FEM Analysis and Validation of Ohmic Heating Process of Soymilk
摘要
Abstract
In tofu making by ohmic heating, the textural uniformity of tofu is greatly influenced by the temperature distribution in soymilk. A 2-D static model was developed to visualize the change of temperature distribution in soymilk during ohmic heating process. Experimental validation of the temperature distribution obtained by mathematical modeling was performed by temperature measurement. Electrical conductivity of soymilk was correlated with temperature, uniform distribution of temperature can be obtained and heating rate is increased with the temperature. During ohmic heating process from 50 s to 300 s, the maximum temperature difference in soymilk greatly increased from 3℃ to 20. 2℃. Root mean square error between experimental and simulated data was 1. 86% , which indicated that numerical simulation was effective in predicting temperature distribution during ohmic heating process.关键词
