Yellowing is one of the significant factors of grain loss.This study provides a basis for warehouse design by comparing the effects of different warehouse types.This study constructs geometric models of various silo types in Nanchang region,using local environmental temperature,humidity and solar radiation irradiance as boundary conditions to simulate and compare the temperature distribution,water distribution and yellowing distribution of silo types in Nanchang region under different height-diameter ratio(ratio of grain height to diameter).The results indicate that the weight of external influence on grain piles with different height-diameter ratios is different in different directions.When the height-diameter ratio is 1.0,the overall yellowing degree of the grain pile is minimized,making it more suitable for rice storage.
