Abstract (en)
[origin: EP1312409A1] A mixer assembly comprises a longitudinal tube incorporating an array of baffle plates, with alternating profiles generating a laminar mixing sequence for two ingredients (A, B). The tubular mixer baffles have a hybrid structure, with one group of guide vanes (Q) alternating with another (X) different set of vanes. <??>The assembly mixes substances which are not easily miscible. The first baffle section creates a laminar flow in the first substance. The second different section sets up a laminar flow in the second substance. Each substance transversely intersects the other substance's flow-path. One section has a structure (Q) comprising a group of four strands with mixing compartments (18) extending between two ends (14a, 14b), and longitudinally transposed (11) with respect to adjacent compartments. This structure (Q) generally dominates the mixing pipe. The second structure (X) (8) has cross-pieces (81, 82) which are inclined with respect to the longitudinal plane. The structures (Q, X) are made of injection molded plastic.
