This embodiment is constructed as described above, and when paddy is put into the hopper (2), the paddy is removed by the removing rolls (3) and (4) and the grain board (9) is removed. )
The brown rice and the paddy that fall through the tray drop onto the second gutter (10), are taken out by the mixed rice conveyor (11), and are lifted to the mixed rice hopper (22) by the mixed rice thrower (16). At this time, the rice porridge that is selectively air-dropped on the third gutter (12) is discharged to the outside of the machine by the rice porcelain conveyor (13), and the rice husk is sucked together with dust by the suction / exhaust dust fan (14). The mixed rice (brown rice and paddy) carried into the hopper (22) is fed to the mixed rice supply conveyor (24) to the upper sorting cylinder (18).
As shown in FIG. 4, the mixed rice is agitated so as to come into contact with the inner peripheral surface of the upper sorting cylinder (18) which continuously rotates in one direction, as shown in FIG. Recessed hole (1
8a) is lifted up and dropped onto the upper surfaces of the upper brown rice receiving gutters (25).
5) The inner brown rice is carried into one end of the lower sorting cylinder (19) by the upper brown rice removing conveyor (26) through the feed gutter (27), while the recessed hole in the inner peripheral surface of the upper sorting cylinder (18). The paddy that does not fit into (18a) slides down and moves to the other end of the sorting cylinder (18), so that the paddy is returned to the hopper (2) through the paddy-returning gutter (28) for re-hulling. In addition, since some paddy is mixed in the brown rice carried into the lower sorting cylinder (19) through the feeding gutter (27), the upper sorting cylinder (1
Similar to 8), the lower selection tube (19) further separates brown rice and paddy, and the brown rice falling into the lower brown rice receiving gutter (29) is fed to the lower brown rice removing conveyor (30) to the brown rice gutter (3).
Take out to 1) and carry out the brown rice falling from the brown rice gutter (31) to the first gutter (6) by the brown rice slower (15) to the outside of the machine, and the paddy inside the lower sorting cylinder (19) contains some brown rice. The mixed rice gutter (3
Since it falls through the 2) to the second gutter (10), the unhulled rice containing brown rice is reduced to the mixed rice hopper (22) and re-sorted.

During such work, when the supply of the mixed rice in the hopper (22) becomes insufficient and the dep rolls (3) and (4) are in an idle state, the sensor (59) detects this and gives an instruction. The display value of the total (61) is set to zero and the generation of sound from the speaker (62) is stopped to notify the operator of this.

On the other hand, when it is necessary to set the roll gap (c) to the reference gap, the rolls (3) and (4)
When the roll (3) and the roll (4) come into contact with each other to make a contact sound by gradually narrowing the gap (c) from a position slightly separated in advance, the indicator (6) is passed through the sensor (59).
The operator senses the zero state of the roll gap (c) by means of 1) and the speaker (62). In this state, the zero adjustment of the handle (56) is performed, and then the scale of the handle (56) is adjusted. The gap between the rolls (3) and (4) is opened to a predetermined roll gap (c) by operation.

As described above, as compared with the conventional means for zeroing the roll gap (c) by directly listening to the contact sound of the rolls (3) and (4) by the operator's ears, the means for the means is the above-mentioned instruction. Since it is performed by the meter display of the total number (61), the roll gap (c) can be accurately zeroed without any individual difference, and as a result, the roll can be rolled in the standard gap so that the proper removal rate can be obtained. When the gap (c) is set, accurate setting can be performed, and therefore an efficient removal process can be performed.
