Description

[Detailed description of the invention] The present invention relates to an improvement of a grain sorting device for a grain milling machine.

Conventional grain milling machines for sake brewing that mill rice to a milling rate of about 70 to 75% connect a sorting device consisting of a rice bran removal sieve to the discharge port of the milling chamber to remove the bran powder generated during the milling process. The configuration is customary. By the way, when continuing to remove bran during milling of sake-brewing rice that generates a large amount of bran powder, when the milling rate reaches around 72%, squeaks occur between the particles in the milling chamber, so an appropriate amount of bran powder is added as a buffer material. need to be held.

In addition, the rice milling rate is 90-92% using compass rice milling equipment, etc.
When the milled rice is fed to the grain mill for sake brewing to continue the milling process, the vibrating sieve is operated to remove the bran, which acts as a buffer for the rice grains inside the milling chamber. As the amount of bran powder gradually becomes insufficient and the load in the milling room acts directly on the polished rice, the surface of the polished rice grains is damaged and absorbs a large amount of water during soaking, causing ice shavings, and the grains are broken frequently, reducing yield. It had defects that led to a decline in quality.

The present invention is intended to solve the above-mentioned drawbacks, and it is possible to easily and reliably switch between the milling of brown rice, which produces a large amount of bran, and the milling of general white rice, which has a small amount of bran. However, it is an object of the present invention to develop and provide a high-performance grain sorting device that smoothly performs a high-efficiency milling operation.

Embodiment diagrams of the present invention will be explained. In FIG. 1, the symbol 1 indicates #! which has a grain sorting device 2 connected to its lower part! This is a grain milling device in which a grain tank 3 is mounted on the upper part of a grain master machine and the M master machine 1, and an elevator 4 is erected on the negative side thereof to integrally form a grain circulation process. The grain milling machine 1 (see FIG. 2) has a vertical shaft 7 rotatably attached to the center of a base plate 6 provided inside a grain milling mantle 5, and a grinding roller 8 on the base plate 6. At the same time, the lid part 9 placed on the trochanter 8 is fixed and integrally fixed to the vertical shaft 7, and the grain tank 3 in the upper part is connected to the milling room 1.
The rice grains flowing down into the rice mill are milled by a rotating grinding rotor 8, and the polished rice is discharged through a discharge port 11 provided in the grain milling mantle 5 and flows down to the grain sorting device 2 at the lower part.

Next, in the grain sorting device 2, in the vibration 11i14 for bran removal constituted by the vibration device 12 and the porous wall plate 13 for rice bran removal, a non-perforated plate for flowing grain is attached to the upper part of the porous wall plate 13 for rice bran removal. 1
5 is installed to integrally form a sieve body 16, and the whitening chamber 1
A supply hopper 17 that communicates with the discharge port 11 of the sieve body 16 is provided in the supply section of the sieve body 16, and a side wall 18 is erected inside the supply hopper 17 to provide a first channel 1 that communicates with the non-perforated plate 15.
9 and a second flow path 20 communicating with the porous wall plate 13, a flow path switching valve 21 is rotatably provided at the upper end of the side wall 18, and 22 is an operating rod of the switching valve.

With the above configuration, when brewing rice is milled from brown rice, the operating rod 22 is rotated to close the first channel 19 and open the second channel 20, and at the same time, start the device. Then,
The brown rice supplied to the grain tank 3 is sent to the milling room 1 of the grain milling machine 1.
In the milling chamber 10 , the milled rice is milled by the rotating grinding rotor 8 and discharged from the discharge port 11 .
The adhering bran powder is removed while flowing down the porous wall plate 13 for bran removal in i14, and the polished rice from which the bran has been removed flows into the grain tank 3 via the elevator 4. When this grain circulation process is repeated several times and the milling rate reaches around 80%, the amount of bran in the milling chamber 10 becomes insufficient and a creaking phenomenon occurs. The flow path 20 is closed and the first
The flow path 19 is opened. Therefore, the subsequent polished rice is passed through the first channel 19 of the supply hopper 17 to the non-perforated grain plate 15.
Since the rice is circulated through the rice milling device with the rice bran attached to it, the amount of rice bran in the polishing chamber 10 is maintained at an appropriate level, and the polished rice is smoothly milled without causing the above-mentioned squeak phenomenon. When the rice milling rate reaches , the rice is taken out of the machine via the elevator 4. In addition, when milling general white rice with a milling rate of about 90 to 92%, the operating rod 22 is rotated to open the first channel 19 and close the second channel 20, and at the same time, start the device. Then, the polished rice discharged from the outlet 11 of the milling room 10 flows down the non-perforated grain plate 15 through the first channel 19 in the supply hopper 17 and circulates through the grain milling device, so that the rice bran is removed. The adhered polished rice flows into the whitening chamber 1o, and the amount of bran powder in the whitening chamber is maintained at an appropriate level. When the rice milling rate reaches around 85%, the rice bran becomes excessive, so the operating rod 22 is rotated to close the second flow path 20 and the rice bran is passed through the porous wall plate 13 for removing the rice bran. and perform the purification process.

5- Therefore, high-quality sake-brewing rice can be milled reliably and smoothly without causing the aforementioned damage to the rice grains.

In this way, the grain sorting device of the grain milling machine of the present invention can easily switch between the milling action for brown rice, which generates a large amount of bran powder, and the milling action for ordinary white rice, which produces less bran powder, in the milling of sake-brewing rice. This method can be carried out easily and reliably, and has the effect of smoothly carrying out a high-efficiency milling operation to ensure high-quality sake-brewing rice.
