Abstract

PROBLEM TO BE SOLVED: To make a large space where bran is stored in a building by forming a projecting part to allow the projection of the upper part of a cyclone in the ceiling portion of the building where the bran generated at the time of a polishing treatment is pneumatically transported and the air and the bran are separated and discharged. SOLUTION: Grains fed into a raw material feeding tank are supplied to an unpolished rice tank 11 of a rice milling apparatus 8 through a lifting machine 7 and is polished in a pearling section 12. The milled rice subjected to polishing is transported to milled rice tank 4 and is recovered. On the other hand, the bran generated in the pearling section 12 is discharged by a blast fan and a suction fan 14 to a bran hopper 13 from which the bran is transported through a bran transporting duct 15 to the cyclone 17. The bran is discharged from a bran discharge port 17b in the cyclone and is fed through a discharge port 20b of a bran transfer trough into a bran bag 9. In such a case, the discharge port 17a for air of the cyclone 17 is disposed taller than the ceiling 18 of the building X, by which the installation place of the cyclone 17 is increased to allow the disposition of the large bran bag 9.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a house-type rice mill.

[0002]

2. Description of the Related Art There is a well-known milling facility in which facilities such as a rice milling machine and a bran processing unit comprising a cyclone and a bran bag are appropriately disposed in a substantially cubic building. In addition, the bran generated in the whitening operation and conveyed by air is centrifuged into air and bran in a cyclone, and the bran falls from the bran discharge port below the cyclone into the bran bag, and the air is discharged into the bran bag above the cyclone. It is also well known that each of the outlets is discharged.

[0003]

In such a rice milling facility, bran can be stored in order to reduce the number of operations of discharging the bran outside the house when the space for storing the bran is full. It is desirable that the space be as large as possible. For that purpose, the installation height of the cyclone above the bran bag needs to be as high as possible. However, since the cyclone has an air outlet above the cyclone as described above, a space must be provided between the cyclone and the ceiling of the building. Therefore, since the installation height of the cyclone in the house is limited, the size of the space for storing the bran is also limited, and the storage amount of the bran cannot be increased.

An object of the present invention is to provide a space for storing a larger amount of bran in a building by efficiently disposing cyclones.

[0005]

The above object of the present invention is achieved by the following constitution. In claim 1, a rice milling machine for whitening the input grains, a conveying means for air-conveying the bran generated during the whitening treatment, and an air outlet and a bran discharging air and bran conveyed by the conveying means. In a rice milling facility in which a cyclone that separates and discharges the outlet and a bran storage unit that stores the bran discharged from the bran discharge port is provided in the building, the upper part of the cyclone is located on the ceiling of the building. A rice polishing facility characterized by forming a convex portion so as to be able to protrude.

According to a second aspect of the present invention, there is provided a rice milling apparatus for whitening the supplied grains, a conveying means for air-conveying bran generated from the rice milling apparatus during the whitening treatment, and a bran storage section for storing the bran conveyed by the conveying means. In a rice milling facility arranged in the building respectively, the rice milling device and the bran storage unit are communicated via a rice bran transport path, and in the middle of the rice bran transport path, the air and rice bran transported by the transport means are transferred. A cyclone that separates and discharges each of the air outlet and the bran outlet is installed,
A rice milling facility characterized in that the cyclone air outlet is located above the ceiling of the building and that the vicinity of the cyclone air outlet is covered with an enclosure.

[0007]

The input grains are supplied to a rice mill and are subjected to a whitening treatment. Then, during the whitening process, the generated bran is transported to the cyclone with air by the transport means,
In the cyclone, air is discharged from the air outlet and bran is discharged from the bran outlet to the bran reservoir in the building. that time,
A convex portion is formed on the ceiling of the building so that the cyclone air outlet can protrude. Accordingly, the installation place of the cyclone can be increased accordingly, so that the space of the bran storage section can be widened, and the number of times of discharging the bran to the outside of the house can be reduced. Also,
A similar effect can be obtained by providing the cyclone air outlet at a position higher than the ceiling of the building and covering the periphery of the cyclone air outlet with a surrounding plate.
