Bag Opening Machine 400 to 800 Bags Per Hour Automatic Bag Emptying System for Granular Materials

The Bag Opening Machine is a fully automatic layer-by-layer bag emptying system designed for continuous handling of bagged granular materials. It automatically performs pallet feeding, bag separation, bag opening, material discharge, screening, dust collection, and empty bag recycling in one integrated process.

Designed for processing soybeans, wheat, coffee beans, plastic pellets, resin granules, fertilizers, pet food, and other free-flowing materials, the system delivers stable production capacities ranging from 400 to 800 bags per hour. Compared with manual bag opening, it significantly improves production efficiency while reducing labor costs, dust emissions, and material loss.

The machine adopts a precision cutting mechanism together with an intelligent PLC control system to ensure accurate bag opening and maximum material recovery. Carbon steel, SUS304, and SUS316 stainless steel versions are available, with food-grade contact parts for hygienic applications. The equipment can be seamlessly integrated with conveying systems, storage silos, screening equipment, weighing systems, mixers, and downstream production lines, making it an ideal automated feeding solution for modern factories.

As production capacity continues to increase, manual bag opening has become one of the least efficient processes in many factories.

Common challenges include:

• High labor costs caused by repetitive manual unloading
• Low production efficiency during continuous operation
• Dust pollution affecting workshop cleanliness
• Material remaining inside bags after emptying
• Safety risks associated with manual knife cutting
• Inconsistent feeding speed causing production interruptions
• Difficulty integrating manual operations into automated production lines
• Poor working conditions leading to operator fatigue

For manufacturers handling hundreds of bags every hour, manual bag emptying limits overall production efficiency and increases operating costs.

The Starsplas Bag Opening Machine provides a fully automated solution for continuous bag emptying and material feeding.

The machine uses an intelligent layer-by-layer pallet separation system, allowing stacked bags to be automatically transferred to the cutting station without manual handling. A precision cutting device opens each bag cleanly while minimizing product residue. Materials are discharged into a vibrating screening system before entering the conveying equipment. Empty bags are automatically collected and compressed, while the integrated dust collection system maintains a clean production environment.

• Capacity from 400–800 bags/hour
• Automatic layer-by-layer pallet handling
• High material recovery with minimal residue
• Fully enclosed dust-free operation
• Automatic empty bag collection
• Continuous 24-hour production capability
• PLC touchscreen intelligent control
• Compatible with various conveying systems
• Reduced labor requirements
• Easy maintenance and reliable operation

The system enables manufacturers to achieve higher productivity, lower operating costs, and cleaner production while supporting fully automated material handling processes.

The Bag Opening Machine is widely used in industries requiring automatic unloading of bagged granular materials.

The machine is mainly designed for granular materials such as soybean, wheat, coffee beans, plastic pellets, PVC granules, resin particles and other bulk materials.

The standard processing capacity is 400-800 bags per hour. The actual capacity depends on bag size, material characteristics and production requirements.

Yes. The system can be customized for different packaging types including kraft paper bags, PE bags and woven bags.

The system is fully automatic. Operators mainly need to load bags or connect the machine with an automatic feeding system. Bag opening, emptying and bag collection are completed automatically.

Yes. The Automatic Bag Opening Machine can be connected with conveyors, storage systems, mixers, extruders and other industrial production equipment.
