DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for treating rice bran in a rice mill.

[0002]

2. Description of the Related Art Japanese Patent Laying-Open No. 4-145595 discloses a vertical rice milling machine as shown in FIG. The refining room 1 is composed of a milling roll 2 and a milling net 3 surrounding the outside thereof. When the drive shaft 4 is rotationally driven, the milling roll 2 and the feed roll 5 are rotationally driven, and the hopper 6 for introducing brown rice is used.
The brown rice A cut out from the milling machine 7 is pushed into the milling chamber 1 by the feed roll 5. The opening of the outlet of the refining chamber 1 is regulated by a white rice outlet forming member 8 and an opening regulating member 9 supported so as to be able to move up and down. The opening regulating member 9 is pulled upward by adjusting the urging force of the compression spring 10 in accordance with the grinding accuracy. When the internal pressure of the refining chamber 1 becomes higher than a specified value by being pushed by the feed roll 5, the opening regulating member 9 descends against the urging force of the compression spring 10, and the opening of the outlet of the refining chamber 1 increases, resulting in refining. The internal pressure of the chamber 1 is controlled to a specified value, and the brown rice in the milling chamber 1 adjusted to the specified internal pressure is stirred by the milling roll 2 and milled. Bran B generated by milling in the whitening room 1
Is discharged from the bran outlet 11a through the milling net 3 with the airflow flowing from the milling chamber 1 through the milling net 3, and the milled white rice C is regulated by the milled rice outlet forming member 8 and the opening degree. It is paid out between the members 9.

[0003]

In such a conventional vertical rice milling machine, when it is detected that the rotational load of the drive shaft 4 has decreased and decreased beyond a specified range, the brown rice fed into the whitening chamber 1 is reduced. Judging that the rice mill is at the end of the milling period, the biasing force of the compression spring 10 is automatically increased to reduce the opening of the outlet of the milling chamber 1 and open to the maximum tightening position in the direction of increasing the internal pressure of the milling chamber 1. By moving the degree regulating member 9 and operating it as it is for a specified time, the opening degree regulating member 9 is then lowered to discharge all of the rice remaining inside the polishing chamber 1 so that the polishing is performed. Rice milling can be performed even in the last stage of milling when brown rice sent to the room 1 has been exhausted. Also,
Since unprocessed rice does not remain in the rice milling machine, it is possible to obtain a feature that, even when cereals of different varieties are successively polished, grains of another varieties previously processed are not mixed.

As shown in FIG. 6, in a rice mill having a plurality of rice mills using a vertical rice mill having such a structure, a single suction of the bran outlet 11b of each rice mill 12a, 12b is performed. A configuration in which the bran is recovered by connecting to the bran tank 14 via the device 13 is considered, but in this case, the following problem occurs. 17 is the rice bran outlet 11a and the rice milling equipment 12
This is an internal fan interposed between the bran outlets 11a and 12b.

More specifically, no problem occurs during the operation period until each of the milling equipments 12a and 12b reaches the end of milling, and the bran B collected from the bran outlets 11b through the suction device 13 is removed. Collected in the bran tank 14.

[0006] However, a problem occurs when any of the milling equipment is in the final stage of milling. Assuming that the milling equipment 12a is in the final stage of milling, the milling equipment 12a moves the opening regulating member 9 to the maximum tightening position as described above and continuously operates for a specified time, and thereafter regulates the opening. The member 9 is lowered to discharge all the rice remaining in the milling chamber 1, but the suction force of the suction device 13 acts on the milling chamber 1 of the milling facility 12a via the milling net 3 of the milling facility 12a. Therefore, even if the opening regulating member 9 of the milling equipment 12a is lowered to discharge all the rice remaining in the milling chamber 1, the milling net 3 of the milling equipment 12a sucks and adsorbs the white rice C to discharge the entire quantity. Can not do it.
