  • Density modification
    Patent number: 9005686
    Abstract: The present invention relates to a method for modifying the density of a flowable material in need thereof comprising applying highly propagating ultrasonic energy at frequency of between about 16 kHz to about 40 kHz to the material wherein the highly propagating ultrasonic energy is uniformly distributed throughout the material thereby modifying the density of the material.
    Type: Grant
    Filed: April 8, 2010
    Date of Patent: April 14, 2015
    Assignee: Cavitus Pty Ltd
    Inventors: Darren Bates, Warwick Bagnall

  • VISCOSITY REDUCTION
    Publication number: 20110278153
    Abstract: The present invention relates to a method for reducing the viscosity of a product by applying highly propagating ultrasonic energy to said product, the method comprising contacting at least a portion of said product with an highly propagating ultrasonic energy emitting assembly; and emitting highly propagating ultrasonic energy from the assembly into the product thereby reducing the viscosity of the product.

  • Method of treatment of vegetable matter with ultrasonic energy
    Publication number: 20060110503
    Abstract: A method for modifying the viscosity of pureed vegetable matter, said method including the step of applying relatively low-frequency ultrasonic energy (having a frequency in the range from about 16 kHz to 100 kHz) to said puree via a sonotrode in a manner such that cavitation of a water fraction in said puree is induced, and the cellular structure and cell wall material of the vegetable matter are degraded, thereby to increase the viscosity of said puree.
