When the respective chemicals are added in steps 1, 21, and 31, the chemicals are mixed in their respective mixers and flow down in accordance with the arrangement order. As a spiral flow path is formed in the mixer, a long flow path can be obtained with a short straight distance, and the mixing process is lengthened, which improves the mixing effect and allows the mixer to be made smaller. . Furthermore, since each spiral groove member is composed of a plurality of threads, the flow path is divided into small areas, which helps improve mixing efficiency. Furthermore, overall mixing is promoted in the mixing chamber 14 provided between the plurality of spiral groove members. Furthermore, since the spiral groove members are axially adjacent and the screw directions of the spiral grooves are reversed, the rotational direction of the fluid is switched to the opposite direction, which causes turbulence and further improves the mixing efficiency. .
