Abstract

In this research the effects of drum speed and feed rate on the amount of WHEAT GRAIN damages during THRESHING operation were investigated. A local flail type THRESHING machine for THRESHING wheat at three different drum speeds (11, 20 and 36.7 m s-1) and at three different feed rates (0.013, 0.025 and 0.05 kg s-1) was used. Increasing drum peripheral speed from 11 to 20 m s-1 has been resulted in increasing visible and invisible damages from 0.01% to 1.95% and from 2.13% to 16.5%, respectively. Increasing drum peripheral speed up to 36.7 m/s the visible and invisible damages observed as 24.3% and 36.85%, respectively. On the other hand, increasing the machine feed rate from 0.013 to 0.025 kg s-1 and then to 0.05 kg s-1, the percent of broken seeds were decreased by 21.17% and 31.8%, respectively. The germination test showed that the both type of germinations (visible and propositional) decreased with increasing drum speed and increased with increasing feed rate. The electrical conductivity of the threshed seeds had a direct relationship with increasing the drum speed and decreasing the feed rate. The Slids10 and Sohag10 varieties were the toughest and the most weakened varieties, respectively in this investigation.
