Optimized Design for Efficient Air Separation

The vertical air duct adopts an optimized cross-sectional structure and flow path, which creates a stable and uniform airflow field. This allows precise separation of light impurities without excessive air loss. The adjustable air-regulating plate enables operators to fine-tune suction intensity according to the characteristics of different grains, ensuring consistent performance under varying working conditions.

The vertical air duct is typically installed after cleaning machines such as vibrating separators, destoners, and wheat scourers. It removes lightweight impurities and ensures that only pure grain enters the milling section. The machine is widely applied in wheat flour mills, corn flour mills, feed production lines, and seed cleaning plants.
