Automatic discharging stations for Octabin and Big Bag

For all free-flowing, up to „difficult“ materials

conventional discharge stations problem

Conventional discharging systems for octabins and Big Bags often cause difficulties. The bulk emptying process is often interrupted and leads to production disruptions. The big-bag is sucked in or the material does not flow continuously. Especially at the end of the discharging process conventional discharging systems can't finish the process automaticly untill completely emptied. Often an operator has to guide the suction pipe by hand for a longer period of time in order to fully discharge bulk bags.

bulk discharging with vibration suction head

With our OKTOMAT® discharge stations we use vibrating suction heads. The vibrating suction head reliably loosens crimps in the bulk material. Spacers prevent the film bag from being sucked in. The automatic bag tightening system continuously pulls the big bag upwards. The loosened material flows towards the center and is continuously sucked off. OKTOMAT® emptying stations can empty big bags and octabins completely and reliably without manual intervention.

For all bulk bags with foil inlet or loops

The OKTOMAT® handles easily and effectively the emptying of all common types of Big Bags, octobins, folding boxes, lattice boxes, bulk bags with foil inlet, etc.

  • Big Bag - container with loops
  • Octobin - container with foil inliner
  • Mesh box - container with foil inliner

Bulk material in all variations

OKTOMAT® stations are ideally suited for the majority of applications. They handle the emptying of free-flowing to bridge-forming materials. For even more difficult tasks, the discharge station can be extended with options. Ask our experts to get professional guidance for your project.

History of a success story

OKTOMAT® system discharging station wins out worldwide

HELIOS was granted an EP and a US patent for a suction device based on a patent application in 1995, in which a floating suction head is used for discharging bulk bags from above instead of the usual suction pipe. The foil bag is automatically pulled upwards via tension/clamping device in order to achive a virtually complete discharging.

This fundamental idea, which was progressively developed by adding further process and device features, such as

  • Raising the remaining bulk material of the floor
  • Clamping of the foil bag by means of a tension belt
  • Oscillation of the suction head while discharging
  • Fluidization of the bulk material by compressed air via nozzles at the suction head
  • Clamping and relieving the bulk bag wall while discharging

which also were protected by patent, led to the system OKTOMAT®

Depending on the task, various frame types have proven to be particularly advantageous in practice. 
Since the first presentation at the FAKUMA in 1996, more than 5000 systems have been installed worldwide.
