MMCTECH Single Deck Seed Grader Machine – Classic SG-001 Series
The MMCTECH Single Deck Seed Grader Machine – Classic SG-001 Series is a compact, efficient, and reliable seed grading machine designed for precise two-size classification of seeds, grains, pulses, legumes, oilseeds, garden seeds, spice seeds, and specialty agricultural products. Built for seed processing plants, grain cleaning facilities, pulse processing operations, agricultural cooperatives, food processors, export preparation facilities, and commercial seed conditioning lines, the SG-001 Series provides consistent grading quality with a simple and durable single deck screening system.
As part of the MMCTECH Classic Seed Grader Series, the SG-001 is engineered for operations that need accurate product sizing without unnecessary complexity. The machine separates seeds and grains into two fractions by using a vibratory screening principle. Product is fed onto the single screen surface, evenly distributed by controlled vibration, and separated according to screen perforation size. Smaller material passes through the screen while larger material continues toward the discharge outlet. This process supports cleaner product appearance, improved uniformity, better packaging quality, and more efficient downstream processing.
Uniform seed size is a critical factor in modern agricultural processing. For seed producers, consistent sizing can improve seed treatment coverage, planting performance, and germination uniformity. For grain and pulse processors, grading helps remove broken pieces, underdeveloped kernels, split grains, and size-inconsistent material before final packaging, storage, shipment, or further processing. The MMCTECH SG-001 helps facilities improve product value by creating a more uniform and market-ready output.
The SG-001 Series is ideal for products such as soybeans, chickpeas, lentils, dry beans, kidney beans, sesame seeds, sunflower seeds, wheat, rice, corn, sorghum, millet, oats, barley, grass seeds, vegetable seeds, garden seeds, spice seeds, and other specialty crops. It can be used as a standalone screen seed grader or integrated into a complete MMCTECH seed cleaning and grading line with pre-cleaners, fine cleaners, gravity separators, destoners, color sorters, seed treaters, conveyors, bagging scales, and automation systems.
One of the most important features of the MMCTECH SG-001 is its brush-assisted screen cleaning system. During operation, brushes help keep screen perforations open and reduce clogging caused by dust, broken pieces, lightweight materials, or irregular product shapes. This improves grading consistency, reduces downtime, and helps maintain stable production flow during continuous operation. For facilities processing products such as sesame, lentils, rice, cumin, sunflower, chickpeas, beans, or small specialty seeds, automatic brush cleaning is especially valuable for maintaining screen efficiency.
The SG-001 is commonly used before or after optical color sorting systems. When installed before a color sorter, the machine helps create a more uniform product layer, which can improve color sorting accuracy and reduce unnecessary load on the sorting machine. When installed after a color sorter, it can serve as a final quality grading step before packaging or bagging. This makes the SG-001 a practical solution for processors looking for a commercial seed cleaner, vibratory seed sorter, soybean grading machine, pulse sorting machine, or compact grain grading machine.
MMCTECH manufactures the SG-001 for North America and international markets with electrical compatibility for modern industrial processing facilities. The machine can be configured for 208 / 240 / 480 / 600 VAC, 3 Phase, 50/60 Hz electrical standards. Its compact design allows easy placement into existing processing lines, while its rugged construction supports long-term operation in demanding agricultural environments.

Where the SG-001 Is Used in a Seed Processing Line
The MMCTECH SG-001 can be used in several positions within a processing plant. It can be installed after pre-cleaning to classify product before fine cleaning or gravity separation. It can also be used before color sorting to improve product flow and optical sorting accuracy. In many facilities, it is used after color sorting as a final grading machine before packaging. This flexibility makes it a valuable part of complete agricultural seed processing equipment lines.
