Description

  The present invention relates to a foam measuring method and a foam measuring device for measuring foam of a sparkling beverage.

  Conventionally, various types of foam measuring methods and foam measuring apparatuses for measuring foam of a sparkling beverage are known. Japanese Patent Application Laid-Open No. 6-167373 describes an automatic foaming measurement method and an automatic foaming measurement apparatus. The automatic foam measurement apparatus includes a CCD camera that photographs the liquid level of beer poured into each of five graduated cylinders from above, and an image processing device that captures image information captured by the CCD camera. The image processing apparatus 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 apparatus, and the personal computer calculates the bubble retention time from the area of the liquid surface portion.

  Japanese Patent Application Laid-Open No. 2000-180358 describes a foam evaluation apparatus for evaluating the foam retention of beer. The foam evaluation apparatus includes a sensor that is positioned 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-described foam evaluation apparatus determines that there is foam in a region where light reflectance is high and that there is no foam in a region where light reflectance is low, and evaluates the foam retention of beer.

JP-A-6-167373 JP 2000-180358 A

  The above-described automatic measurement apparatus for foam evaluation evaluates foam retention based on image information, and the above-described foam evaluation apparatus evaluates foam retention based on the reflectance of light. By the way, the fine foam generated on the liquid of the sparkling beverage functions as a lid that makes the appearance good before drinking and the mouth feel good at the time of drinking, and prevents the escape of carbon dioxide and aroma. Furthermore, the fine foam has a function of preventing oxidation of the sparkling beverage due to contact with air.

  Fine foam is generated not only when the sparkling beverage is dispensed, but also when the sparkling beverage is consumed. A fine granular foam layer called frosty mist is generated at the boundary between the liquid and foam of the sparkling beverage, and fine foam is regenerated by stimulating the frosty mist during drinking. When a large amount of frosty mist is produced, it is considered that many fine bubbles are regenerated. Therefore, it is important to measure the amount of fine bubbles regenerated. Accordingly, in providing a sparkling beverage having a good appearance and mouthfeel and further having the above-mentioned foams that perform various functions, it is required to be able to measure fine foam characteristics.

  An object of this invention is to provide the foam measuring method and foam measuring apparatus which can measure the characteristic of a fine bubble.

  The foam measuring method according to one aspect of the present invention is a foam measuring method for measuring foam in an effervescent beverage, the step of pouring the liquid and foam of an effervescent beverage into a beverage container, and the foam being dispensed The step of tilting the beverage container after the first time has elapsed, the step of returning the tilted beverage container after the second time has elapsed since the tilt of the beverage container, and the amount of foam generated inside the returned beverage container Measuring.

  In this foam measurement method, the beverage container is tilted after the first time has elapsed since the liquid and foam of the sparkling beverage were poured into the beverage container. Thereby, by setting the time from when the sparkling beverage is poured out until it is drunk to the first time, it is possible to simulate the state from when the sparkling beverage is actually poured out until it is drunk. . In addition, after the second time has elapsed after the beverage container is tilted, the tilt of the beverage container is returned to the original, and the amount of foam generated when the beverage container is returned is measured. Therefore, the amount of regeneration of the foam can be measured after simulating the state from when the beverage container is returned to its original state by setting the time for drinking while tilting the beverage container to be the second time. Therefore, the amount of foam regeneration can be measured stably and accurately by simulating actual drinking of sparkling beverages and measuring the amount of foam. As a result, conditions for regenerating foam after drinking can be sought appropriately. Furthermore, not only the amount of foam regeneration, but also other properties of the foam can be measured in a timely manner.

  Further, the first time described above may be not less than 10 seconds and not more than 300 seconds. In this case, the time from when the sparkling beverage is poured out until it is drunk can be more accurately reproduced. Therefore, the amount of fine bubbles regenerated can be measured more accurately.

  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 at the time of drinking can be simulated more accurately. Therefore, it is possible to measure the amount of fine bubbles regenerated more accurately.

  Also, in the pouring process, the liquid and foam of the sparkling beverage are poured out from the server for pouring sparkling beverage, and before the pouring step, a hole is opened in the sealed container filled with the sparkling beverage. And a step of pumping the sparkling beverage from the sealed container to the server. In this case, since a hole is opened in the sealed container packed with the sparkling beverage and the sparkling beverage is pumped to the server, the amount of foam regeneration of the sparkling beverage packed in the container can be measured. That is, since the amount of foam regeneration can also be measured for a sparkling beverage packed in a container, a highly versatile foam measuring method can be obtained.

  A foam measuring device according to one aspect of the present invention is a foam measuring device for measuring foam in a sparkling beverage, a server for pouring the liquid and foam of a sparkling beverage into a beverage container, and the liquid and foam being poured. A tilting device that tilts the beverage container that has been removed; and a foam measuring unit that measures foam generated inside the beverage container by being tilted and returned by the tilting device.

  This foam measuring device can simulate a state in which an effervescent beverage is drunk by tilting a beverage container into which an effervescent beverage is poured out from a server with an inclination device. Further, by returning the beverage container tilted by the tilting device, it is possible to simulate a state from when the beverage container is drunk to when the beverage container is returned to the original state. By measuring the foam by the foam measuring unit when the beverage container is returned, the amount of foam regeneration can be measured. Therefore, since the amount of foam regeneration can be measured after simulating actual drinking of sparkling beverages, the amount of foam regeneration can be measured stably and accurately. Furthermore, with this foam measuring device, not only the amount of foam regeneration but also other characteristics of the foam can be measured in a timely manner with respect to the beverage container after being tilted and restored.

  Moreover, the foam measuring device described above may be provided with a lid that is attached to a beverage container and has a hole for discharging liquid and foam. In this case, by providing a lid attached to the beverage container, the liquid and foam can be discharged from the hole opening portion of the lid. The state where the sparkling beverage is drunk in the mouth of the drinker can be reproduced by the opening portion of the lid. Therefore, since the beverage container can be tilted under conditions closer to actual drinking, the amount of fine foam regeneration can be measured more accurately.

  In addition, the sparkling beverage may be packed in a sealed container before being poured out from the server. In this case, since foam can be measured even for a sparkling beverage packed in a container, a highly versatile foam measuring device can be obtained.

  In addition, the above-described foam measuring device is provided with a punching machine that is connected to a server and opens a hole in the sealed container, and the sparkling beverage inside the sealed container is pumped from the punching machine to the server and poured into the beverage container. May be issued. In this case, since the punching machine makes a hole in the sealed container and pumps the sparkling beverage to the server, the amount of foam regeneration of the sparkling beverage packed in the container can be measured. That is, since the amount of foam regeneration can be measured even for a sparkling beverage packed in a container, the foam measuring device can be made more versatile.

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

  Hereinafter, embodiments of a foam measuring method and a foam measuring apparatus 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 denoted by the same reference numerals, and repeated description is omitted as appropriate. In addition, the drawings are drawn in a simplified or exaggerated manner for easy understanding, and dimensions and the like are not limited to those described in the drawings.

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

  The sparkling beverage 1 includes, for example, a gas-containing fermented liquor such as carbon dioxide gas, and is formed with foaming characteristics 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 the foam retention characteristic that the foam 3 is kept for a certain time or more. Specifically, the sparkling beverage 1 is, for example, a beverage having an 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 characteristics of a beverage.

  The sparkling beverage 1 may be a beer-taste beverage. Beer-taste beverages include beverages that have a taste like beer and beverages that give drinkers the feeling 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, beer-taste beverages are malt fermented beverages such as beer using malt as a raw material, sparkling liquor, non-alcoholic beer, and liqueur (for example, beverages classified as “liqueur (foamable) (1)” under the liquor tax law). , And beer-taste malt beverages that do not use wheat or malt as a raw material (for example, beverages classified as “other brewed liquors (foaming) (1)” under the liquor tax law). The sparkling beverage 1 may be a sparkling beverage that is not a beer-taste beverage. Hereinafter, an example in which the sparkling beverage 1 is beer will be described.

  The foam 3 of the sparkling beverage 1 is a so-called fine foam and 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 sparkling beverage 1, and moreover serves as a lid that prevents the liquid 2 from scenting or carbon dioxide, and the liquid 2 from being oxidized. Preferably it is produced. Fine bubbles are also generated from the frosty mist 4 that appears at the boundary between the liquid 2 and the bubbles 3.

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

  As shown in FIGS. 2 and 3, the foam measuring apparatus 10 according to the present embodiment includes, for example, a punching machine 20 that opens a hole in a sealed container M filled with the sparkling beverage 1, and the sparkling beverage 1. A server 30 to be dispensed, a tilting device 40 for tilting the beverage container C containing the sparkling beverage 1, and a foam measuring unit 50 for measuring the foam 3 of the sparkling beverage 1 are provided. The hermetic container M indicates a container in which the sparkling beverage 1 is packed and may be a can filled with the sparkling beverage 1 or a bottle filled with the sparkling beverage 1. . Moreover, the container filling has shown the state by which containers, such as a can or a bottle, were filled and sealed with the sparkling beverage.

  As shown in FIG. 2, the punching machine 20 includes, for example, a base 21, a support column 22 that extends upward from the base 21, a table 23 that is positioned on the base 21, and a pressing unit 24 that holds the sealed container M, A holding part 25 provided above the holding part 24, a rod-like part 26 passed through the holding part 25 and the holding part 24, and a carbon dioxide gas cylinder 27 are provided. The base 21 has, for example, a rectangular parallelepiped shape, and includes a lever 21b that is rotatable on the side surface 21a. As an example, when the lever 21b is pulled and the lever 21b is rotated, the base 23 protrudes upward from the base 21 and the hermetic container M is pressed under the pressing portion 24.

  A supporting part 24 and a gripping part 25 are supported on the column 22, and the position of the pressing unit 24 can be changed in the vertical direction with respect to the column 22. A closed container M filled with the sparkling 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 that is a can is placed on the table 23 in an upside down state.

  The rod-shaped portion 26 has a gripping portion 26a at the upper end thereof, and can move up and down by having the gripping portion 26a. The rod-shaped part 26 is a part that opens a hole in the sealed container M placed between the base 23 and the pressing part 24, and the hole is opened in the sealed container M by moving downward. A channel F1 through which the sparkling beverage 1 in the sealed container M circulates extends from the grip portion 26a.

  The carbon dioxide gas cylinder 27 supplies carbon dioxide gas to the sparkling beverage 1 and pumps the sparkling 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 through the flow path F2, the holding part 24, and the rod-shaped part 26, and the flow path F1 connects the punching machine 20 and the server 30 to each other. Therefore, the sparkling beverage 1 inside the sealed container M is pumped by the carbon dioxide gas from the carbon dioxide cylinder 27 from the sealed container M having a hole to the server 30 through the rod-shaped portion 26 and the flow path F1.

  The server 30 is, for example, a beverage server that dispenses the sparkling beverage 1. The server 30 includes a base 31, a columnar part 32 through which the sparkling beverage 1 circulates, and a currant 33 branched from the columnar part 32. For example, the columnar portion 32 extends upward from the base 31, and the currant 33 protrudes from the side surface 32 a of the columnar portion 32. The currant 33 includes a lever 33a that is swung by hand, a liquid dispensing portion 33b that pours liquid 2 according to the rocking operation of the lever 33a, and a bubble 3 that is poured according to the rocking operation of the lever 33a. And a foam pouring part 33c for dispensing. For example, in a state where the beverage container C is disposed under the liquid pouring part 33b and the foam pouring part 33c, pulling the lever 33a (swinging the lever 33a on the right side in FIG. 2) causes the drink from the liquid pouring part 33b. Liquid 2 is poured into the container C. When the lever 33a is pushed (the lever 33a is swung to the left in FIG. 2), the foam 3 is poured out from the foam dispensing section 33c into 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 the base 41, a pair of support portions 42 extending upward from the base 41, a rotation portion 43 that is rotatable with respect to each support portion 42, and the beverage container C. And a container rotating part 44 that rotates together with the part 43. The support portion 42 includes a pair of support columns 42a extending upward from the base 41 and a support body 42b supported by the support columns 42a. A rotation portion 43 is inserted in each support body 42b in the horizontal direction.

  The rotating portion 43 extends in the horizontal direction between the pair of support bodies 42b, and includes a motor 43a and a control section 43b outside the pair of support bodies 42b. The motor 43a generates a rotational driving force that rotates the container rotating unit 44 about the rotating unit 43, and the control unit 43b controls the motor 43a. As shown in FIG. 3 and FIG. 4B, the beverage container C rotates together with the container rotating unit 44 around the rotating unit 43. In the control unit 43b, for example, the angle θ of the bottom C1 of the beverage container C with respect to the horizontal plane H, the time until it rotates to the angle θ, the time for maintaining the angle θ, and the like can be set. The controller 43b controls the motor 43a so that the beverage container C is inclined at the set angle θ and time.

  The container rotation unit 44 includes a table 44a on which the beverage container C is placed, a connection unit 44b that connects the table 44a and the rotation unit 43 to each other, and a lid that extends upward from the connection unit 44b and covers the upper end of the beverage container C. 44c. In FIG. 4A to FIG. 4C, a part of the container rotating unit 44 is not shown. The connecting portion 44b includes a pair of wall portions 44d extending upward from the left and right ends of the base 44a, and the beverage container C is placed between the pair of wall portions 44d. The base 44 a and the pair of wall portions 44 d 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 44 c is provided so as to face the upper end of the beverage container C and, for example, closes a part of the opening C <b> 2 at the upper end of the beverage container C. The lid 44c is made of plastic, for example, and has a circular shape along the opening C2. As an example, the lid 44c has a pair of hole portions 44g, and the pair of hole portions 44g are formed at positions symmetrical to each other with respect to the center 44f of the lid 44c. As a specific example, each hole 44g is formed by a string 44h and an arc 44j of a lid 44c having a circular shape.

  In addition, although the number of the perforated parts 44g may be one, or two or more, it is more preferably two or more from the viewpoint that the liquid 2 and the bubbles 3 can be discharged smoothly. The shape of the hole 44g may be a shape having the string 44h and the arc 44j as described above, or may be a shape different from the shape having the string 44h and the arc 44j. However, the shape of the perforated portion 44g is more preferably a half-moon shape from the viewpoint of more accurately reproducing the state of the drinker's mouth.

  By covering the beverage container C with the lid 44c, it is possible to prevent the foam 3 from flowing out of the beverage container C in large quantities. Normally, when drinking the sparkling beverage 1, the sparkling beverage 1 is drunk while suppressing the foam 3 with the upper lip, but the upper lip of the drinker can be reproduced in the portion of the string 44h of the lid 44c. Therefore, by reproducing the upper lip in the portion of the string 44h, it is possible to reproduce the state in which the sparkling beverage 1 is drunk in the drinker's mouth. Note that the pair of perforated portions 44g are directed in the depth direction and the front direction of the paper surface of FIG. Since the state in which the sparkling 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 measure the foam 3 by attaching the lid 44c.

  As shown in FIG. 3, a bubble measuring unit 50 is provided on the other of the two wall portions 44d. The bubble measuring unit 50 is, for example, a ruler affixed to the wall 44d, and the thickness of the bubble 3 can be grasped at a glance by looking at the bubble measuring unit 50. The bubble measuring unit 50 is a part capable of measuring the size and shape of the bubble 3. The bubble measuring unit 50 may be other than a ruler attached to the wall 44d. That is, the bubble measuring unit 50 may be a ruler applied to the beverage container C by hand, or an image processing device that measures the size and shape of the bubbles 3 by photographing and image processing the bubbles 3 of the beverage container C. May be included.

  Next, the bubble measuring method according to the present embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing an example of each step of the foam measuring method according to the present embodiment. First, the hermetic container M filled with the sparkling beverage 1 is installed in the punching machine 20 (step S1). Specifically, as shown in FIG. 2, the sealed container M that is turned upside down is placed on the table 23, and the lever 21 b is pulled to rotate the lever 21 b, thereby pressing the sealed container M from above and below. The upper and lower positions of the sealed container M are fixed.

  A hole is opened in the sealed container M in a state where the vertical position of the sealed container M is fixed (step S2). At this time, by holding the gripping part 26a by hand and lowering the bar-shaped part 26, the bar-shaped part 26 is pierced into the sealed container M to make a hole in the sealed container M. The sparkling beverage 1 inside the sealed container M is pumped to the server 30 through the rod-shaped portion 26 and the flow path F1 (step of pumping sparkling beverage).

  Next, the sparkling beverage 1 is poured out from the server 30 into the beverage container C (step S3, a step of pouring foam). Specifically, holding the beverage container C with one hand, placing the beverage container C under the liquid dispensing portion 33b, and pulling the lever 33a while the beverage container C is tilted, the liquid is put inside the beverage container C. 2 is dispensed in a certain amount (for example, 60% or more and 80% or less of the capacity of the beverage container C). Then, 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) by pushing the lever 33a with the inclination of the beverage container C approaching vertical. At this time, the ratio of the volume of the liquid 2 to the bubble 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 44 a along the horizontal plane H, and the lid 44 c is installed on the beverage container C. Then, after the first time has elapsed since the bubble 3 was poured out, the beverage container C is tilted as shown in FIG. 4B (step S5, step of tilting the beverage container). The first time is a time assuming a time from when the sparkling beverage 1 is poured into the beverage container C until the sparkling beverage 1 is drunk, and is, for example, not less than 10 seconds and not more than 300 seconds. 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 sparkling beverage 1 is poured out until it is drunk. Further, as an example, the first time may be 60 seconds. Moreover, the angle θ of the bottom C1 of the beverage container C with respect to the horizontal plane H is, for example, not less than 10 ° and not more than 80 °. This angle θ is an angle assuming an angle at which the beverage container C is tilted when the sparkling beverage 1 is drunk. As an example, the angle θ may be 65 °.

  When the beverage container C is tilted, the sparkling beverage 1 is poured out from the beverage container C, and the poured sparkling beverage 1 is stored in a storage container such as a bucket. After the second time has elapsed since the beverage container C is tilted, the tilted beverage container C is returned to its original position as shown in FIG. 4C (step S6, step of returning the beverage container). The second time is a time assuming a time until the beverage container C is returned after being tilted, 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 returning the beverage container C, the frosty mist 4 extends downward from the foam 3 as shown in FIG. 7A, and the areas of the frosting mist 4 and the foam 3 gradually rise. Thereafter, as shown in FIG. 7 (b), the frosty mist 4 is regenerated as the bubble 3 to increase the thickness of the bubble 3, and the region of the bubble 3 and frosty mist 4 rises and the region of the frosty mist 4 becomes smaller. And as FIG.7 (c) shows, the reproduction | regeneration of the bubble 3 further progresses, and the thickness of the bubble 3 and the liquid 2 becomes constant in the state in which the bubble 3 became thicker.

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

  Next, the effect obtained from the foam measuring method and the foam measuring apparatus 10 according to the present embodiment will be described in detail. As shown in FIGS. 4A to 4C, the foam measuring method according to the present embodiment has a first time after pouring the liquid 2 and foam 3 of the sparkling beverage 1 into the beverage container C. After the elapse, the beverage container C is tilted. By simulating the state from when the sparkling beverage 1 is actually dispensed until it is drunk by setting the time from when the sparkling beverage 1 is dispensed to when it is consumed as the first time. Can do.

  In addition, after the second time has elapsed since the beverage container C is tilted, the tilt of the beverage container C is returned to the original, and the amount of foam 3 generated when the beverage container C is returned is measured. Therefore, the amount of regenerating foam 3 can be measured after simulating the state from when the beverage container C is returned to its original state by setting the time for inclining the beverage container C to be the second time. it can. Therefore, by measuring the amount of the foam 3 after simulating actual drinking of the sparkling beverage 1, the regeneration amount of the foam 3 can be measured stably and accurately. As a result, it is possible to appropriately search for the regeneration conditions for the foam 3 after drinking. Here, the “amount of foam” includes the amount of foam 3 regenerated and the amount of foam 3 generated in the beverage container C from the beginning.

  Further, the first time described above may be not less than 10 seconds and not more than 300 seconds. In this case, it is possible to more accurately simulate the time from when the sparkling beverage 1 is poured out until it is consumed. Therefore, the amount of fine bubbles 3 regenerated can be measured more accurately. Specifically, the beverage container C can be tilted in a state in which the frosting mist 4 is reliably generated, because the first time from the dispensing to the tilting is 10 seconds or more. Moreover, since the first time is 300 seconds or less, the possibility that the frosting mist 4 disappears before the beverage container C is tilted can be suppressed.

  In the step of tilting the beverage container C, the beverage container C may be tilted so that the angle θ of the bottom 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 amount of fine bubbles 3 regenerated can be measured more accurately.

  In addition, the sparkling beverage 1 may be packed in a sealed container M before being poured out from the server 30. And in the process to pour out, the liquid 2 and foam 3 of the sparkling beverage 1 are poured out from the server 30 that pours the sparkling beverage 1, and the sparkling beverage 1 is packed in a container before the step of pouring out. You may provide the process of punching the airtight container M and pumping the sparkling beverage 1 from the airtight container M to the server 30. In this case, in order to open a hole in the sealed container M in which the sparkling beverage 1 is packed and to pump the sparkling beverage 1 to the server 30, the amount of foam 3 of the sparkling beverage 1 packed in the container is measured. Can do. That is, since the regeneration amount of the foam 3 can be measured even for the sparkling beverage 1 packed in a container, a highly versatile foam measuring method can be obtained.

  In particular, when the closed container M such as a can or a bottle is opened, the frosty mist 4 cannot be generated because the pressure is released from the closed container M. However, in this embodiment, the sealed container M is installed in the punching machine 20 and the sparkling beverage 1 in the sealed container M is poured out from the server 30 connected to the punching machine 20. Therefore, even when the sparkling 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 apparatus 10 according to the present embodiment can simulate the state in which the sparkling beverage 1 is drunk by tilting the beverage container C into which the sparkling beverage 1 is poured out from the server 30 with the tilting device 40. . In addition, by returning the beverage container C tilted by the tilting device 40, it is possible to simulate a state from when the beverage container C is returned to when the beverage container C is returned to its original state. By measuring the foam 3 by the foam measuring unit 50 when the beverage container C is returned, the amount of regeneration of the foam 3 can be measured. Therefore, since the amount of regeneration of the foam 3 can be measured after simulating actual drinking of the sparkling beverage 1, the amount of regeneration of the foam 3 can be measured stably and accurately.

  Furthermore, in the foam measuring method and the foam measuring apparatus 10 according to the present embodiment, not only the regenerated amount of the foam 3 but also other characteristics of the foam 3 are measured in a timely manner with respect to the beverage container C after being tilted and restored. can do. Moreover, the quantity of the foam 3 immediately after pouring into the drink container C can also be measured. For example, the tilt of the beverage container C of the tilting device 40 may be performed 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.

  Moreover, the foam measuring apparatus 10 may be provided with a lid 44c which is attached to the beverage container C and has a hole 44g through which the liquid 2 and 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 hole 44g of the lid 44c. The state where the sparkling beverage 1 is drunk in the mouth of the drinker can be reproduced by the holed portion 44g of the lid 44c. Therefore, since the beverage container C can be tilted under conditions closer to actual drinking, the amount of regeneration of the fine bubbles 3 can be measured more accurately.

  In addition, the foam measuring apparatus 10 includes a puncher 20 that is connected to the server 30 and opens a hole in the sealed container M, and the sparkling beverage 1 inside the sealed container M is pumped from the puncher 20 to the server 30. And may be poured out into the beverage container C. In this case, since the punching machine 20 opens a hole in the sealed container M and pumps the sparkling beverage 1 to the server 30, the regeneration amount of the foam 3 of the sparkling beverage 1 packed in the container can be measured. That is, since the regeneration amount of the foam 3 can be measured with respect to the sparkling beverage 1 packed in a container, the foam measuring device 10 can be made more versatile.

  As mentioned above, although the embodiment of the foam measuring method and the foam measuring apparatus according to the present invention has been described, the present invention is not limited to the above-described embodiment, and is modified within the scope not changing the gist described in each claim. Or may be applied to other things.

  For example, in the above-described embodiment, the drilling machine 20 including the base 21, the support column 22, the base 23, the pressing unit 24, the gripping unit 25, and the rod-shaped unit 26 has been described. However, the configuration of the drilling machine can be changed as appropriate. . The configurations of the server, the tilting device, and the foam measuring unit are not limited to the server 30, the tilting device 40, and the foam measuring unit 50 of the above-described embodiment, and can be changed as appropriate.

  Moreover, although the above-mentioned embodiment demonstrated the example in which the sparkling beverage 1 was pumped from the punching machine 20 to the server 30, the means to pump the sparkling beverage 1 can be changed suitably. Further, in the above-described embodiment, an example in which the hermetic container M is installed in the punching machine 20 and a hole is formed in the hermetic container M by the rod-shaped portion 26 and the sparkling beverage 1 is poured out from the server 30 has been described. However, instead of the punching machine 20 and the sealed container M packed in a container, the sparkling beverage may be poured out from a server connected to the barrel. Thus, when pouring the sparkling beverage contained in the barrel from the server 30, the punching machine 20 can be omitted, and the foam in the sparkling beverage from the barrel can be measured. It becomes possible.

  Moreover, although the above-mentioned embodiment demonstrated the example whose airtight container M is a can or a bottle, the kind of airtight container is not restricted to a can or a bottle. For example, the sealed container M may be a plastic bottle.

  Moreover, although the above-mentioned embodiment demonstrated the example which measures the reproduction | regeneration amount of the bubble 3, the bubble measuring apparatus which concerns on this invention is not restricted to the reproduced | regenerated bubble 3, It can measure the various characteristics of a bubble. Is possible. For example, it is also possible to measure time-series changes in the shape and size of the frosty mist itself with a bubble measuring device.

  Moreover, although the above-mentioned embodiment demonstrated the example which measures the foam 3 of the sparkling beverage 1 which is beer, the sparkling beverage may be beverages other than beer and the kind of sparkling beverage can be changed suitably. It is.
