This company’s Rotary Scalpel technology (photo) can deliver small increments of a wide variety of solid materials with precisions of ±0.5 g. The technology consists of a large inlet area designed for consistent material flow feeding into a rotary feed drum, and a pneumatically controlled “scalpel” that ensures each vane of the feed drum is filled precisely, while the excess is recirculated to the material source. In batching applications, the Rotary Scalpel can be applied as a standalone batch-dribble system, or as a batch-dribble control system to complement a fast-fill batcher. It can also be used as a single-ingredient, loss-in-weight batch system, or as a single-ingredient, gain-in-weight batch process system. — 3i’s Technologies, Vineland, N.J.
