The works on creation of technique of calculation of the electric corona ionization for storage of products with juicy plant products are summarized. The necessity to determine the effect of recombination of ions on the performance of these devices is proved. The dependence of the concentration of ions from the ionizer uptime, productivity and the recombination coefficient was obtained. It was determined that when calculating performance electric corona ionization for processing of plant products with succulent tissues outside the corona ions recombination can be ignored. Elucidation of the role of recombination in the processing of such products in the inter electrode space further research.
