Automatic Layer Bag Emptying
EMP Series is a high-throughput automatic layer bag emptying system for palletized bag layers. Instead of emptying bags one by one, the system empties complete bag layers, discharges material to downstream conveying, storage or processing equipment, collects empty bags, and recovers and stacks empty pallets for continuous operation.
Layer-by-layer emptying · Palletized bags · Up to 120 layers/hour · Empty bag collection · Empty pallet recovery
EMP Series can be configured as a standard-throughput or high-throughput layer bag emptying platform according to required line capacity, pallet handling method and site layout. Both platforms are designed for complete-layer bag emptying, material discharge, empty bag collection and empty pallet recovery.
Standard Layer Bag Emptying System
EMP-S uses a gripper lifting arrangement while the pallet remains in position during the bag layer emptying cycle. It is suitable for projects requiring automatic complete-layer bag emptying with standard throughput and a simpler pallet handling motion.
Up to 60 layers/hour · Gripper lifting · Complete layer emptying · Empty bag collection · Empty pallet recovery
High-Speed Layer Bag Emptying System
EMP-H uses pallet lifting during gripper operation to shorten the emptying cycle and support higher-throughput complete-layer bag emptying. It is selected for production lines requiring faster palletized bag unloading and continuous downstream material feeding.
Up to 120 layers/hour · Pallet lifting · Complete layer emptying · High throughput · Empty pallet stacking
EMP is designed for palletized bag layers rather than one-bag-at-a-time emptying. Palletized bags enter the system, complete bag layers are handled and emptied, material is discharged to downstream conveying or storage equipment, empty bags are collected, and empty pallets are recovered and stacked according to the line layout.
Palletized bag stack enters the system
Complete bag layers are handled and emptied
Material is discharged to downstream equipment
Empty bags are collected
Empty pallets are recovered and stacked
EMP-H can reach up to 120 layers/hour. Based on 5 bags per layer and 50 kg per bag, this is equivalent to up to 30 t/hour under suitable project conditions. EMP-S can reach up to 60 layers/hour for standard-throughput applications. Final capacity depends on bag size, pallet pattern, material behavior, emptying stability and downstream conveying capacity.
EMP systems can be configured for palletized industrial bags such as woven PP bags, PE bags, paper bags and laminated bags. Final suitability depends on bag material, bag size, layer pattern, pallet stability and material discharge behavior.

Fine powder or highly dust-prone applications should be evaluated according to dust level, bag material, emptying behavior and downstream dust collection requirements.
Designed to empty complete palletized bag layers instead of processing bags one by one, supporting high-throughput raw material unloading.
EMP-S and EMP-H provide different throughput platforms according to required line capacity and pallet handling motion.
Emptied material can be discharged to downstream conveying, storage, hopper or processing equipment according to project requirements.
Empty bags are collected after layer emptying to reduce manual handling and support cleaner downstream operation.
Empty pallets are recovered and stacked according to the line layout to support continuous operation and reduce manual pallet handling.
System layout, guarding, empty bag handling, pallet handling and downstream interfaces are configured according to site conditions and process requirements.
EMP systems can be integrated with downstream conveying, storage silos, hoppers, processing equipment, dust collection systems and plant material handling lines. The final system layout depends on pallet pattern, bag material, material behavior, required capacity, empty bag handling, empty pallet recovery and available plant space.
EMP system selection depends on bag material, bag size, pallet pattern, layer stability, material flow behavior, dust level, required layer capacity, downstream conveying capacity, empty bag handling, empty pallet recovery and site layout. KWLE engineers evaluate these factors to select the proper EMP-S or EMP-H platform and project-specific configuration.
