ABSTRACT: By establishing the mass and heat transfer model of the continuous microwave drying of activated rice, the temperature and moisture content distribution in the microwave drying equipment of activated rice were obtained. Under the conditions of microwave intensity of 1.16, 2.75 and 4.34 W/g, the temperature and moisture models of activated rice were validated experimentally to determine the correctness of the heat and mass transfer model.
The results of simulation and measurement show that the microwave power can be controlled when the temperature rises slowly at the end of the continuous microwave dryer, and the energy consumption of microwave drying can be reduced. After the drying stage, the temperature inside and outside of the active rice material can be balanced, the drying effect is more uniform and the drying quality can be guaranteed. The research has guiding significance for microwave heating technology and control of active rice.
