Shijiazhuang Xinlu Technology Co., Ltd. specializes in the design and manufacture of turnkey peanut seed cleaning and grading plants that cater to the needs of modern processing operations. From small-scale cooperatives to large industrial facilities, our plants are engineered to remove foreign materials, separate kernels by size, and deliver uniformly graded peanut seed batches ready for roasting, oil extraction, or further value‑added processes.
Plant Configuration and Workflow
Intake & Pre‑Cleaning
Raw peanuts are fed via a belt or screw conveyor into a vibratory pre‑cleaner. Dual‑deck screens remove oversized debris—such as stones, clods, and plant stalks—while an aspirator extracts dust and lightweight hull fragments.
Magnetic Separation
A high‑strength magnetic drum captures any residual metal fragments, ensuring the safety of downstream equipment.
De‑Stoning Module
Adjustable airflow and an oscillating deck separate heavy stones from the peanut flow, safeguarding delicate grading components.
Sieving & Grading
Multi‑deck sieving machines classify kernels into small, medium, and large fractions. Screens can be quickly changed to match different peanut varieties or market specifications.
Final Dedusting
A dedicated aspirator module polishes the graded kernels, removing any residual fines before bulk discharge.
Key Design Features
Modular Construction: Each module—pre‑cleaner, magnetic separator, de‑stoner, sieves, and aspirator—is a self‑contained unit, allowing flexible plant layouts and capacity adjustments from 5 t/h to 50 t/h.
Adjustable Process Parameters: Operators control vibration amplitude, screen inclination, and airflow rates via a centralized PLC interface, enabling rapid optimization for varying seed moisture levels.
Food‑Grade Materials: All contact surfaces are stainless steel or FDA‑approved polymer to maintain hygiene standards and facilitate cleaning.
Enclosed Dust Collection: Integrated ducting and cyclonic separators capture airborne particulates, ensuring compliance with workplace air‑quality regulations.
Operational Advantages
Consistent Product Quality: Uniform grading reduces manual sorting and rework, increasing overall throughput.
Reduced Equipment Wear: Effective removal of stones and metal extends the service life of screens and conveyors.
Scalability: Additional grading decks or aspirator stages can be added as processing volumes grow.
Energy Efficiency: Variable‑frequency drives on fans and motors optimize power use according to real‑time load.
Maintenance and Support
Routine maintenance—screen inspection, filter replacement, and lubrication of vibrating bearings—can be conducted during scheduled downtimes. Shijiazhuang Xinlu Technology Co., Ltd. provides detailed maintenance manuals, on‑site commissioning, and spare‑parts kits to ensure maximum uptime and reliable long‑term performance.
