Shijiazhuang Xinlu Technology Co., Ltd. is proud to present its Sunflower Seed Gravity Separator, a precision density‑based cleaning solution engineered for both oilseed and snack‑grade sunflower processing. Utilizing the principle of gravity stratification, this machine efficiently separates dense, intact kernels from lighter contaminants and broken fragments, ensuring uniform seed quality and optimizing downstream performance.
Working Principle
The sunflower seed feed is uniformly distributed across an inclined, oscillating deck. Simultaneously, an adjustable upward air stream passes through the seed layer. Heavier, fully developed seeds sink into the deck grooves and migrate toward the clean‑seed outlet under the influence of deck vibration and slope. Conversely, lighter materials—such as husk fragments, dust, and immature or broken seeds—are lifted by the airflow and carried away to the reject channel. Precise control over deck angle (0–10°), stroke amplitude (3–8 mm), and airflow volume (0.5–4 m³/min) allows operators to adapt to seasonal variations in seed moisture and impurity load.
Key Features
Interchangeable Deck Mats: Multiple groove patterns and depths support varied sunflower seed sizes, from small confectionery types to large oilseed hybrids.
Variable‑Frequency Fan: A VFD‐driven aspirator fan maintains consistent suction even as filter elements load, ensuring stable separation dynamics.
Gentle Vibration Drive: Counterbalanced vibratory motors generate smooth oscillations, reducing mechanical damage and safeguarding germination.
Modular Construction: Quick‑release clamps and hinged access panels permit rapid deck mat changes and internal inspections without full disassembly.
Integrated Dust Collection: Enclosed housing directs aspirated fines and husk particles to an external cyclone or bag filter, maintaining a clean work environment.
Operational Performance
In field trials, the Sunflower Seed Gravity Separator achieved impurity removal rates exceeding 90% while maintaining kernel breakage below 1%. Typical throughputs range from 10 t/h to 25 t/h, depending on seed condition and desired purity level. By delivering a cleaner feed to oil presses or snack‑packing lines, this equipment reduces wear on downstream machinery and enhances final product appearance and oil yield.
Maintenance and Support
Routine maintenance tasks include inspecting and replacing worn deck mats, cleaning aspirator filters, and lubricating vibration bearings. Shijiazhuang Xinlu Technology Co., Ltd. provides comprehensive maintenance manuals, preventive maintenance schedules, and on‑site training to help customers maximize uptime and extend component life.
