Abstract:According to the structure of squat silo, the characteristics of large grain heap and experience in the past 20 years, the characteristics of grain storage in squat silo were summarized. By utilizing favorable conditions for playing good thermal insulation of squat silos and complete facilities, improving the management mode during processing,the grain temperature in squat silo was controlled, therefore some problems,such as agglomeration, moisture condensation, grain hanging on the silo wall, were avoided to ensure the safety of grain storage in squat silo.
