Development of a Novel Dielectric Seed Cleaner Controlled by Microcomputer

In this paper, a new design of the dielectric selecting machine of seeds, as well as its selecting process and microcomputer control method, were described. The new designed machine is used in selecting high quality seeds of grains and vegetables and improving their germinative ratio. It makes use of the dielectric characters of seeds with different physical and mechanical properties to separate off the seeds with different vitalities. The control system of the machine including the hardware and the software was also developed. The machine has the features of stable performance, simple operation and high quality of seed selection.
