Description

  The present invention relates to a technique for measuring a gas pressure of a gas-containing beverage, particularly a gas-containing beverage such as beer, in a state where it is actually drunk in a drinking container such as a glass or a mug.

  The gas pressure of beer, which is a carbonated beverage, is known to have an important effect on beer flavor and foam formation, and this gas pressure is an important factor for taste when designing products. (For example, refer nonpatent literatures 1 and 2.).

  In addition, this gas pressure is strictly controlled in the manufacturing process, and in the production line, after being measured by in-line sensors in the piping and filled in beverage supply containers such as bottles, cans and barrels, Process control is carried out by measuring with a dedicated measuring instrument.

  In addition, when drinking, it is well known that the taste changes depending on how the above beverage supply container is poured into a drinking container such as a glass or a mug, and “delicious pouring of beer” is well discussed. .

  In addition, the skill of how to pour beer affects the way bubbles are formed, but at the same time, it leads to a difference in the escape of gas in the liquid, which causes a difference in the gas pressure of the poured beer. This difference is considered to affect the sensuality when drinking (feeling of irritation in the mouth, throat over swallowing, etc.) (for example, see Non-Patent Document 3).

  Also, it is known that carbonated beverages other than beer have a carbon dioxide gas concentration that matches their unique flavor (see, for example, Non-Patent Document 4).

  As described above, in beer etc., it is well known that the way of pouring affects the gas pressure and the taste changes, but it is in an open state after being poured into a drinking container and actually being drunk There are no reports of the gas pressure of beer in Japan.

  Further, as related, in Patent Document 1, in the manufacturing process, a predetermined amount of carbonated beverage is stored in a measurement container before filling a casing such as a bottle or can, and the principle of the syringe is stored in the measurement container. A technique for measuring the content of carbon dioxide gas by inserting a needle of a measuring instrument to which is applied and sucking a beverage in a measuring container is disclosed (for example, see Patent Document 1).

  Patent Document 2 discloses a technique for measuring a qualitative parameter (not a quantitative parameter) unique to a product such as alcohol, sugar, carbon dioxide gas of beer contained in a casing such as a bottle or a can ( For example, see Patent Document 2.)

Moreover, what is disclosed by these patent documents 1 and 2 is not about the measurement of the gas pressure of beer in the state which actually drinks. On the other hand, although there is a report about the measurement of the sample after dispensing (see, for example, Non-Patent Document 5), it is necessary to transfer the sample to the analyzer after pouring into a special container. Since the gas pressure changes due to the passage of time or changing work, it is difficult to measure the gas pressure of the gas-containing beverage in the same situation as the consumer actually drinks.

Next, embodiments of the invention will be described.
The present invention uses carbon dioxide-containing alcoholic beverages such as beer, happoshu, miscellaneous sake, and champagne, carbon dioxide-containing non-alcoholic beverages (soft drinks) such as cider, and carbonated water as well as a single beverage. It is applicable to the measurement of gas pressure for mixed drinks such as cocktails such as fizz. The gas to be measured includes not only carbon dioxide gas but also nitrogen and other gases that can be used for beverages.

  Moreover, these drinks are accommodated in the drink supply container used when providing from a manufacturer to consumers, such as a bottle, a can, and a barrel.

  In addition, beverages are poured from these drinking supply containers into the drinking containers used when consumers actually drink. This drinking container includes a cup, a glass, a mug, a coblet and the like. In addition to these, for example, a pitcher that is once poured out from a barrel and then delivered to a consumer where the consumer again pours it into their own drinking container is also included.

  And, as described above, the gas pressure of the beverage in a state where it is poured into a drinking container and consumed by a consumer is measured. In the following examples, the beer poured into a glass is measured. An example of measuring the gas pressure will be described.

  As shown in FIG. 1, Example 1 uses beer glass 1 as a drinking container, pours beer 2 into the beer glass 1, and supplies the beer 2 to the pressure measuring unit 30, thereby containing the beer 2 in the beer 2. This is an example of measuring the gas pressure.

  And as shown in FIG. 1, in the gas pressure measuring apparatus 100 of the present Example 1, the housing | casing part 10 which forms the storage space 11 of the beer glass 1 into which the beer 2 used as the measurement object of gas pressure was poured, A needle 21 as a sampling unit inserted into the beer glass 1, a pressure supply unit 22 for setting the inside of the accommodation space 11 to a specified pressure, and a beer 2 as a measurement object sampled from the needle 21 And a pressure measuring unit 30 for measuring the gas pressure of the beer 2. The casing 10 is installed on the measurement table 40. The housing 10, the needle 21, and the pressure supply unit 22 are installed in the safety shield 50.

  In the following, each part will be described. As shown in FIG. 2, the casing 10 is configured by assembling an upper accommodation part 12 and a lower accommodation part 13 that constitute an accommodation space 11 in which the beer glass 1 is accommodated. The upper housing portion 12 and the lower housing portion 13 have bottomed tubular portions 12a and 13a, respectively, and a series of tubular housing spaces 11 is formed by communicating the tubular portions 12a and 13a. It is supposed to be composed. A female screw part 12 b is provided at the lower part of the upper housing part 12, and a male screw part 13 b is provided at the upper part of the lower housing part 13, and the upper housing part 12 is fastened and fixed to the lower housing part 13. It can be done. Moreover, the cylindrical part 13a of the lower side accommodating part 13 can be open | released by removing from the lower side accommodating part 13 by rotating the upper side accommodating part 12 and loosening tightening. Note that, as in the present embodiment, the housing unit 10 is configured to be integrated by a screwing type, for example, in a so-called fitting type in which the upper housing unit 12 and the lower housing unit 13 are fitted. It is good also as a structure which suppresses the shake of the beer glass 1 to the minimum at the time of integration.

  As shown in FIG. 2, an annular groove 13 d is provided on the upper surface 13 c of the lower housing part 13, and an O-ring 14 is embedded in the annular groove 13 d, and the O-ring 14 is disposed on the lower surface of the upper housing part 12. 12c and the upper surface 13c of the lower housing part 13 are sandwiched. Thereby, the airtightness of the accommodating space 11 formed between the upper accommodating part 12 and the lower accommodating part 13 can be ensured. The O-ring 14 can be made of a general elastic material such as rubber or resin.

  Further, as shown in FIG. 2, a positioning portion 13f is projected downward from the lower housing portion 13, and the positioning portion 13f is inserted into the fitting hole 40f of the measuring table 40. Thus, the casing unit 10 can be aligned with the measurement table 40.

  As shown in FIG. 2, a through hole 12 e penetrating in the vertical direction is provided in the upper center of the upper housing portion 12, and the upper opening of the through hole 12 e is a sealing lid provided at the lower portion of the adapter 20. Closed by part 23. Further, a needle 21 protruding downward from the sealing lid portion 23 is inserted into the through hole 12e.

  In addition, as shown in FIG. 2, the sealing lid portion 23 is provided with a pressure supply portion 22 configured by a communication passage communicating with the through hole 12e. The pressure supply unit 22 is supplied with a high-pressure pressure gas (for example, 4 Mpa of pressure air (pressure air)) from a gas pressure supply device (not shown) via a pressure gas pressure supply pipe 24. However, it is supplied into the accommodation space 11 through the through hole 12e. The pressure gas is preferably air (air in the atmosphere) from the viewpoints of cost and simplicity, but air, nitrogen gas, neon gas, argon gas, and helium gas are other than the gas contained in the measurement object. Various gases can be used. For example, in the case of a general carbon dioxide-containing beverage, it is desirable to use a gas other than nitrogen gas when the object to be measured contains nitrogen gas, such as air and nitrogen gas, and some overseas beers.

  In addition, as shown in FIG. 2, the sealing lid portion 23 is constituted by an elastic member made of rubber, resin or the like, and the through hole 12e is closed by abutting the lower end surface 23a of the through hole 12e. It is configured.

  Further, as shown in FIG. 2, a pressure gas having a pressure P is supplied to the accommodation space 11 from the pressure supply unit 22, and the inside of the accommodation space 11 is maintained at the pressure P. Due to this pressure P, the upper surface of the beer 2 is pressed downward, and the beer 2 flows in from the tip of the needle 21 and rises in the needle 21. The needle 21 is a tubular member made of stainless steel or the like, is configured to allow the beer 2 to circulate therein, and functions as a sampling unit for collecting the beer 2.

  Here, as shown in FIG. 3, in the housing space 11, a gap 11 a is provided between the beer glass 1 and the pressure gas supplied from the pressure supply unit 22 flows. . Thereby, in the beer glass 1, since the uniform pressure P is applied to the inner surface 1a and the outer surface 1b of the beer glass 1, the problem that the beer glass 1 is broken by the pressure P can be prevented.

  Further, as shown in FIG. 3, the casing 10 receives the pressure P on the inner wall surface of the housing space 11 inside thereof, and therefore needs to be formed in a pressure resistant container that can withstand the pressure P. In the present embodiment, the upper housing portion 12 and the lower housing portion 13 can each be secured with sufficient thickness so as to withstand the pressure P, thereby preventing the housing portion 10 from being damaged. It is like that. The material of the housing unit 10 is not particularly limited as long as the pressure resistance can be ensured. For example, the material may be made of a transparent material such as acrylic (may be translucent). According to the method, it is possible to visually recognize the operation of the needle 21 and the behavior of the beer 2 from the outside.

  Further, as shown in FIG. 1, the casing 10 is installed on the measuring table 40 in a state where the beer glass 1 is accommodated therein, and is enclosed in a safety shield 50, thereby being enclosed in a closed space. Will be placed. Here, the safety shield 50 is provided in consideration of prevention of debris and beverage scattering to the surroundings in the event of a failure in which the casing 10 is damaged by the pressure P in the accommodation space 11. It is. In addition, although it does not specifically limit about the raw material of the safety shield 50, For example, according to comprising by transparent materials (it may be translucent), such as an acryl, the said needle | hook 21 is externally provided. The operation and the behavior of the beer 2 can be visually confirmed, which is preferable.

  Further, as shown in FIG. 2, the needle 21, the pressure supply unit 22, and the sealing lid unit 23 described above are integrally configured as an adapter 20, and the adapter 20 is configured to move up and down as shown in FIG. Is configured to move up and down via the belt 26. The raising / lowering drive unit 25 has a motor-driven gear, and the belt 26 is sent upward or downward by forward / reverse rotation of the motor by engaging the gear with the belt 26. Yes. A vertical through hole 50a is provided in the upper part of the safety shield 50 so that the adapter 20 can be moved up and down by the belt 26. Rods 20a and 20a for supporting the adapter 20 at the lower part and a pressure gas pressure supply pipe 24 (see FIG. 2) are also passed through the through hole 50a. In addition, the specific configuration of the lifting drive device 25 is not particularly limited, and can be realized by other known configurations.

  In addition, as shown in FIG. 1, the pressure measuring unit 30 that measures the gas pressure of the beer 2 sampled by the needle 21 distributes or stores the liquid to be measured in the liquid, so that the The pressure of the gas contained in is measured, and a commercially available one can be used, and the specific configuration is not particularly limited. Further, the pressure measuring unit 30 may have a configuration capable of measuring not only carbon dioxide gas but also pressures of other gas components. Here, it is important to supply the beer 2 sampled by the needle 21 to the pressure measuring unit 30 without being exposed to the outside air. Thereby, the gas pressure contained in the beer 2 poured into the beer glass 1 can be measured almost directly without causing a decrease due to the opening to the atmosphere.

  In the above configuration, at the time of measuring the gas pressure, as shown in FIG. 1, the housing unit 10 that houses the beer glass 1 is set in the safety shield 50. As shown in FIG. 2, the adapter 20 is lowered, and the through hole 12 e of the sealing lid portion 23 is closed by the sealing lid portion 23. Further, the needle 21 is lowered and inserted into the beer 2 in the beer glass 1. Further, the pressure supply part 22 supplies a high pressure gas P into the accommodation space 11 through the through hole 12e, and the inside of the accommodation space 11 is maintained in a high pressure state. The liquid level of the beer 2 is pushed downward under high pressure, whereby the beer 2 flows into the tip 21a of the needle 21 and is sampled.

  As shown in FIG. 1, the sampled beer 2 is supplied to the pressure measuring unit 30 via the needle 21 and the sampling pipe 27 connected to the needle 21, and the gas is measured by the pressure measuring unit 30. The pressure is measured, and the measurement result is displayed on the display unit 31.

  On the other hand, when the gas pressure is not measured, the adapter 20 and the needle 21 shown in FIG. 1 are raised and the pressure supply from the pressure supply unit 22 is stopped. And the housing | casing part 10 is taken out by opening the safety shield 50. FIG.

  Further, as shown in FIG. 1, in the above series of operations, the operations of the adapter 20, the needle 21, and the pressure supply unit 22 and the operation of starting / ending the pressure measurement by the pressure measuring unit 30 are performed in conjunction with each other. It is desirable to be configured. For example, the interlocking operation can be performed by an operation using the operation button 32 provided in the pressure measurement unit 30. The configuration for the interlocking operation can be realized by a well-known technique using a microcomputer, and the description thereof is omitted. In addition, a safety mechanism may be provided so that the adapter 20, the needle 21 and the like are not operated when the safety shield 50 is opened.

Next, measurement examples and measurement results of gas pressure performed using the gas pressure measuring apparatus 100 having the above configuration will be described.
In this measurement example, beer is used as a beverage whose gas pressure is to be measured, and the relationship between the pouring method and the gas pressure is verified. From the relationship, the reliability of the gas pressure measuring device 100 according to the present embodiment is ascertained. Evaluation was performed.

In this example, as shown in FIG. 4, two types of pouring methods A and B were performed.
<How to pour A>
Step A1: With the beer glass 1 tilted obliquely, the beer glass 1 is brought close to the spout 61 of the beer server and the beer 2 is made to follow the inner wall surface of the glass without foaming. Pour gently into.
Step A2: When the beer 2 is about the seventh minute of the glass, the beer glass 1 is made almost upright, and finally the handle of the beer server is tilted in the opposite direction to adjust the foam 3 to be applied.
<How to pour B>
Step B1: The beer glass 1 is made substantially upright, and the beer 2 is poured directly onto the bottom of the beer glass 1 so that the foam 3 is formed immediately after the start of pouring.
Step B2: When the foam 3 rises to a height of about 1/3 of the glass, the beer glass 1 is tilted at an angle, and the inner wall surface of the beer glass 1 is brought close to the spout 61 of the beer server to add additional foam. Gently pour beer 2 along the inner wall of the glass so that 3 does not stand.
Step B3: When the foam 3 reaches the top of the glass, the beer glass 1 is made almost upright, and the pouring is finished immediately before the foam overflows from the glass.

<Measurement conditions>
Internal pressure (pressure of the pressure gas P) in the housing space 11 of the casing 10: 4 MPa
Gas pressure measuring device: CarboQC (manufactured by Anton Paar)
Beer: Commercial beer barrel product (made by a domestic beer company)
Beer glass: 360 ml (uses a commercially available special detergent, special sponge, washed, left to cool in an oven set at 8 ° C for more than 30 minutes after natural drying)
Beer temperature: about 8 ℃
Number of measurements: 10 times pouring A, 10 times pouring B

<Measurement procedure>
The beer 2 is poured into the beer glass 1 by the above-described pouring method A or B, and the beer glass 1 is set in the lower housing portion 13 of the housing portion 10 as shown in FIG. And the upper accommodating part 12 is attached to the lower accommodating part 13, and the beer glass 1 is accommodated in the housing | casing part 10. FIG. And the housing | casing part 10 is installed on the measurement stand 40, the safety shield 50 is closed, the operation button 32 of the pressure measurement part 30 is operated, and a measurement is started. After the measurement, the safety shield 50 is opened and the casing unit 10 is taken out, the upper housing part 12 of the casing unit 10 is removed, and the beer glass 1 is taken out. In the next measurement, a new beer glass 1 is prepared, the beer 2 is poured by the pouring method A or B, and the measurement is performed in the same manner.

<Measurement results>
When measured as described above, a normal distribution was obtained in each of the pouring methods A and B as shown in FIG. Thereby, it was confirmed that there is a significant difference in the gas pressure of the beer 2 after being poured into the beer glass 1 depending on how the beer 2 is poured.

  As described above, the gas pressure of the beer 2 poured into the beer glass 1 can be measured. And, conventionally, the gas pressure of the poured beer was supposed to have an effect on the sensation when drinking (irritation in the mouth, throat over when swallowing, etc.). It becomes possible to measure the gas pressure of the poured beer quantitatively, and it becomes possible to evaluate how to pour the beer 2 by combining this quantitative measurement result with the sensuality.

  In addition, traditionally, it has been thought that the way in which beer is poured leads to a difference in the way gas escapes from the liquid, which in turn causes a difference in the gas pressure of the poured beer, and this recognition is common. However, even in the above measurement, it was confirmed that the difference occurs. Judging from this recognition, it can be said that the measurement method of this embodiment is highly reliable. In the above example, the case where the beer packed in the barrel was poured into the glass from the beer server was verified, but the same measurement was performed when the beer was poured into the glass etc. by hand using canned beer or bottled beer.・ It can be evaluated.

The present embodiment is configured as described above.
That is, as shown in FIG. 1 and FIG. 2, a case portion 10 that forms a storage space 11 for a beer glass 1 into which beer 2 to be measured for gas pressure is poured, and the beer glass 1 are inserted into the beer glass 1. A needle 21 as a sampling unit, a pressure supply unit 22 for setting the inside of the accommodation space 11 to a specified pressure, and a beer 2 as a measurement target sampled from the needle 21 are taken in, and the gas pressure of the beer 2 is And a pressure measuring unit 30 for measuring a gas-containing beverage gas pressure measuring device 100.

  According to such a gas pressure measuring device 100, it is possible to measure the gas pressure of the beer 2 that is actually drunk while being poured into the beer glass 1. By using this measurement result, the difference in gas pressure depending on the pouring method can be numerically grasped and evaluated, and the pouring method can be selected and verified according to different product qualities. Moreover, even if the same pouring method is used, the difference between skilled and unskilled persons can be grasped and evaluated numerically, which can be used for evaluating and verifying the skill level of the person in charge of pouring at restaurants and the like.

  Furthermore, for example, when performing sensory evaluation such as over the throat, it is possible to perform evaluation under the control of gas pressure (in a state where the gas pressure is grasped). Moreover, since it is thought that gas pressure changes also with the shape, capacity | capacitance, and temperature of the drinking container of the beer glass 1, the characteristic and gas pressure relevant to a drinking container can also be evaluated. In addition, it can be widely used for sales promotion and training such as measuring and evaluating gas pressure on the spot in stores, tasting venues, events and workshops.

  Moreover, as shown in FIG.2 and FIG.3, the said housing | casing part 10 is comprised by the pressure | voltage resistant container comprised so that accommodation / removal of the said beer glass 1 was comprised, and in the said accommodation space 11, it is with the said beer glass 1. In the meantime, a gap 11a into which the pressure gas supplied from the pressure supply unit 22 flows is secured.

  With this configuration, as shown in FIG. 3, since the uniform pressure P is applied to the inner side surface 1 a and the outer side surface 1 b of the beer glass 1, the problem that the beer glass 1 is broken by the pressure P can be prevented.

  As shown in FIG. 2, the casing 10 is provided with a through hole 12 e, and the gas pressure measuring device 100 includes a sealing lid 23 that closes the through hole 12 e, and the sealing lid 23. An adapter 20 is provided, which includes the needle 21 that is provided so as to be relatively movable, and the pressure supply portion 22 that is provided in the sealing lid portion 23 and that supplies a pressure gas to the through hole 12e. With the sealing lid portion 23 of the adapter 20 attached to the through hole 12e of the sealing lid portion 23, the needle 21 is inserted into the beer glass 1 and the pressure gas from the pressure supply portion 22 is It is set as the structure by which supply in the accommodation space 11 is performed.

  With this configuration, the housing portion 10 is provided with a through hole 12e only at one location, the needle 21 is inserted from the adapter 20, the pressure gas is supplied from the pressure supply portion 22, and the through hole is formed by the sealing lid portion 23. By performing the closure of 12e, sampling can be performed, and the structure of the housing 10 can be simplified and excellent airtightness can be ensured.

  In addition, the gas pressure measuring device 100 includes a safety shield 50 that surrounds the casing 10.

  Thereby, when the malfunction which the housing | casing part 10 was damaged with the pressure P in the said storage space 11 can prevent the scattering of the fragment to the circumference | surroundings etc. can be aimed at.

  The casing 10 and / or the safety shield 50 are made of a transparent or translucent material.

  Thereby, it becomes possible to visually recognize the operation of the needle 21 and the behavior of the beer 2 from the outside.

  Further, as shown in FIG. 2, a housing space 11 for the beer glass 1 into which the beer 2 to be measured for gas pressure is poured is formed as the structure of the housing unit 10 and is inserted into the beer glass 1.
