The Iso-Flo family of stainless steel vibratory conveyors has new features, including frame design, patent-pending drive arrangement and screen clamp to maximize machine efficiency, enhance sanitation and improve ergonomics on production lines. The traditional tubular frame is replaced with a shaped plate frame. Independent, frame-mounted drives and spring arm assemblies distribute energy equally to all parts of the conveyor bed in a controlled natural-frequency operation, according to the company.
