As described in Japanese Patent No. 5742, there is a structure in which one building main body is partitioned into three independent rooms: a front operation room, a machine room, and a rice bran storage room.

[Problems to be Solved by the Invention]

However, with such a structure, the building becomes large and the bran accumulated in the rice bran storage chamber has to be collected in a separately prepared bag or the like, which requires time and labor. Of course, it is usually necessary to discharge bran to the outside several times a week, but with the above-mentioned configuration of the prior art, the distance from the bran storage to the open / close door leading to the outside is long. In addition to the transfer work, the transfer work was added, and there was a drawback that the handleability was particularly poor in the machine room.

[Means for Solving the Problems]

The present invention is to solve such a technical problem, and takes the following technical means.

That is, the inside of the grain mill 1 is divided into a machine room 3 and a work room by a partition 2, and the hopper 36 and the grain refiner 38 to which the raw brown rice is supplied are substantially along the partition 2 on the machine room 3 side. , A grain case 5 and a tank 35 of a grain mill having a grain trochanter 21 inside,
A bran collector 9 is provided, and the bran collector 9 is provided closest to a predetermined side wall of the machine chamber 3, and the side wall of the machine chamber 3 is rotated outwardly of the machine chamber 3. The opening and closing door 7 is provided with an opening 8 that can be opened and closed.

[Action / effect]

When the rice bran generated during the grain refinement work is discharged from the grain refinement case 5, the rice bran is collected in the rice bran collector 9 through a guide tube or the like, and is collected in a rice bran bag or the like that stands by below.

During this bran collecting operation, if the opening / closing door 7 is opened, the bran bag below the bran collector 9 is close to the opening 8, so the outside of the grain refiner 1 can be operated manually or by a machine such as a crane. Easy to take out. Of course, since the opening / closing door 7 is rotated outward of the machine room 3 to open the opening 8, the area of the opening 8 can be secured wide and the work of taking out the rice bran bag can be performed very easily. .

In addition, since the hopper 36, the grain raiser 38, the grain refiner, and the bran collector 9 are installed side by side in the machine room 3 substantially right and left, the work such as the inspection of the machine part can be simplified and the partition wall can be provided. An inspection / cleaning passage is formed between the machine 2 and the rear wall of the machine room, but this can be set small and the interior of the grain mill 1 can be made compact.
