The Destoner is engineered and manufactured in multiple models with working widths of 80, 100, 125, 150, and 200 cm. Its primary function is the precise separation of heavy, same-size impurities—such as stones, pebbles, metallic particles, and soil clods—from paddy, brown/white rice, and other grains. Operating Principle: The separation process relies on the difference in specific gravity (bulk density) between the grain and heavy foreign materials. By combining the multidirectional oscillation of the patterned screen deck with an upward air stream (fluidized bed principle), lighter grains are fluidly suspended on an air cushion and conveyed toward the clean product discharge. Simultaneously, denser stones and heavy contaminants remain in contact with the screen mesh and are propelled upward in the opposite direction toward the reject outlet. Key Features & Advantages: • Exceptional Efficiency: Outstanding precision in eliminating impurities and stones identical in size to the grain. 5 • Wear-Resistant Screens: Fitted with high-durability perforated plates with optimized inclination angles and oscillation kinematics. • Accurate Airflow Control: Sensitive aspiration/blower regulation to accommodate various types of grains and moisture levels. • Smooth & Dust-Free Operation: Low-vibration continuous processing with an integrated, sealed dust-containment design. • Low Maintenance & High Energy Efficiency: Minimal operational costs with optimized power consumption.
