[0023] The embodiment of the present utility model provides a microwave sterilization device for soft packaging of convenience foods, as Figures 1-4 shown, including a support seat 1; a first conveyor belt 2 and a second conveyor belt 3 provided on the support seat 1, with a height difference provided between the first conveyor belt 2 and the second conveyor belt 3; a material turning mechanism provided between the height differences; the material turning mechanism includes: a flipping shaft 4 rotatably disposed within the support seat 1; a servo motor 5 provided on the outer sidewall of the support seat 1, the output end of the servo motor 5 being key-fixedly connected to the end of the flipping shaft 4; a flipping plate 6 provided on the side of the flipping shaft 4 opposite to the first conveyor belt 2; a plurality of suction cups 7 provided on the flipping plate 6, and the plurality of suction cups 7 are arranged in an array.

[0024] It should be noted that since it is difficult for existing food soft packaging to be sterilized comprehensively, it is easy for bacteria to survive, which affects food safety. At the same time, the problem of inability to exhaust air in time may affect the sterilization effect and food quality. This solution significantly improves the sterilization effect and operation convenience. First, the cooperation of the turning plate 6 and the servo motor 5 ensures that the food soft packaging can be evenly turned during the sterilization process, so as to receive comprehensive microwave heating and sterilization treatment, effectively avoiding the problem of uneven sterilization, ensuring food safety and extending the shelf life. Second, the ingenious combination of the reserved opening on the outer wall of the sterilization box 8 with the sealing cover 16 and the transparent window 17 not only ensures the sealing of the sterilization box 8, prevents the entry of external pollutants, maintains a sterile environment, but also provides a clear observation path, enabling the staff to monitor the sterilization process in real time and ensuring the smooth progress of the sterilization operation. Finally, the design of the air outlet pipe 14 at the top of the sterilization box 8 not only discharges the dirty air and harmful gases in the box in time, keeps the air fresh and clean, but also ensures that the food soft packaging can quickly and evenly reach the set sterilization temperature.

[0025] Specifically, in this embodiment, this solution mainly includes a support base 1; first, the food soft packaging is conveyed into the sterilization box 8 through the first conveyor belt 2; inside the sterilization box 8, the microwave generator generates high-frequency electromagnetic waves, and these electromagnetic waves directly act on the food materials; the vibration and heating effects of the microwaves cause the molecules inside the food materials to move rapidly, thereby generating heat, achieving uniform and instantaneous heating and sterilization effects;

[0026] Subsequently, affected by the height difference between the first conveyor belt 2 and the second conveyor belt 3, the food soft packaging falls from the sterilization box 8 onto the turning plate 6; several suction cups 7 are installed on the turning plate 6, and these suction cups 7 are firmly adsorbed on the food soft packaging in an array distribution form, ensuring that it will not slip or move;

[0027] Then, the servo motor 5 starts to work, driving the turning shaft 4 to rotate; as the turning shaft 4 rotates, the turning plate 6 together with the food soft packaging adsorbed on it rotates, realizing the turning operation of the food soft packaging; finally, the turned food soft packaging falls onto the second conveyor belt 3 and continues the subsequent sterilization process; through such a turning operation, different positions of the food soft packaging can be sterilized, ensuring the comprehensiveness and uniformity of the sterilization effect; effectively improving the sterilization efficiency and food safety, and being applicable to the sterilization treatment of various food soft packaging.

[0028] In a further preferred embodiment of the present utility model, as Figures 1-3 shown, a sterilization box 8 is provided on the support base 1, a microwave generator (SG384) is provided inside the sterilization box 8, a feeding port 9 is opened at one end of the sterilization box 8, and a discharging port 10 is opened at the other end of the sterilization box 8.

[0029] In this embodiment, after the food soft packaging enters the sterilization chamber 8 from the feeding port 9, the material is uniformly heated to the set sterilization temperature after a period of microwave treatment in the sterilization chamber 8. Subsequently, the processed food soft packaging will flow out from the discharging port 10, completing the entire sterilization process.

[0030] In a further preferred embodiment of the present utility model, as Figures 1-3 shown, a guiding plate 11 is provided on one side of the supporting seat 1 adjacent to the discharging port 10, and a material guiding pipe 12 is communicated with one side of the supporting seat 1 adjacent to the guiding plate 11.

[0031] In this embodiment, when the food soft packaging is subjected to microwave sterilization treatment, they will flow out from the discharging port 10. Under the action of the guiding plate 11, these packages will slide or flow in a predetermined direction. Subsequently, they will enter the material guiding pipe 12 and be collected or transported therein. During the whole process, the guiding plate 11 and the material guiding pipe 12 cooperate together to ensure that the food soft packaging can leave the sterilization equipment smoothly and orderly.

[0032] In a further preferred embodiment of the present utility model, as Figure 3 shown, a plurality of air blowers 13 are communicated with the top of the sterilization chamber 8. One ends of the plurality of air blowers 13 are communicated with the sterilization chamber 8, and the other ends of the plurality of air blowers 13 are communicated with the same air outlet pipe 14.

[0033] In this embodiment, during the sterilization process, the air blowers 13 start to work, sucking the air in the sterilization chamber 8 and discharging it through the air outlet pipe 14. In this way, not only can the dirty air and harmful gases in the sterilization chamber 8 be discharged to keep the air in the sterilization chamber 8 fresh and clean, but also the heat generated by the microwave can be evenly distributed by circulating the air, improving the sterilization effect.

[0034] In a further preferred embodiment of the present utility model, as Figure 3 shown, microwave suppressors 15 are provided at the internal positions of the sterilization chamber 8 adjacent to the feeding port 9 and the discharging port 10.

[0035] In this embodiment, the application of the microwave suppressor 15 (NWE-Y01) in the sterilization chamber 8 is mainly to ensure the safety of the operators, prevent the leakage of microwave energy to the external environment, and at the same time ensure the uniform distribution of microwave energy in the sterilization chamber 8 to improve the sterilization effect.

[0036] In a further preferred embodiment of the present utility model, as Figures 1-2 shown, a plurality of reserved openings are provided on the outer side wall of the sterilization chamber 8, and sealing covers 16 are hinged and matched at the plurality of reserved openings. Transparent viewing windows 17 are provided on the plurality of sealing covers 16.

[0037] In this embodiment, a sealing cover 16 is hinged and fitted at each reserved opening. Its main function is to maintain the sealing property of the sterilization chamber 8. When the reserved opening does not need to be opened, the sealing cover 16 can be tightly closed on the reserved opening to prevent external air, dust or other pollutants from entering the interior of the sterilization chamber 8, thereby maintaining a sterile environment inside the sterilization chamber 8. To facilitate observing the situation inside the sterilization chamber 8, a transparent viewing window 17 is provided on the sealing cover 16. Through the transparent viewing window 17, the staff can directly see the material state, equipment operation condition, etc. inside the sterilization chamber 8 without opening the sealing cover 16. This not only facilitates the monitoring of the sterilization process but also ensures the sealing property of the sterilization chamber 8.

[0038] Working principle: First, the food soft packaging is conveyed to the feeding port 9 of the sterilization chamber 8 through the first conveyor belt 2 and then enters the sterilization chamber 8. Inside the sterilization chamber 8, the microwave generator generates high-frequency electromagnetic waves, and these electromagnetic waves directly act on the food material. The vibration and heating effects of the microwaves cause the molecules inside the food material to move rapidly, thereby generating heat and achieving uniform and instantaneous heating and sterilization effects.

[0039] After being subjected to microwave treatment in the sterilization chamber 8 for a period of time, the food soft packaging will be uniformly heated and reach the set sterilization temperature. Subsequently, affected by the height difference between the first conveyor belt 2 and the second conveyor belt 3, the food soft packaging falls from the sterilization chamber 8 onto the turning plate 6. Several suction cups 7 are installed on the turning plate 6, and these suction cups 7 firmly adsorb the food soft packaging in an array distribution form to ensure that it will not slip or move.

[0040] Then, the servo motor 5 starts to work, driving the turning shaft 4 to rotate. As the turning shaft 4 rotates, the turning plate 6 together with the food soft packaging adsorbed on it is turned over, realizing the turning operation of the food soft packaging. Such a turning operation can perform sterilization treatment on different positions of the food soft packaging to ensure the comprehensiveness and uniformity of the sterilization effect.

[0041] The turned-over food soft packaging falls onto the second conveyor belt 3 and continues the subsequent sterilization process. During the sterilization process, the fan 13 starts to work, sucking the air inside the sterilization chamber 8 and discharging it through the air outlet pipe 14. In this way, not only can the dirty air and harmful gases inside the sterilization chamber 8 be discharged to keep the air inside the sterilization chamber 8 fresh and clean, but also the circulated air can help evenly distribute the heat generated by the microwaves to improve the sterilization effect.

[0042] At the same time, the application of the microwave suppressor 15 near the feeding port 9 and the discharging port 10 in the sterilization chamber 8 is mainly to ensure the safety of the operators, prevent the leakage of microwave energy to the external environment, and at the same time ensure the uniform distribution of microwave energy inside the sterilization chamber 8 to improve the sterilization effect.

[0043] A number of reserved openings are provided on the outer wall of the sterilization chamber 8. A sealing cover 16 is hingedly fitted at each reserved opening, and its main function is to maintain the sealing performance of the sterilization chamber 8. When the reserved opening does not need to be opened, the sealing cover 16 can be tightly closed on the reserved opening to prevent external air, dust or other pollutants from entering the interior of the sterilization chamber 8, thereby maintaining a sterile environment inside the sterilization chamber 8. In order to facilitate observing the situation inside the sterilization chamber 8, a transparent viewing window 17 is provided on the sealing cover 16. Through the transparent viewing window 17, the staff can directly see the material state, equipment operation conditions, etc. inside the sterilization chamber 8 without opening the sealing cover 16.

[0044] After the entire sterilization process is completed, the processed food soft packages flow out from the discharge port 10 and slide or flow in a predetermined direction under the action of the guide plate 11, and then enter the guide pipe 12 for collection or transmission. The guide plate 11 and the guide pipe 12 cooperate together to ensure that the food soft packages can smoothly and orderly leave the sterilization equipment.
