Multi-agitator mixing systems for specialty applications

| By Mary Page Bailey and Gerald Ondrey

This company has engineered a purpose-built VM-450-gallon VersaMix (photo) that features three independently driven agitators, including a two-wing center-mounted agitator with contoured bottom and Teflon scrapers to efficiently motivate viscous product throughout the mixing zone, a long helical flight agitator to produce better top-to-bottom mixing and a dual-propeller agitator for low shear, high-flow mixing. The tank of the VersaMix is fabricated from durable 304 stainless steel, designed for vacuum operation and internal pressures of up to 50 psi. For efficient discharge, a two-way, flush tank ball valve has been integrated, while a 14-in. manway provides access for ingredient additions and cleaning operations. — Charles Ross & Son Company, Hauppauge, N.Y.
