Reverse-lift Double Planetary Mixers with elaborate CIP and purged controls

The ROSS Double Planetary Mixer is available in a reverse-lift design which 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. Pictured below are four of eleven such reverse-lift model DPM-100 mixers 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-gallon mixers feature an elaborate CIP system, which includes a total of five ports with rotating spray nozzles directed at the gearbox, agitators and vessel. The spray balls are piped to a central cleaning system manifold for single-point hook-up. Raw material feeding equipment may be hard-piped to the vacuum hood—another advantage unique to the reverse-lift design.

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.
