ABSTRACT:
A foam producing apparatus has a first mixing chamber with an inner subchamber connected to a supply of gas at a first pressure and an outer subchamber connected to a supply of a foamable liquid at a second pressure higher than the first pressure. A plurality of orifices connect the outer subchamber to the inner subchamber. The foamable liquid is forced from the outer subchamber into the inner subchamber through the orifices and is atomized to form droplets carried by the gas to an outlet. A second mixing chamber is connected to the outlet of the first mixing chamber and is filled with an agitating medium so that droplets propelled through the second mixing chamber are violently agitated to produce the desired foam.
