Precision Handling in Sesame Seed Processing Lines

Precision Handling in Sesame Seed Processing Lines

Sesame seeds, among the smallest commercial oilseeds, require uniquely engineered solutions to prevent loss and damage during processing. A dedicated Sesame Seed Processing Line emphasizes micro-scale cleaning, static control, and optical precision to achieve >99.5% purity for culinary or oil extraction markets.

Specialized Process Flow:

1. Pre-Screening: Vibratory screens with micro-mesh (0.8–1.2mm) remove sand and coarse debris.

2. Aspiration: Multi-stage cyclones eliminate dust, plant stems, and immature seeds.

3. Gravity Separation: High-precision gravity tables segregate seeds from pebbles of similar size.

4. Color Sorting: Ultra-HD optical sorters with 360° inspection detect and eject discolored, moldy, or foreign material (e.g., rodent hairs).

5. Washing & Drying (Optional): For dehulled seeds: flotation tanks separate hulls; spin dryers reduce moisture.

6. Static & Dust Control: Ionized air knives and HEPA filtration ensure seed flow and workplace safety.

7. Packaging: Vacuum or gas-flushed packaging in moisture-barrier bags (250g–20kg).

Technical Sophistication:

• Loss Minimization: Enclosed conveyors (vibratory belts, vacuum tubes) prevent spillage.

• Hygiene: USDA-compliant finishes; easy-access design for sanitation.

• Optics: Dual-laser scanners detect translucent husk fragments on hulled seeds.

Capacity & Versatility:
Lines process 200 kg/h to 2 T/H, handling white, black, or golden sesame. Modular add-ons include infrared toasting or cold-pressing units.
