The present invention relates to a grain cleaner for cleaning cereals such as sesame, perilla, and rice, and more particularly to a grain cleaner for cleaning grain such as sesame, perilla, rice and the like, The filtration body of the filtration body for filtering out foreign matter such as sand or soil is formed into an arcuate shape whose upper portion is opened and whose lower portion is inclined. The lower depth of the arc portion adjacent to the inner wall surface of the grain washing cylinder is low Wherein a lower depth of a chord portion adjacent to the impeller is formed deeply and an inclined surface is inclined inwardly on an upper surface of the arc portion and a chord portion is formed to protrude toward the arc portion side, By providing the filter net on the inclined bottom surface of the filtration body, foreign matter such as sand contained in the water stream rotating together with the washing water from the upper side of the filtration body is easily introduced into the inner space of the filtration body, Foreign matter from entering the inner space of the body part is to avoid injury to the upper side by a locking jaw of the upper to the lower side while Rana inclined. The present invention is characterized in that a grain cleaning flask 2 is provided on the upper side of the cleaner main body 1 and a drain port 3 is formed at a predetermined position on one side of the bottom surface of the grain cleaning flask 2, And a rotary impeller 6 having upper and lower impeller blades 5 protruded at an eccentric position of the bottom surface is rotatably supported by a motor 7, And a grain outlet 9 connected to a grain outlet pipe 10 is formed outwardly at a predetermined position of the bottom surface and a grain outlet 9 is opened and closed at a predetermined position of the grain cleaning vessel 2 The present invention relates to a grain washing machine in which a door opening and closing port 12 is provided by an opening and closing lever 13 and a
