Product Overview
Learn everything you need to know about Flexicon Bulk Bag Dischargers.
BULK-OUT® Bulk Bag Dischargers
Klausen Process Machinery BULK-OUT® Bulk Bag Dischargers – also known as FIBC, Big Bag, or Jumbo Bag unloaders are available in a wide range of frame configurations to suit various operational needs. Each model can be customized with innovative accessories and integrated flow-promotion devices to ensure efficient, dust-free, and reliable material discharge.
Engineered for strength and long-term durability, Flexicon’s discharger frames provide stable support for bulk bags throughout the unloading process. Available in rugged carbon steel with industrial-grade finishes or corrosion-resistant stainless steel, these frames are built to meet the demands of industrial, food, dairy, and pharmaceutical applications.
FLOW PROMOTION
BAG SPOUT INTERFACE
SPOUT-LOCK® clamp ring eliminates dust during untying, discharge, bag collapse and removal
The SPOUT-LOCK® clamp ring forms a sealed, high-integrity connection between the clean side of the bag outlet spout and the TELE-TUBE® telescoping tube, preventing contamination and dust release during untying, discharge, bag collapse, and removal. This secure interface allows safe drawstring release for dust-free material flow into the hopper, while quick-release handles ensure fast, tool-free spout connections. By maintaining a sealed system, SPOUT-LOCK® often eliminates the need for flow control valves, except when retying partially emptied bags.
TELE-TUBE® telescoping tube prevents dead spots and promotes flow
The TELE-TUBE® telescoping tube raises the SPOUT-LOCK® clamp ring for connection to the bag spout, then lowers to maintain continuous downward tension. As a result, the spout is kept taut at all times, preventing excess spout material from bulging outward (creating dead pockets) or falling inward (creating flow restrictions). Works in conjunction with the SPOUT-LOCK® clamp ring and FLOW-FLEXER® bag activators to promote material flow and total evacuation. Available USDA accepted.
Leak-proof retying of spouts with POWER-CINCHER® flow control valve
Unlike opposing bars that pinch the spout of partially empty bags from two sides, the POWER-CINCHER® pneumatically-actuated flow control valve contains a series of curved, articulated stainless steel rods that cinch the spout concentrically on a horizontal axis for easy tie-offs, and vertically in a tight zigzag pattern to prevent leakage of even the finest powders. It also resists jamming, breaking and leaking, and allows full-open discharge from bag spouts of all popular diameters. Available USDA accepted.
Conventional Iris Valves Also Available
When a sealed connection isn’t necessary, iris valves offer a reliable solution. The bag outlet spout is pulled through the valve, which is then closed around the spout to prevent premature material flow during untying of the bag. Once the spout is untied and the access door is closed, the valve is gradually opened to initiate controlled material flow into the hopper.

Total Dust Containment
Klausen Process Machinery bulk bag dischargers feature a sealed system that maintains dust-free
operation at every stage of the discharge cycle. From untying bag spouts to
retying partially emptied bags and collapsing empty bags, the system ensures
clean, contained handling.
High-integrity connection between bag outlet spout and discharger.
The SPOUT-LOCK® clamp ring forms a secure, dust-tight seal between the clean side of the bag spout and the clean side of the TELE-TUBE® telescoping tube. Once connected, the bag’s drawstring can be released, allowing material to flow freely into the hopper—quickly and without dust
BAG-VAC® dust collector collapses empty bags prior to tie-off.
The sealed connection can be vented through a filter sock, a central dust collection system, or Flexicon’s optional BAG-VAC® dust collector. Activating the BAG-VAC® creates negative pressure within the sealed system, collapsing empty bags before tie-off and eliminating dust typically released during manual flattening. It also vacuums particles trapped in spout creases during disconnect, removing the need for awkward access ports.

Product benefits
Learn everything you need to know about Flexicon Bulk Bag Dischargers.
Total Dust Containment
Klausen Process Machinery bulk bag dischargers deliver total dust containment with these precision-engineered features:
- POWER-CINCHER® Flow Control Valve: Cinches bag spout concentrically with stainless steel rods, preventing dust leakage and enabling dust-free retying of partially empty bags.
- TELE-TUBE® Telescoping Tube: Maintains a dust-tight seal with constant tension on the bag spout, ensuring complete, dust-free material discharge.
- SPOUT-LOCK® Clamp Ring: Creates a high-integrity, dust-tight seal between the bag spout and TELE-TUBE® telescoping tube, eliminating dust during connection and discharge.
- BAG-VAC® Dust Collector: Collapses empty bags under negative pressure, vacuuming residual particles for a dust-free disconnection process.
- Sanitary Design for Hygienic Performance: Klausen Process Machinery sanitary bulk bag dischargers feature stainless steel construction, quick-release clamps, and removable components designed for easy cleaning, with USDA-accepted and FDA-compliant materials ensuring compliance with stringent hygiene standards in food, dairy, and pharmaceutical applications.
- Reduced Material Cost per Unit
Using a bulk bag discharger lowers the cost per unit of bulk material by enabling the purchase and use of larger quantities in a single bag, which is typically more economical than buying multiple smaller bags. - Automation and Reduction of Manual Labor
Using bulk bags in industrial processes significantly reduces labor costs and improves efficiency compared to manually dumped bags, as they allow for faster, automated handling and transport of large material volumes. - Minimized Residual Powder Waste
A bulk bag discharger reduces material waste by minimizing the amount of residual powder left in a single bulk bag compared to the cumulative residue in multiple smaller bags - Decrease Packaging Material Waste
A bulk bag discharger decreases the need for packaging materials by using fewer bags overall, with the added advantage that bulk bags can be reused in some circumstances, further reducing the demand for new paper or plastic bags.
- Flow Promotion
Flexicon bulk bag dischargers are equipped with advanced flow promotion technologies, including FLOW-FLEXER® bag activators, POP-TOP™ extension devices, and TELE-TUBE® telescoping tubes. These purpose-engineered features ensure smooth, reliable material flow from bulk bags, delivering consistent discharge and seamless downstream operations. - Effortless Retying of Partially Empty Bags
The POWER-CINCHER® flow control valve cinches the bag spout concentrically, allowing leak-free retying of partially empty bags with ease and precision. - Streamlined Bag Loading
Featuring Z-CLIP™ strap holders for quick and secure strap insertion, an integrated hoist and trolley for forklift-free positioning (model BFC), wide fork-truck receiving pockets for easy loading (model BFF), and a TELE-TUBE® telescoping tube that provides convenient access to bulk bag spout tie points, ensuring a seamless and efficient loading process.
