Method and statistical micromixer for mixing at least two liquids
First Claim
1. Procedure for mixing at least two fluids comprising the following steps:
- a multitude of separate fluid currents of the two fluids, each of a width in the range of 1 μ
m to 1 mm and a depth in the range of 10 μ
m to 10 mm, are brought together and alternately adjacent fluid lamellae of the two fluids are generated;
the combined fluid currents are carried away and a focused total fluid current is generated;
the focused total fluid current is fed as fluid jet into an expansion chamber with a larger cross section than the focused total fluid current perpendicular to the flow direction of the focused total fluid current;
the resulting mixture is drawn off.

Abstract
The invention relates to a procedure and a micromixer for mixing at least two fluids. The aim of the invention is to reduce the mixing time of the micromixer compared to micromixers known to the art while maintaining high mixing quality and small structural dimensions. The inventive procedure is characterized by the following steps: a plurality of separated fluid currents of both fluids are brought together and alternately adjacent fluid lamellae of both fluids are formed: the combined fluid currents are carried away and a focused total fluid current is formed; the focused total fluid current is fed as fluid jet into an expansion chamber; and the resulting mixture is drawn off. The micromixer comprises a plurality of alternately adjacent fluid channels (2, 3) which open into an inlet chamber (4). A focusing channel (5) is in fluid connection with said inlet chamber and opens into an expansion chamber (6). The inventive procedure and micromixer are especially advantageous in that they are suitable for the production of emulsions and dispersions.

a multitude of alternately adjacent fluid channels (2, 3) of a width in the range of 1 μ - m to 1 mm and a depth in the range of 10 μ
m to 10 mm for separately supplying the fluids as fluid currents;
an inlet chamber (4) into which the fluid channels enter;
a focusing channel (5) fluidly connected to the inlet chamber (4) for carrying away the fluid currents combined in the inlet chamber (4) and generating a focused total fluid current;
an expansion chamber (6), into which the focusing channel (5) enters and into which the focused total fluid current runs as fluid jet, with a larger cross section than the focusing channel (4) perpendicular to the axis of the focusing channel (4), and at least one outlet channel (7) fluidly connected to the expansion chamber (6) for drawing off the resulting mixture. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
