Technological line for presowing seeds treatment in the high frequency corona discharge field
In article the analysis of the modern equipment for preseeding and postharvest processing of crops seeds has been conducted. Expediency of development and application of electrotechnological installations for processing of seeds by pulse crown categories on the basis of the conducted analysis is proved Maximum efficiency of plasmochemical reactions of formation of ozone due to use of pulse crown categories can be received. Safety of labor at service of installation increases use of high-frequency categories. It allows to reduce the sizes of the voltage pulse generator. The technological scheme of the line for preseeding processing of grain is offered by authors of article. The main advantage of this treatment method is the absence of supplies, since ozone is generated directly from the air. It allows to automate as much as possible processing and storages of sowing material. Lack of expendables is the main advantage of this way of processing because ozone is generated directly from atmospheric air. By mathematical modeling of distribution of electric field strength in volume of the discharching chamber the design of the discharching chamber is developed. It provides rectangular distribution of electric field strength on all volume of the chamber. Recommendations about optimization of a design of the recharching chamber as a result of the numerical analysis of characteristics of electric field have been offered. Due to use of a corona-forming electrode with microledges creating favorable conditions of crown formation categories at smaller values of voltage of a crown has been reached. Application of installations for preseeding and postharvest seed treatment of agricultural production is able to afford to refuse fumigation and to achieve increase in productivity and increase in energy of germination of crops. Results of work confirm prospects of use of high-frequency pulse voltage generators in electrotechnological installations for preseeding and post-harvest seeds treatment.
