Abstract

Highlights An efficient method for separating peanut seedlings and the 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 of peanut seedlings was studied. Four-factor and three-horizontal Box-Behnken experiments were carried out and analyzed based on Design-Expert 8.0.6 software, and the optimal parameters combination was determined. A validation test was carried out to verify the rationality and accuracy of the optimized regression model. Abstract. To address the current problems of lower residual film removal rate and higher material loss rate in the forage utilizing process of peanut seedlings wrapped in residual film, this paper studied the relationships between the suspension velocity and moisture content of different shredded materials derived from peanut seedlings, and conducted performance test and parameters optimization for the 9HRC-100 machine that utilizes peanut seedling as forage materials (hereinafter referred to as the machine). Four-factor and three-horizontal Box-Behnken experiments were designed by taking the rotational speeds of the shredding shaft, upper fans, lower fans and frequency of the vibrating sieve as test factors, taking 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
