Abstract: Conventional devices for mixing liquids include a container and some form of stirrer for one stage mixing. A two stage mixer for producing a homogeneous emulsion includes a container, a stirrer, and a preliminary mixer in the form of an arcuate plate defining a target above the stirrer. The two liquids are injected into the container through orifices, which are suitably oriented that the liquid streams converge to meet at the target. Thus, preliminary mixing of the liquids occurs at the target, and the liquids fall to the bottom of the container where the mixing process is completed by the stirrer.
