Description

BEER SUPPLYING SYSTEM INCLUDING LINE-STERILIZATION APPARATUS AND LINE-STERILIZATION METHOD}

The present invention relates to a beer supply system and a beer supply line sterilization method having a beer supply line sterilization apparatus, and provides a delicious and fresh beer by quickly and easily sterilizing the inside of the supply line to which beer is supplied without a separate chemical treatment. It relates to a beer supply system having a beer supply line sterilization device and a supply line sterilization method.

Beer is fermented and fermented wort. In particular, draft beer is a kind of beer that is filtered and not subjected to heat sterilization. Such draft beer is stored in a beer storage tank and provided to a beer sales office, and a cold beer is provided to a customer through a predetermined supply system.

A basic configuration for providing a customer with beer stored in such a beer storage tank will be described with reference to FIG. 1. 1 is a configuration diagram schematically showing a general beer supply system.

As shown in FIG. 1, a general beer supply system includes a beer storage tank 1 in which beer is stored; A pressure gas tank 2 for storing and discharging pressure gas such as carbon dioxide; A beer cooler (3) for cooling and discharging the beer discharged from the beer storage tank; And an emitter 4 through which beer is finally discharged.

The beer storage tank 1, beer cooler 3 and ejector 4 are connected via a supply line 5.

Since beer contains a lot of nutrients such as protein and sugar, the remaining components of the beer will be deposited in the supply line, such as beer stone, while the beer stays inside the beverage supply system, and bacteria propagation is very fast. Happens.

When bacteria grow inside these beer supply lines, not only there is a danger of food poisoning and the like, but also the taste of beer is altered, so the hygiene management of the supply line must be thoroughly conducted for safety and preservation of taste.

However, in reality, because the supply line is very narrow and long, it is difficult to clean it, and disassembling the entire beer supply system for cleaning is a very cumbersome task.

Washing only with water is difficult to remove the bacteria present in the supply line, and the remaining bacteria grow rapidly. In addition, washing with water may not effectively remove much of the nutrients remaining inside the supply line, which may temporarily delay bacterial growth, but it is not possible to solve the underlying bacterial growth in the supply line. In addition, when only washing with water takes a lot of time and there is a problem that the consumption of water increases.

In this case, in order to solve the problem of washing only with water, there is a case in which a separate drug is mixed and washed, but in this case, the cost of the drug is not only added to the washing, but the washing effect also has a short-term limitation.
