The BDH DC-S25-NJ is a cutting-edge fully automatic double helix granule packaging machine, tailor-made for 25kg large-size packaging of free-flowing granular materials. Engineered for industries including food, feed, chemicals, and pharmaceuticals, this machine integrates advanced automation and precision technology to redefine efficient packaging workflows. Whether handling white sugar, rice, salt, feed pellets, or chemical raw materials, it delivers consistent, reliable performance that meets strict industrial standards.
At its core, the machine features a dual double helix feeding system that ensures uniform material flow, eliminating bridging or clogging issues common in granular packaging. It combines automatic weighing, bag retrieval, bag opening, filling, sealing, and package delivery into a seamless workflow. Vacuum suction cups retrieve bags from the integrated bag library, while PLC control and photoelectric switches govern every step—supported by a real-time detection system that triggers alarms for anomalies like empty bags or misfeeds.
Designed for free-flowing granular products, it handles a wide range: white sugar, monosodium glutamate, glucose, rice, salt, feed, nuts, solid medicines, pesticides, chemical raw materials, and building materials. It accommodates multiple bag types, including craft paper coated bags, coated woven bags, 0.2mm-thick plastic bags, and woven bags with PE liners—all in a pillow open pocket shape. Bag sizes are customizable within L:810mm-960mm and W:410mm-650mm to fit diverse product needs.
Industries like food processing, feed production, and chemical manufacturing face mounting pressure to cut labor costs and boost efficiency. Manual 25kg granular packaging is time-consuming, error-prone, and costly in the long run—driving strong demand for fully automatic solutions. The DC-S25-NJ addresses this gap, enabling unmanned production lines that scale with medium to large manufacturers’ needs.
Modern markets demand stricter weight consistency, with most industries requiring packaging deviations of ≤±0.2%. The DC-S25-NJ’s double helix feeding and high-precision weighing system exceed this standard, making it a top choice for brands prioritizing product quality, compliance, and customer trust.
From bag retrieval to final delivery, the machine operates without manual intervention. The vacuum suction cup bag-taking mechanism ensures reliable bag handling, while photoelectric detection prevents costly errors like empty bags or improper sealing—maximizing uptime and productivity.
The dual helix design delivers consistent material flow, achieving weighing precision of ≤±0.1-0.2%. This minimizes material waste and ensures every 25kg bag meets exact weight requirements, critical for regulated industries like food and pharmaceuticals.
Built for continuous industrial use, the machine boasts a robust construction and 8KW total power for stable performance. Its compatibility with multiple bag materials and customizable sizes makes it adaptable to diverse product lines, reducing the need for specialized equipment.
With precision ranging from ±0.1% to ±0.2%, the DC-S25-NJ outperforms industry benchmarks for granular packaging. The double helix feeding system’s precise control eliminates overfilling or underfilling, ensuring compliance with quality standards.
Operating at 3–8 bags per minute, it strikes the perfect balance between speed and accuracy—ideal for large-scale production. Its automated workflow cuts cycle times significantly compared to manual or semi-automatic alternatives.
Running on 380/220V 50-60Hz (TN-S) power, the machine uses just 8KW of total power for efficient operation. It requires a gas consumption of 6kg/cm² 0.4-0.6cm³/min, compatible with standard industrial gas systems to minimize operational costs.
We offer flexible bag size customization within L:810mm-960mm and W:410mm-650mm, as well as specialized bag material adaptation for unique product characteristics. Our technical team adjusts the double helix feeding system for specific granular types—from fine powders to coarse pellets.
Backed by a dedicated engineering team, we provide comprehensive after-sales support, including installation, training, and maintenance. Our responsive service ensures minimal downtime and optimal machine performance.
Designed for heavy-duty use, the DC-S25-NJ is rigorously tested to withstand continuous operation in harsh industrial environments. Its durable components and intelligent detection system reduce maintenance needs and extend service life.
Flow of work
The bag mechanism uses the vacuum suction cup to take the bag from the bag library, transport the automatic open bag on the bag manipulator on the bag to automatically import the bag, the whole process is accompanied by the detection system, the whole process is intelligently controlled by PLC, photoelectric switch, detection and alarm. Ensure that the whole process is stable, reliable and continuous operation.
