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.

Abstract: A Sonotrode for generating an ultrasonic field in industrial production processes such as chemical, food, petroleum, pharmaceutical, beverage or mining-related processes for reducing and eliminating foaming of liquid products has a compact one-piece form, wherein the sonotrode is provided with a main body part having a connector for connection with a high frequency generator and having a front face from which the ultrasonic field is directed to the desired spot or area of the product to be de-foamed, wherein the main body part has the shape of a compact block element and in that the front face is concave in shape in relation to a product surface such that the ultrasonic field is focused and directed to a specific area of a product foam to be treated in a concentrated form compared to a non-focused ultrasound.

Abstract: The present invention relates to a method of cleaning a surface by applying highly propagating ultrasonic energy to said surface, the method comprises immersing at least a portion of the surface into a fluid, wherein said fluid is in contact with an highly propagating ultrasonic energy emitting assembly; and emitting highly propagating ultrasonic energy from the assembly into the fluid to generate cavitation at the surface thereby cleaning said surface.

Abstract: The present invention describes a method and apparatus for aqueous extraction of chemical compounds from solid material in which the solid material is entrained in an extraction liquid phase that flowed around immersed sonotrodes emitting radial or focused high energy ultrasonic waves. A significant increase in extracted material and decreases in extraction time is observed.
