China Maize Seed Grading and Packaging System

China Maize Seed Grading and Packaging System

The China Maize Seed Grading and Packaging System from Shijiazhuang Xinlu Technology Co., Ltd. integrates precise size grading with automated packaging in a single production line, streamlining the transition from cleaned seed to sealed, labeled bags.

System Components

1. Final Grading Sieves

• A tri-deck sieving unit classifies kernels into uniform size grades. Quick-change frames allow rapid mesh swaps for different specifications.

2. Optical Inspection (Optional)

• An inline optical sensor can detect and remove discolored or defective kernels prior to packaging.

3. Buffer Hopper & Weighing Module

• Graded seed streams flow into hoppers equipped with load cells, enabling accurate batch weighing down to 0.1 kg tolerance.

4. Automated Bagging Machine

• Vertical form-fill-seal (VFFS) technology forms bags from film rolls, fills each to the designated weight, and seals them.

5. Labeling and Coding Station

• A printing unit applies batch numbers, dates, and barcodes directly onto each bag.

6. Finished-Goods Conveyor

• Sealed bags are transported to a palletizing zone or boxing station for downstream logistics.

System Highlights

• Recipe Storage: HMI stores weight, bag size, and fill speed settings for multiple product lines.

• High Performance: Capable of packaging up to 25 bags per minute, depending on bag size and seed density.

• Minimal Changeover: Tool-free adjustments reduce downtime when switching between grades.

• Built-in Dust Control: Localized extraction at bagging and weighing points maintains a clean work area.

Benefits for Processors

• Improved Consistency: Precise weighing and sealing ensure uniform package weights.

• Labor Savings: Automation reduces manual handling and counting tasks.

• Traceability: Integrated coding enables batch tracking from seed lot to field distribution.

• Compact Footprint: Vertical bagger and inline conveyors maximize space efficiency.
