Description

本発明は、融雪材に関する。   The present invention relates to a snow melting material.

積雪寒冷地では、融雪期に農地上の積雪面に融雪材を散布して融雪を促進し、農作業の開始時期を早めることが行われている。前記融雪材は、積雪面に散布されて太陽熱を吸収することにより融雪時期を早めるものである。   In snowy cold regions, snow melting material is sprayed on the snow-covered surface of the farm ground during the snow melting period to promote snow melting and advance the start time of farm work. The snow melting material is dispersed on the snow cover surface and absorbs solar heat to accelerate the snow melting time.

従来、前記融雪材として、例えば、肥料用炭酸カルシウム、カーボンブラック、カーボンブラックを付着させた炭酸カルシウム、フライアッシュ、石炭粉、黒色石粉、木炭粉、各種排水処理汚泥の炭化物等が用いられている。ところが、従来の前記融雪材は、融雪効果を上げるために、微細粒子を含んでおり、散布時に該微細粒子が飛散して、作業者やその衣服に付着して作業性、作業環境を悪化させたり、大気汚染を引き起こしたりするという問題がある。   Conventionally, as the snow melting material, for example, calcium carbonate for fertilizer, carbon black, calcium carbonate to which carbon black is attached, fly ash, coal powder, black stone powder, charcoal powder, carbides of various wastewater treatment sludges, and the like have been used. . However, the conventional snow melting material contains fine particles in order to increase the snow melting effect, and the fine particles are scattered when sprayed and adhere to workers and their clothes to deteriorate workability and work environment. Or cause air pollution.

前記問題を解決するために、前記無機材料に比較して比重の大きな貝殻を粉砕して得られた粉体を芯材とし、該芯材にカーボンブラック、石炭粉等の無機材料を結合材を介して結合させた融雪材が提案されている(例えば特許文献1参照)。   In order to solve the above problems, a powder obtained by pulverizing a shell having a specific gravity larger than that of the inorganic material is used as a core material, and an inorganic material such as carbon black or coal powder is used as the core material. There has been proposed a snow melting material joined together (see, for example, Patent Document 1).

一方、前記融雪材は、農地上の積雪面に散布され、積雪を融解させた後は農地に入ることになるため、肥料効果を兼ね備えていることが好ましく、有機農法に使用できる有機農業資材となり得ることがさらに好ましい。ところが、各種排水処理汚泥の炭化物は、化学製品を含む可能性があるため、前記有機農業資材としての使用が難しい。前記肥料効果を兼ね備え、前記有機農業資材となり得る融雪材として、例えば、炭化鶏糞が知られている(例えば特許文献2参照)。   On the other hand, since the snow melting material is sprayed on the snow surface of the farm and melts the snow, the snow melting material enters the farm land. Therefore, the snow melting material preferably has a fertilizer effect and becomes an organic agricultural material that can be used for organic farming. More preferably, it is obtained. However, since the carbides of various wastewater treatment sludges may contain chemical products, they are difficult to use as the organic agricultural material. For example, carbonized chicken manure is known as a snow melting material that has the fertilizer effect and can be the organic agricultural material (see, for example, Patent Document 2).

そこで、前記貝殻を粉砕して得られた粉体に、前記炭化鶏糞を結合させることができれば、飛散しにくい融雪材に肥料効果を付与することができ、さらに前記有機農業資材となり得るので好都合である。   Therefore, if the carbonized chicken dung can be combined with the powder obtained by pulverizing the shell, it is possible to provide a fertilizer effect to the snow melting material that is difficult to scatter, and it can be used as the organic agricultural material. is there.

しかしながら、従来、前記貝殻を粉砕して得られた粉体に、前記炭化鶏糞を結合させる結合材として適切なものが無く、該貝殻を粉砕して得られた粉体と該炭化鶏糞とを十分な強度で結合させることが難しいという不都合がある。前記結合材として、工業的に用いられるそれ自体公知の化学製品を用いれば十分な強度を得ることはできるが、該化学製品を用いた融雪材は、有機農法に使用できる有機農業資材とはなり得ない。

However, the powder obtained by pulverizing the shell is not suitable as a binding material for binding the carbonized chicken dung, and the powder obtained by pulverizing the shell and the carbonized chicken dung are sufficiently used. There is an inconvenience that it is difficult to bond with a strong strength. A sufficient strength can be obtained by using an industrially known chemical product used in the industry as the binder, but a snow melting material using the chemical product is not an organic agricultural material that can be used in organic farming. I don't get it.
JP 62-151485 A JP 2002-266328 A

本発明は、かかる不都合を解消して、貝殻またはウニ殻を粉砕して得られた粉体と炭化鶏糞とが十分な強度で結合しており、飛散しにくく、有機農業資材として有機農法に使用できる融雪材を提供することを目的とする。   The present invention eliminates such inconvenience, and the powder obtained by pulverizing shells or sea urchin shells and carbonized chicken manure are combined with sufficient strength, are not easily scattered, and are used for organic farming as an organic agricultural material. An object is to provide a snow melting material that can be used.

かかる目的を達成するために、本発明の融雪材は、貝殻またはウニ殻を粉砕した粉体と、炭化鶏糞を粉砕した粉体と、スラリー状とした魚介類の内臓とを混合し、加圧して得られた粒子を加熱した後、解砕してなることを特徴とする。   In order to achieve such an object, the snow melting material of the present invention mixes and pressurizes a powder obtained by pulverizing a shell or sea urchin shell, a powder obtained by pulverizing carbonized chicken dung, and a slurry of seafood internal organs. The obtained particles are heated and then crushed.

本発明の融雪材は、前記貝殻またはウニ殻を粉砕した粉体と、前記炭化鶏糞を粉砕した粉体と、前記スラリー状とした魚介類の内臓とを混合し、加圧成形することにより造粒される。前記造粒により得られた粒子は、次いで加熱されることにより、前記スラリー状とした魚介類の内臓が乾燥される。この結果、前記魚介類の内臓は、前記貝殻またはウニ殻を粉砕した粉体と、前記炭化鶏糞を粉砕した粉体とを結合する結合材として作用し、該貝殻またはウニ殻を粉砕した粉体と、該炭化鶏糞を粉砕した粉体とが結合される。   The snow melting material of the present invention is produced by mixing the powder obtained by pulverizing the shell or sea urchin shell, the powder obtained by pulverizing the carbonized chicken dung, and the internal organs of the fishery product in a slurry state, and pressing the mixture. Be grained. The particles obtained by the granulation are then heated to dry the visceral fish and shellfish. As a result, the internal organs of the seafood act as a binding material that combines the powder obtained by pulverizing the shell or sea urchin shell and the powder obtained by pulverizing the carbonized chicken dung, and the powder obtained by pulverizing the shell or sea urchin shell. And powder obtained by pulverizing the carbonized chicken dung are combined.

このとき、前記魚介類の内臓は大量のタンパク質を含んでおり、該タンパク質が前記加熱により硬化する。従って、前記貝殻またはウニ殻を粉砕した粉体と、前記炭化鶏糞を粉砕した粉体とを強固に結合させることができる。   At this time, the internal organs of the fish and shellfish contain a large amount of protein, and the protein is cured by the heating. Therefore, the powder obtained by pulverizing the shell or sea urchin shell and the powder obtained by pulverizing the carbonized chicken dung can be firmly bonded.

そして、前記加熱により得られた粒子を解砕することにより、融雪に適した粒子径を備える融雪材とすることができる。   And it can be set as the snow melting material provided with the particle diameter suitable for snow melting by crushing the particle | grains obtained by the said heating.

本発明の融雪材は、前記魚介類の内臓が結合材として作用するので、前記貝殻またはウニ殻を粉砕した粉体と前記炭化鶏糞を粉砕した粉体との間で十分な結合強度を得ることができ、該貝殻またはウニ殻を粉砕した粉体を含むことにより比重が大きくなり飛散しにくくなる。また、本発明の融雪材は、原料に化学製品を用いることがないので、有機農業資材として有機農法に使用することができる。   In the snow melting material of the present invention, since the internal organs of the seafood act as a binding material, sufficient binding strength is obtained between the powder obtained by pulverizing the shell or sea urchin shell and the powder obtained by pulverizing the carbonized chicken dung. Including the powder obtained by pulverizing the shell or sea urchin shell increases the specific gravity and makes it difficult to scatter. Moreover, since the snow melting material of this invention does not use a chemical product for a raw material, it can be used for organic farming as an organic agricultural material.

本発明の融雪材は、全体の40〜70重量%の貝殻またはウニ殻を粉砕した粉体と、全体の10〜40重量%の炭化鶏糞を粉砕した粉体と、全体の10〜40重量%のスラリー状とした魚介類の内臓とを混合することが好ましい。また、本発明の融雪材は、全体の50〜60重量%の貝殻またはウニ殻を粉砕した粉体と、全体の20〜30重量%の炭化鶏糞を粉砕した粉体と、全体の10〜30重量%のスラリー状とした魚介類の内臓とを混合することがさらに好ましい。   The snow melting material of the present invention comprises a powder obtained by pulverizing 40 to 70% by weight of the whole shell or sea urchin shell, a powder obtained by pulverizing 10 to 40% by weight of the carbonized chicken dung, and 10 to 40% by weight of the whole. It is preferable to mix the slurries of fish and shellfish. Moreover, the snow melting material of this invention is the powder which grind | pulverized the whole shell shell or sea urchin shell of 50 to 60 weight%, the powder which grind | pulverized 20 to 30 weight% of the whole carbonized chicken manure, and the whole 10-30. It is more preferable to mix with the internal organs of fish and shellfish in the form of a slurry by weight.

前記混合時に、前記貝殻またはウニ殻を粉砕した粉体の量が全体の40重量%未満であると、得られた融雪材が飛散しやすいものになることがある。また、前記貝殻またはウニ殻を粉砕した粉体の量が全体の70重量%を超えると、得られた融雪材において相対的に前記炭化鶏糞の量が低減して十分な融雪効果と肥料効果とが得られなくなったり、相対的に前記魚介類の内臓の量が低減して十分な結合強度及び十分な肥料効果が得られなくなったりすることがある。   When the amount of the powder obtained by pulverizing the shell or sea urchin shell is less than 40% by weight during the mixing, the obtained snow melting material may be easily scattered. Moreover, when the amount of the powder obtained by pulverizing the shell or sea urchin shell exceeds 70% by weight, the amount of the carbonized chicken manure is relatively reduced in the obtained snow melting material, and sufficient snow melting effect and fertilizer effect are obtained. May not be obtained, or the amount of visceral organs of the fish and shellfish may be relatively reduced, and a sufficient binding strength and a sufficient fertilizer effect may not be obtained.

前記混合時に、前記炭化鶏糞の量が全体の10重量%未満であると、得られた融雪材において十分な融雪効果と肥料効果とが得られないことがある。また、前記炭化鶏糞の量が全体の40重量%を超えると、融雪効果に及ぼす影響が少なくなり、また得られた融雪材においてリンの含有量が過大になり環境汚染の原因となることがある。   When the amount of the carbonized chicken manure is less than 10% by weight during mixing, sufficient snow melting effect and fertilizer effect may not be obtained in the obtained snow melting material. Moreover, when the amount of the carbonized chicken manure exceeds 40% by weight of the whole, the influence on the snow melting effect is reduced, and the content of phosphorus in the obtained snow melting material becomes excessive, which may cause environmental pollution. .

前記混合時に、前記スラリー状とした魚介類の内臓の量が全体の10重量%未満であると、得られた融雪材において十分な結合強度が得られないことがある。また、前記スラリー状とした魚介類の内臓の量が全体の40重量%を超えると、得られた融雪材において十分な融雪効果が得られないことがある。   When the amount of the internal organs of the fish and shellfish in the slurry state is less than 10% by weight at the time of mixing, sufficient bonding strength may not be obtained in the obtained snow melting material. Moreover, when the amount of the internal organs of the fish and shellfish in the slurry form exceeds 40% by weight, a sufficient snow melting effect may not be obtained in the obtained snow melting material.

さらに、本発明の融雪材は、100μm以上1180μm未満の範囲の粒子径を有することが好ましい。本発明の融雪材は、粒子径が100μm未満であると飛散しやすくなる。また、本発明の融雪材は、粒子径が1180μm以上であると、十分な融雪効果が得られないことがある。   Furthermore, the snow melting material of the present invention preferably has a particle size in the range of 100 μm or more and less than 1180 μm. The snow melting material of the present invention is likely to be scattered when the particle diameter is less than 100 μm. Moreover, if the particle diameter of the snow melting material of this invention is 1180 micrometers or more, sufficient snow melting effect may not be acquired.

次に、添付の図面を参照しながら本発明の実施の形態についてさらに詳しく説明する。図1は本実施形態の融雪材の製造方法を示すフローチャートであり、図2は本実施形態の融雪材の構成を示す説明的断面図であり、図3及び図4は本実施形態の融雪材の肥料効果を示すグラフである。   Next, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. FIG. 1 is a flowchart showing a method for producing a snow melting material of the present embodiment, FIG. 2 is an explanatory sectional view showing the configuration of the snow melting material of the present embodiment, and FIGS. 3 and 4 are snow melting materials of the present embodiment. It is a graph which shows the fertilizer effect of.

本実施形態の融雪材は、貝殻またはウニ殻を粉砕した粉体と、炭化鶏糞を粉砕した粉体と、スラリー状とした魚介類の内臓とを混合し、加圧して得られた粒子を加熱した後、粉砕してなるものである。   The snow melting material of the present embodiment is a mixture of a powder obtained by pulverizing shell or sea urchin shell, a powder obtained by pulverizing carbonized chicken dung, and a slurry of fish and shellfish, and heating the particles obtained by pressurization. And then pulverized.

本実施形態の融雪材を製造するときは、まず、図1に示すように、貝殻またはウニ殻(以下、「貝殻・ウニ殻」と記載する)1を粉砕機2で粒子径が600μm未満となるように粉砕する。前記貝殻としては、例えば、ホタテガイ、カキ、アワビガイ、ホッキガイ等の貝類の貝殻を用いることができる。貝殻・ウニ殻1は、粉砕機2での粉砕効率を向上させるために、予め水分5重量%以下に乾燥させ、最大径が50mm以下程度になるように粗粉砕することが好ましい。粉砕機2は、貝殻・ウニ殻1を600μm未満の粒子径に粉砕できるものであればどのようなものでもよいが、良好な粉砕効率が得られることから衝撃式粉砕機、例えばハンマーミルが好ましい。   When producing the snow melting material of the present embodiment, first, as shown in FIG. 1, a shell or sea urchin shell (hereinafter referred to as “shell / sea urchin shell”) 1 is pulverized by a grinder 2 to have a particle diameter of less than 600 μm. Grind to make Examples of the shell include shells of shells such as scallops, oysters, abalone mussels, and sea breams. In order to improve the pulverization efficiency in the pulverizer 2, the shell / sea urchin shell 1 is preferably dried in advance to a moisture content of 5% by weight or less and coarsely pulverized so that the maximum diameter is about 50 mm or less. The pulverizer 2 may be anything as long as it can pulverize the shell and sea urchin shells 1 to a particle diameter of less than 600 μm, but an impact pulverizer such as a hammer mill is preferable because good pulverization efficiency can be obtained. .

次に、粉砕機2で粉砕された貝殻・ウニ殻1を目開き600μmの振動篩3で分級し、粒子径600μm未満の貝殻・ウニ殻粉体4aを貝殻・ウニ殻粉体タンク5に収容する。一方、振動篩3上に残った粒子径600μmを超える粒子4bは、粉砕機2に戻される。   Next, the shell / urchin shell 1 pulverized by the pulverizer 2 is classified by the vibrating sieve 3 having an opening of 600 μm, and the shell / urchin shell powder 4 a having a particle diameter of less than 600 μm is stored in the shell / urchin shell powder tank 5. To do. On the other hand, the particles 4b having a particle diameter exceeding 600 μm remaining on the vibrating sieve 3 are returned to the pulverizer 2.

次に、炭化鶏糞6を乾燥機7で乾燥した後、粉砕機8で粒子径が150μm未満となるように粉砕する。炭化鶏糞6は、本実施形態の融雪材に対して、太陽熱を吸収する効果と、肥料成分としてのリン酸分とを付与するものであり、例えば500〜800℃程度の温度で炭化され、10重量%程度の水分を含むものを用いることができる。このような炭化鶏糞6として市販品を用いてもよい。   Next, after carbonized chicken manure 6 is dried with a dryer 7, it is pulverized with a pulverizer 8 so that the particle diameter is less than 150 μm. The carbonized chicken manure 6 gives the snow melting material of this embodiment an effect of absorbing solar heat and a phosphoric acid component as a fertilizer component, and is carbonized at a temperature of about 500 to 800 ° C., for example. The thing containing the water | moisture content of about weight% can be used. A commercial item may be used as such carbonized chicken manure 6.

乾燥機7としては、例えば熱風乾燥機を用いることができる。乾燥機7は、炭化鶏糞6の水分を例えば2.5重量%程度に乾燥させることにより、後工程での目詰まりを防止すると共に、粉砕を容易にすることができる。粉砕機8は、炭化鶏糞6を150μm未満の粒子径に粉砕できるものであればどのようなものでもよいが、良好な粉砕効率が得られることから衝撃式粉砕機、例えばハンマーミルが好ましい。   As the dryer 7, for example, a hot air dryer can be used. The dryer 7 can prevent clogging in a subsequent process and facilitate crushing by drying the moisture of the carbonized chicken dung 6 to, for example, about 2.5% by weight. The pulverizer 8 may be anything as long as it can pulverize the carbonized chicken feces 6 to a particle diameter of less than 150 μm, but an impact pulverizer such as a hammer mill is preferable because good pulverization efficiency can be obtained.

次に、粉砕機8で粉砕された炭化鶏糞6を目開き150μmの振動篩9で分級し、粒子径150μm未満の炭化鶏糞粉体10aを炭化物粉体タンク11に収容する。一方、振動篩9上に残った粒子径150μmを超える粒子10bは、粉砕機8に戻される。   Next, the carbonized chicken droppings 6 pulverized by the crusher 8 are classified by a vibrating sieve 9 having an opening of 150 μm, and the carbonized chicken droppings 10 a having a particle diameter of less than 150 μm are stored in the carbide powder tank 11. On the other hand, the particles 10b having a particle diameter exceeding 150 μm remaining on the vibrating sieve 9 are returned to the pulverizer 8.

次に、魚介類の内臓12をミンサー13によりスラリー(泥しょう)状とし、結合材タンク14に収容する。魚介類の内臓12は、本実施形態の融雪材に対して、貝殻・ウニ殻粉体4aと炭化鶏糞粉体10aとの間での十分な結合強度と、肥料成分としての窒素分とを付与するものであり、魚介類の加工残渣を用いることができる。魚介類の内臓12は、植物の生育に対する悪影響を無くすため、油脂分及び重金属類の含有量の少ないものが好ましく、一般に肝臓は好ましくない。このような魚介類の内臓12としては、再利用がほとんど行われておらず大量に入手することができることから、ホタテガイ生殖巣(オス)、サケの内臓、タラの内臓等が好ましい。   Next, the internal organs 12 of the seafood is made into a slurry (mud) form by the mincer 13 and accommodated in the binder tank 14. The internal organs 12 of the seafood impart sufficient bonding strength between the shell / urchin shell powder 4a and the carbonized chicken manure powder 10a and the nitrogen content as a fertilizer component to the snow melting material of this embodiment. The processing residue of seafood can be used. In order to eliminate the adverse effects on the growth of plants, the seafood internal organs 12 are preferably those having a low content of fats and oils and heavy metals, and the liver is generally not preferred. Such seafood internal organs 12 are preferably scallop gonads (male), salmon internal organs, cod internal organs and the like because they are hardly reused and can be obtained in large quantities.

魚介類の内臓12をスラリー状とする場合、冷凍した状態で処理することにより、冷凍していない状態のときよりも微細化することができる。従って、魚介類の内臓12は、−10℃以下の冷凍した状態でミンサー13によりスラリー状とすることが好ましい。尚、魚介類の内臓12は、ミンサー13に代えて磨砕機を用いてスラリー状としてもよい。   When making the internal organs 12 of a seafood into a slurry state, by processing it in the frozen state, it can be made finer than when it is not frozen. Therefore, it is preferable that the seafood internal organs 12 be slurried with the mincer 13 in a frozen state at −10 ° C. or lower. The seafood internal organs 12 may be made into a slurry using a grinder instead of the mincer 13.

次に、貝殻・ウニ殻粉体タンク5に収容されている貝殻・ウニ殻粉体4aと、炭化物粉体タンク11に収容されている炭化鶏糞粉体10aと、結合材タンク14に収容されているスラリー状の魚介類の内臓12とを、所定量ずつ混練機15に供給して混合する。混練機15としては、例えば双腕型混練機(双腕型捏化機)を用いることができる。   Next, the shell / urchin shell powder 4a stored in the shell / urchin shell powder tank 5, the carbonized chicken manure powder 10a stored in the carbide powder tank 11, and the binder tank 14 are stored. The slurry-like internal organs 12 of the seafood are supplied to the kneader 15 by a predetermined amount and mixed. As the kneader 15, for example, a double-arm kneader (double-arm hatcher) can be used.

このとき、貝殻・ウニ殻粉体4aの量は、前記混合により得られる混合物全体の40〜70重量%とすることが好ましく、50〜60重量%とすることがさらに好ましい。また、炭化鶏糞粉体10aの量は、前記混合により得られる混合物全体の10〜40重量%とすることが好ましく、20〜30重量%とすることがさらに好ましい。また、スラリー状の魚介類の内臓12の量は、前記混合により得られる混合物全体の10〜40重量%とすることが好ましく、10〜30重量%とすることがさらに好ましい。   At this time, the amount of the shell / sea urchin shell powder 4a is preferably 40 to 70% by weight, more preferably 50 to 60% by weight of the total mixture obtained by the mixing. Moreover, it is preferable to set it as 10-40 weight% of the whole mixture obtained by the said mixing, and, as for the quantity of the carbonized chicken dung powder 10a, it is more preferable to set it as 20-30 weight%. In addition, the amount of the slurry-like seafood internal organs 12 is preferably 10 to 40% by weight, more preferably 10 to 30% by weight, based on the total mixture obtained by the mixing.

前記混合に当たっては、前記の量の貝殻・ウニ殻粉体4aと、炭化鶏糞粉体10aと、スラリー状の魚介類の内臓12とを同時に混練機15に供給するようにしてもよいが、まず、貝殻・ウニ殻粉体4aと、スラリー状とした魚介類の内臓12とを混練機15に供給し、所定時間混合することが好ましい。このようにすると、貝殻・ウニ殻粉体4aの表面がスラリー状の魚介類の内臓12により均一に被覆される。   In the mixing, the above-mentioned amount of shellfish / sea urchin shell powder 4a, carbonized chicken manure powder 10a, and slurry-like seafood internal organs 12 may be simultaneously supplied to the kneader 15. It is preferable that the shellfish / sea urchin shell powder 4a and the slurry-like seafood internal organs 12 are supplied to the kneader 15 and mixed for a predetermined time. In this way, the surface of the shell / sea urchin shell powder 4a is uniformly coated with the slurry-like seafood internal organs 12.

そこで、次に、炭化鶏糞粉体10aを供給してさらに所定時間混合すると、貝殻・ウニ殻粉体4aの表面を被覆しているスラリー状の魚介類の内臓12の上に炭化鶏糞粉体10aが付着し、貝殻・ウニ殻粉体4aと炭化鶏糞粉体10aとがスラリー状の魚介類の内臓12を介して接着される。   Then, when carbonized chicken manure powder 10a is supplied and further mixed for a predetermined time, the carbonized chicken manure powder 10a is placed on the slurry-like seafood internal organs 12 covering the surface of the shell / sea urchin shell powder 4a. Is attached, and the shell / urchin shell powder 4a and the carbonized chicken manure powder 10a are bonded together via the slurry-like internal organs 12 of the seafood.

また、前記混合に当たっては、貝殻・ウニ殻粉体4aと、炭化鶏糞粉体10aと、スラリー状の魚介類の内臓12とを混練機15に供給した後、さらに水分調整を行うことが好ましい。前記水分調整は、水タンク16から水を添加することにより、前記混合により得られる混合物の含有する水分が該混合物全体の35〜50%となるようにする。このようにすることにより、次工程の造粒操作を良好に行うことができる。   In the mixing, it is preferable to further adjust the water content after supplying the shell / sea urchin shell powder 4a, the carbonized chicken manure powder 10a, and the slurry-like seafood internal organs 12 to the kneader 15. In the moisture adjustment, water is added from the water tank 16 so that the moisture contained in the mixture obtained by the mixing is 35 to 50% of the entire mixture. By doing in this way, granulation operation of the next process can be performed favorably.

次に、前記混合により得られた混合物を、造粒機17に供給し、加圧造粒する。このようにすることにより、スラリー状の魚介類の内臓12を介して接着されている貝殻・ウニ殻粉体4aと炭化鶏糞粉体10aとを強固に結合させることができ、また次工程の乾燥の効率を向上させることができる。   Next, the mixture obtained by the mixing is supplied to the granulator 17 and subjected to pressure granulation. By doing in this way, the shell-sea urchin shell powder 4a and the carbonized chicken manure powder 10a adhered through the slurry-like seafood internal organs 12 can be firmly bonded, and drying in the next step is also possible. Efficiency can be improved.

次に、造粒機17で造粒された粒子を乾燥機18で乾燥する。乾燥機18としては、例えば熱風乾燥機を用いることができ、乾燥機の種類、乾燥する融雪材の量にもよるが、例えば、前記粒子を120〜150℃の範囲の温度で、2〜10時間の範囲の時間、加熱して乾燥する。前記乾燥は、乾燥後の粒子の水分が10重量%以下、好ましくは5重量%以下となるように行う。   Next, the particles granulated by the granulator 17 are dried by a dryer 18. As the dryer 18, for example, a hot air dryer can be used. Depending on the type of the dryer and the amount of the snow melting material to be dried, for example, the particles are heated at a temperature in the range of 120 to 150 ° C. Heat to dry for a time range. The drying is performed so that the moisture of the particles after drying is 10% by weight or less, preferably 5% by weight or less.

前記乾燥により、魚介類の内臓12が固化し、貝殻・ウニ殻粉体4aと炭化鶏糞粉体10aとが魚介類の内臓12を結合材として強固に結合された粒子が得られる。また、このとき、魚介類の内臓12に含まれるタンパク質が熱で硬化するので、貝殻・ウニ殻粉体4aと炭化鶏糞粉体10aとがさらに強固に結合される。   By the drying, the internal organs 12 of the seafood are solidified, and particles in which the shell / sea urchin shell powder 4a and the carbonized chicken manure powder 10a are firmly bonded using the internal organs 12 of the seafood as a binder are obtained. At this time, since the protein contained in the internal organs 12 of the seafood is hardened by heat, the shell / sea urchin powder 4a and the carbonized chicken manure powder 10a are more firmly bonded.

また、前記乾燥では、乾燥後の粒子の水分を前記範囲とすることにより、魚介類の内臓12の腐敗を防止して保存性を向上させることができると共に、輸送効率を向上させることができる。   Moreover, in the said drying, by making the water | moisture content of the particle | grains after drying into the said range, it can prevent the decay of the internal organs 12 of fishery products, can improve preservability, and can improve transport efficiency.

前記乾燥後の粒子は顆粒状になっているので、融雪に適した大きさとするために、解砕機19に供給して解砕し、細粒化する。解砕機19としては、融雪に適した大きさの粒子を得るために、回転数の比較的遅い衝撃式解砕機または切断式解砕機が適している。   Since the particles after drying are in the form of granules, they are supplied to the crusher 19 to be crushed and finely divided so as to have a size suitable for melting snow. As the crusher 19, in order to obtain particles having a size suitable for melting snow, an impact crusher or a cutting crusher having a relatively low rotational speed is suitable.

前記細粒化された粒子は、融雪効果を得るために、粒子径が1180μm未満であることが好ましい。一方、前記細粒化された粒子は、飛散を防止するために、粒子径が100μm以上であることが好ましい。   The finely divided particles preferably have a particle diameter of less than 1180 μm in order to obtain a snow melting effect. On the other hand, the finely divided particles preferably have a particle diameter of 100 μm or more in order to prevent scattering.

そこで、次に前記細粒化された粒子を、目開き100μmと1180μmとの振動篩20で分級し、粒子径100μm以上1180μm未満の粒子21aを融雪材22として回収する。振動篩20上に残った粒子径1180μm以上の粒子21bは、解砕機19に戻される。一方、振動篩20を通過した粒子径100μm未満の粒子21cは、混練機15に戻される。   Then, the finely divided particles are classified by the vibrating sieve 20 having an opening of 100 μm and 1180 μm, and the particles 21 a having a particle diameter of 100 μm or more and less than 1180 μm are collected as the snow melting material 22. The particles 21b having a particle diameter of 1180 μm or more remaining on the vibrating sieve 20 are returned to the crusher 19. On the other hand, the particles 21 c having a particle diameter of less than 100 μm that have passed through the vibrating sieve 20 are returned to the kneader 15.

以上のようにして得られた融雪材22は、図2(a)に示す融雪材22aと、図2(b)に示す融雪材22bとの混合物になっている。ここで、融雪材22aは、図2(a)に示すように、比較的大きな貝殻・ウニ殻粉体4aの粒子を芯材として、貝殻・ウニ殻粉体4aの周囲に、比較的小さな炭化鶏糞粉体10aの粒子が、固化した魚類の内臓12を結合材として結合している。また、融雪材22bは、図2(b)に示すように、比較的小さな貝殻・ウニ殻粉体4aの粒子と、炭化鶏糞粉体10aの粒子とが、固化した魚類の内臓12を結合材として結合している。   The snow melting material 22 obtained as described above is a mixture of the snow melting material 22a shown in FIG. 2 (a) and the snow melting material 22b shown in FIG. 2 (b). Here, as shown in FIG. 2 (a), the snow melting material 22a has a relatively small carbonization around the shell / urchin shell powder 4a with the particles of the relatively large shell / urchin shell powder 4a as a core material. The particles of the chicken manure powder 10a are combined with the solidified fish internal organs 12 as a binder. Further, as shown in FIG. 2 (b), the snow melting material 22b is a binding material for the fish internal organs 12 in which the relatively small shell / urchin shell powder 4a particles and the carbonized chicken manure powder 10a particles are solidified. Are bound as.
