この異物除去機構62は、本体水槽40と排出水槽42の上方に回動軸63,64を架設し、各回動軸63,64の両端部にスプロケット65,66,67,68を取付け、各スプロケット65,66,67,68に連動チェーン69,70を巻回し、両連動チェーン69,70の間にスクレーパー71を下方へ向けて架設しており、排出水槽42の上方に架設した回動軸64には、駆動モータ72を連動機構73を介して連動連結している。なお、図中、74,75,76,77は軸支持体である。 The foreign matter removing mechanism 62 has rotating shafts 63 and 64 installed above the main body water tank 40 and the discharge water tank 42, and sprockets 65, 66, 67, and 68 are attached to both ends of the rotating shafts 63 and 64. The interlocking chains 69, 70 are wound around 65, 66, 67, 68, and a scraper 71 is installed downward between the interlocking chains 69, 70, and a rotating shaft 64 is provided above the discharge water tank 42. In addition, the drive motor 72 is interlocked and connected via an interlocking mechanism 73. In the figure, 74, 75, 76 and 77 are shaft supports.

次に、海水吸引供給流路５の構造について説明すると、海水吸引供給流路５は、図１に示すように、中途部に切換弁からなる流路切換機構78を介設しており、この流路切換機構78の一方側に海苔貯蔵槽２に連通する海水吸引パイプ28と海水供給パイプ30を接続するとともに、流路切換機構78の他方側に海苔貯蔵槽３に連通する海水吸引パイプ29と海水供給パイプ31を接続し、さらに、流路切換機構78に海水貯留槽４に連通する海水流入パイプ47と海水流出パイプ59を接続している。 Next, the structure of the seawater suction supply flow path 5 will be described. As shown in FIG. 1, the seawater suction supply flow path 5 is provided with a flow path switching mechanism 78 including a switching valve in the middle. A seawater suction pipe 28 that communicates with the laver storage tank 2 and a seawater supply pipe 30 are connected to one side of the flow path switching mechanism 78 and a seawater suction pipe 29 that communicates with the seaweed storage tank 3 to the other side of the flow path switching mechanism 78. And a seawater supply pipe 31 are connected to each other, and a seawater inflow pipe 47 and a seawater outflow pipe 59 communicating with the seawater storage tank 4 are connected to the flow path switching mechanism 78.
そして、海水吸引供給流路５は、流路切換機構78によって海苔貯蔵槽２に連通する海水吸引パイプ28と海水貯留槽４に連通する海水流入パイプ47とを連通連結するとともに、海苔貯蔵槽２に連通する海水供給パイプ30と海水貯留槽４に連通する海水流出パイプ59とを連通連結して、海苔貯蔵槽２と海水貯留槽４との間で海水を循環するようにし、或いは、流路切換機構78によって海苔貯蔵槽３に連通する海水吸引パイプ29と海水貯留槽４に連通する海水流入パイプ47とを連通連結するとともに、海苔貯蔵槽３に連通する海水供給パイプ31と海水貯留槽４に連通する海水流出パイプ59とを連通連結して、海苔貯蔵槽３と海水貯留槽４との間で海水を循環するようにしている。 The seawater suction supply flow path 5 is connected to the seawater suction pipe 28 communicated with the seaweed storage tank 2 and the seawater inflow pipe 47 communicated with the seawater storage tank 4 by the flow path switching mechanism 78, and the seaweed storage tank 2 The seawater supply pipe 30 that communicates with the seawater and the seawater outflow pipe 59 that communicates with the seawater storage tank 4 are connected in communication to circulate seawater between the laver storage tank 2 and the seawater storage tank 4, or The seawater suction pipe 29 communicating with the seaweed storage tank 3 and the seawater inflow pipe 47 communicating with the seawater storage tank 4 are connected to each other by the switching mechanism 78, and the seawater supply pipe 31 and seawater storage tank 4 communicating with the seaweed storage tank 3 are connected. A seawater outflow pipe 59 that communicates with the seawater is communicatively connected to circulate seawater between the laver storage tank 3 and the seawater storage tank 4.
ここで、流路切換機構78は、手動操作により流路を切り換えるようにしてもよく、また、タイマーによって定期的に流路を切り換えるようにしてもよい。特に、一方の海苔貯蔵槽2,3だけから連続して海水を吸引すると、一方の海苔貯蔵槽2,3の吸引水槽24,25の内部の海水が少なくなって、海水の吸引が一時的に停止してしまうおそれがあるが、流路切換機構78によって定期的に流路を切り換えることで、吸引水槽24,25の内部の海水が交互に少なくなり、一方の海苔貯蔵槽2,3から海水を吸引している間に他方の海苔貯蔵槽2,3の吸引水槽24,25の内部の海水量が回復することになり、両方の海苔貯蔵槽2,3の海水を連続して安定して循環させることができる。 Here, the flow path switching mechanism 78 may switch the flow path by a manual operation, or may switch the flow path periodically by a timer. In particular, if seawater is continuously sucked from only one of the laver storage tanks 2, 3, the seawater inside the suction water tanks 24, 25 of one of the laver storage tanks 2, 3 decreases, and the suction of seawater is temporarily Although there is a risk of stopping, by periodically switching the flow path by the flow path switching mechanism 78, the seawater inside the suction water tanks 24, 25 will alternately decrease, and the seaweed storage tanks 2, 3 will The amount of seawater in the suction tanks 24 and 25 of the other laver storage tanks 2 and 3 will be restored while the seawater in both laver storage tanks 2 and 3 is continuously stabilized. It can be circulated.
また、海水吸引供給流路５は、海水流出パイプ59の中途部に殺菌装置80を介設している。この殺菌装置80は、活性炭や紫外線照射器を内蔵しており、海水流出パイプ59を通って海苔貯蔵槽2,3に供給される海水中の有機物を分解し脱臭・除菌するようにしている。これによっても、海苔貯蔵槽2,3に貯蔵される海苔原藻の鮮度を向上させることができる。 Further, the seawater suction supply flow path 5 is provided with a sterilizer 80 in the middle of the seawater outflow pipe 59. This sterilizer 80 incorporates activated carbon and an ultraviolet irradiator, and decomposes and deodorizes and disinfects the organic matter in the seawater supplied to the laver storage tanks 2 and 3 through the seawater outflow pipe 59. . Also by this, the freshness of the seaweed raw algae stored in the seaweed storage tanks 2 and 3 can be improved.
次に、海水循環流路６の構造について説明すると、海水循環流路６は、図１に示すように、海水貯留槽４に接続した海水吸引パイプ51に海水冷却装置７を接続するとともに、この海水冷却装置７に連通パイプ79を接続し、この連通パイプ79に酸素供給装置８を接続し、この酸素供給装置８に海水供給パイプ49を接続し、この海水供給パイプ49に海水貯留槽４を接続している。なお、酸素供給装置８は、オゾンを海水中に供給するようにして、オゾンによる殺菌を行えるように構成してもよい。 Next, the structure of the seawater circulation channel 6 will be described. As shown in FIG. 1, the seawater circulation channel 6 connects the seawater cooling device 7 to the seawater suction pipe 51 connected to the seawater storage tank 4, and this A communication pipe 79 is connected to the seawater cooling device 7, an oxygen supply device 8 is connected to the communication pipe 79, a seawater supply pipe 49 is connected to the oxygen supply device 8, and the seawater storage tank 4 is connected to the seawater supply pipe 49. Connected. In addition, you may comprise the oxygen supply apparatus 8 so that ozone can be sterilized by supplying ozone in seawater.
そして、海水循環流路６は、海水貯留槽４の内部の海水を海水吸引パイプ51から吸引し、海水冷却装置７によって所定の温度に冷却するとともに、酸素供給装置８によって酸素を飽和溶解濃度まで供給し、再び海水貯留槽４の内部に戻すようにしている。 The seawater circulation channel 6 sucks the seawater inside the seawater storage tank 4 from the seawater suction pipe 51 and cools it to a predetermined temperature by the seawater cooling device 7, and oxygen is saturated to a saturated dissolution concentration by the oxygen supply device 8. It is supplied and returned to the inside of the seawater storage tank 4 again.
海水循環システム１は、以上に説明したように構成しており、海苔貯蔵槽2,3に設けた吸引ポンプ26,27と海水貯留槽４に設けた吸引ポンプ50及び吸引ポンプ58と流路切換機構78を駆動制御することによって、海苔貯蔵槽2,3と海水貯留槽４との間で海水を循環させるとともに、海水貯留槽４の内部の海水を海水冷却装置７及び酸素供給装置８を介して循環させるようにしている。 The seawater circulation system 1 is configured as described above, and the suction pumps 26 and 27 provided in the laver storage tanks 2 and 3 and the suction pump 50 and the suction pump 58 provided in the seawater storage tank 4 and the channel switching. By driving and controlling the mechanism 78, the seawater is circulated between the laver storage tanks 2, 3 and the seawater storage tank 4, and the seawater inside the seawater storage tank 4 is passed through the seawater cooling device 7 and the oxygen supply device 8. To circulate.
すなわち、海苔貯蔵槽2,3に海苔原藻とともに貯蔵されている海水は、吸引ポンプ26,27によって吸引され、海水吸引パイプ28,29、流路切換機構78、海水流入パイプ47を通って海水貯留槽４の流入側小水槽44に流入する。その後、海水は、仕切壁43をオーバーフローして流入側小水槽44から流出側大水槽45へと流れ、その際に、異物除去機構62によって異物が除去される。その後、流出側大水槽45に貯留された海水は、吸引ポンプ50によって吸引され、海水吸引パイプ51、海水冷却装置７、連通パイプ79、酸素供給装置８、海水供給パイプ49を通って再び海水貯留槽４の流入側小水槽44に流入する。また、流出側大水槽45に貯留された海水は、水圧によって海水流出口52から連通パイプ53を通って貯留水槽55に流入し、仕切壁54をオーバーフローしてオーバーフロー水槽56に流入し、その後、吸引ポンプ58によって吸引され、海水流出パイプ59、流路切換機構78、海水供給パイプ30,31を通って海苔貯蔵槽2,3に流入する。 That is, the seawater stored in the seaweed storage tanks 2 and 3 together with the seaweed original algae is sucked by the suction pumps 26 and 27, and passes through the seawater suction pipes 28 and 29, the flow path switching mechanism 78, and the seawater inflow pipe 47. It flows into the inflow side small water tank 44 of the storage tank 4. Thereafter, the seawater overflows the partition wall 43 and flows from the inflow-side small water tank 44 to the outflow-side large water tank 45, and at that time, the foreign material removal mechanism 62 removes the foreign material. Thereafter, the seawater stored in the outflow side large water tank 45 is sucked by the suction pump 50 and stored again through the seawater suction pipe 51, the seawater cooling device 7, the communication pipe 79, the oxygen supply device 8, and the seawater supply pipe 49. It flows into the inflow side small water tank 44 of the tank 4. Seawater stored in the outflow side large water tank 45 flows into the storage water tank 55 from the seawater outlet 52 through the communication pipe 53 due to water pressure, overflows the partition wall 54 and flows into the overflow water tank 56. It is sucked by the suction pump 58 and flows into the laver storage tanks 2 and 3 through the seawater outflow pipe 59, the flow path switching mechanism 78, and the seawater supply pipes 30 and 31.
このように、上記海水循環システム１では、海苔原藻を貯蔵する海苔貯蔵槽2,3に海水を貯留する海水貯留槽４を接続して、これら海苔貯蔵槽2,3と海水貯留槽４との間で海水を循環させるようにしており、しかも、海水貯留槽４に貯留した海水を循環させるための海水循環流路６を海水貯留槽４に設け、この海水循環流路６の中途部に、循環する海水に酸素を供給するための酸素供給装置８を設けているために、海苔貯蔵槽2,3に海苔原藻を貯蔵しておく期間中に海苔貯蔵槽2,3に海苔原藻とともに貯蔵される海水の酸素濃度が低下するのを未然に防止することができ、これにより、海苔貯蔵槽2,3に貯蔵される海苔原藻の鮮度を向上させることができるとともに、鮮度を向上させた海苔原藻を原料として乾燥海苔を製造することで乾燥海苔の品質を向上させることができる。 Thus, in the seawater circulation system 1, the seaweed storage tanks 4 for storing seawater are connected to the seaweed storage tanks 2 and 3 for storing the seaweed original algae, and the seaweed storage tanks 2 and 3 and the seawater storage tank 4 In addition, the seawater circulation channel 6 for circulating the seawater stored in the seawater storage tank 4 is provided in the seawater storage tank 4, Since the oxygen supply device 8 for supplying oxygen to the circulating seawater is provided, the seaweed algae is stored in the seaweed storage tanks 2 and 3 during the period in which the seaweed storage tanks 2 and 3 are stored. It is possible to prevent the oxygen concentration of the seawater stored with the water from decreasing, thereby improving the freshness of the seaweed algae stored in the seaweed storage tanks 2 and 3 and improving the freshness. The quality of dried seaweed is improved by producing dried seaweed using raw seaweed raw algae It is possible to above.
また、上記海水循環システム１では、海水循環流路６の中途部に、循環する海水を冷却するための海水冷却装置７を設けているために、海苔貯蔵槽2,3に海苔原藻を貯蔵しておく期間中に海苔貯蔵槽2,3に海苔原藻とともに貯蔵される海水の温度が上昇するのを未然に防止することができ、これによっても、海苔貯蔵槽2,3に貯蔵される海苔原藻の鮮度を向上させることができるとともに、鮮度を向上させた海苔原藻を原料として乾燥海苔を製造することで乾燥海苔の品質を向上させることができる。 Further, in the seawater circulation system 1, since the seawater cooling device 7 for cooling the circulating seawater is provided in the middle of the seawater circulation flow path 6, the laver is stored in the laver storage tanks 2 and 3. It is possible to prevent the temperature of the seawater stored in the seaweed storage tanks 2 and 3 from being stored in the seaweed storage tanks 2 and 3 from rising during this period, and this is also stored in the seaweed storage tanks 2 and 3. The freshness of the nori seaweed can be improved, and the quality of the dried nori can be improved by producing the dried nori from the nori seaweed with improved freshness.
特に、上記海水循環システム１では、海水循環流路６に酸素供給装置８や海水冷却装置７を介設し、海水貯留槽４の内部に一定量の海水を貯留しておくとともに、海水貯留槽４に貯留した海水を循環させているために、海水貯留槽４の内部の海水の酸素濃度や温度を良好な状態に保持することができるとともに、海水貯留槽４から海苔貯蔵槽2,3に良好な状態の海水を安定して供給することができる。 In particular, in the seawater circulation system 1, an oxygen supply device 8 and a seawater cooling device 7 are interposed in the seawater circulation channel 6, and a certain amount of seawater is stored in the seawater storage tank 4. Since the seawater stored in 4 is circulated, the oxygen concentration and temperature of the seawater inside the seawater storage tank 4 can be maintained in a good state, and the seawater storage tank 4 can be transferred to the laver storage tanks 2 and 3. It can stably supply seawater in good condition.
また、上記海水循環システム１では、海水冷却装置７を酸素供給装置８よりも上流側の海水循環流路６に設けているために、海水に酸素を供給した後に海水の温度を所定の温度まで低下させてしまうと温度低下に伴って酸素の飽和溶解濃度が低下して一旦溶解した酸素が再び海水から無駄に排出されてしまうことになるのに対して、海水を所定の温度に低下させた後に酸素を供給することになるので、酸素供給装置８から海水に無駄に酸素が供給されてしまうことがなくなり、酸素供給装置８での酸素の供給量を適正化することができる。 In the seawater circulation system 1, since the seawater cooling device 7 is provided in the seawater circulation passage 6 upstream of the oxygen supply device 8, the temperature of the seawater is increased to a predetermined temperature after supplying oxygen to the seawater. When the temperature is lowered, the saturated dissolved concentration of oxygen is lowered as the temperature is lowered, and once dissolved oxygen is exhausted from seawater again, seawater is lowered to a predetermined temperature. Since oxygen is supplied later, oxygen is not supplied to seawater from the oxygen supply device 8, and the oxygen supply amount in the oxygen supply device 8 can be optimized.
また、上記海水循環システム１では、海水貯留槽４に海水に含まれる異物を除去するための異物除去機構62を設けているために、海水の循環によって海苔貯蔵槽2,3の内部の海水に含まれる異物を除去することができ、これによっても、乾燥海苔の品質をより一層向上させることができる。 Further, in the seawater circulation system 1, since the foreign matter removal mechanism 62 for removing foreign matters contained in the seawater is provided in the seawater storage tank 4, the seawater inside the laver storage tanks 2 and 3 is circulated by the seawater circulation. The contained foreign matter can be removed, and this can further improve the quality of the dried nori.
また、上記海水循環システム１では、異物除去機構62の下方に海苔貯蔵槽2,3からの海水流入口46と酸素供給装置８からの海水流入口48とを上下に配設しているために、酸素供給装置８からの海水流入口48より海水貯留槽４に流入する酸素の気泡が海水貯留槽４の内部で上昇するのに伴って海苔貯蔵槽2,3からの海水流入口46より海水貯留槽４に流入する海水に含まれる異物を海水貯留槽４の内部で上昇させることができ、上昇させた異物を海水貯留槽４の上部で異物除去機構62によって良好に除去することができる。 In the seawater circulation system 1, the seawater inlet 46 from the laver storage tanks 2 and 3 and the seawater inlet 48 from the oxygen supply device 8 are arranged below the foreign matter removing mechanism 62 in the vertical direction. As the oxygen bubbles flowing into the seawater storage tank 4 from the seawater inlet 48 from the oxygen supply device 8 rise inside the seawater storage tank 4, the seawater from the seawater inlet 46 from the seaweed storage tanks 2, 3 Foreign matter contained in the seawater flowing into the storage tank 4 can be raised inside the seawater storage tank 4, and the raised foreign matter can be satisfactorily removed by the foreign matter removal mechanism 62 at the upper part of the seawater storage tank 4.
また、上記海水循環システム１では、海苔貯蔵槽2,3の上部と下部とに海水貯留槽４からの海水流入口36,37,38,39を設けているために、海苔貯蔵槽2,3の内部の海水の酸素濃度を全体的に均一に上昇させることができ、或いは、海苔貯蔵槽2,3の内部の海水の温度を全体的に均一に低下させることができる。 In the seawater circulation system 1, since the seawater inlets 36, 37, 38, 39 from the seawater storage tank 4 are provided at the upper and lower parts of the seaweed storage tanks 2, 3, the seaweed storage tanks 2, 3 The oxygen concentration of the seawater inside the seawater can be increased uniformly throughout, or the temperature of the seawater inside the laver storage tanks 2 and 3 can be lowered uniformly throughout.
また、上記海水循環システム１では、海苔貯蔵槽2,3の上部に設けた海水流入口36,37を海水が霧状に吐出されるように形成しているために、海苔貯蔵槽2,3への海水の吐出に伴って大気中の酸素を海水に供給することができ、海苔貯蔵槽2,3の内部の海水の酸素濃度を上昇させることができ、海苔原藻の鮮度向上や乾燥海苔の品質向上を図ることができる。 In the seawater circulation system 1, since the seawater inlets 36 and 37 provided at the upper portions of the laver storage tanks 2 and 3 are formed so that the seawater is discharged in the form of mist, the laver storage tanks 2 and 3 Oxygen in the atmosphere can be supplied to the seawater along with the discharge of seawater to the seawater, the oxygen concentration in the seawater in the laver storage tanks 2 and 3 can be increased, freshness of the seaweed original algae can be improved, and dried seaweed Can improve quality.
また、上記海水循環システム１では、海水貯留槽４に複数の海苔貯蔵槽2,3を流路切換機構78を介して接続しているために、一台の海水貯留槽４を用いて複数の海苔貯蔵槽2,3の内部の海水を循環させることができ、大量の海苔原藻の鮮度向上や乾燥海苔の品質向上を図ることができる。 Further, in the seawater circulation system 1, a plurality of laver storage tanks 2 and 3 are connected to the seawater storage tank 4 via the flow path switching mechanism 78, so that a plurality of seawater storage tanks 4 are used. Seawater inside the laver storage tanks 2 and 3 can be circulated, so that the freshness of a large amount of seaweed original algae and the quality of dried laver can be improved.
