China Wheat Seed Processing Line

China Wheat Seed Processing Line

The China Wheat Seed Processing Line developed by Shijiazhuang Xinlu Technology Co., Ltd. is designed to meet the practical needs of modern seed producers who require stable output quality, efficient impurity removal, and flexible configuration options. Wheat seed processing demands a balance between thorough cleaning and careful handling to preserve germination performance, and this processing line is structured to address both objectives within a unified system.

Overall Processing Concept

The wheat seed processing line integrates multiple functional stages into a continuous workflow, transforming harvested wheat into standardized seed suitable for planting, storage, or commercial distribution. Each section of the line can be configured independently or combined into a complete solution, allowing customers to match equipment selection with production scale and seed quality requirements.

Main Processing Stages

Raw Material Intake and Pre-Cleaning
Wheat seeds are introduced into the line through receiving hoppers equipped with controlled feeding mechanisms. The pre-cleaning unit removes large impurities such as straw, soil clumps, and oversized foreign matter. A combination of vibrating screens and aspiration airflow ensures that dust and light chaff are separated efficiently at an early stage.

Fine Cleaning and Screening
After pre-cleaning, wheat seeds pass through multi-layer screen cleaners. These machines separate seeds based on size and thickness, removing broken kernels, undersized grains, and remaining foreign seeds. Screen mesh sizes can be customized according to wheat variety and local agronomic standards.

Stone and Heavy Impurity Removal
A de-stoning module uses airflow and vibration to separate wheat seeds from stones and high-density contaminants. This stage is essential for protecting downstream equipment and ensuring product safety, especially in regions where harvested wheat contains a high percentage of soil-related impurities.

Density Separation
Gravity separation is applied to further improve seed quality. By sorting seeds according to density, immature, insect-damaged, or internally cracked kernels are removed. This step contributes significantly to improved germination consistency and field performance.

Optional Seed Treatment and Drying
For customers requiring treated wheat seed, a coating or dressing system can be integrated into the line. Treatment agents are applied evenly, followed by controlled drying to stabilize the coating layer. Moisture control ensures that treated seeds remain suitable for storage and transport.

Packaging and Storage Interface
Processed wheat seeds are transferred to buffer bins or directly to bagging and weighing systems. The line supports various packaging formats, including small retail bags and bulk agricultural sacks.
