Description
本発明は、食品製造加工設備用の洗浄剤組成物に関する。 The present invention relates to a detergent composition for food production processing equipment.
飲料、加工食品等の食品生産量は年々増加の一途をたどり、品質も多様化され、これに伴って衛生上の品質管理も厳しさを増している。特に、品種の多様化により、製造時に品種を変更する機会も多くなり、この結果、食品の製造設備の頻繁な洗浄を余儀なくされている。 The production volume of beverages, processed foods, etc. has been increasing year by year, the quality has been diversified, and the hygiene quality control has become more severe. In particular, due to the diversification of varieties, there are many opportunities to change the varieties at the time of manufacture, and as a result, frequent cleaning of food production facilities is required.
これら製造設備の洗浄に際し、従来では製造設備を分解した後、得られた部品を洗浄液に浸漬し、ブラシ等によるこすり洗浄が行われていた。 In cleaning these manufacturing facilities, conventionally, after disassembling the manufacturing facilities, the obtained parts were immersed in a cleaning solution and rubbed with a brush or the like.
しかし、近年、製造設備の大型化や、洗浄頻度の増加に伴い、上述のような製造設備の分解によるこすり洗浄では洗浄が困難となり、これに代わって、製造設備内に洗浄液を循環させる循環洗浄方式、タンク等の広い面積を有する表面に洗浄液をスプレーにより吹き付けて付着している汚れを洗浄除去する定置洗浄方式（ＣＩＰ）等が行われている。 However, in recent years, with the increase in the size of manufacturing equipment and the increase in the frequency of cleaning, it has become difficult to perform scrubbing by disassembling the manufacturing equipment as described above. Instead, circulating cleaning that circulates cleaning liquid in the manufacturing equipment. A stationary cleaning method (CIP) for cleaning and removing dirt adhered by spraying a cleaning liquid on a surface having a large area such as a tank or the like is performed.
従来提案されている食品製造設備等の洗浄剤として、例えば、特許文献１には、スケールや乳石の除去を目的とした、硝酸尿素、アミン系腐食抑制剤、ベンゾトリアゾール誘導体を含有するスケール除去剤組成物が、特許文献２には、ビール醸造汚れの洗浄を目的として、リン酸、アミンオキサイド、両性界面活性剤、非イオン界面活性剤を含有する硬表面用酸性洗浄剤組成物が、特許文献３には、ビール醸造汚れの洗浄を目的として、リン酸、有機酸、界面活性剤を含有するビール醸造設備用酸性洗浄剤が、特許文献４には、有機系食品汚れの洗浄を目的に、リン酸、有機カルボン酸、エーテル系又はアルコール系溶剤、キレート剤、エーテルアミンを含有する有機系汚染に対して使用する為の抗黴生物酸クリーナーが、特許文献５には、タンパク質の除去を目的として、リン酸等の無機酸、乳化剤、キレート剤、界面活性剤を含有するタンパク質物質を除去するのに適当な組成物が開示されている。 As a cleaning agent for food production equipment and the like that has been proposed in the past, for example, Patent Document 1 discloses a scale removal containing urea nitrate, an amine-based corrosion inhibitor, and a benzotriazole derivative for the purpose of removing scale and milkstone. Patent Document 2 discloses a hard surface acidic detergent composition containing phosphoric acid, amine oxide, amphoteric surfactant, and nonionic surfactant for the purpose of cleaning beer brewing stains. Reference 3 discloses an acidic detergent for beer brewing equipment containing phosphoric acid, an organic acid, and a surfactant for the purpose of cleaning beer brewing stains. Patent Document 4 discloses the cleaning of organic food stains. Patent Document 5 discloses an antifungal acid cleaner for use against organic contamination containing phosphoric acid, organic carboxylic acid, ether or alcohol solvent, chelating agent, ether amine. The purpose of removal of protein, inorganic acids such as phosphoric acid, an emulsifier, a chelating agent, a suitable composition for removal of protein material containing a surface active agent is disclosed.
一方、食品工業における製造設備をアルカリ系で洗浄する技術として、例えば特許文献６には、食品工場での汚れの容易な除去を目的として、アルカリ、特定キレート剤、グリコールエーテル系溶剤、界面活性剤を含有する食品工業用液体洗浄剤組成物が、特許文献７には、陶磁器等に付着した有機質汚れの除去を目的として、アルカリ、特定キレート剤、界面活性剤を含有するアルカリ洗浄剤が開示されている。
しかしながら、まず特許文献１〜５は、いずれも酸性下での洗浄である為、殺菌プレートにおける熱変性したタンパク汚れ等に関しては、充分な洗浄効果が得られない場合がある。 However, since Patent Documents 1 to 5 are all washed under an acidic condition, a sufficient washing effect may not be obtained with respect to heat-denatured protein stains on the sterilization plate.
また、従来のアルカリ系で洗浄する技術では、ある程度の洗浄効果こそ期待できるものの、食品由来の汚れを短時間で且つ容易に洗浄する場合においては十分な洗浄効果を発現し難い場合があるといった問題がある。 In addition, the conventional alkaline cleaning technology can be expected to have a certain level of cleaning effect, but it may be difficult to achieve a sufficient cleaning effect in the case where food-derived stains are easily cleaned in a short time. There is.

洗浄方法の具体例としては、ＣＩＰ洗浄が挙げられる。食品工場、飲料工場等において、生産品種切り替え時や操業終了時等にその製造設備や機器類の洗浄を行っているが、配管、タンク等の取り外し洗浄が困難な箇所に関してはＣＩＰ洗浄（定置洗浄）を行っている。このＣＩＰ洗浄とは、Cleaning in placeの頭文字を取った言葉で、装置を分解する事なく洗浄剤を流す事により洗浄する方法である。該洗浄液は、６０〜９８℃の範囲で、ＣＩＰ洗浄における被洗浄物である配管内、及び各種機器類と接触するように循環、あるいはタンク等の広い面積を有する表面においては、該洗浄液をスプレーにより吹き付けて、付着している汚れを洗浄する事が好ましい。該洗浄液は、この温度範囲で前記のｐＨを満たすことが好ましい。又、配管内を流れる洗浄液の流速としては、０．５〜５ｍ／秒、更に１〜３ｍ／秒が好ましい。 A specific example of the cleaning method is CIP cleaning. In food factories, beverage factories, etc., production facilities and equipment are cleaned when production varieties are switched or when operations are completed. CIP cleaning (fixed cleaning) is used for places where piping and tanks are difficult to remove and clean. )It is carried out. This CIP cleaning is an acronym for “Cleaning in place”, and is a method of cleaning by flowing a cleaning agent without disassembling the apparatus. The cleaning liquid is sprayed in a range of 60 to 98 ° C. in a pipe which is an object to be cleaned in CIP cleaning, or on a surface having a large area such as a tank so as to come into contact with various devices. It is preferable to clean the adhered dirt by spraying. The cleaning liquid preferably satisfies the above pH within this temperature range. Further, the flow rate of the cleaning liquid flowing in the pipe is preferably 0.5 to 5 m / sec, and more preferably 1 to 3 m / sec.

The cleaning liquid obtained from the composition of the present invention is mainly used during alkali cleaning in this step. It is preferable to be done.
牛乳の製造工程では、加熱殺菌等の工程において、プレート式熱交換機により加熱、冷却が行われるが、このようなプレートには、タンパク質汚れや熱変性タンパク汚れが付着する。牛乳の製造ラインもＣＩＰ洗浄が可能であるが、プレートに付着したタンパク質汚れや熱変性タンパク汚れは強固であり、ＣＩＰ洗浄で十分に除去するには長時間の処理が要求される。しかし、本発明の洗浄剤組成物によれば、通常のＣＩＰ洗浄により、牛乳の製造設備の十分な洗浄を行うことができる。 In the milk production process, heating and cooling are performed by a plate heat exchanger in a process such as heat sterilization, and protein stains and heat-denatured protein stains adhere to such plates. The milk production line can also be CIP cleaned, but protein stains and heat-denatured protein stains adhering to the plate are strong, and a long time treatment is required to sufficiently remove them by CIP cleaning. However, according to the cleaning composition of the present invention, it is possible to sufficiently clean milk production equipment by ordinary CIP cleaning.
