        As global demand for coffee beans continues to rise year by year, many processing plants are facing severe challenges. Raw green coffee from origin countries—especially major producers like Ethiopia—often contains impurities such as unripe beans, insect-damaged beans, moldy beans, and stones. Traditional, manual processing is labor-intensive, time-consuming, and struggles to maintain consistent quality across batches.



 
        So, how can you configure a green coffee cleaning and grading line to achieve the perfect balance between high capacity and premium quality?

        The answer lies in a highly logical and seamlessly integrated process flow. Drawing on years of experience serving global coffee processing clients, Win Tone has developed a comprehensive Green Coffee Cleaning, Grading, and Color Sorting Production Line.


 
        Currently the most practical and widely adopted solution in Ethiopia, this system covers the entire lifecycle of green coffee processing:
        Pre-Cleaner: Efficiently removes large impurities, twigs, and dust to ensure the safe and smooth operation of downstream equipment.


 
        Destoner: Utilizes specific gravity differences to precisely remove stones of similar size (co-pitchers) and other heavy foreign materials.


 
        Grading Sieve: Accurately classifies beans by size, ensuring uniform specifications within each batch.


 
        Gravity Table: Separates inferior particles, such as unripe, insect-damaged, and shriveled beans, based on density differences.


 
        AI Optical Color Sorter: Equipped with advanced AI visual algorithms to accurately identify and reject discolored beans, moldy beans, and micro-defects.


 
        This well-designed, smoothly operating, and highly stable green coffee cleaning and grading line is Win Tone’s "Golden Combination" for coffee processors. It significantly increases the yield of premium beans while drastically reducing labor costs, and has already been successfully implemented in numerous facilities across Ethiopia.


 
        Whether you need to adapt to specific workshop layouts, handle complex raw materials, or meet ambitious capacity targets, Win Tone offers customized coffee processing solutions tailored to your exact production needs.
