With such a configuration, the jack 43 is controlled by the control signal from the control unit 8, and the flow rate of the rice grains flowing into the polishing unit 2 is adjusted.
　精白部２は、研削アセンブリ２１と精白筒２２及び排出樋２３を備えている。精白筒２２は、その上部が米粒の受け口２４とされ、基部が精白部機台９に固定されている。基部の一部は切り欠かれて送り口２５となっている。研削アセンブリ２１は、竪軸２６、押さえ部材２７、研削ロール２８、ロール受け台２９を備え、竪軸２６を中心に組み付けられている。研削ロール２８、押さえ部材２７およびロール受け台２９はいずれも平面視で円形であり、中央に竪軸２６に対するボスを有している。竪軸２６は精白部機台９に対して竪方向に軸支され、２箇所の軸受け機構３０によって、スラスト方向（軸方向）に維持され、また、ラジアル方向（軸に対する回転方向）で回転可能に軸支されている。 The polishing unit 2 includes a grinding assembly 21, a polishing cylinder 22, and a discharge gutter 23. The upper part of the whitening cylinder 22 is a receiving port 24 for rice grains, and the base thereof is fixed to the whitening part machine base 9. A part of the base is cut out to form a feeding port 25. The grinding assembly 21 includes a vertical shaft 26, a holding member 27, a grinding roll 28, and a roll cradle 29, and is assembled around the vertical shaft 26. The grinding roll 28, the holding member 27, and the roll pedestal 29 are all circular in a plan view, and have a boss with respect to the vertical shaft 26 in the center. The vertical shaft 26 is pivotally supported in the vertical direction with respect to the refinement machine base 9, is maintained in the thrust direction (axial direction) by two bearing mechanisms 30, and is rotatable in the radial direction (rotational direction with respect to the shaft). It is supported by.
　竪軸２６には、ロール受け台２９が嵌挿されてボス３１の箇所で竪軸２６に固定されている。そして、上記ロール受け台２９の上に研削ロール２８がボス３２の箇所で竪軸２６に対して遊嵌（軸に対して隙間が空いて、遊びを持った状態ではめられた状態）されている。さらに、研削ロール２８の上方に押さえ部材２７がボス３３の箇所で竪軸２６に挿入されている。押さえ部材２７は、下縁が上記研削ロール２８の上面に接触するとともに、ボス３３の上方から差し込まれる留めボルト３４によって竪軸２６の上端に固定されている。以上のような構成により、研削アセンブリ２１は精白部機台９に取り付けられ、研削ロール２８は留めボルト３４によってロール受け台２９と押さえ部材２７との間に挟まれて固定される。したがって、研削アセンブリ２１は、竪軸２６とともに回転することとなる。 A roll cradle 29 is fitted into the vertical shaft 26 and fixed to the vertical shaft 26 at the position of the boss 31. Then, the grinding roll 28 is loosely fitted to the vertical shaft 26 at the position of the boss 32 on the roll cradle 29 (a state in which there is a gap with respect to the shaft and the grinding roll 28 is fitted with play). There is. Further, a pressing member 27 is inserted into the vertical shaft 26 at the position of the boss 33 above the grinding roll 28. The lower edge of the pressing member 27 is in contact with the upper surface of the grinding roll 28, and is fixed to the upper end of the vertical shaft 26 by a fastening bolt 34 inserted from above the boss 33. With the above configuration, the grinding assembly 21 is attached to the milling machine base 9, and the grinding roll 28 is sandwiched and fixed between the roll pedestal 29 and the holding member 27 by the fastening bolt 34. Therefore, the grinding assembly 21 will rotate together with the vertical shaft 26.
　精白筒２２の内面と上記研削ロール２８の外周面との間には、精白室３５が形成されており、その底部は上記ロール受け台２９の外周部分３６で閉じられている。そして、竪軸２６の下端には受動プーリー３７が固定され、モーターＭの駆動プーリーとＶベルトによって連動するように連結されている。精白筒２２の基部に設けた上記送り口２５は、万石部５へと米粒を案内する排出樋２３に対して開口しており、この開口にはエア圧式構造による圧力調整弁３８が配置されている。圧力調整弁３８は精白室３５における米粒圧力に応じて開度が変化するものであり、圧力調整弁３８のエア圧と精白筒２２への米粒の流量に応じて、後述する精白室３５の充満率が調整・制御される。 A polishing chamber 35 is formed between the inner surface of the polishing cylinder 22 and the outer peripheral surface of the grinding roll 28, and the bottom thereof is closed by the outer peripheral portion 36 of the roll cradle 29. A passive pulley 37 is fixed to the lower end of the vertical shaft 26, and is connected to the drive pulley of the motor M so as to be interlocked with the V-belt. The feeding port 25 provided at the base of the polishing cylinder 22 is open to a discharge gutter 23 for guiding rice grains to the Mangoku portion 5, and a pressure adjusting valve 38 having an pneumatic structure is arranged in this opening. There is. The opening degree of the pressure adjusting valve 38 changes according to the rice grain pressure in the whitening chamber 35, and the whitening chamber 35, which will be described later, is filled according to the air pressure of the pressure adjusting valve 38 and the flow rate of the rice grains into the whitening cylinder 22. The rate is adjusted and controlled.
　研削ロール２８は、環状の複数の部分ロールが上下に積層して一体に構成されている。
本実施形態における各部分ロールはアルミ合金製であり、各部分ロールの外周面にＣＢＮ砥粒が電着によって固定されている。従来のＧＣ砥石（焼成砥石）ではミリ単位の凹凸を無くすことや、砥石を真円に加工することが困難であったが、上記したＣＢＮ砥粒の電着砥石は、研削ロール２８の台金が機械加工品であるため、ロール本体が真円であり、研削ロール２８の表面に対して米粒の側面を向けた状態で整列させながら精米するのに適している。これにより、特に原形精白及び扁平精白を好適に行うことができる。そして、モーターＭを駆動すると受動プーリー３７を介して竪軸２６が駆動され、精白筒２２内で研削ロール２８が回転するように構成されている。 The grinding roll 28 is integrally composed of a plurality of annular partial rolls laminated one above the other.
Each partial roll in this embodiment is made of an aluminum alloy, and CBN abrasive grains are fixed to the outer peripheral surface of each partial roll by electrodeposition. With the conventional GC grindstone (firing grindstone), it was difficult to eliminate unevenness in millimeters and to process the grindstone into a perfect circle. Since is a machined product, the roll body is a perfect circle, and is suitable for milling rice while aligning it with the side surface of the rice grain facing the surface of the grinding roll 28. This makes it possible to particularly preferably perform prototype whitening and flat whitening. When the motor M is driven, the vertical shaft 26 is driven via the passive pulley 37, and the grinding roll 28 is configured to rotate in the polishing cylinder 22.
　精白部２には、貯留タンク３から受け口２４を通じて精白室３５に米粒が送り込まれ、精白筒２２と研削ロール２８との間で米粒が研削（精白）される。精白室３５を通過した米粒はロール受け台２９の外周部分３６で受け止められ、その後、送り口２５から排出樋２３に送り出される。 Rice grains are sent from the storage tank 3 to the whitening chamber 35 through the receiving port 24 into the whitening portion 2, and the rice grains are ground (whitened) between the whitening cylinder 22 and the grinding roll 28. The rice grains that have passed through the whitening chamber 35 are received by the outer peripheral portion 36 of the roll cradle 29, and then sent out from the feeding port 25 to the discharge gutter 23.
　排出樋２３に送り出された米粒と糠の混合物は、万石部５を流下しながら米粒と糠に分離され、分離された米粒は揚穀部機台１０に設置された揚穀部６によって貯留タンク３の頂部へ揚穀される。米粒はこの循環サイクルを繰り返して、所望の酒米に仕上げられる。 The mixture of rice grains and bran sent to the discharge gutter 23 is separated into rice grains and bran while flowing down the Mangoku part 5, and the separated rice grains are stored in a storage tank by the grain raising section 6 installed on the grain raising section machine stand 10. It is fried to the top of 3. The rice grains repeat this circulation cycle to produce the desired sake rice.

（その他の実施形態）
　以上、本発明の酒造用精米装置における一の実施形態について説明した。しかし、本発明は前述の実施形態に必ずしも限定されるものではなく、例えば以下のような変形例も含まれる。 (Other embodiments)
The embodiment of the rice milling apparatus for sake brewing of the present invention has been described above. However, the present invention is not necessarily limited to the above-described embodiment, and includes, for example, the following modifications.

Any one of 28C was configured to be installed in the whitening portion 2. However, the present invention is not necessarily limited to such an embodiment, and for example, as shown in FIG. 5, the rice milling apparatus 1 for brewing is provided with a plurality of milling cylinders 22 corresponding to the milled shape of the milled rice. It is also possible to configure it to.
　すなわち、精白部機台９の上部に、球形精白用ロール２８Ａを備えた精白筒２２と、原形精白用ロール２８Ｂを備えた精白筒２２と、扁平精白用ロール２８Ｃを備えた精白筒２２を全て配置する。そして、制御部８において選択された精白米の精米形状に応じて、流量調整部４から供給される米粒を、米粒振分部７０によって振り分けるように構成することも可能である。このように構成することで、酒造用精米装置１自体は大きくなるが、各種研削ロールを保管場所から運搬して精白筒２２内に設置する設備構成よりも、付帯する設備を大幅に減らして単純化することが可能となる。加えて、貯留タンク３や万石部５、揚穀部６などを複数の精白筒２２で共用することが可能となり、設備コストを抑えつつ、所望の精米形状の精白米を効率的に製造することが可能となる。 That is, the whitening cylinder 22 provided with the spherical whitening roll 28A, the whitening cylinder 22 provided with the original whitening roll 28B, and the whitening cylinder 22 provided with the flat whitening roll 28C are all located on the upper part of the whitening unit base 9.
