In this research, the effective parameters on Ohmic heating in aseptic and heating applications were studied. For this purpose, two- and three-dimensional Ohmic heating models in a two phase bio-solid-liquid system were developed. In these models, effects of particles distribution, particles size, effect of electrical conductivity on heating, overall heating of mixture and effect of salt concentration on heating rate were investigated. Temperature distribution profile, effects of intensity and distribution of electrical field on total temperature, and type of salt on phase electrical conductivity was also investigated. The modeling equation was solved with Finite Elements Method. The results showed that in Ohmic heating, heat diffusion in entire products was faster than the conventional methods, and it was accomplished with almost an equal rate in both phases.

Keywords: Ohmic heating; finite element method; effective parameter; bio-solid-liquid; static
