Description

気体溶解氷製造装置及び製造方法Gas melting ice manufacturing apparatus and manufacturing method
　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 method for producing a gas-dissolved 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 to obtain carbonated ice, carbonated ice can be divided into a suitable size and put in a drink, put in a carbonated drink so as not to lower the concentration of carbonated, eat as it is and have a new texture It can be expected that a large demand can be expected from obtaining carbon dioxide, but it is considered difficult to produce carbonated ice. This is because, when it is attempted to freeze carbonated water, carbonic acid contained in carbonated water is released to the atmosphere as crystallization of ice progresses.
　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 container into which raw carbon dioxide-containing ice-making water is injected, and a pressurized medium are supplied to expand so as to contact the ice-raw water surface injected into the pressure-resistant ice container. A hollow elastic pressurized capsule disposed in the pressure-resistant ice container, a brine covering portion for cooling the pressure-resistant ice container from the outside, and a cooling means comprising a central brine supply portion for cooling from the center side as well The invention of an apparatus for producing carbonated ice is disclosed.
Further, in Patent Document 2, raw ice-making water is poured into a pressure-resistant vessel to a predetermined position, alcohol and carbon dioxide gas are dissolved in the raw ice-making water, pressurized with insoluble gas, and the pressure-proof vessel is cooled to make the raw ice-making water The invention of a method of producing carbonated ice 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, according to the inventions of Patent Documents 1 and 2, the upper lid of the pressure resistant (ice making) container is removed and ice raw water is injected into the pressure resistant (ice making) container. After ice making, the upper lid of the pressure resistant (ice making) container is removed again to 2.) Carbonated ice can not be produced automatically in large quantities because the carbonated ice in the container must be removed.
　本発明はかかる事情に鑑みてなされたもので、気体溶解氷の製造を自動化して大量生産することが可能な気体溶解氷製造装置及び製造方法を提供することを目的とする。 The present invention has been made in view of such circumstances, and it is an object of the present invention to provide an apparatus and method for producing gas-melted ice capable of mass-producing gas-melted ice automatically.

　本発明の一実施例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。 The configuration of a carbonated ice producing apparatus 10 (corresponding to the "gas melted ice producing apparatus" of the present invention) according to an embodiment of the present invention is shown in FIG.
The carbonated ice manufacturing apparatus 10 stores the carbonated water supplied from the carbonated water pressure-resistant container 11 used for manufacturing carbonated water and stores the carbonated water after manufacture, and freezes (solidifies) the carbonated water supplied from the carbonated water pressure-resistant container 11 The pressure-resistant ice making container 12 to be made, the vacuum pump 15 making the inside of the pressure-resistant ice forming container 12 and the pressure forming ice-forming container 12 vacuum, the carbonated water supplying the carbon dioxide gas into the pressure forming container 12 for carbonated water An inert gas cylinder (inert gas supply means) for supplying an inert gas to pressurize the carbonated water into a gas cylinder (carbon dioxide gas supply means) 16 and a pressure-resistant ice making container 12 with carbonated water injected to a set water level. And 17 (corresponding to the "pressure unit" 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 11 for carbonated water through the pipes 51 and 50, and is connected to the pressure-resistant ice-making container 12 through the pipes 51, 54 and 52. The motor-operated valve 23 is installed on the path of the pipe 51, and the motor-operated valve 25 is installed 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 11 for carbonated water via the pipes 52 and 50, and from the carbon dioxide gas cylinder 16 to the pressure-resistant ice making container 12 via the pipe 52. The motor-operated valve 26 and the check valve 36 are installed on the path of the pipe 50, and the motor-operated valve 27 and the check valve 37 are installed 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 fed from the inert gas cylinder 17 to the pressure-resistant ice making container 12 through a pipe 53. An electrically operated valve 28 is installed on the path of the pipe 53.
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 carbonated water pressure container 11 has a pipe 45 with a motorized valve 21 for injecting the raw material water into the carbonated water pressure container 11 and a level meter 39 which operates to stop the injection when the raw material water reaches the set water level. Is installed.
Further, in order to carbonate the raw material water in the pressure container 11 for carbonated water, the pressure container 11 for carbonated water is provided with a facility for circulating the raw material water (carbonated water) in the pressure container 11 for carbonated water. . Specifically, a circulation pump 18 for circulating the raw material water (carbonated water) in the pressure container 11 for carbonated water, and a spray nozzle 38 for jetting the circulated raw material water (carbonated water) into the pressure container 11 for carbonated water The pipes 46 and 47 connecting the circulation pump 18 and the spray nozzle 38 and the three-way valve 34 are provided.
Note that cooling means such as a heat exchanger may be separately 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 to prevent the concentration of carbon dioxide in the raw material 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。
　本実施例で、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、本実施例では、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 carbonated water is supplied from the carbonated water pressure container 11 to the ice container 12, the three-way valve 34 is switched to operate the circulation pump 18 and carbonated water is supplied to the ice container 12 through the pipes 46 and 48. . The electrically 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 container 11 for carbonated water and the pressure in the pressure-resistant ice container 12 be at the same level, the pressure container 11 for carbonated water and the pressure-resistant ice container 12 are connected by a pipe 49 having a pressure equalizing valve 33. ing.
In this embodiment, the reason that the pressure in the carbonated water pressure container 11 and the pressure in the pressure forming ice container 12 are set to the same level is to smoothly supply carbonated water from the carbonated water pressure container 11 to the pressure forming ice container 12. It is. If there is a pressure difference between the two, carbonated water will stagnate in the carbonated water pressure container 11 or carbonated water will vigorously flow toward the pressure-made ice container 12 and the carbonated water can not be supplied smoothly. I will. Also, the pressure does not necessarily have to be at the same level, and it is sufficient to control to reduce the pressure difference. For example, by setting the pressure in the carbonated water pressure container 11 a little higher than the pressure in the pressure-made ice container 12, the carbonated water supply rate can be increased.
In the present embodiment, the pressure equalizing valve 33 and the pipe 49 are used as pressure equalizing means, but other means may be used. For example, a pressure regulator such as a compressor or an open valve may be connected to each of the pressure container 11 for carbonated water and the pressure-resistant ice container 12 so as to control them so as to reduce the pressure difference between them.
　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。
　本実施例では、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 outlet (not shown) provided on the lower surface (corresponding to the “discharge outlet” of the present invention) has the same or larger diameter as the carbonated ice outlet. The motorized 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 the ball 14c fitted in the tube 14a via the pivot shaft 14d (see FIG. 3 (A) to (C)). A through hole having a diameter equal to or larger than that of the carbonated ice discharge port is formed in the central portion of the ball 14c, and the electric ball valve 14 is opened and closed by rotating the rotation shaft 14d by ± 90 °.
In this 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 naturally dropping it, which contributes to automation of a series of operations. However, when the pressure-resistant ice-making container 12 is placed horizontally, the carbonated ice outlet may be provided on the side surface of the pressure-resistant ice-making container 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 carbon dioxide gas cylinders (carbon dioxide gas feeding means) 16 and inert gas cylinders (inert gas feeding (inert gas feeding) via pipes 52, 53, 55 penetrating the flange 12a. The feeding means 17 is connected to a motor-operated valve 24 for exhaust (corresponding to the "open valve" of the present invention) and a pressure sensor 40, respectively.
The motor-operated valve 24 for exhausting is provided to reduce the pressure in the pressure-resistant ice-making container 12 and is provided on a surface other than the surface provided with the carbonated ice discharge port, that is, the opposite surface. By providing it on the surface other than the surface where the carbonated ice outlet is provided, the pressure on the motorized valve 24 side is different from the pressure on the carbonated water outlet side without interference between the carbonated ice outlet and the motorized valve 24. As a result, it is possible to smoothly discharge carbonated ice from the carbonated ice outlet.
　耐圧製氷容器１２を冷却及び加温するため、耐圧製氷容器１２の周壁１３は二重管構造とされ、二重管の内部をブラインが循環する。
　耐圧製氷容器１２を冷却する際は、冷却用ブラインタンク（本発明の「冷却手段」に相当）４３から配管５６を介して冷却用ブラインが耐圧製氷容器１２の周壁１３に流入する。耐圧製氷容器１２の周壁１３から流出した冷却用ブラインは配管５８を介して冷却用ブラインタンク４３に流入する。配管５６上には循環ポンプ１９と電動弁３１が、配管５８上には電動弁３０が設置されている。
　一方、耐圧製氷容器１２を加温する際は、加温用ブラインタンク（本発明の「加温手段」に相当）４４から配管５７を介して加温用ブラインが耐圧製氷容器１２の周壁１３に流入する。耐圧製氷容器１２の周壁１３から流出した加温用ブラインは配管５９を介して加温用ブラインタンク４４に流入する。配管５７上には循環ポンプ２０と電動弁３２が、配管５９上には電動弁２９が設置されている。 In order to cool and heat the pressure resistant ice making container 12, the peripheral wall 13 of the pressure resistant ice making container 12 has a double pipe structure, and the brine circulates inside the double pipe.
When the pressure resistant ice making container 12 is cooled, the cooling brine flows from the cooling brine tank (corresponding to the “cooling means” of the present invention) 43 into the peripheral wall 13 of the pressure resistant ice made container 12 via the pipe 56. The cooling brine that has flowed out of the peripheral wall 13 of the pressure resistant ice making container 12 flows into the cooling brine tank 43 via the pipe 58. The circulation pump 19 and the motor-operated valve 31 are provided on the pipe 56, and the motor-operated valve 30 is provided on the pipe 58.
On the other hand, when heating the pressure resistant ice making container 12, the heating brine is applied to the peripheral wall 13 of the pressure resistant ice making container 12 through the piping 57 from the heating brine tank (corresponding to the “heating means” of the present invention) 44. To flow. The heating brine that has flowed out of the peripheral wall 13 of the pressure resistant ice making container 12 flows into the heating brine tank 44 via the pipe 59. The circulation pump 20 and the motor-operated valve 32 are installed on the pipe 57, and the motor-operated valve 29 is installed on the pipe 59.
　なお、上述した電動弁を含む各機器の制御には、図示していないＰＬＣ（プログラマブル・ロジック・コントローラ）が使用される。 In addition, PLC (programmable logic controller) which is not shown in figure is used for control of each apparatus containing the electrically-driven valve mentioned above.
　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 of producing carbonated ice using the carbonated ice production apparatus 10 having the above configuration (corresponding to the “gas melted ice production method” of the present invention) will be described.
The method of producing carbonated ice is roughly divided into three processes: production of carbonated water, injection of carbonated water into a pressure-resistant ice container, and production of carbonated ice. The following will be described 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 motor operated valve 23 is opened, the vacuum pump 15 is operated, and the interior of the carbonated water pressure container 11 is evacuated.
Although this step is not essential, the impurities contained in the raw material water can be vaporized and removed by applying a vacuum.
(2) When the vacuuming is completed, the motor operated 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) The motor operated valve 21 is opened, and the raw material water is injected into the carbonated water pressure container 11. In order to increase the solubility of carbonic acid, the raw material water should be low temperature water as close to 0 ° C. as possible.
(4) When the raw water reaches the set water level, the level meter 39 operates and the motor operated 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) The motor operated valve 26 is opened, and carbon dioxide gas is fed from the carbon dioxide gas cylinder 16 to the pressure container 11 for carbonated water. The injection pressure is appropriately determined by presupposing the carbonic acid concentration of carbonic acid ice. In general, it is about 0.15 MPa to 1.0 MPa.
If the inside of the pressure container 11 for carbonated water is not evacuated in the step (1), the carbon dioxide gas having a larger specific gravity than air is accumulated from the bottom of the pressure container 11 for carbonated water by supplying the carbon dioxide gas. Carbon dioxide gas can be filled in the pressure capacity 11 for carbonated water by discharging air from an open valve or the like.
(6) When the feed of carbon dioxide gas is completed, the motor operated 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) Close the B valve of the three-way valve 34, open the A valve, and operate the circulation pump 18. Thereby, the raw material water (carbonated water) is injected from the spray nozzle 38 into the pressure container 11 for carbonated water, and the raw material water (carbonated water) in the pressure container 11 for carbonated water is circulated and mixed. Carbonated water reaches its maximum concentration in about 3 to 30 minutes depending on the amount of water.
As a method other than using such a circulation pump and a spray, for example, there is a method such as stirring or dropping raw material water on a spiral plate. That is, any method can be used as long as the contact area between carbon dioxide gas and raw water is increased.
(8) The circulation pump 18 is stopped when the carbonation work of the raw material water is completed.
［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 a pressure-resistant ice-making container]
(1) The motor-operated valve 25 is opened, the motor-operated ball valve 14 is closed, the vacuum pump 15 is operated, and the inside of the pressure-resistant ice making container 12 is evacuated.
This step is also not essential, but the vacuuming makes it possible to supply carbon dioxide gas efficiently in the next step.
(2) When the vacuuming is completed, the motor operated 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 motor operated valve 27 is opened to feed carbon dioxide gas from the carbon dioxide gas cylinder 16 to the pressure-resistant ice making container 12. The injection pressure is about 0.15 MPa to about 1.0 MPa as described above.
When the inside of the pressure-resistant ice making container 12 is not evacuated in the step (1), the carbon dioxide gas having a specific gravity larger than that of air is accumulated from the bottom of the pressure forming ice container 12 by supplying carbon dioxide gas. By evacuating the air, carbon dioxide gas can be filled in the pressure-resistant ice making container 12.
(4) When the feed of carbon dioxide gas is completed, the motor operated 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、本実施例では均圧弁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 motor operated valve 22 and the pressure equalizing valve 33 are opened, the A valve of the three-way valve 34 is closed and the B valve is opened to operate the circulation pump 18 to make the pressure container 11 for carbon dioxide gas pressure resistant. Supply carbonated water. At this time, a space of at least 20% or more of the volume of the carbonated water is provided above the pressure-resistant ice making container 12 in order to prevent the container breakage due to the freezing and expansion of the carbonated water.
In the present embodiment, the carbonated water supply is started after the pressure equalizing valve 33 is opened, but the timing of the two may be simultaneous. Alternatively, the pressure equalizing valve 33 may be opened after the start of the carbonated water supply.
(6) When the supply of carbonated water from the carbonated water pressure container 11 to the pressure-made ice container 12 is completed (water injection to the set water level), the circulation pump 18 is stopped and the motor operated valve 22 and the pressure 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。 [Manufacture of carbonated ice]
(1) The motor operated valve 28 is opened, and the inert gas is supplied 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 carbonated water in this manner, carbon dioxide gas is less likely to escape from the raw material water, and the carbon dioxide concentration of carbonated ice can be maintained.
Note that the gas supplied is not limited to the inert gas. For example, a compressor may be used to pressurize with air. Alternatively, the 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) Close the motor-operated valve 28 when the feed of the inert gas is completed.
（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 motor-operated valve 31 and the motor-operated valve 30 are opened, the circulation pump 19 is operated, and the pressure-resistant ice container 12 (carbonated water) is cooled by the cooling brine from the cooling brine tank 43 to produce carbonated ice (hereinafter referred to as Mark as "ice making". The temperature of the cooling brine is about -10.degree. C. to -40.degree.
(4) When ice making is completed, the motor-operated valve 31 and the motor-operated valve 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) Open the motor-operated ball valve 14 and the motor-operated valve 24. As a result, the pressure in the pressure-proof ice making container 12 can be reduced, and carbon dioxide can be prevented from being crushed from the pressure-proof ice making container vigorously discharged from the carbon dioxide ice outlet.
(6) Open the motor-operated valve 32 and the motor-operated valve 29, operate the circulation pump 20, heat the pressure-resistant ice container 12 (carbonated ice) with the heating brine from the heating brine tank 44, Peeling (hereinafter referred to as “de-icing”) is started from the inner surface of the ice making container 12. The temperature of the heating brine is about 10 ° C to 40 ° C. When the carbonated ice is peeled off from the inner surface of the pressure resistant ice making container 12, the carbonated ice is discharged to the outside from the electric ball valve 14 through the carbonated ice outlet by its own weight.
(7) When the deicing is completed, the motor-operated valve 32 and the motor-operated valve 29 are closed, and the circulation pump 20 is stopped.
