Mixer provides complete particle disintegration in first pass

July 8, 2009
The new inline high shear mixer is the first to combine: high flow rates (up to 500 gpm) without an auxiliary pump, high tip speeds (up to 18,000 fpm), and ultra-high shear rates, all in a single pass, according to the manufacturer. The advantage of the mixer is its ability to disintegrate large particles and droplets in a single pass. By eliminating the need for inline recirculation, the mixer also delivers an important improvement in process control. Unlike recirculation systems, in which passes through the rotor/stator were estimated statistically, the mixer operates with exactly one pass through the rotor/stator − a statistical certainty. With virtually 100-percent particle/droplet disintegration on the first pass, the mixer produces an exceptionally uniform particle/droplet size distribution. An extremely narrow size distribution contributes to superior product stability and texture, faster solubilization, greater efficacy in the case of pharmaceuticals, greater efficiency for catalyzed chemical reactions and higher quality dispersions and emulsion in the food industry.
