Automatic Packaging System for Granule Seeds in African Market

Customer profile: an agribusiness in Africa packing certified granule seeds for maize, beans and vegetable crops into 1 kg to 10 kg bags for regional distribution. A robust packing machine that handles dusty environments was the customer's core requirement.

The Challenge

Hand-filling seed bags was slow and inaccurate, with weight variation of up to 50 g per bag and frequent spillage of expensive treated seed. The customer needed a robust system that could run in a dusty environment, change quickly between bag sizes, and protect seed quality through gentle handling.

The Solution

Link Machinery supplied an automatic granule seed packaging system built around a vertical bagging machine with a high-accuracy electronic weigher and vibratory feed. The system handles pre-made bags and form-fill-seal operation, with date coding and batch counting integrated into the line.

Key Equipment Delivered

• Automatic granule seed bagging machine with touchscreen PLC
• High-accuracy weighing with fine-dosing for consistent bag weight
• Gentle vibratory feeding to protect seed coats
• Quick-change former set for 1–10 kg bag sizes
• Rugged dust-protected construction for harsh environments

The Results

• Output: production capacity more than doubled compared with manual bagging
• Accuracy: consistent fill weight within ±20 g, minimizing product loss
• Efficiency: one operator now supervises the complete line
• Flexibility: bag size changeover completed in minutes

Customer Feedback

“The machine handles our treated seed gently and the weighing is very consistent. Our bags now go out with the exact declared weight every time,” said the operations manager. The customer has since ordered a second line for its expanding export program.
