Slit plate mixer

Figure 3.3 Pressure drop versus total volume rate for various slit plate mixer models LH2, LH25, and LH1000 with the configuration of mixing plates (MPs) and aperture plates (APs).

Figure 3.4 Experimentally determined mixing times for various configurations of the slit plate mixer with 50 pm slit width [32].

The mixer-settler (Fig. 6-28) consists of a mixing chamber (mixed vessel, pump, mixing nozzle, static mixer, etc.) and an adjoining separator, which is separated by a slit plate from the mixing chamber. In the mixing chamber, the feed and solvent are intensively mixed and remain in contact for the duration of the mass transfer of the key component. The mixing device has to be operated such that an optimum droplet size is obtained, i. e., a compromise between the small droplets favored for mass transfer and large droplets for small phase separation times. An optimum stirrer revolution speed is found from the minimum of the curve for... 

Channel structures are etched on two plates which are later positioned face-to-face to give the overall fluid structure [140], In the region where the channels overlap, they are separated by the separation plate defined by an etch stop layer. The channel covered by this structured plate was generated by underetching in the <100> direction through slits in the plate. The micro mixer is assembled from a silicon and a glass wafer connected by anodic bonding.
