Description

本発明は、精米工程中で発生する糠中から胚芽を取り出す胚芽分離回収装置に係るものである。   The present invention relates to a germ separation and recovery apparatus for taking out germ from rice bran generated during a rice milling process.

従来、送風機の吸引風路中に一対の網目状のフィルタを直列状に配置し、直列状に配置したフィルタの間に電気式集塵体を設けた構成は、公知である（特許文献１）。
特開２００２−１１３３７６号公報 Conventionally, a configuration in which a pair of mesh filters are arranged in series in a suction air passage of a blower and an electric dust collector is provided between the filters arranged in series is well known (Patent Document 1). .
JP 2002-113376 A

前記公知例は、精米工程で既に糠と分離した後の玄米に付着している糠を除去する構成であるため、玄米に付着していた粉体の糠中から粉体の胚芽を分離させるに過ぎず、商品価値の高い「粒体の胚芽」を得ることはできないという課題がある。
即ち、精米工程中に発生する糠は、玄米の略一割の重量となるので、仮に「１屯」の玄米を精米すると「略１００Kg」単位で糠が発生し、この大量の糠から胚芽を選別するには、公知例のフィルタと集塵体により選別する構成では非常に作業効率が低いという課題がある。
換言すると、「１００Kg」単位の糠をフィルタにより処理するには、フィルタが短時間で詰まるため、作業時間が短くて作業効率が低く、メンテナンスも容易でなく、また、集塵体に集塵された胚芽の回収についても、具体的記載がなく、作業効率が低い。
したがって、公知例は、糠を分離した後の玄米に付着している糠を除去する場合に限って成立するに過ぎない。
なお、公知例の図３には、白米を落下させて糠を吸引させる構成が記載されているが、公知例は単に玄米に付着している糠を白米から分離させるために、側方から糠を吸引するだけであるから、糠と白米とを選別できても、糠あるいは白米から胚芽粒を選別することはできない。
本願は、精米工程で白米と既に分離させた大量に発生する糠から、利用価値の高い胚芽を効率よく選別して回収すると共に、整粒（白米）を発見して精米工程の不具合を早期に発見して、メンテナンスを容易にし、全体としての作業効率を向上させるように工夫したものである。 Since the known example is configured to remove the koji adhering to the brown rice that has already been separated from the koji in the rice milling process, the powdered germ is separated from the koji of the powder adhering to the brown rice. However, there is a problem that it is not possible to obtain “grain germ” with high commercial value.
In other words, the rice bran produced during the rice milling process is approximately 10% of the weight of brown rice, so if “1 屯” brown rice is milled, the rice bran is produced in units of “approximately 100 kg”, and germs are produced from this large amount of rice bran. In the sorting, there is a problem that the working efficiency is very low in the configuration of sorting using a known example filter and dust collector.
In other words, when processing soot of “100 kg” with a filter, the filter is clogged in a short time, so the work time is short, the work efficiency is low, the maintenance is not easy, and the dust is collected by the dust collector. Also, there is no specific description about the recovery of germs, and the working efficiency is low.
Therefore, a well-known example is formed only when removing the rice cake adhering to the brown rice after separating the rice cake.
In addition, although FIG. 3 of a well-known example describes a configuration in which white rice is dropped and sucked rice cake, the known example is simply a rice cake from the side in order to separate the rice cake attached to the brown rice from the white rice. However, it is not possible to sort germ grains from straw or white rice.
The present application efficiently sorts and collects high-use-value germs from the large amounts of rice that has already been separated from white rice in the rice milling process, and discovers the sizing (white rice) to prevent problems in the rice milling process early. Discovered and devised to facilitate maintenance and improve overall work efficiency.

本発明の一実施例を図面により説明すると、１は胚芽分離回収装置であり、図示は省略するが玄米を精米する一台あるいは複数台並設した精米装置の精米工程で発生した糠中の胚芽を選別分離すると共に、精米工程で本来糠に混入してはいけない整粒が混入しているのを発見するものである。
精米工程では、玄米が精白されるとき、胚芽部分が粉砕されて粉体になって糠に混入するものと、玄米粒から粒体形状のまま分離するものとがあり、本願は糠の中に混在する粒体形状の胚芽粒を選別分離させるものである。
したがって、精米工程の構成は任意であり、本来、糠には粒体形状のままの胚芽が混入するが、積極的に、玄米粒から粒体形状のままの胚芽部分も糠に混入するように構成すると、胚芽の回収効率が向上して好適である。
なお、粉体の糠も厳密には、粒子により形成され、粒体に包含されるが、本願では肉眼により一見して粒子が認識できない糠を粉体とし、肉眼により粒子と認識できる胚芽粒を粒体としている。 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a germ separation and recovery device. Although not shown in the drawings, germs in rice bran generated in the rice milling process of one or more rice milling devices arranged in parallel to polished rice In addition to sorting and separating the rice, it is discovered that sizing that should not be mixed in the rice bran in the milling process is found.
In the milling process, when brown rice is refined, there are two types: one that is crushed into a powder and mixed into the koji, and one that is separated from the brown rice grains in the form of granules. It separates and separates the mixed granule grains.
Therefore, the composition of the rice milling process is arbitrary. Originally, germs in the shape of granules are mixed in the rice bran, but the germ parts in the shape of granules from the brown rice grains are positively mixed in the rice bran. If constituted, the efficiency of germ collection is improved, which is preferable.
Strictly speaking, powder wrinkles are formed by particles and are included in the granules. In this application, wrinkles that cannot be recognized at a glance by the naked eye are used as powders, and germ particles that can be recognized as particles by the naked eye. It is a granule.

胚芽分離回収装置１は、四角箱状のケース（フレーム）２の上部に、前記一台あるいは複数台の精米装置から排出された糠が供給される糠搬送供給筒３の終端を接続する。
ケース２内には、粉体の糠と、糠に混入する整粒（Ｇ）および小米（Ｃ、砕粒を含む）ならびに胚芽粒（Ｈ）とを分離する一次選別装置（粉体粒体選別装置）５を設ける。一次選別装置５は、前記糠搬送供給筒３を接続したケース２の糠供給口６から、糠供給口６の反対側に対峙するように設けた糠吸引排出口７との間に、吸引選別風路（一次選別風路）Ｆを形成し、吸引選別風路Ｆにて、粉体の糠と、粒体の整粒および小米ならびに胚芽粒とを一次選別する。
８は前記糠搬送供給筒３内に設けた搬送コンベアである。 In the germ separation and recovery apparatus 1, a terminal end of a straw transporting supply cylinder 3 to which the straw discharged from the one or a plurality of rice mills is supplied is connected to an upper part of a square box-like case (frame) 2.
In case 2, there is a primary sorting device (powder granule sorting device) that separates the powdered koji, and the sized particles (G) and small rice (C, including crushed particles) and germ particles (H) mixed in the koji. ) 5 is provided. The primary sorting device 5 performs suction sorting between the soot supply port 6 of the case 2 connected to the soot conveyance supply cylinder 3 and the soot suction discharge port 7 provided so as to face the opposite side of the soot supply port 6. An air passage (primary sorting air passage) F is formed, and in the suction sorting air passage F, powdery cocoons, granule sizing and small rice and germ grains are primarily sorted.
Reference numeral 8 denotes a transfer conveyor provided in the basket transfer supply cylinder 3.

前記一次選別装置５は、比重により重い順に落下することを利用して糠中の整粒と小米と胚芽粒とを落下させる一次選別落下口１０により形成し、一次選別落下口１０を前記吸引選別風路Ｆ内に形成する。
一次選別落下口１０は、ケース２の左右側板９と、左右側板９に固定した前側流下板１２と後側流下板１３とにより形成した一次誘導樋１４の上部に開口しているが、構成は任意である。
一次選別落下口１０の下方の糠供給口６に近い側は整粒落下流路１５になり、糠吸引排出口７側を胚芽落下流路１６になり、整粒落下流路１５と胚芽落下流路１６の中間は小米砕米落下流路１７となって、粉体と粒体とを選別するのみならず、糠供給口６に近い側を落下する整粒と、糠吸引排出口７側に落下する胚芽と、中間に落下する小米・砕米とにも分離させる作用を期待する。 The primary sorting device 5 is formed by a primary sorting dropping port 10 that drops sized grains in rice cake, small rice, and germ grains using falling in descending order by specific gravity, and the primary sorting dropping port 10 is sucked and sorted. It is formed in the air path F.
The primary sorting and dropping port 10 opens to the upper part of the primary guide rod 14 formed by the left and right side plates 9 of the case 2, the front falling plate 12 fixed to the left and right side plates 9, and the rear flowing plate 13. Is optional.
The side close to the cocoon supply port 6 below the primary sorting and dropping port 10 is a sized particle dropping flow channel 15, and the cocoon suction and discharging port 7 side is a germ falling channel 16, and the sized particle dropping channel 15 and the embryo falling flow are In the middle of the path 16 is a small rice broken rice falling flow path 17, which not only sorts powder and granules, but also sizing particles that fall on the side close to the soot supply port 6 and falls to the soot suction discharge port 7 side. Expected to be separated into germs that fall and small rice / crushed rice that falls between them.

また、前側流下板１２と後側流下板１３は、落下した胚芽粒を集める作用も期待し、下方に至るに従い前側流下板１２と後側流下板１３との間隔が狭くなるように形成しているが、要件ではない。
また、一次選別落下口１０で分離した胚芽が他と混合しないように、各流路を仕切る仕切板１８を、整粒落下流路１５と小米砕米落下流路１７との間、および、小米砕米落下流路１７と胚芽落下流路１６との間に夫々に設けると、一層、選別精度が向上して好適である。 In addition, the front-side falling plate 12 and the rear-side falling plate 13 are also formed so that the distance between the front-side falling plate 12 and the rear-side falling plate 13 becomes narrower as it goes down, expecting the action of collecting the dropped germ grains. Is not a requirement.
Moreover, the partition plate 18 which divides each flow path is provided between the sized particle fall flow path 15 and the small rice-crushed rice fall flow path 17 and the small rice-crushed rice so that the germ separated at the primary sorting drop opening 10 does not mix with others. Providing each between the drop channel 17 and the germ drop channel 16 is preferable because the sorting accuracy is further improved.

しかして、糠供給口６の臨むケース２内には供給された糠を一次選別落下口１０に誘導する案内傾斜板２０を設ける。
即ち、糠供給口６に対して糠吸引排出口７は相対的に低い位置に設け、吸引選別風路Ｆがケース２内を斜め下方に吹き抜けるようにして、胚芽粒の風選を効率よく行えるようにしており、糠供給口６と一次選別落下口１０の前側流下板１２との間に所定の間隔を開け、この前側流下板１２の上方に案内傾斜板２０を設ける。 Accordingly, a guide inclined plate 20 for guiding the supplied soot to the primary sorting and dropping port 10 is provided in the case 2 facing the soot supply port 6.
That is, the soot suction discharge port 7 is provided at a relatively low position with respect to the soot supply port 6 so that the suction sorting air passage F can be blown obliquely downward in the case 2 to efficiently perform the wind selection of the germ particles. In this manner, a predetermined interval is provided between the soot supply port 6 and the front flow-down plate 12 of the primary sorting drop port 10, and a guide inclined plate 20 is provided above the front flow-down plate 12.

案内傾斜板２０は、供給される糠の量や、粒体の混合率等の条件によって案内傾斜板２０の傾斜角度を調節し、風選効率を向上させている。
案内傾斜板２０の傾斜角度調節の構成は任意であるが、実施例では、案内傾斜板２０の基部に横軸２１を固定し、横軸２１をケース２に回転のみ自在に取付け、横軸２１を任意の手段（方法）により回転させて、案内傾斜板２０の先端が横軸２１中心に回動するように構成している。
この場合、ケース２の左右側板９のうち一方を透明部材により形成すると、一次選別落下口１０から落下する胚芽粒の様子が視認でき、案内傾斜板２０の傾斜角度調節や後述する風量の調節等の操作が容易になって、好適である。 The guide inclined plate 20 adjusts the inclination angle of the guide inclined plate 20 according to the conditions such as the amount of soot supplied and the mixing ratio of the granules, thereby improving the wind selection efficiency.
The inclination angle adjustment of the guide inclined plate 20 is arbitrary, but in the embodiment, the horizontal shaft 21 is fixed to the base of the guide inclined plate 20, and the horizontal shaft 21 is attached to the case 2 so as to be freely rotatable. Is rotated by an arbitrary means (method) so that the tip of the guide inclined plate 20 rotates about the horizontal axis 21.
In this case, when one of the left and right side plates 9 of the case 2 is formed of a transparent member, the state of the germ particles falling from the primary sorting dropping port 10 can be visually recognized, and the inclination angle adjustment of the guide inclined plate 20 and the air volume adjustment described later are performed. This is preferable because it is easy to operate.

しかして、前記糠吸引排出口７からは一次選別落下口１０に落下しない糠を排出するが、糠の排出を良好にするため、糠吸引排出口７と一次選別落下口１０の後側流下板１３との間に傾斜板２５を設け、糠吸引排出口７には吸引手段Ｋを接続する。
吸引手段Ｋの構成は、任意であるが、糠吸引排出口７に吸引用搬送筒２６の一端を接続し、吸引用搬送筒２６の中間部には送風機２７の吸引口２８を接続し、吸引用搬送筒２６の他端にはサイクロン２９を接続し、サイクロン２９にて搬送風と糠とを分離させる。３０は吸引圧力調節弁である。 Thus, the soot that does not fall into the primary sorting and dropping port 10 is discharged from the soot suction and discharging port 7, but in order to make the soot discharged well, the rear falling plate of the soot suction and discharging port 7 and the primary sorting and dropping port 10. 13 is provided with an inclined plate 25, and suction means K is connected to the heel suction / discharge port 7.
The configuration of the suction means K is arbitrary, but one end of the suction transport cylinder 26 is connected to the soot suction discharge port 7, and the suction port 28 of the blower 27 is connected to the middle part of the suction transport cylinder 26 to perform suction. A cyclone 29 is connected to the other end of the transfer cylinder 26 and the cyclone 29 separates the conveying wind and the soot. Reference numeral 30 denotes a suction pressure control valve.

したがって、胚芽分離回収装置１は、案内傾斜板２０の傾斜および糠吸引排出口７からの吸引風により粉体の糠と整粒および胚芽粒等との粒体を一次選別し、後述する二次選別装置３１により粒体の中から整粒と胚芽粒とを選別するように構成する。   Therefore, the germ separation and recovery apparatus 1 primarily sorts the particles of the powdered wrinkles, the sized particles, the germ particles, and the like with the inclination of the guide inclined plate 20 and the suction air from the wrinkle suction / discharge port 7, and will be described later. The sorting device 31 is configured to sort the sized and germ particles from the granules.

しかして、前記二次選別装置３１は、前記一次誘導樋１４の下部の排出口３２の下方に、整粒より小なる目合いの網体により形成した整粒選別体３３を設け、整粒選別体３３により整粒を選別回収し、精米工程における整粒の漏れを発見し、次に、胚芽と小米とを選別する二次風選部３４を設けて構成する。
前記二次風選部３４は、胚芽と小米より小なる目合いの網体により形成した胚芽選別体３５を前記整粒選別体３３の下方に所定間隔を置いて設け、胚芽選別体３５の終端（下端）下方には、小米と胚芽とが自重落下する風量の二次選別風路Ｓを形成し、二次選別風路Ｓでは更に小米と胚芽とを比重選別するように構成する。 Thus, the secondary sorting device 31 is provided with a sized sorting body 33 formed by a mesh body having a mesh size smaller than the sized grain, below the discharge port 32 below the primary guide rod 14, and sized sorting. The body 33 sorts and collects the sized particles, finds the sizing leakage in the rice milling process, and then provides and configures a secondary wind sorting section 34 that sorts the germ and small rice.
The secondary wind sorting unit 34 provides a germ sorting body 35 formed by a mesh body having a mesh size smaller than that of germ and small rice at a predetermined interval below the sized sorting sort 33, and ends the germ sorting body 35. (Lower end) Below the secondary sorting air path S of the air volume in which the small rice and the germ fall by their own weight, the secondary sorting air path S is configured to further sort the specific gravity of the small rice and the germ.

二次選別風路Ｓは、胚芽選別体３５の終端（下端）下方に送風口３６を設けて構成し、送風口３６には送風機（図示省略）の送風ホース３７を接続する。二次選別風路Ｓの下方には二次選別落下口３８を設ける。二次選別落下口３８は二次誘導樋３９の上部に形成し、二次誘導樋３９の上部または前記胚芽選別体３５の下面に送風ホース３７を取付ける。   The secondary sorting air path S is configured by providing a blower port 36 below the terminal end (lower end) of the germ sorting body 35, and a blower hose 37 of a blower (not shown) is connected to the blower port 36. A secondary sorting drop port 38 is provided below the secondary sorting air passage S. The secondary sorting drop port 38 is formed in the upper part of the secondary guide rod 39, and the blower hose 37 is attached to the upper part of the secondary guide rod 39 or the lower surface of the germ sorter 35.

二次選別風路Ｓでは、胚芽選別体３５から二次選別落下口３８に落下する胚芽と小米に送風口３６から選別風を当てて、比重の重い小米を手前に落下させ、比重の軽い胚芽を遠くに飛ばして二次選別する。
しかして、整粒選別体３３および胚芽選別体３５は一端を高く、他端を低く傾斜させると、整粒選別体３３および胚芽選別体３５で流下中に選別でき、連続作業が行えて好適である。 In the secondary sorting air passage S, the sorting wind is applied from the blower opening 36 to the germ and the small rice that fall from the germ sorting body 35 to the secondary sorting dropping port 38, and the small specific rice is dropped to the near side, and the germ having a light specific gravity is dropped. To the second order by skipping.
Therefore, if the one end of the sized particle sorting body 33 and the embryo sorting body 35 is inclined at a high end and the other end is inclined low, the sized particle sorting body 33 and the embryo sorting body 35 can be selected during the flow, which is suitable for continuous operation. is there.

また、整粒選別体３３および胚芽選別体３５は、振動モータ４０等により常時微振動するようにすると、整粒選別体３３および胚芽選別体３５からの胚芽および糠の落下が良好になって、好適である。
しかして、二次誘導樋３９の形状は任意であるが、二次誘導樋３９には小米落下流路４１と胚芽落下流路４２とを形成し、小米落下流路４１の下方には小米回収シュート４３を設け胚芽落下流路４２の下方には胚芽回収シュート４４を設ける。
また、二次誘導樋３９には、二次選別落下口３８で分離した胚芽に小米が混合しないように、各流路を仕切る仕切板４５を、小米落下流路４１と胚芽落下流路４２との間に設けると、一層、選別精度が向上して好適である。 In addition, if the sized sorting body 33 and the germ sorting body 35 are always finely vibrated by the vibration motor 40 or the like, the fall of the germ and the cocoon from the sized sorting body 33 and the embryo sorting body 35 becomes good, Is preferred.
The shape of the secondary guide rod 39 is arbitrary, but a small rice drop channel 41 and a germ drop channel 42 are formed in the secondary guide rod 39, and the small rice recovery channel 41 is disposed below the small rice drop channel 41. A chute 43 is provided, and a germ collection chute 44 is provided below the germ drop channel 42.
Further, the secondary guide rod 39 is provided with a partition plate 45 for partitioning each flow path so that the small rice is not mixed with the germ separated at the secondary sorting drop opening 38, and the small rice drop flow path 41 and the germ fall flow path 42. If it is provided in between, the sorting accuracy is further improved, which is preferable.

しかして、一次選別装置５は吸引選別風路Ｆ内に設ける都合上、実施例では、ケース２内を略密閉した空間となるように構成し、ケース２の所定位置にはケース内圧力調節用のケース内圧力調節弁４６を複数適宜の箇所に設けている。
また、前記二次選別装置３１は、二次風選部３４の二次選別風路Ｓからの微風の送風で小米と胚芽とを選別分離するようにしているので、必ずしも、ケース２内に設置する必要はないが、異物混入防止のため、好ましくは、ケース内に設置すると良い。
５１は前記整粒選別体３３の終端が臨む整粒回収シュートである。 Therefore, in order to provide the primary sorting device 5 in the suction sorting air passage F, in the embodiment, the case 2 is configured to be a substantially sealed space, and the case 2 has a predetermined position for adjusting the pressure in the case. A plurality of in-case pressure control valves 46 are provided at appropriate positions.
Further, since the secondary sorting device 31 sorts and separates the small rice and the germ by blowing a slight breeze from the secondary sorting air passage S of the secondary wind sorting section 34, it is not necessarily installed in the case 2. It is not necessary to do this, but it is preferable to install it in a case in order to prevent contamination.
Reference numeral 51 denotes a sizing collection chute facing the terminal end of the sizing selector 33.

（実施例の作用）
精米装置を駆動して、玄米を精白し、白米と糠とを分離し、精米装置から排出された糠を搬送して胚芽分離回収装置１のケース２内に糠搬送供給筒３から供給する。
ケース２の一方側には、糠搬送供給筒３の糠を供給する糠供給口６を形成し、ケース２の他方側にはケース２内を吸引する糠吸引排出口７を形成し、糠供給口６と糠吸引排出口７との間に粉体の糠は通過するが粒体の胚芽粒は自重落下する風量の吸引選別風路Ｆを形成し、吸引選別風路Ｆで糠と胚芽粒とを選別分離する一次選別装置５を設けているから、糠供給口６から吸引供給された被処理物のうち糠は吸引選別風により飛ばされて一次選別落下口１０上を通過してそのまま糠吸引排出口７から排出され、その後、粉体の糠は吸引用搬送筒２６内を通ってサイクロン２９にて搬送風と分離されて回収され、糠より比重が重い整粒および胚芽粒等の粒体は一次選別装置５の一次選別落下口１０内に自重で自然落下する。 (Operation of Example)
The rice milling device is driven to whiten the brown rice, separate the white rice from the rice bran, convey the rice cake discharged from the rice milling device, and supply it from the rice bran conveyance supply cylinder 3 into the case 2 of the germ separation and recovery device 1.
On one side of the case 2, a heel supply port 6 for supplying the heel of the heel conveyance supply cylinder 3 is formed, and on the other side of the case 2, a heel suction discharge port 7 for sucking the inside of the case 2 is formed. The powdered soot passes between the mouth 6 and the soot suction discharge port 7, but the germ particles of the granules form a suction sorting air passage F having an air volume that falls by its own weight. The primary sorting device 5 for sorting and separating the soot is provided, so that the soot that is sucked and supplied from the soot supply port 6 is blown off by the suction sorting wind and passes through the primary sorting and dropping port 10 and remains as it is. After being discharged from the suction discharge port 7, the powdered cocoons pass through the suction conveyance cylinder 26 and are separated from the conveying air by the cyclone 29 and collected. The body naturally falls by its own weight into the primary sorting and dropping port 10 of the primary sorting device 5.

したがって、一次選別装置５にて、粉体である糠と整粒および粒体である胚芽粒等とを分離させる。
また、吸引選別風路Ｆには、糠供給口６から供給された被処理物を誘導する案内傾斜板２０が設けられ、案内傾斜板２０は傾斜角度調節自在に構成しているから、胚芽粒が一次選別落下口１０内に落下し、糠は糠吸引排出口７から吸引されるように、案内傾斜板２０の傾斜角度を調節できて、一層、胚芽粒の選別効率向上させる。 Therefore, the primary sorting device 5 separates the wrinkles that are powder from the sized and germ particles that are granulated.
Further, the suction sorting air path F is provided with a guide inclined plate 20 for guiding the object to be processed supplied from the straw supply port 6, and the guide inclined plate 20 is configured to be adjustable in inclination angle. Can be adjusted into the primary sorting dropping port 10 and the inclination angle of the guide inclined plate 20 can be adjusted so that the cocoon can be sucked from the sputum suction / discharge port 7, thereby further improving the efficiency of sorting the germ particles.

即ち、一次選別落下口１０の糠供給口６側には粒体のうち主として整粒が落下し、一次選別落下口１０の糠吸引排出口７側には主として胚芽粒が落下するので、この胚芽粒の落下を基準に、案内傾斜板２０の傾斜角度を調節すると、一層、胚芽粒の選別効率向上させる。
この場合、ケース２には、適宜の箇所に複数のケース内圧力調節弁４６を設けているから、ケース内圧力調節弁４６および吸引圧力調節弁３０により吸引選別風路Ｆの風量および風力等を調節できるので、案内傾斜板２０の傾斜角度調節と相俟って、最適な選別状態に調節する。 That is, the sized granules mainly fall on the side of the primary sorting drop 10 on the side of the straw supply port 6 and the germ particles fall mainly on the side of the primary sorting drop 10 on the side of the straw suction outlet 7. When the inclination angle of the guide inclined plate 20 is adjusted based on the drop of the grains, the efficiency of selecting the germ grains is further improved.
In this case, the case 2 is provided with a plurality of in-case pressure control valves 46 at appropriate locations, so that the amount of air in the suction sorting air passage F, the wind force, and the like are controlled by the in-case pressure control valve 46 and the suction pressure control valve 30. Since it can be adjusted, it is adjusted to the optimum sorting state in combination with the inclination angle adjustment of the guide inclined plate 20.

しかして、一次選別落下口１０の糠供給口６側には一次選別装置５で粉体から分離された粒体のうち主として整粒が流下し、一次選別落下口１０の糠吸引排出口７側には主として胚芽粒が流下し、中間の一次選別落下口１０では小米・砕米が流下するが、落下する整粒および胚芽粒には、一部小米・砕米が夫々混入する。
そのため、二次選別装置３１により粒体の中から胚芽粒を選別する。
二次選別装置３１は、一次選別装置５の排出口３２の下方に、所定長さを有する整粒選別体３３を設けているから、排出口３２から供給された整粒と胚芽粒と小米等の粒体のうちの小米および胚芽粒は整粒選別体３３から落下させ、整粒は整粒選別体３３から落下させないで整粒選別体３３上を流下させて分離して整粒回収受樋５１に回収する。 Thus, the sized particles out of the particles separated from the powder by the primary sorting device 5 flow down to the side of the primary sorting dropping port 10 on the side of the soot supply port 6, and the side of the primary sorting dropping port 10 on the side of the soot suction discharge port 7. In the middle primary sorting drop 10, small rice / crushed rice flows down, but some of the small sized rice and broken rice are mixed in the falling sized and germinated grains.
Therefore, the germ particles are selected from the particles by the secondary selection device 31.
Since the secondary sorting device 31 is provided with a sized sorting body 33 having a predetermined length below the discharge port 32 of the primary sorting device 5, the sized particles, germ grains, small rice, etc. supplied from the discharge port 32. Of these grains, small rice and germ grains are dropped from the sized sorter 33, and the sized particles are dropped from the sized sorter 33 without being dropped from the sized sorter 33, and separated and collected. Recover to 51.

精米工程では、精白された白米（整粒）と糠とは、本来、別々に回収されるから、このとき、精米機の一部の破損等の原因で糠中に整粒が混入しても、従来では、糠と共に廃棄していたが、本願では、糠中に混入した整粒も整粒選別体３３で容易に回収できるので、整粒回収受樋５１を所定時間（期間）ごとに点検すると、精米機の不具合等の原因で糠中に整粒が混入しているのを発見でき、直ちに、精米工程のメンテナンスを行える。   In the milling process, milled white rice (sized rice) and rice bran are originally collected separately, so even if the granulated particles are mixed in the rice bran due to partial damage of the rice milling machine, etc. In the present application, the sized particles collected in the candy can be easily collected by the sized particle sorting body 33. Therefore, the sized particle collection receptacle 51 is inspected every predetermined time (period). Then, it can be found that the sized particles are mixed in the rice bran due to a malfunction of the rice mill and the rice milling process can be immediately maintained.

この場合、整粒選別体３３は、整粒より小なる目合いの網体により形成しているから、粒体中の小米および胚芽は落下させるが、整粒は整粒選別体３３上を流下させて分離回収するので、連続作業が可能であり、作業効率を向上させる。
しかして、胚芽と小米は、整粒選別体３３から胚芽選別体３５上に落下し、傾斜する胚芽選別体３５上を流下しているときに、胚芽と小米に付着している糠は胚芽選別体３５から落下し、胚芽選別体３５から落下しない胚芽と小米は、胚芽選別体３５の下端から二次選別落下口３８に落下する。 In this case, since the sized particle sorter 33 is formed of a mesh having a mesh size smaller than the sized particle, the small rice and the germ in the granule are dropped, but the sized particle flows down on the sized particle sorter 33. Therefore, continuous work is possible and the work efficiency is improved.
Thus, when the germ and the small rice fall from the sized sorting body 33 onto the embryo sorting body 35 and flow down on the inclined germ sorting body 35, the wrinkles adhering to the germ and the small rice are germ sorting. The germ and small rice that fall from the body 35 and do not fall from the germ sorter 35 fall from the lower end of the germ sorter 35 to the secondary sort drop port 38.

胚芽選別体３５の下端下方には二次風選部３４が設けられているから、整粒選別体３３から落下した胚芽と小米とは、二次風選部３４により比重選別され、胚芽粒に混入している小米は、二次風選部３４により除去されるので、一層、胚芽粒の選別精度を向上させられる。
この場合、二次風選部３４は、胚芽と小米より小なる目合いの網体により形成した胚芽選別体胚芽選別体３５を前記整粒選別体３３の下方に所定間隔を置いて設け、胚芽選別体３５の下端下方には、二次選別落下口３８を形成し、該二次選別落下口３８に向けて送風する送風口３６を設けて構成しているから、二次選別落下口３８から落下する胚芽と小米のうち、比重の重い小米は手前に落下し、比重の軽い胚芽を遠くに飛ばして二次選別する。 Since the secondary wind selection unit 34 is provided below the lower end of the germ sorting body 35, the germ and the small rice dropped from the sized sorting body 33 are subjected to specific gravity sorting by the secondary wind sorting unit 34, and the germ particles are separated. Since the mixed small rice is removed by the secondary wind selection unit 34, the selection accuracy of germ grains can be further improved.
In this case, the secondary wind sorting unit 34 provides a germ sorting body germ sorting body 35 formed by a mesh body having a mesh size smaller than that of germ and small rice at a predetermined interval below the granulated sorting body 33. Since the secondary sorting drop port 38 is formed below the lower end of the sorting body 35 and the air blowing port 36 for blowing air toward the secondary sorting drop port 38 is provided, the secondary sorting drop port 38 Among the falling germ and small rice, the small rice with the higher specific gravity falls to the front, and the lighter specific germ is blown away and subjected to secondary selection.

したがって、粒径で選別しにくい小米と胚芽であっても、風選による比重選別により選別するので、選別精度が向上し、しかも、目詰まりもなく、連続作業が可能であり、作業効率を向上させる。
以上のように、一次選別装置５と二次選別装置３１とにより、二段階で風選するので、粒径で選別しにくい小米と胚芽であっても、精度の高い選別が行える。 Therefore, even small rice and germs, which are difficult to sort by particle size, are sorted by specific gravity sorting by wind separation, so the sorting accuracy is improved and continuous operation is possible without clogging, improving work efficiency. Let
As described above, since the primary sorting device 5 and the secondary sorting device 31 perform wind selection in two stages, even small rice and germ that are difficult to sort by particle size can be sorted with high accuracy.

しかして、二次選別落下口３８は、二次選別落下口３８から落下する胚芽および小米を誘導する二次誘導樋３９の上部に形成し、二次誘導樋３９には小米落下流路４１と胚芽落下流路４２とを形成し、小米落下流路４１の下方には小米回収シュート４３を設け、胚芽落下流路４２の下方には胚芽回収シュート４４を設けているから、小米は小米落下流路４１から小米回収シュート４３を通って回収され、胚芽は胚芽落下流路４２から胚芽回収シュート４４を通って回収される。   Thus, the secondary sorting drop port 38 is formed on the upper part of the secondary guide rod 39 for guiding the germ and the small rice falling from the secondary sort drop port 38, and the secondary guide rod 39 has a small rice drop channel 41 and A small rice recovery chute 43 is provided below the small rice drop flow channel 41, and an embryo recovery chute 44 is provided below the germ drop flow channel 42. It is recovered from the path 41 through the small rice recovery chute 43 and the germ is recovered from the germ drop channel 42 through the germ recovery chute 44.

この場合、二次誘導樋３９では、胚芽選別体３５の下端に近い側の小米落下流路４１に小米が落下し、胚芽選別体３５の下端の遠い側の胚芽落下流路４２に胚芽粒が落下するので、二次誘導樋３９の小米落下流路４１と胚芽落下流路４２との間に仕切板４５を設けると、一層、選別精度が向上して好適である。   In this case, in the secondary guide rod 39, the small rice drops in the small rice drop channel 41 on the side close to the lower end of the embryo sorter 35, and the germ particles in the germ fall channel 42 on the far side of the lower end of the embryo sorter 35. Therefore, if the partition plate 45 is provided between the small rice drop channel 41 and the germ drop channel 42 of the secondary guide rod 39, the sorting accuracy is further improved.

また、整粒選別体３３および胚芽選別体３５は、振動モータ４０等により選別中に微振動するようにすると、整粒選別体３３からの胚芽の落下が良好になって、好適である。
また、一次選別落下口１０で分離した胚芽が他と混合しないように、各流路を仕切る仕切板１８を、整粒落下流路１５と小米砕米落下流路１７との間、および、小米砕米落下流路１７と胚芽落下流路１６との間に夫々に設け、各排出口の下方に、前記二次選別装置３１を夫々設けると、選別精度が向上して好適である。
この場合、実施例では、同じ構成の二次選別装置３１を３個設けているが、整粒選別体３３を一部省略して設けてもよい。 In addition, it is preferable that the sized sorting body 33 and the germ sorting body 35 are finely vibrated during sorting by the vibration motor 40 and the like, because the fall of the germ from the sized sorting body 33 becomes good.
Moreover, the partition plate 18 which divides each flow path is provided between the sized particle fall flow path 15 and the small rice-crushed rice fall flow path 17 and the small rice-crushed rice so that the germ separated at the primary sorting drop opening 10 does not mix with others. It is preferable that the secondary sorting device 31 is provided between the drop channel 17 and the germ drop channel 16 and the secondary sorting device 31 is provided below each discharge port so that the sorting accuracy is improved.
In this case, in the embodiment, three secondary sorting devices 31 having the same configuration are provided, but the sized sorter 33 may be partially omitted.
