The Medium-Blocking Discharge Vibration-Uniform Material Plasma Seed Treatment Device Based on EDEM

Pre-sowing treatment of seeds by plasma can improve seed vigor and promote germination growth. To solve the problems low processing volume uneven in devices, according to process scheme medium-blocking discharge treatment, a vibration-uniform material device was designed, structure working principle were systematically analyzed, mathematical model force established. According electromagnetic vibration theory, sorting conveying principles analyzed lower trough, relevant parameters selected calculated. Using EDEM discrete element simulation software, numerical alfalfa feeding carried out. A three-factor, three-level orthogonal test The results showed that amplitude groove shape significantly affected coefficient variation uniformity on during processes, wheel speed had certain effect uniformity. main order factors affecting spreading B > notch C A. optimal 35 r/min, circular, 0.55 mm.
