（産業上の利用分野）
本発明は、基部に送り螺旋を有する送穀部を備え、先端
に長い精白突条を有する精白部を設けた精米ロールに玄
米を一回供給して白米にする一回搗き精米機の改良に係
わる発明である。Detailed Description of the Invention (Industrial Field of Application) The present invention provides a method for transferring brown rice once to a rice milling roll having a grain feeding section having a feeding spiral at the base and a milling section having long milling ridges at the tip. This invention relates to the improvement of a rice milling machine that grinds rice once and grinds it into polished rice.
（従来の技術） 一回搗き精米機は送穀部は短く籍白部は長い。(Conventional technology) A rice mill that grinds once has a short grain feeding section and a long loading section.
そして短い送穀部より送られる玄米を長い精白部とこれ
を囲む精白筒との間隙で搗精して除糠し、白米にする。Then, the brown rice sent from the short grain feeding section is milled in the gap between the long milling section and the milling tube surrounding it to remove bran and become white rice.
しかして北陸、東北地方の寒気が厳しく、湿気の多い地
方では、玄米は貯蔵中に表面に罎分（木！１ｍ）を滲出
する。However, in the Hokuriku and Tohoku regions, where the weather is extremely cold and humid, brown rice oozes grains (wood!1m) on its surface during storage.
このような玄米を一回搗き精米機で搗精すると、表面に
滲出した蝋分が剥離し、特に玄米供給口に接する送り螺
旋に付着し、これに玄米表面の微塵が纏絡して漸次滞積
し、やがては送り螺旋の玄米に対する摩擦力が増大し、
玄米は送り螺旋と共に回転して精白部へ移動しなくなる
。When such brown rice is milled once using a rice milling machine, the wax that oozes out on the surface peels off and adheres especially to the feed spiral in contact with the brown rice supply port, and fine dust from the surface of the brown rice becomes entangled with this and gradually accumulates. Eventually, the frictional force of the feed spiral against the brown rice increases,
Brown rice rotates with the feed spiral and does not move to the milling section.
このような弊害を除去するべく、従来は搗精時に発生し
た糠を風力又はスクリューにより送穀部に供給し、糠に
含まれる油脂により送り螺旋や送穀中の玄米の表面を潤
滑にし、送り螺旋の玄米に対する摩擦力を減少するよう
に試みるものがある。In order to eliminate such harmful effects, conventionally, the bran generated during milling is supplied to the grain feeding section by wind power or a screw, and the oil and fat contained in the bran lubricates the feeding spiral and the surface of the brown rice being fed. Some attempt to reduce the frictional force on brown rice.
（発明が解決しようとする課題）
しかしながら糠を風力により送穀部に供給すると、送穀
部を囲む送穀筒内に糠が飛散してその内壁に付着堆積し
、玄米の供給路を閉塞する欠点がある。(Problem to be Solved by the Invention) However, when bran is supplied to the grain feeding section by wind power, the bran scatters in the grain feeding cylinder that surrounds the grain feeding section and accumulates on its inner wall, blocking the brown rice supply path. There are drawbacks.
また糠をスクリューにより送穀部に供給すると、糠は薄
い破片からなるので、互いに絡み合って流動せず、送穀
部への糠の供給口を閉ざし、糠を連続して送穀部に供給
できない、という欠点がある。Furthermore, when bran is supplied to the grain feeding section using a screw, the bran is made up of thin pieces, so they intertwine with each other and do not flow, which closes the bran supply port to the grain feeding section, making it impossible to continuously supply bran to the grain feeding section. , there is a drawback.
本発明は、送穀部の終端付近または精白突条の始端付近
において互いに摩擦してやや表皮の糖分を剥離し、小糠

に着目し、その一部を再び送穀部の始端に玄米を供給す
る玄米供給路に返送し、半搗き米とその表面に付着する
小糠に含まれる油脂により送穀部に付着する部分を剥離
すると共に送り螺旋の表面を潤滑にし、玄米の送穀能力
を高めるものである。In the present invention, the grains are rubbed against each other near the end of the grain feeding section or near the starting end of the milling ridges to slightly peel off the sugar content on the surface of the grains, and the semi-pounded rice adhering to the surface of the grain as bran is removed from the grain feeding section of the rice milling roll. We focused on the fact that the part that moves to the milling part becomes stagnant and becomes high pressure, and a part of it is returned to the brown rice supply path that supplies brown rice to the starting end of the grain feeding part. The fat and oil contained in the bran peels off the part adhering to the grain feeding part and lubricates the surface of the feeding spiral, increasing the ability to feed brown rice.

A half-pounded rice inlet is provided near the starting end, and this half-pounded rice inlet is communicated with a half-pounded rice outlet provided in the brown rice supply path to the grain feeding section.

穀粒は白米となって機外に流出する。(Function) The brown rice supplied from the brown rice supply hopper to the grain feeding section of the rice milling roll rotates in a spiral shape due to the feeding spiral of the grain feeding section, and rubs against each other between the vicinity of the end of the grain feeding section and the vicinity of the beginning of the milling ridge. A part of the outer skin is peeled off, and the rice is sent to the milling section as half-pounded rice, where it is milled by long milling ridges, and the bran leaks out through the perforated milling cylinder surrounding the milling section and is discharged outside the machine. The remaining grain becomes white rice and flows out of the machine.

止する。However, in the present invention, rice grains of half-milled rice that move to the starting end of the milling section, which has milling ridges longer than the end of the grain feeding section, stagnate in this part, but in the present invention, the grains of half-milled rice move to the starting end of the milling section, which has milling ridges longer than the end of the grain feeding section. The half-pounded rice is automatically discharged from the half-pounded rice outlet to the brown rice supply path to the grain feeding section through the half-pounded rice inlet that opens near the starting end of the ridge, so that the milled rice is not milled from near the end of the grain feeding section. This prevents the stagnation and overpressure of the half-pounded rice near the starting end of the row and makes its flow smooth, and the oil and fat of the small bran adhering to the surface of the half-pounded rice supplied to the brown rice supply path 6 to the grain feeding section feeds the rice. The surface of the spiral is lubricated to peel off the part adhering to the surface of the feeding spiral together with the half-pounded rice, to prevent the deposition thereof, and to weaken the pressure caused by the stagnation of the half-pounded rice to prevent the generation of broken rice.

、という効果を生ずる。(Effects of the Invention) According to the present invention, - a part of the half-pounded rice stagnant near the end of the grain feeding section l of the rotating rice milling roll or near the start end of the milling ridge 4 is automatically removed from the suction port 5; Since it is sucked and removed, the remaining half-pounded rice can be smoothly transferred to the milling section 3 of the rice milling roll, and the half-pounded rice with small bran attached to the surface is transferred from the discharge lower to the brown rice supply path 6 to the grain feeding section 1. Since it is spit out, the oil and fat contained in the rice bran is applied to the brown rice and the surface of the feeding spiral 2, and combined with the returned half-roasted rice, it prevents the rice grains from sticking to the feeding spiral, and not only does it reliably transport the rice grains. This has the effect of alleviating the excessive pressure rise of half-pounded rice that occurs from the vicinity of the end of the grain feeding section to the vicinity of the beginning of the polishing ridge, thereby preventing the occurrence of broken rice.
