When the upper passive pulley 37 is rotated by the auxiliary motor 76, the grinding type milling roll 38 rotates. When the lower feed spiral blade 49 is rotated by rotating the vertical axis 48 in this state, the brown rice in the forced supply cylinder 46 is lowered by the lower feed spiral blade 49 and is sent into the inflow pipe 45 by the pushing blade 50 to be inflowed. It flows into the ascending grinding and graining chamber 44 from the pipe 45. The brown rice that has flowed into the ascending grinding and milling chamber 44 from the inflow pipe 45 has the following brown rice being forcibly fed by the downward feed spiral blades 49 and the inner surface of the bran removing cylinder 43 from the lower edge 52 upward. Approximately 9 multi-spiral spirals 54 leading to the edge 53 are formed, and the vertical width of the grinding type milling roll 38 is 0.3 to 0.5 when the diameter is 1 and the vertical width is small. From (the dimensions in the example diagram are roughly the scale ratios of the dimensions of the actual product), the ascent or grinding in the ascending grinding and milling chamber 44 is performed without difficulty, and the initial milling of 10 to 20% is performed. Guide plate 5
9 are stored in the communication path 61. The grain stored in the communication path 61 gradually increases the pressure and pushes the resistance plate 63 to open it. The grain gradually flows into the grain feeding cylinder 33 and is sent downward by the downward feeding grain spiral 16 to flow downward. The rice is milled in the grinding and milling room 18.
