ABSTRACT:
A device for producing a liquid emulsion of a hydrophobic and hydrophilic liquid is described. The emulsion consists of at least one hydrophobic liquid phase and at least one hydrophilic liquid phase, one of said phases being a disperse phase of the emulsion, which has a stable colloidal state with a particle size of the disperse phase of 1,000 nm or less, preferably a particle size in the range of 100 to 500 nm. The device includes a mixing apparatus (1) comprising a mixing chamber of a rotational symmetrical shape in a hollow element (14) with a plurality of tangential inlet openings (15) opening into a first chamber portion connected to a second chamber portion having a tapering section in flow direction and an axial outlet being coaxial with the axis of the mixing chamber, the first chamber portion has a rotational paraboloid form and second chamber portion has a rotational inverse hyperboloid form, said axial outlet being a cylindrical duct portion (18), the parabolic wall (14) of said first chmber portion defining a focal line falling in the axis of rotation, said inlet openings (15) being arranged at a wide cross-section of the first chamber portion which is connected to the second chamber portion at the widest cross-section thereof, and the sum of the cross-sections of the inlet openings (15) substantially corresponds to the cross-section of said duct portion (18).
