MMCTECH Pressure Type Destoner Machine – DSS-1000 Series
The MMCTECH Pressure Type Destoner Machine – DSS-1000 Series is a high-efficiency destoner separator designed to remove stones, glass, metal particles, sand, soil, mud balls, heavy impurities, and dense foreign materials from grains, seeds, pulses, oilseeds, spices, and specialty agricultural products. Built for professional seed processing plants, grain cleaning facilities, rice mills, pulse processing lines, oilseed cleaning operations, food ingredient plants, and turnkey agricultural processing systems, the DSS-1000 Series provides reliable stone removal performance using pressure airflow and vibration-based separation technology.
Stones and heavy impurities are among the most damaging contaminants in grain and seed processing. They can reduce final product quality, damage downstream equipment, increase maintenance costs, create food safety risks, and lower customer confidence. The MMCTECH DSS-1000 Series is engineered to solve this problem by separating products according to density difference. Clean product and heavy impurities move differently on the pressure vibrating deck, allowing stones and dense materials to discharge separately from the good product stream.
The working principle of the DSS-1000 Series is based on pressure airflow + vibrating deck separation + controlled product feeding. Product is fed evenly onto the vibrating deck by a linear vibratory feeder. The dual fan system creates controlled pressure airflow through the product layer. Lighter clean grains and seeds are lifted and fluidized by air, while stones, glass, metal pieces, soil clods, and other heavy impurities stay closer to the deck surface. The fixed speed eccentric motor creates the deck movement required to move heavy material toward the stone outlet while clean product flows toward the product outlet.
This pressure-type destoner is suitable for wheat, rice, barley, maize, oats, rye, sorghum, millet, quinoa, sesame seed, sunflower seed, soybean, flaxseed, mustard seed, canola, chickpeas, lentils, beans, peas, cumin, coriander, fennel, coffee beans, cocoa beans, garden seeds, vegetable seeds, oilseeds, pulses, cereal grains, and other free-flowing agricultural products. It can be used as a standalone stone removal machine or integrated into a complete MMCTECH processing line with seed cleaners, grain cleaners, screen graders, gravity separators, color sorters, conveyors, elevators, bagging scales, silos, dust collection systems, and automation control panels.
The DSS-1000 Series is especially important before color sorting, dehulling, milling, polishing, roasting, packaging, or seed treatment. A color sorter can remove visual defects, but stones and dense impurities should be removed mechanically before optical sorting whenever possible. A destoner also helps protect dehullers, mills, polishers, elevators, conveyors, and packaging equipment from damage caused by hard foreign materials. For food-grade and export-oriented processing, reliable destoning is one of the most important steps in final product preparation.
The machine is designed with a pressure vibrating deck, dual fan system with adjustable valves, linear vibratory feeder, fixed speed eccentric motor, and heavy duty steel construction. These features help provide stable product flow, adjustable air control, strong separation efficiency, and long-term industrial durability. The pressure airflow system allows operators to adjust the air according to product type, product density, impurity level, and desired separation accuracy.
The DSS-1000 Series provides a capacity range of 11,023–26,455 lbs/hour (5–12 metric tons/hour), depending on crop type, product condition, impurity level, moisture, airflow setting, deck adjustment, feed rate, and final cleaning target. The machine is suitable for medium and large processing facilities that need dependable destoning performance for multiple products. MMCTECH can evaluate the crop and separation requirement to recommend the correct destoner configuration, feeding system, outlet layout, dust collection connection, and processing line integration.
For rice and paddy processing, the pressure type destoner helps remove stones and dense impurities before polishing, color sorting, or packaging. For wheat and barley cleaning lines, it removes heavy contaminants that can damage milling and handling equipment. For pulses such as lentils, chickpeas, beans, and peas, it improves final product quality and export preparation. For oilseeds such as sesame, sunflower, canola, flaxseed, and mustard seed, it helps remove sand, stones, and heavy impurities before downstream cleaning, hulling, pressing, roasting, or packaging.
MMCTECH manufactures the DSS-1000 Series for North America and international markets. The machine can be configured for 208 / 240 / 480 / 600 VAC – 3 Phase – 50/60 Hz industrial electrical standards. MMCTECH can also support full project planning, plant layout, equipment selection, conveyor integration, dust collection design, PLC / SCADA automation support, and complete seed processing line engineering according to product type, capacity requirement, and final quality target.
