Abstract
A defoaming apparatus (22) defoams a foamable product that is dispersed into a container such as a TETRA REX gable-top carton (80). The defoaming apparatus (22) creates a sonic shock wave (110) that destroys most if not all of the bubbles of the foamable product. The defoaming apparatus (22) has a body (100) that defines a recessed cavity (102). A pair of electrodes (106, 108) is located within the recessed cavity (102). The opening to the cavity (102) can include a radio frequency filter (114) covering to absorb radio waves created from the sonic shock wave (110). The defoaming apparatus (22) is preferably disposed immediately after the filling of the container (80).
