Abstract:
A microstructure lamellae mixer having at least one mixing chamber and a guide component for supplying fluids to be mixed to the mixing chamber, the guide component being composed of several planar elements which are layered one above the other and which have at least one surface which comprises microchannels running at an angle with respect to the longitudinal axis of the mixer, the microchannels of adjacent elements crossing each other without contact and having outlets into the mixing chamber, and wherein:a) the planar elements comprise foils into which in each case an individual or a system of adjacent microchannels oriented at alternating angles to the mixer longitudinal axis is incorporated, such that when the foils are layered one above the other, an individual or a series of closed microchannels for guiding fluids to be mixed are formed;b) the microchannels have a depth of <1,000 .mu.m, a width b which is at least 10 times the depth and a base wall thickness of <1,000 .mu.m;c) the openings of the microchannels adjoining the mixing chamber lie in line one above the other, the microchannels of adjacent foils diverging towards fluid inlets to the mixer such that the fluids to be mixed can be fed to separate inlets.
