METHOD AND DEVICE FOR MANUFACTURING HOT DOGS USING HIGH POWER ULTRASOUND

摘要

An semi-solid mixture, such as a particule meat mixture, is brought into contact with a vibrating surface, ultrasonic tools (108 and 110), whereby energy is transported across the surface (108, 110) into the mixture. The vibration is generally contemplated to be in the ultrasonic frequency range, and the energy injection is contemplated to be sufficient to cause local physical and chemical changes in mixtures susceptible to such changes, and generally to cause changes in the direction of increase tensile strength and resistance to flow. In general a skin is formed on the mixture, and with greater processing efficiency then if such skin were formed by purely thermal means.
