Abstract

In this research, a novel concave–convex vibrating screen design was developed and optimized to enhance the cleaning efficiency of fuzzy cottonseed prior to the oil extraction process. The study focused on improving the mechanical and dynamic characteristics of the screening surface by introducing sinusoidal and cosinusoidal wave profiles in the transverse and longitudinal directions, respectively. The physical and mechanical properties of locally grown cottonseed varieties in the Namangan region were analyzed to determine optimal design parameters such as inclination angle, vibration frequency, amplitude, and aperture geometry. Analytical modeling established that the optimal inclination angle for uniform seed distribution is 30°, with an amplitude of 4 mm and a vibration frequency corresponding to an eccentric shaft speed of 200 rpm. Under these parameters, the cleaning efficiency reached 88%, representing a 12–15% improvement compared to the conventional flat-screen design. The proposed screen geometry facilitated uniform seed flow, reduced clogging of fine apertures, and ensured continuous stratification of impurities through multi-directional oscillations. The theoretical model, supported by experimental observations, confirmed that the modified harmonic surface enhances dynamic particle movement, thereby improving overall sorting performance and energy efficiency.
