| Abstract | ||||
| A threshing process for peanut crop is considered one of the most essential agricultural operations. Therefore, the research aimed to develop a local threshing machine for separating and extracting the peanut pods from straw and other materials. This was done by replacing the normal concave with a new one with opening of 7×7cm per opening (square shape). The front sieve is replaced with its last holes in the form of slides, with a distance of 0.5 cm. And adjusting the clearance between the threshing drum and concave in range of 7cm for drum-type (1) and the clearance between the threshing drum and concave should be 5cm for drum-type (2), The experimental work was carried out at El Delengat district, Behera Governorate. The performance of the thresher was tested under three crop feeding rates of 15, 20, and 25 kg/min, meanwhile, four speeds for a threshing drum 300, 350, 400, and 450 rpm (10.99, 12.82, 14.65, and 16.48m/s) and two types of threshing drums were tested, drum-type (1) 44 knives with a concave clearance 7cm and drum-type (2) 22 knives with a concave clearance 5cm. The results conducted that, the highest threshing efficiency (99.47%) was obtained by drum type (2) under 450 rpm drum speed and 15kg/min feeding rate. The modified drum type (2) showed the lowest broken pods with an average of 1.93%. The lowest required power (12.2 kW) was shown under 300 rpm drum speed and 15 kg/min feeding rate. | ||||
