An in-line pneumatic batching system from Flexicon allows simultaneous weigh batching of major ingredients supplied in bulk bags, manual dumping of pre-weighed minor ingredients and blending of the material while a subsequent batch is accumulated. Each of the bulk bag dischargers is mounted on load cells, allowing loss-of-weight batching from either or both bulk bags. A system controller starts and stops each discharger's rotary airlock valve to weigh ingredients, first at high feed rate for rapid filling, then at dribble feed rate, stopping material flow once the accurate batch weight has been discharged. System software allows mid-batch bag changes.
