Hebei Julite Sorting Technology Co., Ltd. presents its Sunflower Processing Line—an integrated solution engineered to meet the demands of seed cleaning, dehulling (if required), grading, and packaging for both snack-seed and oilseed markets. From raw material intake to final dispatch, each stage is designed for gentle handling of seeds, precise impurity removal, and consistent throughput.
Raw Intake & Preliminary Cleaning
Sunflower seeds enter through a calibrated feeding hopper onto a vibrating pre-cleaner. Oversized debris—stalk fragments, stones, and coarse soil—is removed via perforated screens. An aspirator then separates light impurities such as dust, chaff, and broken hull pieces, safeguarding downstream equipment and reducing wear.
Density & Magnetic Separation
Following initial cleaning, a destoner exploits differences in specific gravity to remove remaining stones and dense debris. A magnetic separator captures any ferrous contaminants introduced during cultivation or transport. These steps ensure product purity and protect precision sorting machinery.
Optional Dehulling
For oilseed lines, an abrasive sheller or impact cracker gently fractures the hull without damaging the kernel. The shell fragments are separated by an air-classification module, which carries lighter hulls away while allowing heavier kernels to continue. A subsequent drying unit adjusts seed moisture to target levels (typically 10–12 %), reducing risk of spoilage.
Optical Sorting & Grading
High-resolution cameras scan individual seeds on a narrow conveyor belt. Image-processing algorithms identify discolored, broken, or insect-damaged seeds. Precisely timed air jets eject these defects, delivering a visually uniform product. A multi-deck screener further grades seeds by size and thickness, enabling processors to supply product tailored for snack-roasting or oil-pressing applications.
Final Packaging & Control
Cleaned and sorted seeds pass through a final metal detector before being conveyed to packaging stations. Bulk-bag loaders, multi-head weighers, or automated pouch fillers deliver the finished product into customer-specified containers. A centralized PLC/HMI interface displays throughput rates, reject volumes, and machine status, while historical data logging supports traceability and audit compliance.
Applications & Support
Processed sunflower seeds from this line are ideal for roasted snacks, salad toppers, bird-feed mixes, and oil extraction. Hebei Julite Sorting Technology Co., Ltd. offers turnkey services—site assessment, civil design input, installation supervision, operator training, and after-sales maintenance—to ensure each processing line operates reliably and meets evolving production requirements.
