The Automatic Sack Emptying System is a state-of-the-art, fully automated solution designed specifically for the efficient, dust-free unloading of powder and granular materials from 25 to 50 kg sacks. With the capability of handling up to 20–30 sacks per minute depending on sack size and product characteristics, this system ensures a seamless, hygienic, and high-capacity unloading process without the need for manual intervention. Designed with advanced features such as an automatic bag cutting mechanism employing rotary or guillotine blades, the system operates within an enclosed chamber to prevent contamination and dust emissions. Its integrated material discharge hopper is equipped with vibration or screw feeding, enabling smooth onward conveying directly to the process line via pneumatic, screw, or belt conveyors. Empty sack management is fully automated, featuring a discharge conveyor that transports waste sacks to an integrated compactor or waste bin, substantially reducing handling labor and waste volume. Constructed from GMP-compliant stainless steel (SS304 or SS316L), the system offers an enclosed dust-tight design augmented with optional HEPA filtration to maintain cleanroom standards. The PLC-based control panel with an HMI touchscreen interface provides intuitive operation and monitoring while ensuring safety through interlocks and emergency stops. Its automatic blade cleaning system minimizes clogging, guaranteeing continuous operation with low maintenance requirements and prolonged service life. This comprehensive sack emptying station is ideal for industries requiring hygienic, efficient, and high-throughput handling of bulk powder and granular materials in sealed packaging.

Automatic Bag / Sack Emptying Station
A Fully Automatic Sack Emptying Station is designed for dust-free, high-capacity unloading of powder and granular materials from 25–50 kg sacks without manual intervention.
In Automatic Bag Emptying system operates the roller conveyor line, the entire stack will be automatically conveyed into the catching position of bag slitter, the catching device of the bag slitter will come down to grab the whole layer bags layer by layer, and raise up to the set position, then move inside the machine, during this process the cutter blade will cut open the bags from the bottom, material emptying device to empty the material inside the bag, the material by gravity fall into the hopper, empty bag into the waste bag compactor, which collect, compact and extrude out the waste bag. When the whole stack bag is unpacked, the roller conveyor line will automatically transport the empty pallet to the pallet collector to complete automatic collection and stacking of the empty pallet.
Working Process:-
Sack Loading – Bags are placed on an infeed conveyor manually or via a pallet loader.
Automatic Bag Cutting – Rotary or guillotine blades cut open the sack in a controlled enclosed chamber.
Material Discharge – Contents fall into the receiving hopper, equipped with vibration or screw feeding for continuous downstream conveying.
Empty Bag Separation – Automatic removal of empty sacks via a discharge conveyor into a compactor or waste bin.
Dust Control – Integrated dust extraction ports ensure clean and safe operation.
Continuous Feeding – Material is directly fed into the process line via pneumatic, screw, or belt conveying.
