Big Bag Discharger
DAP & DRA
Discharge powders and granules from big bags (FIBCs) to feed your production process. Two configurations to suit your requirements: assisted bag lifting to facilitate discharge, or a solution with an integrated hoist for handling and emptying big bags without a forklift.

Tailored to Your Process
Controlled Discharge of Your Bulk Materials
A big bag discharger, also known as a big bag unloading station, empties powders and granules from big bags (FIBCs) to feed your production line. Sofraden Bulk designs and manufactures these stations with a robust welded steel frame, a big bag support and a dust-tight connection to the discharge hopper.
Depending on the material and process, the equipment can incorporate flow assistance devices, weight monitoring, low-level detection or an outlet dosing system. Two equipment configurations are available: the DRA provides assisted lifting of the big bag to facilitate discharge, while the DAP incorporates an electric hoist for handling and emptying the big bag without a forklift.
Two Configurations
DAP vs DRA
Two equipment configurations: the DRA provides assisted lifting of the big bag to facilitate discharge. The DAP incorporates an electric hoist for handling and emptying the big bag without a forklift.
DAP — Hoist-Assisted Big Bag Discharger
Load and empty a big bag without a forklift.
- Monorail equipped with an electric hoist for moving the big bag
- Lifting frame with hooks and a bag support base
- Ideal for flexible material handling and production line feeding
DRA — Assisted-Lift Big Bag Discharger
Assisted lifting of the big bag to facilitate discharge.
- Assisted big bag lifting
- Improves material flow
- A streamlined solution covering essential requirements
| Criterion | DAP | DRA |
|---|---|---|
| Design | Essential features for efficient operation | An all-in-one solution |
| Handling | Forklift-assisted loading | Integrated hoist handling |
| Best Suited For | Optimizing investment costs | Maximizing autonomy and flexibility |
Operating Principle & Components
The system is built around a welded steel frame with a big bag support and a dust-tight connection to the discharge hopper. Depending on the configuration, it includes assisted big bag lifting or a hoist-based handling system.
- Monorail + electric hoist — big bag handling (DAP configuration)
- Lifting frame equipped with attachment hooks
- Support base for the big bag
- Dust-tight connection system for discharge (discharge hopper)
Available Options & Features
Depending on the material and process, the discharger can be equipped with various options: flow assistance devices, weight monitoring, low-level detection or an outlet dosing system.
Flow Assistance
Bag massage system and vibration for poorly flowing materials
Weight Monitoring
Weighing system to monitor discharged quantities
Discharge Hopper with Low-Level Detection
Signals the end of the discharge cycle
Outlet Dosing System
Sector valve, rotary airlock, screw conveyor or microdosing unit
