Sanitary bulk bag weigh batch unloader

13 November 2017

This BULK-OUT® Bulk Bag Weigh Batch Unloading System automatically conveys weighed batches and allows rapid sanitising. 

A cantilevered I-beam with electric hoist and trolley positions bags without a forklift.  A SPOUT-LOCK™ clamp ring atop a TELE-TUBE™ telescoping tube connects the clean side of the bag spout to the clean side of the equipment, and maintains constant downward tension on the bag as it empties and elongates, promoting complete discharge.

FLOW-FLEXER™ bag activators increasingly raise opposite bottom edges of the bag as it lightens, ultimately forming a steep V-shape that additionally promotes complete discharge.

A bag dump station with bag shelf allows manual dumping of minor additions.

An integral BAG-VAC™ dust collection system draws airborne dust from manual dumping activities when the hopper lid is open. With lid closed during bulk bag discharging, the system additionally prevents displaced air and dust from entering the plant, and collapses empty bags prior to tie-off, preventing dust generated when empty bags are flattened manually.

A FLEXI-FORCE® lump breaker reduces agglomerates and promotes the continuous flow of material into the charging adapter of the flexible screw conveyor.

Load cells supporting the entire system are linked to a PLC that stops the flexible screw conveyor once the system has lost a pre-set amount of weight.

The flexible screw is the only moving part contacting material, and is driven above the point at which material exits the conveyor, preventing material contact with seals and allowing rapid sanitising in place. The screw can also be removed quickly for sanitising and inspection.

Positioned above the clamp ring is a POWER-CINCHER™ pneumatically-actuated flow control valve that cinches the spout concentrically, allowing re-cinching of partially empty bags for leak-free tie-offs.
