Abstract

PURPOSE:To pour out draft beer in an Coanda stream, suppress beer froth formation upon pouring and form a uniformly fine froth by a method wherein the inner surface of a draft cock with which an opening and closing valve slidably contacts is curved or inclined and a slit part is formed between the valve and the inner surface thereof. CONSTITUTION:When a lever 7 is moved in the direction A, a slide valve rod 6 is moved downwards to bring a valve 5 into contact with the curved surface 3 of a cylindrical part 4. Therefore, the draft beer introduced from an entrance opening 1 is not poured out from a supply opening 2. When the lever 7 is moved in the direction B, the valve 5 is moved upwards to form an annular slit part 8 between itself and the curved surface 3. Therefore, the draft beer is poured out from the supply opening 2. At this time, the draft beer is allowed to flow in an Coanda stream due to the existence of the curved surface 3 and the slit part 8 to localize the flow speed and density along the axial part of the draft cock. As a result, the formation of the beer froth upon pouring out draft beer can be suppressed and a uniformly fine froth can be formed.

2. Description of the Related Art Conventionally, when pouring draft beer into a glass or a jug, draft beer mixed with carbon dioxide in a pressurized state has a valve that can be opened and closed by a lever operation. I'm trying to pour through. Usually, carbon dioxide gas having a pressure of about 1 to 3 kg / cm 2 is used for pouring and supplying the draft beer.

However, although this conventional draft cock is easy to operate, a large amount of foam is generated when it is poured into a glass, and in some cases, the glass is full of foam, which may cause a problem in restaurants, beer halls, etc. The various places in the country were unpopular with people who enjoyed draft beer. Although the foaming can be suppressed to some extent by the technique of the employee who operates the lever, it requires skill and it is difficult to significantly suppress the foaming.

The reason why such bubbles are noticeable is that bubbles having a diameter of about 3 to 5 mm or even larger are generated, but the bubbles themselves are made smaller and uniform so that the bubbles themselves are not noticeable and their generation. The reality is that measures that can reduce the amount have not yet been established.
The present invention has been made in view of the circumstances as described above, and improves the drawbacks when using a conventional draft cock for draft beer, suppresses the amount of foam itself generated, and also aims to make the bubbles fine and uniform. It aims to provide a new means of doing things.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 of the accompanying drawings is a sectional view illustrating the structure of a draft cock for beer supply according to the present invention.
For example, as shown in FIG. 1, the draft cock of the present invention has an inlet (1) connected to a supply tank for draft beer mixed with carbon dioxide, and a supply / discharge opening (2) for pouring beer into a glass or the like. And a cylindrical portion (4) having a curved surface or an inclined surface (3) having a diameter gradually increasing from the supply / discharge port (2), and the curved surface or the inclined surface (3).
A valve (5) which can be freely connected to and detached from the slide valve, a slide valve rod (6) connected to this valve (5), and further, this slide valve rod (6)
And a lever (7) that can slide.

In the state shown in FIG. 1, when the lever (7) is tilted toward the direction A, the slide valve rod (6) slides downward and the valve (5) abuts the curved surface or the inclined surface (3). . In this contact state, the beer introduced from the introduction port (1) is not discharged from the supply discharge port (2). On the other hand, when the lever (7) is tilted in the direction B, the valve (5) moves upward, and between the valve (5) and the curved surface or the inclined surface (3), the valve (5) moves to the direction shown in FIG. As also shown, the annular slit portion (8) is formed. In this state,
Beer flows along the arrow C in the figure and is discharged from the supply / discharge port (3).

Beer flowing out from the slit portion (8) is
Since it is pressurized by mixing with carbon dioxide, it flows out at high speed. At this time, in the structure of the draft cock of the present invention, due to the existence of the curved surface or the inclined surface (3) and the slit portion (8), the beer forms a so-called Coanda flow in which the speed and density concentration are formed in the central portion of the shaft. To do. At this time, a swirling (spiral) flow is generated depending on conditions such as the pressure, the width (W) of the slit portion (8), the inclination angle (θ) of the curved surface or the inclined surface (3), and the like. This further promotes concentration of velocity and density in the axial center.

In the conventional draft cock, the flow is not a Coanda flow but a turbulent flow and diffuses from the supply / discharge port (2) in the direction of arrow D in the figure. In the past, this diffusion has been the cause of producing a large amount of bubbles having a large diameter. However, since the Coanda flow of the present invention and further the Coanda spiral flow cause the concentration E at the center of the shaft as shown in the figure, the conventional cause of bubble generation is significantly weakened. For this reason, not only the number of bubbles generated per se is reduced, but also the generated bubbles are finely homogenized.

Such a Coanda flow generally has a ratio d / D of 1 / d with respect to the pipe inner diameter (d) (D) in FIG.
In the case of about 4 to 1/8, it can be generated by setting the inclination angle θ to 5 to 40 ° and the slit width (W) to about 1/10 to 1/20 as W / d. The pressure of beer at this time can be set in an appropriate range of 1 to 4 kg / cm 2 .
