CLOSED CIRCUIT RADIAL TARAR is a high-efficiency pre-cleaning machine developed for flour and semolina mills as well as seed cleaning plants to separate low-density and aerodynamically different foreign materials from grain. Grain fed from the inlet unit is evenly distributed across the full width of the machine and directed into a horizontal air channel. Within this section, a controlled airflow effectively removes straw, trash, husk fragments, light shells, dust, and similar impurities, discharging them from the system. The dual, adjustable wall design allows precise control of air velocity and direction, ensuring optimal cleaning performance for different grain types and capacity requirements. Thanks to its closed-circuit design, dust emissions to the external environment are prevented, plant hygiene is improved, and energy loss is kept to a minimum. The robust steel construction is designed for long-term, vibration-free operation. By ensuring grain is cleaned to the highest possible level before entering the milling process, the Closed Circuit Radial Tarar extends machine lifespan and significantly improves the quality of flour and semolina. With high efficiency, low maintenance requirements, and an environmentally friendly operating principle, it is an essential solution for modern milling facilities.
