[0027] In the embodiment, when the dried fruits are put on the conveying belt 6 from the upper feeding layer 3, the dried fruits can enter the inside of the sterilization box 1 from the inlet 5 along the conveying belt 6 on the upper feeding layer 3, at this time, the sterilization box 1 sterilizes the upward side of the dried fruits by the microwave generated by the microwave generator 9, and as the conveying belt 6 continuously moves to the lower discharging layer 4, the dried fruits are guided onto the connecting plate 7, and as the connecting plate 7 is arranged at an inclined angle, the oval dried fruits are rolled from the connecting plate 7 to the lower discharging layer 4, so as to disturb the orientation of the dried fruits, thereby ensuring that the side or bottom of the dried fruits can also be directly irradiated by the microwave, and a more uniform sterilization effect is achieved, and on the lower discharging layer 4, the conveying belt 6 continues to convey the dried fruits forward until the dried fruits are discharged from the outlet 16, and the whole sterilization process is completed.
[0028] In the embodiment, in order to ensure that the dried fruits can be uniformly irradiated by the microwave, the sterilization box 1 is provided with microwave generators 9 corresponding to the upper feeding layer 3, the connecting plate 7 and the lower discharging layer 4, so that the dried fruits are irradiated by the microwave generated by the corresponding microwave generator 9 before, during and after rolling, thereby further improving the uniformity and efficiency of sterilization, and in addition, in order to further improve the sterilization effect, the conveying belt 6 is also improved in design;
[0029] Further, the inside of the sterilization box 1 is provided with a connecting column 8 for hoisting the microwave generator 9, wherein the two ends of the connecting column 8 are respectively connected with the microwave generator 9 and the inner wall of the sterilization box 1, and the side of the connecting column 8 facing the microwave generator 9 is provided with a mounting plate with screw holes, so that the connecting column 8 can be fixed with the microwave generator 9 by bolts, so that the microwave generator 9 can be hoisted above the corresponding upper feeding layer 3, connecting plate 7 and lower discharging layer 4;
