Abstract
The experiment was conducted to evaluate the performance efficiency of seed cleaning and grading mobile factory for two varieties of wheat during summer season from 1/7 - 1/9/2007. Three factors were used in this study, the first one represented the variety of wheat including two varieties (Tbaa 99 and Sham 6), the second factor represented speeds of indented cylinder including three levels (0.57, 0.83, 1.05) m/sec, and the third factor represented angles of collecting trough including three degrees (60, 90, 120(. The characteristics studied in this study were grading efficiency, percent of loss of seeds and specific energy. The study used the completely randomized design and least significant differences of means test at level 0.05.The results were: 1- The seed variety of sham 6 was surpassed for record greatest values for grading efficiency and also recording significant lower in percent of loss and specific energy. 2- The speed of 0.57m/s recording lowest energy. While the speed of 0.83 m/s surpassed significant to record higher grading efficiency and lowest percent of loss. 3- The angle of 120 degree was surpassed for record greatest values for grading efficient and it has recorded lowest values in the percent of loss and specific energy. 4- The interaction between variety sham 6, speed of 0.83 m/s and angle of 120 degree was surpassed for record higher grading efficiency and lower percent of loss with specific energy. 5- There is a negative significant regression between the speed of indented cylinder and grading efficiency. Also a negative significant regression between the angle of trough and percent of loss was found.
