PROBLEM TO BE SOLVED: To provide, a continuous manufacturing method of a granular coloring compsn. of a high pigment content for solving problems of flashing method, by continuous phase conversion among an aq. suspension of the pigment and an oily vehicle, in a flow type stirring unit having stirring blades while forming a vapor phase in the stirring unit. SOLUTION: When an aq. suspension of a pigment and an oily vehicle are continuously supplied into a flow type stirring unit having stirring blades 3 while forming a vapor phase, a granular coloring compsn. is formed by phase conversion of the pigment from water to the oily vehicle by rotating the stirring blades, and the granular coloring compsn. and the water are continuously taken out from the stirring unit. |
