Problems solved by technology

At present, cold plasma seed treatment equipment can only process small-grained seeds, such as rice seeds, wheat seeds, etc., and cannot modify larger-grained seeds above peanuts, especially seedlings (such as American red oak) and traditional Chinese medicine. medium and large grain seeds
Increasing the distance between the discharge plates is the only feasible way to treat medium and large particles in cold plasma, but this reduces the photon density of cold plasma
Vacuum ultraviolet (VUV) region in glow discharge in a low vacuum state ≤ 1800 A) radiation plays a decisive role in the modification of seeds, so a certai

Abstract

The invention relates to equipment for performing modified treatment on medium and large particle seeds by using cold plasma. The equipment comprises a charging barrel, a discharging barrel, and a vacuum cavity connected with the charging barrel and the discharging barrel, wherein an air exhaust is formed in the vacuum cavity and is connected with a mechanical pump; a discharge treatment device and a transfer device are arranged in the vacuum cavity; the discharge treatment device comprises two polar plates arranged in parallel and a discharge treatment radio-frequency power supply connected with the two polar plates; the distance between the two polar plates is 30-40mm; a preionization device is arranged in the vacuum cavity and comprises an electrode and a preionization radio-frequency power supply connected with the electrode; and the vacuum cavity is connected with an earth phase. According to the equipment disclosed by the invention, the preionization device is arranged in the vacuum cavity, so that the working power supply can instantaneously build up luminance, and the time needed by processing is accurately controlled; with the adoption of ionization dust removal, the working space is clean; and moreover, large-scale treatment of medium and large particle seeds with the particle size of more than 15mm can be realized under the condition that the mature process parameters are guaranteed.
