A new Bulk bag weigh batching system from Flexicon Corp. feeds ingredients into a central weigh hopper using four flexible screw conveyors, and transports pre-weighed batches to a downstream blender using a pneumatic conveying system. The âBFC Seriesâ? bulk bag dischargers feature a cantilevered I-beam with electric hoist and trolley to raise and position bulk bags without the use of a forklift. The units are equipped with Flow-flexer bag activators that raise and lower opposite bottom edges of the bag at timed intervals, loosening compacted materials and promoting material flow into the discharge spout. As the bag lightens, the stroke of the bag activators increases, raising the bottom of the bag into a steep âVâ? shape. Each discharger is equipped with a surge hopper discharging into an enclosed Flexicon flexible screw conveyor. System software allows mid-batch bag changes and automatically compensates for material-in-flight by stopping the conveyor in advance of attaining final batch weights. The controller then activates a rotary airlock valve to discharge the pre-weighed batch into a pneumatic conveyor line terminating at a Flexicon filter receiver positioned above a ribbon blender. System components are available constructed of carbon steel with durable industrial finish, or stainless steel finished to industrial food, dairy or pharmaceutical standards.
