Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a novel cleaning agent and a new cleaning method for beer dispensers, and more particularly to at least a part of a dispenser for beer, especially for draft beer.
For example, a cleaning agent for the coil and other parts and a method for cleaning the same, and more specifically, a detergency by containing percarbonate such as percarbonate, perborate and persulfate as a main component of the cleaning active substance. The present invention also relates to a dispenser cleaner for beer, particularly draft beer, which is excellent in handleability, and a method for cleaning the dispenser using the same.

[0002]

2. Description of the Related Art For example, solid matter (tartar, etc.) in beer usually adheres to stainless steel parts installed in a draft beer dispenser (cooling tank), especially to the inside of its coil. Leaving these solids as they are will not only impair the taste of the beer, but are also not hygienic. Therefore, after the dispenser is used, the coil is cleaned by passing a sponge inside the coil. Further, when the cleaning cannot be completely performed by the cleaning through a sponge, the cleaning is periodically performed using a cleaning agent, particularly a strong alkaline cleaning agent containing a strong alkali substance such as sodium hydroxide as a main component.

[0003]

A strongly alkaline cleaning agent adheres to the skin or the like, and if left unattended, the skin becomes rash. Therefore, it is necessary to handle the cleaning agent so that it does not adhere to the cleaning agent. In order to prevent contact with skin, etc., wash workers should use protective equipment (safety glasses, rubber gloves,
It is the fact that the wearer wears a protective apron, etc., cures around the dispenser with a vinyl sheet or the like, and pays attention so that it does not adhere to the skin. Furthermore, after washing, it is necessary to neutralize the waste liquid and the like with a neutralizing agent.
Therefore, development of a detergent which is non-alkaline and easy to handle with a beer dispenser has been awaited.

[0004]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, a peroxo-acid salt which is relatively safe even if it adheres to the skin or the like to a cleaning agent is mainly used as a cleaning active substance. The inventor has found that a cleaning effect equivalent to that of a strongly alkaline cleaning agent can be obtained by incorporating the same as a component, thereby completing the present invention. According to this peroxo acid salt, the handling property is simple, and the effect of washing can be obtained to the same degree as that of a conventional strong alkaline detergent.

That is, the present invention provides a beer dispenser,
Particularly in coil cleaners, beer containing a peroxoacid salt as a main component of the cleaning active substance, particularly in at least a part of a draft beer dispenser, particularly using a cleaner for the coil or beer hose, and using the cleaner. This is a method for cleaning a part of the beer dispenser which circulates a necessary part in the beer dispenser, particularly a coil, a beer hose and the like.

As the peroxo acid salt, percarbonate,
It is preferred to use at least one of perborate and persulfate.

Further, it is preferable that the cleaning agent of the present invention further contains, for example, a cationic, anionic, zwitterionic or nonionic surfactant in order to enhance the cleaning effect.

The content of the peroxoacid salt used in the present invention is preferably at least 50% by weight, particularly preferably 60 to 80% by weight in terms of dry matter. If the amount is more than this range, the effect does not change, and if the amount is too small, there is a problem in the cleaning effect.

Further, the cleaning agent of the present invention includes a cleaning agent in the form of an aqueous solution, and is particularly preferable for cleaning the coil of the dispenser. In the case of an aqueous solution for actually cleaning the coil, the preferred concentration of the peroxoacid salt is 0.1.
The content is 1 to 10% by weight, particularly preferably 0.5 to 3% by weight.

The temperature of the cleaning agent in the form of an aqueous solution used in the cleaning method of the present invention is preferably dissolved in warm water of 30 to 60 ° C., and the inside of the coil, for example, is circulated and cleaned by a manual or electric pump type washer. . If the temperature is too high, there is a problem that it takes time to re-cool the dispenser after cleaning, and if it is too low, there is a problem that the detergent is difficult to dissolve and the cleaning effect is reduced.

In the present invention, for example, the pH value of the aqueous solution of the cleaning agent used for cleaning the coil is preferably less than 11, particularly preferably 10 to 11. If the pH value is too high, there is a problem in safety, and if the pH value is too low, there is a problem in the cleaning effect and the like.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a detergent and a method for cleaning a beer dispenser of the present invention will be described in detail.

As the peroxoacid salt used in the present invention,
Preferably, percarbonates such as sodium percarbonate, perborates such as sodium perborate, and persulfates such as sodium monopersulfate and potassium monopersulfate can be used. One of the features of the cleaning agent of the present invention is that a strong alkaline substance is not used as the main component of the cleaning active substance, but a strong alkaline substance is slightly mixed and used within a range that does not interfere with handling and health. You can also. In this case, it is sufficient that the pH value in the aqueous solution is less than 11, and such a detergent is also included in the present invention.

In the present invention, a surfactant can be used as a penetrating agent, if necessary. Examples of the surfactant include cationic, anionic, nonionic and zwitterionic surfactants. Either can be used. The content of the surfactant is preferably 0.001 to 10% by weight in a dry form, particularly preferably 0.01 to 3% by weight.
% By weight, preferably in the form of an aqueous solution, from 0.0001 to 0.1%.
It is 5% by weight, particularly preferably 0.001 to 0.1% by weight.

Examples of the anionic surfactant include an alkylbenzene sulfonate and a dialkyl sulfonate. Examples of the cationic surfactant include a nonionic surfactant such as an alkyltrimethylammonium salt. For example, higher alcohol ethylene oxide adducts and zwitterionic surfactants include, for example, alkyl betaine salts and alkyl amino acid salts.

The detergent of the present invention contains a peroxoacid salt, and the surfactant can be used if necessary. In addition, phosphates, silicates, carbonates, enzymes, and sodium ethylenediaminetetraacetate can be used. Organic chelating agents such as sodium nitrotriacetate and sodium polyacrylate, and other additives, adjuvants, and extenders conventionally added and blended as detergents in this field can also be used as appropriate.

There is no particular difficulty in cleaning a beer dispenser using the cleaning agent of the present invention. The cleaning agent is prepared in the form of an aqueous solution (at a temperature of 30 to 60 ° C. and a pH of 10 to 11).
The coils can be cleaned manually or by circulating them with an electric pump.

(Evaluation Results) The evaluation results are shown in Table 3.

[0025]

[Table 3]

In the evaluation methods in Table 3, ○ indicates that the stain is completely removed; and Δ indicates that the removal of the stain is less than half.

As is clear from the above results, the detergent of Comparative Example 3 has a problem in detergency, and the detergents of Comparative Examples 1 and 2 have a problem in that they are strongly alkaline. The cleaning agent of the present invention was found to have the same detergency as a conventional sodium hydroxide-containing cleaning agent (strong alkali) despite being weakly alkaline when used at a predetermined concentration in the form of an aqueous solution. As a result, it was also found that when the cleaning agent of the present invention was washed in the form of a predetermined aqueous solution, for example, the inside of a dispenser coil, dirt was easily removed.

[0028]

The beer dispenser detergent and method according to the present invention are characterized in that at least a part of the draft beer dispenser, in particular the coil detergent, comprises a peroxoacid salt as a main component of the cleaning active substance. In addition to providing a cleaning agent that is much easier to handle than conventional strong alkaline cleaning agents and has an excellent cleaning effect, a predetermined aqueous solution of the cleaning agent is circulated in the coil, for example. As a result, dirt can be extremely easily and easily removed as compared with a conventional strong alkaline cleaning agent, so that an environment-friendly cleaning agent and a cleaning method with excellent handling properties can be provided.
