AI Technical Summary
During grain screening, impurities tend to move to the top of the grain, and the grain is prone to clumping when it gets damp, increasing the difficulty of screening. Existing technologies are unable to effectively remove impurities and maintain screening efficiency.
Dehumidification is achieved by combining an electric heating grid and a fan inside the conveying pipe, and the grain residence time is controlled by a screw conveyor. Impurities are removed by the vibration of the screen and an auxiliary dust collection mechanism, and the screening path is optimized by a guide plate.
It effectively reduces the impact of grain moisture, improves screening efficiency, ensures the removal of impurities, and avoids grain accumulation that could affect screening results.
