<p>A method for preparing emulsions consisting in feeding the steam at a speed of 500-800 m/sec, injecting into the steam liquid components to be emulgated and transporting the two-phase steam-liquid mixture at a supersonic speed. A device for implementing the method comprises a cylindrical casing (1), an aerosol chamber (2), a steam nozzle (4), a mixing chamber (9), the steam nozzle being executed as a Laval nozzle and mounted with the possibility of axial movement, so that an injection zone (5) is created between the end-face of the steam nozzle (4) and the internal surface of the aerosol chamber (2), whereas the mixing chamber (9) has a convergent section (10) facing the Laval nozzle and merging into a cylindrical section (11), behind which is located the divergent section (12).</p> |
