Hereinafter, an embodiment of the beverage manufacturing apparatus of the present invention will be described with reference to the drawings. FIG. 1 illustrates a schematic device configuration of a beverage manufacturing apparatus 1 according to the present embodiment, mainly a bottle 2 capable of accommodating a beverage to be produced and a depressurization capable of depressurizing the inside of the bottle 2. The machine 3 is connected to the machine 3 by a pipe 4 made of a tube or the like.

The decompressor 3 includes at least a vacuum pump 31, an electromagnetic valve 32, a pressure sensor 33, a control unit 34, and a power supply unit 35, and the vacuum pump and the electromagnetic valve are based on the detection result of the pressure sensor 33. The depressurization control in the bottle 2 is possible by the control program of the control unit 34 capable of controlling the pressure. The bottle 2 is a container that does not deform under reduced pressure, and for example, transparent resin, glass, pottery, metal, or the like can be appropriately selected as the material of the container. In addition, the bottle 2 is configured to be hermetically sealed, with a lid 21 that can be opened and closed at the top of the bottle and a lower lid 22 that can be opened and closed at the bottom of the bottle. Further, the lid 21 is provided with a connection portion (not shown) that communicates with the inside of the bottle 2 and allows the pipe 4 to be attached / detached.

Further, the decompressor 3 is provided with an operation setting means including a display means (not shown), an operation button, and the like, and executes the decompression cycle described later once or a plurality of times based on the setting operation for the operation setting means. It is configured as follows.

(Beverage manufacturing method)
Next, a method for producing watered tea by the beverage producing apparatus 1 of the present embodiment will be described. First, the lower lid 22 of the bottle 2 is closed, the lid 21 is opened, a predetermined amount of water, ice, and tea leaves 10 are put into the bottle 2, and the lid 21 is closed. Then, the pipe 4 extending from the solenoid valve 32 of the pressure reducing machine 3 is connected to the connection portion of the lid 21. Subsequently, after the power of the decompressor 3 is turned on, the number of executions of the decompression cycle (see FIG. 3) described later is set by the operation setting means (not shown), and the predetermined operation set by pressing the operation start button (not shown). A number of decompression cycles are performed.

After the depressurization cycle is executed a predetermined number of times, the pipe 4 is removed from the connection portion of the lid 21. By such a series of operations, cold-brewed tea in which the components of the tea leaves 10 are extracted in the bottle 2 is produced. The bitterness component of tea, "catechins," is easily extracted at high temperatures, and the umami component, "theanine," is extracted in all temperature ranges. Due to these properties, as described above, by putting a predetermined amount of ice into the bottle 2, the water temperature is lowered to suppress the extraction of "catechins" which are bitterness components, and "theanine" which is an umami component. Can be efficiently extracted.

Next, the above-mentioned decompression cycle will be described in detail with reference to FIGS. 2 and 3. In the stage before the execution of the depressurization cycle, as shown in FIGS. 2 (A) and 3 (A), a predetermined amount of water, ice, and tea leaves 10 are charged into the bottle 2, and the inside of the bottle 2 is filled with water, ice, and tea leaves 10. The atmospheric pressure is normal pressure (1 atm). After that, the execution of the decompression cycle is started with the start of the operation of the decompressor 3. In general, water becomes heaviest when the water temperature is 4 ° C., stays below the bottle 2, and water having a water temperature lower than 4 ° C. stays above because it is light. Therefore, the water temperature in the bottle 2 is 4 ° C. or lower.

As shown in FIGS. 2B and 3B, the inside of the bottle 2 is gradually depressurized to about 0.2 atm. As a result, the tea leaves 10 swell, and water can be effectively taken into the cells of the swelled tea leaves 10. In order to sufficiently take up water into the cells, the reduced pressure state is maintained for a predetermined time, for 1 minute as the reduced pressure holding time in this embodiment.

After maintaining the depressurized state for a predetermined time, as shown in FIGS. 2 (C) and 3 (C), the depressurized state is released by the control of the decompressor 3, and the bottle 2 is opened to the atmosphere. Return the atmospheric pressure to normal pressure. Then, the normal pressure state is maintained for a predetermined time, in the present embodiment, for 30 seconds as the normal pressure holding time. As a result, the swollen tea leaves 10 are restored to their original state, and various components contained in the tea leaves 10 are extracted together with the water taken into the cells at the time of depressurization. After a predetermined number of depressurization cycles have been performed, the tea leaves 10 in the bottle 2 are pressed and the cold-brewed tea is removed from the bottle 2 as shown in FIG. 2 (D).

When the cold-brewed tea is taken out from the bottle 2, the tea leaves 10 and a small amount of liquid remain at the bottom of the bottle 2, and in particular, the liquid contained in the tea leaves 10 contains a large amount of theanine, which is an umami component. By taking out the liquid contained in the tea leaves 10 while pressing the remaining tea leaves 10, the liquid having a strong umami taste can be taken out at the end. The remaining tea leaves 10 are discarded by opening the lower lid 22 as shown in FIG. 2 (E). In the present embodiment, since the lower lid 22 that can be opened and closed is provided at the lower part of the bottle, the remaining tea leaves 10 can be easily discarded.

FIG. 3 shows a time chart of the decompression cycle in the present embodiment. As described above, in the decompression cycle, the pressure in the bottle 2 is reduced to a predetermined pressure under the control of the control unit 34. A step, a decompression holding step of holding a predetermined atmospheric pressure for a predetermined time, an opening step of opening a predetermined atmospheric pressure to the atmosphere to a normal pressure, and a normal pressure holding step of holding a normal pressure state for a predetermined time after the opening step. It is configured as follows.

(Results of component analysis of beverages)
FIG. 4 shows the component analysis results of the water-drained tea produced by the beverage manufacturing apparatus 1 of the present embodiment. That is, the tea taken out by hot water brewing (70 ° C.) for about 2 minutes, which is normally performed, the cold-brewed tea taken out by immersing the tea leaves 10 in water for about 4 hours, and the beverage manufacturing apparatus 1 of the present embodiment 2 to 8 This is a comparison of the tea taken out by performing one decompression cycle for each extracted component. As described in the table, it takes about 3 minutes for 2 cycles, about 5 minutes for 3 cycles, about 8 minutes for 5 cycles, and about 13 minutes for 8 cycles. , It is the total time required to make watered tea by vacuum extraction.

"Theanine" shown in the table of FIG. 4 is a kind of amino acid and is a source of umami. In particular, it is abundantly contained in the tea leaves 10, and the higher the tea leaves, the more theanine is contained. In addition, catechins such as "epigallocatechin", "epigallocatechin", "epigallocatechin gallate", and "epigallocatechin gallate" in the table are a kind of polyphenols and are bitterness components.

FIG. 5 shows a component comparison result between the cold-brewed tea taken out by the conventional manufacturing method and the cold-brewed tea taken out by executing eight decompression cycles (8 cycles) by the beverage manufacturing apparatus 1 of the present embodiment. ing. As shown in FIG. 5A, the beverage manufacturing apparatus 1 of the present embodiment can extract theanine equivalent to that of water-drained tea manufactured by the conventional manufacturing method over 4 hours in a short time of about 13 minutes. can.

On the other hand, as shown in FIG. 5B, the catechins, which are bitter taste components, are reduced to about half of the cold-brewed tea produced by the conventional method by producing cold-brewed tea using the beverage manufacturing apparatus 1 of the present embodiment. Extraction can be suppressed.

Further, as shown in FIG. 6, as the number of executions of the depressurization cycle increases, more catechins tend to be extracted. It can be seen that the extraction of catechins, which are bitter taste components, can be significantly suppressed. Further, among catechins, "epigallocatechin gallate", which is an ester-type catechin, is a component having a particularly strong bitterness and astringency, but the beverage manufacturing apparatus 1 of the present embodiment can suppress this most significantly. It will be possible.

FIG. 7 shows the evaluation results by a known taste sensor. From each evaluation index of "astringency stimulus" and "astringency", by using the beverage manufacturing apparatus 1 of the present embodiment, the astringency stimulus and astringency are suppressed as compared with the water-drained tea by the conventional manufacturing method. I understand. Further, looking at the evaluation index of "umami richness", the watered tea taken out by the beverage manufacturing apparatus 1 of the present embodiment shows a very high value.

From the above-mentioned analysis results and the like, it can be confirmed that according to the beverage manufacturing apparatus 1 of the present embodiment, cold brew tea having a delicious taste and richness can be produced in a very short time while suppressing astringency and bitterness.

(Other embodiments)
Although the embodiment of the beverage manufacturing apparatus of the present invention has been described above, the present invention is not necessarily limited to the above-described configuration, and various modifications such as the following are possible.

For example, the above-mentioned 1-minute decompression holding time and 30-second normal pressure holding time can be arbitrarily set, and an appropriate time can be set according to the state, quality, and type of the tea leaves 10. It is possible. Specifically, it is configured so that the optimum decompression holding time and normal pressure holding time can be investigated for each state, quality, and type of tea leaves 10, and the decompression holding time and normal pressure holding time can be set by operating the operation setting means. can do. As another method, a tea leaf selection means (not shown) is provided in the control unit 34, and the tea leaf selection means is operated to input the type of the tea leaf 10 or the like, so that the reduced pressure holding time suitable for the type of the tea leaf 10 or the normal temperature and pressure can be obtained. It can be configured to set and control the pressure holding time.

In the above-described embodiment, the pressure in the depressurized state is set to about 0.2 atm, but as a result of the demonstration experiment, by setting the pressure to 0.2 atm or less, theanine can be obtained in a short time while suppressing the extraction amount of catechins. It has been confirmed that a large amount of cold-brewed tea is produced. However, the most suitable pressure for extraction differs depending on the state, quality, and type of tea leaves 10, so a test run is performed for each type of tea leaves 10 in advance to obtain the optimum pressure according to the types of tea leaves 10. Is more preferable.

Further, in the above-described embodiment, the number of times the decompression cycle is executed is set by the operation setting means, but the operation setting is not necessarily limited to such an embodiment, and the state, quality, and type of the tea leaf 10 are set. It may be configured so that the number of executions of the decompression cycle suitable for the type of tea leaves 10 and the like may be set by the control program. With such a configuration, anyone can easily make delicious cold-brewed tea regardless of the tea leaves 10.

Further, the content of theanine and the optimum water temperature at which theanine is efficiently extracted differ depending on the type of tea leaves 10. Therefore, the number of executions of the depressurization cycle, the water temperature at the time of extraction, the decompression holding time in each cycle, the normal pressure holding time, etc. are set based on the investigation results after investigating the optimum extraction conditions for each type of tea leaves 10. Is preferable. For example, the control information of the beverage manufacturing apparatus corresponding to the type of the tea leaves 10 is stored in the storage means (not shown) of the control unit 34, and the tea leaf type is selected and set in the tea leaf selection means of the control unit 34 for selection. It is possible to make cold-brewed tea under the optimum extraction conditions for the tea leaves 10. With such a configuration, it is possible to extract the original taste of tea leaves to the maximum extent.

It is also possible to attach an ultrasonic wave generating means to the bottle 2 and apply ultrasonic waves to the bottle 2 to promote the extraction of tea leaf components. Specifically, an ultrasonic vibrator can be brought into contact with the bottle 2 and a destructive shock wave of fine bubbles called cavitation can be applied to the tea leaves 10. This makes it possible to produce cold-brewed tea containing a large amount of theanine in a shorter time while suppressing the amount of catechins extracted.

By applying ultrasonic waves to the bottle 2, there is a concern that the temperature of the liquid will rise due to ultrasonic vibration. FIG. 8 shows the results of investigating the temperature change of water due to ultrasonic vibration by applying ultrasonic waves to 200 cc of water, but the water temperature rises by 0.78 ° C per minute due to the influence of ultrasonic vibration. However, it can be seen that the water temperature rises by 14 ° C by applying ultrasonic vibration for about 18 minutes. However, as described above, the beverage manufacturing apparatus of the present invention puts a predetermined amount of ice into the bottle 2, so that it is possible to suppress an increase in water temperature due to ultrasonic vibration, and the amount of catechins extracted can be increased. It can be suppressed.

Further, as described above, catechins which are bitter taste components are easily extracted at a high temperature, and particularly when ultrasonic waves are applied to the bottle 2, a large amount of catechins may be extracted. In order to deal with such a situation, it is possible to provide the bottle 2 with a cooling device such as a Pelche type or a compressor type and a temperature measuring means, and maintain the water temperature in the bottle 2 in a low temperature state (for example, 4 ° C or less). Is. This makes it possible to efficiently extract a larger amount of theanine, which is an umami component, while suppressing the extraction of catechins, which are a bitter taste component.

Further, as another embodiment, the bottle 2 can have a double structure as shown in FIG. More specifically, in the above-described embodiment, after the cold-brewed tea is taken out from the bottle 2, in order to produce the next cold-brewed tea, the tea leaves 10 remaining in the bottle 2 are discarded, and the tea leaves are further bottled. It is necessary to wash the inside of 2 and add water, ice and tea leaves 10 again. Therefore, as shown in FIG. 9A, the bottle 2 has a double structure consisting of an outer container 23 and an inner container 24, and as shown in FIG. 9B, the outer container 23 to the inner container 24 are formed. It is configured so that it can be taken out, the cold-brewed tea after extraction can be taken out, and the remaining tea leaves 10 can be discarded.

Therefore, when producing the next cold-brewed tea, another inner container 24 containing water, ice, and tea leaves 10 prepared in advance is replaced with the outer container 23, and the production of the next cold-brewed tea is immediately started. It becomes possible to do. With such a configuration, it is possible to significantly reduce the time loss such as taking out the cold-brewed tea, discarding the remaining tea leaves, cleaning the bottle 2, etc., and by replacing the inner container 24, it can be continued in a short time. It becomes possible to produce cold-brewed tea.

In another embodiment shown in FIG. 9A, a sealing packing 211 is provided between the lid 21 and the outer container 23, but the present invention is not necessarily limited to such an embodiment. For example, a sealing packing may be provided between the lid 21 and the inner container 24, or packing may be provided on both of them.

Although one embodiment of the beverage manufacturing apparatus of the present invention has been described above with reference to the drawings and the like, the specific configuration is not limited to these embodiments. The scope of the present invention is shown by the scope of claims rather than the description of the embodiment described above, and further includes all modifications within the meaning and scope equivalent to the scope of claims. Further, the specific materials, dimensions, shapes, etc. described in the above embodiments can be changed within the range of solving the problems of the present invention.
