Patent ID: 8641264

Claim:
A method for producing paint, the method comprising: charging into a tank a liquid paint material to be mixed and dispersed; sucking part of the paint material in the tank with a pump; and, with the pump, passing the sucked paint material through a flow path reduction area and then discharging the sucked paint material from a discharge outlet that is submerged in the remaining part of the paint material in the tank, thereby performing agitation, mixing, and dispersion, wherein the flow path reduction area is configured to accelerate the flow rate by narrowing the flow path, the sucked paint material is supplied to a fixed higher end of the flow path reduction area, discharged from a fixed lower end of the flow path reduction area, and then discharged from the discharge outlet, the flow path reduction area comprises nozzle plates that each have a plurality of nozzle holes and are lined up from the upstream side to the downstream side of a paint material flow; and nozzle holes of adjacent nozzle plates are formed so that a plurality of nozzle holes on the downstream side partially face one nozzle hole on the upstream side.
