Sunflower Seed Processing Line Factory

Sunflower Seed Processing Line

Shijiazhuang Xinlu Technology Co., Ltd. introduces its Sunflower Seed Processing Line, a standalone solution designed for producers who require precise cleaning, grading, and preparation of sunflower seeds for oil extraction or snack markets. Engineered for moderate to high throughputs (5–20 t/h), this line combines mechanical and pneumatic modules to ensure consistent product quality while preserving kernel integrity.

Working Principle and Sequence

1. Bulk Feeding & Distribution

• Raw sunflower seeds enter via a vibrating feeder that ensures even spread onto subsequent modules.

2. Pre‑Cleaning Module

• A two‑deck vibrating screen removes coarse debris (stalk fragments, stones, clods).

• An integrated aspirator draws off light impurities such as dust and loosened hull particles.

3. Magnetic Separation

• A magnetic drum captures any ferrous contaminants, protecting downstream equipment.

4. De‑Stoning Unit

• Controlled airflow and deck vibration separate heavier stones and soil particles from the seed stream.

5. Gravity Separation

• A standalone gravity separator stratifies kernels by density. Denser, intact seeds sink into deck grooves and advance to the clean outlet; lighter, broken kernels and fines are removed via an air stream.

6. Final Dedusting

• A secondary aspirator module polishes the cleaned seeds, lifting residual dust and fine hull fragments before transfer to packaging.

Key Components

• Vibrating Feeder: Stainless steel tray with adjustable amplitude to suit varying feed rates.

• Aspirator Fans: Frequency‑controlled blowers deliver airflow up to 3 m³/min, adjustable per module.

• Screen Decks: Interchangeable mesh panels (3–6 mm openings) mounted on quick‑release frames.

• Magnetic Drum: 600 mm diameter, high‑intensity magnets for effective metal removal.

• Gravity Separator: 2 m² deck area, adjustable stroke (3–6 mm) and deck incline (0–8°).

• Control Panel: PLC with touchscreen interface stores up to 10 cleaning recipes and displays throughput, fan speed, and deck load.

Use Cases and Benefits

• Oilseed Mills: Removes foreign matter and broken seeds to improve pressing efficiency and oil clarity.

• Snack Producers: Enhances visual appeal by eliminating discolored or damaged kernels.

• Small to Medium Plants: Compact footprint (≈12 m²) allows installation in existing facilities without major renovations.

Customization Options

• Deck Configurations: Fine or coarse groove mats for different seed varieties (black oil vs. confection).

• Capacity Scaling: Multiple feeder and separator modules can be added for throughputs up to 30 t/h.

• Dust Collection: Optional cyclonic separator for central dust management systems.

• Automation: Integration of load‑cells for real‑time mass flow monitoring and automatic feed adjustment.
