るという問題点があった。(Prior art) Conventionally, a rotary shaft is passed through a bran removal wire mesh in which a large number of slits are formed, and a polished trochanter equipped with stirring protrusions or made of diamond sand is attached to the rotary shaft, and In rice mills equipped with screw rolls that feed a constant amount of rice grains fed from the feed port to the milling trochanter, the rice grains that are attached to the screw rolls are unevenly pounded, and even polished. In other words, the rice grains transported from the supply port by the screw roll had a slight amount of the bran layer on the surface peeled off due to grain r* rubbing, and at this time, the rice grains were slightly peeled off due to FM rubbing. The heat generated causes the oil and fat components in the noodle vat to melt and wet the peaks and troughs of the screw roll, so the rice bran adheres to the surface of the screw roll and gradually becomes a thick sticky bran, which reduces the conveyance capacity of the screw roll. As a result, the amount of grain fed to the milling trochanter decreases, and the internal pressure does not rise, resulting in poor milling.To avoid this, increasing the pressing force of the resistance lid as a variable resistance will reduce the amount of broken rice. There was a problem that occurred.

着糠を防止しようとするものである。Therefore, the dewaxing rice polishing method shown in FIG. 6 was proposed to solve this problem. Japanese Patent Publication No. 56-38138j
This invention disclosed as Publication No. 5 has the advantage that the bran continuously discharged from the bran removing net 101 is removed by approximately 9
0% is the cyclone separator 104 through the large vibrator 103
Then, the remaining 10% is transferred to the hopper 10 through the small pipe 105.
The brown rice is sent to the separator 107 in the hopper 106, and the brown rice is flown down from the lower end of the separator 107 together with the brown rice in the hopper 106.
The brown rice is sent to the polishing roll 109 side while being stirred at step 8, thereby absorbing the liquefied wax on the surface of the brown rice and preventing rice bran from sticking to the rice feeding helix 108.

Wind to separator 107 in 6? Technically difficult to adjust,
If the amount of 8a is not optimal, there is a risk that the bran that should fall downward will be scattered with the air, not only making the addition of bran unstable but also contaminating the working environment. Met.

リングを嵌入する、という技術的手段を講じた。In order to solve the above-mentioned problems, the present invention provides a system in which a rotating shaft passes through a bran removal wire mesh having a porous wall, a milling roll is attached to the rotating shaft, and raw rice is sent toward the milling roll. In a rice milling machine in which a screw roll is pivoted and a funnel stand with a supply port is installed around the screw roll, a part of the rice grains is placed on the outer surface of the peripheral wall in the gap between the funnel stand and the screw roll to the side of the feed port. A technical measure was taken to insert a grooved ring with a return groove for reflux.

１精圧力の測定結果を示すグラフである。Raw rice input from the supply port is gradually put under high pressure while being sent to the milling roll side by screw rolls.
As the grains are milled slightly, frictional heat is generated, and the oil and fat inside the rice grains dissolves and wets the surface of the screw roll, causing the rice bran to adhere to the screw roll. As the rice grains are fed further and reach the vicinity of the boundary with the milling roll, the milling pressure reaches its peak. Figure 5 shows one example of a cylindrical friction rice mill that confirms this.
1 is a graph showing the measurement results of seminal force.

り、ねじＯ−ル表面への糠の付着が防止される。The rice grains in the gap between the whitening roll (stirring roll) and the bran removal wire mesh (=refining degree) are subjected to the polishing action while rotating under high pressure due to the rotation of the whitening roll and flowing in the rotational direction of the whitening roll. However, since a grooved ring with a return groove is fitted in the gap between the screw roll and the funnel base, a portion of the rice grains near the boundary between the screw roll and the whitening roll, where the polishing pressure is highest, is partially drained of water. It flows into the return groove like an overflow and is returned to the supply port side. These rice grains are rice grains that have been slightly milled after the bran layer on their surface has been peeled off by screw rolls, so they do not contain any oil or fat components.These rice grains are mixed with raw rice and transferred to the whitening roll side by screw rolls again. When the grain is sent, the bran adhering to the surface of the screw roll is removed. In this way, by constantly mixing rice grains that do not contain oil or fat components into the raw rice, adhesion of bran to the surface of the screw O-ru is prevented.

The rice bran generated in the whitening room 12 is removed by the suction force of the exhaust fan 36, which blows out from the jet ffi@9 of the stirring roll 7 through the blast hole 6 of the main shaft 5, and removes the rice bran. Leakage from the porous wall portion into the bran collecting chamber 13 leads to the bran collecting duct 15A.

As a result, the resistance lid 1-8 rotates toward and away from the discharge port 17, thereby increasing or decreasing the pressure inside the whitening chamber 12.

業を続行できる。As described above, according to the present invention, a grooved ring is fitted into the gap between the funnel base and the screw roll, and the grooved ring has a return groove formed on the peripheral wall surface of the ring to allow a portion of the rice grains to flow back toward the supply port. As a result, the rice grains from which the aWJ containing oil and fat components has been removed are circulated from the end of the screw roll, which is the highest pressure part, through the return groove to the supply port side, so that the rice grains cause slight openings on the surface of the screw roll. The adhering bran is constantly removed, and the adhesion of the bran to the screw roll can be easily prevented without the need for special conveyance means and separation equipment for rice grains and bran for cleaning. Optimal rice milling work can be continued without having to do so.
