Hebei Julite Sorting Technology Co., Ltd. offers the Sunflower Processing Line, a complete system engineered to convert raw sunflower seeds into clean, graded product ready for oil extraction, roasting, or seed sale. Built to accommodate seed sizes and moisture variations typical of field-harvested sunflower, the line integrates multiple stages that work in sequence to ensure consistent throughput and product integrity.
Raw Seed Preparation and Pre-Cleaning
Sunflower seeds enter the line via an adjustable metering conveyor, which feeds them onto a vibratory pre-cleaner. Here, oversized debris such as stalk fragments, stones, and weeds is removed by a perforated screen. An aspirator located beneath the screen draws out dust, broken hull fragments, and light chaff, reducing airborne particulates and protecting downstream components.
Density-Based Separation and Destoning
After pre-cleaning, seeds pass through a gravity separator designed to remove both light and heavy impurities. By adjusting vibration frequency, deck inclination, and airflow volume, operators can fine-tune the separation to local field conditions. The destoner unit then employs a dense deck vibration and calibrated airflow to eject stones and similar‐size mineral fragments, safeguarding optical or magnetic modules further along the line.
Optional Dehulling and Sizing
For processors requiring hulled seeds, an optional dehulling module can be integrated. In this stage, seeds are gently abraded to remove the outer hull without damaging the kernel. A subsequent air classifier separates hull fragments from kernels. Following this, multi-deck screening classifies seeds into uniform size fractions, supporting even roasting or consistent oil-extraction yields.
Final Inspection and Packaging
An optical sorting system scans individual seeds for discoloration or insect damage and uses brief air jets to eject defects. A metal detector provides a final safeguard against ferrous contaminants. Cleaned and sorted seeds are then directed to multi-head weighers and bagging machines, delivering precise fill weights into bulk or retail packages.
Key Benefits and Support
This Sunflower Processing Line strikes a balance between cleaning efficiency and kernel preservation, minimizing breakage and dust generation. The PLC-controlled interface allows recipe storage for different seed varieties, and tool-free access panels simplify routine maintenance. Hebei Julite Sorting Technology Co., Ltd. provides site assessment, installation supervision, operator training, and preventive-maintenance services to support uninterrupted operation and product consistency.
