しかしながら、上記特許文献１の方法には玄米中のγ−アミノ酪酸を富化させる際の生産性に問題があった。すなわち、上記特許文献１の方法では、玄米を原料とするとともに一般的な米麦用循環式乾燥機を用いて、玄米に胴割れを生じないように0.2％／ｈ以下の緩慢的な加水を行うため、その加湿に係る所要時間と、その後の貯留タンク内で静置させることによってγ−アミノ酪酸を富化させる所要時間（例えば10時間）とが掛かる。また、この他、前記循環式乾燥機において、玄米中のγ−アミノ酪酸の富化処理がバッチ式で行われるために、γ−アミノ酪酸が富化した玄米を連続的に大量生産することが困難であるという問題点があった。
そこで、本願発明は、上記問題点にかんがみ、玄米に亀裂を生じることなく、γ−アミノ酪酸が富化した玄米を連続的に大量生産して生産性を向上させることのできる施設を提供することを技術的課題としたものである。 However, the method of Patent Document 1 has a problem in productivity when enriching γ-aminobutyric acid in brown rice. That is, in the method of the above-mentioned Patent Document 1, a slow hydration of 0.2% / h or less is performed using brown rice as a raw material and a general rice wheat circulation dryer so as not to cause cracking of the brown rice. Therefore, the time required for the humidification and the time required for enriching γ-aminobutyric acid by allowing it to stand in the storage tank thereafter (for example, 10 hours) are required. In addition, because the enrichment of γ-aminobutyric acid in brown rice is performed in a batch manner in the circulating dryer, continuous mass production of brown rice enriched in γ-aminobutyric acid is possible. there is a problem that Ru difficult der.
In view of the above problems, the present invention provides a facility capable of continuously mass-producing brown rice enriched with γ-aminobutyric acid to improve productivity without causing cracks in brown rice. Is a technical issue.

次に、本発明のγ−アミノ酪酸の富化穀物の製造設備１の作用について、図４のフローを参照しながら、前記三つの実施例について説明する。 Next, the operation of the manufacturing equipment 1 enriched grain γ- aminobutyric acid of the present invention, with reference to a flowchart of FIG. 4, described above three embodiments.

実施例１（生籾からギャバ富化する運転制御プログラム）：
荷受ホッパー２に荷受された高水分籾（例えば水分２４％）は、前記中央制御部２４による管理のもと、粗選機４及び計量機５を経て貯留タンク８ａに順次一次的に貯留されて、前記送風機８ｂからの送風によって通風される（ステップ１，ステップ２）。 Example 1 (operation control program for enriching from ginger):
High moisture soot (for example, 24% moisture) received by the cargo receiving hopper 2 is sequentially and temporarily stored in the storage tank 8a through the coarse selector 4 and the weighing machine 5 under the control of the central control unit 24. The air is blown by the air blown from the blower 8b (Step 1, Step 2) .

次に、前記貯留タンク８ａに一次貯留された生籾は、前記ギャバ生成装置１２に順次供給し、ギャバ生成タンク１２ａ内に堆積される。ギャバ生成タンク１２ａ内に生籾が満量まで供給されたら、その時点で前記貯留タンク８ａからの生籾の搬送供給を一旦中止するとともに、ギャバ生成タンク１２ａの各繰出しバルブ１２ｈ及び排出繰出バルブ１２ｃの各駆動を開始する。また、同じく、前記加湿温風生成供給装置１３及び吸引ファン１４の駆動を開始する。これにより、前記加湿温風生成供給装置１３で生成された加湿温風は、吸引ファン１４の吸引作用によって、加湿温風供給風胴１２ｆから各送風管１２ｄ内に供給された後に、各送風管１２ｄを構成する多孔壁の各孔から噴風されて生籾の粒間を通風して生籾を加湿した後、前記各排気管１２ｅを構成する多孔壁の各孔から各排気管１２ｅ内に吸入され、排風胴１２ｇを介して吸引ファン１４から排風される。 Next, raw rice, which is stored the primary to the storage tank 8a sequentially supplied to the GABA generator 12, is deposited on GABA generation tank 12a. When Namamomi the GABA production tank 12a is supplied to the full amount, once with stops raw paddy conveying supply from the storage tank 8a at that time, GABA respective feed valves 12h and discharged feeding valve generation tank 12a Each drive of 12c is started. Further, similarly, it starts driving of the humidifying warm air generator supplying device 13 and the suction fan 14. As a result, the humidified warm air generated by the humidified warm air generating and supplying device 13 is supplied from the humidified warm air supply wind tunnel 12f into each of the blower tubes 12d by the suction action of the suction fan 14, and then each of the blower tubes. after being air jet from the holes of the multi-hole wall that make up the 12d between raw rice grain and air humidified raw rice, the exhaust pipes from the pores of the porous walls constituting the respective exhaust pipe 12e is sucked into the 12e, is the exhaust air from the suction fan 14 through the Haifudo 12g.

初期運転（還流制御運転）：
前記ギャバ生成タンク１２ａ内の生籾は、前記加湿温風によって加湿及び加温されながら排出繰出バルブ１２ｃの駆動によって順次繰り出され、前記切換弁１６ａ及び穀物還流装置１６を介して該ギャバ生成タンク１２ａ内に還流される。このとき、生籾のγ−アミノ酪酸の富化条件として（図５の条件表参照）、前記ギャバ生成タンク１２ａ内の生籾に通風する加湿温風の温度を約７０℃で湿度９０％〜９８％とし、かつ、通風時間（タンク内滞留時間）を少なくとも２時間とするのがよい。このため、運転開始直後の初期運転においては、ギャバ生成タンク１２ａ内の下部に堆積した生籾に少なくとも２時間の通風時間（タンク内滞留時間）を与えるため、ギャバ生成タンク１２ａの大きさ及び／又は繰出し速度等（流下速度）を考慮しながら、前記生籾を、穀物還流装置１６を介してギャバ生成タンク１２ａ内に任意時間還流・循環させる。 Initial operation (reflux control operation):
The ginger in the GABA generating tank 12a is sequentially fed by driving the discharge feeding valve 12c while being humidified and heated by the humidified hot air, and the GABA generating tank 12a is passed through the switching valve 16a and the grain recirculation device 16. Is refluxed in. At this time, (see condition table in FIG. 5) as a wealth Kajo matter of raw paddy γ- aminobutyric acid, wherein the GABA generate the temperature of the humidified warm air to ventilation raw paddy tank 12a about 70 ° C. at 90% humidity It is preferable to set it to ˜98% and to set the ventilation time (retention time in the tank) to at least 2 hours. For this reason, in the initial operation immediately after the start of operation, in order to give at least 2 hours of ventilation time (residence time in the tank) to the ginger accumulated in the lower part of the GABA generation tank 12a, the size of the GABA generation tank 12a and / or Alternatively, the ginger is circulated and circulated in the GABA generation tank 12a through the grain recirculation device 16 for an arbitrary time while taking into consideration the feeding speed and the like (flowing speed ).

γ−アミノ酪酸の富化：
γ−アミノ酪酸は、籾内部の玄米に水分を付加することで、主に胚芽内に蓄積されたグルタミン酸が脱炭酸酵素によって転換・生成されるものであり、γ−アミノ酪酸の生成に適した温度・湿度の空気による玄米の加湿により胚芽中で富化（生成）されて、胚乳部に移行する。 wealth of γ- amino butyric acid:
γ- amino butyric acid, by adding a water content in the rice inside the rice, mainly are those stored glutamate in the germ is converted, generated by decarboxylase, suitable for the production of γ- aminobutyric acid was in the germ is enriched (generated) by the by that brown rice of humidification to the air temperature and humidity, and the process proceeds to the endosperm part.

連続運転：
前記初期運転を終えると、続いて、連続運転を行う。すなわち、前記初期運転によってギャバ生成タンク１２ａで２時間の循環・通風を終え、このとき水分が約２７％となった生籾（γ−アミノ酪酸が富化した籾）を排出繰出バルブ１２ｃから順次排出し、事前に切換えた前記切換弁１６ａを介して前記循環型穀物乾燥機１１に搬送供給し、乾燥運転を開始する。その一方で、ギャバ生成タンク１２aへの新たな生籾の搬送供給を再開し、γ−アミノ酪酸の富化を終えて排出された分だけ貯留タンク８ａから生籾原料をギャバ生成タンク１２ａに供給し、γ−アミノ酪酸が富化した生籾の生産を連続して行い１回の流下でγ−アミノ酪酸を富化させる。このとき、新たに供給された生籾原料が前記条件の加湿温風の通風を２時間受けることができるように各繰出しバルブ１２ｈの駆動スピードが調整され、これによって、時間当たり約２０トンのギャバ富化した生籾を製造することができる（以上がステップ３）。 Continuous operation:
When the initial operation is completed, continuous operation is subsequently performed. That is, after the circulation-air for 2 hours at GABA produced tank 12a by the initial operation, sequentially raw paddy moisture at this time was about 27% (paddy of γ- aminobutyric acid-enriched) from the discharge unwinding valve 12c It is discharged and conveyed to the circulating grain dryer 11 through the switching valve 16a switched in advance, and the drying operation is started. Meanwhile, it resumes new raw paddy conveying feed to GABA generation tank 12a, by the amount discharged after enrichment of γ- aminobutyric acid storage tank 8a or al raw rice material GABA generation tank 12a the test feed, .gamma.-aminobutyric acid causes enrichment of .gamma.-aminobutyric acid in a falling once performed continuously producing raw rice enriched. At this time, adjusts the new driving speed of the feed valve 12 h as the air humidification warm air can receive 2 h of the supplied raw rice material is the condition, thereby, of about 20 ton time A gab enriched ginger can be produced ( step 3 above ) .

なお、本発明は籾を対象としているので、前記加湿温風の通風条件が「加湿温風を温度約７０℃で湿度９０％〜９８％、かつ、通風時間（タンク内滞留時間）を少なくとも２時間」であっても、玄米の場合における胴割れ及びその後工程での砕米が生じることなく、効率よくγ−アミノ酪酸が富化した生籾を大量に生産することができる。 In addition, since the present invention is directed to the soot, the ventilation condition of the humidified warm air is “the humidified warm air is about 70 ° C. and the humidity is 90% to 98%, and the ventilation time (retention time in the tank) is at least 2. even time ", without broken rice occurs in barrel cracking and subsequent steps in the case of brown rice, efficiently γ- amino butyric Ru can produce a large amount of raw rice enriched.

こうして、前記循環型穀物乾燥機１１のタンク内にγ−アミノ酪酸の富化を終えた生籾が搬送されて所定量が張り込まれると、循環型穀物乾燥機１１は乾燥運転を開始して、水分が約１７％の、いわゆる半乾籾になるまで生籾を熱風通風しながら循環乾燥を行う（ステップ４）。 Thus, a predetermined amount raw rice is conveyed finishing the enrichment of γ- aminobutyric acid in the tank of the circulation type grain dryer 11 is Harikoma, recycling-Grain dryer 11 starts the drying operation Then, the ginger is circulated and dried with hot air until it becomes a so-called semi- dry rice cake having a water content of about 17% (step 4).

前記循環型穀物乾燥機１１において乾燥が終わると、籾を該循環型穀物乾燥機１１から排出し、前記穀物貯蔵サイロ１９に搬送して一旦貯留する（ステップ５）。そして、前記循環型穀物乾燥機１１の空き状況をみながら、前記半乾籾を前記循環型穀物乾燥機１１に搬送して水分約１５％まで仕上げ乾燥を行い、仕上げ乾燥終了後は、再度、前記穀物貯蔵サイロ１９に搬送して貯蔵する（ステップ６，ステップ７）。 When drying is completed in said circulating grain dryer 11, to discharge rice from the circulating grain dryer 11, temporarily stored in the transport to the grain storage silo 19 (Step 5). Then, while observing the availability of the circulation type grain dryer 11, the semi-dried rice cake is transported to the circulation type grain dryer 11 and finish-dried to a water content of about 15%. It is transported and stored in the grain storage silo 19 (steps 6 and 7).

上記実施例１のようにしてγ−アミノ酪酸を富化した籾について、籾摺りを行った玄米のγ−アミノ酪酸の含有量（ＧＡＢＡ値）を測定したところ、通常の玄米では２．０ｍｇ／１００ｇｄ．ｂであるものが、本実施例による玄米では１８ｍｇ／１００ｇｄ．ｂ、それを無洗米処理した米粒では１４ｍｇ／１００ｇｄ．ｂの各含有量であり、γ−アミノ酪酸の含有量が増加していることが確認された。また、本実施例による玄米又は無洗米を炊飯した米飯は、食味が良好であるが、いわゆる籾臭については多少あった（図５参照）。 About the koji enriched with γ-aminobutyric acid as in Example 1 above, the content of γ-aminobutyric acid (GABA value) of brown rice subjected to mashing was measured, and 2.0 mg / 100 gd for normal brown rice . b is 18 mg / 100 gd. for brown rice according to this example . b, 14mg / 100gd in it the pre-washed rice processing and rice grains. It was each content of b, and it was confirmed that content of ( gamma) -aminobutyric acid is increasing. In addition, the cooked rice cooked with brown rice or non-washed rice according to the present example had good taste, but there was some so-called bad smell (see FIG. 5).

上記実施例３においてγ−アミノ酪酸が富化した籾について、籾摺りを行った玄米のγ−アミノ酪酸の含有量（ＧＡＢＡ値）を測定したところ、通常の玄米では２．０ｍｇ／１００ｇｄ．ｂであるものが、本実施例による玄米では１８ｍｇ／１００ｇｄ．ｂ、それを無洗米処理にした精白米粒では１４ｍｇ／１００ｇｄ．ｂの各含有量であり、本実施例においてγ−アミノ酪酸の含有量が増加していることが確認された。また、本実施例による玄米又は無洗米を炊飯した米飯は、食味が良好であり、いわゆる籾臭については気にならない程度であった（図５参照）。 For rice which γ- aminobutyric acid Te Example 3 above smell enriched, it was measured for the content of γ- aminobutyric acid brown rice subjected to hulling (GABA value), the normal brown rice 2.0mg / 100gd. b is 18 mg / 100 gd. for brown rice according to this example . b, 14 mg / 100 gd. of polished rice grains obtained by washing it with no washing It was each content of b, and it was confirmed that the content of γ-aminobutyric acid is increased in this example . Moreover, the cooked rice which cooked the brown rice or the non-washed rice by a present Example had the favorable taste, and was a grade which is not worried about what is called a bad smell (refer FIG. 5).

なお、上記実施例３における加湿温風の通風条件（加湿温風を温度約７０℃で湿度９０％〜９８％、かつ、通風時間（タンク内滞留時間）を少なくとも４時間）については、前記実施例１及び実施例２で述べたように、籾であるが故に胴割れが生じることなく、効率よくγ−アミノ酪酸が富化した籾を大量に生産することができた。 In addition, the ventilation conditions of the humidified warm air in Example 3 (the humidified warm air is about 70 ° C. and the humidity is 90% to 98%, and the ventilation time (retention time in the tank) is at least 4 hours) are as described above. as described in example 1 and example 2, a is but without cylinder cracking occurs because rice efficiently γ- aminobutyric acid was able to produce a large amount of rice enriched.

前記実施例１、実施例２及び実施例３における大規模穀物乾燥調製貯蔵施設（共同乾燥調製施設）１においてγ−アミノ酪酸を富化した大量の籾は穀物貯蔵サイロに備蓄されるものであり、需要に応じて籾摺り・精選等の処理を施して適宜出荷することができるものである。よって、γ−アミノ酪酸を富化したお米をスムーズかつ迅速に市場に供給することができる。また、本発明によるγ−アミノ酪酸が富化した籾は、そのまま家畜等の飼料としても使用することができる。 Example 1, a large amount of rice was turned into wealth γ- aminobutyric acid in Example extensive grain dry preparations storage facilities in 2 and Example 3 (co-dried preparation facility) 1 is intended to be stockpiled grain storage silos Depending on demand, it can be shipped as appropriate after being subjected to processing such as hulling and selection. Therefore, rice enriched with γ-aminobutyric acid can be supplied to the market smoothly and quickly. Moreover, the cocoon enriched with γ-aminobutyric acid according to the present invention can be used as it is as feed for livestock.

本発明における前記実施例１（生籾からギャバ富化）、実施例２（半乾籾からギャバ富化）及び実施例３（仕上げ乾燥籾からギャバ富化）に関しては、実施例２を採用するのがより好ましい。その理由として、実施例２は、荷受籾を一旦半乾燥して貯蔵可能にした後にγ−アミノ酪酸の富化処理をするので、共同乾燥調製施設の荷受工程において荷受待ち等の稼働ロスを最小限にできるほか、米飯品質において比較的籾臭が気にならない故である。 The example of the present invention 1 (raw rice from GABA enrichment), for example 2 (half dry rice from GABA enrichment) and Example 3 (GABA enriched from finishing drying rice), to adopt a second embodiment Is more preferable. The reason is that the second embodiment, after the storable and once semidry the consignee paddy γ- aminobutyric acid Tomikasho sense the to Runode, co dried preparation facility Te consignee step smell of such load受待Chi in addition to possible operating loss to a minimum, relatively rice odor is Iyue such not mind in the cooked rice quality.

なお、本発明は、前記実施例１、実施例２及び実施例３を適宜切換えて実施できるように中央制御部２４において制御するようにすることもできる。これにより、収穫シーズン中の共同乾燥調製施設の荷受ピーク時期の実施形態と、荷受ピーク時期でない時期の実施形態とを任意に切換えて、共同乾燥調製施設の稼働率を維持しつつ効率的にγ−アミノ酪酸が富化したお米を大量生産することが可能である。 The present invention can also be in Example 1, to control the central control unit 24 so as Example 2及 beauty Example 3 can be carried out appropriately switched. As a result, it is possible to arbitrarily switch between the embodiment at the peak receiving period of the joint drying preparation facility during the harvest season and the embodiment at a period other than the peak receiving period, and efficiently γ while maintaining the operating rate of the joint drying preparation facility. -Mass production of rice enriched with aminobutyric acid is possible.

昨今注目されているγ−アミノ酪酸が富化した米を効率的に大量生産し、市場に対して迅速な供給が可能になる。また、昨今のトウモロコシなどの輸入家畜飼料の価格の高騰化を背景に、トウモロコシなどの家畜飼料の一部に代わるものを日本国内において大量生産することができる。 In recent years attention has been and γ- amino butyric acid is efficient mass production of rice enriched, it is possible to quickly supplied to the market. In addition, with the recent increase in the price of imported livestock feed such as corn, a substitute for a part of livestock feed such as corn can be mass-produced in Japan.
