The present invention relates to a draft beer container injecting apparatus, and more particularly, to a draft beer container injecting apparatus for injecting a draft beer into a container together with carbon dioxide gas.

As is well known, beer is classified into bottled beer and draft beer. In the process of producing beer, the beer is subjected to heat treatment such as heating and sterilization. In contrast, in the process of producing beer, the beer is not subjected to heat treatment such as heating and sterilization Called draft beer.

Because the draft beer does not undergo the above-mentioned heat treatment process, it contains a self-generated carbon dioxide gas due to the action of the remaining yeast, and thus has a unique and unique flavor and aroma.

In this case, in order to keep the taste and aroma of the draft beer in a container, a certain amount of carbon dioxide gas is injected with the raw draft beer into the container in order to enjoy the fresh and unique original taste and aroma of the draft beer freely in various places. .

In particular, it is very important to maintain the amount of carbon dioxide gas contained in draft beer at a constant level in order to keep the draft beer fresh and unique in its own flavor and aroma. To achieve this, it is necessary to fill the container with carbon dioxide gas, And it is preferable to discharge excess carbon dioxide gas that is excessively filled in the container.

However, in the case of conventional draft beer container injecting devices for providing draft beer in a container, conditions for discharging carbon dioxide gas, draft beer stock solution, and surplus carbon dioxide gas are not adequately prepared, so that the amount of carbon dioxide in draft beer contained in the container is kept constant So that the freshness, unique taste and flavor of draft beer are deteriorated.

First, the draft beer stock solution supply path 50 forms a supply passage connecting the opening / closing valve unit 20 so that the raw beer stock solution supplied through the connected draft beer stock supply pipe 110 can be injected into the container 100 .

In the present embodiment, the draft beer stock solution supply path 50 is made up of the first draft beer stock solution supply path 51 and the second draft beer stock solution supply path 52.

The first draft beer stock solution supply passage 51 horizontally penetrates the upper side adjacent to the opening and closing valve part 20 of the body part 10 horizontally along the first direction (Y axis direction), and the two draft beer stock solution supply One of the drafts 16 is connected to the draft beverages stock solution supply pipe 110 and the tile side is closed with a closing bolt 111 or the two draft beer stock solution supply openings 16 are connected to the respective beverage stock solution supply pipes 110 ) To be connected continuously.

As such, the first draft beer stock solution supply passage 51 horizontally penetrates along the first direction (Y axis direction) of the body portion 10, so that the additional beer stock solution It is also possible to connect one or more draft beer container injection apparatuses 1 in series or in parallel by connecting the supply pipes 110 continuously.

The second draft beer stock solution supply path 52 is branched from the first draft beer stock solution supply path 51 inside the body 10 and is connected to the opening and closing valve unit 20.

The draft beer stock solution supplied through the draft beer stock solution supply pipe 110 is supplied to the valve opening and closing part 20 through the first draft beer stock solution supply path 51 and the second draft beer stock solution supply path 52, The carbon dioxide gas and the draft beer stock solution injected into the container 100 through the raw liquid feed path 70.

In the screw distributor 40, a gas through hole 41 is formed through the inside of the screw distributor 40 so as to communicate with the carbon dioxide discharge passage 80. Therefore, in the course of injecting and filling the raw beer stock into the container filled with the carbonic acid gas, surplus carbon dioxide gas in the container 100 flows through the gas through hole 41 and the carbon dioxide gas discharge path 80 of the screw distributor 40 Through which the exhaust gas is discharged.

On the other hand, the amount of carbonic acid gas discharged through the carbon dioxide gas discharge path (80) is controlled by a butterfly screw type gas discharge valve (not shown) formed to penetrate the body portion 10 in the second direction 19).

The spout 101 of the container 100 which is press-fixed through the container fixing part 30 in the course of injecting the carbonic acid gas and the raw beer stock into the lower part of the body part 10 on the side of the injection part 12, A ring-shaped sealing rubber 45 is fitted and fixed so that sealing is performed without leakage of the carbonic acid gas and the draft beer stock solution.

1 and 2, the opening / closing valve unit 20 includes a three-way valve including a body fastening unit 21, a valve moving unit 22, and a valve handle unit 23.

The body fastening portion 21 is screwed to the upper valve connecting portion 11 of the body portion 10 and is inserted into the body 10 through the operation of the valve knob 23 in a state in which the valve moving portion 22 is received. So that the carbonic acid gas supply path 60 or the draft beer stock solution supply path 50 can be selectively connected to the carbonic acid gas and the draft beverage stock solution injection path 70.

The carbonic acid gas supply path 60 and / or the draft beer stock solution supply path 50 may be closed or the carbonic acid gas supply path 60 or the draft beer stock solution supply path 50 may be closed in accordance with the left / right rotation angle of the valve handle 23, And the opening degree of the carbonic acid gas supply path 60 and the draft beer stock solution supply path 50 is adjusted in accordance with the up and down rotation angle to selectively connect the carbonic acid gas and the draft beer stock solution to the inside of the container 100 And the amount of the carbon dioxide gas and draft beer stock solution to be injected is adjusted.
