5-Step Grain Cleaning Systems: Remove Impurities Efficiently

　　Grain quality directly affects food safety, storage stability, and processing yield. To ensure the highest standards, China Win Tone Machinery offers advanced 5-step grain cleaning systems designed to efficiently remove dust, stones, husks, and other impurities. With more than 30 years of expertise in grain processing technology, our solutions help millers and processors achieve cleaner, safer, and higher-value grains.

　　Step 1: Pre-Cleaning – Removing Large Impurities

　　The first stage targets larger foreign materials such as straw, sticks, and oversized particles. Using vibrating sieves and scalpers, the grain is prepared for deeper cleaning.

　　Step 2: Fine Cleaning – Eliminating Dust and Small Particles

　　High-efficiency aspiration channels and air cleaners remove dust, sand, and fine impurities. This not only improves grain purity but also ensures better working conditions in the facility.

　　Step 3: Destoning – Separating Stones and Heavy Impurities

　　Gravity-based destoners separate heavier impurities such as stones and clods that are similar in size to the grains. This step is critical for protecting downstream processing equipment.

　　Step 4: Magnetic Separation – Removing Metal Fragments

　　Magnetic separators efficiently remove ferrous metals and other harmful particles, ensuring the grain is free from hazardous contaminants.

　　Step 5: Grading and Sorting – Ensuring Uniform Quality

　　Finally, the grains are graded by size and weight. Color sorters can also be integrated to remove discolored or damaged kernels, delivering premium-grade output.
