Sunflower Seed Dehulling and Cleaning Line

Sunflower Seed Dehulling and Cleaning Line

Shijiazhuang Xinlu Technology Co., Ltd. presents its Sunflower Seed Dehulling and Cleaning Line, engineered to efficiently remove shells and impurities from raw sunflower seed while preserving kernel integrity. Designed as a standalone processing solution, this line combines pneumatic dehulling with precision screening to deliver clean, dehulled kernels ready for downstream applications.

Process Flow

1. Intake and Pre‑Cleaning
   Raw seed is metered into a vibrating pre‑cleaner that removes large debris—stones, stalk fragments, and dust—via a dual‑deck screen and aspirator. This step protects the dehulling unit from excessive wear.

2. Rotary Dehuller
   The pre‑cleaned seed enters a low‑impact rotary dehuller, which applies adjustable rotor speed and chamber clearance to crack shells without fragmenting kernels. Pneumatic separation lifts loosened hull fragments away.

3. Shell‑Kernel Separation
   A downstream air‑suction separator directs light shell pieces into a collection duct, while heavier kernels pass through a perforated screen for further cleaning.

4. Fine Screening and Dedusting
   Dehulled kernels move onto a fine‑mesh aspirated screen that removes residual shell fragments, dust, and small stones, ensuring that only whole kernels advance.

5. Discharge and Buffering
   Clean kernels and separated shells are conveyed to distinct buffer bins via gentle belt conveyors, ready for packaging or further processing.

Key Features

• Adjustable Rotor Settings: Fine‑tune dehulling pressure and speed to suit varying seed sizes and shell thicknesses.

• Precision Airflow Control: Variable‑frequency blower modulates suction to optimize shell removal without aspirating kernels.

• Modular Screens: Quick‑release screen panels in multiple perforation sizes (1.5–3 mm) for rapid changeovers.

• Enclosed Dust Collection: Integrated cyclonic separator captures airborne particulates, maintaining plant hygiene.

• Stainless‑Steel Construction: Food‑grade contact surfaces resist corrosion and simplify cleaning procedures.

Benefits and Support
By combining gentle mechanical dehulling with targeted cleaning, this line achieves high kernel recovery rates while minimizing breakage.
