< Topic >Removing the impurity which is included in the raw water which is used for the production of the dry laver satisfactorily, as it improves the quality of the dry laver, prevent the breakdown of the laver production device. SolutionsWith this invention, the clean water central processing unit which supplies the clean water which purifies the raw water jointing (2) to the laver production device (3), supplying oxygen to the raw water, after making the impurity oxidize which is contained in the raw water, it cleaned water the central processing unit (2), to percolate the impurity with the water purifier (4) the laver manufacturing system in order with the laver production device (2) to produce the dry laver from the laver origin alga in (1) making use of the clean water. Especially, with this invention, supplying the ozone gas to the raw water, after making the impurity oxidize, it exhausted, after that, had decided to percolate the impurity with the water purifier (4). < Choice figure >Drawing 1【課題】乾燥海苔の製造に用いる原水に含まれる不純物を良好に除去して、乾燥海苔の品質を向上させるとともに、海苔製造装置の故障を防止すること。【解決手段】本発明では、原水を浄化した浄水を供給する浄水処理装置(2)を海苔製造装置(3)に接続して、浄水を用いて海苔製造装置(2)で海苔原藻から乾燥海苔を製造するための海苔製造システム(1)において、浄水処理装置(2)は、原水に酸素を供給して原水に含有される不純物を酸化させた後に、浄水器(4)で不純物を濾過することにした。特に、本発明では、原水にオゾンガスを供給して不純物を酸化させた後に脱気し、その後、浄水器(4)で不純物を濾過することにした。【選択図】図1
