<p>PROBLEM TO BE SOLVED: To form a gas-liquid mixed flow and turn foams contained therein into fine foams. SOLUTION: A gas introduction tube 4 is provided on an inflow tube 1a of a container 1, and the opening inner diameter d2 on the side of the gas introduction tube 4 is formed larger than the inner diameter d1 of a flow inlet 2, and pressure in an opening of the gas introduction tube 4 is made negative to suck in external gas to form a gas-liquid mixed flow and introduce the same into the container. At least one rotor 9 of a disk type with a number of fine holes 9a is set almost vertically to the flow of a fluid in the container 1 and rotated by a driving mechanism 5. When foams contained in the gas-liquid mixed flow are passed through the holes 9a of the fluid, the foams are cut at non-hole sections 9b and the small size foams are turned into fine foams forming the gas-liquid mixed flow and flowed out of an outflow opening 3.</p> |
