METHOD OF MIXING HIGH-VISCOSITY FLUIDS Russian patent published in 2013 - IPC B01F3/10 

FIELD: process engineering.

SUBSTANCE: invention relates to chemical, pharmaceutical, food industries, etc, particularly, to mixing of fluids. Fluids are fed into vessel composed of constant-size clearance between walls of coaxial identical-shape vessels, spherical or cylindrical, unless it is completely filled. Said vessels are revolved by external drive toward each other at rpm corresponding to occurrence of turbulence. Fluids are mixed to remove finished mix. Ratio between radii of inner and outer vessels makes 0.44-0.67 while outer vessel rpm f_out is modulated in time by sine relationship at rpm not exceeding 3% of f_out with preservation of permanent values, other than zero, of averaged magnitudes.

EFFECT: higher efficiency of mixing.
