PURPOSE:To make it possible to carry out the mixing at a stable concentration, by using a rotary vane type metering pump at the bottom of a raw material tank, and supplying a constant amount of water to the tank. CONSTITUTION:A laver in a raw material tank 2 is supplied to a metering pump 25 by rotating blades 10 and a screw 8 rotating in the direction reverse to that of the rotating blades 10 on rotation of a motor, and the excess laver is returned to the upper end of a funnel-shaped part 3' by a return pipe 28. The raw laver is sent to a mixing chamber 31 in a fixed quantity by the rotation of vanes 24. A water supply pump is operated by a sensing valve 41 to supply water from a quantitative (metering) water supplying chamber 32 to the mixing chamber 31, mixed with the laver and then fed through a pipe 50 to a laver sheet forming machine. |
