PROBLEM TO BE SOLVED: To provide a dried laver having improved quality.SOLUTION: A system (1) for producing laver includes a water purification device (2) for supplying clear water by purifying raw water, which is connected to a laver producing device (3) for producing a dried laver from raw seaweed using clear water. In the water purification device (2), the water inlet (11) of a water purifier (4) is selectably connected to a raw water supply channel (15) communicated with a raw water supply source (14), a circulating channel (17) communicated with a clear water storage tank (16), and a water inlet-side discharge channel (19) communicated with a drainage (18), while the water outlet (13) of the water purifier (4) is selectably connected to a clear water outflow channel (28) for outflow of clear water from the water purifier (4) to the clear water storage tank (16) and a clear water inflow channel (29) for inflow of clear water from the clear water storage tank (16) to the water purifier (4). A cleaning chemical storage tank (37) is intermittently connected to the clear water inflow channel (29).COPYRIGHT: (C)2014,JPO&INPIT【課題】乾燥海苔の品質を向上させること。【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(3)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、浄水器(4)の入水口(11)に、原水供給源(14)に連通する原水供給流路(15)と浄水貯留タンク(16)に連通する循環流路(17)と排水ドレイン(18)に連通する入水側排水流路(19)とを選択可能に接続する一方、浄水器(4)の出水口(13)に、浄水器(4)から浄水貯留タンク(16)に浄水を流出する浄水流出流路(28)と浄水貯留タンク(16)から浄水器(4)に浄水を流入する浄水流入流路(29)とを選択可能に接続し、浄水流入流路(29)に洗浄薬液貯留タンク(37)を断続可能に接続することにした。【選択図】図1
