Abstract
Description
海苔巻き、寿司、おにぎりなど、日本においては海苔が使用される食品は多く存在し、海苔は日本食に欠かせない存在であることから、海苔生産量の低下は深刻な問題である。
すなわち、特許文献1に記載された海藻類養殖装置301は、その本体として上部に開口部が形成された、有底で円筒形の水槽302を備える。
また、水槽302の上部開口部付近には、注水管303が連通して取付けられている。
また、筒状体305の上下方向の全体にわたって、複数の開孔306が形成されている。
また、水槽302の底部であり、かつ、筒状体305の内側には、吸水口308が形成されている。
また、気泡は底層部に滞留しないので、水槽の底層部の藻類に充分に二酸化炭素もしくは酸素が供給されていなかった。
その結果、藻類の育成効率が充分ではなかった。
また、渦状の流れによって、光合成で発生した酸素気泡を藻類から分離し易くなり、藻類が二酸化炭素を吸収し易くなる。
また、藻類槽が複数存在するときには、作業負担を軽減できる。
また、渦状の流れによって、光合成で発生した酸素気泡を海苔葉体から分離し易くなり、海苔葉体が二酸化炭素を吸収し易くなる。
また、溶解液を流すときには海苔葉体も一緒に流している場合もあるものとする。
本発明に係る藻類育成方法は、藻類の育成効率を向上させることができる。
図1は、本発明を適用した藻類育成装置の一例を説明する概略図である。また、図2は、図1のA-A線に沿って切断された、本発明を適用した藻類育成装置が備える、藻類槽と供給部の概略断面図である。また、図3は、本発明を適用した藻類育成装置が備える供給部の第1のカバー体の第1の放流口から育成水と海苔葉体が放流される様子の一例を示す概略図である。
ここで、気体溶解部20は、液体例えば海洋深層水に二酸化炭素及び酸素を溶解して、溶解液である育成水25を生成可能である。
また、気体溶解部20には、気体溶解部20の内部に酸素を供給するための酸素供給管22が連通して接続されている。
また、酸素供給管22には、例えば供給圧1.2hPaで気体溶解部20内へ酸素を供給できるよう、図示していない供給圧調整機構を有する。
すなわち、海洋深層水を、二酸化炭素や酸素で満たされた気体溶解部20内の雰囲気へ、この二酸化炭素の圧力や酸素の圧力より低い圧力に維持して流入させて、二酸化炭素や酸素と接触させ、二酸化炭素や酸素を海洋深層水に溶解するのである。
これにより、二酸化炭素溶存量が高い、二酸化炭素が溶解した育成水25が得られる。
これにより、酸素溶存量が高い、酸素が溶解した育成水25が得られる。
また、気体溶解部は必ずしも酸素を溶解しなくてもよい。
ここで、藻類槽30は、育成水25を収容可能である。また、育成水25には藻類例えば海苔葉体73が入れられるので、藻類槽30は、育成水25に入れられた海苔葉体73も収容可能である。
また、海苔葉体の代わりにスピルリナなどの単細胞微細藻類を育成水に入れて、単細胞微細藻類を育成することもできる。
すなわち、藻類槽30は一方向に延びており、かつ、延びた方向の両端が閉塞しており、かつ、延びた方向に対して略直交する方向における断面形状が略円形である円筒形状を有する。
すなわち、気体溶解部20は、藻類槽30の外部の圧力よりも高い圧力を有する育成水25を生成可能である。
また、複数の第2のLED41も、藻類槽30が延びる方向と同じ方向に、互いに所定の間隔例えば1mの間隔を設けて直列的に配列されている。
また、藻類槽30が延びる方向に対して略直交していると共に対向する第1のLED40の配列と第2のLED41の配列とを結ぶ線におけるLEDの数は1つである。すなわち、第1のLED40と対向する位置に第2のLED41は配置されておらず、一方、第2のLED41と対向する位置に第1のLED40も配置されていない。
すなわち、第1のLED40及び第2のLED41は藻類槽30の壁に埋め込まれている。
また、第1のLED及び第2のLEDは発光体の一例である。
特に二酸化炭素濃度が2.0%である育成水を使用した場合、自然海水を使用した場合に比べて藻類の生長率が約24倍となる。
また、制御部44は、気体溶解部20に取付けられている。
また、制御部44は、酸素濃度センサ43が検知した酸素濃度が所定の値より小さい場合、例えば、気体溶解部20に酸素供給管22との連通状態を「開」状態にさせ、さらに酸素を育成水25に溶解させる制御が可能である。
ここで、供給部50は、気体溶解部20に連通している。
すなわち、育成水供給管23の一端が、気体溶解部20に連通して接続されており、育成水供給管23の一端とは反対側の他端が、供給部50に連通して接続されている。
その結果、育成水25は、図2に示すように渦状の流れとなって藻類槽30内を流れる。
すなわち、供給部50は、供給管51を有する。
ここで、藻類槽30の内側面30Aには藻類槽30の内部と外部とを連通する複数の貫通穴が形成されているが、供給管51は複数の分岐供給管を介して、複数の貫通穴それぞれに連通して接続されている。
例えば、図2に示すように、藻類槽30に形成された第1の供給用貫通穴31に、第1の分岐供給管51Aの一端が連通して接続されており、第1の分岐供給管51Aの一端とは反対側の他端は供給管51に連通して接続されている。
なお、第1の供給用貫通穴中心軸線は、実体のない想像上の線である。
また、第1のカバー体52Aは、第1の分岐供給管51Aと連通する第1の放流空間54Aを藻類槽30の内側面30Aとの間に形成している。
また、第1のカバー体52Aの、第1の放流空間54Aに向いた面とは反対側の面は湾曲している。
従って、供給部50は、藻類槽30の湾曲した内側面30Aに沿って育成水25を流すことができる。
分岐供給管の数や、それに対応するカバー体の数を増やすことで、さらに強い渦状の流れを発生させることができる。
ここで、循環ポンプ部60は、藻類槽30と気体溶解部20とに連通している。
ここで、藻類槽30の一方の端部には、藻類槽30の内部と外部とを連通する貫通穴である吸出用貫通穴32が形成されており、吸出管61の一端は吸出用貫通穴32に連通して接続されている。
また、循環ポンプ部60は、吸出された育成水25と海苔葉体73を気体溶解部20へ送出し、送出したときの力で育成水25と海苔葉体73に、気体溶解部20と供給管51を通過させて、第1の分岐供給管51Aと、第2の分岐供給管51B、及び第3の分岐供給管51Cから、育成水25と海苔葉体73を藻類槽30内へ注入可能である。
ここで、海苔葉体供給部70は、供給部50と連通しており、かつ、供給部50に海苔葉体73を供給可能である。
ここで、育成水供給管23は供給部50に連通して接続されているので、海苔葉体供給部70は海苔葉体供給管71と育成水供給管23を介して供給部50と連通している。
また、育成水25と海苔葉体73が藻類槽30から吸出される吸出箇所である吸出用貫通穴32が形成された藻類槽30の一方の端部の位置は、この一方の端部とは反対側の他方の端部の位置よりも鉛直方向において下方に存在する。
すなわち、藻類槽30は、高さが異なる一組の藻類槽支持部35によって両端部が支持され、傾斜して配置されている。
また、排出管36の一端とは反対側の他端は、約15cmの長さにまで生長した海苔葉体73を育成水25と共に貯留するための海苔貯留槽80に連通して接続されている。
空気抜用貫通穴34は、藻類槽30から、排出管36によって育成水25と海苔葉体73を排出するときに藻類槽30内の空気を抜くための貫通穴である。
ここで、液肥注入部90は、供給部50と連通しており、かつ、供給部50に液肥を注入可能である。
ここで、育成水供給管23は供給部50に連通して接続されているので、液肥注入部90は液肥供給管91と育成水供給管23を介して供給部50と連通している。
ここで、海水注入部100は、気体溶解部20と連通している。
すなわち、海水供給管103の一端が海水注入部100に連通して接続されており、海水供給管103の一端とは反対側の他端が、気体溶解部20に連通して接続された送出管62に、連通して接続されている。
ここで、殺菌処理部106は、海水吸引管101に連通して接続されており、海水吸引管101を流れる海洋深層水を殺菌処理可能である。
また、殺菌処理部106は、具体的には例えばオゾンまたは紫外線を利用して、海洋深層水を殺菌処理する。
また、液体として必ずしも海洋深層水を使用しなくてもよく、例えば地下水を使用することもできる。
また、本発明の藻類育成装置10は、排出管36に取付けられた排出用制御バルブ37を備える。
また、本発明の藻類育成装置10は、空気抜用貫通穴34に取付けられた空気抜用制御バルブ38を備える。
また、本発明の藻類育成装置10は、海苔葉体供給管71に取付けられた海苔葉体供給用制御バルブ72を備える。
また、本発明の藻類育成装置10は、海水供給管103に取付けられた海水供給用制御バルブ104を備える。
また、スマートフォン107が発信する制御信号に基づいて排出用制御バルブ37を制御し、藻類槽30から排出される、育成水25及び育成水25に入れられた海苔葉体73の流量を制御できる。
また、スマートフォン107が発信する制御信号に基づいて送出用制御バルブ63を制御し、藻類槽30から吸出されて気体溶解部20へ送出される、育成水25及び育成水25に入れられた海苔葉体73の流量を制御できる。
また、スマートフォン107が発信する制御信号に基づいて液肥供給用制御バルブ92を制御し、供給部50への液肥の供給量を制御できる。
しかし、カバー体があれば、カバー体が無く供給管を藻類槽の内側面から突出させた構成よりも、藻類が供給部に引っ掛かり難いので好ましい。
また、本発明の藻類育成装置は、必ずしもスマートフォンすなわち携帯端末が発信する信号に基づいて制御可能な制御バルブを備えていなくてもよい。
すなわち、本発明の藻類育成方法は、液体例えば海洋深層水に二酸化炭素を溶解可能な気体溶解部20において、海洋深層水に海洋深層水の圧力よりも高い圧力を有する二酸化炭素を溶解して溶解液である育成水25を生成する、溶解液生成工程である育成水生成工程を備える。
また、本発明の藻類育成方法は、育成水25と育成水25に入れられた海苔葉体73を収容した藻類槽30の内部へ向けて発光する発光工程を備える。
また、本発明の藻類育成方法は、排出された海苔葉体を切断する切断工程を備える。
また、海苔葉体供給工程は、排出工程で排出された海苔葉体73の長さよりも短い長さを有する海苔葉体73を供給する。
なお、図1において、細い矢印は液体と固体の流れを示し、太い矢印は気体の流れを示す。
このとき、海苔葉体供給用制御バルブ72によって、藻類槽30に供給される海苔葉体73の量を調整する。
このとき、殺菌処理部106が海水吸引管101を流れる海洋深層水を殺菌処理する。
このとき、気体溶解部20において、注入された海洋深層水に海洋深層水の圧力よりも高い圧力を有する酸素も溶解する。
このとき、吸出された育成水25と海苔葉体73は吸出管61を通り、さらに送出管62を通って気体溶解部20へと送られる。
このとき、供給部50は、藻類槽30の内側面30Aの湾曲方向に対して斜めに交差する方向に沿って育成水25と海苔葉体73を放流する。
すなわち、循環工程と放流工程を実施する。
ここで、例えば海苔葉体73を藻類槽30の外部から撮像しておき、撮像して得られた画像を解析することによって海苔葉体73の長さを測定することができる。
また、渦状の流れによって、光合成で発生した酸素気泡を藻類から分離し易くなり、藻類が二酸化炭素を吸収し易くなる。
特に、海苔葉体を使用するので、海苔の胞子や糸状体を供給して育成する方法よりも早く育成を完了させることができる。
