A sterilization and disinfection system comprises a clockwise driving motor, a counterclockwise driving motor, a high-temperature outer bin, a sterilizing inner chamber, a rotating main shaft, a sterilization frame and a temperature measurement sensor, wherein the sterilization frame is located inside the sterilizing inner chamber, the rotating main shaft penetrates through the middle of the sterilization frame, two driving ends of the rotating main shaft are connected with the output ends of the clockwise driving motor and the counterclockwise driving motor, and the high-temperature outer binsleeves the sterilizing inner chamber, a high-temperature air cavity is clamped between the high-temperature outer bin and the sterilizing inner chamber, the temperature measuring sensor in contact with the sterilizing inner chamber is arranged in the high-temperature air cavity, the temperature measurement sensor, a signal emitter and a power supply are located in the same circuit loop, and thetemperature measurement sensor comprises a metal shell, an input power line, an output power line, a spring and a wax block. By adopting the design, the sterilization and disinfection system not onlyhas good disinfection effect, but also has high disinfection efficiency.
