PURPOSE:To form uniform laver sheets, by adjusting the concentration of a prepared laver stock to make a differential value between the apparent concentration measured by transmitted light of the prepared laver stock and the apparent concentration measured by transmitted light of water after removing the laver in agreement with the set concentration value. CONSTITUTION:The differential value of an apparent concentration measured by a prepared laver stock concentration detection part 15 of the transmitted light type and apparent concentration measured by an apparent concentration detection part 20 of colored water of the transmitted light type and the difference from the set concentration of a concentration adjusting apparatus are used to operate electrically a water supply pump 6 and drainage pump 10. The substantial concentration of the prepared stock fed to a laver sheet forming machine can be always kept at the set concentration regardless of the coloring degree of water. |
