China Maize Seed Processing Line

China Maize Seed Processing Line

Shijiazhuang Xinlu Technology Co., Ltd. is pleased to offer its China Maize Seed Processing Line, engineered to transform raw maize harvest into uniform, high-quality seed lots ready for planting or further treatment. This turnkey line combines multiple cleaning and grading stages into a continuous, automated workflow.

Process Flow

1. Bulk Reception & Feeding

• Maize is received via a hopper with level sensors that control a variable-speed feeder, ensuring consistent material flow.

2. Pre-Cleaning Stage

• A vibratory screen removes oversized debris (cobs, stalk fragments) while an integrated aspirator eliminates fines such as dust and light chaff.

3. Magnetic & De-Stoning Module

• A magnetic separator captures any metallic contaminants; a downstream de-stoner separates stones and heavy clods using airflow and deck oscillation.

4. Sieving and Sizing

• Multi-deck sieving units classify kernels into distinct size fractions. Mesh apertures can be quickly changed to match variety specifications.

5. Density Separation

• A gravity separator stratifies kernels by density to remove broken or undersized seeds, improving overall uniformity and germination potential.

6. Final Conveyance to Buffer Bins

• Graded, cleaned maize is conveyed to buffer bins for temporary storage before treatment or packaging.

Key Design Features

• PLC‐Based Control System: Central touchscreen panel with recipe management for different maize varieties.

• Variable‐Frequency Drives: All major motors and fans are VFD-equipped, optimizing energy use according to load.

• Hygienic Construction: Contact surfaces in food-grade stainless steel and enclosed dust‐collection ducts maintain plant cleanliness.

• Modular Layout: Each module can operate independently for maintenance or be bypassed if not required.

• Gentle Handling: Low‐impact chutes and isolators protect kernel integrity.

Operational Advantages

• Consistent Quality: Precise grading and density separation yield uniform seed lots.

• High Throughput: Configurations from 5 t/h to 50 t/h accommodate small research facilities to large commercial operations.

• Reduced Waste: Effective impurity removal decreases rework and maximizes usable seed.

• Scalable Investment: Modular design allows incremental expansion as capacity needs grow.

Maintenance and Support
Routine checks include screen mesh inspections, aspirator filter cleaning, and lubrication of bearings. Shijiazhuang Xinlu Technology Co., Ltd. provides comprehensive documentation, spare-parts kits, and on-site training to ensure reliable, long‐term performance.
