<p>PROBLEM TO BE SOLVED: To provide a fluid mixing device whose size is downsized by reducing a number of main agent supply lines and cleaning liquid injection valves preferably.SOLUTION: A first liquid main agent which has been selected from plural liquid main agent injection valves 14 and is injected into an injection space 24a of an injection body 24, is cleaned by cleaning liquid injected from the other end of the injection body 24 by a cleaning liquid injection valve 50 and discharged from a discharge port 24c. Thereby, unlike conventional state, there is no need for provision of plural cleaning liquid injection valves via plural main agent supply lines connected to a mixing machine 30, and cleaning of the liquid main agent in the plural main agent supply lines are not required. Therefore, by reducing the number of the cleaning liquid injection valves 50 and the main agent supply lines preferably, the fluid mixing device 10 can be downsized.</p> |
