Description
本発明は、植物油粕の製造方法に関するものである。 The present invention relates to a method for producing vegetable oil meal.
植物油の製造工程における副産物として得られる植物油粕は、飼料や肥料、あるいは食品原料などの用途に使用されている。 Vegetable oil cake obtained as a by-product in the production process of vegetable oil is used for applications such as feed, fertilizer, or food materials.
この植物油粕の製造方法としては、油分を溶剤で抽出した抽出粕に対して脱溶剤処理を行なう工程を経て製造する方法が一般的である（例えば、特許文献１参照）。脱溶剤処理は、加熱処理を伴うので、脱溶剤処理後には、ミールクーラー等を用いて冷却することが行われている。ミールクーラーは、風冷で行われるが、風に乗って油粕中の微粉末が除去される。 As a method for producing this vegetable oil cake, a method of producing the vegetable oil cake through a process of removing the solvent from the extracted meal obtained by extracting the oil with a solvent is generally used (see, for example, Patent Document 1). Since the solvent removal treatment involves heat treatment, cooling is performed using a meal cooler or the like after the solvent removal treatment. The meal cooler is air-cooled, but the fine powder in the oil bottle is removed by riding on the wind.
これら植物油粕の製造工程で発生する微粉末は、蛋白質含量などは植物油粕の製品と遜色ないため、有効利用が求められていた。 The fine powder generated in the production process of these vegetable oil cakes has been required to be effectively used because the protein content is not inferior to that of vegetable oil cake products.
しかし、これらの微粉末は、植物油粕の製造工程から、いったん排出されるため、そのまま植物油粕に添加すると衛生性の問題が発生する。そのため、加熱殺菌等の追加の工程を行わない限り、飼料、食品原料用途として用いることはできなかったため、その多くは廃棄していた。さらに、植物油粕にそのまま植物油粕の製造工程で発生した微粉末を添加した場合、その後の飼料製造又は大豆蛋白等の食品原料、あるいは食品を製造する過程で、微粉末による配管や篩等での詰り、汚染等が発生し、製造工程における作業効率が低下する問題があった。 However, since these fine powders are once discharged from the production process of vegetable oil cake, if added to the vegetable oil cake as it is, sanitary problems occur. Therefore, unless additional steps such as heat sterilization are performed, they cannot be used as feed or food raw materials, and many of them have been discarded. Furthermore, when the fine powder generated in the production process of the vegetable oil cake is added to the vegetable oil cake as it is, in the course of the subsequent feed production or food raw materials such as soy protein, or in the process of producing the food, There is a problem that clogging, contamination, and the like occur and work efficiency in the manufacturing process decreases.
従って、本発明の目的は、植物油粕の製造工程から発生する微粉末を、再度植物油粕の製造工程で添加し、収率が高く、品質が従来と同等である植物油粕の製造方法を提供することである。 Accordingly, an object of the present invention is to provide a method for producing a vegetable oil cake in which the fine powder generated from the vegetable oil cake production process is added again in the vegetable oil cake production process, and the yield is high and the quality is equivalent to the conventional one. That is.

〔植物油粕の製造方法〕
本発明の実施の形態に係る植物油粕の製造方法は、溶剤抽出工程より後の製造工程で発生する油粕の微粉末を、溶剤抽出工程以前の工程で抽出原料に添加する工程を含む。以下、各工程を順に説明する。
[Method for producing vegetable oil cake]
The manufacturing method of the vegetable oil cake which concerns on embodiment of this invention includes the process of adding the fine powder of the oil cake generated in the manufacturing process after a solvent extraction process to an extraction raw material in the process before a solvent extraction process. Hereinafter, each process is demonstrated in order.
精選、粗砕、乾燥、加熱、圧扁などの前処理を経た油糧原料（抽出原料）を溶剤抽出工程で油分を植物油粕より分離する。溶剤は、ヘキサン、アセトン、エタノール等の有機溶媒を用いて行うことができるが、国内では一般的にヘキサンが用いられている。油糧原料（抽出原料）は、特に限定されるものではないが、大豆、菜種、コーン、綿実、紅花、ヒマワリ、落花生、ゴマ、アマニ、米ぬか、グレープシードなどを用いることができ、中でも大豆又は菜種を使用することが好ましい。食品用途の衛生性の点から特に好ましくは大豆である。なお、菜種、ゴマ、アマニ等の油分の多い油糧原料は、通常、抽出原料中の油分を低下させるために、溶剤抽出工程の前に圧搾工程を設けることが行われており、本発明では圧搾工程を経た圧搾粕を抽出原料に用いることができる。 The oily material (extracted raw material) that has undergone pretreatments such as fine selection, coarse crushing, drying, heating, and compaction is separated from the vegetable oil cake in a solvent extraction process. The solvent can be used using an organic solvent such as hexane, acetone, ethanol, etc., but hexane is generally used in Japan. Oil raw materials (extracted raw materials) are not particularly limited, but soybeans, rapeseed, corn, cottonseed, safflowers, sunflowers, peanuts, sesame seeds, flaxseed, rice bran, grape seeds, etc. can be used. Or it is preferable to use rapeseed. Soybean is particularly preferred from the viewpoint of hygiene for food use. In addition, oily raw materials with high oil content such as rapeseed, sesame and flax are usually provided with a pressing step before the solvent extraction step in order to reduce the oil content in the extracted raw material. The pressed rice cake that has undergone the pressing step can be used as the extraction raw material.
溶剤抽出工程で発生する油粕は、溶剤を含有しているため、加熱して脱溶剤を行う。脱溶剤工程は、加水・加熱及び／もしくは加熱で行われ、油粕の脱溶剤のほか、蛋白変性も起こる。脱溶剤工程は、例えば、デソルベンタイザー・トースターと呼ばれる装置を用いることができる。デソルベンタイザー・トースター内部では、脱溶剤工程は、加水・加熱条件下で行なわれ、加熱により水蒸気雰囲気とした塔内（処理装置内）で行なわれることが好ましい。湿度は、３０〜１００％が好ましく、５０〜１００％がより好ましく、８０〜１００％がさらに好ましい。温度は、５０〜１３０℃が好ましく、８０〜１２０℃がより好ましく、９０〜１１０℃がさらに好ましい。 Since the oil cake generated in the solvent extraction step contains a solvent, the solvent is removed by heating. The solvent removal step is carried out by hydration, heating and / or heating, and protein denaturation occurs in addition to the removal of the oil cake. For the solvent removal step, for example, an apparatus called a desolventizer toaster can be used. In the desolventizer / toaster, the solvent removal step is preferably carried out under water and heating conditions, and is preferably carried out in a tower (within the treatment apparatus) that is made into a steam atmosphere by heating. The humidity is preferably 30 to 100%, more preferably 50 to 100%, and still more preferably 80 to 100%. The temperature is preferably 50 to 130 ° C, more preferably 80 to 120 ° C, and still more preferably 90 to 110 ° C.
なお、植物油粕の製品の油分等の品質を調整するために、油脂や油脂の精製工程で発生する油滓等を植物油粕に添加することができるが、好ましくは、脱溶剤工程で添加することが好ましい。 In addition, in order to adjust the quality of the oil content of vegetable oil cake products, oil and fats generated in the oil and fat refining process can be added to the vegetable oil meal, but preferably added in the solvent removal process. Is preferred.
脱溶剤工程を経た油粕は、水分を含むため、水分が約１５％以下になるように乾燥する。乾燥工程は、例えばロータリードライヤーを用いる。乾燥工程中の油粕の品温は７０〜１００℃であり、好ましくは８０〜９０℃である。 The oil cake that has undergone the solvent removal step contains moisture, and thus is dried so that the moisture becomes about 15% or less. In the drying step, for example, a rotary dryer is used. The temperature of the oil cake during the drying process is 70 to 100 ° C, preferably 80 to 90 ° C.
乾燥工程を経た油粕は、さらに冷却を行う。冷却工程では、例えば、気流中で油粕を落下、あるいは、油粕に気体を吹き付ける等で行うことができる。冷却工程を経た油粕は、整粒工程で粒子径を調整して製品となる。 The oil cake that has undergone the drying process is further cooled. In the cooling step, for example, the oil can be dropped in an air stream, or gas can be blown onto the oil can. The oil cake that has undergone the cooling process becomes a product by adjusting the particle diameter in the granulation process.
脱溶剤工程、乾燥工程、冷却工程、整粒工程の各工程では、各処理装置から排出される気体の出口に集塵機を設けることで、微粉末を集めることができる。特にサイクロン集塵機が微粉末による目詰まり等を起こさない点で好ましい。また、油粕の乾燥が進んだ冷却工程以降の工程が特に、微粉末が発生しやすい。さらに、油粕に強い気流を接触させる冷却工程で微粉末を収集することが容易である。 In each process of a solvent removal process, a drying process, a cooling process, and a granulation process, a fine powder can be collected by providing a dust collector in the exit of the gas discharged | emitted from each processing apparatus. The cyclone dust collector is particularly preferable in that it does not cause clogging due to fine powder. In addition, fine powder is likely to be generated particularly in the steps after the cooling step in which the drying of the oil cake has progressed. Furthermore, it is easy to collect fine powder in a cooling process in which a strong air stream is brought into contact with the oil bottle.
集められた微粉末は、抽出工程以前の工程で添加することができる。添加工程は、特に抽出工程以前であれば、植物油粕の衛生上問題ない品質となり、また、微粉末を添加することで製品中の微粉末量が増えることもない。 The collected fine powder can be added before the extraction step. If the addition process is prior to the extraction process, the quality of the vegetable oil cake is not problematic in terms of hygiene, and addition of the fine powder does not increase the amount of fine powder in the product.
油粕の微粉末は、４８メッシュの篩（タイラー）にかけて得られる篩下の画分が多い。例えば、４８メッシュの篩（タイラー）にかけて得られる篩下の画分は５０質量％以上になることが多く、特に好ましくは６０質量％以上である。 The fine powder of oil cake has a large fraction under the sieve obtained by passing it through a 48 mesh sieve (Tyler). For example, the fraction under the sieve obtained through a 48 mesh sieve (Tyler) is often 50% by mass or more, and particularly preferably 60% by mass or more.

[Reference Example 1]
The rapeseed extraction raw material (pressed lees) was hexane extracted with an extractor to obtain rapeseed oil lees (extracted lees). The rapeseed oil cake was desolvated (desolventizer toaster, steam blown, about 100 ° C.), and the water content in the oil cake was reduced to 13% with a rotary dryer. Thereafter, the rapeseed oil cake was cooled to room temperature with a meal cooler (wind cooling). The rapeseed oil cake was sized using a particle sizer (hammer mill and sieve: Tyler 12 mesh) to obtain an oil cake (oil cake A). Fine powder was collected with a cyclone type dust collector at each airflow outlet of the desolventizer toaster, rotary dryer, meal cooler, and granulator. The composition of each fine powder was a total nitrogen amount of 5.5-6.1% and a crude protein content of 34-38%. The obtained fine powder was mixed to obtain a mixed fine powder (fine powder A). The fine powder A was 4.2% with respect to the oil cake A, of which about 80% was fine powder of a meal cooler. When fine powder A was sieved with a 48-mesh sieve (Tyler), the mass on the sieve was 35 mass%, and the mass under the sieve was 65 mass%. In addition, when salmonella inspection of oil cake A and fine powder A was performed, oil cake A was salmonella negative, but fine powder A was salmonella positive.

使用油粕を下記の大豆抽出原料に替えた以外は参考例１と同様に処理を行い、微粉末（微粉末Ｃ）を油粕（油粕Ｃ）に対して約３．５％得た。さらに実施例１と同様に大豆抽出原料に微粉末Ｃを添加し、油粕（油粕Ｄ）と微粉末（微粉末Ｄ）を得た。微粉末Ｄは、油粕Ｄに対して約３．６％であった。油粕Ｄの衛生検査を実施したところ、サルモネラ陰性であった。
[Example 2]
The treatment was performed in the same manner as in Reference Example 1 except that the used soybean cake was replaced with the following soybean extract raw material, and about 3.5% of fine powder (fine powder C) was obtained with respect to the oil cake (oil cake C). Further, fine powder C was added to the soybean extract raw material in the same manner as in Example 1 to obtain oil cake (oil cake D) and fine powder (fine powder D). The fine powder D was about 3.6% with respect to the oil cake D. When the sanitary inspection of oil cake D was conducted, it was negative for Salmonella.
以上の通り、溶剤抽出工程以前に、微粉末を添加した油粕は、衛生上問題なく、また、溶剤抽出工程以前に微粉末を添加しても、微粉末が多量に増加することがなかった。 As described above, the oil cake to which the fine powder was added before the solvent extraction step had no sanitary problem, and even if the fine powder was added before the solvent extraction step, the fine powder did not increase greatly.
