Ross has introduced a new Multi-Shaft Mixer equipped with a helical ribbon agitator, which is designed for excellent top-to-bottom mixing of viscous pastes, gels and dense suspensions. Two other agitators – a sawtooth blade and a three-wing anchor – deliver high-speed dispersion and very thorough product turnover. This Multi-Shaft Mixer is extremely versatile in adapting to multiple applications, fine-tuning shear intensity, and heating/cooling to accurate levels.

Pictured is a 150-gallon Ross Multi-Shaft Mixer designed for full vacuum operation up to 29.5”Hg. This mixer is also rated for 3 psi internal pressure for inert gas blanketing and for accelerating product discharge through an automated 3” flush tank ball valve. Hinged Teflon scrapers mounted to the anchor agitator are contoured to match the vessel sidewall and dished-shape bottom. A custom mixer cover includes sight/charge ports, tri-clamp connections for liquid and powder raw materials, a hinged manway, tank light, thermoprobe, rotary spray balls and rupture disc. The 100-psig jacket around the mix vessel features mineral wool insulation and stainless steel sheathing.

Installed under the mixer is a custom pumping system for transferring finished product and supplying CIP solution during the cleaning cycle. The agitators, product and CIP pumps, automated valves, load cells, thermoprobe, tank light and vacuum pump are all controlled and viewed from a Ross SysCon Recipe Control Panel with 15” color touchscreen.
