Powder Spoon Packing Machine

Hygienic, Accurate & Integrated Powder and Spoon Packaging

Milk powder is a fine, lightweight, and highly hygienic-sensitive product. During pouch packaging, special attention must be paid to dust control, filling accuracy, sealing quality, and overall product safety.

ZOMUKIKAI has developed its latest powder spoon-in-bag packaging machine, specifically designed for milk powder and other nutritional powders, offering a reliable and clean turnkey solution.

Hygienic Powder Handling with Vacuum Conveying

To meet strict hygiene requirements, the system uses vacuum powder conveying for material feeding.

Advantages:

• Fully enclosed powder transfer
• Prevents contamination and dust exposure
• Improves operator safety
• Complies with food-grade hygiene standards

8-Station Premade Pouch Packaging Process

ZOMUKIKAI’s premade pouch packaging machine integrates multiple functions within only 8 stations, achieving a compact, efficient, and stable layout:

1. Automatic pouch feeding
2. Date coding
3. Zipper opening
4. Pouch opening
5. Powder filling
6. Scoop insertion
7. Dust removal
8. Air evacuation, heat sealing & finished pouch discharge

Despite the limited number of stations, all key processes are completed automatically with high efficiency.

Powder Filling: Accuracy Across 10–1000 g

The system is designed for 10–1000 g powder filling, with special engineering considerations based on filling weight.

10–500 g Powder Filling

• Standard screw auger filling system
• Powder weight accuracy is not affected by internal pressure
• Stable and repeatable dosing performance

Above 500 g Powder Filling

When powder weight exceeds 500 g, vacuum conveying may cause uneven pressure inside the screw auger hopper, which can lead to larger dosing deviations.

ZOMUKIKAI Solution: Horizontal Screw Conveyor Buffer

• Acts as a buffering stage during powder transfer
• Ensures uniform material feeding
• Reduces pressure fluctuation inside the auger hopper
• Significantly improves filling accuracy for large-volume powder packaging

Spoon Insertion System

Each pouch requires one spoon per bag.

• Spoon feeding is achieved using a vibratory bowl feeder
• Automatically counts and delivers one spoon per pouch
• Stable, reliable, and suitable for continuous operation
• Ensures consistent spoon placement without manual intervention

Advanced Dust Removal System

Dust control is a critical focus in milk powder packaging.

Special Powder Hopper with Vacuum Dust Collection

• Powder hopper is connected to a vacuum dust collector
• During powder discharge, airborne dust around the hopper is immediately extracted

Pouch Mouth Dust Cleaning

• The pouch mouth is gently tapped to remove residual powder
• Loose powder is extracted by the vacuum dust system
• Prevents powder residue from affecting heat sealing quality

Dust Recovery

• Collected powder can be recycled and reused, reducing material waste

Air Evacuation and Final Sealing

After powder and scoop insertion:

• Excess air inside the pouch is evacuated
• The pouch is heat sealed
• The pouch is shaped and stabilized
• Finished products are discharged smoothly via conveyor

This process improves package appearance, sealing strength, and shelf stability.
