Abstract

In order to solve the poor pelleting quality of Agropyron seeds, this paper designs a novel pelleting experimental platform. A regression mathematical model of pelleting qualified rate and single seed rate was established and analysed by variance. The results showed that vibration had significant effect on pelleting quality. The order of influence is as follows: rotating speed>vibration frequency> tilt angle of coater. When the speed is 41.7 r/min, the vibration frequency is 20.28 Hz, and the tilt angle is 34.89 °, the pelleting qualified rate and the single seed rate are the highest, 83.1% and 94.9% respectively.
