A Bulk Bag Unloader, also known as a FIBC Discharger, Big bag Discharger, jumbo bag unloading station, is a specialized industrial station designed to safely, cleanly, and efficiently empty large flexible intermediate bulk containers (FIBCs or “big bag”). It automates and contains the entire discharge process. The system securely lifts and clamps the bulk bag, typically using a hoist or forklift, and then employs a controlled, often vibration-assisted, gravity flow to empty powders, Granulat, or pellets through its bottom spout. The discharge is directed into a receiving hopper, process inlet, or connected conveyor below, all within a completely enclosed environment to prevent dust, contamination, and product loss.
Beyond the Unloader: Complete Bulk Material Handling Solutions
While our core bulk Bag Unloader provides the essential first step, we go much further. We design and deliver complete, integrated material handling systems, seamlessly connecting the unloader to your downstream production. Our portfolio includes:
- Flow-Aid & Conditioning Equipment: Lump breakers, Iris Valve, and screeners to ensure consistent material flow.
- Precision Valving & Air-Locks: Rotary valves and slide gates for controlled discharge and pneumatic system isolation.
- Flexible Conveying Systems: Tubular drag (chain disc) conveyors, flexible screw conveyors, and vacuum/pressure conveying systems for versatile transport.
Downstream Integration: Complete system engineering for connection to mixers, blenders, weigh hoppers, bagging stations, and process vessels.
We don’t just sell a machine; we engineer a reliable, dust-free, and automated material flow for your entire plant. Let us design your solution.
Key Components
Botek’s bulk bag unloader is a modular system built for flexible, dust‑free discharge. Here’s what it includes and why each part matters:
- Heavy‑Duty Frame – Provides structural support and stability for safe operation.
- Lifting Device (Manual/Electric Hoist) – Raises and positions the bulk bag for controlled gravity discharge.
- Bag Clamping & Sealing System – Secures the bag spout and seals the connection to prevent dust escape.
- Bag Massaging/Pounding System: Breaks up compacted material, eliminates bridging, and ensures complete discharge.
- Discharge Hopper with Flow‑Aid Options – Guides material out; optional vibrators or agitators prevent bridging and ensure complete emptying.
- Dust‑Control Port / Integrated Filter – Connects to your plant dust collection or includes a self‑contained filter for clean operation.
- Integrated Control Panel with HMI Touchscreen: Enables automated operation, parameter setting, and system monitoring.

Bulk Material Handling System
Bulk Bag Unloader for Multiple Process Applications
Integrated Unloading & Screening
Removing oversize particles and foreign materials directly at the discharge point. Protects downstream equipment and guarantees a uniform, high-quality flow for your production line.
Discharge and Conveying Line
Automate your material transfer with a fully sealed system. Bulk Bag Unloader feeds directly into a vacuum conveyor, enabling gentle, long-distance transport of powders to multiple destinations.
Flexible, Forklift-Accessible Unloading
Designed for maximum flexibility and ease of use. Our forklift-accessible unloader station allows for quick and safe placement of bulk bags directly from a forklift.

FAQS
Botek Vibrating Spiral Elevator is a vertical conveying system that uses controlled vibration to smoothly lift bulk materials (powders, Granulat, flakes, etc.) along a spiral trough. The machine’s gentle vibratory motion ensures material flow without degradation, making it ideal for fragile or abrasive products. It operates without internal moving parts like belts or chains, reducing maintenance and contamination risks.
Botek spiral elevators are suitable for a wide range of dry bulk solids, including:
Powders: Mehl, cocoa, Gewürze, cement additives, Arzneimittel.
Granulat: plastic pellets, grains, Düngemittel, coffee beans.
Fragile materials: chips, flakes, breakfast cereals.
Abrasive materials: sand, Mineralien, metal parts.
The enclosed design and smooth vibratory motion prevent dust generation and product breakage.
Our standard models offer lifting heights from 1 Zu 12 meters, with capacities ranging from 100 kg/h to 20 tons/h, depending on material characteristics and spiral diameter. Custom heights and capacities are available upon request. Detailed technical specifications can be provided based on your material test or application data.
Botek vibratory spiral elevators can handle materials up to 1000°C with optional heat-resistant coatings or cooling jackets. For cold or cryogenic applications, insulated designs are available. Please consult our engineers for specific temperature requirements.
