Method and assembly for pasteurizing and homogenizing low viscosity liquids

摘要

A method and assembly for pasteurizing and homogenizing low-viscosity liquids, the method including the steps of flowing the liquid through a tube comprising a transducer for converting electrical energy to acoustic energy, and providing electrical power to the transducer to generate ultrasound and to transmit the ultrasound through the liquid in the tube to induce acoustic cavitation in the liquid in the tube, wherein the cavitation so induced operates to inactivate microorganisms in the liquid and to reduce the size of fat globules in the liquid to a point at which the globules refrain from coalescing and rising to the surface of the liquid during the useful storage life of the liquid.
