Abstract:
A dispersing method comprising the steps of: storing a dispersing medium and a liquid containing a material to be treated in a tank; drawing the dispersing medium and the liquid containing the material to be treated into a dispersing chamber by suction; moving the dispersing medium within the dispersing chamber to disperse the material to be treated in the liquid; discharging only the liquid containing the dispersed material from a discharge outlet of the dispersing chamber while separating the dispersing medium from the liquid containing the dispersed material; circulating the liquid containing the dispersed material to the tank; removing the dispersed material from the tank; feeding a cleaning liquid into the tank and drawing the cleaning liquid into the dispersing chamber by suction; and cleaning the tank and the dispersing chamber by permitting the dispersing medium to flow out of the dispersing chamber through the discharge outlet and to circulate together with the cleaning liquid through the tank and the dispersing chamber.
