Description

The present invention relates to a foam measuring method and a foam measuring device for measuring foam in a foaming beverage.

Conventionally, various foam measuring methods and foam measuring devices for measuring foam in effervescent beverages have been known. Japanese Unexamined Patent Publication No. 6-167373 describes an automatic foam holding measuring method and an automatic foam holding measuring device. The foam holding automatic measuring device includes a CCD camera that captures the liquid level of beer poured into each of the five graduated cylinders from above, and an image processing device that captures image information captured by the CCD camera. The image processing device performs binarization processing on the image information, and detects the bubble portion as white and the liquid surface portion as black. A personal computer is connected to the image processing device, and the personal computer calculates the foam holding time from the area of the liquid level portion.

Japanese Unexamined Patent Publication No. 2000-180358 describes a foam retention evaluation device for evaluating foam retention of beer. The foam retention evaluation device includes a sensor located above the beer poured into the glass and measures the amount of light from the beer, and evaluates the foam retention based on the amount of light measured by the sensor. Since the bubbles are white, the reflectance of light is high, and since the liquid surface is not white, the reflectance of light is low. The above-mentioned foam retention evaluation device determines that there are bubbles in the region where the light reflectance is high and no bubbles in the region where the light reflectance is low, and evaluates the foam retention of beer.

The above-mentioned automatic foam holding measuring device evaluates the foam holding by image information, and the above-mentioned foam holding evaluation device evaluates the foam holding by the reflectance of light. By the way, the fine foam generated on the liquid of the effervescent beverage makes the appearance good before drinking and the good taste at the time of drinking remarkable, and also functions as a lid for preventing carbon dioxide gas and aroma from coming off. Further, the fine foam also has a function of preventing oxidation of the effervescent beverage due to contact with air.

The fine foam is not only produced when the effervescent beverage is poured, but also regenerated when the effervescent beverage is drunk. A layer of fine granular bubbles called frosty mist is formed at the boundary between the liquid and the foam of the effervescent beverage, and the frosty mist is stimulated during drinking to regenerate fine bubbles. When a large amount of frosty mist is generated, it is considered that a large amount of fine bubbles are regenerated, so it is important to measure the amount of fine bubbles regenerated. Therefore, in providing an effervescent beverage having foam that has a good appearance and mouthfeel and that exhibits various functions as described above, it is required to be able to measure the characteristics of fine foam.

An object of the present invention is to provide a foam measuring method and a foam measuring device capable of measuring the characteristics of fine bubbles.

The foam measuring method according to one aspect of the present invention is a foam measuring method for measuring foam in an effervescent beverage, in which a step of injecting the liquid and foam of the effervescent beverage into a beverage container and after injecting the foam. The step of tilting the beverage container after the first hour, the step of returning the tilted beverage container after the second time has passed since the beverage container was tilted, and the amount of foam generated inside the returned beverage container. It is provided with a step of measuring.

In this foam measuring method, the beverage container is tilted after the first hour has passed since the liquid of the effervescent beverage and the foam were poured into the beverage container. Thereby, by setting the time from the injection of the effervescent beverage to the drinking as the first hour, it is possible to simulate the state from the actual injection of the effervescent beverage to the drinking. .. Further, after the second time has elapsed from tilting the beverage container, the tilt of the beverage container is restored, and the amount of foam generated when the beverage container is returned is measured. Therefore, by setting the time for drinking by tilting the beverage container as the second hour, it is possible to measure the amount of foam regeneration after simulating the state from the time when the beverage is drunk until the beverage container is returned to its original state. Therefore, by measuring the amount of foam after simulating the actual drinking of the effervescent beverage, the amount of regenerated foam can be measured stably and accurately. As a result, it is possible to appropriately search for the conditions for regenerating foam after drinking. Furthermore, not only the amount of foam regenerated, but also other characteristics of the foam can be measured in a timely manner.

Further, the above-mentioned first time may be 10 seconds or more and 300 seconds or less. In this case, it is possible to more accurately reproduce the time from when the effervescent beverage is poured out until it is drunk. Therefore, the amount of fine bubbles regenerated can be measured more accurately.

Further, in the step of tilting the beverage container, the beverage container may be tilted so that the angle of the bottom of the beverage container with respect to the horizontal plane is 10 ° or more and 80 ° or less. In this case, the inclination of the beverage container during drinking can be simulated more accurately. Therefore, the amount of fine bubbles regenerated can be measured more accurately.

In the pouring process, the liquid and foam of the effervescent beverage are poured out from the server for pouring out the effervescent beverage, and before the pouring process, a hole is made in the closed container filled with the effervescent beverage. It may be provided with a step of pumping the effervescent beverage from the closed container to the server. In this case, since the effervescent beverage is pumped to the server by making a hole in a closed container filled with the effervescent beverage, the amount of regenerated foam of the effervescent beverage packed in the container can be measured. That is, since the amount of regenerated foam can be measured even for the effervescent beverage packed in a container, it can be a highly versatile foam measuring method.

The foam measuring device according to one aspect of the present invention is a foam measuring device for measuring foam in an effervescent beverage, in which a server for pouring liquid and foam of effervescent beverage into a beverage container and the liquid and foam are injected. It is provided with a tilting device for tilting the ejected beverage container and a foam measuring unit for measuring bubbles generated inside the beverage container by being tilted and returned by the tilting device.

This foam measuring device can simulate the state in which the effervescent beverage is drunk by tilting the beverage container in which the effervescent beverage is poured from the server with the tilting device. Further, by returning the beverage container tilted by the tilting device to the original position, it is possible to simulate the state from the time when the beverage is drunk until the beverage container is returned to the original position. The amount of foam regenerated can be measured by measuring the foam with the foam measuring unit when the beverage container is returned. Therefore, since the regenerated amount of foam can be measured after simulating the actual drinking of the effervescent beverage, the regenerated amount of foam can be measured stably and accurately. Further, this foam measuring device can timely measure not only the amount of foam regenerated but also other characteristics of foam for the beverage container after being tilted and restored.

Further, the foam measuring device described above may be provided with a lid which is attached to the beverage container and has a perforated portion through which liquid and foam are discharged. In this case, by providing the lid attached to the beverage container, it becomes possible to discharge the liquid and the foam from the perforated portion of the lid. The perforated portion of the lid makes it possible to reproduce the state in which the effervescent beverage is drunk in the mouth of the drinker. Therefore, since the beverage container can be tilted under conditions closer to actual drinking, the amount of fine foam regenerated can be measured more accurately.

The effervescent beverage may also be packed in a closed container before being dispensed from the server. In this case, since the foam can be measured even for the effervescent beverage packed in a container, the foam measuring device with high versatility can be obtained.

Further, the foam measuring device described above is provided with a perforator that is connected to the server and punches a hole in the airtight container, and the effervescent beverage inside the airtight container is pumped from the perforator to the server and poured into the beverage container. It may be issued. In this case, since the punching machine makes a hole in the closed container and pumps the effervescent beverage to the server, the amount of regenerated foam of the effervescent beverage packed in the container can be measured. That is, since the amount of regenerated foam can be measured even for the effervescent beverage packed in a container, the foam measuring device can be made more versatile.

According to the present invention, the characteristics of fine bubbles can be measured.

Hereinafter, the foam measuring method and the embodiment of the foam measuring device according to the present invention will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are designated by the same reference numerals, and duplicate description will be omitted as appropriate. In addition, the drawings are partially simplified or exaggerated to facilitate understanding, and the dimensions and the like are not limited to those described in the drawings.

FIG. 1 is a diagram showing an example of a target effervescent beverage 1 measured by the foam measuring method and the foam measuring device according to the embodiment. The effervescent beverage 1 is poured into the beverage container C, and includes the liquid 2 and the foam 3 located above the liquid 2 inside the beverage container C. The beverage container C is a container in which an effervescent beverage 1 such as a mug, a glass, or a cup can be placed.

The effervescent beverage 1 contains, for example, a gas-containing fermented liquor such as carbon dioxide gas, and is formed with a foaming property in which a layer of foam 3 is formed on the liquid 2 when poured into the beverage container C. It is a beverage having a foam-holding property in which the foam 3 is maintained for a certain period of time or longer. Specifically, the effervescent beverage 1 is, for example, a beverage having a NIBEM value of 50 seconds or more according to the EBC (European Brewery Convention) method. The NIBEM value is an index value indicating the foam retention characteristic of the beverage.

The effervescent beverage 1 may be a beer-taste beverage. Beer-taste beverages include beverages that taste like beer and beverages that give the drinker the sensation of drinking beer. A beer-taste beverage having an alcohol content of 1% or more is also referred to as a beer-taste alcoholic beverage. Further, the beer-taste beverage is a fermented malt beverage such as beer using malt as a raw material, sparkling liquor, non-alcoholic beer, and liqueur (for example, a beverage classified as "liqueur (foaming) (1)" under the Liquor Tax Law). , And a beer-taste malt beverage that does not use wheat or malt as a raw material (for example, a beverage classified as "other brewed liquor (foaming) (1)" under the Liquor Tax Law). The effervescent beverage 1 may be an effervescent beverage that is not a beer-taste beverage. Hereinafter, an example in which the effervescent beverage 1 is beer will be described.

The foam 3 of the effervescent beverage 1 is a so-called fine foam, which is different from the coarse foam generated by the impact of the liquid 2 on the beverage container C or the like. The fine foam is a creamy foam that improves the design and mouthfeel of the effervescent beverage 1, and also serves as a lid to prevent the aroma or carbon dioxide gas of the liquid 2 from coming out and the liquid 2 from being oxidized. It is preferable to be generated. Fine bubbles are also generated from the frosty mist 4 that appears at the boundary between the liquid 2 and the bubble 3.

The frosty mist 4 is a mist-like layer that appears at the boundary between the liquid 2 and the bubble 3. The frosty mist 4 is generated by applying gas pressure when the effervescent beverage 1 is poured into the beverage container C. Since the frosty mist 4 regenerates the foam 3 when the effervescent beverage 1 is drunk, the effect of improving the foam retention of the fine foam can be obtained. Specifically, when the effervescent beverage 1 is drunk, the frosty mist 4 comes into contact with the liquid 2, the foam 3, or the beverage container C and is stimulated, so that new foam 3 is regenerated from the frosty mist 4. When the frosty mist 4 appears clearly and the frosty mist 4 increases, the amount of foam 3 regenerated increases. With the foam measuring device and the foam measuring method of the present embodiment, it is possible to measure the regenerated amount of the foam 3.

As shown in FIGS. 2 and 3, the foam measuring device 10 according to the present embodiment includes, for example, a perforating machine 20 for making a hole in a closed container M filled with the effervescent beverage 1 and an effervescent beverage 1. A server 30 to be dispensed, a tilting device 40 for tilting the beverage container C containing the effervescent beverage 1, and a foam measuring unit 50 for measuring foam 3 of the effervescent beverage 1 are provided. The closed container M indicates a container in which the effervescent beverage 1 is packed, and may be a can filled with the effervescent beverage 1 or a bottle filled with the effervescent beverage 1. .. Further, the container filling means a state in which a container such as a can or a bottle is filled with an effervescent beverage and sealed.

As shown in FIG. 2, the drilling machine 20 includes, for example, a base 21, a support column 22 extending upward from the base 21, a base 23 located on the base 21, and a holding portion 24 for holding the closed container M. It includes a grip portion 25 provided above the holding portion 24, a rod-shaped portion 26 passed through the grip portion 25 and the holding portion 24, and a carbon dioxide gas cylinder 27. The base 21 has, for example, a rectangular parallelepiped shape, and is provided with a rotatable lever 21b on the side surface 21a. As an example, when the lever 21b is pulled to rotate the lever 21b, the base 23 protrudes upward from the base 21 and the closed container M is pressed under the holding portion 24.

The holding portion 24 and the gripping portion 25 are supported by the support column 22, and the holding portion 24 can change its position in the vertical direction with respect to the support column 22. A closed container M filled with the effervescent beverage 1 is placed on the table 23. The base 23 is movable up and down with respect to the base 21, and moves up and down according to the rotation operation of the lever 21b. For example, the closed container M, which is a can, is placed on the table 23 in an upside down state.

The rod-shaped portion 26 is provided with a grip portion 26a at its upper end, and can be moved up and down by having the grip portion 26a. The rod-shaped portion 26 is a portion for making a hole in the closed container M placed between the base 23 and the holding portion 24, and the hole is made in the closed container M by moving downward. A flow path F1 through which the effervescent beverage 1 of the closed container M flows extends from the grip portion 26a.

The carbon dioxide gas cylinder 27 supplies carbon dioxide gas to the effervescent beverage 1 and pumps the effervescent beverage 1 from the rod-shaped portion 26 to the flow path F1. The carbon dioxide gas cylinder 27 is connected to the flow path F1 via the flow path F2, the holding portion 24, and the rod-shaped portion 26, and the flow path F1 connects the drilling machine 20 and the server 30 to each other. Therefore, the effervescent beverage 1 inside the closed container M is pressure-fed to the server 30 from the closed container M having a hole through the rod-shaped portion 26 and the flow path F1 by the carbon dioxide gas from the carbon dioxide gas cylinder 27.

The server 30 is, for example, a beverage server for pouring out the effervescent beverage 1. The server 30 includes a base 31, a columnar portion 32 through which the effervescent beverage 1 is distributed, and a curan 33 branched from the columnar portion 32. For example, the columnar portion 32 extends upward from the base 31, and the curan 33 projects from the side surface 32a of the columnar portion 32. The curan 33 has a lever 33a that is swung by hand, a liquid pouring portion 33b that pours out liquid 2 in response to the swinging operation of the lever 33a, and bubbles 3 in response to the swinging operation of the lever 33a. It is provided with a foam ejection portion 33c to be discharged. For example, in a state where the beverage container C is arranged under the liquid injection unit 33b and the foam injection unit 33c, when the lever 33a is pulled (the lever 33a is swung to the right side of FIG. 2), the beverage is beverageed from the liquid injection unit 33b. Liquid 2 is poured into the container C. Further, when the lever 33a is pushed (the lever 33a is swung to the left side of FIG. 2), the foam 3 is dispensed from the foam dispensing portion 33c to the beverage container C.

As shown in FIG. 3, the beverage container C into which the liquid 2 and the foam 3 are poured is placed on the tilting device 40. The tilting device 40 supports and rotates a base 41, a support portion 42 extending upward from the base 41 in a pair, a rotating portion 43 rotatable with respect to each support portion 42, and a beverage container C. A container rotating portion 44 that rotates together with the portion 43 is provided. The support portion 42 includes a pair of columns 42a extending upward from the base 41 and a support 42b supported by each column 42a, and a rotating portion 43 is horizontally inserted through each support 42b.

The rotating portion 43 extends horizontally between the pair of supports 42b, and includes a motor 43a and a control portion 43b on the outside of the pair of supports 42b. The motor 43a generates a rotational driving force that rotates the container rotating portion 44 with the rotating portion 43 as the central axis, and the control unit 43b controls the motor 43a. As shown in FIGS. 3 and 4B, the beverage container C rotates with the container rotating portion 44 about the rotating portion 43 as a central axis. In the control unit 43b, for example, an angle θ of the bottom portion C1 of the beverage container C with respect to the horizontal plane H, a time until the bottom portion C1 rotates to the angle θ, a time for maintaining the angle θ, and the like can be set. The control unit 43b controls the motor 43a so that the beverage container C is tilted at a set angle θ and time.

The container rotating portion 44 has a base 44a on which the beverage container C is placed, a connecting portion 44b that connects the base 44a and the rotating portion 43 to each other, and a lid that extends upward from the connecting portion 44b and covers the upper end of the beverage container C. It is equipped with 44c. In FIGS. 4A to 4C, a part of the container rotating portion 44 is not shown. The connecting portion 44b includes a pair of wall portions 44d extending upward from each of the left and right ends of the table 44a, and the beverage container C is placed between the pair of wall portions 44d. The base 44a and the pair of wall portions 44d are located above the base 41 and are separated from the base 41. The lid 44c is connected to the connecting portion 44b via a portion 44e extending upward from one of the two wall portions 44d.

As shown in FIG. 5, the lid 44c is provided so as to face the upper end of the beverage container C, and for example, closes a part of the opening C2 at the upper end of the beverage container C. The lid 44c is made of, for example, plastic and has a circular shape along the opening C2. As an example, the lid 44c has a pair of perforated portions 44g, and the pair of perforated portions 44g are formed at positions symmetrical with respect to the center 44f of the lid 44c. As a specific example, each perforated portion 44g is formed by a string 44h and an arc 44j of a lid 44c having a circular shape.

The number of the perforated portions 44g may be one or two or more, but more preferably two or more from the viewpoint that the liquid 2 and the foam 3 can be smoothly discharged. Further, the shape of the perforated portion 44g may be a shape having the strings 44h and the arc 44j as described above, or may be a shape different from the shape having the strings 44h and the arc 44j. However, the shape of the perforated portion 44 g is more preferably a half-moon shape from the viewpoint of being able to more accurately reproduce the state of the mouth of the drinker.

By covering the beverage container C with the lid 44c, it is possible to prevent a large amount of foam 3 from flowing out from the beverage container C. Further, normally, when drinking the effervescent beverage 1, the effervescent beverage 1 is drunk by suppressing the foam 3 with the upper lip, but the upper lip of the drinker can be reproduced on the string 44h portion of the lid 44c. Therefore, by reproducing the upper lip on the portion of the string 44h, it is possible to reproduce the state in which the effervescent beverage 1 is drunk in the mouth of the drinker. The pair of perforated portions 44g are directed to the depth direction and the front direction of the paper surface of FIG. 3, respectively. Since the state in which the effervescent beverage 1 is drunk in the mouth of the drinker can be more accurately reproduced by providing the lid 44c, it is more preferable to attach the lid 44c to measure the foam 3.

As shown in FIG. 3, a bubble measuring section 50 is provided on the other side of the two wall sections 44d. The foam measuring unit 50 is, for example, a ruler attached to the wall portion 44d, and it is possible to grasp the thickness of the foam 3 at a glance by looking at the foam measuring unit 50. The bubble measuring unit 50 is a portion capable of measuring the size and shape of the bubble 3. The bubble measuring unit 50 may be something other than a ruler attached to the wall unit 44d. That is, the foam measuring unit 50 may be a ruler that is manually applied to the beverage container C, or an image processing device that photographs and image-processes the foam 3 of the beverage container C to measure the size and shape of the foam 3. May include.

Next, the foam measurement method according to the present embodiment will be described with reference to FIG. 6 and the like. FIG. 6 is a flowchart showing an example of each step of the bubble measuring method according to the present embodiment. First, a closed container M filled with the effervescent beverage 1 is installed in the drilling machine 20 (step S1). Specifically, as shown in FIG. 2, the closed container M is placed upside down on the table 23, and the closed container M is pressed from above and below by pulling the lever 21b to rotate the lever 21b. And fix the vertical position of the closed container M.

A hole is made in the closed container M with the vertical position of the closed container M fixed (step S2). At this time, by holding the grip portion 26a by hand and lowering the rod-shaped portion 26, the rod-shaped portion 26 is pierced into the closed container M to make a hole in the closed container M. The effervescent beverage 1 inside the closed container M is pumped to the server 30 through the rod-shaped portion 26 and the flow path F1 (step of pumping the effervescent beverage).

Next, the effervescent beverage 1 is poured from the server 30 into the beverage container C (step S3, step of pouring foam). Specifically, by holding the beverage container C with one hand, arranging the beverage container C under the liquid dispensing portion 33b, and pulling the lever 33a with the beverage container C tilted, the liquid is inside the beverage container C. 2 is poured out in a fixed amount (for example, 60% or more and 80% or less of the capacity of the beverage container C). Then, by pushing the lever 33a with the inclination of the beverage container C approaching vertically, a certain amount of foam 3 is poured onto the liquid 2 (for example, until the foam 3 reaches the upper end of the beverage container C). At this time, the volume ratio of the liquid 2 and the foam 3 is, for example, about 7: 3.

Subsequently, as shown in FIGS. 3 and 4A, the beverage container C is installed in the tilting device 40 (step S4). At this time, the beverage container C is placed on the table 44a along the horizontal plane H, and the lid 44c is installed on the beverage container C. Then, after the first time has elapsed since the foam 3 was poured out, the beverage container C is tilted (step S5, the step of tilting the beverage container) as shown in FIG. 4 (b). The first time is a time assuming a time from the time when the effervescent beverage 1 is poured into the beverage container C until the effervescent beverage 1 is drunk, and is, for example, 10 seconds or more and 300 seconds or less. The first time may be 10 seconds or more and 180 seconds or less. In this case, it is possible to more faithfully reproduce the time from when the effervescent beverage 1 is poured out until it is drunk. Further, as an example, the first time may be 60 seconds. Further, the angle θ of the bottom portion C1 of the beverage container C with respect to the horizontal plane H is, for example, 10 ° or more and 80 ° or less. This angle θ is an angle assuming an angle at which the beverage container C is tilted when the effervescent beverage 1 is drunk. As an example, the angle θ may be 65 °.

When the beverage container C is tilted, the effervescent beverage 1 is poured out from the beverage container C, and the poured effervescent beverage 1 is stored in a storage container such as a bucket. After the second time has elapsed from tilting the beverage container C, the tilted beverage container C is returned to its original position (step S6, step of returning the beverage container) as shown in FIG. 4 (c). The second time is a time assuming the time from the tilting of the beverage container C to the return of the beverage container C, and is, for example, 1 second or more and 10 seconds or less. As an example, the second time may be 2 seconds.

Immediately after the beverage container C is returned to its original position, as shown in FIG. 7A, the frosty mist 4 extends downward from the foam 3, and the regions of the frosty mist 4 and the foam 3 gradually rise. After that, as shown in FIG. 7B, the frosty mist 4 is regenerated as the foam 3 to thicken the foam 3, the regions of the foam 3 and the frosty mist 4 increase, and the region of the frosty mist 4 becomes smaller. Then, as shown in FIG. 7 (c), the regeneration of the foam 3 further progresses, and the thickness of the foam 3 and the liquid 2 becomes constant in a state where the foam 3 becomes thicker.

After the thicknesses of the foam 3 and the liquid 2 become constant as described above, the foam measuring unit 50 executes the measurement of the foam 3 (step S7). For example, as shown in FIG. 3, the thickness of the foam 3 is measured by looking at the foam measuring unit 50 attached to the tilting device 40, and the measured thickness of the foam 3 and the thickness of the foam 3 before tilting are determined. The regenerated amount of the foam 3 is measured by comparison (step of measuring the regenerated amount of the foam). In this way, a series of steps is completed after the measurement of the bubble 3 is completed.

Next, the foam measuring method and the action and effect obtained from the foam measuring device 10 according to the present embodiment will be described in detail. In the foam measuring method according to the present embodiment, as shown in FIGS. 4 (a) to 4 (c), the first time after pouring the liquid 2 and the foam 3 of the effervescent beverage 1 into the beverage container C After that, the beverage container C is tilted. Thereby, by setting the time from the injection of the effervescent beverage 1 to the drinking as the first hour, the state from the actual injection of the effervescent beverage 1 to the drinking is simulated. Can be done.

Further, after the second time has elapsed from tilting the beverage container C, the inclination of the beverage container C is restored, and the amount of foam 3 generated when the beverage container C is returned is measured. Therefore, by setting the time for drinking by tilting the beverage container C as the second hour, it is possible to measure the regeneration amount of the foam 3 after simulating the state from the time when the beverage container C is drunk until the beverage container C is returned to its original state. can. Therefore, by measuring the amount of foam 3 after simulating the actual drinking of the effervescent beverage 1, the regenerated amount of foam 3 can be measured stably and accurately. As a result, it is possible to appropriately search for the regeneration conditions of the foam 3 after drinking. Here, the "amount of foam" includes the regenerated amount of foam 3 and the amount of foam 3 generated from the beginning in the beverage container C.

Further, the above-mentioned first time may be 10 seconds or more and 300 seconds or less. In this case, it is possible to more accurately simulate the time from when the effervescent beverage 1 is poured out until it is drunk. Therefore, the regenerated amount of the fine bubbles 3 can be measured more accurately. Specifically, since the first time from pouring to tilting is 10 seconds or more, the beverage container C can be tilted in a state where the frosty mist 4 is surely generated. Further, when the first time is 300 seconds or less, the possibility that the frosty mist 4 disappears before the beverage container C is tilted can be suppressed.

Further, in the step of tilting the beverage container C, the beverage container C may be tilted so that the angle θ of the bottom portion C1 of the beverage container C with respect to the horizontal plane H is 10 ° or more and 80 ° or less. In this case, the inclination of the beverage container C during drinking can be simulated more accurately. Therefore, the regenerated amount of the fine bubbles 3 can be measured more accurately.

Further, the effervescent beverage 1 may be packed in a closed container M before being poured out from the server 30. Then, in the step of pouring out, the liquid 2 and the foam 3 of the effervescent drink 1 are poured out from the server 30 for pouring out the effervescent drink 1, and the effervescent drink 1 is packed in a container before the step of pouring out. A step of forming a hole in the closed container M and pumping the effervescent beverage 1 from the closed container M to the server 30 may be provided. In this case, in order to make a hole in the closed container M in which the effervescent beverage 1 is packed and pump the effervescent beverage 1 to the server 30, measure the regenerated amount of the foam 3 in the effervescent beverage 1 packed in the container. Can be done. That is, since the regenerated amount of the foam 3 can be measured even for the effervescent beverage 1 packed in a container, it can be a highly versatile foam measuring method.

In particular, conventionally, when a closed container M such as a can or a bottle is opened, the pressure is released from the closed container M, so that the frosty mist 4 cannot be generated. However, in the present embodiment, the closed container M is installed in the drilling machine 20, and the effervescent beverage 1 in the closed container M is poured out from the server 30 connected to the drilling machine 20. Therefore, even when the effervescent beverage 1 is poured out from the closed container M such as a can or a bottle, the frosty mist 4 can be generated and the regenerated amount of the foam 3 can be measured.

The foam measuring device 10 according to the present embodiment can simulate a state in which the foaming beverage 1 is drunk by tilting the beverage container C into which the foaming beverage 1 is poured from the server 30 with the tilting device 40. .. Further, by returning the beverage container C tilted by the tilting device 40 to its original position, it is possible to simulate the state from the time when the beverage is drunk until the beverage container C is returned to its original position. By measuring the foam 3 by the foam measuring unit 50 when the beverage container C is returned, the regenerated amount of the foam 3 can be measured. Therefore, since the regenerated amount of the foam 3 can be measured after simulating the actual drinking of the effervescent beverage 1, the regenerated amount of the foam 3 can be measured stably and accurately.

Further, in the foam measuring method and the foam measuring device 10 according to the present embodiment, not only the regenerated amount of the foam 3 but also other characteristics of the foam 3 are timely measured with respect to the beverage container C after being tilted and restored. can do. It is also possible to measure the amount of foam 3 immediately after pouring into the beverage container C. For example, the beverage container C of the tilting device 40 may be tilted a plurality of times. That is, it is also possible to measure the amount of foam 3 when the beverage container C is tilted a plurality of times.

Further, the foam measuring device 10 may include a lid 44c which is mounted on the beverage container C and has a perforated portion 44g from which the liquid 2 and the foam 3 are discharged. In this case, by providing the lid 44c attached to the beverage container C, the liquid 2 and the foam 3 can be discharged from the perforated portion 44g of the lid 44c. With the perforated portion 44g of the lid 44c, it is possible to reproduce the state in which the effervescent beverage 1 is drunk in the mouth of the drinker. Therefore, since the beverage container C can be tilted under conditions closer to the actual drinking, the regenerated amount of the fine foam 3 can be measured more accurately.

Further, the foam measuring device 10 is connected to the server 30 and includes a drilling machine 20 for punching a hole in the closed container M, and the effervescent beverage 1 inside the closed container M is pumped from the drilling machine 20 to the server 30. And may be poured into the beverage container C. In this case, since the drilling machine 20 makes a hole in the closed container M and pumps the effervescent beverage 1 to the server 30, the regenerated amount of the foam 3 of the effervescent beverage 1 packed in the container can be measured. That is, since the regenerated amount of the foam 3 can be measured with respect to the effervescent beverage 1 packed in the container, the foam measuring device 10 with higher versatility can be obtained.

Although the foam measuring method and the embodiment of the foam measuring device according to the present invention have been described above, the present invention is not limited to the above-described embodiment and is modified to the extent that the gist described in each claim is not changed.
