Granule Packing Machine——Industrial Weighing & Packaging System
Granular products behave very differently from powders and liquids. Materials such as rice, sugar, coffee beans, seeds, fertilizers, and snack ingredients flow more freely, but they also introduce challenges like inconsistent particle size, bridging at feeding points, and weight variation during high-speed operation. These factors require a packaging system that can maintain both accuracy and stability under continuous production conditions.
The Granule Packing Machine developed by MIC Machinery is designed for precise weighing, stable feeding, and high-speed packaging of granular materials across food, agriculture, chemical, and daily-use industries. It is widely used in production lines where consistent weight control and clean packaging are essential for commercial distribution.
Unlike powder filling systems, granule packaging relies more on gravity feeding and multi-head weighing technology, ensuring each package reaches the target weight without damaging product integrity.
The granule packing process begins with raw materials being loaded into a storage hopper. Depending on the product type, the hopper may include vibration systems to ensure smooth flow and prevent material bridging. For products with uneven particle size, controlled feeding ensures stable distribution into the weighing system.
The material is then lifted to the multi-head weighing system or volumetric dosing unit. In a multi-head weigher, granules are distributed into several weighing buckets. A computer control system calculates the optimal combination of buckets to achieve the target weight with high accuracy.
Once the correct combination is selected, the material is discharged into a forming and packaging system. In vertical form-fill-seal (VFFS) machines, film material is shaped into bags, filled with granules, and sealed in a continuous cycle. For pre-made pouch systems, bags are automatically opened, filled, and sealed in sequence.
During operation, the system continuously monitors weight accuracy and adjusts feeding speed accordingly. For sensitive products such as snacks or coated granules, gentle discharge systems are used to avoid product damage.
After sealing, packages move to downstream systems such as date coding, metal detection, check weighing, and carton packaging. The entire process is coordinated by a PLC control system that ensures stable synchronization across all modules.

Maintenance
Granule packing machines require routine maintenance to ensure stable weighing accuracy and smooth feeding performance. Daily cleaning includes removing residual granules from hoppers, weighing buckets, and discharge channels.
Weekly inspections should focus on weighing sensor calibration, vibration system stability, and sealing performance. Any worn sealing components should be replaced promptly to maintain packaging integrity.
For sticky or coated granules, more frequent cleaning may be required to prevent buildup and ensure smooth material flow. Proper lubrication of mechanical components ensures stable long-term operation.
Routine maintenance helps maintain high weighing accuracy, reduce downtime, and ensure consistent packaging quality.
