber C between the container 21 and the basket 31 through the separation holes of the basket 31 for milling. The basket 31 has a ring- shaped protruding flange 32c which hooks the bran chamber C from above to the upper end opening fringe 21a of the container 21 to close the upper end opening of the bran chamber C and is positioned close to the lower side of the flange to attach a ring-shaped rubber seal packing 48 to the periphery of the basket 31. The packing 48 has a lip part 48b being in elastic contact with the inside surface of the container 21, and the upper end opening of the container 21 is sealed by the lip part 48b.
