しかしながら、特許文献１のようなオゾン水を、オゾン水タンクと混合循環流路との間に循環させるオゾン水供給装置では、混合ポンプの熱により水温が上昇しやすいという欠点があった。具体的には、この水温は15〜40℃となっていた。そのため、オゾン水に溶解したオゾンの分解が促進され、オゾン水の製造効率が低下する要因となっていた。また、従来のオゾン水供給装置では、装置外部に供給するオゾン水の温度も低くするのが困難であったので、例えば製氷機にオゾン水を供給する場合には、製氷機に大きな負担がかかるという問題点もあった。   However, the ozone water supply device that circulates ozone water between the ozone water tank and the mixing circulation channel as in Patent Document 1 has a drawback that the water temperature is likely to rise due to the heat of the mixing pump. Specifically, the water temperature was 15 to 40 ° C. Therefore, decomposition | disassembly of the ozone melt | dissolved in ozone water was accelerated | stimulated, and it became a factor by which the production efficiency of ozone water fell. Further, in the conventional ozone water supply device, it is difficult to reduce the temperature of the ozone water supplied to the outside of the device. For example, when supplying ozone water to an ice making machine, a large burden is placed on the ice making machine. There was also a problem.

The mixing circulation passage is configured to supply ozone water to the ozone water tank and the mixing circulation flow. A circulation pump for circulating between the passage and a mixer for mixing ozone gas; and an ozone water cooler is provided between the circulation pump and the mixer.
Moreover, ozone water is cooled so that it may be kept at 2-10 degreeC with the said ozone water cooler.
Further, after the ozone concentration in the ozone water tank reaches a predetermined value and is cooled by the ozone water cooler and the ozone water reaches a predetermined low temperature, A supply flow path for supplying cooling ozone water to the ice making machine at a time is connected to the ozone water tank.

本発明のオゾン水供給装置によれば、オゾン水に溶解したオゾンの分解を軽減しつつ、オゾン水を循環させながらオゾンガスの混合を繰り返してオゾン水中のオゾン濃度を上昇させることができるので、オゾン濃度の高濃度安定化を図ることができる。   According to the ozone water supply device of the present invention, the ozone concentration in the ozone water can be increased by repeating the mixing of ozone gas while circulating the ozone water while reducing the decomposition of the ozone dissolved in the ozone water.

ミキサー２は、オゾン水とオゾンガスとを混合させるものであり、循環ポンプ３の下流側に位置している。このミキサー２の上流側（かつ循環ポンプ３の下流側）には、オゾンガス発生装置５にて発生させたオゾンガスをミキサー２に送るためのオゾンガス供給流路Ｂが接続されている。 The circulation pump 3 serves as a drive source for circulating ozone water between the ozone water tank 1 and the mixing circulation passage A, and for example, a pump with a circulation flow rate of 15 L / min is used.
The mixer 2 mixes ozone water and ozone gas, and is located downstream of the circulation pump 3. An upstream side of the mixer 2 (and a downstream side of the circulation pump 3) is connected to an ozone gas supply channel B for sending ozone gas generated by the ozone gas generator 5 to the mixer 2.

ここで、本発明では、オゾン水タンク１から取り出したオゾン水にオゾンガスを混合しつつ循環させる混合循環流路Ａの途中に、オゾン水冷却機４が介設されている。具体的には、循環ポンプ３とミキサー２との間（かつオゾンガス供給流路Ｂとの接続点よりも上流側）に、オゾン水冷却機４が設けられている。

Further, a flow path leading to a drain valve 11 for discharging ozone water in the ozone water tank 1 during maintenance is provided at the lower part of the ozone water tank 1.

次に、本発明に係るオゾン水供給装置の動作について説明する。
まず最初に、原料水供給弁10を開けて、オゾン水タンク１に原料水を供給する。そして、レベルセンサ９がオゾン水タンク１内の満水を検知したとき（全容量のうち例えば94％ほどに満たされたことを検知したとき）に原料水供給弁10を閉じて給水停止する。
次に、循環ポンプ３と、オゾンガス発生装置５と、オゾン水冷却機４と、を作動させて、オゾン水を循環させながらオゾンガスとオゾン水との混合を繰り返す。このオゾン水の循環は、例えば８〜25min かけて行う。また、このオゾン水を循環させる際には、同時にオゾン水冷却機４によってオゾン水の冷却を行う。また、オゾン水を循環させている間、電磁弁８を開き、排オゾン処理装置７にてオゾン水タンク１及び混合循環流路Ａ内のオゾン水に溶解しきれなかった余分なオゾンガスを処理する。 Next, the operation of the ozone water supply device according to the present invention will be described.
First, the raw water supply valve 10 is opened to supply raw water to the ozone water tank 1. Then, when the level sensor 9 detects that the ozone water tank 1 is full (when it is detected that, for example, about 94% of the total capacity has been filled), the raw water supply valve 10 is closed to stop water supply.
Next, the circulation pump 3, the ozone gas generator 5, and the ozone water cooler 4 are operated to repeat the mixing of the ozone gas and the ozone water while circulating the ozone water. The ozone water is circulated for 8 to 25 minutes, for example. Further, when circulating this ozone water, the ozone water cooler 4 simultaneously cools the ozone water. Further, while the ozone water is circulated, the solenoid valve 8 is opened, and the waste ozone treatment device 7 treats the excess ozone gas that could not be dissolved in the ozone water in the ozone water tank 1 and the mixing circulation channel A. .

そして、オゾン水タンク１内のオゾン水のオゾン濃度が所定値（例えば10〜50ppm ）に到達し、かつ、オゾン水冷却機４によって冷却されてオゾン水が所定の低温度（２〜10℃）に到達した後、所定オゾン濃度、所定の低温度となった冷却オゾン水を、エアー加圧口ａからガスを送ってオゾン水タンク１内の冷却オゾン水に圧力（例えば 0.2MPa ）を加えながら、オゾン水供給流路Ｄを介して製氷機６に一度に供給する。
以上の動作を繰り返すことにより、製氷機６に間欠的に冷却オゾン水が供給されるように構成する。 Then, the ozone concentration of the ozone water in the ozone water tank 1 reaches a predetermined value (for example, 10 to 50 ppm) and is cooled by the ozone water cooler 4 so that the ozone water has a predetermined low temperature (2 to 10 ° C.). Then, the cooling ozone water having a predetermined ozone concentration and a predetermined low temperature is sent from the air pressurizing port a and the pressure (for example, 0.2 MPa) is applied to the cooling ozone water in the ozone water tank 1. The ice maker 6 is supplied at once through the ozone water supply channel D.
By repeating the above operation, the cooling ozone water is intermittently supplied to the ice making machine 6.

なお、本発明は、上述の実施の形態に限定されず、本発明の要旨を逸脱しない範囲で設計変更可能である。例えば、循環ポンプ３の上流側にオゾン水冷却機４を設けるも自由である。また、（オゾン水）供給流路Ｄを、オゾン水タンク１内の冷却オゾン水を一度に製氷機６に供給するための供給流路とするのではなく、製氷機６に代えて、医療用品や食品を殺菌する装置にオゾン水を供給するための供給流路とするのも好ましい。また、オゾン水供給流路Ｄを、ポンプ３とオゾン水冷却機４の間に接続（分岐）させたり、ポンプ３の吸入配管に接続（分岐）させることも、自由である。また、弁10, 11, ８は、手動であっても、自動（電磁弁）であっても、自由に選択可能である。 The present invention is not limited to the above-described embodiment, and the design can be changed without departing from the gist of the present invention. For example, the ozone water cooler 4 may be provided upstream of the circulation pump 3. Further, the (ozone water) supply flow path D is not a supply flow path for supplying the cooling ozone water in the ozone water tank 1 to the ice making machine 6 at the same time. It is also preferable to use a supply channel for supplying ozone water to a device for sterilizing food. Further, the ozone water supply channel D can be freely connected (branched) between the pump 3 and the ozone water cooler 4 or connected (branched) to the suction pipe of the pump 3. Further, the valves 10, 11 and 8 can be freely selected, whether manually or automatically (solenoid valve).

以上のように、本発明に係るオゾン水供給装置20は、オゾン水タンク１から取り出したオゾン水にオゾンガスを混合しつつ循環させる混合循環流路Ａの途中に、オゾン水冷却機４を介設するので、オゾン水冷却機４にて、オゾン水タンク１及び混合循環流路Ａ中のオゾン水を冷却することができる。これにより、オゾン水に溶解したオゾンの分解を軽減しつつ、オゾン水を循環させながらオゾンガスの混合を繰り返してオゾン水中のオゾン濃度を上昇させることができる。その結果、オゾン濃度の高濃度安定化を図ることができる。   As described above, the ozone water supply device 20 according to the present invention is provided with the ozone water cooler 4 in the middle of the mixing circulation passage A that circulates while mixing ozone gas with the ozone water taken out from the ozone water tank 1. Therefore, the ozone water cooler 4 can cool the ozone water in the ozone water tank 1 and the mixing circulation channel A. Thereby, mixing of ozone gas can be repeated and the ozone concentration in ozone water can be raised, circulating ozone water, reducing the decomposition | disassembly of the ozone melt | dissolved in ozone water. As a result, high concentration stabilization of ozone concentration can be achieved.

また、オゾン水を貯蓄するオゾン水タンク１と、オゾン水タンク１に原料水を供給する原料水供給流路Ｃと、オゾン水タンク１から取り出したオゾン水にオゾンガスを混合して再びオゾン水タンク１に戻す混合循環流路Ａと、オゾン水タンク１から取り出したオゾン水を外部に供給するオゾン水供給流路Ｄと、を備え、混合循環流路Ａは、オゾン水をオゾン水タンク１と混合循環流路Ａとの間で循環させるための循環ポンプ３と、オゾンガスを混合するためのミキサー２と、を有し、さらに、循環ポンプ３とミキサー２との間に、オゾン水冷却機４を設けるので、オゾン水冷却機４にて、オゾン水タンク１及び混合循環流路Ａ中のオゾン水を冷却することができる。これにより、オゾン水に溶解したオゾンの分解を軽減しつつ、オゾン水を循環させながらオゾンガスの混合を繰り返してオゾン水中のオゾン濃度を上昇させることができる。その結果、オゾン濃度の高濃度安定化を図ることができる。
また、循環ポンプ３とミキサー２との間にオゾン水冷却機４を設けることによって、循環ポンプ３通過直後の温度が上昇したオゾン水を効果的に冷却することができる。また、ミキサー２内で、冷却された直後のオゾン水とオゾンガスとを混合させることができるので、オゾン水へのオゾンの溶解が効率的に行われるように構成することができる。 The ozone water tank 1 for storing ozone water, the raw material water supply channel C for supplying raw water to the ozone water tank 1, and the ozone water mixed again with the ozone water taken out from the ozone water tank 1 are again used. 1 is provided with a mixing circulation channel A that is returned to 1, and an ozone water supply channel D that supplies ozone water extracted from the ozone water tank 1 to the outside. The mixing circulation channel A supplies ozone water to the ozone water tank 1. A circulation pump 3 for circulating between the mixing circulation flow path A and a mixer 2 for mixing ozone gas, and an ozone water cooler 4 between the circulation pump 3 and the mixer 2. Therefore, the ozone water cooler 4 can cool the ozone water in the ozone water tank 1 and the mixing circulation channel A. Thereby, mixing of ozone gas can be repeated and the ozone concentration in ozone water can be raised, circulating ozone water, reducing the decomposition | disassembly of the ozone melt | dissolved in ozone water. As a result, high concentration stabilization of ozone concentration can be achieved.
Further, by providing the ozone water cooler 4 between the circulation pump 3 and the mixer 2, it is possible to effectively cool the ozone water whose temperature immediately after passing through the circulation pump 3 has increased. Further, since the ozone water and the ozone gas immediately after being cooled can be mixed in the mixer 2, it can be configured such that the ozone is efficiently dissolved in the ozone water.

また、オゾン水冷却機４にて、２〜10℃に保たれるようにオゾン水を冷却することによって、オゾン水へのオゾンの溶解がより効率的に行われるように構成することができる。 また、オゾン水タンク１内のオゾン水のオゾン濃度が所定値に到達し、かつ、オゾン水冷却機４によって冷却されてオゾン水が所定の低温度に到達した後に、オゾン水タンク１内の冷却オゾン水を、一度に製氷機６に供給するための（オゾン水）供給流路Ｄをオゾン水タンク１に連設することによって、オゾン水供給装置20から製氷機６に送り込むオゾン水の温度と製氷機６内で製造されるオゾン含有の氷の温度との温度差が小さくなるように構成することができる。これにより、氷内へのオゾンの混入率を向上でき、魚や野菜等の鮮度を長期間維持できるオゾン入りの氷を効率よく製造することができる。このように、製氷機６にかかる負担が小さくて済み、製氷機６に使用されるオゾン水を供給するのに好適なオゾン水供給装置とすることができる。   Further, by cooling the ozone water so as to be kept at 2 to 10 ° C. by the ozone water cooler 4, it can be configured such that the ozone is dissolved more efficiently in the ozone water. Further, after the ozone concentration in the ozone water tank 1 reaches a predetermined value and is cooled by the ozone water cooler 4 and the ozone water reaches a predetermined low temperature, the ozone water tank 1 is cooled. By connecting the ozone water tank 1 with an (ozone water) supply channel D for supplying ozone water to the ice maker 6 at a time, the temperature of the ozone water fed from the ozone water supply device 20 to the ice maker 6 is The temperature difference from the temperature of the ozone-containing ice produced in the ice making machine 6 can be reduced. Thereby, the mixing rate of ozone into ice can be improved, and ozone-containing ice that can maintain the freshness of fish and vegetables for a long period of time can be efficiently produced. Thus, the burden on the ice making machine 6 can be reduced, and an ozone water supply device suitable for supplying ozone water used for the ice making machine 6 can be obtained.
