Flexicon combination bulk bag and manual dump batching system

A combination bulk bag and manual dump batching system weighs bulk materials that are discharged from bulk bags or manually dumped from sacks, boxes and other containers and empties the batch into mobile storage bins.

The stainless steel hygienic system consists of a bulk bag unloading frame, two hoppers and two flexible screw conveyors that feed a central gain-in-weight hopper under automated control.

A programmable controller with manual start button activates either of the flexible screw conveyors to load the first ingredient into the central weigh hopper at maximum feed rate. Load cells supporting the hopper transmit weight gain information to the controller, which steps down the feed rate to trickle, prior to reaching the target weight.

A telescoping tube maintains constant downward pressure on the clamp ring and bag spout, elongating the bag as it empties, and bag activators raise and lower the bottom edges of the bag into a ‘V’ shape, directing material into the bag outlet spout.

A removable bag-lifting frame with bag strap hooks and fork tubes allows loading of the lifting frame with bag intact, onto a cradle at the top of the unloader frame posts.

The flexible screw conveyors, using washable polymer tubes, are said to handle a variety of free- and non-free-flowing bulk materials, including products that pack, cake, smear or easily degrade, with no separation of blended products.
