Shijiazhuang Xinlu Technology Co., Ltd. presents its comprehensive Sunflower Seed Shelling Processing Line, engineered to separate the seed kernel from the hull with high efficiency and minimal kernel breakage. This line is suitable for both oilseed production and snack-grade seed processing.
Process Workflow
Pre-cleaning: Vibratory screens and aspirators remove stones, dust, and chaff to protect downstream equipment.
De-hulling: A pair of friction rollers gently crack the outer shell without crushing the kernel. Roller gap and speed are adjustable to match seed moisture and variety.
Separation: Post-hulling, an air-screen cleaner separates lighter hull fragments, while a vibrating sieve classifies kernels by size.
Magnetic and Destoner Modules: Optional magnetic and destoner units remove any metal debris or heavy contaminants.
Polishing (Optional): A tumble-polishing drum imparts a smooth, glossy finish to snack-grade kernels.
Equipment Highlights
Gentle Roller Design: Cushioned rollers prevent over-crushing, achieving breakage rates below 3%.
Adjustable Airflow and Deck Vibration: Fine-tune separation parameters for optimal hull removal.
Automated Controls: PLC system synchronizes conveyor speeds, roller pressure, and airflow for consistent performance.
Modular Layout: Equipment skids can be arranged to fit existing plant configurations and expanded for higher capacities.
Hygienic Construction: Quick-release bearings and smooth surfaces facilitate thorough cleaning between production runs.
Performance Outcomes
In production tests, the Sunflower Seed Shelling Processing Line achieved kernel recovery rates above 92% for black-oil varieties and above 95% for confection types. Throughput capacities range from 2 t/h for pilot-scale setups up to 20 t/h for large-scale installations.
After-sales Support
Shijiazhuang Xinlu Technology Co., Ltd. offers end-to-end support, from plant-layout consultation and onsite commissioning to operator training and long-term maintenance contracts. Spare-parts kits, including rollers, screens, and belts, are stocked for rapid dispatch.
