Description
本発明は、石灰窒素質粒状肥料の製造方法に関する。 The present invention relates to a method for producing a lime nitrogen granular fertilizer.
石灰窒素単独、又はこの基材と熔成燐肥、焼成燐肥、過燐酸石灰、塩化カリウム、硫酸カリウム等の肥料成分とが複合化された石灰窒素を含む肥料を造粒するには、古くから尿素をバインダーとする加圧成形法が知られているが、造粒原料の予備加熱、加圧成形等に多大なエネルギーを必要とした。そこで、これを解決し、また造粒物の粉化抑制をするために、大豆硬化油、ステアリルアルコール、オレイン酸ナトリウム、天然パラフィン及びピッチの群から選ばれた少なくとも１種類の滑剤を、造粒原料１００質量部あたり０．２〜５質量部用いる押出成形法が提案されている（特許文献１）。
しかし、これらの滑剤にあっては、その種類によって造粒原料の流動作用が著しく違い、流動作用の大きいものを使用したときには、配管内やホッパー内での詰まりは軽減されるが、予備加熱工程では撹拌翼による撹拌効率が落ちて目標温度までの昇温に時間が掛かるという問題があり、流動作用の小さいものを使用したときには、この逆現象があった。そのため、配管やホッパー内での原料残存が少なく、しかも予備加熱時の昇温を短時間で済ませることができなかった。更には、これらの滑剤を用いて所望の粒硬度と粒度を有する造粒肥料を製造するには、比較的多量の尿素を必要としたので、石灰窒素の肥料効果と農薬効果が損なわれた。 However, in these lubricants, the flow action of the granulated raw material varies greatly depending on the type, and when a large flow action is used, clogging in the pipe and hopper is reduced, but the preheating step However, there is a problem that the stirring efficiency by the stirring blades is lowered and it takes time to raise the temperature to the target temperature, and this reverse phenomenon occurs when a thing having a small fluidity is used. For this reason, there are few raw materials remaining in the pipes and hoppers, and the temperature increase during the preliminary heating cannot be completed in a short time. Furthermore, since a relatively large amount of urea was required to produce a granulated fertilizer having desired grain hardness and particle size using these lubricants, the fertilizer effect and agricultural chemical effect of lime nitrogen were impaired.
本発明の目的は、上記に鑑み、配管やホッパー内での原料残存が少なく、しかも予備加熱時間を短縮することができ、また尿素バインダーの使用量を低減する効果も期待できる石灰窒素質粒状肥料の製造方法を提供することである。 In view of the above, the object of the present invention is to reduce the amount of raw material remaining in pipes and hoppers, reduce the preheating time, and expect the effect of reducing the amount of urea binder used. It is to provide a manufacturing method.
すなわち、本発明は、石灰窒素を含む肥料に尿素と滑剤を混合し、それを押出成形して造粒肥料を製造するにあたり、滑剤として脂肪酸類と脂肪酸エステルとを以下の組合せ１又は組合せ２にして併用すること、滑剤の使用量が、石灰窒素を含む肥料と尿素と滑剤との合計１００質量部あたり０．４〜２．０質量部であり、脂肪酸類／脂肪酸エステルの質量比が０．２〜２．０であること、を特徴とする石灰窒素質粒状肥料の製造方法である。
［組合せ１］
脂肪酸類が、ステアリン酸、ステアリン酸のアルカリ金属塩及びステアリン酸のアルカリ土類金属塩から選ばれた１種類以上であり、脂肪酸エステルがグリセリン脂肪酸エステル、コハク酸脂肪酸エステル、ショ糖脂肪酸エステル、及びソルビタン脂肪酸エステルから選ばれた１種類以上であること。
［組合せ２］
脂肪酸類が、ラウリン酸、ミリスチン酸、パルミチン酸、オレイン酸、ベヘニン酸、これらの脂肪酸のアルカリ金属塩及びこれらの脂肪酸のアルカリ土類金属塩から選ばれた１種類以上であり、脂肪酸エステルがグリセリン脂肪酸エステルであること。
本発明においては、脂肪酸類がステアリン酸、脂肪酸エステルがグリセリン脂肪酸エステルであり、それらの合計の使用量が０．６〜１．３質量部であり、脂肪酸類／脂肪酸エステルの質量比が０．２〜１．０であることが好ましい。
That is, the present invention is to mix urea and lubricant fertilizer containing lime nitrogen, when extruding it to produce granulated fertilizer, the fatty acids and fatty acid esters to combination 1 or combination 2 below as a lubricant The amount of lubricant used is 0.4 to 2.0 parts by mass per 100 parts by mass in total of the fertilizer containing lime nitrogen, urea and lubricant, and the mass ratio of fatty acids / fatty acid ester is 0.00 . It is a manufacturing method of the lime nitrogenous granular fertilizer characterized by being 2-2.0 .
[Combination 1]
The fatty acid is at least one selected from stearic acid, alkali metal salt of stearic acid and alkaline earth metal salt of stearic acid, the fatty acid ester is glycerin fatty acid ester, succinic acid fatty acid ester, sucrose fatty acid ester, and It should be at least one selected from sorbitan fatty acid esters.
[Combination 2]
The fatty acid is at least one selected from lauric acid, myristic acid, palmitic acid, oleic acid, behenic acid, alkali metal salts of these fatty acids and alkaline earth metal salts of these fatty acids, and the fatty acid ester is glycerin Be fatty acid ester.
In the present invention, the fatty acids are stearic acid, the fatty acid ester is glycerin fatty acid ester, the total amount used is 0.6 to 1.3 parts by mass, and the mass ratio of fatty acids / fatty acid ester is 0.00. It is preferable that it is 2-1.0.
本発明によれば、上記目的を達成することができる。 According to the present invention, the above object can be achieved.
本発明で用いられる石灰窒素を含む肥料は、石灰窒素単独、又はこれと熔成燐肥、焼成燐肥、過燐酸石灰、塩化カリウム、硫酸カリウム等の肥料成分との混合原料である。本発明では、この石灰窒素を含む肥料に特定２種類の滑剤の所定量を存在させ、尿素をバインダーとして造粒するものである。滑剤の使用量は、上記石灰窒素を含む肥料と尿素と滑剤との合計１００質量部あたり０．４〜２．０質量部である。０．４質量部未満では、造粒する際の加圧抵抗が増大し、また２．０質量部をこえると、加圧抵抗が低下しすぎ、いずれの場合も造粒が困難となる。特に好ましい滑剤の使用量は、０．６〜１．３質量部であり、中でも脂肪酸類／脂肪酸エステルの質量比を０．２〜１．０とすることである。 The fertilizer containing lime nitrogen used in the present invention is lime nitrogen alone or a mixed raw material with fertilizer components such as molten phosphorous fertilizer, calcined phosphorous fertilizer, lime perphosphate, potassium chloride, and potassium sulfate. In the present invention, a predetermined amount of two specific types of lubricant is present in the fertilizer containing lime nitrogen and granulated using urea as a binder. The usage-amount of a lubricant is 0.4-2.0 mass parts per 100 mass parts in total of the fertilizer containing the said lime nitrogen, urea, and a lubricant. If the amount is less than 0.4 parts by mass, the pressure resistance during granulation increases. If the amount exceeds 2.0 parts by mass, the pressure resistance decreases too much, and in either case, granulation becomes difficult. A particularly preferable amount of the lubricant used is 0.6 to 1.3 parts by mass, and among them, the mass ratio of fatty acids / fatty acid ester is 0.2 to 1.0.
本発明においては、滑剤として、脂肪酸又はその塩から選ばれた脂肪酸類の１種類以上と、脂肪酸エステルの１種類以上とを、上記組合せ１又は組合せ２として併用される。これらは、別々に造粒原料に添加してもよく、また予混合してから添加してもよい。 In the present invention, as the lubricant, one or more kinds of fatty acids selected from fatty acids or salts thereof and one or more kinds of fatty acid esters are used in combination as the above combination 1 or combination 2 . These may be added separately to the granulation raw material, or may be added after premixing.
脂肪酸類としては、ラウリン酸、ミリスチン酸、パルミチン酸、ステアリン酸、オレイン酸、ベヘニン酸及びこれらの酸のナトリウム、カリウム、カルシウム、マグネシウム等のアルカリ金属塩又はアルカリ土類金属塩である。特に好ましくは、ステアリン酸である。脂肪酸エステルとしては、グリセリン脂肪酸エステル、コハク酸脂肪酸エステル、ショ糖脂肪酸エステル、ソルビタン脂肪酸エステルである。中でも、分子内に脂肪酸エステルを複数持っている、トリステアリン、ジステアリンなどが好ましい。工業的にはトリアシルグリセリンが好適である。 Examples of fatty acids include lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, behenic acid, and alkali metal salts or alkaline earth metal salts of these acids such as sodium, potassium, calcium, and magnesium. Particularly preferred is stearic acid. Examples of the fatty acid ester include glycerin fatty acid ester, succinic acid fatty acid ester, sucrose fatty acid ester, and sorbitan fatty acid ester. Of these, tristearin and distearin having a plurality of fatty acid esters in the molecule are preferable. Industrially, triacylglycerol is preferable.
尿素の使用量は、上記石灰窒素を含む肥料１００質量部あたり、５〜２０質量部、特に８〜１２質量部であることが好ましい。 It is preferable that the usage-amount of urea is 5-20 mass parts per 100 mass parts of fertilizers containing the said lime nitrogen, especially 8-12 mass parts.
本発明で使用される押出成形機は、スクリュー型、回転多孔ダイス、回転ブレード等でいずれでも可能である。回転多孔ダイスを用いる成形法によれば、直径約３ｍｍ、長さ２〜７ｍｍ程度の円柱状造粒物が製造される。 The extruder used in the present invention can be any of a screw type, a rotary porous die, a rotary blade and the like. According to the molding method using a rotating porous die, a cylindrical granulated product having a diameter of about 3 mm and a length of about 2 to 7 mm is produced.
実施例１〜５
脂肪酸類と脂肪酸エステルとして、それぞれステアリン酸とグリセリン脂肪酸エステル（いずれも試薬）を選び、石灰窒素を含む肥料と尿素と共に表１に示す割合で混合した。この混合原料を８５℃で予備加熱した後、押出成形（回転多孔ダイス式成型機：不二パウダル社製「ディスクペレッタＦ−５型」）して粒状肥料（直径約３ｍｍ、長さ２〜７ｍｍ程度の円柱状）を製造した。
Examples 1-5
As fatty acids and fatty acid esters, stearic acid and glycerin fatty acid ester (both reagents) were selected and mixed together with a fertilizer containing lime nitrogen and urea at a ratio shown in Table 1. This mixed raw material is preheated at 85 ° C., and then extruded (rotary perforated die molding machine: “Disc Pelletta F-5” manufactured by Fuji Powder Co., Ltd.) to give a granular fertilizer (diameter of about 3 mm, length of 2 to 2). A cylindrical shape of about 7 mm) was manufactured.
実施例６〜１４
脂肪酸類と脂肪酸エステルを表２に示すように種々変えたこと以外は、実施例１と同様にして造粒した。
Examples 6-14
Granulation was carried out in the same manner as in Example 1 except that the fatty acids and fatty acid esters were variously changed as shown in Table 2.
比較例１〜６
混合原料の配合割合を表３に示す要に種々変量したこと以外は、実施例１と同様にして造粒した。
Comparative Examples 1-6
Granulation was performed in the same manner as in Example 1 except that the blending ratio of the mixed raw material was variously changed as shown in Table 3.
比較例７，８
滑剤として、表４、５に示すように、脂肪酸類の群の中から選んだ２種類（比較例７）、又は脂肪酸エステルの群の中から選んだ２種類（比較例８）を用いたこと以外は、実施例１と同様にして造粒した。なお、比較例８では混合原料の配合割合も変えた。
Comparative Examples 7 and 8
As shown in Tables 4 and 5, two types of lubricants selected from the group of fatty acids (Comparative Example 7) or two types selected from the group of fatty acid esters (Comparative Example 8) were used. Except for the above, granulation was performed in the same manner as in Example 1. In Comparative Example 8, the blending ratio of the mixed raw material was also changed.
上記実施例、比較例において、混合原料（造粒原料）の輸送性の良否を示すホッパー内残存状況を肉眼で観察し、また予備加熱の所要時間を測定した。更には、造粒時の造粒機内の原料固着状況を肉眼観察し、造粒物の有効成分を測定した。これらの結果を表６に示す。 In the above-mentioned Examples and Comparative Examples, the remaining state in the hopper showing the transportability of the mixed raw material (granulated raw material) was observed with the naked eye, and the time required for preheating was measured. Furthermore, the state of raw material fixation in the granulator during granulation was observed with the naked eye, and the active ingredients of the granulated product were measured. These results are shown in Table 6.
本発明の実施例によれば、比較例に比べ、輸送性の向上と予備加熱の所要時間短縮が可能となった。また、滑剤の使用量を低減することができた。脂肪酸類／脂肪酸エステルの質量比を２．０とした実施例５では、実施例１よりも予備加熱所要時間が長くなったが、それでも比較例よりも短くして造粒することができた。 According to the Example of this invention, compared with the comparative example, the improvement of transportability and the shortening of the time required for preheating were attained. In addition, the amount of lubricant used could be reduced. In Example 5 in which the mass ratio of fatty acids / fatty acid ester was 2.0, the time required for preheating was longer than in Example 1, but it was still possible to perform granulation with a shorter time than in Comparative Example.
これに対し、滑剤の使用量を多くした比較例１では、加圧抵抗が減少しすぎ、また少なくした比較例２では抵抗が増加しすぎ、いずれの場合も造粒不可であった。 On the other hand, in Comparative Example 1 in which the amount of the lubricant used was increased, the pressure resistance was excessively decreased, and in Comparative Example 2 in which the amount was decreased, the resistance was excessively increased. In either case, granulation was impossible.
脂肪酸類のみを滑剤とした場合、その使用量を１質量部とした比較例３では加圧抵抗が増加しすぎて造粒機内で固着し、造粒可能なだけ増量すると（比較例４）、予備加熱時間が著しく長くなった。また、脂肪酸エステルのみを滑剤とした場合、その使用量を１０質量部とした比較例５では造粒機内で造粒原料が固着し、造粒可能なだけ増量すると（比較例６）、造粒原料がホッパー内に残し輸送性が悪化した。更には、脂肪酸類同士の混合（比較例７）や、脂肪酸エステル類同士の混合（比較例８）では、輸送性の向上と予備加熱所要時間短縮の効果を同時に達成することはできなかった。 When only fatty acids are used as a lubricant, in Comparative Example 3 in which the amount used is 1 part by mass, the pressure resistance increases too much and is fixed in the granulator, and the amount is increased as much as possible (Comparative Example 4). The preheating time was significantly increased. Moreover, when only fatty acid ester is used as a lubricant, in Comparative Example 5 in which the amount used is 10 parts by mass, the granulation raw material is fixed in the granulator and the amount is increased as much as possible (Comparative Example 6). The raw material remained in the hopper and the transportability deteriorated. Furthermore, the mixing of fatty acids (Comparative Example 7) and the mixing of fatty acid esters (Comparative Example 8) could not simultaneously achieve the effects of improving transportability and shortening the required preheating time.
配管やホッパー内での原料残存が少なく、しかも予備加熱時間を短縮することができ、また尿素バインダーの使用量を低減できる石灰窒素質粒状肥料の製造方法が提供される。 There is provided a method for producing lime-nitrogenous granular fertilizer that can reduce the amount of raw materials remaining in piping and hopper, can shorten the preheating time, and can reduce the amount of urea binder used.
