Desin and Simulation of Seed Distributer for the Vacuum Low-temperature Plasma Seed Processing Equipment Base on EDEM

Abstract. Low-temperature plasma (LTP) is a high-energy state of the material gathered, Plasma seed processing technology is the use of high energy aggregation on treating seeds. The LTP stimulation could improve seed germination. Conveyor belt was used in vacuum low-temperature plasma seed processing equipment to transmit seeds to be treated. The thickness of the seeds on conveyor belt directly affects the uniformity of seeds processed, because too much seeds will cause that the underlying layer of seeds can't contact with plasma. Then it can lead to uneven effect of seed germination to adverse the mechanization of production. Therefore, it is important to design structure of seed distributer to ensure the seeds can be evenly distributed on the conveyor belt. Lastly, simulation analysis was carried on the seed distributer.
