Sesame Seed Processing Line

Sesame Seed Processing Line

Hebei Julite Sorting Technology Co., Ltd. presents its Sesame Seed Processing Line, a fully integrated system designed to transform harvested sesame into food-grade or hulled kernels ready for whitening, oil extraction, or paste production. This line incorporates cleaning, dehulling, drying, optical sorting, grading, and packaging modules into a continuous workflow.

Complete Processing Stages

1. Bulk Intake and Pre-Cleaning
   Raw sesame enters via a controlled conveyor into a vibrating pre-cleaner that removes stones, sticks, and coarse debris. An aspirator then extracts dust and light chaff to protect downstream dehulling equipment.

2. Dehulling Module (Optional)
   For products requiring hulled sesame, seeds pass through an abrasive dehuller. Moisture conditioning loosens hulls before gentle abrasion removes the outer skin. The resulting mixture enters an air classifier that separates hull fragments from kernels.

3. Drying Section
   Hulled kernels carry residual moisture from dehulling. A low-temperature dryer restores moisture to target levels (typically 6–8%), preventing microbial growth and preserving oil integrity.

4. Optical Sorting
   A high-resolution color sorter detects discolored, broken, or insect-damaged seeds. Each seed is scanned on a narrow belt, and air-jet ejection removes defects, ensuring a uniformly colored final product.

5. Precision Grading
   Multi-deck sieves separate seeds into uniform size fractions, supporting consistent packaging weights and product appearance.

6. Metal Detection and Packaging
   A final metal detector ensures no ferrous or non-ferrous particles remain. Cleaned and graded seeds are then conveyed to multi-head weighers and automatic bagging machines, filling bulk or retail packages with precise weight control.

Design Highlights

• Hygienic Construction: All seed-contact parts are made from food-grade stainless steel with sanitary welds and sloping surfaces to prevent residue buildup.

• Adjustable Controls: The PLC/HMI interface permits recipe management for different sesame varieties—black, white, or brown—and seasonal moisture variations.

• Modular Footprint: Processors can deploy only required modules—cleaning, dehulling, sorting—based on product goals, then expand later as production grows.

• Maintenance Efficiency: Quick-release hoppers, slide-out decks, and tool-free access panels streamline cleaning and component replacement.

Advantages in Operation

• Consistent Product Quality: Multi-stage cleaning and sorting remove foreign matter and defects, producing seeds ready for direct consumption, oil pressing, or paste manufacturing.

• Optimized Yield: Gentle dehulling and efficient optical sorting minimize kernel loss, maximizing usable output.

• Energy-Aware Design: Variable-frequency drives on motors and controlled airflow systems reduce energy consumption while maintaining throughput.

• Flexible Capacity: Lines handle capacities from 0.5 t/h in small facilities to over 10 t/h in industrial plants.
