Description

  The present invention relates to a carbonated beverage manufacturing apparatus.

  Carbonated beverages such as beer and soda water are not only filled and provided in cans or plastic bottles, but are sometimes poured from a beer server or drink server into a cup or the like. In this case, immediately before being poured into the vessel, the cooled water and beverage stock solution and the carbon dioxide gas supplied from the carbon dioxide cylinder are mixed to produce a carbonated beverage. However, there is a problem that it is difficult to handle the carbon dioxide cylinder.

  As a method for solving this, Patent Literature 1 listed below discloses a gas hydrate production apparatus for producing gas hydrate by bringing carbon dioxide and water into contact with each other in a tank, and a separation apparatus for separating the gas hydrate from water. A gas hydrate storage tank for storing the gas hydrate from which water has been separated, a carbonated water production tank for producing carbonated water, and a beverage storage tank, wherein the gas hydrate in the storage tank is converted into the carbonated water. A carbonated beverage production apparatus is described in which carbonated water is produced by supplying to a production tank, and the carbonated water is taken out and mixed with a beverage stock solution taken out from the beverage storage tank. Yes.

Patent Document 2 below describes that carbon dioxide gas hydrate contains 50 m ³ carbon dioxide gas and 0.8 m ³ water in 1 m ³ gas hydrate at about 0 ° C. .
JP 2005-224146 A JP-A-2005-305128

  However, the apparatus described in Patent Document 1 requires a gas hydrate production apparatus, a separation apparatus, a gas hydrate storage tank, a carbonated water production tank, and a beverage storage tank. These apparatuses are used in combination. Therefore, it is expensive, and it is difficult or impossible to carry compared to a beer server or a drink server. Further, as the remaining amount of carbonated water in the carbonated water production tank and the remaining amount of beverage stock solution in the beverage storage tank decrease, the supply amount of carbonated water and the supply amount of beverage stock solution decrease, and the carbonated water supply amount The ratio of the supply amount of the beverage stock solution, that is, the mixing ratio of the carbonated water and the beverage stock solution in the carbonated beverage cannot be kept constant, but no means for solving this is described.

  An object of the present invention is to provide a carbonated water production apparatus that is easy to carry and has a simple structure capable of continuously producing a carbonated drink containing carbonated water and a beverage stock solution at a predetermined mixing ratio.

  In the present invention, carbon dioxide hydrate is used to produce carbonated water. Carbon dioxide hydrate decomposes into carbon dioxide and water over time. Note that the volume of carbon dioxide at 50 ° C. and normal pressure is 50 times that of carbon dioxide hydrate and that of water is 0.8 times that of carbon dioxide hydrate (see Patent Document 2). In a system in which carbon dioxide and water coexist, carbon dioxide is dissolved in water. When the pressure (partial pressure) of carbon dioxide is high, a large amount of carbon dioxide is dissolved in water to produce carbonated water.

The carbonated beverage production apparatus of the present invention is a container entirely covered with a heat insulating material, a pressure control valve provided at the top of the container, and provided in the container, and can place carbon dioxide hydrate, And a support plate having a hole through which carbonated water formed by dissolving carbon dioxide in water generated by decomposition of the carbon dioxide hydrate, and an openable and closable carbonated water outlet provided at the lower portion of the container. The carbonated water supply device and another container, and one end is attached to a position not immersed in the beverage stock solution contained in the container, and the other end is higher than the support plate of the carbonated water supply device. A conduit that is attached to the container of the carbonated water supply apparatus and passes through the inside of the container of the carbonated water supply apparatus and the interior of the container 18 and the interior of the other container, and an openable / closable undiluted solution provided at the lower part of the other container With exit Charge and a starting solution feed device, and carbonated water supplied from said water outlet, and characterized by being configured to make the carbonated beverages by mixing a beverage concentrate which is supplied from the stock outlet.

The apparatus of the present invention preferably includes a heating means for melting ice formed by freezing water generated by decomposition of carbon dioxide hydrate in the container. This is, for example, an electric heater provided with a power switch that is electrically connected to a power source provided outside the container.

  Moreover, the said beverage undiluted solution supply apparatus may be one, and may be provided with two or more.

  The apparatus of the present invention includes a carbonated water supply device in which a pressure control valve, a support plate, and a water outlet are provided in a container entirely covered with a heat insulating material, and a beverage stock solution in which a conduit and a concentrate outlet are provided in another container. Since it is a combination with a device, it is formed small and lightweight. That is, all the means required for producing carbonated water from carbon dioxide hydrate and the means for supplying carbonated water and beverage stock solution are contained in two containers, so the configuration is simple and easy to carry An apparatus for producing carbonated beverages is provided.

  Moreover, since the conduit | pipe provided in the other container of the beverage undiluted solution supply device leads to the inside of the container of the carbonated water supply device and the other container of the beverage undiluted solution supply device, And the pressure inside another container of the beverage stock solution supply device becomes equal. Thereby, the supply amount of carbonated water from the water outlet of the carbonated water supply device and the supply amount of beverage stock solution from the stock solution outlet of the beverage stock solution supply device do not depend on the remaining amount of carbonated water and the remaining amount of beverage stock solution. Since it always becomes equal, the carbonated beverage manufacturing apparatus which can manufacture continuously the carbonated beverage containing carbonated water and a drink undiluted | stock solution with a predetermined | prescribed mixing ratio is provided.

In the apparatus of the present invention, the inside of the container of the carbonated water supply apparatus can be maintained at a predetermined temperature and a predetermined pressure. This is realized by a heat insulating material and a pressure control valve provided in the container of the carbonated water supply device. The predetermined temperature and the predetermined pressure are, for example, −20 ° C. to −10 ° C. and 2 kg / cm ² (that is, 0.2 MPa). If this condition is maintained, for example, carbon dioxide hydrate is stored in the carbonated water supply container for about 2.5 days when the outside air temperature is 30 ° C and for about 8 days when the outside air temperature is 0 ° C. During this period, carbonated beverages can be produced. The heat insulating material that can be maintained at -20 ° C to -10 ° C is, for example, foamed polyurethane having a thickness of 2 cm.

  When carbon dioxide hydrate is decomposed at -20 ° C to -10 ° C, the generated water becomes ice after a while and adheres to the surrounding carbon dioxide hydrate and support plate. However, as time goes on, the ice melts into water by heat supplied from outside the container.

  Drawing 1 is a figure showing the whole carbonated drink manufacturing device composition of an example. The carbonated beverage production apparatus 1 includes a carbonated water supply device 10 and a beverage stock solution supply device 20. One beverage undiluted solution supply device 20 may be provided, or a plurality (two in FIG. 1 indicated by 20A and 20B) may be provided.

  The carbonated water supply device 10 includes a container 11, a heat insulating material 12, a pressure control valve 13, a shielding plate 14, and a water outlet 15.

  The container 11 is composed of a stainless steel tank having a diameter of about 300 mm, a height of about 510 mm, and a thickness of about 1 mm, and has a volume of about 30 liters and a weight of about 4 kg. The whole is covered with the heat insulating material 3. The heat insulating material 12 is made of foamed polyurethane having a thickness of 2 cm, whereby the temperature inside the container 18 is maintained at -20 ° C to -10 ° C.

A lid 11 a and a pressure control valve 13 are provided on the top of the container 11. The carbon dioxide hydrate 2 can be supplied into the container 11 by removing the lid 11a and the lid portion 12a of the heat insulating material covering the lid 11a. The gas inside the container 18 is discharged out of the container 11 by the pressure control valve 13, and the container inside 18 is maintained at a predetermined pressure, for example, 2 kg / cm ² .

  In the container 11, a shielding plate 14 having a hole 14 a through which water passes (but carbon dioxide hydrate 2 does not pass) is provided as a support plate on which the carbon dioxide hydrate 2 is placed. The size of the hole 14a is preferably smaller than the carbon dioxide hydrate 2 and about 5 mm in diameter. Note that the shielding plate 14 may be a metal net having a similar mesh, for example, a copper net excellent in thermal conductivity. Further, it is desirable to place about 11 kg of carbon dioxide hydrate 2 on the shielding plate 14. Then, the carbonated water 3 accumulates under the shielding plate 14. This portion where the carbonated water 3 accumulates, that is, the volume under the shielding plate 14, is preferably about 10 liters. In addition, in order to use the carbonated beverage production apparatus 1 before the carbonated water 3 generated by decomposition of the carbon dioxide hydrate 2 is collected, about 6 liters of carbonated water 3 separately prepared under the shielding plate 14 is previously prepared. It is desirable to store it.

  On the shielding plate 14, an electric heater (heater) 34 that is electrically connected to a power source 35 provided outside the container 11 via a power switch 36 is provided. By turning on the power switch 36, the electric heater 34 is energized and can be heated to about 1 ° C.

  At the lower part of the container 11, one end communicates with the container 11, the other end serves as the water outlet 15, and a conduit 16 having a cock valve 32 and a flow rate adjusting valve 17 is provided in the middle. By opening the cock valve 32, the carbonated water 3 accumulated at the bottom of the container 11 can be taken out of the container 11 from the water outlet 15. Further, the flow rate of the carbonated water 3 coming out of the water outlet 15 can be controlled by opening and closing the flow rate adjusting valve 17.

  The carbon dioxide hydrate 2 used in the examples is manufactured by, for example, the gas hydrate manufacturing apparatus described in Patent Document 1.

  In the example, as time passes, the carbon dioxide hydrate 2 decomposes into carbon dioxide and water in the container interior 18. The generated water becomes ice after a while because the temperature inside the container 18 is low, and adheres to the surrounding carbon dioxide hydrate 2, the shielding plate 14, and the like. Over time, the ice melts into water by the heat supplied from the outside of the container 11 and the electric heater 34. Then, since the pressure inside the container 18 is increased by the generated carbon dioxide, a larger amount of carbon dioxide is dissolved in water than under normal pressure, and carbonated water 3 is generated. For example, about 10 liters of carbonated water 3 is produced from about 11 kg of carbon dioxide hydrate 2. The carbonated water 3 accumulates at the bottom in the container 11 through the hole 14 a of the shielding plate 14. When the cock valve 32 is opened, the carbonated water 3 comes out from the water outlet 15 as described above.

  On the other hand, the beverage stock solution supply device 20 includes a stock solution container 21, a stock solution outlet 25, and a gas conduit 29. In FIG. 1, the stock solution container 21 </ b> A and the stock solution container 21 </ b> B are described. However, these are hereinafter referred to as “stock solution container 21” unless it is necessary to distinguish them.

  The stock solution container 21 desirably has a required volume according to the amount of beverage stock solution required for the carbonated beverage to be produced. For example, when a carbonated beverage having a mixing ratio of carbonated water and beverage stock solution of 1: 0.25 is manufactured, the stock solution container 21 has a volume of about 4 liters (because the carbon dioxide hydrate 2 of about 11 kg is used). The generated carbonated water 3 is about 10 liters, and the carbonated water 3 stored in the lower part of the container 11 is about 6 liters, so the total amount of carbonated water 3 is about 16 liters). . Moreover, when more than 4 liters, the frequency | count of supplying the drink stock solution 4 to the stock solution container 21 can be reduced.

  The stock solution container 21 is made of a stainless steel tank having a diameter of about 160 mm, a height of about 200 mm, and a thickness of about 1 mm, and has a volume of about 4 liters and a weight of about 1 kg. By removing the lid 21 a provided on the upper part of the stock solution container 21, the beverage stock solution 4 can be supplied into the stock solution container 21. The beverage stock solution 4A in the stock solution container 21A and the beverage stock solution 4B in the stock solution container 21B may be the same beverage stock solution or different beverage stock solutions.

  A gas conduit 29 that leads to the container interior 18 is provided at a position higher than the shielding plate 14 of the carbonated water supply device 10 at a position where the beverage stock solution 4 in the stock solution container 21 is not immersed. Since the gas (carbon dioxide) in the container interior 18 moves through the gas conduit 29 to the stock solution container interior 28, the pressure in the stock solution container interior 28 becomes equal to the pressure in the container interior 18. When a plurality of stock solution containers 21 (21A and 21B) are provided, each of the gas conduits 29A and 29B may be directly communicated with the container interior 18, or the joint 30 may be used to connect the interior 18 of the container. The gas conduit 29B may be connected to the gas conduit 29A leading to

  At the lower part of the stock solution container 21, one end communicates with the stock solution container 21, the other end serves as a stock solution outlet 25, and a stock solution conduit 26 having a stock solution cock valve 33 and a stock solution flow rate adjustment valve 27 is provided in the middle. It has been. By opening the stock solution cock valve 33, the beverage stock solution 4 in the stock solution container 21 can be taken out of the stock solution container 21 from the stock solution outlet 25. Further, the flow rate of the beverage stock solution 4 coming out from the stock solution outlet 25 can be controlled by opening and closing the flow rate adjusting valve 27.

  When the cock valve 32 and the stock solution cock valve 33 are simultaneously opened and the carbonated water 3 and the beverage stock solution 4 coming out of the water outlet 15 and the stock solution outlet 25 are poured into the cup 31, the carbonated water 3 and the beverage stock solution 4 Are mixed to form a carbonated beverage 5.

At this time, the mixing ratio of the carbonated water 3 and the beverage stock solution 4 contained in the carbonated beverage 5 to be produced is always constant without depending on the remaining amount H ₁ of the carbonated beverage 3 and the remaining amount h ₁ of the beverage stock solution 4. It becomes.

  Hereinafter, it will be described that the mixing ratio between the carbonated water 3 and the beverage stock solution 4 contained in the carbonated beverage 5 is constant.

_{P v → P L, p v} → p L, P g → P G, p g → p G, P w → P W, p w → p W
The supply amount Q (m ³ / s) of the carbonated water 3 from the water outlet 15 is expressed by the following equation.

Q = πR ² × V (1)
R: Inner diameter of conduit 16 (m)
V: Average flow rate of carbonated water (m / s)
Here, the pressure loss P _L (MPa) generated when the carbonated water 3 flows in the conduit 16 is expressed by a function F of the following equation.

P _L = F (R, V, Μ, D, Ζ) (2)
P _L : Pressure loss (MPa) generated when carbonated water 3 flows in the conduit 16
Μ: Viscosity of carbonated water 3 (Pa · s)
D: Density of carbonated water 3 (kg / m ³ )
Ζ: Factor relating to the shape of the conduit 16 Note that the factor に 関 す る relating to the shape of the conduit 16 is the length of the conduit 16, the shape of the inlet from the container 11 to the conduit 16, the shape of the elbow of the conduit 16, the flow control valve 17, It is determined by the shape of the cock valve 32 or the like.

  Therefore, the average flow velocity V (m / s) of the carbonated water 3 is expressed by the function H of the following equation.

V = H (P _L , R, Μ, D, Ζ) (3)
Substituting equation (3) into equation (1) gives
_{^{Q = πR 2 × H (P}} L, R, Μ, D, Ζ) ... (4)
It becomes. Here, the pressure loss P _L (MPa) is expressed by the following equation.

P _L = P _G −P ₀ + P _W = P _G −P ₀ + Dg (H ₁ + H ₂ ) (5)
P _G : Pressure inside the container 18 (MPa)
P ₀ : Atmospheric pressure (MPa)
P _W : Pressure caused by the remaining amount of carbonated water 3 (MPa)
g: Standard gravity acceleration (m / s ³ )
H ₁ : Height from the surface of carbonated water 3 to the bottom of container 11 (m)
H ₂ : Height from the bottom of the container 11 to the water outlet 15 (m)
The value of each variable is as follows. The pressure P _G inside the container 18 is 0.2 MPa, as described above. The atmospheric pressure P ₀ is 0.1013 MPa. The density D of the carbonated water 3 is 0.001 kg / m ³ assuming that it is the same as that of water. From the water surface of the carbonated water 3 to the bottom of the container 11 height, i.e. the remaining amount H ₁ of the carbonated water 3 is the maximum 0.14 m (since carbonated water 3 produced by the decomposition of carbon dioxide hydrate 2 in 10 liters However, the value becomes smaller during decomposition of the carbon dioxide hydrate 2 or after a part of the carbonated water 3 is used (that is, from the water outlet 15). The height H ₂ from the bottom of the container 11 to the water outlet 15 depends on the installation location of the water outlet 15, but for example, H ₂ = 0.03 m. Substituting each value into equation (5)
P _L = 0.2−0.1013 + 0.001 × 9.807 × (H ₁ +0.03) (6)
It becomes. Since _{H 1} is _P G -P ₀ »D from not more than _{0.14 m (H 1 + H 2} ), can ignore the terms of equation (5) D _(H 1 + _{H 2)} Equation (2) can be expressed as P _L = P _G −P ₀ (7)
Can be approximated. Therefore, (7) from the equation, the pressure loss P _L generated by carbonated water 3 flows through the conduit 16, the height H ₁ to the bottom of the container 11 from the water surface of the carbonated water _3, namely the carbonated water 3 residues without depending on the amount, it can be seen that depends only on the pressure P _G in the vessel interior 18.

Here, substituting equation (7) into equation (4),
Q = πR ² × F (P _G , P ₀ , R, Μ, D, Ζ) (8)
It becomes.

Similarly, the supply amount q (m ³ / s) of the beverage stock solution 4 from the stock solution outlet 25 is expressed by the following equation.

q = πr ² × v (9)
r: Inner diameter of stock solution conduit 26 (m)
v: Average flow rate of beverage stock solution 4 (m / s)
Here, the pressure loss p _L (MPa) generated by the beverage stock solution 4 flowing through the stock solution conduit 26 is expressed by the function f of the following equation.

p _L = f (r, v, μ, d, ζ) (10)
p _L : Pressure loss (MPa) generated by the beverage stock solution 4 flowing in the stock solution conduit 26
μ: Viscosity of beverage stock solution 4 (Pa · s)
d: Density of beverage stock solution 4 (kg / m ³ )
ζ: coefficient relating to the shape of the conduit 26 Note that the factor ζ relating to the shape of the conduit 26 is the length of the conduit 26, the shape of the inlet portion from the concentrate container 21 to the conduit 26, the shape of the elbow portion of the conduit 26, and the concentrate flow rate regulating valve. 27, determined by the shape of the stock cock 33, etc.

  Therefore, the average flow velocity v (m / s) of the beverage stock solution 4 is represented by the function h of the following equation.

v = h (p _L , r, μ, d, ζ) (11)
Substituting equation (11) into equation (9),
q = πr ² × h (p _L , r, μ, d, ζ) (12)
It becomes. Here, the pressure loss p _L (MPa) is expressed by the following equation.

_{p L = p G -P 0 +} p W = p G -P 0 + dg (h 1 + h 2) ... (13)
p _G : Pressure inside the stock solution container (MPa)
p _W : Pressure resulting from the remaining amount of the beverage stock solution 4 (MPa)
h ₁ : Height from the surface of the beverage stock solution 4 to the bottom of the stock solution container 21 (m)
h ₂ : Height from the bottom of the stock solution container 21 to the water outlet 25 (m)
The value of each variable is as follows. Since the pressure P _G inside the stock solution container 28 is equal to the container interior 18 as described above, p _G = P _G = 0.2 MPa. Further, the density d of the beverage stock solution 4 varies depending on the type of the beverage stock solution, but for example, d = 0.0013 kg / m ³ . From the water surface of the beverage concentrate 4 to the bottom of the stock container 21 height, i.e. the remaining amount h ₁ of beverage concentrate 4 is the maximum 0.2 m (since the volume of the stock solution vessel 21 is 4 liters) is a beverage concentrate 4 After using a part of (that is, from the stock solution outlet 25), the value becomes smaller. Although the height h ₂ from the bottom of the undiluted solution container 21 to the water outlet 25 depends on the installation location of the water outlet 25, for example, it is set to the same height as the water outlet 15, that is, h ₂ = 0.03 m. Substituting each value into equation (7)
p _L = 0.2−0.1013 + 0.0013 × 9.807 × (h ₁ +0.03) −P _s (14)
It becomes. Here, since h ₁ is 0.2 m or less, p _G −P ₀ >> d (h ₁ + h ₂ ), so the d (h ₁ + h ₂ ) term in the equation (13) can be ignored. Then, the equation (13) is changed to p _L = p _G −P ₀ = P _G −P ₀ (15)
Can be approximated. Therefore, from equation (15), the pressure loss p _L generated when the beverage stock solution 4 flows in the conduit 26 is the height h ₁ from the surface of the beverage stock solution 4 to the bottom of the stock solution container 21, that is, the beverage stock solution 4. without depending on the remaining amount, it can be seen that depends only on the pressure P _G in the vessel interior 18.

Here, when substituting equation (15) into equation (12),
q = πr ² × h (p _G , P ₀ , r, μ, d, ζ) (16)
It becomes.

  Next, the ratio Q / q of the supply amount Q of the carbonated water 3 from the water outlet 15 and the supply amount q of the beverage stock solution 4 from the stock solution outlet 25 is expressed by the following equation from the equations (5) and (10): expressed.

Q / q = πR ² × F (P _G , P ₀ , R, Μ, D, Ζ) / {πr ² × h (p _G , P ₀ , r, μ,
d, ζ)}
= R ² / r ² × F (P _G , P ₀ , R, Μ, D, Ζ) / h (p _G , P ₀ , r, μ, d, ζ) (17)
Since each variable in the equation (17) does not change during the production of the carbonated beverage 5, Q / q = constant. Therefore, the mixing ratio of the carbonated water 3 and the beverage stock solution 4 contained in the carbonated beverage 5 to be produced is always constant without depending on the remaining amount H ₁ of the carbonated water 3 and the remaining amount h ₁ of the beverage stock solution 4. I know that there is.

  From the above, the carbonated beverage production apparatus 1 of the embodiment can continuously produce the carbonated beverage 5 in which the carbonated water 3 and the beverage stock solution 4 are contained at a predetermined mixing ratio. In addition, the carbonated beverage production apparatus 1 of the embodiment has a volume of about 38 liters and a weight of about 7 kg as described above (when there are two beverage stock solution supply devices 20. However, carbon dioxide hydrate 2, carbonate Since the carbonated water 3 and the beverage stock solution 4 stored in the lower part of the container 11 of the water supply device 10 are small and relatively light in weight, it is easy to carry.

Since the inside 18 of the carbonated water supply device 10 is maintained at −20 ° C. and 2 kg / cm ² by the heat insulating material 12 and the pressure control valve 13, for example, when the outside temperature is 30 ° C., the outside 18 When the temperature is 0 ° C., the carbon dioxide hydrate 2 can be stored in the container 13 for about 8 days, and the carbonated beverage 5 can be produced during this period.

  When the decomposition rate of the carbon dioxide hydrate 2 is slow and the carbonated water supply device 10 does not store the required amount of carbonated water 3, the inside of the container 18 is heated to promote the decomposition of the carbon dioxide hydrate 2. be able to. By making the heat insulating material 12 into a panel shape and removing a part of the heat insulating material 12 to weaken the heat insulating effect, the temperature inside the container 18 may be increased, or the temperature of the electric heater 34 may be increased.

  In addition, in order to prevent the carbonated water 3 stored in the lower part of the container 11 of the carbonated water supply apparatus 10 from freezing, a heat insulating material different from the heat insulating material 12 covering the container 11 is provided in the lower part of the container 11. May be provided. It is desirable that this heat insulating material is covered with plastic and clean.

  Moreover, the carbonated beverage 5 which has a required carbonic acid density | concentration according to a use can be obtained by adjusting the pressure control valve 13 of the carbonated water supply apparatus 10 and changing the pressure of the container inside 18. FIG.

  Further, the carbonated water 3 and the beverage stock solution 4 contained in the carbonated beverage 5 to be produced are adjusted by adjusting the opening degree of the flow rate control valve 17 of the carbonated water supply device 10 and the stock solution flow rate control valve 27 of the beverage stock solution supply device 20. It is also possible to change the mixing ratio.

  The present invention is not limited to the above embodiment, and various modifications and changes can be made within the scope of the technical idea of the present invention. For example, the carbonated beverage production apparatus 1 may be provided with mechanical means or electrical means for opening and closing the cock valve 32 of the carbonated water supply device 10 and the stock solution cock valve 33 of the beverage stock solution supply device 20 simultaneously.
