Available from Flexicon Corporation (Australia) , combination bulk bag and manual dump batching systems weigh bulk materials that are discharged from bulk bags and/or manually dumped from sacks, boxes and other containers, and empties the batch into mobile storage bins.
This batching system is hygienic and incorporates two hoppers, a bulk bag unloading frame, and two flexible screw conveyors that feed a central gain-in-weight hopper under automated control.
Bulk bag and manual dump weigh batch systems feature a programmable controller that has a manual start button that 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. Similarly, the controller starts and stops the second conveyor to load the second ingredient into the weigh hopper, and will then activate the slide gate valve of the hopper to discharge the batch into mobile storage bins.
A Spout-Lock clamp ring that forms a high-integrity seal between the clean side of the bag spout and the clean side of the equipment is a feature of the unloader. A Tele-Tube telescoping tube maintains constant downward pressure on the clamp ring and bag spout to facilitate total evacuation of material, elongating the bag as it empties. Meanwhile, the Flow-Flexer bag activators raise and lower bottom edges of the bag into a steep "V" shape, directing material into the bag outlet spout.
A Power-Cincher flow control valve is located immediately above the clamp ring, employing a series of curved, articulated rods that cinch the bag spout concentrically, allowing dust-free retying and removal of partially-empty bags.
These batching systems also feature a removable bag-lifting frame with bag strap hooks and fork tubes, enabling the loading of the lifting frame with bag intact, onto a cradle at the top of the unloader frame posts.
The flexible screw conveyors can manage a wide range of free- and non-free-flowing bulk materials including products that pack, cake, smear or easily degrade, with no separation of blended products.
Material contact surfaces of these batching systems have a stainless steel finish that is hygienic, with the exception of the polymer conveyor tubes that are removable for rapid, thorough wash down.
For clean, safe handling of dusty materials the floor hopper is available with a containment hood including integral dust collection.
