“…Past studies have reported that the optimal selection of threshing rotational speed and the thresher-concave distance can increase the threshing Feeding rate, (kg•h -1 ) efficiency and also reduce the broken pod percentage simultaneously. These results are consistent with the results achieved in this study (Aboegela and Mourad, 2021;Senthilkumar et al, 2017;Srinivasan et al, 2021;Vennela et al, 2018).…”

“…According to initial experiments, it was found that at the rotational speed less than 50 rpm the tresher does not have a high ability to separate the seeds from the pod, although the percent of damaged seeds is low. According to previous studies, at a rotational speed greater than 100 rpm, threshers have a high ability to separate seeds from the pod, however the number of damaged seeds has also increased with increasing threshing speed (Aboegela and Mourad, 2021;Senthilkumar et al, 2017;Srinivasan et al, 2021;Vennela et al, 2018). Therefore, in this experiment, the thresher rotational speed was selected between 100 and 300 rpm to determine the optimal value of the thresher speed in combination with the feeding rate and the thresher-concave distance (Table 1).…”

“…It was found that increasing the rotational speed of the thresher and reducing the thresher-concave distance enhance the percentage of seeds damage. Vennela et al (2018) compared the performance of a stationary thresher working with the tractor's power take off (PTO) shaft with a manual pedal thresher. The results showed that increasing the threshing speed causes a higher threshing efficiency.…”

“…The results showed that increasing the threshing speed causes a higher threshing efficiency. The working capacity of the PTO power thresher was also found to be 4 times higher than that of the manual pedal thresher (Vennela et al, 2018). Aboegela and Mourad (2021) tested an experimental thresher to separate peanut seeds from pods using rasp, spike teeth, and knife threshers.…”

Peanut is an important produce in the global food chain because of their high-quality oil and protein content. Due to the significant value of its production in Iran, a threshing machine was developed for high-quality harvesting, to reduce harvesting costs and labor effort. In the course of a number of field experiments to evaluate the performance of the machine, the rotational speed of the thresher was adopted at three levels of 150, 200, and 300 rpm. Other experimental factors included the distance of the concave from the thresher (2, 6, and 8 cm) and the product feeding rate of 750, 850, and 950 kg·h−1. Regarding the measurements, the threshing efficiency, the separation rate, and the percentage of the crushed product were calculated and evaluated. The results revealed that as the rotational speed of the thresher, the increment feeding rate of the product and the distance between the thresher and the concave grate increased, the thresher efficiency decreased. The maximum threshing efficiency of 95% was obtained at a rotational speed of 150 rpm and a distance of 2 cm. Also, with increasing the rotational speed of 300 rpm and a distance of 8 cm, the threshing efficiency decreased to 75%. The separation rate decreased intensely as the distance between the thresher and the concave increased. In addition, the separation rate decreases with increasing rotational speed of the thresher. At a rotational speed of 150 rpm and a distance of 2 cm, the separation rate was 96%, but the separation rate decreased to 76% as rotational speed increased to 300 rpm and distance increased to 8 cm. With increasing rotational speed and feeding rate, the percentage of crushed pods increased. The maximum of 16% was obtained at a rotational speed of 300 rpm, a feeding rate of 950 kg·h−1 and a distance of 2 cm.

“…Sorghum threshing was given at the 21 m/s cylinder speed, 10 mm Drum concave clearance, and 590 kg/h feed rates. Vennela et al (2018) crop parameters observed during threshing were plant height was 35.68 cm with the average number of filled pods of 20.04 per plant and average the pod-vine ratio was noted as 1:4 for the K6 variety of groundnut. It was observed that at the feed rate of 870 kg h -1 the thresher output capacity was 227.25 kg h-1 with a total number of labors of 6.…”

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. 7%) 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.
