DEVICE FOR SEPARATION OF SEEDS IN ELECTROSTATIC HIGH-STRENGTH FIELD Russian patent published in 2001 - IPC

FIELD: farming; separation and sorting-out of loose materials in electrostatic field. SUBSTANCE: proposed device includes two electrodes: one electrode-sieve is grounded and other electrode is made from dielectric; voltage from high-voltage source is fed to this electrode on its rear side; additional electrode is mounted under sieve; this electrode is also made from dielectric at dielectric permittivity higher than that of main dielectric electrode. EFFECT: improved separation of seeds. 1 dwg
