Full automatic 25kg powder packing line for bulk bags | filling sealing sewing

Products Video

This equipment offers strong versatility and is widely suitable for powdered materials in various industries such as chemical, food, dairy, and condiments.

• *Applicable Materials:** Seasoning powder, milk powder, wheat flour, starch, feed powder, food additives, chemical powders, etc.
• *Packaging Specifications:** Suitable for multiple standard packaging weights within the range of 15-25kg.
• *Bag Compatibility:** This equipment is suitable for flat-bottom composite packaging bags. As long as the size/dimensions of the packaging bag fall within the adjustable range set by the equipment, they are universally applicable without complex modifications needed for changing bag types.

1. Fully Automated Process, Operable by One Person

The entire line features a high degree of automation. It only requires one operator to load empty bags in bulk into the "bag magazine with a capacity of 50-60 bags". Subsequent actions including bag picking, opening, filling, air evacuation, secondary filling, vacuuming/nitrogen flushing, inner bag sealing, outer bag heat sealing, and sewing are all completed automatically by the equipment, significantly reducing labor requirements.

2. Modular Process Ensures Packaging Quality

• A. Filling & Air Evacuation: Utilizes a unique process of "Primary Filling + Material Air Evacuation + Secondary Filling + Vacuuming". By combining material air evacuation and vacuuming, it effectively removes air from inside the bag, preventing loose/fluffy bags due to powdered material, ensuring a solid and neat package, and improving stack stability and transport safety.
• *B. Efficient Sealing: The inner bag uses reliable heat sealing for effective moisture and leak protection. For the outer bag, based on customer requirements, it provides secure bag mouth cleaning, edge trimming, inner bag heat sealing, outer bag sewing, or outer bag heat sealing with thermal melt paper, ensuring seal strength.

3. Core Components & Superior Materials Ensure Long-Term Stability

• A. Electrical Control System: Key control components (such as PLC, HMI, Servo Motors) use German Siemens brands. Other electrical components use French Schneider brands. The control system is stable and reliable, with low failure rate and long service life.
• B. Contact Materials: All parts contacting the material are made of high-quality 304 stainless steel, offering corrosion resistance, wear resistance, complying with hygiene and safety standards for the food and chemical industries, and are easy to clean and maintain.

4. High Capacity & High Precision, Balancing Efficiency and Profitability

• A. Excellent Capacity: Stable output of 3-4.5 tons/hour, meeting the pace requirements of most large-scale production lines.
• B. Weighing Accuracy: Equipped with high-precision sensors and advanced weighing control algorithms, dynamic weighing accuracy can reach ±0.1% (i.e., ±15-30g/bag). This effectively avoids raw material waste from underfilling or overpacking, saving costs for enterprises.
• C. Durability: Designed service life of over 10 years. Features high-end electrical controls, 304 stainless steel material, and is easy to clean.
