PROBLEM TO BE SOLVED: To provide an effervescent beverage foaming device capable of generating fine creamy and stable foam in a very short time.SOLUTION: An effervescent beverage foaming device used for foaming an effervescent beverage poured into a vessel comprises: a shaft portion an ultrasonic oscillation portion which is continuous with one axial end of the shaft portion and provided with an ultrasonic oscillator and a control portion which controls the driving of the ultrasonic oscillator to oscillate ultrasonic wave from the ultrasonic oscillator at a predetermined frequency. The control portion controls the driving of the ultrasonic oscillator so that the ultrasonic wave is oscillated from the ultrasonic oscillator during a predetermined number of cycles and so that the ultrasonic wave is not oscillated from the ultrasonic oscillator during a predetermined number of cycles thereafter.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】きめ細かくクリーミーであって、消失し難い泡を極めて短時間で発生させることのできる発泡性飲料泡立て装置を提供する。【解決手段】容器に注がれた発泡性飲料を泡立てるために用いられる発泡性飲料泡立て装置は、シャフト部と、シャフト部の軸方向一端部に連続し、超音波振動子が設けられてなる超音波発振部と、超音波振動子から所定の周波数で超音波を発振させるために当該超音波振動子の駆動を制御する制御部とを備え、制御部は、所定のサイクル数の間は超音波振動子から超音波を発振させ、その後の所定のサイクル数の間は超音波振動子から超音波を発振させないように超音波振動子の駆動を制御する。【選択図】図1
