METHOD FOR DESINSECTION AND DISINFECTION OF MATERIALS OF GRAIN ORIGIN Russian patent published in 2008 - IPC A01C1/00 A23B9/04 A23L1/25 A23L3/01 H05B6/64 

FIELD: methods for pre-plant processing of grain.

SUBSTANCE: method includes creation of re-circulating gas stream in discharge chamber, injection of UHF energy, creation of plasma in chamber volume and letting material being processed through the chamber in form of free-falling stream. The UHF energy for creation of plasma is injected in impulse or in continuous modes in form of three electromagnetic waves, two of which have orthogonal linear polarization, which is perpendicular to the discharge chamber axis, and third wave has axial component of electromagnetic field, and the material is additionally affected by modulating at least one electromagnetic wave with impulses with frequency of repetition within ultrasonic spectrum. Duration of impulses equals 1-5 microseconds. Also, modulation frequency changes continuously in aforementioned ultrasonic spectrum with period of 0,01-0,02 seconds, and constant electric current is additionally let through plasma equipment.

EFFECT: prevented infection of grain by barn billbug, suppressed bactericide infectiousness and increased germination capacity of grain.
