The movement of grains during drying generates a significant amount of dust. To contain emissions, our fixed dryers feature specific solutions: the movement of the product takes place over very concentrated time periods to limit dust dispersion during loading and unloading phases. The airflow is interrupted during the phases of greatest product movement, when dust is most likely to form, in order to reduce its dispersion. the suction system includes an optional device that captures dust, concentrates it, and directs it to collection systems before releasing it into the air.
