ABSTRACT:
An apparatus for fine-mixing, dispersing, and emulsifying media capable to flow, such as gases or fluids, comprising an injection nozzle for injecting the pre-mixed media and a hollow body with a bore, disposed mirror-inverted and at a small distance thereto, the outlet end of said nozzle and inlet end of said hollow body, seen in the direction of flow, being a part of an annular gap working as pre-emulsifying chamber. For intensifying the mixing and effecting a pre-emulsification, the hollow body with the bore is sharp-edged. The apparatus further comprises a following homogenizing chamber having at its internal walls means for enhancing the turbulence of the mixture.
If no pre-mixed media are used, it is also possible to provide for one or more channels, disposed perpendicularly to the injection nozzle and reaching into said annular gap for injecting a second medium or further media.
The small, sharp-edged annular gap and the means for enhancing the turbulence of the mixture in the homogenizing chamber provide for a very good and stable emulsion needing less energy than known apparatus.
