The overall structure and working principle of multiple sources microwave combining with hot-air fluidized drying test device were described. The design of microwave drying chamber, the coupling transmission position of six magnetrons, and the vibrating fluidized device system were analyzed in detail, and their specific structure and main parameters were confirmed. The total mode number and quality factor of the microwave drying chamber were 106 and 1 398 respectively. The microwave field of six magnetrons single-side radiating microwave energy was more uniform, and the frequency of vibration motor could be adjusted to led materials uniform fluidized for different shapes and sizes of materials, so that the materials more uniformly absorbed the hot-air and microwave energy. The results of carrots performance experiment proved that the moisture contents difference of dried carrots was within 1.22%, and the dried product rate of maintaining carrot original color, smell and taste reached 88.63%.
