Sunflower Seed Double Air Screen Cleaner

Sunflower Seed Double Air Screen Cleaner

Shijiazhuang Xinlu Technology Co., Ltd. presents the Sunflower Seed Double Air Screen Cleaner—a two-stage air-screen system engineered to remove both coarse and fine impurities from sunflower seed batches in a single integrated line. The first stage employs a robust screening deck with large-aperture meshes to capture oversized debris—such as stalk fragments, clods, and field trash—while a calibrated aspiration airflow draws off light materials like dust and loose hull fragments. Material that passes through this primary screen automatically transitions to the second stage, which features a finer mesh deck and a precisely controlled air column. Here, residual impurities—including small husk particles, broken seeds, and insect fragments—are separated without subjecting the kernels to excessive mechanical stress.

Key design elements include independent vibration and airflow controls for each stage, allowing operators to adapt the machine’s performance to varying seed conditions and moisture levels. The double-deck configuration reduces carryover of contaminants into downstream processes, boosting overall throughput and reducing the need for manual inspection. All contact surfaces are fabricated from food-grade stainless steel, and the enclosed housing with integrated dust collection minimizes airborne particulates, ensuring compliance with hygiene standards.

Operationally, this cleaner processes up to 20 t/h of raw sunflower seed, depending on feed quality and cleaning targets. The dual-stage approach not only enhances impurity removal efficiency—achieving rejection rates above 90% for common contaminants—but also preserves kernel integrity, an essential consideration for both oilseed and snack-grade markets. Energy consumption is optimized through a variable-frequency drive on the aspirator fans, which modulates airflow to match real-time load conditions.

Routine maintenance is straightforward: screen meshes are mounted on quick-release frames for rapid cleaning or replacement, while aspiration filters are accessible via hinged panels. Shijiazhuang Xinlu Technology Co., Ltd. offers comprehensive maintenance manuals, spare-parts kits, and on-site training to support customers in maintaining peak performance. With its two-stage cleaning logic, the Sunflower Seed Double Air Screen Cleaner provides a reliable solution for processors seeking thorough impurity removal in a compact, user-friendly package.
