Hebei Julite Sorting Technology Co., Ltd. introduces its Sunflower Seed Cleaning Machine, a comprehensive solution engineered to prepare raw sunflower seeds for further processing by removing a full spectrum of impurities. Designed to accommodate both snack-seed and oilseed production, this machine integrates mechanical screening, pneumatic aspiration, destoning, and magnetic separation into a continuous workflow that delivers consistently clean seeds with minimal kernel breakage.
Vibratory Pre-Screening
Raw sunflower seeds are fed via an adjustable vibrating feeder onto a perforated screen deck. The deck’s mesh size is selected to retain whole seeds while discharging oversized debris such as stalk fragments, stones, and clumps of foreign material. By adjusting the vibration amplitude and frequency, operators can optimize impurity removal without dislodging sound kernels.
Aspirator Dust and Husk Extraction
Beneath the screen deck, a controlled airflow system draws fine dust, loose hull pieces, and light chaff from the seed bed. Air volume and velocity settings are calibrated to lift only the unwanted light fraction, ensuring heavier whole seeds remain on the deck surface. This pneumatic cleaning stage significantly reduces airborne dust and enhances the accuracy of downstream optical or density-based separators.
Destoner Module
Following initial cleaning, the seeds advance to a gravity-based destoner. Here, calibrated vibration and airflow separate stones and heavy mineral contaminants that closely match seed size but differ in density. The destoner’s adjustable deck inclination and air pressure enable precise tuning to local field conditions and impurity profiles.
Magnetic Separation
A magnetic head positioned after the destoner captures ferrous particles that may have been introduced during harvest or transport. The magnetic elements are housed in a stainless-steel chamber, and a simple cleaning mechanism allows for rapid removal of trapped metal without halting production.
Final Grading (Optional)
For producers requiring size-graded output, an optional multi-deck sieving unit can be added. Seeds pass over successive screen decks with progressively finer apertures, classifying them into uniform size fractions. This stage supports applications where seed size uniformity is critical for roasting consistency or oil extraction efficiency.
Food-Grade Materials: All parts in contact with seeds are fabricated from 304 stainless steel with smooth welds and rounded corners to facilitate sanitation and comply with food-safety guidelines.
Adjustable Parameters: The control panel allows operators to set vibration intensity, airflow volume, and magnetic field strength. Recipe management stores optimal settings for different seed varieties or seasonal variations.
Maintenance Access: Slide-out decks, quick-release screen frames, and tool-free access panels permit rapid cleaning and component replacement. Centralized lubrication points simplify routine service tasks.
Compact Footprint: The machine’s vertical arrangement and modular design conserve floor space while providing easy integration into existing processing lines.
Consistent Quality: Multi-stage impurity removal ensures that only clean, intact seeds proceed to roasting, pressing, or packaging.
Reduced Kernel Damage: Gentle vibratory and airflow settings minimize mechanical stress, preserving seed integrity and maximizing product yield.
Energy Efficiency: Variable-frequency drives on blowers and vibratory motors adapt power use to actual load conditions, lowering operational costs.
Scalability: Models are available for throughputs ranging from 1 t/h to 12 t/h, accommodating small specialty producers and large industrial operations alike.
Hebei Julite Sorting Technology Co., Ltd. supports each Sunflower Seed Cleaning Machine with site evaluation, installation supervision, operator training, and preventive-maintenance programs to ensure reliable, long-term performance and compliance with evolving food-safety standards.
