Description

本発明は、利用客が持参した玄米を利用料金の投入に応じて精米処理するコイン精米機に関するものであり、さらに詳しくは、精米機の後工程に乾式の無洗米処理機を配設し、利用客の選択によって無洗米又は無洗米処理しない普通精米の両方に利用できるコイン精米機に関するものである。   The present invention relates to a coin rice milling machine that processes brown rice brought by the user according to the input of a usage fee, and more specifically, a dry-type non-washing rice processing machine is disposed in the subsequent process of the rice milling machine, The present invention relates to a coin rice mill that can be used for both washing-free rice and ordinary rice that is not washed without treatment.

近年、炊飯前に米を研ぐ必要が無く、そのまま炊飯可能な無洗米が使用されるようになってきた。しかし、無洗米はスーパーや米穀店でしか販売しておらず、一般消費者の利用が増加傾向にあるコイン精米機において、利用客の選択によって無洗米に仕上げることができるコイン精米機が望まれている。このため、特許文献1には自家の玄米を無洗米に加工処理することを可能にしたコイン精米機の実施例が開示されているが、無洗米の製造方法が具体的に明示されていなかった。   In recent years, it is not necessary to sharpen rice before cooking rice, and washing-free rice that can be cooked as it is has come to be used. However, non-washed rice is sold only at supermarkets and rice grain stores, and a coin-milling machine that can be washed-free according to the choice of customers is desired for coin milling machines that are increasingly used by general consumers. ing. For this reason, Patent Document 1 discloses an example of a coin milling machine that enables processing of unpolished brown rice into washing-free rice, but the method for producing washing-free rice has not been clearly specified. .

従来の無洗米の製造方法としては、加水精米仕上げ方式、特殊加工仕上げ方式、乾式研米仕上げ方式の三方法がある。加水精米仕上げ方式とは、精米された白米を水で洗米して白米表面に残っている糠層を洗い流し、その直後に脱水及び乾燥させて白米から水分を除去して無洗米に仕上げる方法である。特殊加工仕上げ方式とは、精米された白米にわずかに加水し、白米表面の糠を軟化させ剥離しやすい状態にした上で、特殊な糠付着剤を混入・撹拌し、白米表面の糠層を糠付着剤に吸着させた後、白米と糠付着剤を分離選別して無洗米に仕上げる方法である。乾式研米仕上げ方式とは、精米された白米の表面をブラシ等で磨いて糠層を除去して無洗米に仕上げる方法である。   There are three conventional washing-free rice production methods: a water-polished rice finishing method, a special processing finishing method, and a dry polishing rice finishing method. The water-polished rice finishing method is a method in which polished white rice is washed with water to wash away the rice bran layer remaining on the surface of the white rice, and immediately after that, dehydrated and dried to remove moisture from the white rice and finish it into non-washed rice. . The special processing finish method is to slightly add water to the polished white rice, soften the surface of the white rice surface, make it easy to peel, mix and stir a special rice bran adhesive, This is a method in which, after adsorbing to the koji adhering agent, the white rice and the koji adhering agent are separated and selected to finish them without washing. The dry-type polished rice finishing method is a method in which the surface of polished white rice is polished with a brush or the like to remove the cocoon layer and finish to wash-free rice.

加水精米仕上げ方式及び特殊加工仕上げ方式の装置では、加水精米仕上げ方式においては水を大量に使用し、また、特殊加工仕上げ方式においては糠付着剤を使用するため、機械設備が高額で大型化すると共にメンテナンス上の負担も大きいため、限られたスペースのコイン精米機の建屋内に内するには無理がある。また、白米に余分な水分が吸収されるため、白米にカビが発生する等衛生上の管理が必要になり、ランニングコストも高くなる。 In the machine for the polished rice finishing method and the special processing finishing method, a large amount of water is used in the hydrofinishing rice finishing method, and the slag adhering agent is used in the special processing finishing method. together for greater burden on the maintenance, to the built-in to the building of the coin rice mill of the limited space, it is impossible. In addition, since excess water is absorbed by the white rice, hygiene management such as generation of mold in the white rice is necessary, and the running cost is increased.

一方、乾式研米仕上げ方式の装置であれば、水を使用しないため機械設備の小型化が図られ、コストも上記の二方式に比べると安価となり、メンテナンス上の負担も軽減することができる。また、この乾式研米仕上げ方式の装置をコイン精米機の白米排出口部分に流路切換手段を介して配置することにより、建屋の機械室内に収納可能となり、従来のコイン精米機を大きく改造することなく応用できると共に、小スペース且つコストも抑えることができる。
特開2003−24804号公報
On the other hand, if the apparatus is a dry-type polished rice finishing method, water is not used, so that the mechanical equipment can be downsized, the cost is lower than the above two methods, and the maintenance burden can be reduced. In addition, by placing this dry-type polished rice finishing device at the white rice outlet of the coin rice mill through the flow path switching means, it can be stored in the machine room of the building, greatly remodeling the conventional coin rice milling machine. It can be applied without any problem, and a small space and cost can be reduced.
Japanese Patent Laid-Open No. 2003-24804

しかし、乾式研米仕上げ方式で処理された無洗米は、加水精米仕上げ方式及び特殊加工方式で処理された無洗米と比較すると、白米表面部に付着している糠層は除去できるものの、図11(a)(b)に示すように白米表面部に存在する縦溝線(凹溝部)88に入り込んでいる糠層までは完全に除去することができないため、無洗米としての質が低下するという問題があった。   However, the washed rice treated with the dry-type polished rice finishing method can remove the rice bran layer adhering to the surface of the white rice as compared with the washed rice treated with the hydrofinished rice finishing method and the special processing method, but FIG. As shown in (a) and (b), it is impossible to completely remove the ridge layer entering the longitudinal groove line (concave groove portion) 88 existing in the surface portion of the white rice, so that the quality as non-washed rice is reduced. There was a problem.

また、コイン精米機の場合、利用客が持参する玄米の品種や生産年度といった品質面や重量も特定できないため、高品質に仕上げる乾式の無洗米処理機でなければ品質の良い均一な無洗米に仕上げることができない問題もあった。   In addition, in the case of coin rice mills, the quality and weight of brown rice varieties and production years brought by customers cannot be specified. There was also a problem that could not be finished.

更に、コイン精米機の利便性である短時間に精米可能であることから、無洗米処理に長い時間を掛けることができず、精米された白米を乾式の無洗米処理機の機内を一回通すだけで、縦溝線88の糠まで完全に除去した無洗米に短時間で仕上げる必要がある。   Furthermore, since it is possible to polish rice in a short time, which is the convenience of a coin milling machine, it is not possible to take a long time for the washing-free rice treatment, and the milled white rice is passed through the dry washing-free rice treatment machine once. Therefore, it is necessary to finish the washing-free rice that has been completely removed up to the ridges of the flutes 88 in a short time.

そこで本発明は、上記事情に基づいてなされたものであり、利用客が持参した玄米を利用客の選択により普通精米又は無洗米の両方に処理することができることに加えて、無洗米に処理する場合に、白米を機内に一回通すだけで白米表面部の縦溝線(凹溝部)に入り込んでいる糠層まで完全に除去することができる乾式の無洗米処理機を内蔵したコイン精米機を提供することを目的とする。   Then, this invention is made | formed based on the said situation, and in addition to being able to process the brown rice which the user brought into both normal polished rice or non-washed rice by selection of a user, it processes to non-washed rice In this case, a coin rice mill with a built-in dry-type non-washing rice processing machine that can completely remove the rice bran layer that has entered the vertical groove line (concave groove) on the surface of the white rice by passing the rice once in the machine. The purpose is to provide.

上記目的を達成するために、本発明のうち請求項1記載の発明は、建屋を仕切壁で客室と機械室に区画し、機械室には、客室の玄米投入口より投入された玄米を機械室に取り込む搬送装置と、石抜き機と、昇降機と、精米機と、を備え、客室に備えた操作盤の制御により、取り込まれた玄米を精米処理した後に客室側の白米タンクへ排出するコイン精米機において、前記精米機の出口側には、流路切換手段を介して乾式の無洗米処理機を配設し、該乾式の無洗米処理機は、回転駆動手段によって回転する回転軸と、該回転軸の下部及び上部に設けられ、白米を該回転軸の一端側から他端側へ移送する移送体と、前記回転軸の両移送体の間複数個装着される研磨ブロックと、該研磨ブロックの外周側に該研磨ブロックと所定の間隔を隔てて設けられた円筒状の多孔部材と、を備え、前記研磨ブロックは、白米を前記回転軸の一端側から他端側へ移送する移送体と、各移送体により移送される白米の表面を研磨する円筒状の研磨ブラシからなり、乾式の無洗米処理機の出口側には、無洗米処理された白米を白米タンクに排出する排出手段を備えていることを特徴とする。 In order to achieve the above object, the invention according to claim 1 of the present invention divides a building into a guest room and a machine room with a partition wall, and the machine room is provided with machined brown rice introduced from the brown rice inlet of the guest room. Coin that is transported into the room, a stone remover, an elevator, and a rice mill, and that is discharged into the white rice tank on the guest room side after the processed brown rice is processed by the control of the operation panel provided in the guest room In the rice mill, on the outlet side of the rice mill, a dry-type non-washing rice processing machine is disposed via a flow path switching unit, and the dry-type non-washed rice processing machine has a rotating shaft that is rotated by a rotation driving unit, provided in the lower portion and upper portion of the rotary shaft, and a transfer member for transferring the polished rice from one end of the rotary shaft to the other end, a polishing block that will be a plurality mounted between both the conveying member of the rotary shaft, the set apart the polishing block at a predetermined distance on the outer peripheral side of the polishing block And a cylindrical porous member that is, the polishing block has a transfer member for transferring the polished rice from one end of the rotary shaft to the other end, a cylindrical polishing the surface of the polished rice to be transported by the transporting body consists Jo polishing brush, the outlet side of the non-bran rice processor dry, you characterized by comprising a discharge means for discharging the pre-washed rice processed rice in rice tank.

ここで流路切換手段とは、白米の流路を白米タンクと乾式の無洗米処理機とに切り換える手段を全て含める概念であり、例えば白米の自然流下を利用して流路を切り換える装置であってもよいし、流路切換機能と搬送機能を兼ね備えた装置にしてもよく、また、単数の装置から構成してもよいし、複数個の装置を組み合わせて構成してもよい。研磨ブラシと多孔部材相互の間に設けた間隔については、研磨ブラシの研磨作用が過度になって白米表面に傷がつくことを防ぐためにも、白米の厚みよりも僅かに広い隙間にすることが望ましい。乾式の無洗米処理機の移送体に関しては、回転軸の一端側から他端側に白米を搬送することが可能であれば特に限定しないが、簡単な構成で白米を確実に搬送するためにも螺旋体にすることが望ましい。排出手段とは、乾式の無洗米処理機によって無洗米処理された白米を白米タンクに排出する手段を全て含める概念であり、例えば管路や、昇降機のような搬送機能を兼ね備えたもの等を挙げることができる。   Here, the flow path switching means is a concept that includes all means for switching the white rice flow path to the white rice tank and the dry-type non-washing rice processing machine. For example, the flow path switching means is a device that switches the flow path using the natural flow of white rice. Alternatively, it may be a device having both a flow path switching function and a transfer function, or may be constituted by a single device or a combination of a plurality of devices. The spacing provided between the polishing brush and the porous member should be slightly wider than the thickness of the white rice in order to prevent the polishing action of the polishing brush from becoming excessive and scratching the surface of the white rice. desirable. The transfer body of the dry-type washing-free rice processing machine is not particularly limited as long as it can transport white rice from one end side to the other end of the rotating shaft, but also to reliably transport white rice with a simple configuration. It is desirable to use a spiral. The discharging means is a concept that includes all means for discharging the white rice that has been washed with a dry-type washing-free rice processing machine into a white rice tank, and includes, for example, a pipe or a function that has a transport function such as an elevator. be able to.

このように構成することで、精米機によって精米された白米が流路切換手段によって乾式の無洗米処理機に供給され、その白米が移送体によって回転軸の一端側から他端側へと送られていき、その途中の多孔部材の配置位置において、回転軸によって回転する研磨ブラシにより白米表面が研磨され、最後に白米タンクに排出されることで、無洗米処理された白米を得るものである。このとき、研磨ブラシの部分では白米の移送速度が低下するため、白米の表面は研磨ブラシの研磨作用を受けやすくなる。また、複数個の研磨ブラシにより白米が繰り返し研磨される。   By comprising in this way, the white rice polished by the rice mill is supplied to the dry-type washing-free rice processing machine by the flow path switching means, and the white rice is sent from one end side of the rotating shaft to the other end side by the transfer body. The white rice surface is polished by a polishing brush rotated by a rotating shaft at the position of the porous member in the middle, and finally discharged into a white rice tank, thereby obtaining white rice that has been washed without washing. At this time, since the transfer speed of the white rice is reduced in the polishing brush portion, the surface of the white rice is easily subjected to the polishing action of the polishing brush. Further, white rice is repeatedly polished by a plurality of polishing brushes.

本発明のうち請求項2記載の発明は、前記研磨ブロックと前記多孔部材との間隔が米粒の厚みより僅かに広いことを特徴とする。The invention according to claim 2 of the present invention is characterized in that an interval between the polishing block and the porous member is slightly wider than a thickness of the rice grain.

本発明のうち請求項記載の発明は、研磨ブラシのブラシ材は、直径0.05mm〜0.5mmで、長さが3mm〜30mmの樹脂製の線材を基材に密生させたものであることを特徴とする。ここで、白米表面を過度に研磨しないようにするためにも、研磨ブラシの毛足は長くしてブラシが白米表面に柔らかく当たるようにすることが望ましく、ブラシ1本当たりの直径は0.2mm〜0.3mm、長さは11mm〜13mm程度が好適な値となる。ブラシ材の材質としては、樹脂製であれば特に限定するものではないが、機械的強度及び製造のし易さを考慮して、66ナイロン(ナイロンは商標)、フッ素樹脂、ポリプロピレン、ポリブチレンテレフタレート(PBT)、ポリフェニレンサルファイド(PPS)、アクリル等を用いることが望ましい。 The invention according to claim 3 of the present invention is that the brush material of the polishing brush has a diameter of 0.05 mm to 0.5 mm and a resin wire having a length of 3 mm to 30 mm densely formed on the base material. It is characterized by that. Here, in order not to excessively polish the surface of the white rice, it is desirable to lengthen the bristle of the polishing brush so that the brush softly touches the surface of the white rice, and the diameter per brush is 0.2 mm. The preferred value is about 0.3 mm and the length is about 11 mm to 13 mm. The material of the brush material is not particularly limited as long as it is made of resin, but in consideration of mechanical strength and ease of manufacture, 66 nylon (nylon is a trademark), fluororesin, polypropylene, polybutylene terephthalate It is desirable to use (PBT), polyphenylene sulfide (PPS), acrylic or the like.

本発明のうち請求項記載の発明は、白米が前記研磨ブラシと共に旋回することを防止するための抵抗体を、多孔部材の内周面に設けたことを特徴とする。 According to a fourth aspect of the present invention, a resistor for preventing white rice from turning with the polishing brush is provided on the inner peripheral surface of the porous member.

本発明のうち、請求項1記載の発明によれば、精米機の出口に流路切換手段を介して乾式の無洗米処理機を設けることにより、1つのコイン精米機において普通精米処理と無洗米処理の両方に利用することが可能であると共に、無洗米処理を行う際に、大量の水や特殊な有機物を使用しないことから、衛生的でメンテナンス上の負担が軽減されると共に、装置の小型化を図ることが可能となり、従来のコイン精米機を大きく改造することなく低コストに乾式の無洗米処理機を内蔵することができる。また、乾式の無洗米処理機が回転軸に移送体と研磨ブラシからなる研磨ブロックを複数個配列する構成であるため、白米表面が研磨ブロックの配列分だけ繰り返し研磨作用を受けることから、最後の研磨ブロックの研磨ブラシを通過するまでの間、つまり乾式の無洗米処理機内を一回通すだけで、白米の縦溝線(凹溝部)に入り込んだ糠も完全に除去した無洗米を仕上げることが可能となり、非常に優れた乾式の無洗米処理機を内蔵したコイン精米機を提供することができる。 According to the first aspect of the present invention, by providing a dry-type non-washing rice processing machine at the outlet of the rice polishing machine via the flow path switching means, ordinary rice processing and non-washing rice in one coin rice polishing machine. It can be used for both treatments, and since it does not use a large amount of water or special organic substances when performing washing-free rice treatment, it reduces the burden on hygiene and maintenance, and reduces the size of the equipment. This makes it possible to incorporate a dry-type rice-free rice processing machine at a low cost without greatly modifying the conventional coin rice milling machine. In addition, since the dry-type non-washing rice processing machine is configured to arrange a plurality of polishing blocks consisting of a transfer body and a polishing brush on the rotating shaft, the surface of the white rice is repeatedly subjected to the polishing action by the arrangement of the polishing blocks . Until it passes through the polishing brush of the polishing block , that is, only once through the dry-type non-washing rice processing machine, it can finish the non-washing rice that completely removes the wrinkles that have entered the vertical groove line (concave groove) of white rice. This makes it possible to provide a coin milling machine incorporating a very good dry-type non-washing rice processing machine.

本発明のうち、請求項2記載の発明によれば、研磨ブロックと多孔部材との間の隙間を米粒の厚みより僅かに広くすることで、多孔部材に無理な押圧力が加わることなく、白米表面に傷をつけることも防止できる。Of the present invention, according to the invention described in claim 2, by making the gap between the polishing block and the porous member slightly wider than the thickness of the rice grains, white rice is not applied to the porous member without excessive pressing force. It is also possible to prevent the surface from being scratched.

本発明のうち、請求項記載の発明によれば、研磨ブラシの外周を移送する個々の白米を万遍なく研磨することができる。 Of the present invention, according to the invention described in claim 3 , it is possible to uniformly grind individual white rice transported on the outer periphery of the polishing brush.

本発明のうち、請求項記載の発明によれば、白米が多孔部材の内周面を旋回することを抑制して、白米が研磨ブラシと一緒に旋回することを防ぐことが可能となるため、白米の旋回速度が低下し、白米の旋回速度と高速回転する研磨ブラシとの間に生じる回転速度差が大きくなり、白米を効率よく研磨することができる。また、白米の旋回速度が低下することによって、白米表面に傷がつくことを防止することができ、品質の良い無洗米を提供することが可能となる。 According to the invention described in claim 4 among the present invention, it is possible to prevent the white rice from turning together with the polishing brush by suppressing the white rice from turning around the inner peripheral surface of the porous member. The whirling speed of the white rice decreases, and the rotational speed difference generated between the whirling speed of the white rice and the polishing brush rotating at a high speed increases, and the white rice can be polished efficiently. Moreover, it can prevent that the surface of white rice gets a damage | wound by reducing the turning speed of white rice, and it becomes possible to provide the quality non-washed rice.

以下、本発明の乾式の無洗米処理機を内蔵したコイン精米機の実施形態を図面に基づいて説明する。   Hereinafter, an embodiment of a coin milling machine incorporating a dry type non-washing rice processing machine of the present invention will be described with reference to the drawings.

図1及び図2に示すように、本発明のコイン精米機は、客室1と機械室2とに仕切壁3によって仕切った建屋4内に設置されるものであり、客室1には利用客が持参した玄米を投入する玄米投入口(玄米投入ホッパー)5と白米タンク6、操作盤7を有し、機械室2には玄米取り込みコンベヤ8と第1昇降機9、石抜き機10、第2昇降機11、精米機12、流路切換装置13、乾式の無洗米処理機(無水洗米処理機)14と、精米機12及び無水洗米処理機14から発生する糠を蓄える集糠用サイクロン15とから構成されている。   As shown in FIGS. 1 and 2, the coin milling machine of the present invention is installed in a building 4 that is partitioned into a guest room 1 and a machine room 2 by a partition wall 3. It has a brown rice inlet (brown rice input hopper) 5 for introducing the brown rice brought in, a white rice tank 6, and an operation panel 7. The machine room 2 has a brown rice intake conveyor 8, a first elevator 9, a stone remover 10, and a second elevator. 11. Consists of a rice mill 12, a flow path switching device 13, a dry-type non-washing rice treatment machine (anhydrous rice treatment machine) 14, and a collecting cyclone 15 for storing rice straw generated from the rice mill 12 and the anhydrous rice washing machine 14. Has been.

玄米投入ホッパー5は、その底部に玄米取り込みコンベヤ8を横向きに配置してある。玄米取り込みコンベヤ8は、玄米投入ホッパー5に接続したケース16内でスクリュー軸17をモータで回転させるものである。ケース16は、上流側が断面U字状で下流側が筒状に形成してあり、上流側から取り込んだ玄米を、スクリュー軸17の回転で下流側に送り、高低差によって管路K1を経て第1昇降機9の下部の受入口に流し込む。   The brown rice input hopper 5 has a brown rice intake conveyor 8 disposed in the lateral direction at the bottom. The brown rice take-in conveyor 8 rotates the screw shaft 17 with a motor in a case 16 connected to the brown rice charging hopper 5. The case 16 has a U-shaped cross section on the upstream side and a cylindrical shape on the downstream side. The brown rice taken from the upstream side is sent to the downstream side by the rotation of the screw shaft 17, and the first is passed through the pipe line K1 by the height difference. Pour into the lower entrance of the elevator 9.

第1昇降機9は、玄米を引き上げるバケットコンベヤで、上下のプーリ18,18に掛け渡したベルト19に、玄米を汲み取る多数のバケット20を間隔をあけて取り付けてある。玄米を汲み取ったバケット20は、上昇から下降に転ずる際に上側のプーリ18に沿って回転することによって、玄米を管路K2に放り投げる。   The first elevator 9 is a bucket conveyor that pulls up brown rice, and a large number of buckets 20 for pumping brown rice are attached to a belt 19 spanned between upper and lower pulleys 18 and 18 at intervals. The bucket 20 that has drawn the brown rice rotates along the upper pulley 18 when turning from rising to lowering, thereby throwing the brown rice into the pipe K2.

石抜き機10は、その上部にホッパー21を有し、ホッパー21の下端側には、高さ方向に傾斜した選別板22が揺動可能に支持され、選別板22の下方にはファン23が配置してある。選別板22は全周面に亘って多数の孔(図示省略)を有する。選別板22が傾斜された状態で揺動しながら、選別板22の下から上に向かってファン23からの風が吹き抜けると、石くずと玄米との比重差によって石くずが沈み、選別板22の揺動によってその石くずが選別板22の上方に集まり、玄米投入ホッパー5の奥側に設けられた玄米検出センサ(図示省略)が投入された玄米がなくなることを検出し、一定時間の経過を待って、選別板22の上方に有する石抜きゲート24を開くと、石くずが落下し、第1切換弁25、管路K3を経て回収箱26に回収される。そして、石くず落下後に第1切換弁25を切り換えると、石くずが取り除かれた選別板22に残った少量の玄米(残留玄米)が、管路K4を経て第2昇降機11の受入口に送られる。一方、風によって玄米は選別板22上で僅かに浮き上がって、後から供給された玄米に押されて選別板22の傾斜に沿って下流に送られて落下する。落下した玄米は出口27に設けた管路K5を経て第2昇降機11の下部の受入口に送られる。   The stone remover 10 has a hopper 21 at the upper portion thereof, and a sorting plate 22 inclined in the height direction is supported on the lower end side of the hopper 21 so as to be swingable. A fan 23 is located below the sorting plate 22. It is arranged. The sorting plate 22 has a large number of holes (not shown) over the entire circumferential surface. When the wind from the fan 23 blows from the bottom to the top of the sorting plate 22 while swinging in a state where the sorting plate 22 is tilted, the stone waste sinks due to the specific gravity difference between the stone waste and the brown rice, and the sorting plate 22 The rock waste gathers above the sorting plate 22 due to the swinging of the rice, and it is detected that the brown rice to which the brown rice detection sensor (not shown) provided at the back side of the brown rice throwing hopper 5 is thrown out disappears. When the stone gate 24 provided above the sorting plate 22 is opened, the stone waste falls and is collected in the collection box 26 through the first switching valve 25 and the pipe line K3. Then, when the first switching valve 25 is switched after the debris is dropped, a small amount of brown rice (residual brown rice) remaining on the sorting plate 22 from which the debris has been removed is sent to the receiving port of the second elevator 11 via the pipe K4. It is done. On the other hand, the brown rice is slightly lifted on the sorting plate 22 by the wind, is pushed by the brown rice supplied later, is sent downstream along the inclination of the sorting plate 22 and falls. The fallen brown rice is sent to the receiving port at the lower part of the second elevator 11 through the pipe K5 provided at the outlet 27.

第2昇降機11は第1昇降機9とほぼ同じ構造となっており、石抜き機10から送られた玄米は、第2昇降機11の受入口に取り込まれ、第2昇降機11で引き上げられ、管路K6を経て精米機12のホッパー28に送られる。   The second elevator 11 has substantially the same structure as the first elevator 9, and the brown rice sent from the stone removing machine 10 is taken into the receiving port of the second elevator 11 and pulled up by the second elevator 11, and the pipeline It is sent to the hopper 28 of the rice mill 12 through K6.

精米機12は図3に示すように、上部にホッパー28を有し、ホッパー28の下に搗精室29を接続してある。搗精室29には搗精ロール30と除糠アミ31を内装しており、玄米は搗精室29内を回転する搗精ロール30で送られるうちに、搗精室29の出口32を抵抗板33が加圧しながら塞いである状態では、玄米同士の摩擦と除糠アミ31の網目に擦られることで白米と糠を分離する。搗精室29の下方には糠回収ダクト34の先部を接続し、糠回収ダクト34の途中の部屋には除糠ファン35が内されており、モータで除糠ファン35を回し、除糠ファン35の吸引作用によって糠は除糠アミ31の網目を通過し、糠回収ダクト34の末端に接続した集糠用サイクロン15に回収される。一方、残った白米は、搗精室29の出口32に向かうが、抵抗板33がバネ36の弾力性を利用して出口32を塞いであり、搗精ロール30によって送り込まれた白米が抵抗板33を弾性力に逆らって押し込んで出口32を開き、出口32を通過した白米がケース排出口37に送られる。ケース排出口37には第2切弁38を設け、白米タンク6に通じる管路K7と、第2昇降機11の受入口に通じる管路K8と無水洗米処理機14に通じる管路K9とに流路を切り換える流路切換装置13とに分岐してある。流路切換装置13は、無水洗米処理機14に通じる管路K9を開く状態に切り換えて、精米された白米を無水洗米処理機14に送るために用いると共に、精米の開始段階や終了段階では精米が不十分になるので、第2昇降機11の受入口に通じる管路K8を開く状態に切り換えて、玄米を循環させるために用いる。なお、ホッパー28の下部には精米センサ39を設けて、精米センサ39が玄米を検出した場合には、搗精ロール30を回転させて精米し、検出しない場合は搗精ロール30の回転を停止する。また、ホッパー28の上部にはオーバーフローセンサ40を設けて、オーバーフローセンサ40が玄米を検出した場合には、操作盤7内の制御装置で玄米取り込みコンベヤ8の駆動を停止し、オーバーフローセンサ40が玄米を検出しない場合には、玄米取り込みコンベヤ8の回転を継続する。 As shown in FIG. 3, the rice mill 12 has a hopper 28 at the top, and a milling chamber 29 is connected below the hopper 28. The milling chamber 29 is provided with a milling roll 30 and a scouring net 31. While the brown rice is fed by the milling roll 30 rotating in the milling chamber 29, the resistance plate 33 pressurizes the outlet 32 of the milling chamber 29. However, in the closed state, the white rice and rice bran are separated by rubbing between the unpolished rice and rubbing on the mesh of the dehulled net 31. Below the pearling chamber 29 connects the front portion of the bran collecting ducts 34, in the middle of the room bran collecting duct 34 are a built is Jonuka fan 35, turning the bran removing fan 35 by the motor, bran removing As a result of the suction action of the fan 35, the soot passes through the mesh of the soot 31 and is collected in the collecting cyclone 15 connected to the end of the soot collecting duct 34. On the other hand, the remaining white rice goes to the exit 32 of the scouring chamber 29, but the resistance plate 33 closes the exit 32 using the elasticity of the spring 36, and the white rice fed by the scouring roll 30 blocks the resistance plate 33. It pushes against the elastic force to open the outlet 32, and the white rice that has passed through the outlet 32 is sent to the case outlet 37. The case discharge port 37 provided with the second changeover valve 38, and conduit K7 leading to white rice tank 6, to a conduit K9 leading to conduit K8 anhydride RICE processor 14 leading to the receiving port of the second elevator 11 It branches off to the flow path switching device 13 for switching the flow path. The flow path switching device 13 is used to switch the open state of the pipe K9 leading to the anhydrous rice washing machine 14 to send the polished white rice to the anhydrous rice washing machine 14, and at the start and end stages of the rice polishing. Is used to circulate brown rice by switching to a state where the pipe K8 leading to the receiving port of the second elevator 11 is opened. A rice milling sensor 39 is provided at the lower part of the hopper 28. When the rice milling sensor 39 detects brown rice, the milling roll 30 is rotated to mill the rice. Otherwise, the milling roll 30 stops rotating. Further, an overflow sensor 40 is provided on the upper part of the hopper 28. When the overflow sensor 40 detects brown rice, the control of the operation panel 7 stops the drive of the brown rice intake conveyor 8, and the overflow sensor 40 turns the brown rice. Is not detected, the brown rice intake conveyor 8 continues to rotate.

上述した抵抗板33の開閉構造をさらに詳細に説明する。精白度の調整及び玄米を排出するために、搗精室29の出口近傍にアーム41をその中央部を支点として揺動可能に支持し、アーム41の一端部を押圧手段42で押圧・解除可能に設け、アーム41の他端部に備わる抵抗板33がその押圧及び解除を利用して出口32を開閉可能に設けてある。   The opening / closing structure of the resistance plate 33 will be described in more detail. In order to adjust the degree of whitening and to discharge the brown rice, the arm 41 is supported in the vicinity of the exit of the milling chamber 29 so as to be able to swing around its center, and one end of the arm 41 can be pressed and released by the pressing means 42. A resistance plate 33 provided at the other end of the arm 41 is provided so as to be able to open and close the outlet 32 by utilizing its pressing and releasing.

押圧手段42は、バネ36の圧縮度合を変更して出口32を開閉するもので、搗精室29の外側に抵抗モータ43を配し、抵抗モータ43にネジ軸44を直結し、ネジ軸44にナット45とアーム41の一端部を間隔をあけてねじ込み、ネジ軸44に通したバネ36をナット45とアーム41の一端部との間に介在し、ナット45をその周方向に回転不能に保持することによって、ネジ軸44の正転又は逆転に伴ってナット45を前進・後退可能に設けてある。従って、バネ36の圧縮度合いの変更は、操作盤7の操作信号に基づいて抵抗モータ43を回転し、ネジ軸44の回転に伴ってナット45を前進・後退することによって行われる。その制御の為に、ネジ軸44の端部に凸部46を設けると共に、凸部検出センサ47をその周囲に設け、そのセンサ47から得られる情報に基づいて抵抗モータ43の回転回数を制御する。また、バネ36の圧縮度合いの最小、最大を決定する為に、ナット45に被検出物48を突出し、リミットスイッチからなる前進限スイッチ49、後退限スイッチ50を前後に対向して被検出物48の移動範囲を規制してある。バネ36の圧縮度合いが最小の場合は、バネ36が全く伸縮しておらずナット45が後退限の位置にあり、バネ36の押圧力が解除されて抵抗板33を開いて、抵抗板33と出口32との間に隙間を形成し、隙間から玄米をそのまま排出する。そして、この後退限の位置を原点として、ナット45を前進させることによって、バネ36の圧縮度合い、ひいては抵抗板33が出口32を塞ぐ方向にかかる押圧力を増大し、その押圧力に応じて精白度合いが決定する。   The pressing means 42 changes the degree of compression of the spring 36 and opens and closes the outlet 32. A resistance motor 43 is disposed outside the squeezing chamber 29, and a screw shaft 44 is directly connected to the resistance motor 43. The nut 45 and one end of the arm 41 are screwed at an interval, and a spring 36 passed through the screw shaft 44 is interposed between the nut 45 and one end of the arm 41 so that the nut 45 is not rotatable in the circumferential direction. Thus, the nut 45 can be moved forward and backward as the screw shaft 44 rotates forward or backward. Therefore, the compression degree of the spring 36 is changed by rotating the resistance motor 43 based on the operation signal of the operation panel 7 and moving the nut 45 forward and backward as the screw shaft 44 rotates. For this control, a convex portion 46 is provided at the end of the screw shaft 44 and a convex portion detection sensor 47 is provided around the end, and the number of rotations of the resistance motor 43 is controlled based on information obtained from the sensor 47. . Further, in order to determine the minimum and maximum degree of compression of the spring 36, the detected object 48 protrudes from the nut 45, and the detected object 48 is opposed to the forward limit switch 49 and the backward limit switch 50 made up of limit switches. The movement range is regulated. When the degree of compression of the spring 36 is minimum, the spring 36 is not expanded or contracted at all, and the nut 45 is in the retreat limit position, the pressing force of the spring 36 is released, and the resistance plate 33 is opened. A gap is formed between the outlet 32 and the brown rice is discharged as it is from the gap. Then, by moving the nut 45 forward with the position of the retreat limit as the origin, the degree of compression of the spring 36, and consequently the pressing force applied in the direction in which the resistance plate 33 closes the outlet 32 is increased, and the whitening is performed according to the pressing force. The degree is determined.

流路切換装置13は、図4に示すように横送りコンベヤであり、横向きケース51内でスクリュー軸52を回転可能に設け、ケース51の長手方向の中央部分に投入口53を有し、ケース51の左右に落下口54をそれぞれ設け、第2昇降機11の受入口に通じる管路K8と無水洗米処理機14に通じる管路K9にそれぞれ接続してある。モータでスクリュー軸52を正転させた場合には、第2昇降機11の受入口に通じる管路K8に玄米を落下させ、モータを逆転させた場合には、無水洗米処理機14に通じる管路K9に白米を落下させる。   As shown in FIG. 4, the flow path switching device 13 is a transverse feed conveyor, and a screw shaft 52 is rotatably provided in a laterally oriented case 51, and has a charging port 53 at the center in the longitudinal direction of the case 51. Drop ports 54 are provided on the left and right sides of 51, respectively, and are connected to a pipeline K 8 that leads to the receiving port of the second elevator 11 and a pipeline K 9 that leads to the anhydrous rice washing machine 14. When the screw shaft 52 is rotated forward by the motor, the brown rice is dropped to the conduit K8 leading to the receiving port of the second elevator 11 and when the motor is reversed, the conduit leading to the anhydrous rice washing machine 14 Drop the white rice on K9.

無水洗米処理機14は、本発明者が以前に出願(特願2003−376509)した乾式無洗米製造装置をコイン精米機内に設置可能なように構成にしたものであり、図5及び図6に示すように、機体ケース55内の縦方向に回転軸56を回転自在に設け、その近傍にモータ57を設置し、回転軸56の下端に設けた伝導手段58を介して回転軸56を回転駆動させる。回転軸56の下方側には白米を上方へ移送する揚米螺旋59を設け、その上方には、図7に示すような白米を上方へ移送するリードを有する短いブラシ螺旋60と、樹脂製のブラシ(ブラシの直径:0.2mm〜0.3mm、ブラシの長さ:11mm〜13mm)を高密度に植毛し、ほぼ円筒状に形成した研磨ブラシ61と組み合わせた研磨ブロック62が複数個装着してある。さらにその上方には白米を上方へ移送する排出螺旋63を設けてある。揚米螺旋59の外周には適宜隙間を隔てて円筒状の揚米円筒64を設け、その下端側には機体ケース55外側のホッパー65と通じる開口部66を有し、これと同様に排出螺旋63の外周にも円筒状の排出円筒67を設け、その上方に設けた出口68には白米タンク6に通じる管路K10を設けてある。また、揚米円筒64と排出円筒67の間には、研磨ブロック62の外周と米粒の厚みより僅かに広い隙間を隔ててスリット状の多孔部材からなる円筒状の除糠金網69を設け、図8(a)(b)に示すように除糠金網69の内面には研磨ブロック62の回転方向と直交するように凸状の抵抗体70を複数本等間隔に設けてある。除糠金網69の外周部にあたる機体ケース55内部には、仕切壁で囲まれた除糠室71を形成し、除糠室71の下方には肌糠回収ダクト72の先部を接続し、肌糠回収ダクト72の末端は除糠ファン35の吸気側の精米機12に接続してある糠回収ダクト34(図1及び図3参照)に接続してあり、除糠ファン35の吸引作用によって、白米表面部の縦溝線88から除去された粒子の細かい肌糠は除糠金網69の網目を通過し、精米機12からの糠と混合されながら糠回収ダクト34の末端に接続した集糠用サイクロン15に回収される。除糠室71の外周には外気を取り入れる空気穴(図示省略)を肌糠回収ダクト72の対向位置に形成してあり、除糠金網69の外周に沿って空気の流れを生じさせて、除糠金網69の外周に付着しやすい肌糠も完全に回収させる。   The anhydrous rice-washing machine 14 is configured such that a dry-type non-washing rice production apparatus previously filed by the present inventor (Japanese Patent Application No. 2003-376509) can be installed in a coin milling machine. As shown in the figure, a rotary shaft 56 is rotatably provided in the longitudinal direction in the body case 55, a motor 57 is installed in the vicinity thereof, and the rotary shaft 56 is driven to rotate via a conduction means 58 provided at the lower end of the rotary shaft 56. Let A lifted rice spiral 59 for transferring white rice upward is provided below the rotary shaft 56, and a short brush spiral 60 having a lead for transferring white rice upward as shown in FIG. A plurality of polishing blocks 62 in combination with a polishing brush 61 in which brushes (brush diameter: 0.2 mm to 0.3 mm, brush length: 11 mm to 13 mm) are densely implanted and are formed in a substantially cylindrical shape are mounted. It is. Further above that, a discharge spiral 63 for transferring the white rice upward is provided. A cylindrical raised rice cylinder 64 is provided on the outer periphery of the raised rice spiral 59 with an appropriate gap, and an opening 66 communicating with the hopper 65 on the outer side of the machine body case 55 is provided on the lower end side thereof. A cylindrical discharge cylinder 67 is also provided on the outer periphery of 63, and an outlet 68 provided above the discharge cylinder 67 is provided with a pipe line K 10 that leads to the white rice tank 6. Further, between the raised rice cylinder 64 and the discharge cylinder 67, there is provided a cylindrical metal mesh 69 made of a slit-like porous member with a gap slightly wider than the outer circumference of the polishing block 62 and the thickness of the rice grains. As shown in FIGS. 8 (a) and 8 (b), a plurality of convex resistors 70 are provided at equal intervals on the inner surface of the metal strip 69 so as to be orthogonal to the rotational direction of the polishing block 62. A body removal chamber 71 surrounded by a partition wall is formed inside the machine body case 55 corresponding to the outer periphery of the removal wire mesh 69, and a front portion of the skin recovery duct 72 is connected to the lower portion of the removal chamber 71, The end of the soot recovery duct 72 is connected to the soot recovery duct 34 (see FIGS. 1 and 3) connected to the rice mill 12 on the intake side of the soot removal fan 35. The fine skin cocoon removed from the vertical groove line 88 on the surface of the white rice passes through the mesh of the culling wire mesh 69 and is mixed with the cocoon from the rice milling machine 12 and connected to the end of the cocoon recovery duct 34. It is collected in the cyclone 15. An air hole (not shown) for taking outside air is formed in the outer periphery of the removal chamber 71 at a position opposed to the skin recovery duct 72, and an air flow is generated along the outer periphery of the removal metal mesh 69 to remove the air. Skin wrinkles that easily adhere to the outer periphery of the wire mesh 69 are also completely recovered.

無水洗米処理機14のホッパー65に供給された白米は、揚米円筒64内に流れ込み、揚米螺旋59によりブラシ螺旋60、研磨ブラシ61の順で上方に送られる。研磨ブラシ61自体は、樹脂製のブラシが高密度に植毛されているため揚米機能はほとんどない。そのため、研磨ブラシ61の周囲では、揚米方向への移動速度が低下して白米の表面は研磨ブラシ61の研磨作用を受けやすくなる。そのため、高速で回転する研磨ブラシ61との速度差が大きく生ずることで、研磨ブラシ61によるブラッシング効果が上がることになる。また、研磨ブラシ61の周囲では白米の密度も高まり、そのため白米相互のぶつかり合いから白米自体が研磨ブラシ61の周囲に対する公転を繰り返し、白米表面の裏・表は万遍なく研磨ブラシ61による研磨作用を受けることになる。しかし、研磨ブラシ61の周囲では揚米方向の移動速度が低下しても、研磨ブラシ61の旋回につられ、白米も除糠金網69の内面を旋回してしまうと、研磨ブラシ61による研磨を充分に受けにくくなる。そこで、研磨ブラシ61の回転方向と直交するように除糠金網69の内面に凸状の抵抗体70を設け、研磨ブラシ61による研磨を充分に受けにくくなることを防止している。つまり、ブラシ螺旋60及び研磨ブラシ61につられて旋回しながら揚米されようとする白米は、まず研磨ブラシ61により揚米方向への移動速度が減速されて、また、除糠金網69の抵抗体70によって旋回方向の旋回速度も抑えられるので、研磨ブラシ61による研磨を充分に受けられることになる。   The white rice supplied to the hopper 65 of the anhydrous rice processing machine 14 flows into the raised rice cylinder 64 and is sent upward in the order of the brush spiral 60 and the polishing brush 61 by the raised rice spiral 59. The polishing brush 61 itself has almost no deep-fried rice function since resin brushes are planted at high density. Therefore, around the polishing brush 61, the moving speed in the rice lifting direction decreases, and the surface of the white rice is easily subjected to the polishing action of the polishing brush 61. For this reason, the brushing effect by the polishing brush 61 is increased due to a large speed difference from the polishing brush 61 rotating at high speed. In addition, the density of white rice is increased around the polishing brush 61. Therefore, the white rice itself repeatedly revolves around the polishing brush 61 due to the collision between the white rice, and the back and front surfaces of the white rice are uniformly polished by the polishing brush 61. Will receive. However, even if the moving speed in the rice lifting direction decreases around the polishing brush 61, if the polishing brush 61 is swung and the white rice also swirls on the inner surface of the demetalization wire net 69, the polishing by the polishing brush 61 is sufficient. It becomes difficult to receive. Therefore, a convex resistor 70 is provided on the inner surface of the metal strip 69 so as to be orthogonal to the rotation direction of the polishing brush 61 to prevent the polishing brush 61 from being sufficiently difficult to be polished. That is, the white rice that is about to be rolled while being swung by the brush helix 60 and the polishing brush 61 is first decelerated by the polishing brush 61 in the moving direction of the rice, and the resistance of the wire mesh 69 is removed. Since the turning speed in the turning direction is also suppressed by 70, the polishing by the polishing brush 61 can be sufficiently received.

本実施形態では、研磨ブロック62を回転軸56に複数個配列する構造が取られている。その結果、前述したようなブラッシングが研磨ブラシ61の配列数分繰り返し行われる。
ところで、白米の表面部には図11(a)(b)に示すような筋状の縦溝線(凹溝部)88が多数存在し、この縦溝線(凹溝部)88に入り込んだ糠を取り除くことが困難であった。しかしながら本実施形態では、ブラシ螺旋60とブラッシング効果の高い研磨ブラシ61との組み合わせで、白米全体に渡り万遍なく研磨作用を施し、また複数個の研磨ブロック62を配列してある分、同様な研磨作用を白米が繰り返し受けることで、最終段の研磨ブラシ61を通過するまでの間に縦溝線(凹溝部)88に入り込んだ糠も除去される。また、その反面、研磨作用が強すぎると、白米表面の凹凸のうち、凸部分を必要以上に研磨しすぎて表面を傷つけてしまう恐れがあった。その結果、無洗米処理後に炊飯した時に食味が低下したり、表面に傷がついたりすることで白米表面の光沢がなくなり視感も低下する等、無洗米品質が悪くなることもあった。そこで本実施形態では、研磨ブラシ61の外側と除糠金網69の内面との間の隙間を、米粒の厚みより僅かに広くすることで、白米より硬度の高い除糠金網69に無理な押圧力が加わることなく、白米表面に傷をつけることも防止できる。また、除糠金網69の内面に設けられた凸状の抵抗体70は、研磨ブラシ61の旋回に伴う白米の余分な旋回をセーブする作用を有し、これも白米表面の傷を防止する効果を有する。更に、研磨ブラシ61の毛足を長くし、白米表面を過度にブラッシングしないように柔らかく白米表面にあたるような配慮が加えてある。
In the present embodiment, a structure in which a plurality of polishing blocks 62 are arranged on the rotation shaft 56 is employed. As a result, the brushing as described above is repeated for the number of the polishing brushes 61 arranged.
By the way, there are many streaky vertical groove lines (concave groove portions) 88 as shown in FIGS. 11 (a) and 11 (b) on the surface portion of white rice, and the wrinkles that have entered the vertical groove lines (concave groove portions) 88 are formed. It was difficult to remove. However, in the present embodiment, the combination of the brush helix 60 and the polishing brush 61 having a high brushing effect provides a uniform polishing action over the entire white rice, and a plurality of polishing blocks 62 are arranged in a similar manner. By repeatedly receiving the polishing action, the rice grains that have entered the longitudinal groove line (concave groove portion) 88 before passing through the final polishing brush 61 are also removed. On the other hand, if the polishing action is too strong, among the irregularities on the surface of the white rice, there is a fear that the convex part will be excessively polished and the surface may be damaged. As a result, when the rice was cooked after the non-washing rice treatment, the quality of the non-washing rice sometimes deteriorated, for example, the taste was lowered or the surface was damaged, and the gloss of the white rice surface was lost and the visual feeling was lowered. Therefore, in this embodiment, by making the gap between the outer side of the polishing brush 61 and the inner surface of the stripping wire net 69 slightly larger than the thickness of the rice grains, an excessive pressing force is applied to the stripping wire mesh 69 that is harder than white rice. It is also possible to prevent the surface of white rice from being damaged without being added. Further, the convex resistor 70 provided on the inner surface of the metal strip 69 has an action of saving the extra turning of the white rice accompanying the turning of the polishing brush 61, and this also prevents the surface of the white rice from being damaged. Have Further, consideration is given to making the bristles of the polishing brush 61 longer and softly hitting the white rice surface so as not to excessively brush the white rice surface.

次に、本発明のコイン精米機の動作を説明する。このコイン精米機は、利用客が持参した玄米を利用客の選択により普通精米又は無洗米の両方に処理することができるものであり、まずは玄米を普通精米処理する動作について説明する。このコイン精米機には、2つの切換弁25,38と流路切換装置13、石抜きゲート24を備えており、初期状態では第1切換弁25が管路K3を開く側、第2切換弁38が流路切換装置13側、流路切換装置13が第2昇降機11側にそれぞれ米が流れるように設定してあり、石抜きゲート24は閉じられている。   Next, the operation of the coin rice mill of the present invention will be described. This coin-milling machine can process brown rice brought by a user into either normal rice or non-washed rice according to the user's selection. First, the operation of subjecting brown rice to normal rice polishing will be described. This coin mill is provided with two switching valves 25, 38, a flow switching device 13, and a stone removal gate 24. In the initial state, the first switching valve 25 opens the pipe K3, and the second switching valve. 38 is set so that rice flows to the flow path switching device 13 side and the flow path switching device 13 to the second elevator 11 side, respectively, and the stone removal gate 24 is closed.

営業中表示灯75が点灯している場合は、利用客が普通精米処理しようとする玄米量に応じてコインをコイン投入口77に投入すると、コイン枚数が料金表示灯78に表示され、同時に無洗米スイッチ79と3つの白度スイッチ80が点滅して受付可能状態となる。これを受けて利用者は玄米を玄米投入ホッパー5に投入すると共に、希望する白度スイッチ80を押す。すると精米中表示灯81が点灯し、玄米取り込みコンベヤ8、第1昇降機9、石抜き機10、第2昇降機11が駆動する。精米機12は白度スイッチ80に対応して抵抗モータ43を回転してバネ36の圧縮度合いを変更し、抵抗板33の閉鎖具合を決定すると共に、精米機12出口の第2切換弁38は流路切換装置13側が開く状態に保持し、また、流路切換装置13は第2昇降機11に向かう管路K8に搬送するようにモータを回転して、玄米や未精白米を第2昇降機11と精米機12の間で循環させるように運転が開始する。   When the business indicator lamp 75 is lit, when the user inserts a coin into the coin insertion slot 77 according to the amount of brown rice to be processed, the coin number is displayed in the charge indicator lamp 78, and at the same time there is nothing. The rice-washing switch 79 and the three whiteness switches 80 are blinked and are ready to accept. In response to this, the user puts the brown rice into the brown rice throwing hopper 5 and presses the desired whiteness switch 80. Then, the milled rice indicating lamp 81 is turned on, and the brown rice intake conveyor 8, the first elevator 9, the stone remover 10, and the second elevator 11 are driven. The rice milling machine 12 rotates the resistance motor 43 in response to the whiteness switch 80 to change the compression degree of the spring 36 to determine the closing state of the resistance plate 33, and the second switching valve 38 at the outlet of the rice milling machine 12 is The flow path switching device 13 side is held in an open state, and the flow path switching device 13 rotates the motor so as to convey it to the pipe line K8 toward the second elevator 11 so that brown rice and unpolished rice can be transferred to the second elevator 11. And the operation starts so as to circulate between the rice milling machine 12 and the rice milling machine 12.

玄米が精米機12のホッパー28に供給され、精米センサ39が玄米を検出したことを受けて、制御装置はタイマーカウントT1,T2を開始し、T1終了後、搗精ロール30及び除糠ファン35を駆動する。それに伴って精米処理が始まるが、精米初期の玄米や未精白米は、第2切換弁38及び流路切換装置13を経て第2昇降機11から再び精米機12のホッパー28に戻る。タイマーカウントT2が終了すると、精米機12出口の第2切換弁38が白米タンク6側を開くように切り換わり、管路K7を経て白米が白米タンク6に排出される。精米機12のホッパー28のオーバーフローセンサ40が満杯信号を出力した場合には、玄米取り込みコンベヤ8の駆動を停止し、オーバーフローセンサ40が非満杯信号を出力した場合には、玄米取り込みコンベヤ8の駆動を再開する。精米処理は玄米取り込みコンベヤ8が投入された玄米を全て取り込むまで継続する。   When the brown rice is supplied to the hopper 28 of the rice mill 12 and the rice milling sensor 39 detects the brown rice, the control device starts timer counts T1 and T2, and after T1, the milling roll 30 and the dehulling fan 35 are turned on. To drive. Along with this, the rice milling process is started, but brown rice and unmilled rice at the early stage of milling return to the hopper 28 of the rice mill 12 again from the second elevator 11 via the second switching valve 38 and the flow path switching device 13. When the timer count T2 ends, the second switching valve 38 at the exit of the rice mill 12 is switched so as to open the white rice tank 6 side, and the white rice is discharged into the white rice tank 6 through the pipe K7. When the overflow sensor 40 of the hopper 28 of the rice mill 12 outputs a full signal, the drive of the brown rice intake conveyor 8 is stopped. When the overflow sensor 40 outputs a non-full signal, the drive of the brown rice intake conveyor 8 is stopped. To resume. The rice milling process is continued until all of the brown rice loaded by the brown rice taking conveyor 8 is taken up.

精米機12のホッパー28の玄米量が少なくなり、精米センサ39が玄米を検出しなくなった場合は、第2切換弁38が再び流路切換装置13側を開くように切り換わり、精米機12のホッパー28内や精米機12内の残留玄米を流路切換装置13及び管路K8を経て第2昇降機11へ戻し、再び精米機12のホッパー28へ供給して、第2昇降機11と精米機12の間での循環精米を開始する。これは、精米機12への後続米がなくなると、精米機12内の圧力が低下することから、精米処理終了時の玄米や未精白米が白米タンク6に排出されて、白米タンク6内の白米と混ざることを防ぐためであり、第2昇降機11と精米機12の間を一定時間循環することで残留玄米を白米に処理するものである。循環精米終了後、再び第2切換弁38を白米タンク6側が開くように切り換えて、白米を白米タンク6に排出すると同時に、抵抗モータ43が逆回転し、ナット45が0点(原点)方向に移動を始めてバネ36の圧縮を解除し、抵抗板33を開放する。ナット45の被検出物48が後退限スイッチ50を「ON」にすると、抵抗モータ43の回転が停止すると共に、除糠ファン35が停止する。除糠ファン35が停止すると吸引作用がなくなるため、除糠アミ31の網目に残留している白米が排出されやすくなり、さらに精米機12が全体的に前傾していることから、精米機12を一定時間空運転することで残留白米を完全に白米タンク6へ排出させることができる。精米機12内の残留白米を完全に白米タンク6に排出して精米機12の空運転を終了することで、コイン精米機の運転が終了する。   When the amount of brown rice in the hopper 28 of the rice milling machine 12 decreases and the rice milling sensor 39 no longer detects brown rice, the second switching valve 38 is switched again to open the flow path switching device 13 side. Residual brown rice in the hopper 28 or the rice mill 12 is returned to the second elevator 11 via the flow path switching device 13 and the pipe K8, and is supplied again to the hopper 28 of the rice mill 12 so that the second elevator 11 and the rice mill 12 Start circulating rice milling in between. This is because when the subsequent rice to the rice milling machine 12 disappears, the pressure in the rice milling machine 12 decreases, so that brown rice and unmilled white rice at the end of the rice milling process are discharged into the white rice tank 6, This is to prevent the remaining brown rice from being mixed with the white rice, and the residual brown rice is processed into white rice by circulating between the second elevator 11 and the rice mill 12 for a certain period of time. After the circulation milling is completed, the second switching valve 38 is switched again so that the white rice tank 6 side is opened, and the white rice is discharged into the white rice tank 6. The movement is started, the compression of the spring 36 is released, and the resistance plate 33 is opened. When the object to be detected 48 of the nut 45 turns the backward limit switch 50 to “ON”, the rotation of the resistance motor 43 is stopped and the removal fan 35 is stopped. When the removal fan 35 is stopped, the suction action is lost, so that the white rice remaining in the mesh of the removal residue 31 is easily discharged, and the rice mill 12 is tilted forward as a whole. The remaining white rice can be completely discharged into the white rice tank 6 by idling for a predetermined time. Residual white rice in the rice milling machine 12 is completely discharged into the white rice tank 6 and the idle operation of the rice milling machine 12 is terminated, whereby the operation of the coin rice milling machine is completed.

ここで、玄米取り込みコンベヤ8は投入料金分だけ回転するので、投入料金よりも多い玄米を玄米投入ホッパー5に入れた場合は、玄米投入ホッパー5に玄米が残る。これを玄米投入ホッパー5に付けた玄米センサ(図示省略)が検出して、料金不足表示灯82を点灯させる。   Here, since the brown rice intake conveyor 8 rotates by the amount charged, brown rice remaining in the brown rice input hopper 5 remains when brown rice larger than the input fee is put into the brown rice input hopper 5. This is detected by a brown rice sensor (not shown) attached to the brown rice charging hopper 5, and the charge shortage indicator lamp 82 is turned on.

次に、玄米を無洗米処理する動作を説明する。ここでは、普通精米処理の場合と異なる動作についての説明に留める。コイン投入口77にコインを投入すると、無洗米スイッチ79と3つの白度スイッチ80が点滅して受付可能状態となる。これを受けて利用客は玄米を玄米投入ホッパー5に投入すると共に、無洗米スイッチ79を押す。すると、精米中表示灯81が点灯し、玄米取り込みコンベヤ8、第1昇降機9、石抜き機10、第2昇降機11、精米機12が駆動する。   Next, the operation | movement which carries out the washing-free process of the brown rice is demonstrated. Here, only the operation different from that in the case of ordinary rice processing will be described. When a coin is inserted into the coin insertion slot 77, the no-wash rice switch 79 and the three whiteness switches 80 blink to be ready for acceptance. In response to this, the user puts brown rice into the brown rice throwing hopper 5 and pushes the no-wash rice switch 79. Then, the indicator light 81 in the milled rice is turned on, and the brown rice intake conveyor 8, the first elevator 9, the stone remover 10, the second elevator 11, and the rice mill 12 are driven.

ここで、管理者パネル74の利用料金徴収スイッチ84を「可」に設定している場合は、例えば普通精米処理に加えて無洗米処理1回当たりの利用料金を100円に設定したとすると、200円以上の投入を待ってから無洗米スイッチ79が点滅して受付可能状態となる。つまり、100円の投入だけでは白度スイッチ80のみが受付可能状態となり、無洗米スイッチ79は受付不可状態となっている。200円以上の投入を確認したら無洗米スイッチ79が点灯し、無洗米スイッチ79を押すと、投入料金から1回当たりの利用料金を差し引いた料金を料金表示灯78に表示し、その表示料金分の玄米を玄米取り込みコンベヤ8で機内に取り込み無洗米処理を行う。1回当たりの利用料金は予め設定しておいてもよいし、管理者パネル74に利用料金設定スイッチ、例えば搬送量設定スイッチ85,86と同等なデジタルスイッチ等を設けて管理者が任意に設定可能にしておいてもよい。   Here, if the usage fee collection switch 84 of the administrator panel 74 is set to “permitted”, for example, if the usage fee per washing-free rice processing is set to 100 yen in addition to the ordinary rice processing, After waiting for 200 yen or more, the no-wash rice switch 79 blinks and is ready to accept. That is, only the whiteness switch 80 is in an acceptable state when only 100 yen is inserted, and the no-wash rice switch 79 is in an unacceptable state. After confirming the input of 200 yen or more, the no-wash rice switch 79 is lit, and when the no-wash rice switch 79 is pressed, a charge subtracting the charge per use from the charge is displayed on the charge indicator lamp 78, and the displayed charge The brown rice is taken into the machine by the brown rice take-in conveyor 8 and washed without washing. The usage fee per time may be set in advance, or the administrator panel 74 is provided with a usage fee setting switch, for example, a digital switch equivalent to the transport amount setting switches 85 and 86, and the administrator arbitrarily sets it. It may be possible.

精米機12は無洗米スイッチ79の信号を受けて、普通精米処理の場合と同様に、予め設定してある抵抗値まで抵抗モータ43を回転させて、抵抗板33を所定の位置まで閉鎖すると共に、玄米や未精白米が第2昇降機11と精米機12の間を一定時間循環するように、第2切換弁38と流路切換装置13が切り換わる。予め設定してある抵抗値は、普通精米の場合の上白又は標準の精白度と同等であり、抵抗値を精白度の標準以下に設定すると、精米処理後の白米表面に糠の残存が多くなり、その状態で無洗米処理を行っても白米表面から糠が完全に除去されず、品質の低下した無洗米に仕上がってしまうためである。このバネ36の圧縮度合いは予め設定してあるが、精米機の管理者が任意に設定可能なように、管理者パネル74に無洗米処理専用の精白度設定スイッチを設けてもよい。   Upon receiving the signal from the non-washing rice switch 79, the rice mill 12 rotates the resistance motor 43 to a preset resistance value and closes the resistance plate 33 to a predetermined position, as in the case of ordinary rice processing. The second switching valve 38 and the flow path switching device 13 are switched so that the brown rice and the unpolished rice circulate between the second elevator 11 and the rice mill 12 for a certain time. The resistance value set in advance is equivalent to the upper whiteness or standard milling degree in the case of ordinary milled rice, and if the resistance value is set below the standard of milling degree, a lot of rice cake remains on the polished rice surface after the milling process. Thus, even if the washing-free rice treatment is performed in that state, the wrinkles are not completely removed from the surface of the white rice, and the washed rice with a reduced quality is finished. The degree of compression of the spring 36 is set in advance, but a whiteness setting switch dedicated for washing-free rice processing may be provided on the administrator panel 74 so that the administrator of the rice milling machine can arbitrarily set it.

玄米が精米機12のホッパー28に供給され、精米センサ39が玄米を検出したことを受けて、制御装置はタイマーカウントT1,T2を開始し、T1終了後、搗精ロール30及び除糠ファン35を駆動すると同時に、無水洗米処理機14が運転を開始する。タイマーカウントT2が終了すると、流路切換装置13のモータの回転方向が逆転して、無水洗米処理機14に通じる管路K9側に白米を搬送する。そして、無水洗米処理機14によって無洗米処理された白米が管路K10を経て白米タンク6に排出される。ここで、無水洗米処理機14と白米タンク6を繋ぐ経路は、必ずしも管路K10に限定するものでなく、無水洗米処理機14と白米タンク6の間に昇降機のような搬送手段を設けてもよい。   When the brown rice is supplied to the hopper 28 of the rice mill 12 and the rice milling sensor 39 detects the brown rice, the control device starts timer counts T1 and T2, and after T1, the milling roll 30 and the dehulling fan 35 are turned on. Simultaneously with the driving, the anhydrous rice treating machine 14 starts operation. When the timer count T <b> 2 ends, the rotation direction of the motor of the flow path switching device 13 is reversed, and the white rice is conveyed to the line K <b> 9 leading to the anhydrous rice washing machine 14. Then, the white rice that has been washed with no water by the anhydrous rice treatment machine 14 is discharged to the white rice tank 6 through the pipe K10. Here, the path connecting the anhydrous rice treatment apparatus 14 and the white rice tank 6 is not necessarily limited to the pipe line K10, and a conveying means such as an elevator may be provided between the anhydrous rice treatment apparatus 14 and the white rice tank 6. Good.

精米処理は、玄米取り込みコンベヤ8が投入料金分の玄米を全て取り込み、精米機12のホッパー28の精米センサ39が玄米を検出しなくなるまで継続する。精米機12のホッパー28の玄米量が少なくなり、精米センサ39が玄米を検出しなくなった場合は、流路切換装置13のモータの回転方向を正転に戻して、精米機12内の残留玄米を管路K8を経て第2昇降機11へ戻し、第2昇降機11と精米機12の間での循環精米を開始する。これは普通精米処理と同様に、精米終了時の玄米や未精白米を無水洗米処理機14に供給することを防ぐための制御である。一定時間の循環精米が終了すると、再び流路切換装置13のモータの回転方向が逆転し、循環精米した白米を無水洗米処理機14に供給し、さらに無洗米処理された白米を白米タンク6に排出する。それと同時に、普通精米処理と同様に、抵抗モータ43が逆回転し、ナット45が0点(原点)方向に移動し始め、最終的には抵抗モータ43の回転が停止すると共に、除糠ファン35が停止する。そして、残留白米を精米機12から完全に排出して無水洗米処理機14に供給するために、一定時間精米機12の空運転を行い、その後精米機12の運転を停止する。精米機12の運転停止後、無水洗米処理機14の空運転を行い、無水洗米処理機14から完全に無洗米処理された白米を白米タンク6に排出して、無水洗米処理機14の空運転を終了することで、コイン精米機の運転が終了する。尚、無水洗米処理機14が空運転を開始すると同時に、精米機12の除糠アミ31及び無水洗米処理機14の除糠金網69周辺に付着した糠や肌糠をクリーニングする目的で、停止した除糠ファン35を再び運転させてもよい。   The rice milling process is continued until the brown rice taking conveyor 8 takes in all the brown rice for the input fee, and the rice milling sensor 39 of the hopper 28 of the rice milling machine 12 no longer detects the brown rice. When the amount of brown rice in the hopper 28 of the rice milling machine 12 decreases and the rice milling sensor 39 no longer detects brown rice, the rotational direction of the motor of the flow path switching device 13 is returned to normal rotation, and the residual brown rice in the rice milling machine 12 Is returned to the second elevator 11 via the pipe K8, and the circular rice milling between the second elevator 11 and the rice mill 12 is started. This is a control for preventing the brown rice and unmilled white rice at the end of the rice polishing from being supplied to the anhydrous washing rice processing machine 14 as in the case of the normal rice processing. When the circulation rice milling for a certain period of time is completed, the rotation direction of the motor of the flow path switching device 13 is reversed again, the circulation rice milled white rice is supplied to the anhydrous rice washing machine 14, and the unwashed rice is further fed to the white rice tank 6. Discharge. At the same time, the resistance motor 43 rotates in the reverse direction and the nut 45 starts to move in the 0 point (origin) direction, and finally the rotation of the resistance motor 43 is stopped and the fan 35 is removed as in the ordinary rice milling process. Stops. Then, in order to completely discharge the residual white rice from the rice mill 12 and supply it to the anhydrous rice washing machine 14, the rice mill 12 is idled for a certain period of time, and then the operation of the rice mill 12 is stopped. After the operation of the rice mill 12 is stopped, the anhydrous rice washing machine 14 is idled, and the completely washed rice is discharged from the anhydrous rice treating machine 14 to the white rice tank 6 and the anhydrous rice washing machine 14 is idled. By ending, the operation of the coin milling machine is completed. In addition, at the same time that the anhydrous rice washer 14 started the empty operation, it was stopped for the purpose of cleaning the wrinkles and skin wrinkles adhering to the periphery of the dehitter 31 of the rice mill 12 and the debris wire net 69 of the anhydrous rice washer 14. The removal fan 35 may be operated again.
