Charles Ross & Son Co. recently announced that its double-planetary mixer is available in a “super sanitary” turnkey configuration, featuring a common stainless steel workbench for both the mixer and matching discharge system. On the sanitary 4-gal double-planetary mixer and discharge system model DPM/DS-4S shown, both interior and exterior stainless steel surfaces are type 316, with a 150-grit (#4) finish and electropolished.

The company reports that the unit’s jacketed mixing vessel and special high-viscosity blades are a dynamic combination for producing thick gels, pastes, putties, and other semi-solids under precise temperatures. 100% sealed gearbox and stirrer shafts reportedly ensure complete cleanability and eliminate cross-contamination between batches. This system is scalable through 1,000-gal production models.
