Abstract: The temperature and water content distribution in the microwave drying equipment of active rice was obtained by establishing the mass heat transfer model of continuous microwave drying active rice process, and the microwave intensity was 1 . 16, 2 . 75, 4 . Under the condition of 34 W / g, the experimental verification of the active rice temperature and moisture model was carried out to determine the correctness of the heat and mass transfer model.
The simulation and measured results show that: in the dry end of the continuous microwave dryer, when the temperature rises slowly, the microwave power is controlled accordingly, and the energy consumption of microwave drying is reduced. After the drying section, the temperature is reached, so that the temperature inside and outside the active rice material reaches Balance, the drying effect is more uniform, and the dry quality can be guaranteed. This study has guiding significance for the microwave heating process and control of reactive rice.
