Pneumatic batching/blending system

The in-line pneumatic batching system facilitates simultaneous weigh-batching of major ingredients supplied in bulk bags, manual dumping of preweighed minor ingredients and blending of the material while a subsequent batch is accumulated. Each bulk-bag discharger is mounted on a load cell, 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 desired batch weight has been discharged. System software allows for mid-batch bag changes. Minor ingredients are added at the manual dumping station, after the major ingredients have been discharged. A dilute-phase vacuum conveyor line terminates at a filter receiver, which accumulates the batch before discharging it through a slide gate valve into a ribbon blender, allowing concurrent batching and blending of materials. Other features include FLOW-FLEXER™ bag activators and POP-TOP™ stretching devices. System components are available constructed of carbon steel with an industrial finish, or in stainless steel finished to meet industrial food, dairy or pharmaceutical standards.
