Sunflower Processing Line – High-Precision Seed Sorting and Cleaning

Hebei Julite Sorting Technology Co., Ltd. engineers sunflower seed lines to handle both snack seeds and oilseed grades:

1. Pre-Cleaning

• Vibrating sifters remove coarse debris.

• Aspirators strip out dust and loose hull fragments.

2. Destoning and Magnetic Separation

• Density-based destoners expel stones; magnetic separators catch metal bits.

3. Hull-Kernel Separation (for Oilseeds)

• Abrasive shellers crack hulls while preserving kernel integrity.

• Air classifiers separate light hull fragments from heavier kernels.

4. Optical Sorting

• High-resolution cameras and LED lighting detect kernel cracks, discoloration, and foreign seeds; pneumatic ejectors remove defects.

5. Grading and Moisture Control

• Size screens classify seeds for roasting or oil pressing.

• Moisture analyzers and low-temperature dryers set moisture to 10–12%.

6. Final Inspection and Packaging

• Metal detectors ahead of packaging.

• Bulk-bag or retail packing with multi-head weighers.

PLC/HMI integration provides full visibility into throughput, reject rates, and machine health, enabling prompt adjustments.
