Product Features

The Automatic Granule and Seed Weighing Filling Machine is built for performance, precision, and durability in demanding production environments.

High-Precision Multi-Head Weighing System: Utilizes advanced load cell technology and a sophisticated computer combination algorithm to achieve exceptional weighing accuracy, typically within ±0.5% to ±1.0%, ensuring every package meets strict net weight regulations and minimizing costly product overfill.

Fully Automated, High-Speed Operation: The entire packaging line is automated, handling bag feeding, forming, precision weighing, filling, sealing, and coding. This significantly reduces labor dependency, eliminates human error, and enables speeds of up to 60 bags per minute, dramatically boosting overall productivity.

Exceptional Versatility and Material Compatibility: Expertly engineered to handle a wide range of dry, free-flowing products. Its gentle handling is perfect for:

• Seeds: Chia seeds, flax seeds, quinoa, sunflower seeds
• Grains: Rice, beans, lentils, small grains
• Granules: Sugar, salt, instant coffee, tea granules
• Small Nuts and Dried Herbs

Intuitive User Control and Monitoring: Features a user-friendly PLC control system with a large industrial touchscreen HMI (Human-Machine Interface). Operators can easily set parameters, manage multiple product recipes, monitor real-time production data (speed, output, errors), and perform troubleshooting with minimal training.

Hygienic and Easy-Maintenance Design: Constructed with food-grade stainless steel (SUS304) at all product contact points. The machine’s smooth surfaces and open-frame structure facilitate quick cleaning, sanitization, and product changeover, ensuring compliance with GMP and other industry hygiene standards.

Robust and Reliable Construction: Built with high-quality components and a heavy-duty frame for stability and longevity. Designed for continuous 24/7 operation in industrial settings, it offers low maintenance requirements and outstanding durability for a high return on investment.

Integrated Packaging Line Solution: Can be seamlessly coupled with a vertical form-fill-seal (VFFS) machine to create bags directly from roll film. This integrated approach provides a compact, complete packaging line solution that saves floor space and streamlines the production flow from bulk material to finished, sealed pouches.
