Description

【００１４】
表１にみられるように、食用油にｄ−リモネンを溶解させることによって排出時間を１／３〜１／７程度に短縮することができ、食用油の粘性を１／３〜１／７程度に低下させることができるものであり、また食用油にα−ピネンを溶解させることによって排出時間を１／２〜１／３程度に短縮することができ、食用油の粘性を１／２〜１／３程度に低下させることができるものであった。このように食用油にリモネンやピネンを溶解させることによって食用油の粘性を大きく低下させることができることが確認されるが、粘性を低下させる作用はリモネンのほうが大きく、リモネンを用いることがより好ましい。また、樟脳も食用油に溶解させることができるが、樟脳を食用油に溶解しても食用油の粘性に殆ど影響を与えるものではなかった。
【００１５】
次に、ｄ−リモネンやα−ピネンの溶解量と食用油の粘性の関係をみるために、サラダ油に対してｄ−リモネンやα−ピネンを１０質量％、２０質量％、３０質量％溶解し、上記と同様にして排出時間の測定を行なった。結果を表２に示す。
【００１６】
【表２】

【００１７】
表２にみられるように、リモネンやピネンの溶解量の増加と共に食用油の粘性が低下することが確認される。
【００１８】
上記のように食用油にリモネンやピネンを混合・溶解して得られる悪臭防止用コーティング剤は、リモネンあるいはピネンの溶解によって粘性が小さくなっており、噴霧機を用いて霧状に噴霧することが可能になる。従って糞肥料等の有機質肥料など、粒状の悪臭物質にこの悪臭防止用コーティング剤を噴霧して、悪臭物質の表面に付着させた状態で攪拌混合することによって、悪臭物質の粒の表面に均一にコーティングすることができるものである。
【００１９】
食用油に対するリモネンやピネンの混合量は、特に限定されるものではないが、食用油に対して２０〜３５質量％の範囲が好ましい。リモネンやピネンの混合量が２０質量％未満であると、食用油の粘性を低下させる効果が不十分である。リモネンやピネンの混合量が３５質量％を超える場合、相対的に食用油の量が減少するので食用油のコーティング膜の形成による悪臭防止の効果が低下するおそれがあり、またリモネンやピネンは揮発性物質であるので長期保存性に問題が生じると共に、コストの面でも問題が生じるものである。そして悪臭物質に対する本発明に係る悪臭防止用コーティング剤のコーティング量は、１．０〜２．５質量％の範囲が好ましい。悪臭防止用コーティング剤のコーティング量が１．０質量％未満であると、コーティングが不十分になって悪臭の放散を十分に防ぐことが難しい。逆に悪臭防止用コーティング剤のコーティング量が２．５質量％を超えても、悪臭防止の効果はそれ以上あまり増大しないので、コスト的に不利になるおそれがある。
【００２０】
ここで、本発明に係る悪臭防止用コーティング剤は上記のように粘性が低く、悪臭物質に噴霧して混合することができるため、悪臭物質の粒の表面に凹凸があっても、凹の部分にまで悪臭防止用コーティング剤を付着させてコーティングすることができるものであり、また悪臭物質に対して３質量％を超えて混合しても、悪臭防止用コーティング剤は粘性が低いため、有機質肥料の粒同士が接着して大きな塊になったり、攪拌機に付着したりするようなことがなくなるものである。
【００２１】
そしてこのように被処理材の表面に食用油からなる悪臭防止用コーティング剤を均一にコーティングすることができるために、悪臭物質の表面を均一に食用油の膜で被覆することができ、悪臭物質の臭気をこの食用油の膜でマスキングして閉じ込め、悪臭物質から臭気が放散されることを防ぐことができるものである。また悪臭防止用コーティング剤に含有されるリモネンやピネンは、わずかではあるが香気を出すので、この香気によっても悪臭物質の臭気を打ち消して、臭気の放散を防ぐことができるものである。
【００２２】
悪臭の放散は一般に温度に関係し、冬場など低温であれば悪臭の発生量が少なく、この場合には、上記のような食用油とリモネンやピネンを混合して調製した悪臭防止用コーティング剤で悪臭の発生を十分に防ぐことができる。しかし、夏場など高温時には有機質肥料などの悪臭物質に含有されている水分が蒸発する際に、悪臭防止用コーティング剤によるコーティング皮膜が剥がれて悪臭が放出されるおそれがある。
【００２３】
そこでこのときには、リモネンとピネンの少なくとも一方に芳香油、樟脳、メントウルから選ばれる芳香成分を添加して溶解した状態で、食用油に混合することによって調製される悪臭防止用コーティング剤を用いるようにしている。芳香油、樟脳、メントウルはいずれも芳香を強く発生する物質であり、食用油にリモネンやピネンの他にこれらの芳香成分を含有させて悪臭防止用コーティング剤を調製することによって、有機質肥料などの悪臭物質にコーティングした皮膜が剥がれても、悪臭を芳香成分の芳香によって打ち消すことができ、悪臭が広がることを防ぐことができるものである。
【００２４】
芳香油（アロマオイル）としてはラベンダー、グレープフルーツ、ジャスミン、ペパーミント、スイートオレンジ、ローズ、レモングラス、ローズマリー、レモン、ジャーマン・カモミールなどの植物から抽出された精油を用いることができ、これらのうち一種を用いる他、二種以上を併用することもできる。また芳香油、樟脳、メントウルは、これらのなかから一種を用いる他、二種以上を併用することもできる。これらはそれぞれ、芳香油は微量でも悪臭を打ち消す効果がある、樟脳は酸化還元の影響を受けず、長期間悪臭を打ち消す効果を持続させることができる、メントウルは短期間で匂いが消失するが、香料的匂いではなく一般に好まれる淡い匂いである、という特徴を有するので、これらの特徴を活かすように組み合わせて用いるのが望ましい。
【００２５】
食用油に芳香油、樟脳、メントウルを直接添加して混合することも可能であるが、芳香油、樟脳、メントウルはリモネンやピネンに良好に溶解するので、リモネンやピネンに芳香油、樟脳、メントウルを添加して溶解した状態で、食用油に混合することによって、食用油に芳香油、樟脳、メントウルを均一に分散させることができるものである。ちなみに、リモネンに対する樟脳の溶解度は２５質量％程度、ピネンに対する樟脳の溶解度は２７質量％程度であり、良好に溶解させることができるものである。
【００２６】
リモネンやピネンに対する芳香油、樟脳、メントウルから選ばれる芳香成分の配合量は、特に限定されるものではないが、１０〜４０質量％の範囲が好ましく、１５〜３５質量％の範囲がより好ましい。芳香成分の配合量が１０質量％未満では、芳香による悪臭を消臭する効果を十分に得ることが難しく、４０質量％を超えると、芳香成分からの芳香が強くなり過ぎて、却って逆効果になるおそれがある。
【００２７】
ここで、本発明に係る悪臭防止用コーティング剤の材料である、食用油、リモネン、ピネン、芳香油、樟脳、メントウルはいずれも、毒性を有しない安全物質であるので、悪臭防止用コーティング剤を安全に使用することができ、またこの悪臭防止用コーティング剤で肥料の表面をコーティングしても、肥効に悪影響を及ぼすことはない。
【００２８】
尚、本発明に係る悪臭防止用コーティング剤は、上記のような糞肥料などの有機質肥料の悪臭防止用に用いる他、悪臭を発する任意の物の表面にコーティングして悪臭を防止することができるものである。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a coating agent for preventing malodor used by coating malodorous substances such as fertilizer.
[0002]
[Prior art]
It is well known that the application of organic fertilizers to produce high quality crops is effective. In particular, animal dung has a high active ingredient content, and the composition is well balanced between fast-acting, slow-acting, and slow-acting substances.Moreover, it increases soil microorganisms, promotes soil agglomeration, and suppresses continuous cropping failure. Therefore, fecal fertilizers made from feces, such as fermented dry feces fertilizer and poultry feces fertilizer, have been widely used. However, organic fertilizers such as dung fertilizers have a bad smell, particularly dung fertilizers made from poultry dung have a strong smell, and tend to avoid dung fertilizers in farms and home gardens near private houses.
[0003]
Therefore, attempts have been made to mix edible oil or molasses with organic fertilizer and coat the surface of the grains of the organic fertilizer with a film of edible oil or molasses. By coating the surface of the organic fertilizer grains with edible oil or molasses in this way, the surface of the organic fertilizer is covered with a film of edible oil or molasses, and the odor of the organic fertilizer is reduced by the edible oil or molasses film. It is possible to prevent the odor from being emitted from the organic fertilizer by masking and confining the organic fertilizer.
[0004]
[Problems to be solved by the invention]
However, since edible oil and molasses are highly viscous, it is difficult to spray and mix them, and it is difficult to spray and coat a small amount of edible oil or molasses of 1 to 2% by mass on organic fertilizer. It was extremely difficult. For this reason, edible oil and molasses are stirred with organic fertilizer using an amount of 2% by mass or more, but highly viscous edible oil or molasses is added to the surface of the particles having irregularities of the organic fertilizer. It is difficult to coat uniformly, and there is a problem that the coating of the concave portion is incomplete, odor is radiated from this portion, and the effect of preventing malodor is insufficient. In addition, highly viscous edible oils and molasses adhere to the stirrer, making it difficult to stir, and furthermore, the viscosity of the edible oils and molasses causes the organic fertilizer grains to aggregate, resulting in large lumps and poor fluidity, This caused problems in the workability of weighing and bagging.
[0005]
The present invention has been made in view of the above points, and makes it possible to uniformly and easily coat the surface of an odorous substance such as an organic fertilizer, and has a high effect of preventing the emission of offensive odors. It is intended to provide an agent.
[0006]
[Means for Solving the Problems]
The odor preventing coating agent according to claim 1 of the present invention is characterized by comprising at least one of limonene and pinene mixed in edible oil.
[0007]
A second aspect of the present invention is characterized in that, in the first aspect, at least one of aromatic oil, camphor and menthol is dissolved in at least one of limonene and pinene for use.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described.
[0009]
In the present invention, vegetable oils such as salad oil and tempura oil are preferably used as the edible oil, and these waste oils can also be used. Salad oil is made of cottonseed oil, corn oil, rapeseed oil, rice oil, etc.Tempura oil is made of soybean oil, rapeseed oil, rice oil, etc., each of which is commercially available from an edible oil manufacturer. Can be used. Waste oil is oil discarded after using these edible oils as frying oil and the like, and it is desirable to use the waste oil mixed with edible oil.
[0010]
By mixing at least one of limonene and pinene with this edible oil, the odor preventing coating agent according to the present invention can be obtained. Limonene is a monoterpene hydrocarbon, a colorless liquid with a lemon-like scent, and used as a raw material for fragrance. This limonene has an optical isomer and d-limonene is preferred, but l- and dl- can also be used. Also, pinene is one of monoterpene hydrocarbons, a colorless liquid having a characteristic wood-like fragrance, and is used as a raw material for perfume. This pinene includes α- and β-, and any of them can be used.
[0011]
The present invention has been made based on the novel finding that vegetable edible oil and limonene and pinene dissolve each other. That is, it can be dissolved by mixing limonene and pinene with the edible oil, and a malodor preventing coating agent in which the viscosity of the edible oil is reduced by dissolving limonene and pinene can be obtained. One of limonene and pinene may be used alone, or both may be used in combination.
[0012]
Here, the test results of the viscosity of the edible oil are shown. The viscosity was measured by using a 30 cc capacity syringe having an injection port with an inner diameter of 1 mm, placing 10 cc of the sample solution into the syringe with the injection port facing down, and placing the sample liquid in a 25 ° C. room temperature atmosphere. This was done by measuring the time required to drain from The discharge time was measured for edible oils such as salad oil, its waste oil and rice oil, and for each of these edible oils in which 30% by mass of d-limonene or α-pinene was mixed and dissolved (in addition to this). , Mass% is an inner line, for example, dissolving 30% by mass of d-limonene in salad oil means dissolving 30 parts by mass of d-limonene in 70 parts by mass of salad oil. Is.). For reference, d-limonene, α-pinene and tap water were also measured. Further, camphor is mixed and dissolved in each of the above edible oils with 8.7% by mass for salad oil, 7.5% by mass for waste oil, and 3.4% by mass for rice oil. Was measured in the same manner. Table 1 shows the results.
[0013]
[Table 1]

[0014]
As can be seen in Table 1, by dissolving d-limonene in edible oil, the discharge time can be reduced to about 1/3 to 1/7, and the viscosity of the edible oil can be reduced to about 1/3 to 1/7. By dissolving α-pinene in the edible oil, the discharge time can be reduced to about １ ／ to 、, and the viscosity of the edible oil can be reduced to １ to １. / 3). It is confirmed that the dissolution of limonene and pinene in the edible oil can greatly reduce the viscosity of the edible oil, but the effect of lowering the viscosity is greater for limonene, and it is more preferable to use limonene. Also, camphor can be dissolved in edible oil, but dissolving camphor in edible oil hardly affected the viscosity of edible oil.
[0015]
Next, in order to examine the relationship between the amount of d-limonene and α-pinene dissolved and the viscosity of the edible oil, 10%, 20% and 30% by mass of d-limonene and α-pinene were dissolved in salad oil. The discharge time was measured in the same manner as described above. Table 2 shows the results.
[0016]
[Table 2]

[0017]
As shown in Table 2, it is confirmed that the viscosity of the edible oil decreases as the amount of limonene or pinene dissolved increases.
[0018]
The odor prevention coating agent obtained by mixing and dissolving limonene and pinene in edible oil as described above has reduced viscosity due to dissolution of limonene or pinene, and can be sprayed in a mist state using a sprayer. Will be possible. Therefore, the coating agent for preventing malodor is sprayed on granular malodorous substances such as organic fertilizers such as manure fertilizers, and is stirred and mixed in a state of being attached to the surface of the malodorous substances, so that the surface of the malodorous substance particles is uniformly mixed. It can be coated.
[0019]
The amount of limonene or pinene mixed with the edible oil is not particularly limited, but is preferably in the range of 20 to 35% by mass based on the edible oil. When the amount of limonene or pinene is less than 20% by mass, the effect of lowering the viscosity of the edible oil is insufficient. If the amount of limonene or pinene exceeds 35% by mass, the amount of edible oil is relatively reduced, so that the effect of preventing odors due to the formation of a coating film of edible oil may be reduced, and limonene and pinene are volatile. Since it is an acidic substance, it causes a problem in long-term storage properties and also causes a problem in cost. The coating amount of the offensive odor preventing coating agent according to the present invention with respect to the offensive odor substance is preferably in the range of 1.0 to 2.5% by mass. If the coating amount of the odor preventing coating agent is less than 1.0% by mass, the coating becomes insufficient and it is difficult to sufficiently prevent the emission of odor. Conversely, if the coating amount of the odor preventing coating agent exceeds 2.5% by mass, the effect of preventing odor does not increase so much, so that there is a possibility that the cost may be disadvantageous.
[0020]
Here, the odor preventing coating agent according to the present invention has a low viscosity as described above, and can be mixed by spraying on the odorous substance. It can be coated by applying an odor-preventing coating agent up to, and even if it is mixed in more than 3% by mass with respect to the odorous substance, the odor-preventing coating agent has a low viscosity. Are prevented from adhering to each other to form a large lump or to adhere to a stirrer.
[0021]
Further, since the surface of the material to be treated can be uniformly coated with the odor preventing coating agent composed of edible oil, the surface of the odorous substance can be uniformly coated with the edible oil film. The odor of the edible oil is masked and confined by the edible oil film to prevent the odor from being released from the malodorous substance. Further, limonene and pinene contained in the malodor preventing coating agent emit a small amount of odor, so that the odor can also counteract the odor of the malodorous substance and prevent the odor from being emitted.
[0022]
The emission of offensive odors is generally related to the temperature, and the amount of odors generated is low at low temperatures such as in winter.In this case, the odor prevention coating agent prepared by mixing the above-mentioned edible oil with limonene or pinene is used. The generation of offensive odor can be sufficiently prevented. However, at high temperatures such as in summer, when the moisture contained in the malodorous substances such as organic fertilizers evaporates, the coating film formed by the malodor preventing coating agent may be peeled off and the malodor may be released.
[0023]
Therefore, at this time, a odor-preventing coating agent prepared by adding an aromatic component selected from aromatic oil, camphor and menthol to at least one of limonene and pinene and dissolving it in the cooking oil is used. ing. Aromatic oil, camphor, and menthol are all substances that strongly generate fragrance.By adding these fragrance components to edible oil in addition to limonene and pinene to prepare a coating agent for preventing odors, such as organic fertilizers Even if the film coated on the offensive odor substance is peeled off, the offensive odor can be counteracted by the fragrance of the fragrance component and the odor can be prevented from spreading.
[0024]
As the aromatic oil (aroma oil), essential oils extracted from plants such as lavender, grapefruit, jasmine, peppermint, sweet orange, rose, lemongrass, rosemary, lemon, german chamomile can be used. Or two or more of them can be used in combination. Aromatic oil, camphor, and menthol can be used alone or in combination of two or more. In each of these, aromatic oils have the effect of counteracting odors even in trace amounts, camphor is not affected by redox, can maintain the effect of counteracting odors for a long time, menthol disappears in a short period of time, Since it has a characteristic that it is a generally preferred pale odor instead of a perfume-like odor, it is desirable to use them in combination to take advantage of these characteristics.
[0025]
It is also possible to directly add and mix aromatic oil, camphor and menthol to edible oil, but since aromatic oil, camphor and menthol dissolve well in limonene and pinene, aromatic oil, camphor and menthol are added to limonene and pinene. The aromatic oil, camphor, and menthol can be uniformly dispersed in the edible oil by mixing the edible oil with the edible oil in a dissolved state. Incidentally, the solubility of camphor in limonene is about 25% by mass, and the solubility of camphor in pinene is about 27% by mass, which can be dissolved well.
[0026]
The amount of the aromatic component selected from the aromatic oil, camphor and menthol relative to limonene and pinene is not particularly limited, but is preferably in the range of 10 to 40% by mass, and more preferably in the range of 15 to 35% by mass. If the blending amount of the fragrance component is less than 10% by mass, it is difficult to sufficiently obtain the effect of deodorizing the odor caused by the fragrance, and if it exceeds 40% by mass, the fragrance from the fragrance component becomes too strong, and on the contrary, it has the opposite effect. Could be.
[0027]
Here, the material of the coating agent for preventing malodor according to the present invention, edible oil, limonene, pinene, aromatic oil, camphor and menthol are all non-toxic safety substances. It can be used safely, and coating the surface of fertilizers with this odor-preventing coating agent does not adversely affect the fertilizer effect.
[0028]
The coating agent for preventing malodor according to the present invention can be used to prevent malodor of organic fertilizers such as fecal fertilizers as described above, and can be coated on the surface of any object that emits malodor to prevent malodor. Things.
[0029]
【Example】
Next, the present invention will be described specifically with reference to examples.
[0030]
(Example 1)
0.3 liters of d-limonene was added to a total of 1 liter of edible oil of 0.7 liter of salad oil (manufactured by Linol Oil & Fat Co., Ltd.) and 0.3 liter of the waste oil, and the mixture was stirred and mixed to give a bad odor. A coating for prevention was prepared.
[0031]
Also, quail manure prepared by mixing and fermenting quail carcasses, quail eggshell, and quail excrement was used as organic fertilizer. This quail dung fertilizer has a strong peculiar odor. Then, 100 kg of the organic fertilizer was sprayed with the entire amount of the above-mentioned coating agent for preventing odor, and the mixture was mixed with a stirrer, so that the surface of the organic fertilizer was coated with the coating agent for preventing odor.
[0032]
(Example 2)
