METHOD OF SIMULTANEOUS ULTRASONIC CAVITATION PROCESSING OF LIQUID MEDIUM VOLUMES Russian patent published in 2013 - IPC B01F3/00 B01F11/02 

FIELD: chemistry.

SUBSTANCE: invention relates to field of cavitation processing of liquid media, where specific content of water or other liquid phase exceeds 30-35% of total weight. Method of simultaneous ultrasonic cavitation processing of liquid medium volumes includes their placement in working liquid in rectangular bath, with material of volumes with liquid media having specific acoustic resistance, equal or close to specific acoustic resistance of working liquid. In working liquid created is standing acoustic wave from all walls and bottom of bath, made in form of resilient membranes, which have their own resonance frequency, equal to first harmonic, with opposite walls of rectangular bath having equal frequencies of first harmonic, and bath length a and width b are selected multiple to one fourth of wavelength, excited in working liquid by side walls of bath: a=(k/4)*(c/fi), b=(k/4)*(c/fi), where c is velocity of sound in working liquid, m/s; f_i are frequencies of first harmonics of side walls of bath, Hz; k=2,4… is integer number, height of working liquid level h is selected multiple to one fourth of wavelength, which is excited by bath bottom, with frequencies f_i of oscillations being multiple to each other with coefficient k.

EFFECT: method makes it possible to effectively process several different or similar compositions of liquid media simultaneously and can be applied for preparation of individual creams with submicron dimension of disperse phase.
