MMCTECH Double Deck Seed Grader Machine – Classic SG-002 Series
The MMCTECH SG-002 Double Deck Seed Grader Machine is a reliable and economical seed grading solution designed for agricultural processing facilities, seed conditioning plants, grain cleaning operations, pulse processing facilities, and commercial farming businesses. As part of the MMCTECH Classic Series, this machine combines proven screening technology with a durable double deck structure to efficiently separate products according to size, thickness, and grading requirements.
Designed for seed grading, grain sizing, and product classification, the SG-002 Series helps processors improve product uniformity, market value, and final product quality. The machine is suitable for wheat, barley, oats, corn, soybean, sunflower seed, sesame seed, rice, canola, lentils, peas, chickpeas, beans, grass seed, vegetable seed, flower seed, and many specialty agricultural products.
The double deck screening design allows multiple grading fractions to be produced in a single pass. Products are distributed evenly across the screen surfaces where carefully selected perforated screens separate oversize, marketable product, and undersize material. This grading process improves product consistency and increases downstream processing efficiency.
The SG-002 utilizes a mechanical vibratory screening system that delivers stable product movement across the screens. Integrated screen cleaning brushes help maintain screen efficiency by preventing blockage and ensuring continuous grading performance. This feature is particularly important when processing products that contain dust, broken material, or varying moisture conditions.
As an economical grading machine, the Classic SG-002 Series remains a popular choice for facilities seeking dependable performance without the complexity of larger industrial systems. The machine is frequently installed after pre-cleaning equipment and before gravity separators, color sorters, seed treaters, bagging systems, or packaging lines.
The machine supports seed cleaning and grading operations where accurate product sizing is essential for market acceptance, export requirements, planting quality, and processing consistency. Uniform product size improves seed treatment coverage, packaging accuracy, gravity separation efficiency, and optical sorting performance.
