The Ross FDA-3500 dual shaft mixer is powerful enough to batch dispersions, suspensions, and emulsions with viscosities up to several hundred thousand centipoise. The FDA-approved mixer has a maximum working capacity of 3,500 gal, a two-zone stainless-steel dimpled jacket for heating/cooling, a 4-in. pneumatic discharge valve, and an explosion-proof load cell system rated for up to 20,000 lb.
The multi-agitator system is equipped with independently controlled drives and is highly efficient at producing good turnover and imparting shear to a viscous batch. Powered by a 300 hp TEFC inverter duty motor, the high-speed disperser runs at tip speeds up to 5,000 ft per min, inducing high shear forces, while the 60 hp three-wing helical agitator feeds product toward the disperser blade and ensures the mixture is constantly in motion. Teflon scrapers on the anchor wipe materials from the vessel wall, enhancing heat transfer from the jacket.
