Abstract:

In order to reveal the mechanism of combined convective and infrared radiation in rice drying process and analyze heat and mass transfer characteristics, a mathematical model of combined convective and infrared radiation was established. The heat and mass transfer process in rice drying was simulated. According to the drying conditions in numerical simulation, the test rig of combined convective and infrared radiation was built up to analyze the influence of the drying process under the different operating conditions. The results showed that there was high relativity between the numerical model curves and the experimental curves.
