Abstract
Description
本発明は、乳飲料、果汁飲料、茶系飲料、コーヒー、ビール等の飲料および乳製品、加工食品、調味料等の飲食料品の製造ラインの生産設備を分解せずに簡単な操作で安全に自動洗浄するＣＩＰ洗浄方法（Ｃｌｅａｎｉｎｇ ｉｎ Ｐｌａｃｅ「定置洗浄」）に関するものである。 The present invention is safe by simple operation without disassembling the production equipment of milk beverages, fruit juice beverages, tea beverages, beverages such as coffee and beer, and food and beverage products such as dairy products, processed foods, and seasonings. The present invention relates to a CIP cleaning method (Cleaning in Place “fixed cleaning”).
従来から、各種の飲食料品を缶や瓶、或いはペットボトルなどの容器に充填した製品を製造するための生産設備を分解せずに簡単な操作で安全に自動洗浄するＣＩＰ洗浄が行われている。 Conventionally, CIP cleaning has been performed to automatically and safely perform cleaning with simple operation without disassembling the production equipment for manufacturing products filled with various food and drink products in containers such as cans, bottles, and PET bottles. Yes.
そして、ＣＩＰ洗浄の洗浄液や洗浄方法はそれぞれ使用する飲料などに合わせて適宜選択されるが、例えば牛乳、飲むヨーグルト、ミルク入りコーヒーのようなミルク入り飲料などの有機物だけでなく無機物をも多く含む製品についての生産設備では汚れが落ちにくいという問題があった。 The cleaning solution and cleaning method for CIP cleaning are appropriately selected according to the beverages to be used, but include not only organic substances such as milk, drinks with yogurt, milk-containing drinks such as coffee with milk, but also a lot of inorganic substances. There was a problem that dirt was difficult to remove in production facilities for products.
そこで、この種の製品を扱う生産設備について従来のＣＩＰ洗浄方法は、特開２００５−１２６５６７号公報（特許文献１）、特開２０１０−２１５７８０号公報（特許文献２）などに提示されており、例えば、製品製造が終了した後、まず水でライン中を前洗浄し、次に、アルカリ洗浄剤（水酸化ナトリウム水溶液や塩素系アルカリ洗浄剤溶液）でたんぱく質や炭水化物を溶解除去する。そして中間リンス（主に水を用いる）を行い、始めの洗浄剤が次の洗浄剤に混入するのを防ぎ、次に酸洗浄剤（硝酸水溶液が一般的、ほかに燐酸、クエン酸、マレイン酸なども溶質として使用される）が使用され、無機質の沈着物を酸洗浄剤で溶解除去して後、酸洗浄剤をリンスするのが一般的である。 Therefore, conventional CIP cleaning methods for production facilities that handle this type of product are presented in Japanese Patent Application Laid-Open No. 2005-126567 (Patent Document 1), Japanese Patent Application Laid-Open No. 2010-215780 (Patent Document 2), and the like. For example, after the production of the product is completed, the inside of the line is first prewashed with water, and then the protein and carbohydrate are dissolved and removed with an alkaline detergent (sodium hydroxide aqueous solution or chlorinated alkaline detergent solution). Then, an intermediate rinse (mainly using water) is performed to prevent the first cleaning agent from being mixed into the next cleaning agent, and then an acid cleaning agent (a nitric acid aqueous solution is generally used, as well as phosphoric acid, citric acid, maleic acid) Etc. are also used as solutes), and after the inorganic deposits are dissolved and removed with an acid cleaning agent, the acid cleaning agent is generally rinsed.
ところが、前記従来のＣＩＰ洗浄方法は、前洗浄した後、アルカリ洗浄剤で洗浄し、次に、中間リンスを行い更に酸性洗浄剤で洗浄してリンスを行うなどの必要があり、中間リンスを必要とするなど洗浄工程が多く作業が繁雑であるとともに２種類の洗浄剤を用いて洗浄することから洗浄時間も長く、更に、上下水道の使用量も多く、洗浄効果を高める必要性から洗浄液やリンス液を６０〜８０℃の高温に加温することも必要であり電気や蒸気などの多大なエネルギーの消費も生じていた。 However, in the conventional CIP cleaning method, after pre-cleaning, it is necessary to perform cleaning with an alkaline cleaning agent, and then perform an intermediate rinsing and further rinsing with an acidic cleaning agent. Since there are many cleaning processes and the work is complicated and cleaning is performed using two types of cleaning agents, the cleaning time is long, and the amount of water and sewage used is also large. It is also necessary to heat the liquid to a high temperature of 60 to 80 ° C., and consumption of enormous energy such as electricity and steam has occurred.
また、例えば界面活性剤、キレート剤、乳化剤などを加えて洗浄剤の洗浄効果の向上を図る手段が特開２００２−１０５４８９号公報（特許文献３）、特表２００２−５４０２５３号公報（特許文献４）、特表２００４−５００４７２号公報（特許文献５）などに提示されているが、これらはいずれもアルカリ洗浄液の改良にかかるものであり、その後の酸洗浄工程を含めて省力化を図るものでなく、寧ろ、高額になる。 Further, for example, means for improving the cleaning effect of a cleaning agent by adding a surfactant, a chelating agent, an emulsifier, etc. are disclosed in JP-A-2002-105489 (Patent Document 3) and JP-T-2002-540253 (Patent Document 4). ), And Japanese translations of PCT publication No. 2004-500472 (patent document 5) etc., all of which are related to the improvement of the alkaline cleaning solution, and are intended to save labor including the subsequent acid cleaning step. Rather, it is expensive.
本発明は、従来のＣＩＰ洗浄における労力、時間、エネルギー、資源の省力化を図るばかりか十分な洗浄効果を得ることが可能なＣＩＰ洗浄方法を提供することを課題とする。 It is an object of the present invention to provide a CIP cleaning method capable of saving labor, time, energy, and resources in conventional CIP cleaning and obtaining a sufficient cleaning effect.
前記課題を解決するためになされた本発明は、塩素系アルカリ洗浄剤溶液で飲食料品製造ラインのたんぱく質、炭水化物などの有機物系固着物を溶解除去し（工程（ａ））、次に、前記塩素系アルカリ洗浄剤溶液にキレート剤を添加した洗浄液で無機質の沈着物を溶解除去する（工程（ｂ））ことを特徴とする。 The present invention was made to solve the above problems by dissolving and removing organic substances such as proteins and carbohydrates in food and beverage production lines with a chlorinated alkaline detergent solution (step (a)), It is characterized by dissolving and removing inorganic deposits with a cleaning liquid obtained by adding a chelating agent to a chlorine-based alkaline cleaning agent solution (step (b)).
また、本発明において、前記塩素系アルカリ洗浄剤溶液が０．１〜５重量％のアルカリ、０．０１〜０．４重量％の有効塩素を含むことが好ましい。 Moreover, in this invention, it is preferable that the said chlorine-type alkali cleaning agent solution contains 0.1 to 5 weight% of alkali and 0.01 to 0.4 weight% of effective chlorine.
更に、本発明において、前記キレート剤がアミノカルボン酸系キレート剤であると好ましく、中でもエチレンジアミン四酢酸塩（以下「ＥＤＴＡ」という）、Ｌ−グルタミン酸二酢酸塩（以下「ＧＬＤＡ」という）、メチルグリシン二酢酸塩（以下「ＭＧＤＡ」という）、ニトリロ三酢酸塩（以下「ＮＴＡ」という）、が好ましい。 Furthermore, in the present invention, the chelating agent is preferably an aminocarboxylic acid chelating agent. Among them, ethylenediaminetetraacetate (hereinafter referred to as “EDTA”), L-glutamic acid diacetate (hereinafter referred to as “GLDA”), methylglycine Diacetate (hereinafter referred to as “MGDA”) and nitrilotriacetate (hereinafter referred to as “NTA”) are preferable.
本発明によると、例えば牛乳、飲むヨーグルト、ミルク入りコーヒーのようなミルク入り飲料などの有機物だけでなく無機物をも多く含む製品の生産設備のＣＩＰ洗浄において行われているアルカリ洗浄工程の後に行っていた酸洗浄工程を省略することにより、中間リンス工程を含めて省略でき、きわめて効率のよいＣＩＰ洗浄を行うことができる。 According to the present invention, for example, it is carried out after the alkali cleaning step performed in the CIP cleaning of the production facility of products containing a large amount of inorganic substances as well as organic substances such as milk, drinks with yogurt, and beverages with milk such as coffee with milk. By omitting the acid cleaning step, the intermediate rinsing step can be omitted and extremely efficient CIP cleaning can be performed.
次に本発明の好ましい実施の形態について説明する。 Next, a preferred embodiment of the present invention will be described.
