An annular outlet 68 is formed in the lower portion of the friction-type grain roll 15, and an opening / closing valve 69 that moves up and down to open and close is provided at the outlet 68. Reference numeral 70 is a support arm, 71 is a spring, and 72 is a motor. A flow rate control valve 73 is provided above the forced supply cylinder 46. 74 is a motor for opening and closing the flow control valve 73,
75 is a remaining rice blowing port, 76 is a main motor, 77 is a sub motor,
79 is a grain feeding room, 86 is a blower blower, and 89 is a forced supply cylinder 4.
It is a mounting frame for mounting 6.

The grain feeding cylinder 33 and the mounting frame 89 are provided with a screw 78.
When removed, all are removed together from the case 1, and the downward feed grain spiral 16 is exposed. FIG. 3 shows the exposed lower feed grain spiral 16 surrounded by a hopper 88. By doing so, a simple vertical rice milling machine is used.
3 and the one shown in FIG. 3 are combined to form a continuous rice milling machine, so the parts above case 1 may be manufactured separately and transformed by order.

In the structure shown in FIG. 2, when the lower passive pulley 14 is rotated by the main motor 76, the friction-type grain rolling roll 15 and the lower feed grain spiral 16 are rotated, and when the auxiliary motor 76 is rotated by the upper passive pulley 37. The grinding grain roll 38 rotates. In this state, when the vertical axis 48 is rotated to rotate the lower feed spiral blade 49, the brown rice in the forced supply cylinder 46 is lowered by the lower feed spiral blade 49 and is fed into the inflow port 45 by the pushing blade 50, so that Ascending-type grinding grain chamber 44 from entrance 45
Flows in. The brown rice that has flowed into the ascending-type grinding grain chamber 44 through the inflow port 45 is that the subsequent brown rice is forcibly fed by the downward feed spiral blades 49, and that the inner surface of the bran removing cylinder 43 is located above the lower edge 52. Since about nine multi-threaded spirals 54 reaching the edge 53 are formed, the inside of the lifting-type grinding and graining chamber 44 is easily lifted, and 10% or 20% of the initial polishing is performed, and then the rising guide plate 59 is formed. It is stored in the communication path 61 between the guide plates 59.
Grains stored in the communication path 61 gradually increase in pressure and press the resistance plate 63 to open, gradually flow into the grain feeding cylinder 33, and are fed downward by the downward feeding grain feeding spiral 16.
Finished rice is milled in the flow-down type friction grain chamber 18.

In FIG. 3, the screw 78 is removed and replaced, and when brown rice is supplied to the hopper 88, the brown rice flows into the grain feeding cylinder 33 and is fed downward by the downward feeding grain feeding spiral 16. The rice is milled in the flow-down type friction milling room 18. In the combination of FIG. 2 and FIG. 3, the rice milled in the downflow-type friction milling chamber 18 of FIG. 2 enters the hopper 88 of FIG. It is something.
