Ultra Double Deck Trieur is a high-performance grading and separation machine designed for precise removal of broken wheat, weed seeds, and other small foreign materials from grain in flour mills and seed cleaning plants.The machine consists of single or double deck indented cylinders rotating in motion, combined with an internal screw (auger) system placed inside the cylinders. Thanks to its two-stage operating structure, the product is first fed onto the pressed section of the cylindrical indented sheet. Broken and short kernels that settle into the surface pockets are guided by the screw conveyor into the collection chamber and discharged from the system.In the second stage, the grain is processed on a surface with smaller-diameter indentations, allowing effective separation of longer kernels. The cylinder inclination angles and the opening of the collection trough can be mechanically adjusted, enabling easy adaptation to different grain types and capacity requirements.Powered by a geared motor and belt-pulley drive system, the Ultra Double Deck Trieur operates quietly and with minimal vibration. Its high separation accuracy improves the quality of grain entering the milling process, extends machine lifespan, and increases overall production efficiency. It is a reliable, sales-driven solution for modern milling facilities.
