Wheat Seed Cleaning Machine

Wheat Seed Cleaning Machine

Hebei Julite Sorting Technology Co., Ltd. offers its Wheat Seed Cleaning Machine, purpose-built to process wheat for planting, milling, or food-grade applications. This multi-stage system integrates mechanical and pneumatic cleaning to deliver uniform, contaminant-free wheat kernels.

Cleaning Process Flow

1. Pre-Screening Deck
   Wheat enters a vibrating screen that removes large impurities—straw pieces, stones, and oversized kernels. Screen mesh sizes are selected to retain healthy wheat and discharge unwanted materials.

2. Aspirator Unit
   Below the screen, an aspirator draws air through the wheat layer, lifting and expelling dust, chaff, and light husk fragments. Adjustable airflow and deck incline optimize cleaning without entraining sound kernels.

3. Destoner Module
   Using calibrated vibration and airflow, the destoner separates dense contaminants—stones and heavy foreign objects—from wheat kernels of similar size but lower density.

4. Magnetic Separator
   A permanent-magnet head captures any ferrous particles, protecting downstream milling or seed-treatment equipment.

5. Precision Grading Sieves
   Multi-deck sieving classifies kernels into size grades, ensuring uniform germination rates for seed lots and consistent flour extraction rates for milling.

6. Final Inspection Station
   An optional optical sensor unit scans kernels for discoloration, shriveling, or insect damage, diverting defective kernels for further cleaning or rejection.

Machine Construction Highlights

• Stainless-Steel Contact Parts: All seed-contact components are 304 stainless steel, facilitating sanitation and reducing corrosion risk.

• Adjustable Controls: A centralized PLC/HMI panel allows operators to set vibration amplitude, airflow volume, and screen selection; preset recipes simplify lot changeovers.

• Robust Frame: Welded steel supports minimize structural flex under continuous vibration, ensuring consistent performance.

• Maintenance Access: Tool-less screens, quick-release panels, and centralized lubrication points reduce downtime for cleaning and servicing.

Benefits in Operation

• High Purity Output: Multi-stage cleaning removes dust, chaff, stones, and metals to meet seed-certification or food-grade standards.

• Uniform Lot Quality: Grading sieves produce homogeneous size fractions, improving downstream process predictability.

• Reduced Kernel Damage: Controlled vibration and airflow preserve kernel viability for planting and minimize breakage for milling.
