Effects of moisture content and salt content on heating rate in ohmic heating of rice paste were investigated. The rice paste was filled up in an insulated container. Electrical properties of the rice paste were examined for analyzing of heat generation.
Experimental results showed that the rice paste had an approximately uniform temperature, and the higher the temperature was, the faster it rose during ohmic heating. The maximum average heating rate was obtained in the moisture content range of 50 to 67%. The average heating rate varied linearly with the salt content. It was clarified that the rice paste could be considered as an equivalent circuit of a resistance, and the calculated temperatures agreed with the experimental data.
