Description

A cooling device of draft beer

The present invention relates to a draft beer cooler, and more particularly, to a draft beer cooler capable of cooling draft beer supplied from a draft beer feeder without using cooling water to a predetermined temperature and drawing the draft beer into a draft beer outlet valve.

Generally, beer is divided into bottle beer, which is manufactured through heat treatment process such as heating and sterilization process, and draft beer, which is manufactured without heat treatment process such as heating and sterilization process. The draft beer is contained in a carbon dioxide gas compression container The carbon dioxide gas (CO 2 ) is supplied to the draft beer feeder to be drawn out. At this time, the draft beer, which is supplied with carbon dioxide gas, is cooled and cooled, so that it is possible to feel cool and fresh taste unique to the draft beer. The draft beer cooler is constructed so that the draft beer can be rapidly cooled to a temperature close to 0 캜 and taken out.

Most of the conventional draft beer coolers are divided into a cooling chamber in which cooling water is stored and a machine room in which a cooling device for cooling the cooling water is installed as in the Utility Model Registration No. 20-0218911, The refrigerating apparatus includes a compressor for compressing the gas refrigerant to a high temperature and a high pressure, a condenser for condensing the gaseous refrigerant compressed in the compressor into a liquid phase, and a coolant stored in the cooling chamber by rapidly expanding the liquid coolant, An evaporator for rapid cooling, that is, a refrigerant circulation line spirally arranged in the cooling water stored in the cooling chamber, and the like. In order to operate the refrigeration apparatus installed in the machine room, As shown in FIG.

When the draft of the draft beer cooler is divided into the machine room in which the freezing device is installed and the cooling room in which the cooling water is stored, when the moisture of the cooling water stored in the cooling room penetrates into the machine room, It is necessary to prevent the cooling water stored in the cooling chamber from penetrating into the machine room and to prevent the cooling water stored in the cooling chamber from being spirally installed in the cooling chamber In order to cool the draft beer supplied to the draft beer line to a sufficiently low temperature close to 0 ° C, the cooling chamber must be made large so that the cooling water storage capacity stored in the cooling chamber becomes large, so that the volume of the draft beer cooler becomes large And the production ratio of the draft beer cooler is thereby increased. Most of the draft beer coolers used in the past have a stirrer for agitating the cooling water using a stirring motor so as to cool the draft beer draft line installed in a state in which the cooling water stored in the cooling chamber is immersed in the cooling water, Since the stirring motor is normally operated for 24 hours at a time, the amount of electricity used is increased. In particular, since the stirring motor rotates at a high speed of 280 to 300 rpm, It is pointed out that there is a problem that machine parts such as bearings cause malfunction or noise due to wear phenomenon or that the rate of occurrence of fire due to overheating of the stirring motor is large, Economical burden on business handling draft beer It is a situation that appears to be the biggest problem, as well as act as that from the dangers of fire safety can be guaranteed.

Therefore, in order to solve the above problems, the applicant of the present invention has proposed a draft beer cooler of Patent No. 10-1480960.

In the prior art, a cooling mold made of a metal material is immersed in cooling water stored in a cooling chamber, and a draft beer extraction line is spirally embedded in the cooling mold, However, the size of the cooling chamber may be reduced to some extent. However, in order to prevent water from penetrating into the machine room, it is necessary to waterproof the machine room and to reduce the total volume of the machine room and the cooling chamber. there is a problem that a stirring motor for stirring the cooling water easily breaks down or a noise is generated and a fire may occur due to overheating of the stirring motor.

In the case where the draft beer cooler is configured to cool the draft beer draft line installed in the cooling chamber by cooling the cooling water stored in the cooling chamber as in the prior art described above, However, if the cooling water stored in the cooling chamber is not replaced at regular intervals, the draft beer extracting line (for example, 20 to 30 days) There is a problem that the cooling water needs to be replaced with new cooling water during the period in which the cooling water is set and the cooling chamber must be cleanly cleaned.
