摘要

PROBLEM TO BE SOLVED: To quantitatively discharge a solid material without causing a bridging phenomenon while maintaining a state in which a solid material is immersed in a liquid material at an appropriate ratio. SOLUTION: A cylindrical body 4 in a vertical posture, a quantitative discharge means 7 which is arranged below the cylindrical body 4 and feeds a solid raw material 6 by a fixed amount, and a water level control means 10 for controlling the water level of a liquid raw material 8 are provided. The solid raw material 6 and the liquid raw material 8 are put into the cylindrical body 4 and are sent to the quantitative discharge means 7 by the dead weight of the solid raw material 6 while controlling the water level of the liquid raw material 8 to be quantitatively discharged. .
