2. Description of the Related Art Japanese Unexamined Patent Publication No. 4-145955 discloses a vertical rice milling machine as shown in FIG. The polishing chamber 1 is composed of a polishing roll 2 and a polishing net 3 surrounding the roll. When the drive shaft 4 is rotationally driven, the Hakusei roll 2 and the feed roll 5 are rotationally driven, and the hopper 6 for introducing brown rice is fed.
The brown rice A cut out by the screw 7 is pushed into the polishing chamber 1 by the feed roll 5. The opening of the polishing chamber 1 is regulated by a polished rice outlet forming member 8 and an opening regulating member 9 supported so as to be able to move up and down. The opening degree regulation member 9 adjusts the biasing force of the compression spring 10 according to the lapping accuracy and is pulled upward. When the internal pressure of the polishing chamber 1 becomes higher than the specified pressure due to the pushing by the feed roll 5, the opening regulating member 9 is lowered against the urging force of the compression spring 10 and the opening of the outlet of the polishing chamber 1 is increased, so that the whitening is performed. The internal pressure of the chamber 1 is controlled to a specified value, and the brown rice in the polishing chamber 1 adjusted to the specified internal pressure is stirred by the polishing roll 2 and refined. Rice bran B generated during polishing in polishing room 1
Is discharged from the bran outlet 11a by passing through the polishing net 3 along with the air flow flowing from the polishing chamber 1 through the polishing net 3, and the polished white rice C is regulated with the white rice outlet forming member 8 and the opening degree regulation. It is paid out from between the members 9.

[0003]

In the conventional vertical type rice milling machine 16 as described above, when it is detected that the rotational load of the drive shaft 4 has decreased beyond the specified range, the fed brown rice to the polishing chamber 1 is changed. Judging that it is at the end of milled rice, the urging force of the compression spring 10 is automatically increased to decrease the opening of the outlet of the polishing chamber 1 and increase the internal pressure of the polishing chamber 1 to the maximum tightening position. The degree regulating member 9 is moved and operated in this state for a prescribed time, and then the degree of opening regulating member 9 is lowered to discharge all the rice remaining in the brewing chamber 1 It is possible to process rice even in the final stage of rice polishing when the brown rice fed into the chamber 1 is gone. Also,
Since untreated rice does not remain in the rice polishing machine, even when grains of different varieties are treated one after another, it is possible to obtain the characteristic that grains of different varieties processed last time are not mixed.

In a rice milling facility having a plurality of rice milling machines using a vertical rice milling machine having such a structure as shown in FIG. 6, a single suction is applied to the bran outlet 11b of each rice milling machine 12a, 12b.

In addition, 17 is the bran exit 11a of the rice polishing machine and the rice polishing equipment 12
It is an internal fan provided between the bran outlets 11b of a and 12b.

Specifically, no problem occurs during the operation of each of the rice-polishing facilities 12a and 12b until the final stage of rice-polishing, and the bran B collected from each of the bran outlets 11b through the suction device 13 is Collected in bran tank 14.

However, a problem occurs when any one of the rice-polishing facilities reaches the final stage of rice-polishing. If the rice milling equipment 12a reaches the final stage of rice milling, in the rice milling equipment 12a, as described above, the opening regulating member 9 is moved to the maximum tightening position and continuously operated for a prescribed time, and then the opening regulation is performed. The member 9 is lowered to discharge all the rice remaining in the whitening chamber 1, but the suction force of the suction device 13 acts on the whitening chamber 1 of the rice polishing facility 12a via the milling net 3 of the rice polishing facility 12a. Therefore, even if the opening regulation member 9 of the rice polishing equipment 12a is lowered to discharge all the rice remaining in the polishing chamber 1, the white rice C is sucked and adsorbed by the milled net 3 of the rice polishing equipment 12a to be discharged. Can not do it.
