MMCTECH Vibration Type Destoner Machine – DSV-1000 Series
The MMCTECH Vibration Type Destoner Machine – DSV-1000 Series is a high-efficiency seed stone separator designed to remove stones, glass, metal fragments, sand, soil clods, heavy particles, and dense impurities from grains, seeds, pulses, oilseeds, and specialty agricultural products. Built for modern seed cleaning plants, grain processing facilities, sesame cleaning lines, sunflower seed processing plants, pulse cleaning operations, food-grade processing facilities, and turnkey seed processing systems, the DSV-1000 Series provides reliable stone removal performance with vibration-based separation, controlled airflow, adjustable deck settings, and multi-screen destoning technology.
Stone removal is one of the most important stages in grain and seed processing. Stones, glass, metal pieces, and other dense impurities can damage downstream equipment, reduce product quality, increase maintenance cost, create food safety concerns, and lower final product value. The MMCTECH DSV-1000 Series is engineered to remove these heavy contaminants before product moves to color sorting, gravity separation, dehulling, milling, polishing, roasting, treating, bagging, or packaging.
The working principle of the DSV-1000 Series is based on vibration + controlled airflow + density separation. Product is distributed onto the vibrating deck and screen area. Airflow helps stratify the product layer by density, allowing lighter clean product to move separately from heavier contaminants. Stones and dense impurities remain closer to the deck and are guided toward the reject outlet, while clean grains and seeds move toward the clean product outlet. Adjustable deck settings and airflow control allow the operator to tune the machine according to crop type, product density, impurity level, moisture, and desired separation accuracy.
The DSV-1000 Series is suitable for wheat, sesame seed, sunflower seed, pulses, rice, paddy, barley, maize, corn, oats, rye, sorghum, millet, chickpeas, lentils, beans, peas, soybeans, flaxseed, linseed, mustard seed, canola, cumin, coriander, fennel, coffee beans, cocoa beans, garden seeds, vegetable seeds, oilseeds, cereal grains, spices, and many other free-flowing agricultural products. It can be used as a standalone destoner machine or integrated into a complete MMCTECH processing line with seed cleaners, grain cleaners, screen graders, gravity separators, color sorters, conveyors, elevators, dust collection systems, bagging scales, silos, and automation control panels.
Compared with basic stone separation equipment, the MMCTECH DSV-1000 Series provides an industrial destoning structure with two screens, rubber ball screen cleaning, high aspirator air volume, separate aspirator motor configurations for heavy and light products, table setting motor, dual vibro motors, and manual or PLC-actuated seed inlet settings. This makes the machine suitable for facilities that process multiple crops and need stable destoning performance across different product densities.
The DSV-1000 Series is especially useful for sesame seed and sunflower seed processing because these products can be affected by stones, sand, soil particles, and dense impurities during harvesting and handling. The machine’s vibration deck and controlled airflow allow delicate products to be separated more carefully while maintaining product quality. For wheat and cereal grains, the DSV-1000 Series helps protect milling, dehulling, cleaning, conveying, and packaging equipment from damage caused by hard contaminants.
The machine provides listed capacity up to 22,000 lbs/hour (11 short tons/hour) on wheat with 47.4 lb/cu ft bulk density, 17,600 lbs/hour (8.8 short tons/hour) on sesame with 37.5 lb/cu ft bulk density, and 11,600 lbs/hour (5.8 short tons/hour) on sunflower seed with 21.8 lb/cu ft bulk density. Actual capacity depends on product type, bulk density, moisture level, stone content, impurity level, airflow setting, deck adjustment, feed rate, and processing target.
The DSV-1000 Series is designed with a 32.3 sq ft screening area, two screens, 48 x 50 in screen size, rubber ball screen cleaning system, heavy product aspirator motor, light product aspirator motor, table setting motor, dual vibro motors, and ST44 / birch wood construction. The machine supports North America and international electrical requirements and can be configured for 208 / 240 / 480 / 600 VAC – 3 Phase – 50/60 Hz, with standard voltage reference of 460 V depending on project configuration.
For facilities that require automation, the seed inlet settings can be supplied with manual adjustment or actuator control with PLC model configuration. MMCTECH can support conveyor integration, dust collection connection, electrical planning, automation control, layout design, and complete processing line engineering. This makes the DSV-1000 Series suitable for both standalone destoning applications and complete MMCTECH automation-supported grain and seed processing plants.

Frequently Asked Questions
What is the best machine for removing stones from seeds and grains?
The best machine for removing stones, glass, metal fragments, sand, and heavy impurities from seeds and grains is usually a destoner machine. The MMCTECH DSV-1000 Series uses vibration-based separation, controlled airflow, and adjustable deck settings to separate heavy impurities from clean product.
What is a vibration type destoner?
A vibration type destoner is a seed stone separator that uses a vibrating deck and airflow to separate dense impurities from lighter grains or seeds. Stones remain closer to the deck while clean product moves separately through the machine.
How does a vibration type destoner work?
Product is distributed onto the vibrating deck. Controlled airflow stratifies the product layer by density. Stones and heavy impurities stay lower on the deck and move toward the reject outlet, while clean product exits through the clean product outlet.
What is the working principle of a destoner?
The working principle of a destoner is density separation using airflow and deck movement. Airflow lifts or fluidizes lighter product, while heavier impurities such as stones, glass, metal, and soil clods remain lower and are discharged separately.
What is the function of a seed stone separator?
The function of a seed stone separator is to remove stones and dense impurities from seed lots before final grading, color sorting, treating, bagging, packaging, or storage. This improves product quality and protects downstream equipment.
Do I need a vibration type destoner or pressure type destoner?
The correct destoner depends on product type, capacity, density difference, impurity level, facility layout, and desired separation performance. A vibration type destoner is suitable for many grains, pulses, oilseeds, sesame, sunflower, and specialty products. MMCTECH can evaluate the product and recommend the correct machine.
Do I need a destoner, gravity separator, color sorter, or seed cleaner?
Each machine performs a different function. A seed cleaner removes general impurities, a destoner removes stones and heavy impurities, a gravity separator separates by density, and a color sorter removes visual defects. Many professional processing lines use these machines together.
