Development and justification of parameters of a microwave installation for pre-planting treatment of vegetable seeds

Abstract

The article is devoted to the analysis of the dielectric parameters of potato and onion tubers for the development of a microwave installation that provides pre-planting treatment by means of a complex effect of electrophysical factors. The sources of energy were magnetrons, Ultratone or Darsonval. The originality of the research includes analysis of the volume of planting material for determination of the required plant performance; analysis of the dielectric parameters of potatoes depending on the frequency of EMF, humidity, and temperature for calculating the power of dielectric losses per unit volume. Theoretical studies of the dielectric parameters of onions presented their structure as a “capillary model”. The development of the design of a microwave installation for provides a complex effect of electrophysical factors when calibrating onions. The justification of the corona discharge intensity of electric-gas-discharge lamps is in UHFEMF. There is the study of the dynamics of onion-sowing heating, justification of effective treatment modes. The dynamics of onion heating shows that with the power of the microwave generators of 3.4 kW and Darsonval of 80 W, the drum drive power of 0.25 kW, it is possible to ensure the installation capacity of 150-200 kg/h at an energy cost of 0.025 kWh/kg.
