【発明の属する技術分野】
本発明はビール工場やジュース等の飲料工場、牛乳工場、冷凍およびレトルト食品、調味料やマヨネーズ等の食品加工工場等の各種食品製造工場における被洗浄物、例えば、タンク、配管等の設備、充填機、殺菌機、熱処理機等の各種機器、ビン、コンテナ、クレイト、樽等の各種容器類等の洗浄に用いられる抑泡性アルカリ洗浄剤の安定化処理方法に係り、特に過酷な保存温度条件下、例えば、気温が−５℃以下に降下する寒冷地、あるいは４０℃以上に上昇する夏場等の条件下でも沈殿、分離、浮遊物の発生等の不都合が生ぜず、常に透明、懸濁、乳化等の均一な状態を保持して充分な安定性を得る抑泡性アルカリ洗浄剤の安定化処理方法に関する。
【０００２】
【従来の技術】
ビール工場、飲料工場、牛乳工場、その他の各種食品製造工場におけるタンク、配管等の各種設備、充填機、殺菌機、熱処理機等の各種機器、ビン、コンテナ、クレイト、樽等の各種容器類は機械式自動洗浄、とりわけ定置洗浄（ＣＩＰ）によりアルカリ洗浄剤を用いて定期的に洗浄を受けている。
【０００３】
このアルカリ洗浄剤は通常、洗浄に際して適当な濃度、例えば１〜１０％の濃度に水で稀釈し、ポンプで送液して循環洗浄に供される。このとき、洗浄稀釈液には食品中の蛋白質、油脂、炭水化物等が混入され、これが発泡の原因となる。
【０００４】
そして、洗浄の後、この稀釈洗浄液は回収タンクに戻され、再使用される。この回収された洗浄稀釈液にも上述と同様、食品中の蛋白質、油脂、炭水化物等が混入されており、これが再使用の際に発泡の原因となる。
【０００５】
上述の発泡が起こると、洗浄稀釈液と被洗浄面との接触が妨げられて洗浄不良を起こし、また、タンク中でオーバーフローを起こし、さらにはポンプ中でエアレーションを起こして機械的な支障を来す。
【０００６】
このような問題を解決するために、従来では、アルカリ洗浄剤に抑泡性を呈する非イオン界面活性剤（例えばポリオキシアルキレンエーテル）を配合して対応している。しかし、非イオン界面活性剤はアルカリ洗浄剤に均一に配合されず、分離や、沈殿や、かたまり等を起こしてしまい、安定な配合が困難であった。
【０００７】
【発明が解決すべき課題】
非イオン界面活性剤をアルカリ洗浄剤中に均質に配合する手段として、従来、特定のアニオン界面活性剤を併用して乳化させたり、界面活性剤とハイドロトロープ剤を組み合わせたり、等が試みられているが、それでも４０℃以上の高温や、−５℃以下の低温等、過酷な保存条件下では充分な安定性が達成され得なかった。
【０００８】
そこで、本発明の目的は食品製造設備の洗浄に用いられる抑泡性アルカリ洗浄剤の安定化処理に際し、特に、４０℃以上の高温や−５℃以下の低温等、過酷な保存温度条件下でも充分な安定性を確保し、上述の従来技術に存する欠点を改良した抑泡性アルカリ洗浄剤の安定化処理方法を提供することにある。
【０００９】
【課題を解決するための手段】
上述の目的を達成するため、本発明の安定化処理方法によれば、苛性アルカリおよび／または有機キレート剤を主成分としたアルカリ洗浄剤に抑泡性の非イオン界面活性剤を含有せしめ、主として食品製造設備の洗浄に用いられる抑泡性アルカリ洗浄剤において、さらに、アルキルポリグリコシド、アルキル燐酸エステルまたはそのアルカリ塩、およびクメンスルホン酸またはそのアルカリ塩の三成分を前記洗浄剤１００重量部に対して、三成分の合計量が１重量パーセント以上、および三成分の各成分がそれぞれ０．３重量パーセント以上の割合で配合し、前記洗浄剤を均一に保持して安定化することを特徴とする。
【００１０】
【発明の実施の態様】
以下、本発明を具体的に詳述する。
【００１１】
本発明は苛性アルカリおよび／または有機キレート剤を主成分としたアルカリ洗浄剤に抑泡性の非イオン界面活性剤（ポリオキシアルキレンエーテル等）を含有せしめ、主として食品製造設備の洗浄に用いられる抑泡性アルカリ洗浄剤の安定化処理に係わる。
【００１２】
ここで、洗浄に付される食品製造設備はタンク、配管等の各種設備、充填機、殺菌機、熱処理機等の各種機器、ビン、コンテナ、クレイト、樽等の各種容器等である。これら各種食品製造設備は機械式自動洗浄、特に定置洗浄（ＣＩＰ）により洗浄を受ける。
【００１３】
本発明の特徴は上述の苛性アルカリおよび／または有機キレート剤を主成分としたアルカリ洗浄剤に抑泡性の非イオン界面活性剤（ポリオキシアルキレンエーテル等）を含有せしめてなる抑泡性アルカリ洗浄剤に、さらにアルキルポリグリコシド、アルキル燐酸エステルまたはそのアルカリ塩、およびクメンスルホン酸またはそのアルカリ塩の三成分を配合して前記抑泡性アルカリ洗浄剤を安定化処理することに存する。
【００１４】
ここで、「安定化」とは抑泡性アルカリ洗浄剤が過酷な保存温度条件下、例えば気温が−５℃以下に降下する寒冷地、あるいは４０℃以上に上昇する夏場等の条件下でも、洗浄剤が沈殿を生ぜず、分離を起こさず、あるいは浮遊物を発生せず、常に透明、懸濁、乳化等、均一に保持される状態を言う。
【００１５】
本発明に用いられる苛性アルカリとしては、苛性ソーダ、苛性カリ等であり、また有機キレート剤としては、例えば、エチレンジアミン四酢酸、グルコン酸、グルタミン酸二酢酸、アスパラギン酸二酢酸、ニトリロ三酢酸、２−ヒドロキシエチルイミノ二酢酸、メチルグリシン二酢酸およびこれらのアルカリ金属塩である。このアルカリ金属塩としては、ナトリウム、カリウム等が挙げられる。また、本発明に用いられる非イオン界面活性剤としては、ポリオキシアルキレンエーテル等が挙げられる。
【００１６】
本発明では、これら苛性アルカリおよび有機キレート剤はそれぞれ別々に主成分とすることもでき、あるいは両者を併せて主成分とすることもできる。これらの配合量は例えば、苛性アルカリを主成分とする場合には、有機キレート剤の含有量が０．１〜２５重量％であり、有機キレート剤を主成分とする場合には苛性アルカリの含有量が０．１〜２５重量％であり、両者を主成分とする場合には、これらの合計量が０．２〜７５重量％であり、残りが例えば燐酸塩、珪酸塩およびポリカルボン酸塩等である。
【００１７】
本発明に用いられるアルキルポリグリコシドはアルキル基の炭素数Ｃ１８以下の非イオン界面活性剤であって、具体的には、例えばデシルポリグリコシド、オクチルポリグリコシド、ヘキシルポリグリコシド等である。また、アルキル燐酸エステルまたはそのアルカリ塩はアルキル基の炭素数Ｃ：２０以下、エチレンオキサイドのモル数（ｎ）：０モルないし１０以下の正数モル、アルカリ塩がナトリウム、カリウム等のアルカリ金属のアニオン界面活性剤であって、具体的にはポリオキシエチレン（ｎ：１０）ヘキシルエーテル燐酸ナトリウム、ポリオキシエチレン（ｎ：４）オクチルエーテル燐酸カリウム、ポリオキシエチレン（ｎ：２）オレイルエーテル燐酸ナトリウム等である。さらに、クメンスルホン酸またはそのアルカリ塩はこのアルカリ塩がナトリウム、カリウム等のアルカリ金属であって、具体的にはクメンスルホン酸、クメンスルホン酸ナトリウム、クメンスルホン酸カリウム等である。
【００１８】
これら三成分は本発明では、上述の抑泡性アルカリ洗浄剤１００重量部に対して、三成分の合計量が１重量部以上、好ましくは２重量部以上、さらに好ましくは２〜１０重量部の割合で配合される。また、これら三成分の各々は少なくとも０．３重量％配合することが必要であるが、各成分間の配合比率は任意であり、好ましくはほぼ同量ずつ、さらに好ましくは三成分がそれぞれ１〜２重量部の割合で配合される。
【００１９】
上述の本発明にかかる抑泡性アルカリ洗浄剤は食品製造設備の洗浄に際して、水で１〜１０％程度に稀釈し、得られた稀釈洗浄液をポンプで送液して循環洗浄に供され、洗浄後もポンプで送液して再使用され、あるいは回収タンクに戻されて再使用される。
【００２０】

[0010]
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Hereinafter, the present invention will be described in detail.
[0011]
According to the present invention, an alkaline cleaning agent containing a caustic alkali and / or an organic chelating agent as a main component contains a foam-suppressing nonionic surfactant (such as polyoxyalkylene ether), and is used mainly for cleaning food production equipment. It is related to the stabilization treatment of foaming alkali detergent.
[0012]
Here, the food manufacturing equipment to be washed includes various equipment such as tanks and pipes, various equipment such as filling machines, sterilizers, and heat treatment machines, and various containers such as bottles, containers, clays, and barrels. These various food manufacturing facilities are cleaned by mechanical automatic cleaning, especially cleaning in place (CIP).
[0013]
A feature of the present invention is a foam-suppressing alkali cleaning agent obtained by adding a foam-suppressing nonionic surfactant (such as polyoxyalkylene ether) to the above-described alkali cleaning agent containing a caustic alkali and / or an organic chelating agent as a main component. The composition further comprises three components of an alkyl polyglycoside, an alkyl phosphate or an alkali salt thereof, and cumenesulfonic acid or an alkali salt thereof to stabilize the foam-suppressing alkali detergent.
[0014]
Here, "stabilization" means that the foam-suppressing alkaline detergent is under severe storage temperature conditions, for example, in a cold region where the temperature drops to -5C or less, or even in a summer condition where the temperature rises to 40C or more. This refers to a state in which the detergent is kept uniformly, such as transparent, suspended, or emulsified, without generating precipitation, causing separation, or generating suspended matter.
[0015]
Examples of the caustic alkali used in the present invention include caustic soda and caustic potash, and examples of the organic chelating agent include ethylenediaminetetraacetic acid, gluconic acid, glutamic diacetate, aspartic diacetate, nitrilotriacetic acid, and 2-hydroxyethyl. Iminodiacetic acid, methylglycinediacetate and their alkali metal salts. Examples of the alkali metal salt include sodium and potassium. Further, examples of the nonionic surfactant used in the present invention include polyoxyalkylene ether and the like.
[0016]
In the present invention, these caustic alkalis and organic chelating agents can be used separately as main components, or both can be used as main components together. The content of these components is, for example, when the caustic alkali is the main component, the content of the organic chelating agent is 0.1 to 25% by weight, and when the caustic alkali is the main component, the content of the caustic alkali is When the amount is 0.1 to 25% by weight, and when both are the main components, the total amount thereof is 0.2 to 75% by weight, and the balance is, for example, phosphate, silicate and polycarboxylate. And so on.
[0017]
The alkyl polyglycoside used in the present invention is a nonionic surfactant having a carbon number of C18 or less in the alkyl group, and specific examples include decyl polyglycoside, octyl polyglycoside, and hexyl polyglycoside. Alkyl phosphates or alkali salts thereof include a carbon number C: 20 or less of an alkyl group, a mole number (n) of ethylene oxide: a positive number of 0 to 10 or less, and an alkali salt of an alkali metal such as sodium or potassium. Anionic surfactants, specifically, sodium polyoxyethylene (n: 10) hexyl ether phosphate, potassium polyoxyethylene (n: 4) octyl ether phosphate, sodium polyoxyethylene (n: 2) oleyl ether phosphate And so on. Further, the cumenesulfonic acid or an alkali salt thereof is an alkali metal such as sodium or potassium, and specifically, cumenesulfonic acid, sodium cumenesulfonic acid, potassium cumenesulfonic acid or the like.
[0018]
In the present invention, these three components are used in an amount of 1 part by weight or more, preferably 2 parts by weight or more, more preferably 2 to 10 parts by weight, based on 100 parts by weight of the above-mentioned foam-suppressing alkali detergent. It is blended in a ratio. It is necessary that at least 0.3% by weight of each of these three components is blended. However, the blending ratio between the components is arbitrary, preferably approximately the same amount, more preferably 1 to 3 each. It is blended at a ratio of 2 parts by weight.
[0019]
The above-mentioned foam-suppressing alkaline detergent according to the present invention is diluted with water to about 1 to 10% at the time of cleaning food production equipment, and the resulting diluted cleaning solution is sent by a pump to be subjected to circulating cleaning, followed by cleaning. After that, the liquid is pumped and reused, or returned to the collection tank and reused.
[0020]
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited to these examples.
[0021]
[Example 1]
Each sample No. shown in Table 1. 1-12 were prepared. Each of these samples was left for 30 days while being exposed to the outside air at each temperature shown in Table 1.
[0022]
After a lapse of 30 days, the liquid state of each sample was visually observed, and the results are shown in Table 1. In Table 1, ○ indicates stable while maintaining a uniform state such as transparency, suspension, emulsification, etc., や indicates slightly stable, and × indicates precipitation, separation, and generation of suspended matter, respectively.
[0023]
[Table 1]
As is clear from Table 1, the sample No. according to the present invention. 1 to 6 are all ○ at −5 to 40 ° C., indicating that the detergent is stabilized. On the other hand, it can be seen that the other samples are unstable at high and low temperatures. In particular, it can be seen from the comparative example that even if one of the components is 0.3% or less, the stability is poor.
[0025]
【The invention's effect】
As described above, in the present invention, specific three components are combined in addition to the defoaming alkaline cleaning agent. Therefore, even in a severe temperature atmosphere of -5 ° C or lower and 40 ° C or higher, sedimentation and generation of separated floating substances are caused. This is a practically useful stabilization method that does not cause inconveniences such as the above, and always maintains a uniform state such as transparency, suspension, and emulsification to obtain sufficient stability.
