本発明は、米質改良方法に関する。詳しくは、米びつや米倉庫に設置したり、田んぼに埋設したりすることで、米質を改良することのできる米質改良材を用いる米質改良方法に関する。 The present invention relates to a rice quality improving method. For more information, or installed in a flour container and rice warehouse by or embedded in a rice field, to US-improved method Ru uS-improved material that can improve rice quality.
我が国では、古くから、米が主食として広く一般に親しまれ、その品質を如何にして向上させるか、ということは、米の生産・販売を業とするものにとっても、米を食する需要者にとっても、非常に大きな関心事であった。そのため、品種改良や米の栽培方法、精米方法など、様々な観点からの米質改良が試みられてきた。しかし、米質が気候や土壌などの周辺環境に大きく影響を受けるにも関わらず、従来、米質の改良のために、稲の生育環境や米の保存環境など、稲や米の周辺環境を変化させることにより、米質を改良しようとする試みはなされてこなかった。 In Japan, rice has been widely popular as a staple food for a long time, and how to improve the quality of rice is important for both rice production and sales and for consumers who eat rice. It was a very big concern. Therefore, rice quality improvement from various viewpoints such as variety improvement, rice cultivation method, and rice milling method has been tried. However, despite the fact that the quality of rice is greatly affected by the surrounding environment such as climate and soil, in the past, in order to improve the quality of rice, the surrounding environment of rice and rice, such as the growth environment of rice and the preservation environment of rice, has been improved. No attempt has been made to improve the quality of rice by changing it.
そこで、本発明の解決しようとする課題は、稲や米の周辺環境を変化させることで、米質を改良することのできる、米質改良方法を提供することにある。 Therefore, the problem to be solved by the present invention is to provide a rice quality improvement method that can improve the quality of rice by changing the surrounding environment of rice or rice.
本発明者は、上記課題を解決するべく鋭意検討を行った結果、米質改良材として、木炭を用いれば良いことを見出した。木炭によって米質が改良されることについて、詳しいメカニズムは未だ解明できていないが、木炭が有する調湿機能、ガス吸着機能、電磁気的機能などの諸機能、中でも、特に電磁気的機能による何らかの作用が米質に影響を与えることによるものではないかと推察される。さらに、本発明者の検討の結果、このような電磁気的機能を有する木炭には微生物が群がりやすく、この微生物が何らかの作用によって稲や米の周辺環境を改善しているのではないかと考えられた。本発明は、このような知見に基づいて完成されたものである。 As a result of intensive studies to solve the above problems, the present inventor has found that charcoal may be used as the rice quality improving material. Although the detailed mechanism for improving the quality of rice by charcoal has not yet been elucidated, various functions such as humidity control function, gas adsorption function, electromagnetic function, etc. possessed by charcoal, in particular, some action by electromagnetic function. It is presumed that it may be due to affecting the quality of rice. Furthermore, as a result of the study by the present inventor, it is considered that microorganisms tend to gather on charcoal having such an electromagnetic function, and that these microorganisms have improved the surrounding environment of rice and rice by some action. . The present invention has been completed based on such findings.
すなわち、本発明にかかる米質改良方法は、木炭を必須とする米質改良材を、稲の生育環境内に配置する、米質改良方法であって、前記配置が埋設であり、当該埋設が、地面に穿たれた穴の中に、前記米質改良材と水を投入し、さらに、天然塩、水晶、ショールトルマリン、天照石、ブラックシリカ、アパタイトおよび麦飯石からなる群より選ばれる少なくとも１種を投入し、前記穴を埋め戻すことである、ことを特徴とする。
以下では、本発明に用いられる米質改良材または米質改良製品を「本発明にかかる米質改良材」または「本発明にかかる米質改良製品」と言うことがある。
That is, the rice quality improving method according to the present invention is a rice quality improving method in which a rice quality improving material essential to charcoal is placed in the growth environment of rice , wherein the placement is buried, In the hole drilled in the ground, the rice quality improving material and water are added, and at least selected from the group consisting of natural salt, crystal, shawl tourmaline, amaterite, black silica, apatite, and barley stone It is characterized in that one kind is introduced and the hole is backfilled .
Hereinafter, the rice quality improving material or the rice quality improved product used in the present invention may be referred to as “the rice quality improving material according to the present invention” or “the rice quality improved product according to the present invention”.
本発明によれば、稲や米の周辺環境を変化させるという、従来とは異なる手法によって米質の改良を実現することによって、現在流通している米全般の品質について、その水準を一挙に引き上げることができる。 According to the present invention, by improving the quality of rice by a method different from the conventional method of changing rice and the surrounding environment of rice, the level of the quality of all currently distributed rice is raised at once. be able to.
以下、本発明において用いる米質改良材と、本発明の米質改良方法について詳しく説明するが、本発明の範囲はこれらの説明に拘束されることなく、以下の例示以外についても、本発明の趣旨を損なわない範囲で適宜変更実施し得る。
〔米質改良材〕
本発明にかかる米質改良材には、木炭が含まれる。
＜木炭＞
木炭としては、特に限定されず、例えば、活性化木炭、備長炭、竹炭などが挙げられるが、特に活性化木炭を用いると、顕著な米質改良効果が発揮され、好ましい。
Hereinafter, a rice-improved material used Oite the present invention will be described in detail US-improved process of the present invention, the scope of the present invention is not bound to these descriptions, even with the addition to the following examples, the Modifications can be made as appropriate without departing from the spirit of the invention.
[Rice quality improvement material]
The rice quality improving material according to the present invention includes charcoal.
<Charcoal>
The charcoal is not particularly limited, and examples thereof include activated charcoal, Bincho charcoal, bamboo charcoal, and the like. Particularly, when activated charcoal is used, a remarkable effect of improving rice quality is exhibited, which is preferable.
前記活性化木炭は、木材の細片すなわち木材チップを低温炭化させ、次いで、高温炭化させた後、水に接触させて活性化させることにより得ることができる。前記木材チップの原木としては、特に限定されないが、例えば、杉材、ヒマラヤ杉材、赤松材等の針葉樹材が用いられ、特に赤松材が好ましい。木材製品として利用し難く安価な細い木材や廃材を利用することができる。パルプ製造やボード建材の原料として大量に工業生産されている木材チップ製品を用いることもできる。木材チップの形状および寸法は特に限定されないが、木材チップの差し渡し径を測ったときに、その最大径が１０〜６０ｍｍのものが好ましい。大き過ぎる木材チップは十分な炭化を行い難く、小さ過ぎる木材チップは取扱い難く、製造歩留りも悪い。 The activated charcoal can be obtained by low-temperature carbonizing a piece of wood, ie, a wood chip, followed by high-temperature carbonization and then activating by contacting with water. Although the raw wood of the wood chip is not particularly limited, for example, softwood such as cedar, Himalayan cedar and red pine is used, and red pine is particularly preferable. It is possible to use thin wood and waste materials that are difficult to use as wood products and inexpensive. Wood chip products that are industrially produced in large quantities can also be used as raw materials for pulp production and board building materials. The shape and size of the wood chip are not particularly limited, but when the passing diameter of the wood chip is measured, the maximum diameter is preferably 10 to 60 mm. Wood chips that are too large are difficult to carbonize sufficiently, and wood chips that are too small are difficult to handle and have poor production yields.
前記活性化木炭を得るための低温炭化工程および高温炭化工程では、基本的には、通常の木炭製造装置および製造処理条件を採用すればよい。
前記低温炭化工程では、特に限定しないが、例えば、熱処理の温度を４５０〜５５０℃に設定することができる。また、熱処理時間は、木材チップの全体が十分に炭化される程度で良く、木材チップあるいは製造装置の条件によっても異なるが、通常は１００〜１２０時間をかけて処理する。熱処理雰囲気は、空気の流入を遮断した状態で行う。モミ殻やオガクズで木材チップを覆った状態で処理することができる。
前記高温炭化工程では、特に限定しないが、例えば、熱処理の温度を８００〜９００℃、熱処理時間を好ましくは３〜６０分、さらに好ましくは５〜１５分に設定することができる。高温炭化工程では、前工程で低温炭化された木材チップ炭化物の表面に近い一部分のみを高温炭化し、木材チップ炭化物の中心部分には低温炭化部分を残しておく。処理時間によって、得られる活性化木炭に含まれる高温炭化部分と低温炭化部分との比率が調整される。処理時間が短すぎたり長すぎたりすると、高温炭化部分と低温炭化部分とのそれぞれの特性が十分に発揮できない。前記低温炭化工程と同じ装置で、熱処理温度を上昇させることで、低温炭化された木材チップ炭化物をそのまま高温炭化させることが好ましい。熱処理雰囲気は、酸素を供給した状態にする。
In the low-temperature carbonization step and the high-temperature carbonization step for obtaining the activated charcoal, basically, an ordinary charcoal production apparatus and production processing conditions may be employed.
Although it does not specifically limit in the said low temperature carbonization process, For example, the temperature of heat processing can be set to 450-550 degreeC. In addition, the heat treatment time may be such that the whole wood chip is sufficiently carbonized, and it usually takes 100 to 120 hours, although it varies depending on the conditions of the wood chip or the manufacturing apparatus. The heat treatment atmosphere is performed in a state where the inflow of air is blocked. It can be treated with wood chips covered with fir shells and sawdust.
Although it does not specifically limit in the said high temperature carbonization process, For example, the temperature of heat processing can be set to 800-900 degreeC, Preferably heat processing time is 3 to 60 minutes, More preferably, it can be set to 5 to 15 minutes. In the high-temperature carbonization step, only a portion near the surface of the wood chip carbide that has been low-temperature carbonized in the previous step is high-temperature carbonized, and the low-temperature carbonization portion is left in the central portion of the wood chip carbide. The ratio of the high temperature carbonization part and the low temperature carbonization part contained in the activated charcoal obtained is adjusted by processing time. If the treatment time is too short or too long, the respective characteristics of the high temperature carbonized portion and the low temperature carbonized portion cannot be sufficiently exhibited. It is preferable that the wood chip carbide that has been carbonized at low temperature is carbonized as it is by increasing the heat treatment temperature in the same apparatus as the low-temperature carbonization step. The heat treatment atmosphere is in a state where oxygen is supplied.
高温炭化工程で熱処理を行った炭化物に水を接触させると、炭化物は急速に冷却されて消火する。その際に、水の化学的および物理的な作用によって、炭化物に複雑な形状の微細孔が形成されたり、炭化物の表面が改質されて吸着能などが向上したりする活性化が行われる。なお、水は液体状態であってもよいが、通常は水蒸気状態で炭化物に接触することになる。活性化工程の具体的処理装置や処理条件は、既知の活性炭製造技術において行われている水との接触処理と同様でよい。
このようにして得られる活性化木炭は、内部に多数の微細孔を有する多孔質構造であり、この微細孔による物理的な吸着作用を有するとともに、微細孔の表面が化学的あるいは物理的に活性化されていて高い吸着能を発揮する。前記製造方法から判るように、活性化木炭は、原料となる木材チップ以外の添加剤や活性化処理剤を使用する必要がない。
When water is brought into contact with the carbide that has been heat-treated in the high-temperature carbonization process, the carbide is rapidly cooled and extinguished. At that time, activation is performed by chemical and physical action of water such that fine pores having a complicated shape are formed in the carbide, or the surface of the carbide is modified to improve the adsorption ability. Although water may be in a liquid state, it usually comes into contact with the carbide in a water vapor state. The specific treatment apparatus and treatment conditions of the activation step may be the same as the contact treatment with water that is performed in a known activated carbon production technique.
The activated charcoal obtained in this way has a porous structure with a large number of micropores inside, and has a physical adsorption action by the micropores, and the surface of the micropores is chemically or physically active. It has a high adsorption capacity. As can be seen from the above production method, activated charcoal does not require the use of additives or activation treatment agents other than wood chips as raw materials.
活性化木炭は、吸着能に優れ、吸放湿性、脱臭性、防黴性、遠赤外線放射性、導電性、電磁波吸収性、イオン調整機能などに優れている。活性化木炭の吸着能は、吸着物質と接触したときの立ち上がり速度が大きい。また、吸着物質を分解する作用があるため、活性化木炭の微細孔に吸着物質が詰まって吸着能が低下することが防げ、長期間にわたって安定した吸着能を発揮できる。
活性化木炭には、低温炭化工程で炭化された低温炭化部分と、高温炭化工程でさらに炭化された高温炭化部分とが混在している。通常は、中心側に低温炭化部分、外周側に高温炭化部分が存在する。活性化木炭は、低温炭化部分と高温炭化部分の機能や役目を相乗的に発揮させることができる。
Activated charcoal is excellent in adsorptive capacity, and is excellent in moisture absorption / desorption, deodorization, mildew resistance, far-infrared radiation, conductivity, electromagnetic wave absorption, ion adjustment function, and the like. The activated charcoal adsorbing ability has a large rising speed when it comes into contact with the adsorbing substance. Moreover, since it has the effect | action which decomposes | disassembles an adsorbent substance, it can prevent that an adsorbent substance clogs into the micropore of activated charcoal, and adsorbability falls, and can exhibit stable adsorbability over a long period of time.
The activated charcoal contains a mixture of a low temperature carbonized portion carbonized in the low temperature carbonization step and a high temperature carbonized portion further carbonized in the high temperature carbonization step. Usually, there is a low-temperature carbonized portion on the center side and a high-temperature carbonized portion on the outer peripheral side. The activated charcoal can synergistically exhibit the functions and roles of the low temperature carbonized portion and the high temperature carbonized portion.
前記活性化木炭は、粉砕して活性化木炭粉にすることで、他の材料に対する担持や含有の処理が行い易くなる。
粉砕装置および粉砕条件は、通常の木炭粉の製造技術が適用できる。
活性化木炭粉を粒径５ｍｍ以下に粉砕するのが好ましい。粒径が小さいほど、単位重量当たりの表面積が大きくなり、表面性状に基づく諸特性が向上する。
前記したように低温炭化部分と高温炭化部分とが混在する活性化木炭を粉砕した活性化木炭粉にも、低温炭化部分と高温炭化部分とが混在する。個々の活性化木炭に低温炭化部分と高温炭化部分が存在することが好ましいが、低温炭化部分からなる活性化木炭粉と高温炭化部分からなる活性化木炭粉とが均一に分散していてもよい。
By pulverizing the activated charcoal into activated charcoal powder, it becomes easy to carry or support other materials.
As the pulverizing apparatus and pulverizing conditions, a normal charcoal powder manufacturing technique can be applied.
The activated charcoal powder is preferably pulverized to a particle size of 5 mm or less. The smaller the particle size, the larger the surface area per unit weight and the various properties based on the surface properties are improved.
As described above, the activated charcoal powder obtained by pulverizing the activated charcoal in which the low-temperature carbonized portion and the high-temperature carbonized portion coexist also contains the low-temperature carbonized portion and the high-temperature carbonized portion. It is preferable that each activated charcoal has a low-temperature carbonized portion and a high-temperature carbonized portion, but the activated charcoal powder composed of the low-temperature carbonized portion and the activated charcoal powder composed of the high-temperature carbonized portion may be uniformly dispersed. .
本発明で用いる前記木炭は、予め帯電させたものであることが好ましい。予め帯電しておくことにより、米質改良効果も向上する。これは、帯電により、木炭の電磁気的作用が向上し、さらに、木炭に微生物が群がりやすくなり、微生物による作用が向上することによるものと考えられる。
前記木炭の帯電方法としては、特に限定するわけではないが、例えば、電圧をかけて静電場を作り、この静電場の中に木炭を置いた状態で１昼夜放置する、という方法が挙げられる。このとき、木炭は、該木炭中の電荷が外部へ伝導しないように、絶縁状態の架台の上に置いておく。高電圧をかけることが好ましく、限定するわけではないが、例えば、５０〜１５０Ｖとすることができる。
The charcoal used in the present invention is preferably charged in advance. By charging in advance, the rice quality improvement effect is also improved. This is considered to be due to the fact that the electromagnetic action of charcoal is improved by charging, and that microorganisms easily gather on the charcoal, thereby improving the action of the microorganism.
The method for charging the charcoal is not particularly limited. For example, there is a method in which an electrostatic field is generated by applying a voltage, and the charcoal is left in the electrostatic field for one day. At this time, the charcoal is placed on an insulated base so that the electric charge in the charcoal is not conducted to the outside. Although it is preferable to apply a high voltage and it is not necessarily limited, it can be set to 50-150V, for example.
