<p>The invention concerns a foam generator conventionally consisting of a hollow stator 1 with a coaxial internal rotor 2 together forming an annular mixing chamber. Both stator and rotor being provided with alternate rings of polygonal pins 4, 3 reaching within the mixing chamber, each pin having at least two ribs 11 creating a vortex trail during generation.
<??>The rate of occupancy of the pins 4,3 is such that within a cross-sectional range for the mixing chamber between 40 - 90 cm<2>, the quotient:
total vortex line length
volume of mixing chamber
amounts at least to 1,5 and preferably to between 2,4 and 3,0.</p> |
