Description

Technical Field

[0001] This utility model relates to the field of food additive packaging sterilization technology, specifically to a food additive packaging sterilization device. Background Technology

[0002] Food additives must undergo rigorous sterilization before packaging to ensure their microbiological safety during transportation, storage, and sales. To prevent harmful microorganisms such as bacteria, mold, and viruses from being carried on the surface of packaging bags due to contact with the environment or human handling, specialized packaging bag sterilization equipment is usually installed on the production line. This equipment uses methods such as ultraviolet light, ozone, hydrogen peroxide gas, or hot air to perform non-contact sterilization on the packaging surface, thereby ensuring the hygiene and quality of the product.

[0003] As shown in the reference case "A Food Packaging Sterilization Device" (Announcement No. CN214550335U), the first chamber is filled with steam by a steam generator for sterilization, achieving the first sterilization. The combined use of the sterilization chamber, fan blades, and ultraviolet sterilization lamps performs secondary sterilization on the food packaging inside the second chamber. The airflow from the fan blades ensures comprehensive sterilization. The air outlet and filter screen filter and absorb the generated fumes, reducing air pollution. The rubber soft plate provides better sealing of the chamber, enhancing the sterilization effect and reducing food quality issues.

[0004] In practical applications, especially when using gaseous sterilizing media such as ozone to sterilize packaging surfaces, there are issues such as slow diffusion of the sterilizing media and uneven flow field coverage. As a result, when the packaging moves through the sterilization area, the contact time with the effective sterilizing gas is short and the contact area is limited, making it difficult to achieve sufficient sterilization and thus affecting the overall sterilization effect.

[0005] Based on this, the present invention designs a food additive packaging sterilization device to solve the above problems. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 A food additive packaging sterilization device includes a conveyor belt 1 and a sterilization chamber 2. The sterilization chamber 2 is fixedly installed on one side of the conveyor belt 1, and shielding curtains 21 are fixedly installed on both sides of the sterilization chamber 2. A packaging sterilization mechanism 3 is set inside the sterilization chamber 2 to adjust the sterilization effect according to the packaging size and improve the sterilization gas flow effect. The packaging sterilization mechanism 3 includes a distance detector 31 fixedly installed on one side of the sterilization chamber 2, a flow component 32 is set inside the sterilization chamber 2, and an adapter component 33 is also set inside the sterilization chamber 2.

[0028] In this embodiment of the utility model, the flow component 32 can guide and circulate the sterilization medium such as ozone or hydrogen peroxide gas filled inside the sterilization chamber 2 in a directional manner, avoiding the formation of dead corners or stagnant areas of sterilization gas inside the chamber, thereby increasing the effective contact time and contact area between the sterilization gas and the surface of the packaging bag, and improving the uniformity and efficiency of sterilization. The shielding curtain 21 is set at both ends of the inlet and outlet of the sterilization chamber 2, which can form a closed space during the packaging process, preventing the sterilization gas from leaking out and improving the sterilization concentration maintenance effect. The distance detector 31 is set at the entrance of the sterilization chamber 2, which can identify the height of the packaging bag about to enter the chamber in real time. The adapter component 33 adjusts the height of its internal sterilization device according to the detected height data.

[0029] It should be noted that existing food additive packaging sterilization devices typically include basic sterilization components such as a conveyor belt 1, a sterilization chamber 2, ultraviolet lamps 333, and ozone or hydrogen peroxide nozzles. The conveyor belt 1 continuously transports the packaging bags to be processed to the sterilization area. The sterilization chamber 2 forms a relatively sealed sterilization space to concentrate the sterilization medium and prevent leakage. It is usually equipped with ultraviolet lamps 333 for sterilization. A flow component 32 is located inside the sterilization chamber 2 to guide the flow of sterilizing gas, avoid dead zones, and improve sterilization uniformity. Its placement does not affect the packaging transport path. The adapter component 33 automatically adjusts based on the packaging height signal collected by the distance detector 31, allowing the sterilization device height to adapt to different packaging bags. A shielding curtain 21 is located at the inlet and outlet of the sterilization chamber 2 to prevent sterilizing gas leakage without affecting the original structure of the sterilization chamber 2 or the sterilization process, ensuring the normal operation of the device.

[0030] The shielding curtain 21 adopts a flexible rubber curtain or a self-resetting flip door structure, which can adapt to continuous packaging entry and exit and block the air exchange between the inside and outside of the sterilization chamber 2.

[0031] In some embodiments, such as Figure 2 and Figure 3As shown, in a preferred embodiment of the present invention, the flow component 32 includes a storage box 321 fixedly installed on the top of the sterilization chamber 2. A delivery pump 322 is fixedly installed on one side of the storage box 321. A delivery pipe 323 is fixedly installed at the output end of the delivery pump 322. The output end of the delivery pipe 323 extends into the interior of the sterilization chamber 2. A return pipe 326 is fixedly installed on the other side of the sterilization chamber 2. The other end of the return pipe 326 extends to the other side of the storage box 321, and the other end of the return pipe 326 is fixedly connected to the storage box 321.

[0032] In this embodiment of the invention, the flow component 32 uses a delivery pump 322 to transport the ozone or hydrogen peroxide and other sterilizing gases stored in the storage tank 321 to the interior of the sterilization chamber 2 via the delivery pipe 323, thereby achieving directional supply of sterilizing gases. After sterilization, the gas inside the sterilization chamber 2 flows back to the storage tank 321 through the return pipe 326 located on the other side, thereby achieving the recycling and closed-loop flow of the sterilizing medium and increasing the contact area and contact time between the packaging bag and the sterilizing medium.

[0033] A guide plate 324 is fixedly installed on one side of the sterilization chamber 2. Multiple nozzles 325 are fixedly installed on one side of the guide plate 324. The other side of the guide plate 324 is fixedly connected to the delivery pipe 323.

[0034] In this embodiment of the invention, multiple nozzles 325 are densely arranged according to the length of the guide plate 324 to expand the spray coverage area and improve the sterilization efficiency. The guide plate 324 limits the gas flow direction and guides it to be sprayed evenly into the sterilization chamber 2 along the multiple nozzles 325 to spray the packaging, thereby improving the stable contact between the sterilization gas and the packaging.

[0035] Multiple nozzles 325 are equidistantly distributed, and the nozzles 325 are located on one side of the conveyor belt 1.

[0036] In this embodiment of the invention, by arranging the nozzles 325 at equal intervals along the guide plate 324 and concentrating them on one side close to the conveyor belt 1, targeted gas spraying can be carried out on the surface of the packaging bag to further improve the sterilization efficiency.

[0037] A guide frame 327 is fixedly installed on the other side of the sterilization chamber 2, and one side of the guide frame 327 is fixedly connected to the return pipe 326.

[0038] In this embodiment of the invention, a guide frame 327 is provided on the other side of the sterilization chamber 2 and connected to the return pipe 326, so that the sterilization gas used inside the sterilization chamber 2 can be collected in a concentrated manner through the guide frame 327 and smoothly introduced into the return pipe 326, and finally returned to the storage box 321.

[0039] A guide groove 328 is provided on the other side of the guide frame 327. The guide groove 328 is connected to the inside of the sterilization chamber 2 and is set in the shape of a funnel.

[0040] In this embodiment of the utility model, by setting the guide groove 328 in the shape of a funnel and communicating with the inside of the sterilization chamber 2, the airflow can be effectively gathered after the sterilization gas is used and guided to flow into the return pipe 326 in a directional manner, thus forming a fluid centralized outlet structure.

[0041] In some embodiments, such as Figure 2 and Figure 4 As shown, in a preferred embodiment of the present invention, the adapter component 33 includes multiple electric push rods 331 fixedly installed on the top wall of the sterilization chamber 2. The output ends of the multiple electric push rods 331 are fixedly installed with the same movable frame 332, and multiple ultraviolet lamps 333 are provided at the bottom of the movable frame 332.

[0042] In this embodiment of the utility model, by setting an electric push rod 331, the ultraviolet lamp 333 can be automatically raised and lowered according to the size and height of different packaging bags, thereby achieving precise ultraviolet sterilization control, avoiding the problem of inconsistent sterilization distance caused by differences in packaging specifications, and improving the uniformity of sterilization and the effective utilization of ultraviolet intensity.

[0043] A reflector frame 335 is fixedly installed on the outside of the ultraviolet lamp 333, and a connecting plate 334 is fixedly installed on the top of the reflector frame 335. Multiple connecting plates 334 are fixedly connected to the bottom of the movable frame 332.

[0044] In this embodiment of the utility model, the reflector frame 335 can reflect and focus the ultraviolet light emitted by the ultraviolet lamp 333, thereby increasing the irradiation intensity of ultraviolet light in the vertical direction, enhancing the sterilization effect on the surface of the packaging bag, and reducing the scattering waste of ultraviolet light in space. The reflector frame 335 and the ultraviolet lamp 333 are integrated, without adding an extra interference structure inside the sterilization chamber 2, and will not affect the normal conveying of the packaging bag on the conveyor belt 1, ensuring the continuity and safety of the device operation.

[0045] It should be noted that when the ultraviolet lamp 333 exerts its sterilization effect, it usually relies on a certain intensity and irradiation time, such as 5 seconds or more, to destroy the DNA or RNA structure of microbial cells, thereby achieving the effect of killing bacteria, mold, viruses, etc. In this device, the distance between the ultraviolet lamp 333 and the packaging bag is controlled by the electric push rod 331, so that the ultraviolet irradiation surface can be as close as possible to the surface of the packaging bag, thereby achieving a higher sterilization intensity within a limited irradiation time. In addition, combined with the focusing and reflection effect of the reflector frame 335 on ultraviolet light, the light intensity and range of action can be further enhanced, effectively improving the sterilization efficiency per unit time. Moreover, the running speed of the conveyor belt 1 can also be set according to the sterilization requirements, so that the packaging bag has sufficient residence time under the ultraviolet lamp 333, thereby ensuring that the ultraviolet sterilization achieves the expected effect. Therefore, in terms of structural fit and usage process, this device has the complete conditions to achieve effective ultraviolet sterilization.

[0046] In this embodiment of the invention, the packaging bag is continuously fed into the sterilization chamber 2 via the conveyor belt 1, and the shielding curtain 21 forms a relatively sealed sterilization space at the inlet and outlet. During the sterilization process, the flow component 32 is first driven by the delivery pump 322 to deliver the sterilization gas, such as ozone or hydrogen peroxide, from the storage box 321 to the sterilization chamber 2 through the delivery pipe 323. After the gas enters, its flow direction is limited by the guide plate 324, and it is directionally sprayed onto the side near the conveyor belt 1 through multiple equally spaced nozzles 325, achieving a comprehensive sterilization treatment of the packaging bag surface. At the same time, the guide frame 327 and funnel-shaped guide groove 328 at the tail of the sterilization chamber 2 are used to collect the used gas and guide it into the return pipe 326, realizing the continuous utilization of the sterilization gas. The distance detector 31 detects the height information of the packaging bag in real time, which can drive the electric push rod 331 to synchronously adjust the position of the moving frame 332, thereby changing the working height of the ultraviolet lamp 333, realizing close-range ultraviolet sterilization of packaging bags of different sizes. The reflector frame 335 works with the ultraviolet lamp 333 to directionally irradiate, enhance the concentration of effective ultraviolet energy, and improve sterilization efficiency.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
