Abstract

PURPOSE:To simply pour beer having a satisfactory air bubble ration by a method wherein during the initial stage of a pouring of beer, a container is held in an inclina tion state, and when beer in a container is increased to a some level, the container is rotated around a horizontal axis serving as a fulcrum by means of the weight of beer, and the container is brought into a standing-upright state. CONSTITUTION:When a handle is operated, a dispensing valve 2 is opened, and the flow of beer is produced. In which case, beer flowing through a pouring port 15 flows in a container 16 and collided with an inclining inner wall surface 16a. The beer gathers in a valley formed between an inner wall surface 16a and a bottom surface 16b to form a level A. When a beer surface is gradually raised and a level is raised to B, rotation moment in a counterclockwise direction exerted on a container support bed 18 by means of the weight of beer is balanced with rotation moment in a clockwise direction. When the level is further raised, the rotation moment in a counterclockwise direction is against the rotation moment is a clockwise direction. The container support bed 18 is slowly rotated and is collided in a position shown by a two-dot chain line, where the container 16 stands upright, with a stopper 30 protruded from the front of a mounting bed 23 and stopped. With this state, pouring is effected up to a proper level in the container, and a dispensing valve 2 is closed.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a beer dispenser that cools beer in a barrel and dispenses it into a container such as a cup or jug, and more specifically, a beer dispenser equipped with a movable container holder that can easily extract beer with a good foam ratio. Regarding.

[Conventional technology]

The general structure of a conventional beer dispenser will be explained with reference to FIG. In the figure, 1 is the dispenser body, a dispensing valve 2 attached to the front, a cooling coil 3 whose one end is connected to the dispensing valve 2, a water tank 4 containing the cooling coil 3, and water 5 in the water tank 4. It is composed of a cooler 6 that cools the air conditioner, a refrigerator 7 that supplies refrigerant to the cooler 6, and the like. 8 is a beer barrel, and 9 is its dispensing head. The dispensing head 9 is connected to the other end of the cooling coil 5 by a beer pipe 10, and is also connected to a carbon dioxide gas cylinder 13 by a gas pipe 11 via a pressure reducing valve 12. In such a beer dispenser, the handle 14
When the dispensing valve 2 is opened by tilting it forward, the beer in the beer barrel 8 is reduced to 1 to 3.5 kg by the pressure reducing valve 12.
/d is pushed out from the dispensing head 9 by the carbon dioxide gas from the cylinder 13, which is depressurized to
is extracted into the mug 16 from the extraction port 15. While passing through the cooling coil 3, this beer is cooled to an appropriate temperature by the water 5 cooled by the cooler 6. Handle 14
The operation is carried out by the worker 17 who holds the mug 16 with one hand and inserts it into the extraction port 1.
Do this with your other hand while applying it diagonally to step 5.

[Problem B that the invention attempts to solve]

However, such conventional beer extraction has the following problems. (1) Since the extraction work is carried out by holding the container 16 with one hand, it is extremely tiring when extraction is performed many times or when performed by a woman. By the way, the container 16 that is usually used is a glass jug, but there are various types depending on the internal volume, and generally the internal volume is 40.
0cc, weight 0.89kg, weight 1.21kg when beer is extracted to 80% of the internal volume, maximum, internal volume 1000cc, weight 1.47kg, weight 2 when beer is extracted to 80% of the internal volume. Ranges up to .27 kg are used. (2) As a countermeasure to this problem, it is possible to extract beer by standing the container 16 vertically on a stand provided below the extraction port 15 (pour the beer in place), but if you do this, the extracted beer will There is a problem in that the carbon dioxide gas that collides with the bottom of the container 16 and is dissolved in the beer is separated into gas and liquid, resulting in excessive foam. Generally, the ratio of the liquid part to the foam part in the container immediately after extraction is 7.
:3 to 8:2 is said to be preferable, but if you pour it over, the ratio of foam will become larger than this. (3) In recent years, the sale of beer using beer dispensers has been expanding widely to the food and beverage industry such as family restaurants, and it is desired to save labor by automating the extraction process. In that case, even if the dispensing valve 2 is opened and closed electrically and automatic extraction is attempted by simply operating a push button, the above-mentioned problem of the foam ratio due to pouring becomes a bottleneck. This invention was made in view of this situation,
The purpose of the present invention is to provide a beer dispenser that enables pouring while obtaining an appropriate foam ratio, reduces worker fatigue, and enables automatic extraction.

[Means to solve the problem]

In order to achieve the above object, the present invention maintains a container in an inclined state at the initial stage of beer extraction, and when the beer in the container reaches a certain level, the weight of the beer rotates the container around a horizontal axis. A movable container holder for holding the container in an upright position is provided below the beer outlet. Further, the present invention realizes automatic extraction by providing the beer dispenser with means for opening a dispensing valve for a certain period of time by operating a push button.

[For use]

When we receive a glass of bottled beer at a banquet, we first tilt the cup to pour, and as the liquid level rises, we turn the cup upright. This is to prevent the beer from foaming excessively; by tilting the container, the collision surface of the beer falling from the mouth of the bottle changes from the bottom of the cup to the inner wall, which reduces the distance the beer falls. As it becomes shorter, the vertical collision with the bottom surface becomes an oblique collision with the slanted inner wall surface, which reduces the amount of gas-liquid separation and air entrainment at the time of collision.■ Collision with the slanted inner wall surface of the cup during the extraction process This is based on the principle that the beer flows along this slope and gradually accumulates in the cup from the bottom of the valley formed by the bottom and inner wall, reducing the amount of air entrained. This invention focuses on the fact that the weight of the container increases as the extraction of beer from the beer dispenser progresses.At the beginning of extraction, when the weight of the container is small, the container is held in a tilted position, so that the beer can be extracted to a certain extent. If the weight of the container exceeds a certain limit, due to the weight balance,
A movable container holder that rotates about a horizontal axis to hold the container upright is provided to realize the principle of diagonal pouring. Furthermore, by providing a movable container holder according to the present invention, by providing a means for opening the dispensing valve for a certain period of time by operating a push button, automatic operation that allows no touching of either the dispensing valve or the container during extraction is possible. A brew-type beer dispenser can be configured.

【Example】

Hereinafter, the present invention will be explained in detail based on the drawings. In addition,
Parts corresponding to those in the conventional example are given the same reference numerals. 1 and 2 show a first embodiment of the present invention, with FIG. 1 being a perspective view of the front portion of a beer dispenser, and FIG. 2 being a longitudinal sectional view thereof. In the figure, 18 is according to the present invention;
It is a movable container holder provided below the extraction port 15, and includes a bottom plate 19 on which the container (cup) 16 is placed, a back plate 20 that intersects with the bottom plate 19 in an L shape and supports the sides of the container 16, and a back plate 20 on the left and right sides of the back plate 20. It consists of a side plate 21 provided to form a U-shape, and two left and right weights 22 attached to the upper part of the side plate 21. This container holder 18 is supported by a U-shaped mount 23 attached to the front surface 1a of the dispenser main body 1 so as to be rotatable back and forth by a horizontal shaft 24. In FIG. 2, the container pedestal 18 is rotated counterclockwise around the axis 24 mainly by the weight of the container 16 and by the weight 22.
However, when the container 16 is empty, the clockwise rotation moment prevails, and the container holder 18 rotates clockwise, causing the back plate 20 to move to the upper end of the mount 23. 23a and is stopped as shown. Accordingly, the container 16 is in an inclined state. On the other hand, the dispensing valve 2 shown in detail in FIG.
The nut 2 is attached to the upper end 3a of the cooling coil 3 where the valve body 25 protrudes from the front surface 1a of the dispenser body 1.
They are joined by 6. A slide valve 27 that slides left and right to open and close a flow path between the valve body 25 and the valve seat 25a is housed in the valve body 25, and is adapted to be interlocked with the handle 14. A tip 14a of the handle 14 is loosely fitted into a slide valve 27, and the handle 14 is configured to swing from side to side in the figure with a spherical portion 14b gripped by a nut 29 via a guide 28 as a fulcrum. Here, in FIG. 2, when the handle 14 is operated in the direction of the dashed arrow from the position indicated by the two-dot chain line to the position indicated by the solid line, the dispensing valve 2 opens as shown in the figure, and beer flows as indicated by the arrow. Therefore, the beer flowing out from the extraction port 15 flows into the container 16 and the inclined inner wall surface 16a.
along the inner wall surface 16a and the bottom surface 1.
It collects in the valley created by 6b and forms water level A. When the liquid level gradually rises and reaches the water level B, the counterclockwise rotational moment acting on the container holder 18 due to the weight of the beer balances with the clockwise rotational moment. As the water level rises further, the counterclockwise rotational moment becomes dominant, and the container holder 16 slowly rotates in the direction shown by the broken line arrow, and the mount 23 is moved to the position shown by the two-dot chain line, where the container 16 stands upright. It stops when it hits a stopper 30 that protrudes from the front. In this state, extraction is further carried out to an appropriate water level, and the dispensing valve 2 is closed. When the container 16 containing beer is taken out from the container holder 18, the container holder 18
It flips over under its own weight and returns to its tilted state. According to the illustrated configuration, since the container 16 is held in an inclined state at the initial stage of beer extraction, the falling distance of the beer from the extraction port 15 to the inner wall surface 16a of the container 16 where the beer collides is shortened, and the beer The collision with the container 16 becomes an oblique collision with the inclined inner wall surface 16a, which reduces gas-liquid separation and the amount of air entrained during the collision, and furthermore, beer flows along the inclined inner wall surface 16a during the extraction process. Since the air gradually accumulates in the cup from the bottom of the valley formed by the bottom surface 16b and the inner wall surface 16a, the amount of air trapped is reduced. FIG. 3 shows a second embodiment of the present invention, which differs from the first embodiment in that the dispensing valve 2 is operated by an NN solenoid to perform automatic extraction. ing. That is, in FIG. 3, 31 is an electromagnetic actuator attached to the dispenser body 1 so as to be located above the dispensing valve 2, and the cover 32
Inside is a control section 34 equipped with a push button 33 protruding from the front.
, an electromagnetic solenoid 35, and a lever 37 supported by a shaft 36 and having one end facing the plunger 35a of the electromagnetic solenoid 35.
etc. are accommodated. On the other hand, the handle 14 (FIG. 2) of the dispensing valve 2 is omitted, and instead a slide valve 27 is extended forward, and the other end of the lever 36 is engaged with the front end 27a of the slide valve 27. With this configuration, when the push button 33 is pressed, the electromagnetic solenoid 35 is energized, and the plunger 35a is attracted to the left in the figure as shown by the arrow 1, and the lever 36 is driven counterclockwise. Push the slide valve 27 in the direction indicated by the dashed arrow to open the dispensing valve 2. As a result, beer is extracted into the container 16 on the container holder 18, as in the first embodiment, and the container holder 18 rotates to the state shown by the two-dot chain line. The excitation of the electromagnetic solenoid 35 is time-controlled by the control unit 34, and is automatically demagnetized when beer extraction is finished. As a result, the lever 36 returns to the illustrated position by the action of a return spring (not shown), and the dispensing valve 2 is closed. According to the second embodiment, by simply placing the container 16 on the container pedestal 18 and operating the push button 33, a certain amount of beer is automatically extracted without any touch.

[Effects of the Invention] According to the present invention, beer can be extracted while the container is placed on the container holder, and there is no need to support a heavy container during extraction, which reduces fatigue. Furthermore, since the container is always rotated in a constant pattern from the tilted state at the beginning of extraction to the upright state at the end, even unskilled people can extract beer with a constant foaming rate every time. Furthermore, by performing automatic extraction by operating the dispensing valve with a motor or electromagnetic solenoid, the time until the extraction is completed can be used for other tasks, resulting in a large labor-saving effect. By the way, according to an experiment, beer in a beer barrel with a temperature of 29.6℃ was pushed out at a carbon dioxide pressure of 3.1kg/ci,
When 8 cups are extracted every 15 seconds using a paper cup with a capacity of 545 cc, the average product temperature immediately after extraction is 3.8°C, the average volume of the beer liquid part is 390 cc, and the average volume of the beer foam part is 120 cc. , the ratio of liquid part to foam part is 7.
It was 672.4.
