Pepper is one of Indonesia's leading agricultural products. However, post-harvest handling of pepper, such as the threshing process, is still done traditionally. Efforts to overcome these problems done by developing a mechanical threshing process, including by designing and construction a mesh thresher cylinder type of pepper threshing. Test results show, this pepper thresher has a weakness, namely low threshing efficiency so that it needs to developed. Based on these conditions, research is needed that aims to develop, modify and done performance tests on the pepper thresher. The modification was made by making the contact angle between the thresher cylinder and the threshing net is 60o and resulted length of the threshing contact field of about 5.23 cm. The independent variable was the thresher cylinder rotational speed varied into 540, 471, 451 and 352 rpm. The dependent variables were capacity, threshing efficiency and percentage pepper of damage. The results of the analysis showed that the rotational speed of the threshing mechanism had a very significant effect on the capacity, threshing efficiency and the percentage pepper of damage. Increasing the speed of the thresher cylinder can increase the capacity and percentage of damaged pepper, but reduce threshing efficiency. The threshing efficiency increase of the pepper thresher before and after modification was from 35.8% to 95.93% on the approaching treatment.

HighlightsAn efficient method for separating peanut seedlings and residual film harvested from film-mulched peanut was proposed, and the mechanism was optimized.The relationships between the suspension velocity and moisture content of different shredded materials were studied.Four-factor, three-level Box-Behnken experiments were carried out and analyzed, and the optimal parameter combination was determined.A validation test was carried out to verify the rationality and accuracy of the optimized regression model.Abstract. To address the problems of lower residual film removal and higher material loss in the forage utilization of peanut seedlings wrapped in residual film, this study explored the relationships between the suspension velocity and moisture content of different shredded materials derived from peanut seedlings and conducted performance tests and parameter optimization for a machine that uses peanut seedlings as forage material. Four-factor, three-level Box-Behnken experiments were designed using the rotational speeds of the shredding shaft, upper fans, and lower fans and the frequency of the vibrating sieve as test factors, and using the residual film removal rate and material loss rate as response values. The test results indicated that the suspension velocity of the shredded materials showed a quadratic relationship with moisture content. The performance tests showed that the significance sequence of the test factors for the residual film removal rate was: rotational speed of the lower fans, rotational speed of the upper fans, rotational speed of the shredding shaft, and frequency of the vibrating sieve. The significance sequence for the material loss rate was: rotational speed of the lower fans, rotational speed of the shredding shaft, frequency of the vibrating sieve, and rotational speed of the upper fans. The parameter optimization and validation test showed that the residual film removal rate was 92.71% and the material loss rate was 8.19% when the rotational speeds of the shredding shaft, upper fans, and lower fans were 1650, 770, and 665 rpm, respectively, and the frequency of the vibrating sieve was 4 Hz. The relative errors between the validation test results and the predicted values from the regression models were less than 3%, which suggests that the regression models are reliable. This study provides a reference for the forage utilization of peanut seedlings harvested from film-mulched peanut and provides a reference for determining the optimal working parameters of forage processing machines.
