摘要
With regard to cutting materials, such as bread, rye bread and cake, a lot of methods can be applied. This paper studies the method of ultrasonic cutting in food processing. There are four major components in the typical ultrasonic food cutting system. They are the power supply, the transducer, the booster and the cutting tool. We not only focus on cutting in food processing through comparing the principle of ultrasonic cutting with conventional cutting, but also address practical applications of ultrasonic cutting in food processing through the performance of ultrasonic cutting of bread, rye bread and cake. The results show that ultrasonic cutting can be applied to cut thin slice of food, which the conventional cutting cannot do. Moreover, in order to extend practical applications of ultrasonic cutting in food processing, a novel kinematic mechanism is proposed to satisfy motions of ultrasonic cutting equipment.
