Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-7This utility model provides a technical solution: It includes a frame 100, a control host 110 on one side of the frame 100, a sterilization tank 120 fixed to the inner wall of the frame 100 by bolts, a spiral guide plate 130 fixed to the inner wall of the sterilization tank 120, a feeding mechanism on the top of the frame 100, a sterilization mechanism inside the sterilization tank 120, the sterilization mechanism including a mounting sleeve 310 and a mounting bracket 320, multiple electrically heated quartz tubes 330 fixed to the outer side of the mounting bracket 320 by bolts, a waste heat recovery mechanism on the outer side of the sterilization tank 120, and a cooling system on the outer side of the frame 100. The machine employs a feeding mechanism to transport wheat flour and drive it to spiral flow within the sterilization tank 120. Multiple embedded electrically heated quartz tubes 330 perform high-temperature instantaneous sterilization of the wheat flour, facilitating rapid cooling and minimizing nutrient loss. The sterilization tank 120 and the spiral guide plate 130 form a spiral channel, forcing airflow into a vortex, extending the contact time between the wheat flour and the high-temperature airflow, and improving the efficiency of the sterilization operation. Furthermore, the centrifugal force generated during the spiral flow of the wheat flour evenly disperses the airflow into each vortex layer, preventing localized airflow overload that could lead to powder agglomeration, thus enhancing the practicality of the sterilization mixer.

[0028] Specifically, the feeding mechanism includes a mounting crossbar 210, which is fixed to the top of the frame 100 by bolts. A feeding hopper 220 is fixed to one side of the mounting crossbar 210, a feeding trough 230 is fixed to the bottom of the feeding hopper 220, a blower 240 is fixed to one side of the feeding trough 230, and a discharge trough 250 is fixed to the bottom of the sterilization tank 120. The wheat flour is fed through the feeding mechanism, and the processed wheat flour is discharged through the discharge trough 250.

[0029] Specifically, the waste heat recovery mechanism includes a fan mounting base 410, which is fixed to one side of the frame 100 by bolts. A suction fan 420 is fixed to one side of the fan mounting base 410, and a suction pipe 430 is fixed to one side of the suction fan 420. A filter cotton 431 is fixed to the inner wall of the suction pipe 430, and an air delivery pipe 440 is fixed to the side wall of the suction fan 420. By setting up the waste heat recovery mechanism, the suction pipe 430 is connected to the outer wall of the sterilization tank 120 at the end of the sterilization mechanism. During the sterilization operation, the suction fan 420 absorbs the waste heat inside the sterilization tank 120 through the suction pipe 430 and delivers this part of the waste heat to the wheat flour feeding part through the air delivery pipe 440, which can preheat the wheat flour and reduce the overall energy consumption of the machine.

[0030] Specifically, a fastening bracket 441 is fixed to the outside of the gas pipeline 440; by setting the fastening bracket 441 to fasten and support the gas pipeline 440, the stability of the gas pipeline 440 during waste heat recovery operation is ensured.

[0031] Specifically, the cooling mechanism includes a fan mounting plate 510, which is fixed to the outside of the frame 100 by bolts. A cold air fan 520 is fixed to one side of the fan mounting plate 510 by bolts. A connecting pipe 530 is fixed to the bottom of the cold air fan 520, and an air jet sleeve 540 is fixed to one end of the connecting pipe 530. The air jet sleeve 540 is fixedly connected to the sterilization tank 120. By setting up the cooling mechanism, after the sterilization operation of wheat flour is completed, the wheat flour enters the cooling zone of the lower half of the sterilization tank 120. The cold air fan 520 is started, and the cold air fan 520 delivers cold air to the air jet sleeve 540 through the connecting pipe 530. The air jet sleeve 540 releases cold air into the sterilization tank 120, which can quickly cool the wheat flour.

[0032] Working Principle: During operation, the sterilization mixer is controlled by the main control unit 110. Wheat flour is injected into the feeding trough 230 through the feeding hopper 220. Air is blown into the feeding trough 230 by the blower 240, propelling the wheat flour into the sterilization tank 120, thus feeding the wheat flour. Inside the sterilization tank 120, the wheat flour spirals down along the spiral guide plate 130. The sterilization tank 120 and the spiral guide plate 130 form a spiral sterilization channel, driving the wheat flour to flow spirally within the sterilization tank 120. Multiple embedded electrically heated quartz tubes 330 perform high-temperature instantaneous sterilization of the wheat flour, facilitating rapid cooling. The spiral channel formed by the sterilization tank 120 and the spiral guide plate 130 forces the airflow into a vortex, extending the contact time between the wheat flour and the high-temperature airflow. Secondly, the centrifugal force generated during the spiral flow of wheat flour can evenly disperse the airflow to each vortex layer, avoiding powder agglomeration caused by local airflow overload. The outer wall of the sterilization tank 120 at the end of the sterilization mechanism is connected to the suction pipe 430. During the sterilization operation, the suction fan 420 is started. The suction fan 420 adsorbs the waste heat inside the sterilization tank 120 through the suction pipe 430 and transports this waste heat to the wheat flour feeding part through the air delivery pipe 440, which can preheat the wheat flour. After the sterilization operation of the wheat flour is completed, the wheat flour enters the cooling zone of the lower half of the sterilization tank 120. The cold air fan 520 is started. The cold air fan 520 delivers cold air to the jet sleeve 540 through the connecting pipe 530. The jet sleeve 540 releases cold air into the sterilization tank 120, which can quickly cool the wheat flour.

Apart from that, the power supply module, circuit and electronic components and control module involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated.

Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and accompanying drawings.
