Reverse-lift mixers with CIP and purged controls
The Double Planetary Mixer is available in a reverse-lift design that raises the vessel to the mixing position, rather than lowering the agitator assembly. A reverse lift facilitates improved rigidity and more uniform blade-to-vessel clearances without relying on the floor to be completely level. Four of eleven such reverse-lift model DPM-100 mixers (photo) were recently built for a single end user. Two interchangeable mixing vessels are supplied with each machine to form a semi-continuous mixing operation. Double Planetary Mixers can process both wet (pastes and slurries) and dry (granulations and powder blends) applications, including semi-solids (gels and dough-like materials). The 100-gal mixers feature an elaborate clean-in-place (CIP) system, which includes a total of five ports with rotating spray nozzles directed at the gearbox, agitators and vessel. Each mixer is controlled from a NEMA 4X stainless-steel purged panel (Class I, Div 1, Group D). The entire fleet of eleven machines is explosion-proof. — Charles Ross & Son Co., Hauppauge, N.Y.
