Abstract: In order to improve the microwave energy utilization rate of the continuous microwave dryer and the drying quality of the germinated brown rice, the electromagnetic field simulation software HFSS is used to analyze the installation mode of the magnetron waveguide (horizontal, vertical, etc.) and the transition between the interior and the surface of the drying chamber ( The right angle and arc) affect the transmission and distribution of electromagnetic fields in the drying chamber, and optimize the installation position of the material conveyor belt in the drying room.
The results show that the installation mode of the magnetron waveguide of the continuous microwave dryer and the transition form between the six boundary surfaces in the drying chamber have significant influence on the uniformity and strength of the electric field distribution. The position and installation form of the output tube of the magnetron are germinated on the conveyor belt in the drying chamber. Brown rice has the most significant impact.
