The upper edge 39 of the grinding rice mill 38 is formed as an inclined portion 42 which is cut obliquely, and the outer periphery of the grinding rice mill 38 is surrounded by a bran removing tube 43. A space between the grinding rice polishing roll 38 and the bran removing tube 43 is a grinding rice polishing chamber 44. An inlet 45 is formed at one corner of the lower part of the bran removing tube 43, and a forced supply tube 46 is provided outside the inlet 45. The forced supply cylinder 46 is a vertical cylinder, and a vertical axis 48 is axially mounted on a bottom wall 47, and a downward feed spiral blade 49 is attached to the outer periphery of the vertical axis 48. Lower feed spiral blade 4
Numeral 9 is provided up to near the upper portion of the inflow port 45, and a pushing blade 50 is attached to the area where the inflow port 45 faces. Reference numeral 51 denotes a boss of the pushing blade 50 having a mountain shape. Vertical axis 48
And the upper end of the lower feed spiral blade 49 is a free end.

On the inner surface of the bran removing tube 43, a lower edge 52 is provided.
A spiral 54 reaching the upper edge 53 from the spiral 5 is provided.
Reference numeral 4 denotes a multi-spiral, and nine spirals are provided at equal intervals in the embodiment. The rice bran cylinder 43 and the grinding rice mill roll 3
8 and a lid 55 which can be freely opened and closed
The lid 55 is openable and closable by a hinge mechanism 56 at one end. The lid 55 has a flat circular shape in plan view, and has a circular hole 57 substantially equal to the grain feeding cylinder 33 at the center thereof, and a rotary plate 58 is fitted into the circular hole 57. Approximately six radial guide plates 59 extending from the periphery to the center are attached to the inner surface of the lid 55. The guide plate 59 is radial as a whole, and becomes a bent portion 60 bent in a key shape in the vicinity of the round hole 57 at the inner end, and the grains flowing from the inflow port 45 and rising in the grinding and milling chamber 44 are formed with the guide plate 59. It is supplied to the annular funnel 34 through the communication path 61 between the guide plates 59.

In the middle of the communication path 61, there are provided resistance plates 63 which are pivotally mounted on the longitudinal axis 62 to close the communication path 61, and arms 64 protruding from the resistance plate 63 are provided with projections 65 provided on the rotary plate 58. When the resistance plate 63 feels a load and opens, the arm 64 pushes the protrusion 65 to rotate the rotary plate 58 by the load.

Reference numeral 66 denotes a spring for giving resistance to the rotation, which is connected to the motor 67 and is adjusted in strength. Wherein the lower portion of the friction spinning rice roll 15 to form an annular outlet 68, providing an opening and closing valve 69 for opening and closing vertically moved to the outlet 68. 70 is a support arm, 71 is a spring, and 72 is a motor. A flow control valve 73 is provided above the forced supply cylinder 46. 74 is a motor for opening and closing the flow control valve 73;

[0017]

When the lower passive pulley 14 is rotated by the main motor 76, the friction type milling roll 15 and the lower feed screw spiral 16 are rotated.
When the upper passive pulley 37 is rotated by the auxiliary motor 76, the grinding rice polishing roll 38 is rotated.

In this state, when the longitudinal axis 48 is rotated to rotate the downward feed spiral blade 49, the brown rice in the forced supply cylinder 46 is lowered by the downward feed spiral blade 49 and fed into the inlet 45 by the pushing blade 50. And the grinding and polishing room 44 from the inlet 45
Flows into. The brown rice that has flowed into the grinding rice polishing chamber 44 from the inflow port 45 is such that the subsequent brown rice is forcibly fed by the downward feed spiral blade 49 and the lower edge 5
Since about 9 multi-strip spirals 54 extending from 2 to the upper edge 53 are formed, they are raised in the grinding and polishing rice chamber 44 and are initially polished. The initial milling is performed smoothly because the vertical width of the grinding rice mill roll 38 is small, and the initial milling is performed to raise the guide plate 5.
It is stored in a communication path 61 between 9 and the guide plate 59. 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 produce polished rice. The rice is polished in the room 18.

During the above operation, the bran removing tube 17 wears out in a short time and must be replaced. However, the bran removing tube 17 of the present invention is provided between the upper partition frame 19 and the lower partition frame 20. It is attached and is pressed from the outside by the openable and closable frame 21 after mounting. The openable and closable frame 21 is composed of two sets of right and left, and one end of the left and right free frames 22 and 23 is connected to the longitudinal axis 24.
And the other end of the right and left free frames 22 and 23 are fastened by fixing bolts 26, and the intermediate wall 27 that surrounds the outside of the freely openable and closable frame 21 substantially concentrically is also openable and closable. When the fixing bolt 29 is loosened, the fixing bolt 29 is disassembled to the left and right, and the outer wall 30 of the case 1 where the friction rice polishing
Also, since the lower part can be detached by fitting the lower part and then tightening the upper part with the screw 31, the bran removing tube 17 can be easily replaced when it is replaced.
