Description

  The present invention relates to a method of distributing a beverage in a container in a layered manner when the beverage is distributed and served in a container such as a drinking container at the time of drinking or in a restaurant, etc., and the layer structure of the beverage in the container The present invention relates to a jig for performing distribution.

  Various beverages are provided at restaurants and the like. In providing beverages, in order to increase the palatability, the palatability is also increased by appealing to the visual form of the shape, such as a cocktail, a float type, and a topping type. Conventionally, a cocktail has been known as a method of providing a beverage characterized by visual beauty in a drinking container. As one of the providing methods, a cocktail distributed in a multilayer shape is known. In the cocktail field, such multi-layered cocktails are collectively referred to as “Poos Cafe Style” and are more widely known. Cocktails are provided in this way in a multi-layered shape, characterized by visual beauty and accepted by consumers, but beverages distributed in such a multi-layered shape are A plurality of types of beverages having different colors and specific gravity are stacked in a layer for each beverage using the specific gravity difference.

  Conventionally, the following method has been used to produce a multilayer cocktail. First, among beverages to be used, a beverage having the highest specific gravity is normally poured into a glass to form a first layer (lowermost layer). Next, the next heavy drink is gently poured into the glass so as not to be mixed with the first drink to form the second drink. The same pouring process as the second layer is repeated until all the prepared types of beverage are used. Here, in order to gently pour the second and subsequent layers of beverage into the glass, the tip of a drink stirring bar called Madler or an elongated spoon called Bar Spoon (Patent Document 1) is brought into contact with the inner wall surface of the glass. A small amount was poured into the inner wall of the glass through a mudler or bar spoon. However, this method using a mudler or a bar spoon requires a considerable degree of technical skill and has problems in terms of simplicity, etc., and any other method used for dispensing the multi-layer cocktail can be used. It could not be applied to beverages.

  In recent years, in the field of beverages different from the field such as cocktails, a method has been proposed in which beverages are distributed and provided in a drinking container in a multilayer shape. For example, Patent Document 2 discloses a method of dispensing a beverage having two or more liquid layers into a container using a concentrated liquid such as coffee or milk. The method includes providing at least one source of a first concentrate and at least one source of a second concentrate, diluted from the first concentrate source and into a drinking container. A second liquid diluted to a concentration lower than the concentration of the liquid layer is supplied above the supplied beverage to form a layered liquid layer. In this method, by controlling the dilution rate of the concentrated liquid with water, the dilution rate in the upper liquid is made higher than that in the lower liquid, and the liquid is gently supplied into the container. However, this method is limited to the provision of a specific beverage, such as when using a concentrated liquid, and the first liquid layer and the second liquid layer are distributed. In order to prevent the turbulent flow of the liquid layer of the liquid, the flow rate of the second liquid is adjusted and the liquid is gently fed, but when applied to beverages other than the above, It is difficult to provide a beverage in a beverage container that is distributed in layers, and therefore the method of this disclosure is only applicable to limited beverages.

  Recently, a jig for producing a two-layer beer more easily has been devised in beer and the like whose specific gravity approximates and is provided to consumers together with the beer. Such a conventional jig (hereinafter referred to as “conventional jig”) has a support for placing the jig in the opening of the container, and a partial spherical shape (a very shallow bowl for pouring beverage from above). It consists of a part that looks like a face down. After setting the conventional jig in the opening of the glass into which the first layer of beer is poured, when the second layer of beer is poured from the vicinity of the top of the partial spherical shape, the beer diffuses around the partial spherical shape, The aim of conventional jigs is to suppress the mixing of the second layer beer and the first layer beer and form a layer structure. However, in order to successfully produce a two-layer beer with a conventional jig, it is necessary to continue to pour the second layer of beer evenly, stably and quietly near the top of the conventional jig, and dispense a clear layered beer. However, considerable skill was still required. In other words, even if the beer in a container is tilted at the same position and at the same angle, the position where the beer flows down varies depending on the remaining amount of beer. Not only does it not sufficiently diffuse onto the surface of the jig's partial spherical shape, making it impossible to make a two-layer beer, but the thin layer of liquid that flows down the top of the spherical shape of the jig will also be Due to the nature of liquid collection, it was difficult to dispense beer with a clear layer structure using the above-mentioned jigs because of the essential characteristics of the liquid.

  The present invention provides a beverage distribution method in which a plurality of types of beverages are supplied in a layered manner in a container and a layer structure is formed, and the top surface of the first beverage previously injected into the container is finely divided. A method for dispensing a beverage in a container having a layered structure in which a second beverage is fed in a layered manner while suppressing turbulent flow and stirring by a continuous droplet or fine flow through a perforated plate, and It consists of a jig for that purpose.

  In the beverage distribution method of the present invention, the second beverage is turbulent and stirred by continuous droplets or fine flow through the porous porous plate on the upper surface of the first beverage previously injected into the container. In the method of dispensing the beverage into the container, the second beverage is layered while suppressing turbulence and stirring by continuous droplets or fine flow. As a method for supplying the liquid (hereinafter simply referred to as “method for supplying the beverage in a layered manner”), the second beverage supplied through the porous porous plate reaches the liquid level in the container. It is preferable to carry out the adjustment by adjusting the liquid droplets so as to form droplets. As a method for performing such adjustment, as described later, adjusting the size of the pores of the porous porous plate and / or adjusting the head pressure of the second beverage in the pores of the porous porous plate. It is particularly preferable to perform the above.

  The method of supplying the beverage of the present invention in a layered manner can be performed by adjusting the size of the pores of the porous porous plate. In the present specification, “adjusting the size of the pores of the porous porous plate” includes adjusting the size of the porous porous plate with variable pore size, In the perforated porous plate having the same size, selection of an appropriate size is also included.

  The size of the pores of the porous porous plate can be adjusted as appropriate depending on the type of beverage (viscosity, etc.) supplied into the container through the pores, but in order to suppress turbulent flow and stirring, Within a suitable range of the time required to supply the beverage to be fed, it is preferable that the second beverage preferably has a liquid droplet before the second beverage reaches the liquid level in the container. Thus, it is desirable to adjust the size of the pores of the porous porous plate. The shape of the pores of the perforated plate can also be adjusted for this purpose, and in addition to a circle, an ellipse, a rectangle, or the like can be used, and a circle can be preferably used. Note that the above-mentioned quadrangle includes slit-like pores as long and narrow quadrilaterals. The preferred size of the pores is the number of pores, the spacing between the pores, the height from the liquid level of the beverage previously injected into the container to the pore porous plate, the beverage in the pores of the pore porous plate However, from the viewpoint of further suppressing turbulent flow and agitation of the top surface of the previously injected beverage, for example, as the size when the pore shape is circular, the diameter is Within a range of 0.42 to 3 mm, preferably within a range of 0.78 mm to 2.09 mm, more preferably within a range of 0.87 to 2.03 mm, still more preferably within a range of 1.02 to 1.91 mm, More preferably, it is within the range of 1.02-1.72 mm, more preferably within the range of 1.02-1.45 mm, more preferably within the range of 1.02-1.33 mm, and particularly preferably 1.15-1. Can be illustrated as being within the range of 33 mm . Such a suitable diameter can be particularly preferably used when an effervescent beverage such as beer is used as a beverage.

  In addition, the method of supplying the beverage of the present invention in a layered manner can be performed by adjusting the head pressure of the second beverage in the pores of the perforated porous plate, particularly the maximum head pressure. Such water head pressure, particularly maximum water head pressure can be adjusted by adjusting the height, particularly the maximum height, of the second beverage accumulated on the porous porous plate in the present invention. The preferred height of the water head pressure includes the size of the pores, the number of pores, the spacing between the pores, the height from the liquid level of the beverage previously injected into the container to the pore porous plate, etc. Although it can be considered, from the viewpoint of further suppressing the turbulent flow / stirring on the top surface of the previously injected beverage, for example, within the range of 0 to 100 mmAq, preferably within the range of 0 to 90 mmAq, more preferably 0 to 70 mmAq. It is possible to exemplify that it is in the range of 0 to 50 mmAq, more preferably in the range of 0 to 30 mmAq, still more preferably in the range of 0 to 15 mmAq. Such a suitable water head pressure can be particularly suitably used when a sparkling beverage such as beer is used as a beverage. In the present invention, the adjustment of the head pressure of the second beverage includes the case where the second beverage is pressurized. In this case, the fine pressure including the pressurized pressure (excluding atmospheric pressure) is also included. A value obtained by converting the water pressure (excluding atmospheric pressure) of the second beverage in the pores of the perforated plate into water head pressure is defined as the water head pressure in the present invention. Such conversion can be performed based on a conversion formula of “9.8 Pa = 1 mmAq”.

  Moreover, the method of supplying the drink of this invention so that it may become layered can be performed by adjusting with the distribution shape of the pore of a porous porous plate. Examples of the distribution shape of the pores of the porous porous plate include the number of pores of the porous porous plate, the distribution shape, and the spacing between the pores. In addition, with respect to the distribution shape of the pores of the porous porous plate, the pores are symmetric with respect to the center of the porous porous plate from the viewpoint of further suppressing the turbulent flow / stirring on the top surface of the previously injected beverage. It is preferable that the pores be arranged in the shape of the pores, and the pores having a shape distribution along the peripheral surface of the container can be cited as a more preferable pore distribution shape. Here, when the “shape along the circumferential surface of the container” is circular, a circular distribution can be preferably exemplified.

  As a method of supplying the beverage of the present invention in a layered manner, as described above, the pore size, shape, number, distribution shape, pore spacing of the pore porous plate, It is possible to supply the second beverage in a layered manner while suppressing turbulent flow and stirring by combining adjustment of the head pressure of the second beverage in the pores. The adjustment of the size of the pores and the adjustment of the head pressure of the second beverage in the pores of the pore-perforated plate are combined at least so that the second beverage becomes droplets before reaching the liquid level in the container. When adjusted to, turbulent flow and stirring of the second beverage can be particularly effectively suppressed, and such adjustment can be preferably mentioned. The pore size of the porous porous plate is reduced, the number of pores per unit area is reduced, the pores are spaced apart from each other, or the head pressure of the second beverage in the pores of the porous porous plate When (especially the maximum water head pressure) is lowered, when the beverage supplied through the porous porous plate is supplied by continuous droplets or fine flow on the upper surface of the previously injected beverage, the upper surface per unit area Since the kinetic energy given per unit time decreases, the turbulent flow / stirring on the upper surface of the previously injected beverage is further suppressed. However, if the size of the pores is reduced, the number of pores is reduced, or the intervals between the pores are increased, the time required to supply the beverage in a layered manner increases, so the layer structure Can be appropriately adjusted within a range in which the beverage formed can be distributed in the reference container. In addition, when the second beverage is adjusted so as to be a droplet before reaching the liquid level in the container, the beverage supplied through the porous porous plate is a droplet that is continuous with the top surface of the previously injected beverage or When supplied by a fine flow, the kinetic energy given to the upper surface per unit area per unit time can be effectively reduced, and as a result, the turbulent flow and agitation of the upper surface of the previously injected beverage can be reduced. It can be effectively suppressed.

  A person skilled in the art, based on the disclosure of the present specification, at least a combination of the size of the pores of the porous porous plate and the adjustment of the head pressure of the second beverage in the pores, Although it can be adjusted to be a droplet before reaching the liquid level, the diameter of the pore for adjusting the second beverage to become a droplet before reaching the liquid level in the container, The preferable combination with the range of the water head pressure of 2 drinks is specifically mentioned below.

These preferable combinations can also be used particularly suitably when effervescent beverages such as beer are used as beverages.

In addition, about the range of the preferable hydraulic head pressure corresponding to the diameter of any pore within the range of 0.42 to 2.09 mm, which is not described in these preferable combinations, a numerical value calculated from the above preferable combination A range can be mentioned. Here, the diameter of any pore in the range of 0.42 to 2.09 mm that is not described in the above preferred combination is X2 (mm), and among the pore diameters of the above preferred combination, The diameters of the two pores closest to X2 are X1 (mm) and X3 (mm) (where X1 <X2 <X3), and the range of hydraulic head pressure corresponding to X1 in the above preferred combination is Y1 to Y1 ′ ( Considering the case where the range of hydraulic head pressure corresponding to X3 is Y3 to Y3 ′ (mmAq), the lower limit value Y2 and the upper limit in the preferable hydraulic head pressure range Y2 to Y2 ′ (mmAq) corresponding to X2 Examples of the value Y2 ′ include those calculated by the following linear functions.
Y2 = Y1 + (X2-X1) × (Y3-Y1) / (X3-X1):
Y2 ′ = Y1 ′ + (X2−X1) × (Y3′−Y1 ′) / (X3−X1):

As an example of the calculation method, for example, in the combination (ii), when X2 is 0.945 (mm), [X1 mm, Y1 to Y1 ′ mmAq] becomes [0.87 mm, 25 to 90 mmAq] [X3 mm, Y3 to Y3 ′ mmAq] becomes [1.02 mm, 8 to 40 mmAq], and in this case (that is, when X2 is just an intermediate point between X1 and X3),
Y2 = 25 + (0.945−0.87) × (8−25) / (1.02−0.87) = 25−8.5 = 16.5,
Y2 ′ = 90 + (0.945−0.87) × (40−90) / (1.02−0.87) = 90−25 = 65.

  It is preferable to adjust the above-mentioned fine flow length to how many mm or less is the height from the liquid level of the beverage previously injected into the container to the porous porous plate, the second beverage Can be appropriately set depending on the distance from the liquid surface of the second beverage to the porous porous plate when the is finally supplied. For example, from the start to the end of the supply of the second beverage, it is preferable to adjust the fine flow length to be shorter than the distance from the liquid level in the container to the porous porous plate, and the container for supplying the beverage Is a normal beer glass (about 12 to 18 cm in height), it can preferably be mentioned that the fine flow length is adjusted to 40 mm or less, and if the container is larger than that, the fine flow length can be adjusted accordingly. Even when adjusted to a long range, a beverage having a layered structure can be suitably obtained. In the present invention, the height from the liquid level of the beverage previously injected into the container to the perforated porous plate is not particularly limited, but is, for example, in the range of 1 to 20 cm, preferably in the range of 5 to 15 cm. Can be mentioned. In the present invention, the distance from the liquid level of the second beverage to the porous porous plate when the second beverage is finally supplied is not particularly limited, but is, for example, 0.1 to 10 cm, preferably 1 to 8 cm, more preferably 2 to 6 cm can be mentioned.

  In addition, since the second beverage of the upper layer is likely to be mixed with the first beverage of the lower layer, particularly at the beginning of supply, the upper beverage is first supplied through the perforated porous plate in small portions. If a certain level of the inner upper beverage is secured, a method of increasing the supply amount of the upper beverage per unit time can be preferably cited. For example, when the upper beverage starts to be supplied, the second beverage Is adjusted so that it becomes liquid droplets before reaching the liquid level in the container, and if the beverage in the upper layer in the container is secured to a certain level, within a range where a beverage having a layered structure can be obtained There can be mentioned a supply method in which the second beverage reaches the liquid level in the container in a fine flow. In this specification, in order to “adjust” the number of pores, the distribution shape, the spacing between the pores, etc. of the porous porous plate, the elements in the porous porous plate whose adjusting elements are variable In addition to adjusting, it also includes selecting appropriate elements in the porous perforated plate where these adjustments are unchanged.

The preferred number of pores includes the size of the pores, the shape of the pores, the spacing between the pores, the height from the liquid level of the beverage previously injected into the container to the porous pore plate, the pore porosity Since it depends on the water head pressure of the beverage in the pores of the plate, the viscosity of the beverage, etc., it cannot be said unconditionally, but 1 to 20, preferably 5 to 15, more preferably 8 to 12 may be exemplified. it can. The preferred spacing between the pores is the size of the pores, the shape of the pores, the number of pores, the height from the liquid level of the beverage previously injected into the container to the porous porous plate, the pore porosity Since it depends on the water head pressure of the beverage in the pores of the plate, the viscosity of the beverage, etc., it cannot be generally stated, but 5 to 30 mm, preferably 8 to 25 mm, more preferably 10 to 20 mm can be exemplified.

  In the present invention, a plurality of types of beverages are to be distributed. In the present invention, the plurality of kinds of beverages means two or three or more kinds of beverages having no difference in specific gravity or two or more kinds of beverages having a difference in specific gravity, and preferably have a difference in specific gravity. 2 types or 3 types or more of beverages including 2 types or 3 types or more of beverages, and having a specific gravity difference of at least 0.001 g / ml or more, preferably 0.004 g / ml or more between any 2 types including. The type of the beverage is not particularly limited, and may be an alcoholic beverage or a soft drink, but preferably applicable beverages include beer, sparkling liquor, beer-like beverages, other miscellaneous alcoholic beverages, liqueurs, and soft drinks. Etc. can be mentioned as beverages to which more preferably can be applied. Preferred examples of the soft drink include soft drinks such as cola, tomato juice, and milk. In addition, from the viewpoint of obtaining a beverage having a visually beautiful layer structure, the plurality of types of beverages preferably have a color difference, but may not have a color difference. Here, the color means one or more of hue, saturation, and brightness. In addition, the specific gravity of a drink can be measured by a well-known method. Examples of the measuring method include the method described in JIS Z8804 “Method for measuring density and specific gravity of liquid”.

  The method of dispensing a beverage having a layer structure according to the present invention includes a jig container part comprising a peripheral wall and a jig bottom made of a porous porous plate, and the jig container part for placing the jig container part on the upper part of the container. Even if it is a beverage of relatively specific gravity, it is easy and reliable for anyone, even if it is a beverage with a relatively close specific gravity, using a jig that consists of a support and is used to distribute beverages with a layered structure. In addition, the beverage having a layered structure can be dispensed into the container.

  Hereinafter, a jig for dispensing a beverage having the layer structure of the present invention into a container (hereinafter simply referred to as “the jig of the present invention”) will be described with reference to FIG. The jig of the present invention is a jig for supplying a plurality of types of beverages in a layered manner in a container, and for distributing the beverage having a layered structure into the container, as shown in FIG. Further, a jig container part composed of a peripheral wall (1-1) and a jig bottom part (1-2) made of a porous porous plate, and a support part (2 for placing the jig container part on the upper part of the container -1).

  The jig container part is composed of an outer peripheral wall (1-1) and a jig bottom part (1-2) made of a porous porous plate, and the jig container part has a certain amount injected into the container through the jig. It has a capacity to accommodate beverages. The shape of the jig container is not particularly limited as long as the beverage can be put into the jig container and the beverage can be made into a continuous liquid droplet or a fine flow through the porous porous plate. However, since it usually has a circular mouth such as a mug or glass, the jig bottom is preferably circular in plan view, and the outer peripheral wall bottom is preferably circular in plan view accordingly. The outer peripheral wall preferably extends in a tapered shape from the bottom of the outer peripheral wall to the top of the outer peripheral wall. The jig bottom may not be a flat surface and may include a concave portion or a convex portion, but it is preferably a flat surface in order to apply an average hydraulic pressure to the porous porous plate.

  The height of the outer peripheral wall of the jig container is appropriately adjusted according to the capacity of the beverage to be injected into the container and the maximum water head pressure of the second beverage in the pores of the porous porous plate. However, if the outer peripheral wall is raised, the capacity in the jig container increases, and in order to pour the second beverage into the jig container, a large amount is accommodated in the container, and the frequency of pouring the beverage into the jig container part is reduced. The operation of the distribution method becomes simpler. However, since the height of the beverage that can be put in the jig container also increases when the outer peripheral wall is raised, if the second beverage is put in the jig container more than necessary, the pore porous plate in the jig container Depending on the viscosity of the beverage, the water head pressure of the beverage in the pores will increase, and as a result, the momentum of the fine flow of the beverage supplied through the porous porous plate will increase and the fine flow length will become too long. obtain. Therefore, it is preferable that the height of the outer peripheral wall is appropriately adjusted within a range in which the beverage having the layer structure can be distributed in the citation container. The preferred height of the outer peripheral wall is the size of the pores, the shape of the pores, the number of pores, the spacing between the pores, from the liquid level of the beverage previously injected into the container to the porous porous plate. Since it depends on the height, the viscosity of the beverage and the like, it cannot be said unconditionally, but it is within the range of 10 to 100 mm, preferably within the range of 10 to 50 mm, more preferably within the range of 15 to 45 mm, more preferably 20 to. A range of 40 mm can be exemplified. The jig container part preferably further includes a spout for pouring the beverage remaining in the jig container part and / or its foam into the container. In addition, the shape and size of the jig bottom can be appropriately adjusted in accordance with the shape and size of the container.

  The pore perforated plate has a plurality of pores, and the size, shape, number, distribution shape, and pores of the pores can be used as long as the beverage can be a continuous droplet or a fine flow through the pores. There is no particular limitation on the interval of the. The preferred size, preferred shape, preferred number of pores, and preferred spacing between the pores can be appropriately determined according to the properties (viscosity, etc.) of the beverage injected into the container through the jig. As a preferable distribution shape of the pores, from the viewpoint of further suppressing the turbulent flow / stirring on the top surface of the previously injected beverage, it is arranged so that the pores are targeted with respect to the center of the porous porous plate. Preferably, in the case of a circular jig bottom, it is preferably arranged in a circular shape along the outer peripheral end. The porous porous plate may have only pores having the same size and shape, or may have two or more different sizes and shapes of pores.

The jig of this invention has a support part (2-1) for mounting a jig container part on the upper part of a container.
The shape of the support portion is not particularly limited, and examples thereof include a plate shape. However, as shown in FIG. 1, the jig container portion in a plan view so that the jig container portion can be placed on the upper portion of the container. The thing of the structure extended toward the outer side from can be mentioned. Moreover, a design change can be appropriately made as a structure that can be stably placed on the upper part of the container based on the structure. The container fitting groove (2-1-1) is not particularly limited as long as it is a groove that fits in the upper part of the container so that the jig can be stably placed on the upper part of the container. It is preferable that the groove has a wide width so that In this case, the container fitting groove (2-1-1) does not fit in the upper part of the container without a strict sense, but for convenience, such an aspect is also included in the “fitting” in the present invention. In addition, when installing a support part in two places, you may give a wide width | variety only to the container fitting groove | channel of one support part.

  The support part (2-1) of the jig of the present invention includes a container fitting groove (2-1-1) for stably placing the jig on the upper part of the container, and a jig holding the jig to place the jig on the upper part of the container. A gripping part (2-2) for placing or removing can be provided. The gripping part may be formed integrally with a support part for placing on the upper part of the container, and both may be combined to form a support. Further, the support portion (2-1) can be provided with a separation groove for preventing a droplet or fine flow of the second beverage from being transmitted to the support portion. As long as the separation groove is a groove that can prevent the droplet or fine flow of the second beverage from being transmitted to the support portion, its structure can be changed as appropriate. The provided structure can be mentioned as a preferable structure. Moreover, the cover part which covers the opening part of a container can be provided in the jig container part and / or support part of this invention. Such a lid is preferable because it can prevent the beverage from flowing into the container when the second beverage is excessively poured into the jig container and overflows. Such a lid portion may not cover the entire surface of the opening of the container, but preferably covers the entire surface. Note that such a lid may be provided in the gripper, or the lid itself may be used as the gripper.

  Examples of suitable methods for using the jig of the present invention include the following methods. Of the prepared multiple types of beverages, the beverage having the largest specific gravity is normally poured into the container to form the first layer (lowermost layer). The jig of the present invention is placed in the opening of the container. When a beverage having the next highest specific gravity (the second layer beverage) is poured into the jig container part of the jig of the present invention after the first layer beverage, the droplets in which the second layer beverage continues through the porous porous plate or It is supplied into the container by a fine flow (preferably so that it becomes a droplet before the second layer of beverage reaches the liquid level in the container), and the second layer is formed on the upper surface of the first layer of beverage in the container. Is formed. When the same pouring process as the second layer is repeated until all the prepared types of beverage are used, a beverage having the same number of layer structures as the prepared type is obtained. For this reason, the first beverage in the present invention is particularly preferably a beverage having a higher specific gravity, and the second beverage is particularly preferably a beverage having a lower specific gravity. In the present invention, whether the beverage previously injected into the container is one layer or two or more layers, the beverage supplied to the upper surface of the beverage through the porous porous plate corresponds to the second beverage, The beverage directly below the second beverage corresponds to the first beverage. Therefore, when there are three or more types of beverages used in the present invention, the first beverage and the second beverage do not correspond to one type of beverage, respectively, and each corresponds to a plurality of types of beverage. Become. For example, considering a case where a beverage having a three-layer structure is prepared by pouring three kinds of beverages P, Q, and R in this order, first, P is injected into the container as a first beverage, and Q is placed thereon. Is supplied as a second beverage. Next, the Q is now the first beverage, on which R is supplied as the second beverage.

  In addition, the jig container portion of the jig of the present invention is provided with a mark such as a line representing how many mm or less the fine flow length can be made if the second beverage poured into the jig container portion is below this height. The mark is preferably provided, and as such a mark, for example, a mark that can make the fine flow length about 60 mm or less, a mark that can make the fine flow length about 40 mm or less, and the second beverage are poured out from the pores The mark which can be made into a droplet at the time of doing can be mentioned preferably. The height of the jig container portion to which these marks are to be applied is a preferable combination of the aforementioned pore diameter and the range of the head pressure of the second beverage, and a numerical range calculated from such a preferable combination. It can be set by referring.

  Specifically, the height (mm) of the mark indicating that the fine flow length can be 60 mm or less is the head pressure (2) of the second beverage selected or calculated from the combination (i) according to the diameter of the pores. The upper limit value in the range of mmAq) can be a value (mm) divided by the specific gravity of the second beverage, and the height (mm) of the mark indicating that the fine flow length can be 40 mm or less is thin. The upper limit of the range of the head pressure (mmAq) of the second beverage selected or calculated from the combination (ii) according to the diameter of the hole may be a value (mm) divided by the specific gravity of the second beverage. The height (mm) of the mark indicating that the second beverage can be formed into a droplet at the time when the second beverage is dispensed from the pore is selected or calculated from the combination (iii) according to the diameter of the pore. Value obtained by dividing the upper limit value of the water head pressure (mmAq) of two beverages by the specific gravity of the second beverage (m It can be). For example, considering a mark that allows the fine flow length to be 40 mm or less with a pore diameter of 1.02 mm, the water head pressure needs to be 40 mmAq or less, so that the specific gravity of the second beverage is 1.1. In this case, a mark can be placed at a height of 36.4 mm (40 / 1.1) of the jig container.

  EXAMPLES The present invention will be described in detail below with reference to examples, but the present invention is not limited to these examples.

[Jigs for dispensing beverages in containers]
A specific example of the jig of the present invention will be described with reference to FIG. As shown in FIG. 1, the jig of the present invention comprises a jig container part comprising a peripheral wall (1-1) and a jig bottom part (1-2) made of a porous porous plate, and the jig container part at the upper part of the container. A jig for supplying a plurality of types of beverages in a layered manner in a container and distributing the beverages in a layered structure in a container, comprising a support part (2-1) for placing on the container is there. The jig bottom (1-2) has a circular planar shape in plan view. The outer peripheral wall (1-1) extends in a taper shape from the outer peripheral wall bottom (1-1-2) to the outer peripheral wall top (1-1-1). Plural pores (1-3) in the perforated plate of the jig bottom (1-2) are arranged in a circular shape at regular intervals along the outer peripheral edge of the circular jig bottom (1-2) Has been.

  The jig container part includes a support part (2-1) for placing the jig container part on the upper part of the container at the outer peripheral wall bottom part (1-1-2). The support portion (2-1) extends outward from the jig container portion at two locations facing the center of the jig container portion in plan view. The support part (2-1) further includes a grip part (2-2) for gripping the jig and placing or removing the jig on the upper part of the container, and the support part (2) ) Is formed. The support part (2-1) includes a container fitting groove (2-1-1) for stably placing the jig on the upper part of the container, and a droplet or a fine flow that has passed through the pores. It has a separate groove (2-1-2) to prevent it from being transmitted to

  The container fitting groove (2-1-1) and the separation groove (2-1-2) are attached only to the support part (2) on one side (III in FIG. 1). (2-1-1) and the separation groove (2-1-2) are also provided in the support portion (2) on the opposite side. The height of the jig container was 29 mm, the diameter of the jig bottom was 45 mm, and the diameter when the outer peripheral wall top was viewed in plan was about 58 mm. The pores were tapered toward the container (taper angle 20 °), and the diameter of the hole at the tip was 1 mm.

[Distribution test 1 of beverage having a layered structure]
Using the jig of the present invention described in Example 1, a beverage distribution test for a beverage having a layered structure was performed. Such a test was conducted by the following method. A glass glass (height 15.1 cm) is prepared as a drinking container, black beer (specific gravity 1.010) is prepared as the first beverage to be poured first into the drinking container, and a normal amber colored as the second beverage Beer (specific gravity 1.008) was prepared. All beverages used were kept in the refrigerator for 1 day before the start of the experiment. After the black beer was poured into the glass up to half, the jig of the present invention was placed on top of the glass, and ordinary beer was poured into the jig container. Normal beer was supplied into the glass through a plurality of pores (1-3) in the jig bottom (1-2). It was visually confirmed whether black beer and normal beer were divided into two layers in the glass.

  When a test was performed using the jig of the present invention described in Example 1 having 10 pores having a diameter of 1 mm, a two-layer beer in which a black beer layer and a normal beer layer were clearly separated was produced. (See Fig. 2).

  Next, in order to investigate the influence of the diameter of the pores, in the jig of the present invention described in Example 1, the same test as before was performed using a jig in which the diameter of the pores was not 1 mm but 1.5 mm. went. As a result, it was possible to produce a two-layer beer with the jig of the present invention having pores having a diameter of 1.5 mm, but the jig of the present invention having pores having a diameter of 1 mm was used for the interface between the two layers. If you were there was more clearly divided. Therefore, the same test as described above was performed using a jig in which the number of pores of the jig of the present invention having pores having a diameter of 1.5 mm was reduced from 10 to 8 or 6. As a result, in both cases of 8 pores and 6 pores, it was possible to produce a two-layer beer in which the black beer layer and the normal beer layer were clearly separated. From this result, it was found that even if the diameter of the pores of the jig of the present invention is slightly increased, a two-layer beer in which the layers are clearly separated can be produced by adjusting by reducing the number of pores. . That is, even if the diameter of the pores of the jig of the present invention is slightly increased, if adjusted by reducing the number of pores, etc., the beverage supplied through the porous perforated plate is the top surface of the previously injected beverage. When supplied by continuous droplets or fine flow, the kinetic energy given to the upper surface per unit area per unit time can be reduced, and the turbulent flow and agitation of the upper surface of the previously injected beverage is suppressed. Thus, it has been found that a beverage having a layer structure can be distributed in a container such as a drinking container.

[In-container distribution test for beverages with layered structure 2]
Using the jig of the present invention described in Example 1, a beverage distribution test in which a layered structure was formed was further performed. For this test, the jig of the present invention described in Example 1 having 10 pores having a diameter of 1 mm was used and the same method as in Example 2 was performed. At that time, black beer (first beverage) from the bottom of the jig at the time when normal beer (second beverage) starts to be poured into the glass (height 15.1 cm) (hereinafter referred to as “injection start time”). The height to the upper surface (hereinafter referred to as “injection height”) was 70 mm, and the diameter of the upper surface of the black beer at the start of the injection was also 70 mm. Ordinary beer was poured several times to the extent that the jig container of the jig of the present invention was almost filled. As a result, the interface between the two beers was not disturbed until the liquid level of the normal beer being poured rose to about 20-30 mm up to the bottom of the jig, but the liquid level of the normal beer further increased and the bottom of the jig When approaching, the interface between the two beers was disturbed and mixed.

  When observing this series in detail, normal beer poured from the jig of the present invention is a fine flow, not a droplet, until it falls about 20-30 mm from the pores at the bottom of the jig, It turned out that it changed into the droplet at the front-end | tip part, and was falling further (refer FIG. 3). Also, when normal beer is poured into a glass and the liquid level approaches the bottom of the jig, the normal beer poured into the liquid surface changes from a droplet to a fine flow, thereby causing the normal beer liquid level It was found that convection occurred in the vicinity, the convection reached the interface between normal beer and black beer, and the interface was disturbed to cause mixing of both beers.

  Next, the same test as before, this time reducing the amount of normal beer poured into the jig container part at once and lowering the head pressure of normal beer in the pores, normal beer even directly under the pores Became a droplet, and a two-layer beer in which a black beer layer and a normal beer layer were clearly separated could be produced.

  Even when the number of pores of the jig of the present invention was changed from 10 to 1, the same result was obtained. That is, if the amount of normal beer poured into the jig container part is large, both beers are mixed at the end of injection, and if the amount of normal beer poured into the jig container part is reduced, clean two-layer beer Was able to be produced. These test results did not change even in a similar test using a glass having a shape different from that of the previous glass (wine glass: height 18.6 cm) (the diameter of the upper surface of black beer at the start of pouring is 58 mm).

  From the series of test results of Example 3, whether or not the turbulent flow and stirring of the beverage in the container can be suppressed and the two-layer beer can be produced depends on the injection height and the number of pores at the start of the second beverage injection. And the distribution, the supply flow rate per unit time of the second beverage, etc., but it is particularly important whether the second beverage is a fine flow or a droplet when reaching the liquid level in the container, It was shown that the size of the pores and the water head pressure of the second beverage in the pores are important for whether the second beverage reaches the liquid level in the container. . If it is a droplet when the second beverage reaches the liquid level in the container, the turbulent flow / stirring of the beverage in the container can be suppressed. When reaching the liquid level, most of the kinetic energy is absorbed as vibrations on the liquid surface, but when a continuous flow reaches the liquid level as a fine flow, it is converted into vibrations on the liquid surface and absorbed. This is considered to be due to the fact that both beverages are mixed because the amount of energy that is applied is small and the kinetic energy that is retained even after the aforementioned flow reaches the interface between the beverages.

[Effects of pore diameter and water head pressure on fine flow length]
In order to examine the influence of the diameter of the fine pores and the water head pressure in the fine pores on the vertical length (fine flow length) of the fine flow of the second beverage poured out from the fine pores, the fine pores of the jig of the present invention The fine flow length was measured by varying the diameter of the water and the water head pressure in the pores. Such a test was conducted by the following method. A normal beer similar to that used as the second beverage in Example 2 was prepared. As this normal beer, what was put into the refrigerator for 1 day before the experiment start was used. As the jig of the present invention, one having one pore having each diameter (0.30 mm to 2.09 mm) listed in Table 1 described later was prepared. Moreover, in this jig, the jig container part was extended in the height direction so that the water head pressure in the pores could be increased to 100 mmAq. Such a jig of the present invention was fixed above the glass with a stand and a clamp. Normal beer is poured into the jig container, and the vertical length of the fine flow from the fine flow of normal beer poured from the pores to the separation of the droplet (the length from the bottom of the jig to the tip of the fine flow) ("Lmm") (see Fig. 4) was visually measured using a ruler. The results are shown in Table 1. In addition, “0” in the table indicates that normal beer was a droplet at the time of pouring from the pores, and “x” indicates that normal beer oozes out from the pores, but just below the pores. It shows that it is no longer in a state of being separated as a droplet from

  From the results in Table 1, when the head pressure in the pores is constant, the fine flow length increases as the diameter of the pores increases. When the diameter of the pores is constant, the head pressure in the pores increases. It turned out that the fine flow length tends to become longer.

  The present invention relates to a method of distributing a beverage in a container in a layered manner when the beverage is distributed and served in a container such as a drinking container at the time of drinking or in a restaurant, etc., and the layer structure of the beverage in the container Provide jigs to perform the distribution. In particular, the method for dispensing a beverage having a layered structure according to the present invention into a container requires skill in the technology even if the beverage has a relatively similar specific gravity by using a jig for carrying out the dispensing.
