Grain Cleaning and Grading Machines

Grain Cleaning and Grading Machines

Hebei Julite Sorting Technology Co., Ltd. offers its Grain Cleaning and Grading Machines, engineered to handle cereals such as wheat, barley, rice, and oats. These machines integrate multiple separation principles—mechanical screening, aspiration, gravity, and magnetic—to deliver high‑quality grain suitable for milling, brewing, and animal feed.

Multi‑Stage Cleaning and Grading Sequence

1. Vibratory Pre‑Cleaner: Removes large foreign bodies and aggregates, protecting downstream equipment.

2. Aspirator: Extracts light debris and dust using controlled airflows.

3. Destoner: Separates stones and heavy particles by combining vibration with calibrated airflow.

4. Magnetic Separator: Captures metallic fragments for product safety.

5. Multi‑Deck Sieving: Classifies grain into defined size fractions, enabling consistent milling or abrading.

6. Gravity Grading (Optional): A gravity separator can be added to separate grain based on minor density differences, critical for high‑value applications like malting barley.

Machine Features

• Configurable Layout: Cleaning and grading modules are skid‑mounted and bolt‑together, allowing processors to customize the line for specific grains and capacities.

• Intuitive Controls: A PLC/HMI interface provides real‑time data on feed rate, reject levels, and throughput. Operators can save and recall job parameters for different grain varieties.

• Durable Build: Heavy‑gauge frames support continuous operation, while stainless‑steel seed contact surfaces simplify sanitation.

• Accessibility: Quick‑open covers and slide‑out sieves reduce cleaning and maintenance time, improving operational uptime.

Performance Benefits

• Improved Purity: Multi‑stage cleaning consistently reduces foreign‑matter content, meeting stringent milling and brewing specifications.

• Uniform Grading: Size and density separation deliver homogeneous grain lots, enhancing process consistency in mills and breweries.

• Reduced Breakage: Gentle vibratory and air‑flow designs protect kernel integrity, preserving end‑product quality.

Typical Applications

• Wheat Milling: Clean, size‑graded wheat increases flour yield and quality.

• Barley Malting: Uniform kernels ensure even steeping and germination rates.

• Rice Processing: Removal of husk fragments and broken grains improves milling yield.

• Animal Feed: Graded cereals blend predictably for balanced nutrition.

Hebei Julite Sorting Technology Co., Ltd. provides turnkey support—from feasibility studies and civil works planning to commissioning, staff training, and preventive‑maintenance contracts—to guarantee long‑term reliability of each Grain Cleaning and Grading Machine.
