Sunflower Seed Shelling Processing Line

Sunflower Seed Shelling Processing Line

The Sunflower Seed Shelling Processing Line from Shijiazhuang Xinlu Technology Co., Ltd. is engineered to extract kernels efficiently while minimizing damage to the seed. It combines dehulling, shell-kernel separation, and downstream cleaning into a continuous workflow.

Processing Stages

1. Pre-Cleaning: Raw seeds pass through screens and aspirators to remove dust, sticks, and oversized debris.

2. Cracking/Scalping: Specialized rollers apply calibrated pressure to crack shells, loosening kernels without crushing.

3. Shell-Kernel Separation: Pneumatic and mechanical separation units distinguish kernels (higher density) from shell fragments.

4. Kernel Polishing: A gentle polishing drum removes residual dust and fine shell particles.

5. Final Cleaning: Gravity tables and air screens perform final impurity removal and size grading.

Key Features

• Adjustable Roller Pressure: Fine control of cracking intensity for various sunflower varieties.

• Multi-Stage Separation: Combines pneumatic aspiration with vibrating sieves for high-purity output.

• Capacity Scalability: Modular sections permit throughput from 2 t/h to over 20 t/h.

• Energy-Efficient Drives: Variable-frequency motors reduce power consumption during low-load conditions.

• Enclosed Dust System: Integrated aspiration ductwork contains shell dust for easy collection.

Applications and Benefits
Food processors producing snack-grade kernels benefit from minimal kernel breakage and consistent appearance. Oilseed mills gain higher oil yields by delivering cleaner kernel feedstock to presses. The continuous design reduces manual handling and improves overall line efficiency.

Maintenance and Support
Maintenance includes inspection of roller bearings, screen media replacement, and duct cleaning. Shijiazhuang Xinlu Technology Co., Ltd. provides detailed manuals, spare parts supply, and training programs to ensure high availability and consistent performance.
