Description

本発明は、炭酸水等の気体を溶解した溶液を固化させて、炭酸氷等の気体溶解氷を製造する装置及び方法に関する。 The present invention relates to an apparatus and a method for producing gas-melted ice such as carbonated ice by solidifying a solution in which a gas such as carbonated water is dissolved.

炭酸水を氷結させて炭酸氷を得ることができれば、炭酸氷を適当な大きさに割って飲み物に入れたり、炭酸飲料に入れて炭酸の濃度を下げないようにしたり、そのまま食して新しい食感が得られることから大きな需要が期待できるが、炭酸氷の製造は困難とされている。なぜなら、炭酸水を氷結させようとすると、氷の結晶化が進むにつれて炭酸水に含まれている炭酸が大気中に放出されてしまうからである。 If carbonated water can be frozen and carbonated ice can be obtained, the carbonated ice can be divided into appropriate sizes and added to drinks, or added to carbonated drinks so as not to lower the concentration of carbonic acid, or can be eaten as it is to have a new texture. However, it is difficult to produce carbonated ice. This is because, when trying to freeze carbonated water, as the crystallization of ice proceeds, carbonic acid contained in the carbonated water is released into the atmosphere.

そこで、特許文献１では、炭酸ガス入りの製氷原水が注水される耐圧製氷容器と、加圧媒体が供給されることで膨脹し、耐圧製氷容器内に注水されている製氷原水面に接触するよう、耐圧製氷容器内に配装されている中空弾性加圧嚢と、耐圧製氷容器をその外部から冷却するブライン包覆部、同じく中心側から冷却する中央ブライン供給部からなる冷却手段とを備えたことを特徴とする炭酸入り氷の製造装置の発明が開示されている。
また、特許文献２では、製氷原水を耐圧容器に所定の位置まで注水し、前記製氷原水にアルコール類と炭酸ガスを溶解させて不溶性ガスにて加圧し、耐圧容器を冷却して前記製氷原水を凍結させることを特徴とする炭酸入り氷の製造方法の発明が開示されている。 Therefore, in Patent Document 1, a pressure-resistant ice-making container into which raw ice making water containing carbon dioxide gas is injected, and a pressurized medium are supplied so that the container expands and comes into contact with the original ice-making water surface poured into the pressure-resistant ice making container. A hollow elastic pressure sac provided in the pressure-resistant ice-making container, a brine covering portion for cooling the pressure-resistant ice-making container from the outside, and a cooling means including a central brine supply portion for cooling from the center side as well. An invention of an apparatus for producing carbonated ice, which is characterized by the above, is disclosed.
Further, in Patent Document 2, ice making raw water is poured into a pressure-resistant container to a predetermined position, alcohols and carbon dioxide are dissolved in the ice making raw water and pressurized with an insoluble gas, and the pressure-resistant container is cooled to cool the ice making raw water. An invention of a method for producing carbonated ice, which is characterized by freezing, is disclosed.

しかしながら、特許文献１及び２の発明は、耐圧（製氷）容器の上蓋を外して耐圧（製氷）容器内に製氷原水を注水し、製氷後に再び耐圧（製氷）容器の上蓋を外して耐圧（製氷）容器内の炭酸氷を取り出さなければならないため、炭酸氷を大量に自動生産することができない。 However, the inventions of Patent Documents 1 and 2 disclose the upper lid of the pressure-resistant (ice making) container, remove the upper lid of the pressure-resistant (ice making) container, pour the raw water for ice making into the pressure-resistant (ice-making) container, remove the upper lid of the pressure-resistant (ice making) container again after ice making, and remove the upper lid. ) Since the carbonated ice in the container must be removed, it is not possible to automatically produce a large amount of carbonated ice.

本発明の一実施形態に係る炭酸氷製造装置１０（本発明の「気体溶解氷製造装置」に相当）の構成を図１に示す。
炭酸氷製造装置１０は、炭酸水の製造に使用され製造後の炭酸水を貯留する炭酸水用耐圧容器１１と、炭酸水用耐圧容器１１から供給される炭酸水を貯留して氷結（固化）させる耐圧製氷容器１２と、炭酸水用耐圧容器１１内及び耐圧製氷容器１２内を真空にする真空ポンプ１５と、炭酸水用耐圧容器１１内及び耐圧製氷容器１２内に炭酸ガスを送給する炭酸ガスボンベ（炭酸ガス送給手段）１６と、設定水位まで炭酸水が注水された耐圧製氷容器１２内に不活性ガスを送給して炭酸水を加圧する不活性ガスボンベ（不活性ガス送給手段）１７（本発明の「加圧手段」に相当）とを備えている。 FIG. 1 shows the configuration of a carbonated ice producing apparatus 10 according to one embodiment of the present invention (corresponding to the “gas melting ice producing apparatus” of the present invention).
The carbonated ice producing apparatus 10 is used for producing carbonated water and stores the carbonated water after the production. The carbonated water pressure container 11 stores carbonated water supplied from the carbonated water pressure container 11 and freezes (solidifies). Pressure-resistant ice-making container 12, a vacuum pump 15 for evacuating the inside of the pressure-resistant container 11 for carbonated water and the inside of the pressure-resistant ice-making container 12, and a carbonic acid for supplying carbon dioxide gas into the pressure-resistant container 11 for carbonated water and the pressure-resistant ice making container 12. A gas cylinder (carbon dioxide gas supply means) 16 and an inert gas cylinder (inert gas supply means) for supplying an inert gas into the pressure-resistant ice-making container 12 filled with carbonated water to a set water level to pressurize the carbonated water. 17 (corresponding to the “pressurizing means” of the present invention).

真空ポンプ１５は、配管５１、５０を介して炭酸水用耐圧容器１１に接続され、配管５１、５４、５２を介して耐圧製氷容器１２に接続されている。配管５１の経路上には電動弁２３が、配管５４の経路上には電動弁２５がそれぞれ設置されている。 The vacuum pump 15 is connected to the pressure-resistant container for carbonated water 11 via pipes 51 and 50, and connected to the ice-resistant container 12 via pipes 51, 54 and 52. The motor-operated valve 23 is provided on the path of the pipe 51, and the motor-operated valve 25 is provided on the path of the pipe 54.

炭酸ガスボンベ１６から炭酸水用耐圧容器１１へは配管５２、５０を介して、炭酸ガスボンベ１６から耐圧製氷容器１２へは配管５２を介して、それぞれ炭酸ガスが送給される。配管５０の経路上には電動弁２６と逆止弁３６が、配管５２の経路上には電動弁２７と逆止弁３７がそれぞれ設置されている。 Carbon dioxide gas is supplied from the carbon dioxide gas cylinder 16 to the pressure-resistant container for carbonated water 11 via pipes 52 and 50, and from the carbon dioxide gas cylinder 16 to the pressure-resistant ice making vessel 12 via pipe 52. The motor-operated valve 26 and the check valve 36 are provided on the path of the pipe 50, and the motor-operated valve 27 and the check valve 37 are provided on the path of the pipe 52.

不活性ガスボンベ１７から耐圧製氷容器１２へは配管５３を介して不活性ガスが送給される。配管５３の経路上には電動弁２８が設置されている。
なお、不活性ガスには窒素やアルゴン等を使用することができる。 An inert gas is supplied from the inert gas cylinder 17 to the pressure-resistant ice maker 12 via a pipe 53. The motor-operated valve 28 is provided on the path of the pipe 53.
Note that nitrogen, argon, or the like can be used as the inert gas.

炭酸水用耐圧容器１１には、炭酸水用耐圧容器１１内に原料水を注水するための電動弁２１付きの配管４５と、原料水が設定水位になると作動して注水を停止させるレベル計３９が設置されている。
また、炭酸水用耐圧容器１１内の原料水を炭酸化させるため、炭酸水用耐圧容器１１には、炭酸水用耐圧容器１１内の原料水（炭酸水）を循環させる設備が設置されている。具体的には、炭酸水用耐圧容器１１内の原料水（炭酸水）を循環させる循環ポンプ１８と、循環させた原料水（炭酸水）を炭酸水用耐圧容器１１内に噴射するスプレーノズル３８と、循環ポンプ１８とスプレーノズル３８とを繋ぐ配管４６、４７及び三方弁３４が設置されている。
なお、配管４７上に別途熱交換器等の冷却手段を備えていても良い。冷却手段を備えることにより、炭酸水を循環させる間に炭酸水の温度が上がり、原料水中の二酸化炭素濃度が低下することを防止することができる。 The pressure-resistant container for carbonated water 11 has a pipe 45 with an electric valve 21 for injecting the raw water into the pressure-resistant container 11 for carbonated water, and a level meter 39 that operates when the raw water reaches a set water level and stops the water injection. Is installed.
In addition, in order to carbonate the raw water in the pressure-resistant container for carbonated water 11, equipment for circulating the raw water (carbonated water) in the pressure-resistant container for carbonated water 11 is installed in the pressure-resistant container for carbonated water 11. . Specifically, a circulation pump 18 for circulating the raw water (carbonated water) in the pressure-resistant container for carbonated water 11, and a spray nozzle 38 for injecting the circulated raw water (carbonated water) into the pressure-resistant container 11 for carbonated water And piping 46 and 47 connecting the circulation pump 18 and the spray nozzle 38 and the three-way valve 34 are provided.
Note that a separate cooling means such as a heat exchanger may be provided on the pipe 47. By providing the cooling means, it is possible to prevent the temperature of the carbonated water from rising while circulating the carbonated water, and prevent the carbon dioxide concentration in the raw water from decreasing.

炭酸水用耐圧容器１１から耐圧製氷容器１２へ炭酸水を供給する際は、三方弁３４を切り替えて循環ポンプ１８を作動させ、配管４６、４８を介して耐圧製氷容器１２に炭酸水を供給する。配管４８の経路上には電動弁２２と逆止弁３５が設置されている。
その際、炭酸水用耐圧容器１１内の圧力と耐圧製氷容器１２内の圧力を同じレベルにするため、炭酸水用耐圧容器１１と耐圧製氷容器１２は、均圧弁３３を有する配管４９により接続されている。
本実施形態で、炭酸水用耐圧容器１１内の圧力と耐圧製氷容器１２内の圧力を同じレベルにするのは、炭酸水用耐圧容器１１から耐圧製氷容器１２にスムーズに炭酸水を供給するためである。両者の間に圧力差があると、炭酸水が炭酸水用耐圧容器１１に滞留したり、あるいは炭酸水が耐圧製氷容器１２に向けて勢いよく流れてしまい、スムーズに炭酸水を供給できなくなってしまう。また、圧力は必ずしも同じレベルでなくてもよく、圧力差を低減させるように制御すれば足りる。例えば炭酸水用耐圧容器１１内の圧力を耐圧製氷容器１２内の圧力よりも少し高めにすることにより、炭酸水の供給速度を早めることができる。
また、本実施形態では、均圧手段として均圧弁３３と配管４９を用いたが、他の手段を用いても良い。例えば炭酸水用耐圧容器１１と耐圧製氷容器１２のそれぞれにコンプレッサや開放弁などの圧力調整装置を接続し、これらが連動して両者の圧力差を低減するように制御しても良い。 When supplying carbonated water from the carbonated water pressure-resistant container 11 to the pressure-resistant ice making container 12, the three-way valve 34 is switched to operate the circulation pump 18, and the carbonated water is supplied to the pressure-resistant ice making container 12 through the pipes 46 and 48. . The motor-operated valve 22 and the check valve 35 are installed on the path of the pipe 48.
At this time, in order to make the pressure in the pressure-resistant container for carbonated water 11 and the pressure in the pressure-resistant ice making container 12 the same level, the pressure-resistant container for carbonated water 11 and the pressure-resistant ice making container 12 are connected by a pipe 49 having a pressure equalizing valve 33. ing.
In the present embodiment, the pressure in the pressure-resistant container 11 for carbonated water and the pressure in the pressure-resistant ice making container 12 are set to the same level in order to smoothly supply carbonated water from the pressure-resistant container 11 for carbonated water to the pressure-resistant ice container 12. It is. If there is a pressure difference between the two, the carbonated water stays in the pressure-resistant container 11 for carbonated water, or the carbonated water flows vigorously toward the pressure-resistant ice-making container 12, so that the carbonated water cannot be supplied smoothly. I will. Further, the pressures do not necessarily have to be at the same level, and it is sufficient to perform control so as to reduce the pressure difference. For example, by setting the pressure in the pressure-resistant container 11 for carbonated water slightly higher than the pressure in the pressure-resistant ice making container 12, the supply speed of the carbonated water can be increased.
Further, in this embodiment, the equalizing valve 33 and the pipe 49 are used as the equalizing means, but other means may be used. For example, a pressure adjusting device such as a compressor or an opening valve may be connected to each of the pressure-resistant container for carbonated water 11 and the pressure-resistant ice making container 12, and these may be linked to control such that the pressure difference between them is reduced.

耐圧製氷容器１２は竪型円筒状とされ、下面に設けられた炭酸氷排出口（図示省略）（本発明の「排出口」に相当）には炭酸氷排出口と同じ若しくはそれを超える口径を有する電動ボール弁１４が接続されている（図２参照）。
電動ボール弁１４は、炭酸氷排出口に接続される管体１４ａと、管体１４ａ内に嵌め込まれたボール１４ｃを回動軸１４ｄを介して回動させるアクチュエータ１４ｂとから構成されている（図３（Ａ）〜（Ｃ）参照）。ボール１４ｃの中央部には、炭酸氷排出口と同じ若しくはそれを超える口径を有する貫通孔が形成されており、回動軸１４ｄを±９０°回動させることにより電動ボール弁１４が開閉する。
本実施形態では、炭酸氷排出口は、耐圧製氷容器１２の下面に設けられているので、炭酸氷を自然落下させることにより取り出すことができ、一連の作業の自動化に資するものである。もっとも、耐圧製氷容器１２を横置きにする場合は、炭酸氷排出口は耐圧製氷容器１２の横面に設けてもよい。 The pressure-resistant ice making container 12 has a vertical cylindrical shape, and a carbonated ice discharge port (not shown) provided on the lower surface (corresponding to the “discharge port” of the present invention) has a diameter equal to or larger than the carbonated ice discharge port. The electrically operated ball valve 14 is connected (see FIG. 2).
The electric ball valve 14 includes a tube 14a connected to the carbonated ice discharge port, and an actuator 14b for rotating a ball 14c fitted in the tube 14a via a rotation shaft 14d (FIG. 3 (A) to (C)). A through hole having a diameter equal to or larger than the carbonated ice discharge port is formed in the center of the ball 14c, and the electric ball valve 14 opens and closes by rotating the rotating shaft 14d by ± 90 °.
In the present embodiment, since the carbonated ice discharge port is provided on the lower surface of the pressure-resistant ice making container 12, the carbonated ice can be taken out by allowing it to fall naturally, which contributes to automation of a series of operations. However, when the pressure-resistant ice maker 12 is placed horizontally, the carbonated ice discharge port may be provided on the lateral surface of the pressure-resistant ice maker 12.

一方、耐圧製氷容器１２の上面はフランジ１２ａで封止され、フランジ１２ａを貫通する配管５２、５３、５５を介して、炭酸ガスボンベ（炭酸ガス送給手段）１６、不活性ガスボンベ（不活性ガス送給手段）１７、排気用の電動弁２４（本発明の「開放弁」に相当）及び圧力センサー４０にそれぞれ接続されている。
排気用の電動弁２４は、耐圧製氷容器１２内の圧力を低減させるために設けられており、炭酸氷排出口が設けられている面以外の面、ここでは対向する面に設けられている。炭酸氷排出口が設けられている面以外の面に設けることにより、炭酸氷排出口と電動弁２４とが干渉することなく、また電動弁２４側の圧力が炭酸水排出口側の圧力に差を設けるようにすることにより、スムーズに炭酸氷を炭酸氷排出口から排出することが可能となる。 On the other hand, the upper surface of the pressure-resistant ice-making container 12 is sealed with a flange 12a, and a carbon dioxide gas cylinder (carbon dioxide gas supply means) 16 and an inert gas cylinder (inert gas gas supply) are provided through pipes 52, 53, and 55 passing through the flange 12a. (Opening valve) of the present invention, and a pressure sensor 40.

次に、上記構成を有する炭酸氷製造装置１０を用いた炭酸氷の製造方法（本発明の「気体溶解氷製造方法」に相当）について説明する。
炭酸氷の製造方法は、大きく分けて、炭酸水の製造、炭酸水の耐圧製氷容器への注入、炭酸氷の製造の３つのプロセスから構成される。以下、順に説明する。 Next, a method for producing carbonated ice using the carbonated ice producing apparatus 10 having the above configuration (corresponding to the “method for producing gas-melted ice” of the present invention) will be described.
The method for producing carbonated ice is roughly divided into three processes: production of carbonated water, injection of carbonated water into a pressure-resistant ice-making container, and production of carbonated ice. Hereinafter, description will be made in order.

［炭酸水の製造］
（１）電動弁２３を開けて真空ポンプ１５を作動させ、炭酸水用耐圧容器１１内を真空にする。
このステップは必須ではないが、真空にすることにより原料水に含まれる不純物を気化させて取り除くことができる。
（２）真空引きが完了した時点で電動弁２３を閉じ、真空ポンプ１５を停止する。 [Production of carbonated water]
(1) The electric valve 23 is opened and the vacuum pump 15 is operated to evacuate the inside of the pressure-resistant container 11 for carbonated water.
Although this step is not essential, impurities contained in the raw water can be vaporized and removed by applying a vacuum.
(2) When the evacuation is completed, the electric valve 23 is closed and the vacuum pump 15 is stopped.

（３）電動弁２１を開き、原料水を炭酸水用耐圧容器１１に注入する。炭酸の溶解度を上げるため、原料水は、できるだけ０℃近い低温水が良い。
（４）原料水が設定水位になるとレベル計３９が作動し、電動弁２１が閉じる。 (3) Open the electric valve 21 and inject the raw water into the pressure-resistant container 11 for carbonated water. In order to increase the solubility of carbonic acid, the raw water is preferably low-temperature water as close to 0 ° C. as possible.
(4) When the raw water reaches the set water level, the level gauge 39 operates, and the electric valve 21 closes.

（５）電動弁２６を開き、炭酸ガスボンベ１６から炭酸水用耐圧容器１１へ炭酸ガスを送給する。注入圧力は、炭酸氷の炭酸濃度を予め想定し適宜決定する。概ね０．１５ＭＰａ〜１．０ＭＰａ程度である。
上記（１）のステップで炭酸水用耐圧容器１１内を真空にしない場合は、炭酸ガスを供給することにより空気より比重の大きい炭酸ガスが炭酸水用耐圧容器１１の底からたまるので、別途設ける開放弁等から空気を追い出すことにより、炭酸ガスを炭酸水用耐圧容１１内に満たすことができる。
（６）炭酸ガスの送給が完了した時点で電動弁２６を閉じる。 (5) Open the motor-operated valve 26 and feed the carbon dioxide gas from the carbon dioxide gas cylinder 16 to the pressure-resistant container for carbonated water 11. The injection pressure is appropriately determined by assuming the carbonic acid concentration of the carbonated ice in advance. It is about 0.15 MPa to about 1.0 MPa.
If the inside of the pressure-resistant container for carbonated water 11 is not evacuated in the step (1), the carbon dioxide gas having a specific gravity higher than that of air is accumulated from the bottom of the pressure-resistant container for carbonated water 11 by supplying carbon dioxide gas. By expelling the air from an opening valve or the like, the carbon dioxide gas can be filled in the carbonated water pressure-resistant capacity 11.
(6) When the supply of the carbon dioxide gas is completed, the electric valve 26 is closed.

（７）三方弁３４のＢ弁を閉じてＡ弁を開き、循環ポンプ１８を作動させる。これにより、スプレーノズル３８から炭酸水用耐圧容器１１内に原料水（炭酸水）が噴射され、炭酸水用耐圧容器１１内の原料水（炭酸水）が循環混合される。水量にもよるが３分〜３０分程度で炭酸水は最大濃度に達する。
このような循環ポンプとスプレーを使う以外の方法として、例えば撹拌、あるいは螺旋状のプレートに原料水を落下させるなどの方法がある。つまり、炭酸ガスと原料水との接触面積を増大させる方法であれば、任意の方法を用いることができる。
（８）原料水の炭酸化作業が完了した時点で循環ポンプ１８を停止する。 (7) The B valve of the three-way valve 34 is closed, the A valve is opened, and the circulation pump 18 is operated. Thereby, the raw water (carbonated water) is injected from the spray nozzle 38 into the pressure-resistant container for carbonated water 11, and the water (carbonated water) in the pressure-resistant container 11 for carbonated water is circulated and mixed. The carbonated water reaches the maximum concentration in about 3 to 30 minutes, depending on the amount of water.
As a method other than using such a circulating pump and a spray, there is a method of, for example, stirring or dropping raw water on a spiral plate. That is, any method can be used as long as the contact area between the carbon dioxide gas and the raw water is increased.
(8) When the carbonation of the raw water is completed, the circulation pump 18 is stopped.

［炭酸水の耐圧製氷容器への注入］
（１）電動弁２５を開け、電動ボール弁１４を閉じて真空ポンプ１５を作動させ、耐圧製氷容器１２内を真空にする。
このステップも必須ではないが、真空にすることにより次のステップで炭酸ガスを効率よく供給することが可能となる。
（２）真空引きが完了した時点で電動弁２５を閉じ、真空ポンプ１５を停止する。 [Injection of carbonated water into pressure-resistant ice maker]
(1) The electric valve 25 is opened, the electric ball valve 14 is closed, the vacuum pump 15 is operated, and the inside of the pressure-resistant ice making container 12 is evacuated.
Although this step is not essential, the vacuum can make it possible to supply carbon dioxide gas efficiently in the next step.
(2) When the evacuation is completed, the electric valve 25 is closed and the vacuum pump 15 is stopped.

（３）電動弁２７を開き、炭酸ガスボンベ１６から耐圧製氷容器１２へ炭酸ガスを送給する。注入圧力は、前述したように、概ね０．１５ＭＰａ〜１．０ＭＰａ程度である。
上記（１）のステップで耐圧製氷容器１２内を真空にしない場合は、炭酸ガスを供給することにより空気より比重の大きい炭酸ガスが耐圧製氷容器１２の底からたまるので、電動弁２４を開いて空気を追い出すことにより、炭酸ガスを耐圧製氷容器１２内に満たすことができる。
（４）炭酸ガスの送給が完了した時点で電動弁２７を閉じる。 (3) The electric valve 27 is opened, and the carbon dioxide gas is fed from the carbon dioxide gas cylinder 16 to the pressure-resistant ice making container 12. As described above, the injection pressure is generally about 0.15 MPa to 1.0 MPa.
When the inside of the pressure-resistant ice making container 12 is not evacuated in the step (1), the electric valve 24 is opened by supplying the carbon dioxide gas, since the carbon dioxide gas having a higher specific gravity than the air accumulates from the bottom of the pressure-resistant ice making container 12. By expelling the air, carbon dioxide gas can be filled in the pressure-resistant ice making container 12.
(4) When the supply of the carbon dioxide gas is completed, the electric valve 27 is closed.

（５）電動弁２２と均圧弁３３を開くと共に、三方弁３４のＡ弁を閉じてＢ弁を開いて循環ポンプ１８を作動させ、炭酸水用耐圧容器１１から炭酸ガス雰囲気の耐圧製氷容器１２へ炭酸水を供給する。その際、炭酸水の凍結膨張による容器破壊を防止するため、炭酸水の体積の少なくとも２割以上の空間を耐圧製氷容器１２の上方に設ける。
なお、本実施形態では均圧弁３３を開いた後に炭酸水の供給を開始しているが、両者のタイミングを同時としても良い。あるいは、炭酸水の供給の開始後に均圧弁３３を開いても良い。
（６）炭酸水用耐圧容器１１から耐圧製氷容器１２への炭酸水の供給が完了（設定水位まで注水）した時点で循環ポンプ１８を停止し、電動弁２２と均圧弁３３を閉じる。 (5) The electric valve 22 and the equalizing valve 33 are opened, the three-way valve A is closed, the B valve is opened, and the circulating pump 18 is operated. Supply carbonated water to At this time, in order to prevent the destruction of the container due to the freezing and expansion of the carbonated water, a space of at least 20% of the volume of the carbonated water is provided above the pressure-resistant ice making container 12.
In the present embodiment, the supply of the carbonated water is started after the equalizing valve 33 is opened, but the timing of both may be the same. Alternatively, the equalizing valve 33 may be opened after the supply of the carbonated water is started.
(6) When the supply of carbonated water from the pressure-resistant container for carbonated water 11 to the pressure-resistant ice-making container 12 is completed (water is injected to the set water level), the circulating pump 18 is stopped, and the electric valve 22 and the equalizing valve 33 are closed.

［炭酸氷の製造］
（１）電動弁２８を開き、不活性ガスボンベ１７から耐圧製氷容器１２へ不活性ガスを送給して耐圧製氷容器１２内の炭酸水を加圧する。注入圧力は、炭酸ガス注入圧力より高く、概ね０．５ＭＰａ〜１．５ＭＰａ程度である。
このように炭酸水を加圧することにより、原料水から炭酸ガスが抜けにくくなり、炭酸氷の炭酸ガス濃度を保つことができる。
なお、供給するガスは不活性ガスには限らない。例えば、コンプレッサを用いて空気で加圧しても良い。あるいは、炭酸ガスボンベ１６を用いて炭酸ガスで加圧しても良い。炭酸ガスボンベ１６を用いる場合、圧力が不足するときはコンプレッサを併用しても良い。（２）不活性ガスの送給が完了した時点で電動弁２８を閉じる。 [Production of carbonated ice]
(1) The electric valve 28 is opened, and an inert gas is fed from the inert gas cylinder 17 to the pressure-resistant ice making container 12 to pressurize the carbonated water in the pressure-resistant ice making container 12. The injection pressure is higher than the carbon dioxide gas injection pressure, and is approximately 0.5 MPa to 1.5 MPa.
By pressurizing the carbonated water in this way, it becomes difficult for carbon dioxide gas to escape from the raw water, and the carbon dioxide concentration of the carbonated ice can be maintained.
The supplied gas is not limited to the inert gas. For example, you may pressurize with air using a compressor. Alternatively, carbon dioxide gas may be pressurized using a carbon dioxide gas cylinder 16. When the carbon dioxide gas cylinder 16 is used, a compressor may be used together when the pressure is insufficient. (2) When the supply of the inert gas is completed, the electric valve 28 is closed.

（３）電動弁３１と電動弁３０を開き、循環ポンプ１９を作動させ、冷却用ブラインタンク４３からの冷却用ブラインにより耐圧製氷容器１２（炭酸水）を冷却して炭酸氷の製造（以下、「製氷」と記す。）を開始する。冷却用ブラインの温度は概ね−１０℃〜−４０℃程度である。
（４）製氷が完了した時点で、電動弁３１と電動弁３０を閉じ、循環ポンプ１９を停止する。 (3) The electric valve 31 and the electric valve 30 are opened, the circulation pump 19 is operated, and the pressure-resistant ice making container 12 (carbonated water) is cooled by the cooling brine from the cooling brine tank 43 to produce carbonated ice (hereinafter, referred to as “carbonated ice”). Starts ice making.) The temperature of the cooling brine is generally about -10C to -40C.
(4) When the ice making is completed, the electric valves 31 and 30 are closed, and the circulation pump 19 is stopped.

（５）電動ボール弁１４と電動弁２４を開く。これにより、耐圧製氷容器１２内の圧力を低減させ、炭酸氷が耐圧製氷容器から炭酸氷排出口から勢いよく排出されて炭酸氷が砕けるのを防止することができる。
（６）電動弁３２と電動弁２９を開き、循環ポンプ２０を作動させ、加温用ブラインタンク４４からの加温用ブラインにより耐圧製氷容器１２（炭酸氷）を加温して炭酸氷を耐圧製氷容器１２の内面から剥離（以下、「脱氷」と記す。）を開始する。加温用ブラインの温度は概ね１０℃〜４０℃程度である。耐圧製氷容器１２の内面から炭酸氷が剥離すると、炭酸氷は自重により炭酸氷排出口を介して電動ボール弁１４から外部に排出される。
（７）脱氷が完了した時点で、電動弁３２と電動弁２９を閉じ、循環ポンプ２０を停止する。 (5) The electric ball valve 14 and the electric valve 24 are opened. Thereby, the pressure in the pressure-resistant ice making container 12 can be reduced, and it is possible to prevent the carbonated ice from being vigorously discharged from the pressure-resistant ice making container from the carbonated ice discharge port to break the carbonated ice.
(6) The electric valve 32 and the electric valve 29 are opened, the circulation pump 20 is operated, and the pressure-resistant ice making container 12 (carbonic ice) is heated by the heating brine from the heating brine tank 44 to withstand the carbonated ice. Peeling from the inner surface of the ice making container 12 (hereinafter, referred to as “de-icing”) is started. The temperature of the heating brine is generally about 10C to 40C. When the carbonated ice comes off from the inner surface of the pressure-resistant ice making container 12, the carbonated ice is discharged from the electric ball valve 14 to the outside through the carbonated ice discharge port by its own weight.
(7) When the deicing is completed, the electric valves 32 and 29 are closed, and the circulation pump 20 is stopped.
