PURPOSE:To control salt concentration of a raw material for laver preparation, by feeding fresh water and sea water to a blender in a ratio to provide a mixed water having a concentration close to a standard value of proper concentration, feeding the fresh water or the sea water depending upon the degree of the concentration of the mixed water. CONSTITUTION:Fresh water is sent from a fresh water tank to a blender for preparing mixed water by the pump P1, and sea water water from a sea water tank to the blender by the pump P2. The pumps P1 and P2 are operated by the drive circuit output signal of a control device for the mixed water to operate by receiving the output of a concentration sensor and a water level sensor, and feed amounts of the sea water and the fresh water, consequently, a feed amount of the mixed water and the concentration of salt are regulated. A large amount of a raw material for laver preparation is fed to a laver manufacturing machine without causing troubles. |
