Stages of a Wheat Seed Processing Line
Xinlu, one of the leading wheat seed processing line manufacturers, offers cutting-edge seed processing equipment that ensures purity, efficiency, and automation from start to finish.
Xinlu’s seed processing solutions are trusted by seed producers, cooperatives, and agricultural enterprises worldwide for their precision and reliability.
Stage 1: Pre-Cleaning and Impurity Removal
The first step of the wheat seed processing line is removing coarse impurities such as straw, stones, dust, and chaff. This step ensures that only healthy seeds proceed to the next stage.
Equipment Used in the Pre-Cleaning Stage
Vibratory screen cleaners for large debris
Aspirators to remove light impurities
Scalpers to handle high-volume material efficiently
Xinlu’s pre-cleaning systems are built for continuous operation, reducing downtime and increasing throughput.
Stage 2: Fine Cleaning and Air Screening
Fine cleaning enhances the purity of wheat seeds by separating them based on size, weight, and aerodynamic properties.
How Fine Cleaners Enhance Seed Purity
Xinlu’s air screen cleaners use multi-layer sieves and airflow systems to remove smaller impurities and ensure consistent seed grading. These machines achieve up to 99% purity levels, preparing the seeds for precise grading.
Stage 3: Grading and Size Separation
Grading ensures that all seeds are uniform in size and weight, improving germination consistency and mechanical planting accuracy.
Screen Graders and Gravity Separators
Screen graders separate seeds based on size, while gravity separators sort them by density, ensuring only mature, high-quality seeds continue in the line. Xinlu’s graders are adjustable for various wheat varieties and other cereals.
Stage 4: De-Stoning and Density Sorting
During this stage, any remaining heavy impurities such as stones, metal fragments, or soil particles are removed.
Advanced De-Stoning Technology by Xinlu
Xinlu’s de-stoners use vibration and air pressure to lift lighter seeds while heavier particles settle and are discharged. This process ensures purity before coating or drying begins.
Stage 5: Seed Treatment and Coating
Treatment improves seed health, while coating enhances protection against pests and fungal diseases.
Benefits of Seed Coating in Wheat Cultivation
Seed coatings can include fungicides, insecticides, and micronutrients that promote early root development. Xinlu’s coating machines deliver precise, uniform application that preserves seed viability.
Stage 6: Drying and Moisture Balancing
After treatment, seeds must be dried to a stable moisture level to prevent mold and deterioration during storage.
Moisture Control for Long-Term Viability
Xinlu’s dryers are equipped with temperature and humidity sensors that ensure uniform drying while conserving energy. The goal is to maintain wheat seed moisture between 10–12%, ideal for long-term preservation.
Stage 7: Final Packaging and Storage
The final stage involves weighing, bagging, labeling, and sealing the processed wheat seeds.
Automated Weighing and Sealing Systems
Xinlu’s automated packaging systems feature high-speed filling, accurate weight control, and barcode labeling for traceability. Properly sealed packaging prevents moisture ingress and contamination.
