  • Method and apparatus for high intensity ultrasonic treatment of baking materials
    Patent number: 9028131
    Abstract: The present invention discloses a high intensity ultrasonic treatment method and apparatus that is used in conjunction with an existing commercial dough or batter mixer to enhance the rheological, aeration and textural properties of the dough or batter. This change in properties is a result of the phenomenon of acoustic cavitation induced in the dough or batter by treatment with high intensity ultrasonic waves. The present invention discloses a mixing bowl (20) of an existing mixer system that is preloaded with dough or batter, the bowl (20) is located at the center of an ultrasonic bath tank (101) filled with a working fluid. The effect of ultra-sonic waves with power levels above 1 kW can be observed over the entire or partial mixing period of the dough or batter. The ultra-sonic waves of the present invention are generated by a plurality of ultrasonic wave generators (104A, 104B) and piezoelectric transducers (1) mounted on a stainless steel tank (101).
