Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0012] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example

[0013] See appendix Figure 1-2 As shown, a cooling device for lunch box production includes a support frame 1, on which a chain plate conveyor belt 3 is provided. A square silo equipment body 2 with inlet and outlet is provided around the chain plate conveyor belt 3. The square silo equipment body 2 is divided into a continuously arranged atomizing chamber 5, drying chamber 6, and cooling and disinfection chamber 7 by partitions 4. The chain plate 31 of the chain plate conveyor belt 3 is provided with micropores 32; The atomization chamber 5 is equipped with a water storage tank 52 fixed on the top surface of the main body 2 of the container equipment. The water storage tank 52 is connected to a set of ultra-micro atomizing nozzles 55 through a water distribution pipe 53. The bottom surface of the main body 2 of the container equipment corresponding to the ultra-micro atomizing nozzles 55 is equipped with a water collection trough 51 with an opening at the top. The bottom of the water collection trough 51 is equipped with a drain pipe 52. The drying chamber 6 includes a hot air generator 61 fixed on the upper and lower outer sides of the main body 2 of the square warehouse equipment. The hot air generator 61 is provided with an adjustable louvered air diffuser 62 extending into the interior of the main body 2 of the square warehouse equipment. The cooling and disinfection chamber 7 includes a set of germicidal lamps 71 and a normal temperature blower 72 installed on the top surface inside the main body 2 of the container equipment.

[0014] Preferably, the surface of the chain plate 31 is provided with a Teflon coating with a thickness of 0.5-0.8 mm.

[0015] Preferably, the inner side of the main body 2 of the container equipment is provided with a rock wool insulation layer with a thickness of 20-30mm.

[0016] Working Principle: The conveyor system utilizes a chain conveyor belt 3 with micro-perforations 32, effectively promoting airflow and collecting excess atomized water. This enhances conveying stability and improves internal ventilation. Inside the atomization chamber 5, rapid cooling via ultra-micro atomizing nozzles 55 prevents food container deformation caused by uneven heating from direct cold air. The food containers then pass through the drying chamber 6 and adjustable louvered diffusers 62 for rapid hot air convection, effectively evaporating residual water droplets. Finally, they pass through the cooling and disinfection chamber 7 for room temperature air drying and sterilization by the germicidal lamps 71. This simple assembly line operation achieves cooling, drying, disinfection, and uniform airflow for the food containers, effectively cooling them and preventing deformation due to uneven heating. This improves the stability and aesthetics of food container production and optimizes the production line structure.
