Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention freezes water as ice crystals in alcoholic beverages such as sake, fruit liquor and liqueur, or beverages such as juices and aqueous solutions such as herbal extract. The present invention relates to a manufacturing method and an apparatus for manufacturing an ice crystal-containing beverage, which comprises utilizing the rotation of a container to manufacture the ice crystal-containing beverage.

(Prior Art) Conventionally, as an ice crystal-containing beverage of this kind, in the field of sake, the water of sake was frozen in order to provide consumers with the fresh aroma and taste of freshly squeezed sake. Frozen sake
The so-called "frozen sake" is usually frozen in a stationary state after filling sake into a container such as a bottle for serving to consumers.

(Problems to be Solved by the Invention) However, when sake is frozen by the above method, since ice crystals grow from the wall surface of the container toward the center of the container, needle-like or flaky ice crystals form a layer. Therefore, when "frozen liquor" is to be taken out of the container, the liquidity becomes poor, and there is a problem that it is necessary to wait until it is thawed. In addition, since the ice crystals are needle-shaped or thin pieces as described above, when served in a semi-thawed state, the texture becomes rough and the texture is not good,
In addition, even if the size of the ice crystals is made as small as 0.1 mm or less, this time the texture becomes too smooth, and the ice crystals in the mouth dissolve more quickly, so the texture is not so good. I had a problem.

Therefore, the present invention is a method for producing an ice crystal-containing beverage having good fluidity and an excellent texture, and an apparatus for producing the ice crystal-containing beverage using the rotation of a container. To do.

(Means for Solving the Problem) A method for producing an ice crystal-containing beverage using the rotation of a container according to claim 1 of the present invention is a cylindrical container in which an appropriate amount of a beverage is enclosed is about 1 to 20 ° C from the freezing point of the beverage. It is constructed by cooling while rotating around a longitudinal axis in an air atmosphere of low temperature.

Further, an apparatus for producing an ice crystal-containing beverage utilizing the rotation of the container according to claim 2 is an apparatus for carrying out the method according to claim 1, and holds a cylindrical container containing a beverage in a horizontal state. It is configured to include a holding device and a motor that rotationally drives the holding device.

(Operation) In the method for producing an ice crystal-containing beverage using the rotation of the container according to claim 1 of the present invention, since the cylindrical container containing the beverage is cooled while being rotated, the inner wall of the container is The small ice crystals formed along the surface of the inner wall fall off due to rotation,
Floats in beverage. The ice crystals formed along the inner wall thus fall off one after another and float in the beverage, and as the entire beverage rotates, the small ice crystals are bound and absorbed by the large ice crystals, and the ice crystals gradually become spherical. And become bigger.

Further, in the device according to the second aspect of the present invention, the holding device for holding the cylindrical container in the horizontal state is rotated by driving the motor, so that the beverage in the container can be given a rotational movement.

(Embodiment) Next, one embodiment of the present invention will be described with reference to the accompanying drawings, taking as an example a manufacturing method and a manufacturing apparatus for an ice crystal-containing alcoholic beverage among ice crystal-containing beverages.

First, a first embodiment of a manufacturing method and a manufacturing apparatus for an ice crystal-containing alcoholic beverage according to the first embodiment will be described with reference to FIGS. 1 and 2.

In the manufacturing apparatus shown in FIG. 1 and FIG. 2, 1 is a machine frame, and shaft portions 2a and 3a of a pair of rollers 2 and 3 are parallel to each other in a horizontal plane via bearings 4 and 4 on upper portions thereof. It is supported. A motor 5 is installed below the machine casing 1, and a pulley 6 is fixed to an output shaft 5 a of the motor 5. A pulley 7 is fixed to the end of the shaft 2a of one of the rollers 2 and 3, and a belt 8 is stretched between the pulley 6 and the pulley 7.

Reference numeral 9 denotes a cylindrical glass container, the side surfaces of which are the rollers 2, 3
Both of them are placed horizontally in contact with each other. This container 9 is a general sales container for alcoholic drinks put on the market, and the container having an inner volume of 100 ml to 10,000 ml is used.

In the above manufacturing apparatus, when the motor 5 is driven, the roller 2 is rotationally driven via the belt 8, the friction between the roller 2 and the side surface of the container 9 causes the container 9 to rotate, and further the friction between the side surface of the container 9 and the roller 3 occurs. This causes the roller 3 to follow and rotate.

Next, a method for producing ice crystals by the above-described manufacturing apparatus will be sequentially described.

First, an alcoholic beverage such as sake is put in the container 9 as shown in FIG.
% And put on the rollers 2 and 3 with the lid on.

Next, the device is placed in an air atmosphere at a temperature 1 to 20 ° C. lower than the freezing point of the alcoholic beverage, for example, in a refrigerator, and the motor 5
Is driven to rotate the container 9.

Then, small ice crystals are first formed along the inner wall of the container 9, but these ice crystals fall off from the inner wall by rotation and float in the alcoholic beverage. The ice crystals formed along the inner wall drop off one after another in this manner and float in the alcoholic beverage, and as the whole alcoholic beverage is rotated by the rollers 2 and 3, the large ice crystals become small ice crystals. As they are bound and absorbed, the ice crystals gradually become spherical and become larger.

When the rotation is continued for about 3 hours, an alcoholic beverage containing ice crystals 11 to 11 having a diameter D of about 0.05 mm to 1.0 mm, preferably about 0.1 mm to 0.5 mm is obtained as shown in FIG. . In FIG. 3, 12 is a liquid portion containing alcohol and non-iced water, and a beverage component other than these dissolved in alcohol and water, and ice crystals 11 to 11 are liquid portions 1
It is floating inside 2.

Since such ice crystals 11 to 11 have a spherical shape, the degree of freedom of movement in the liquid component is increased, and good fluidity is obtained. Therefore, when the alcoholic beverage is taken out from a container such as a bottle, the alcoholic beverage can smoothly flow out from the mouth of the container. Further, since the ice crystals 11 to 11 are spherical, the texture of the tongue becomes smooth when used for drinking. Furthermore, since the spherical shape has the smallest solid surface area in the same volume, the ice-melting rate is slow, and the shape is constant, which makes it easy to control the ice-melting rate by setting the diameter. The diameter D of 11 to 11 is 0.05 mm to 1.
By setting it to 0 mm, preferably 0.1 mm to 0.5 mm, when it is used for drinking, it does not melt too quickly in the mouth and an extremely good texture is obtained.

Here, the reason why the amount of the alcoholic beverage in the container 9 is 90% or less of the volume of the container 9 and at least 40% is 90
When it is more than%, the rotation of the alcoholic beverage in the container 9 becomes poor, and it takes time to manufacture,
In addition, when the amount is less than 40%, the production amount is reduced.

Furthermore, by cooling in an air atmosphere at a temperature lower than the freezing point of the alcoholic beverage by 1 to 20 ° C., ice crystals adhered to the wall surface of the container 9 when rapidly cooled in a refrigerant such as brine and the temperature of the container 9 It is possible to prevent contamination by the refrigerant.

Next, an apparatus according to a modification of the first embodiment will be described as a second embodiment with reference to FIG. 4 below. The first in the figure
The same members as those in the embodiment are designated by the same reference numerals and the description thereof will be omitted.

FIG. 4 is a view corresponding to FIG. 1 of the first embodiment, in which the machine frame 13 is a support frame 13a placed on a fixed surface and bearings 14 and 14 (which are attached to one end side of the support frame 13a). (Only one is shown in the drawing), and a tilting frame 13b having a support shaft 15 at a right angle to the rollers 2 and 3 rotatably supported on both sides. With this configuration, the tilting frame 13b can tilt about one end side with respect to the support frame 13a, and the tilting frame 13b has members such as the rollers 2 and 3 and the motor 5 similar to the machine frame 1 of the first embodiment. Is installed. On the other hand, a motor 16 separate from the motor 5 is attached to the other end of the support frame 13a, and a circular cam plate 17 is eccentrically attached to the output shaft 16a of the motor 16. Further, a cam receiving member 19 that abuts on the outer peripheral surface of the cam plate 17 is attached to the lower surface of a part of the frame portion 18 of the tilting frame 13b facing the cam plate 17.

Therefore, in the apparatus of the second embodiment, when the motor 16 is driven, the eccentric movement of the cam plate 17 causes the other end of the tilting frame 13b to move up and down, resulting in vertical vibration of the container 9. Therefore, the stirring power of the alcoholic beverage is strengthened, and the growth of ice crystals is further promoted.

The conditions for producing ice crystals by the apparatus of the second embodiment are the same as those of the first embodiment, and ice crystals of a desired size can be obtained in a shorter time than the apparatus of the first embodiment.

In the above embodiment, the rollers 2 and 3 were used as holding devices for holding the container 9 in a horizontal position, but instead of these, for example, a device for sandwiching the container 9 from the front and back sides was provided, and in this holding condition. It may be configured to rotate.

Further, although the above-mentioned embodiments have been described in relation to the ice crystal-containing alcoholic drink, the same method and apparatus can be used for the ice crystal-containing drink such as juice and water-soluble liquid such as herbal water extract.

(Effect) The method and apparatus for producing an ice crystal-containing beverage using the rotation of the container of the present invention uses a container such as a glass container suitable for drinking as it is, and has good fluidity and texture by a simple device. The ice crystal-containing beverage having the above has the advantage that it can be made as many as desired at a food shop or at home according to the desired amount. Further, since the cooling atmosphere is air, there is no concern that the container will be contaminated by a refrigerant such as brine, and there is an advantage that handling is easy.
