【００４４】
次に、本発明の上述した最適混合比の動物用糞尿処理材の実験結果について詳細に説明する。
【００４５】
(A)米ぬか1.5kg（30％）、脱脂米ぬか1.9kg（38％）、コーンスターチ0.5kg（10％）、炭酸カルシウム0.5kg（10％）、乾燥おから0.6kg（12％）、クエン酸25gをミキサーで2分間混合攪拌し、この混合物に食用色素の青色１号1.5gと黄色４号1gを水150ccで溶かした水溶液を添加し、更に5分間混合攪拌した後、この混合物を造粒機のホッパーに投入し、200kg／時間の吐出速度で先端ダイスから吐出させ、直径3.5mm、長さ4〜7mmの黄緑色に着色された無定形片多孔質粒の動物用糞尿処理材を約5kg得た。これを80℃に設定された温風流動乾燥機内で製品として最も安定化する含水率7.5％の処理材に調整した。試験を繰り返して得た本発明の動物用糞尿処理材の含水率は、好適には6〜9％、より好適には7〜8％、最適には7.5％である。また、黄緑色に着色した動物用糞尿処理材を猫に試験使用した結果、無着色との使用状況に差異がなく、糞尿の吸収後も色素は安定し、色素の流出が起こらなかった。
【００４６】
(B)上述(A)で得た動物用糞尿処理材の消臭力を下記の要領で検査した。ガラス製三角フラスコ（容量約3.36L）に動物用糞尿処理材50gを投入し、アンモニア水（濃度0.01％）を20mL添加、密栓し、１時間放置した後、フラスコ内の空気中のアンモニア濃度を測定した。結果、アンモニア濃度は、動物用糞尿処理材非投入の場合の53.3ppmに対し、0.8ppmであり、アンモニア臭はほとんど確認できなかった。

以上、本発明の実施の形態を詳述したが、本発明の具体的な構成はこの実施の形態に限られるものではなく、本発明の要旨を逸脱しない範囲の変更等があっても本発明に含まれる。例えば、本発明の動物用糞尿処理材は、米ぬかと脱脂米ぬかを含有するもの、米ぬかと脱脂米ぬかと植物性接着剤を含有するもの、米ぬかと脱脂米ぬかと植物性接着剤と乾燥おからを含有するもの、米ぬかと脱脂米ぬかと植物性接着剤と乾燥おからと無機充填剤を含有するもののいずれでも良い。
【００５０】
（第２実施形態）
本発明者は、安価でなおかつ消臭効果が期待できる米ぬかを、動物用糞尿処理材に、あくまでも添加剤としてではなく、原料として使用できるか否かを研究してきた。しかし、米ぬかは、油分を含むため米ぬかを造粒しても、また他の鉱物・紙粉・木粉・おからと混合して造粒しても、水分をはじくため、尿吸収力を阻害してしまい動物用糞尿処理材の原料としてそのままでは使用できなかった。
【００５１】
本発明者は、米ぬかから米油を搾油する油脂工場の副産物である、脱脂米ぬかに着目した。搾油後の副産物である脱脂米ぬかは、油脂分を取り除いてあるため、米ぬかでは得られなかった尿を吸収する性能があり、動物用糞尿処理材の原料として十分使用に値する材料であり、強力な消臭力を有することを発見した。即ち、本発明は、初めて最適な消臭材としての脱脂米ぬかを動物用糞尿処理材の原料として配合し、画期的に消臭度を高めた動物用糞尿処理材を製造するものである。
【００５２】
本発明の動物用糞尿処理材は、脱脂米ぬかを主成分とする。本発明の動物用糞尿処理材は、脱脂米ぬか単独から成るものの他、脱脂米ぬかに木粉、紙粉、鉱物又はおから等を添加し、更に所望により高分子吸収体、着色剤、脱臭剤も添加した混合物を、多孔質粒に造粒して使用に供することができる。
【００５３】
本発明の動物用糞尿処理剤は以下の如くに製造される。
(1)脱脂米ぬかに、所望の木粉、紙粉、鉱物又はおから、更に所望の高分子吸収体、脱臭剤を添加し、常温にてミキサーで攪拌し、更に着色剤の溶液を添加して攪拌する。
【００５４】
(2)上述(1)で得られる混合物を造粒機のダイスに圧入して加圧、造粒し、無数の孔（独立孔、連続孔等の隙間）を有する多孔質粒を成形する。
【００５５】
上述(1)の混合物の攪拌時には少量の水分を添加する。水分は着色剤の水溶液の形態で添加することができる。
【００５６】
上述(1)の混合物の攪拌時に添加する水分量の調整、上述(2)の造粒機のダイスの形状、加圧力の調整により、多孔質粒の孔の大きさ、孔の分布密度を調整できる。小加圧力で粒の尿吸収吸着量を多くし、大加圧力で粒の機械的強度を高めることができる。
【００５７】
本発明の動物用糞尿処理材は以下の作用を有する。
（請求項６に対応する作用）
▲１▼脱脂米ぬかは米油を絞った後の残渣であって原料コストが安価であり、これらを主成分とする動物用糞尿処理材のコストを低減できる。
【００５８】
▲２▼脱脂米ぬかは植物性であり、糞尿吸収後の焼却、生分解、水洗トイレでの水洗処理性等の廃棄処理性が良い。
▲３▼脱脂米ぬかは強力な消臭性により、糞尿に対する高い消臭度を呈する。
【００５９】
以下、本発明の脱脂米ぬかを含有する動物用糞尿処理剤の消臭力の検証結果について説明する（表４〜表８）。

【表８】

【００６５】
(A)表４〜表８の動物用糞尿処理剤の各成分（木粉と脱脂米ぬかと高分子吸収体、紙粉と脱脂米ぬかと高分子吸収体、ベントナイトと脱脂米ぬか、乾燥おからと脱脂米ぬかとコーンスターチ、脱脂米ぬかとコーンスターチ）の原料合計2kgを3分間ミキサーで攪拌した後、その混合物を定量供給機から、50kg/時間の圧縮型造粒機に投入しダイス径から押し出し、長さ4mm〜7mmにカットし乾燥機にかけ水分7.5％の円柱ペレット状の多孔質粒の動物用糞尿処理材を得た。
【００６６】
(B)上述(A)で得た動物用糞尿処理材の消臭度を下記の要領で測定した。ガラス製三角フラスコ（容量3.36L）に動物用糞尿処理材50gを投入し、アンモニア水（0.01%）を20ml添加、密栓し、1時間放置した後、フラスコ内のアンモニア濃度を測定した。
【００６７】
表４の例１の場合、木粉90％・高分子吸収体（接着剤）10％・脱脂米ぬか０で、アンモニア濃度15.2ppm、表４の例５の場合、木粉50％・高分子吸収体（接着剤）10％・脱脂米ぬか40%の配合で、アンモニア濃度1.8ppmまで下がり、驚くべき消臭力があることを確認できた。
【００６８】
以下、表４〜表７の例１〜２０のアンモニア濃度の数値が示すとおり、脱脂米ぬかの含有により消臭力が例外なく増すことが、検証できた。
【００６９】
表８の例２１の脱脂米ぬか90%とコーンスターチ10%の場合は、造粒されたペレットがかたくて表面に光沢を帯びてしまい、ペレット内に臭気を取り込めないため、消臭度が下がらないものと思われる。
【００７０】
脱脂米ぬかを動物用糞尿処理材の原料として使用するためには、単独でなく他の原料と配合し多孔質の粒状に仕上げることが望ましい。
【００７１】

[0004]
[Problems to be solved by the invention]
Paper-based animal excrement disposal materials for animals have a low degree of deodorization of absorbed manure.
The dried okara-based animal manure processing material is not only expensive but also requires further improvement in the deodorization degree of manure.
[0005]
Although conventional animal manure treatment materials have been added with deodorants and deodorizers composed of chemical and plant components in search of a high deodorization level, they do not have a satisfactory deodorization level. It is expensive, and an effect cannot be expected with a small addition amount, and it is not a matter of adding a large amount in search of a high effect, and an appropriate deodorant cannot be found.

[0015]
DETAILED DESCRIPTION OF THE INVENTION
(First embodiment)
The animal manure treatment material of the present invention comprises a rice bran and defatted rice bran as main components, a vegetable adhesive, an inorganic filler and dried okara added, and a mixture containing a colorant and a deodorant as desired. It is granulated into granules.
[0016]
As the plant adhesive, starches and agricultural products containing starch can be used. As starches, corn starch, sweet potato starch, potato starch, tapioca starch and the like can be used. As the agricultural product containing starch, corn, rice, wheat, wheat, root vegetables and the like can be used.
[0017]
As the inorganic filler, calcium carbonate, zeolite, talc and the like can be used.
[0018]
Food coloring can be used as the colorant.
As the deodorizer, citric acid or the like can be used.
[0019]
The animal manure treating agent of the present invention is produced as follows.
(1) Stir rice bran and defatted rice bran with vegetable adhesive, inorganic filler, dried okara, deodorizer at room temperature with a mixer, and then add colorant solution and stir.
[0020]
(2) The mixture obtained in the above (1) is press-fitted into a granulator die, pressed and granulated to form porous particles having innumerable pores (individual pores, gaps such as continuous pores).
[0021]
A small amount of water is added during the stirring of the above mixture (1). Moisture can be added in the form of an aqueous solution of a colorant. The amount of water added is adjusted according to the variation in raw materials purchased, seasonal factors, etc., and at the standard time, it is suitable for the total weight of rice bran, defatted rice bran, vegetable adhesive, inorganic filler, and dried okara 2 to 4%, more preferably 2.5 to 3.5%, and most preferably 3%.
[0022]
By adjusting the amount of water added during the stirring of the mixture of (1) above, the shape of the die of the granulator of (2) above, and adjusting the pressing force, the pore size and pore distribution density of the porous particles can be adjusted. . The small amount of urine absorption / absorption can be increased with a small pressure, and the mechanical strength of the particle can be increased with a large pressure.
[0023]
The animal excrement disposal material of the present invention has the following actions.
(Operation corresponding to claim 1)
(1) Rice bran is a by-product of rice milling, and defatted rice bran is a residue after squeezing rice oil, and the raw material costs are both low (rice bran is cheaper than defatted rice bran), and these are the main ingredients. The cost of animal excrement disposal materials can be reduced.
[0024]
{Circle around (2)} Rice bran and defatted rice bran are plant-based and have good disposal properties such as incineration, biodegradation after sewage absorption, and water washability in flush toilets.
[0025]
(3) Although rice bran has an excellent deodorizing property, it has low water absorption by itself, is non-coagulable, hardly absorbs manure, and has a low agglomeration degree after absorbing manure. Although defatted rice bran has excellent deodorizing properties, high absorbency, and solidification, it is a fine powder with a smooth surface and is difficult to be made porous when granulated. Since it is difficult to form, it cannot be expected to absorb a large amount of urine quickly and to adsorb the urine on the wall of the hole by introducing the urine into the holes. On the other hand, when rice bran and defatted rice bran are mixed and granulated, they form porous particles in which they are homogeneously dispersed to form independent pores or continuous pores, and rapid introduction of feces and urine into these pores. It promotes the absorption of a large amount of manure and the adsorption of manure on the wall of the pores, and exhibits a high deodorizing degree for manure due to the excellent deodorizing properties of both.
[0026]
(Operation corresponding to claim 2)
(4) Increasing the degree of agglomeration of porous particles that have absorbed manure by containing plant adhesives. The plant adhesive is formed by adhering porous particles together to form a lump, and only the agglomerated portion is taken out and discarded, thereby improving the removal property at the time of disposal.
[0027]
(Operation corresponding to claim 3)
(5) The inclusion of dried okara improves the decomposability in water of breaking up the mass of porous particles that have been agglomerated by absorbing feces and urine, and improves the water washability of the flush toilet.
[0028]
(Operation corresponding to claim 4)
(6) By containing an inorganic filler, the mechanical strength of the porous particles is increased, and the granulated particles are prevented from being disintegrated and pulverized in the distribution to use stage. It can be prevented that it adheres to the sole of the foot and dissipates.
[0029]
Further, the appearance of the animal excrement disposal material can be improved by adding the colorant. Further, by adding a deodorizing agent, it is possible to suppress the faint unique odor of rice bran, defatted rice bran, and vegetable fiber from dried okara. When citric acid is used as a deodorizing agent, the amount added is 5 g for 1 kg of the total flow rate of rice bran, defatted rice bran, vegetable adhesive, inorganic filler and dried okara.
[0030]
Hereinafter, the experimental result which examined optimization of the compounding ratio of each component which comprises the excrement processing material for animals of this invention is demonstrated.
[0031]
Using a compression granulator (production capacity 200 kg / hour, die diameter 3.5 mm), each component of the animal manure treatment material of the present invention example in Table 1 (rice bran, defatted rice bran, corn starch, calcium carbonate and dried okara) Each component (pulp fiber, corn starch and calcium carbonate) of the paper-based animal manure treatment material of the comparative example of Table 2, each component (dried okara and corn starch of the Okara-based animal manure treatment material of the comparative example of Table 3 And calcium carbonate) Each test piece is deodorized with a total weight of 5 kg and an aqueous solution prepared by dissolving 1.5 g of food color blue 1 g, 1 g of yellow No. 4 and 25 g of citric acid in 150 cc of water. Degree, agglomeration degree, and degradability in water were evaluated. Evaluation shows that it gets worse in the order of special, good, good, good, bad.
[0032]
[Table 1]

[0033]
[Table 2]

[0034]
[Table 3]

[0035]
According to Table 1, in the animal manure treatment material of the present invention, the degree of deodorization increases by mixing rice bran and defatted rice bran, and the degree of deodorization increases as the total weight of both increases (Invention Example 2). And 3, Invention Examples 8 and 9) are observed. The more rice bran added to the defatted rice bran, the lower the degree of agglomeration on the non-solidification of the rice bran (Invention Examples 2 and 3, Invention Examples 8 and 9, Invention Example 4, Invention Example 10) ), If the defatted rice bran is excessive relative to the rice bran, the porous granulation becomes insufficient, the water absorption of manure is not sufficient, and the agglomeration degree is low (Invention Example 6, Inventive Example 7, Inventive Example) 12) is allowed.
[0036]
Moreover, according to Table 1, in the animal manure processing material of this invention, when the addition amount of corn starch becomes too small, it is recognized that the degree of agglomeration becomes low (Invention Example 19).
[0037]
Further, according to Table 1, the animal manure treatment material of the present invention has no or too little added amount of dried okara, resulting in poor water degradability (Invention Example 4, Invention Example 7, Invention of the present invention). 10. Invention Example 12, Invention Example 14, Invention Example 15, Invention Example 16) are observed.
[0038]
Further, in Invention Example 21 of Table 1, since the amount of calcium carbonate added was too small, pulverization of porous particles was observed.
[0039]
In addition, in inventive examples 20 and 22 in Table 1, the addition amount of corn starch and calcium carbonate is excessive, and the raw material cost is high. In addition, the present invention examples 1 to 3, 5, 6, 8, 9, 11, 13, and 23 in Table 1 have excessive amounts of addition from dried okara, resulting in high raw material costs.
[0040]
Further, in the animal manure treatment material of the present invention, when using a substitute for corn starch as a plant adhesive and a substitute for calcium carbonate as an inorganic filler, Similar results were obtained.
[0041]
Accordingly, the preferred mixing ratio of the animal manure treating agent of the present invention is 100% total weight (food color and deodorant) of rice bran, defatted rice bran, vegetable adhesives such as corn starch, inorganic fillers such as calcium carbonate, and dried okara. 25% to 35%, more preferably 28% to 32%, optimally 30% for rice bran, 33% to 43%, more preferably 36% to 40% for defatted rice bran 38% optimally, 8-12% for plant adhesives, more preferably 9-11%, optimally 10%, 8-12% for inorganic fillers, more preferably 9 ~ 11%, optimally 10%, for dry okara, 10-14%, more preferably 11-13%, optimally 12%.
[0042]
In Comparative Example A1 of the paper-based animal manure treatment material in Table 2, it is recognized that the deodorization degree of manure is low.
[0043]
In Comparative Example B1 of the okara system animal manure treatment material in Table 3, the deodorization degree of manure is almost good, but the amount of dry okara added is large, and the raw material cost increases.
[0044]
Next, the experimental results of the animal manure treatment material having the optimum mixing ratio described above according to the present invention will be described in detail.
[0045]
(A) Rice bran 1.5kg (30%), defatted rice bran 1.9kg (38%), corn starch 0.5kg (10%), calcium carbonate 0.5kg (10%), dried okara 0.6kg (12%), citric acid 25g Mix and stir for 2 minutes with a mixer, add an aqueous solution prepared by dissolving 1.5 g of blue No. 1 and 1 g of yellow No. 4 with 150 cc of water to this mixture, and mix and stir for another 5 minutes. Into a hopper and discharged from the tip die at a discharge rate of 200 kg / hour to obtain approximately 5 kg of amorphous single piece porous animal feces and urine processing materials colored 3.5 mm in diameter and 4 to 7 mm in length It was. This was adjusted to a treatment material with a moisture content of 7.5%, which was most stabilized as a product in a hot air fluid dryer set at 80 ° C. The water content of the animal excrement disposal material of the present invention obtained by repeating the test is preferably 6 to 9%, more preferably 7 to 8%, and most preferably 7.5%. In addition, as a result of the test use of the animal manure treatment material colored yellow-green for cats, there was no difference in the use situation with no coloring, the pigment was stable after absorption of manure, and the pigment did not flow out.
[0046]
(B) The deodorizing power of the animal manure treatment material obtained in (A) above was examined in the following manner. Add 50 g of animal manure treatment material to a glass Erlenmeyer flask (capacity approx. 3.36 L), add 20 mL of ammonia water (concentration 0.01%), seal tightly and let stand for 1 hour, then adjust the ammonia concentration in the air in the flask. It was measured. As a result, the ammonia concentration was 0.8 ppm, compared with 53.3 ppm when no animal manure treatment material was input, and almost no odor of ammonia could be confirmed.
[0047]
(C) The animal excrement disposal material obtained in the above (A) was spread on a pet toilet container to a depth of about 80 mm, and 20 mL of diluted ammonia water (concentration 0.01%) warmed to 30 ° C. was dropped by a syringe. After 30 minutes, the ammonia water agglomerated into a slightly larger lump than the golf ball at a depth within 50 mm from the top surface, and could be easily removed.
[0048]
(D) As a result of flowing the lump of the above (C) into a flush toilet, it was easily dissociated and decomposed in water, and it could be smoothly washed with water.
[0049]
Although the embodiment of the present invention has been described in detail above, the specific configuration of the present invention is not limited to this embodiment, and the present invention is not limited to the scope of the present invention. include. For example, the animal manure treatment material of the present invention contains rice bran and defatted rice bran, rice bran and defatted rice bran and vegetable adhesive, rice bran and defatted rice bran, vegetable adhesive and dried okara The rice bran, the defatted rice bran, the vegetable adhesive, the dried okara, and the inorganic filler may be used.
[0050]
(Second Embodiment)
The inventor has studied whether rice bran, which is inexpensive and can be expected to have a deodorizing effect, can be used as a raw material, not as an additive, for animal excrement disposal materials. However, rice bran contains oil, so even if granulated rice bran or mixed with other minerals, paper powder, wood flour and okara, it repels moisture and inhibits urine absorption. Therefore, it cannot be used as it is as a raw material for animal excrement disposal materials.
[0051]
The inventor of the present invention paid attention to defatted rice bran, which is a by-product of a fat factory that squeezes rice oil from rice bran. Degreased rice bran, a by-product after oil extraction, has the ability to absorb urine that cannot be obtained with rice bran because it is free of oil and fat, and is a material that is well worth using as a raw material for animal manure treatment materials. It was discovered that it has a deodorizing power. In other words, the present invention is the first to manufacture defatted rice bran as an optimal deodorant material as a raw material for animal excrement treatment materials, and to produce an animal excrement treatment material that has a breakthrough degree of deodorization.
[0052]
The animal manure treatment material of the present invention contains defatted rice bran as a main component.

[0065]
(A) Each component of the animal manure treatment agent of Table 4 to Table 8 (wood powder and defatted rice bran and polymer absorbent, paper powder and defatted rice bran and polymer absorbent, bentonite and defatted rice bran, dried okara and defatted After stirring 2 kg of raw materials (rice bran and corn starch, defatted rice bran and corn starch) with a mixer for 3 minutes, the mixture is fed from a quantitative feeder into a 50 kg / hour compression granulator and extruded from the die diameter, 4 mm in length. It was cut to ˜7 mm, and dipped in a cylindrical pellet-shaped porous particle with a moisture content of 7.5%.
[0066]
(B) The deodorization degree of the animal manure treatment material obtained in (A) above was measured in the following manner. A glass Erlenmeyer flask (capacity 3.36 L) was charged with 50 g of animal manure treatment material, 20 ml of ammonia water (0.01%) was added, sealed, and allowed to stand for 1 hour, and then the ammonia concentration in the flask was measured.
[0067]
In the case of Example 1 in Table 4, wood powder 90%, polymer absorber (adhesive) 10%, non-defatted rice bran 0, ammonia concentration 15.2ppm, in case of Example 5 in Table 4, wood powder 50%, polymer absorption The combination of 10% body (adhesive) and 40% defatted rice bran reduced the ammonia concentration to 1.8 ppm, confirming its surprising deodorizing power.
[0068]
Hereinafter, it was verified that the deodorizing power increased without exception by inclusion of defatted rice bran as shown by the numerical values of ammonia concentrations in Examples 1 to 20 in Tables 4 to 7.
[0069]
In the case of the defatted rice bran 90% and corn starch 10% in Example 21 of Table 8, the granulated pellets are hard and glossy on the surface, and the odor cannot be taken into the pellets, so the deodorization level does not decrease I think that the.
[0070]
In order to use defatted rice bran as a raw material for animal excrement disposal materials, it is desirable to blend with other raw materials and finish it into a porous granule.
[0071]
