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.

An emulsifying or mixing apparatus comprising, a housing, an injection nozzle positioned at one portion of the housing for injecting a continuous phase media, a hollow body positioned opposite to said injection nozzle in said housing and separated from said injection nozzle by an annular gap, said hollow body having a sharp-edged inlet end, an outlet end and being disposed in a mirror-inverted manner, at least one injection channel for injecting a discontinous phase media into the annular gap, whereby the continuous phase media is injected into the annular gap by said nozzle and the discontinous phase media is injected into the annular gap through said injection channel, both media entering said hollow body through the sharp-edged inlet end and passing out of said hollow body through the outlet end, and a homogenizer adjoining said hollow body in said housing, said homogenizer having an inlet adjoining the outlet end of said hollow body for receiving the media from said hollow body, the media having a direction of flow in said homogenizer, an outlet for passing the media, and a homogenizing chamber having a geometrical shape for causing turbulence in the media through internal walls adapted to cause turbulence in the media, the internal walls comprising aplurality of plates, each plate having at least one bore with at least one edge, each edge of each bore forming an angle with respect to the direction of flow of the media.
