| Abstract | ||||
| Combined equipment for seed separation and for chopping of sunflower heads was designed, locally manufactured, and evaluated. It performs many functional processes namely: scrubbing sunflower heads for seed separation, seed releasing and collecting, and chopping sunflower heads and other crop materials. The performance of that equipment has been tested versus different design and operating parameters. Performance evaluation of the fabricated equipment has been done in terms of equipment productivity seed damage seed cleaning efficiency uniformity of head chopping, and power unit required for accomplishing all processes. The results of this study showed that using the designed equipment for cutting sunflower heads can used with high performance productivity of 189.08 kg/h at 21.4% d.b moisture content and at the cutting drum tip speed of 34.01 m/s when lengths of neck with heads of 25 cm. Whereas, the higher distribution percentage was 89 for cutting width distribution range of 2.5-4 cm at length of stalks with heads 10 cm when the moisture content was 10.5% d.b at cutting drums speed of 28.78 m/s. At increasing cutting drum tip speed from 15.69 m/s to 34.01 m/s at moisture content of 21.4% d.b and length of neck with heads of 10 cm, the energy consumption increases with about 23%. | ||||
