Abstract
This paper examines methods for sorting tomato seeds using electrical (electrostatic and triboelectric) sorting devices. It analyzes the potential for separating seeds based on density, mass, dielectric permittivity, and moisture content under the influence of a high-voltage electric field. Research results indicate that the electrical sorting method increases seed germination by 18–25% compared to traditional mechanical and aerodynamic methods, raises the proportion of high-quality seeds to 90–95%, and reduces energy consumption. The optimal operating parameters for the device—voltage of 750–1500 V, drum rotation speed of 40–60 min⁻¹, and electrode spacing of 3–5 mm—are substantiated. The paper presents the sequence of methods, graphical analyses, comparative results, and conclusions.
