Description

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

  Conventionally, various methods have been known as a foam measuring method and a foam measuring device for measuring foam of a sparkling beverage. Japanese Patent Application Laid-Open No. 6-167373 describes a method for automatically measuring foam and an automatic measuring device for foam. The bubble measuring automatic measuring apparatus includes a CCD camera for photographing from above the liquid level of the beer poured into each of the five measuring cylinders, and an image processing apparatus for taking in image information photographed by the CCD camera. The image processing apparatus performs binarization processing on image information, and detects a bubble portion as white and a liquid level 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 level portion.

  In Japanese Patent Application Laid-Open No. 2000-180358, a foamability evaluation device for evaluating the foamability of beer is described. The foam stability evaluation device includes a sensor positioned above the beer poured into the glass to measure the amount of light from the beer, and evaluates foam stability based on the amount of light measured by the sensor. Since the bubbles are white, the light reflectance is high, and the liquid level is not white, so the light reflectance is low. The above-described foam stability evaluation device determines that foam is present in a region where the light reflectance is high and does not foam in a region where the light reflectance is low, and evaluates the foam durability of beer.

Unexamined-Japanese-Patent No. 6-167373 JP 2000-180358 A

  In the above-described automatic apparatus for measuring the presence of bubbles, the foam stability is evaluated by image information, and in the apparatus for evaluating the presence of foam, the foam durability is evaluated by the light reflectance. By the way, the fine foam produced on the liquid of the sparkling beverage functions as a lid for preventing the appearance of carbon dioxide gas and aroma, as well as making the appearance good before drinking and the good feeling of mouth when drinking. Furthermore, the fine foam also has the function of preventing the oxidation of the sparkling beverage due to contact with air.

  Granular foam is not only produced upon pouring of the sparkling beverage, but also regenerated upon drinking of the sparkling beverage. At the boundary between the liquid and foam of the foamable beverage, a layer of fine granular cells called frosty mist is formed, and when the frosty mist is stimulated upon drinking, fine foam is regenerated. When a large amount of frosty mist is generated, it is considered that a large amount of fine bubbles is regenerated, so it is important to measure the amount of fine bubbles regenerated. Therefore, in providing a foamable beverage having a foam with good appearance and mouth feel and further performing the various functions described above, it is required to be able to measure the characteristics of the fine foam.

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

  The foam measurement method according to one aspect of the present invention is a foam measurement method for measuring foam in a sparkling beverage, comprising the steps of pouring out the liquid and foam of the sparkling beverage into the beverage container, and pouring the foam A step of tilting the beverage container after the first time has elapsed, a step of returning the tilted beverage container after the second time since the beverage container was tilted, and the amount of foam generated inside the returned beverage container Measuring.

  This foam measurement method tilts the beverage container after a first time has elapsed since pouring the liquid and foam of the foamable beverage into the beverage container. Thus, by setting the time from the pouring of the sparkling beverage to drinking it as the first time, it is possible to simulate the condition from the pouring of the sparkling beverage to the drinking. . Also, after the beverage container is tilted, the tilt of the beverage container is restored after the second time has elapsed, and the amount of foam generated when the beverage container is returned is measured. Therefore, the amount of regeneration of foam can be measured after simulating the state from drinking to the return of the beverage container by setting the time for tilting the beverage container and taking it for the second time. Therefore, by simulating the actual drinking of the sparkling beverage and measuring the amount of foam, the amount of regenerated foam can be stably and accurately measured. As a result, the foam regeneration conditions after drinking can be properly explored. Furthermore, it is possible to timely measure not only the amount of regenerated foam but also other properties of the foam.

  Further, the first time described above 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 until when it is consumed. Therefore, the amount of fine bubble regeneration can be measured more accurately.

  In the step of inclining the beverage container, the beverage container may be inclined such that the angle of the bottom of the beverage container with respect to the horizontal surface 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, the amount of fine bubble regeneration can be measured more accurately.

  In addition, in the step of pouring out, the foamable beverage is pierced in the closed container filled with the foamable beverage prior to the step of pouring out the liquid and foam of the sparkling beverage from the server which pours out the sparkling beverage. It may comprise the step of pumping the sparkling beverage from the closed container to the server. In this case, a hole is formed in the closed container in which the effervescent beverage is packed and the effervescent beverage is pumped to the server, so that the amount of regenerated foam of the packaged effervescent beverage can be measured. That is, since the regenerated amount of foam can be measured also for the container-packed sparkling beverage, a versatile foam measuring method can be obtained.

  The foam measuring device according to one aspect of the present invention is a foam measuring device for measuring foam in a sparkling beverage, which comprises a server for pouring the liquid and foam of the sparkling beverage into the beverage container, the liquid and the foam The apparatus comprises: an inclination device for inclining the discharged beverage container; and a foam measuring unit that measures bubbles generated inside the beverage container by being returned by being inclined by the inclination device.

  The foam measuring device can simulate the drinking condition of the foamable beverage by tilting the beverage container from which the foamable beverage has been dispensed from the server with the tilt device. In addition, by returning the beverage container tilted by the tilting device, it is possible to simulate a condition from drinking until the beverage container is returned. The amount of regenerated foam can be measured by measuring the foam by means of the foam measuring unit when the beverage container is returned. Therefore, since it is possible to measure the amount of regenerated foam after simulating the actual drinking of the sparkling beverage, it is possible to stably and accurately measure the regenerated amount of foam. Furthermore, with this foam measuring device, it is possible to timely measure not only the regenerated amount of foam but also other characteristics of the foam, with respect to the beverage container after being tilted back.

  Also, the above-described foam measuring device may be provided with a lid that 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 is possible to discharge liquid and foam from the perforated portion of the lid. The perforated portion of the lid can reproduce the state in which the sparkling beverage is ingested into the mouth of the drinker. Therefore, since the beverage container can be tilted under conditions closer to actual drinking, it is possible to more accurately measure the amount of fine foam regeneration.

  Also, the sparkling beverage may be packaged in a closed container prior to being dispensed from the server. In this case, since measurement of foam can be performed also for the container-packed sparkling beverage, a versatile foam measuring apparatus can be obtained.

  In addition, the above-mentioned foam measuring device is provided with a drilling machine connected to the server and drilling a hole in the closed container, and the foamable beverage inside the closed container is pumped from the drilling machine to the server and poured into the beverage container. It may be issued. In this case, the amount of regenerated foam in the containerized foamable beverage can be measured because the puncher punctures the closed container and pumps the foamable beverage to the server. That is, since the regenerated amount of foam can be measured also for the container-packed sparkling beverage, it is possible to make the foam measuring device more versatile.

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

  Hereinafter, embodiments of a foam measurement method and a foam measurement 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 will be denoted by the same reference symbols, and overlapping descriptions will be omitted as appropriate. In addition, the drawings are drawn in a simplified or exaggerated manner for ease of understanding, and the dimensions and the like are not limited to those described in the drawings.

  FIG. 1 is a view showing an example of a foamable 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 in the interior of the beverage container C, the liquid 2 and the foam 3 located above the liquid 2 are provided. The beverage container C is, for example, a container capable of containing the sparkling beverage 1 such as a mug, a glass, or a cup.

  The effervescent beverage 1 contains, for example, a fermented liquor containing a gas such as carbon dioxide gas, and the effervescent property is such that a layer of foam 3 is formed on the liquid 2 when poured into the beverage container C, It is a beverage having a lathering property in which the lather 3 is kept for a predetermined time or more. Specifically, the effervescent drink 1 is, for example, a drink showing an NIBEM value of 50 seconds or more according to the EBC (European Brewery Convention) method. The NIBEM value is an index value that indicates the lather characteristics of the beverage.

  The sparkling beverage 1 may be a beer-taste beverage. Beer-taste beverages include beverages that have a beer-like taste and beverages that give the drinker a sense of drinking a beer. Beer-taste beverages having an alcohol content of 1% or more are also referred to as beer-taste alcoholic beverages. Furthermore, beer-taste beverages include malt-fermented beverages such as beer, low-malt beer, non-alcohol beer, liqueur (eg, beverage classified as "liqueur (foamable) (1)" according to the liquor tax method) using malt as a raw material And a beer-taste malt beverage which does not use wheat or malt as a raw material (for example, a beverage classified into “other brewed liquor (foamable) (1)”) under the liquor tax law. In addition, the sparkling beverage 1 may be a sparkling beverage which is not a beer-taste beverage. Below, the example in which the foamable drink 1 is a beer is demonstrated.

  The foam 3 of the foamable beverage 1 is a so-called fine foam, which is different from the coarse foam produced 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 texture of the foamable beverage 1 and also functions as a lid to prevent the smell of the liquid 2 or the escape of carbon dioxide gas and the oxidation of the liquid 2. Preferably it is produced. Fine bubbles are also generated from frosty mist 4 which appears at the boundary between liquid 2 and bubbles 3.

  Frosty mist 4 is a misty layer appearing at the boundary between liquid 2 and bubble 3. The frosty mist 4 is generated by applying a gas pressure when the sparkling beverage 1 is poured into the beverage container C. Since the frosty mist 4 regenerates the foam 3 when the foamable beverage 1 is ingested, the effect of improving the foam stability of the fine foam is obtained. Specifically, when the foamable beverage 1 is consumed, the frosty mist 4 is brought into contact with the liquid 2, the foam 3 or the beverage container C to be stimulated, whereby the fresh foam 3 is regenerated from the frosty mist 4. When frosty mist 4 appears clearly and frosty mist 4 increases, the regeneration amount of foam 3 increases. In the foam measuring device and the foam measuring method of the present embodiment, it is possible to measure the amount of regenerated foam 3.

  As shown in FIG. 2 and FIG. 3, the foam measuring device 10 according to the present embodiment includes, for example, a hole drilling machine 20 for drilling a hole in a closed container M filled with the foamable beverage 1; The server 30 which pours out, the inclination apparatus 40 which inclines the drink container C in which the foamable drink 1 was contained, and the foam | form measurement part 50 which measures the foam | bubble 3 of the foamable drink 1. FIG. The closed container M indicates a container in which the foamable beverage 1 is packaged, and may be a can filled with the foamable beverage 1 or a bottle filled with the foamable beverage 1 . Moreover, containerization has shown the state which filled and sealed the foamable drink in containers, such as a can or a bottle.

  As shown in FIG. 2, the punching machine 20 includes, for example, a base 21, a support 22 extending upward from the base 21, a base 23 located on the base 21, and a pressing portion 24 for pressing the sealed container M. A holding unit 25 provided above the pressing unit 24, a rod-like unit 26 passing through the holding unit 25 and the pressing unit 24, and a carbon dioxide gas cylinder 27 are provided. The base 21 has, for example, a rectangular parallelepiped shape, and includes 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 sealed container M is pressed below the pressing portion 24.

  A pressing portion 24 and a gripping portion 25 are supported by the column 22, and the pressing portion 24 can be changed in position 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 table 23 is movable up and down relative to the base 21 and moves up and down according to the rotation operation of the lever 21 b. For example, the airtight container M which is a can is placed on the stand 23 in a state of being turned upside down.

  The rod-like portion 26 is provided with a grip portion 26a at its upper end, and can be moved up and down by holding the grip portion 26a. The rod-like portion 26 is a site for making a hole in the closed container M placed between the pedestal 23 and the pressing portion 24 and the hole is made in the closed container M by moving downward. From the holding part 26a, the flow path F1 through which the foamable beverage 1 of the closed container M flows is extended.

  The carbon dioxide gas cylinder 27 supplies carbon dioxide gas to the foamable beverage 1 to pressure-feed the foamable beverage 1 from the rod 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 pressing portion 24 and the rod portion 26, and the flow path F1 connects the punching machine 20 and the server 30 to each other. Therefore, the foamable beverage 1 inside the sealed container M is pressure-fed by the carbon dioxide gas from the carbon dioxide gas cylinder 27 from the sealed container M having a hole through the rod portion 26 and the flow path F1 to the server 30.

  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 foamable beverage 1 flows, 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 pours the foam 3 according to the lever 33a which is operated to swing by hand, the liquid dispensing portion 33b which dispenses the liquid 2 according to the swing operation of the lever 33a, and the swing operation of the lever 33a. And a bubble pouring portion 33c. For example, in a state where the beverage container C is disposed below the liquid pouring portion 33b and the bubble pouring portion 33c, pulling the lever 33a (swing the lever 33a to the right in FIG. 2) The liquid 2 is poured into the container C. Further, 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 pouring portion 33c into the beverage container C.

  As shown in FIG. 3, the beverage container C into which the liquid 2 and the foam 3 have been dispensed is placed on the tilting device 40. The tilting device 40 rotates by supporting the beverage container C, the base 41, the support portion 42 extending in a pair from the base 41, the rotation portion 43 rotatable relative to each support portion 42, and the beverage container C. And a container rotation unit 44 that rotates together with the unit 43. The support portion 42 includes a pair of columns 42a extending upward from the base 41, and a support 42b supported by the columns 42a, and the pivoting portion 43 is inserted in each support 42b in the horizontal direction.

  The pivoting portion 43 extends in the horizontal direction between the pair of supports 42b, and includes a motor 43a and a control unit 43b outside the pair of supports 42b. The motor 43a generates a rotational driving force for rotating the container rotation unit 44 with the rotation unit 43 as a central axis, and the control unit 43b controls the motor 43a. As shown in FIG. 3 and FIG. 4 (b), the beverage container C rotates with the container rotation portion 44 with the rotation portion 43 as a central axis. 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 to turn to the angle θ, and the time to maintain the angle θ can be set. The control unit 43b controls the motor 43a so that the beverage container C inclines at the set angle θ and time.

  The container rotation unit 44 includes a base 44a on which the beverage container C is placed, a connection part 44b connecting the base 44a and the rotation part 43 to one another, and a lid extending upward from the connection part 44b and covering the upper end of the beverage container C And 44c. In FIG. 4A to FIG. 4C, illustration of part of the container rotation unit 44 is omitted. 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 pedestal 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 44c is provided 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 perforations 44g, and the pair of perforations 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 44 g is formed by a chord 44 h of a circular lid 44 c and an arc 44 j.

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

  By covering the lid 44c on the beverage container C, it is possible to prevent a large amount of foam 3 from flowing out from the beverage container C. Also, normally, when drinking the sparkling beverage 1, the sparkling beverage 1 is consumed by suppressing the foam 3 with the upper lip, but the upper lip of the drinker can be reproduced on the portion of the chord 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 ingested in the mouth of the drinker. The pair of holed portions 44g are directed in the depth direction and the front direction in the plane of FIG. By providing the lid 44c, it is possible to more accurately reproduce the state in which the sparkling beverage 1 is ingested in the mouth of the drinker. Therefore, it is more preferable to attach the lid 44c and measure the foam 3.

  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 attached to the wall 44 d, and by looking at the bubble measuring unit 50, it is possible to grasp the thickness of the bubble 3 at a glance. 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 other than the ruler attached to the wall 44 d. That is, the bubble measuring unit 50 may be a ruler that is manually applied to the beverage container C, or an image processing apparatus 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 foam measurement method according to the present embodiment will be described with reference to FIG. Drawing 6 is a flow chart which shows an example of each process of a bubble measuring method concerning this embodiment. First, the closed container M filled with the foamable beverage 1 is installed in the punching machine 20 (step S1). Specifically, as shown in FIG. 2, the closed container M placed upside down is placed on the base 23, and the lever 21b is pulled to turn the lever 21b, thereby pressing the closed container M from above and below. The upper and lower positions of the closed container M are fixed.

  A hole is made in the closed container M with the upper and lower positions of the closed container M fixed (step S2). At this time, by holding the grip portion 26 a by hand and lowering the rod portion 26, the rod portion 26 is pierced into the closed container M to make a hole in the closed container M. The foamable beverage 1 inside the sealed container M is pressure-fed to the server 30 through the rod portion 26 and the flow path F1 (step of pumping the foamable beverage).

  Next, the foamable beverage 1 is poured out from the server 30 into the beverage container C (step S3, a step of pouring out the foam). Specifically, by holding the beverage container C with one hand and arranging the beverage container C under the liquid outlet 33b and pulling the lever 33a in a state where the beverage container C is inclined, the liquid in the beverage container C is obtained. Pour 2 a fixed amount (for example, 60% or more and 80% or less of the capacity of the beverage container C). Then, the inclination of the beverage container C is brought close to vertical and the lever 33a is pushed, whereby a predetermined 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 ratio of the volumes of the liquid 2 and the bubbles 3 is, for example, about 7: 3.

  Subsequently, as shown in FIG. 3 and FIG. 4 (a), the beverage container C is installed in the inclination device 40 (step S4). At this time, the beverage container C is placed on the platform 44 a along the horizontal surface H, and the lid 44 c is placed on the beverage container C. Then, after the first time has elapsed since pouring out the foam 3, as shown in FIG. 4B, the beverage container C is inclined (step S5, the step of inclining the beverage container). The first time is a time on the assumption that the effervescent beverage 1 is poured into the beverage container C until the effervescent beverage 1 is consumed, 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 the pouring of the sparkling beverage 1 to the drinking. Furthermore, as an example, the first time may be 60 seconds. The angle θ of the bottom 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 that assumes the angle at which the beverage container C can be tilted when the sparkling beverage 1 is consumed. As an example, the angle θ may be 65 °.

  When the beverage container C is inclined, the sparkling beverage 1 is poured out of the beverage container C, and the poured sparkling beverage 1 is accommodated in a container such as a bucket. After the second time has elapsed since the beverage container C was tilted, as shown in FIG. 4C, the tilted beverage container C is returned to the original state (step S6, the step of returning the beverage container). The second time is a time that assumes the time until the beverage container C is tilted and then returned, 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, as shown in FIG. 7A, the frosty mist 4 extends downward from the foam 3, and the area of the frosty mist 4 and the foam 3 gradually rises. Thereafter, as shown in FIG. 7B, the frosty mist 4 is regenerated as the foam 3 and the foam 3 is thickened, and the area of the foam 3 and frosty mist 4 is increased and the area of the frosty mist 4 is decreased. Then, as shown in FIG. 7C, the regeneration of the bubbles 3 further proceeds, and the thicknesses of the bubbles 3 and the liquid 2 become constant when the bubbles 3 are further thickened.

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

  Next, the foam measuring method and the effects obtained from the foam measuring apparatus 10 according to the present embodiment will be described in detail. In the foam measurement method according to the present embodiment, as shown in FIGS. 4A to 4C, the first time after the liquid 2 and foam 3 of the foamable beverage 1 are poured out to the beverage container C After it has elapsed, the beverage container C is tilted. Thus, by setting the time from the pouring of the sparkling beverage 1 to the drinking time as the first time, the condition from the pouring of the sparkling beverage 1 to the drinking is actually simulated. Can.

  In addition, after the beverage container C is inclined, after the second time has elapsed, the inclination of the beverage container C is returned to the original, and the amount of foam 3 generated when it is returned is measured. Therefore, the amount of regeneration of foam 3 can be measured after simulating the condition from drinking to return of the beverage container C by setting the time for tilting the beverage container C and taking it for the second time. it can. Therefore, by simulating actual drinking of the sparkling beverage 1 and measuring the amount of foam 3, the amount of regenerated foam 3 can be stably and accurately measured. As a result, the regeneration conditions of the foam 3 after drinking can be appropriately explored. Here, the “amount of foam” includes the regenerated amount of foam 3 and the amount of foam 3 generated from the beginning of the beverage container C.

  Further, the first time described above 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 sparkling beverage 1 is poured until when it is consumed. Therefore, the amount of fine bubbles 3 regenerated can be measured more accurately. Specifically, the beverage container C can be inclined in a state in which the frosty mist 4 is reliably generated by setting the first time from the pouring to the tilting to be 10 seconds or more. Moreover, before the beverage container C is inclined, the possibility that the frosty mist 4 disappears can be suppressed by setting the first time to 300 seconds or less.

  Further, in the step of inclining the beverage container C, the beverage container C may be inclined such 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 at the time of drinking can be more accurately simulated. Therefore, the amount of regeneration of the fine bubbles 3 can be measured more accurately.

  In addition, the sparkling beverage 1 may be packaged in the closed container M before being poured out from the server 30. Then, in the step of pouring out, the foamable beverage 1 is container-packed before the step of pouring out the liquid 2 and the foam 3 of the foamable beverage 1 from the server 30 which pours out the sparkling drink 1. A step may be provided in which a hole is opened in the closed container M and the foamable beverage 1 is pumped from the closed container M to the server 30. In this case, in order to pump the foamable beverage 1 to the server 30 by drilling holes in the closed container M in which the foamable beverage 1 is packaged, measure the amount of regenerated foam 3 of the foamable beverage 1 packaged. Can. That is, since the amount of regenerated foam 3 can be measured also for the container-packed sparkling beverage 1, a versatile foam measuring method can be obtained.

  In particular, when the 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 can not be generated. However, in the present embodiment, the closed container M is installed in the perforation machine 20, and the foamable beverage 1 of the closed container M is poured out from the server 30 connected to the perforation 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 amount of regenerated foam 3 can be measured.

  The foam measuring device 10 according to the present embodiment can simulate the drinking state of the foamable beverage 1 by tilting the beverage container C, from which the foamable beverage 1 is poured out from the server 30, with the tilt device 40. . In addition, by returning the beverage container C tilted by the tilting device 40, it is possible to simulate a state from drinking until the beverage container C is returned to the original. The amount of regenerated foam 3 can be measured by measuring the foam 3 by the foam measuring unit 50 when the beverage container C is returned. Therefore, the simulated amount of foam 3 can be measured after simulating the actual drinking of the sparkling beverage 1, so that the regenerated amount of foam 3 can be stably and accurately measured.

  Furthermore, in the foam measuring method and the foam measuring apparatus 10 according to the present embodiment, not only the regenerated amount of foam 3 but also other characteristics of foam 3 can be measured in a timely manner with respect to beverage container C after tilting and returning. can do. In addition, the amount of foam 3 immediately after being poured into the beverage container C can also be measured. Note that, 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 inclined a plurality of times.

  Moreover, the foam measuring apparatus 10 may be equipped with the lid 44c in which the perforated part 44g which is mounted | worn with the drink container C and from which the liquid 2 and the foam | form 3 are discharged | emitted is formed. In this case, by providing the lid 44c attached to the beverage container C, it is possible to discharge the liquid 2 and the foam 3 from the perforated portion 44g of the lid 44c. The perforated portion 44g of the lid 44c can reproduce the state in which the effervescent beverage 1 is taken in the mouth of the drinker. Therefore, since the beverage container C can be inclined 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 is provided with a punching machine 20 connected to the server 30 and drilling holes in the sealed container M, and the foamable beverage 1 inside the sealed container M is pressure-fed from the drilling machine 20 to the server 30 May be dispensed into the beverage container C. In this case, since the hole making machine 20 opens the hole in the closed container M and pumps the foamable beverage 1 to the server 30, it is possible to measure the amount of regenerated foam 3 of the containerized foamable beverage 1. That is, since the regeneration amount of the foam 3 can be measured with respect to the container-packed sparkling beverage 1, 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 device concerning the present invention was described, the present invention is not limited to the above-mentioned embodiment, and it changes in the range which does not change the gist described in each claim. Or may be applied to other things.
