Description

Technical Field

[0001] This utility model relates to a bottle cap sealing vacuum sterilization structure, and more particularly to a bottle cap sealing vacuum sterilization structure applied after container filling. It can first use high-temperature steam to expel the cold air inside the container and perform instant sterilization before sealing the container, thereby improving the preservation and hygiene safety of the contents. Background Technology

[0002] Currently, canned foods, beverages, dairy products, and pickles commonly use glass bottles, metal cans, or plastic bottles as containers. During the production process, after filling, the contents must be sterilized and sealed immediately to prevent microbial contamination or oxidative spoilage. Existing canning and sealing technologies mostly involve placing the cap directly onto the container opening after filling and sealing it with a pressing or screw-on method, followed by high-temperature sterilization or pasteurization. However, this approach still has the following drawbacks:

[0003] Before sealing, cold air often remains inside the container. Even if high-temperature sterilization is carried out afterward, sterilization may still be incomplete, or negative pressure may be generated during the cooling process, causing the bottle cap to deform or leak. Moreover, existing technologies mostly perform high-temperature sterilization after sealing, so the heat energy cannot be applied to the inside of the container quickly and evenly. In particular, it is often difficult to completely remove bacteria or mold in the upper edge area of ​​the opening.

[0004] Traditional hot water or steam sterilization consumes a lot of energy and requires a long heating and cooling time, which is inefficient for large-scale production. Moreover, existing capping sterilization processes are mostly independent steps that require manual handling or additional equipment, making it difficult to integrate them closely with automated production lines.

[0005] In summary, the industry urgently needs a new bottle cap sealing and sterilization structure that can use high-temperature steam to be introduced into the upper edge space of the container opening before sealing, quickly expelling cold air and simultaneously performing instant sterilization; ensuring that a near-vacuum environment is formed inside the container to extend the shelf life of the contents; combining automated cap feeding, cap adjustment and sealing mechanisms to achieve continuous production; and reducing energy consumption through a circulating water and steam system to achieve the goals of environmental protection and high-efficiency production.

[0006] Therefore, the bottle cap sealing vacuum sterilization structure proposed in this utility model can effectively solve the shortcomings of the existing technology and greatly improve product quality and vacuum sterilization process efficiency. Utility Model Content

[0007] To achieve the above objectives, this utility model provides a bottle cap sealing vacuum sterilization structure, which includes a conveyor belt on the machine body for transporting containers, and a base at a corresponding position. The base has a container cap guiding unit, which allows the container cap to be temporarily placed at an angle on the side edge of the container opening without being fully sealed. A steam guiding seat is provided on the rear side of the base, forming a steam guiding groove. Steam is introduced through the high-temperature gas supply pipe of the vacuum sterilization unit and directly enters the space above the container opening to expel the internal cold air and perform sterilization. The vacuum sterilization unit of this utility model includes a compressed gas cylinder, gas valves, steam supply pipelines, and multiple sets of control components, and is equipped with a drain valve, a water outlet pipe, and a hot water circulation pipeline to realize the circulation of steam supply and condensate discharge; it is connected to a return water storage tank to ensure the continuous and stable operation of the steam system and reduce energy consumption. To achieve continuous automated production, this invention includes a container lid feeding cylinder and a container lid adjusting unit before the steam sterilization process. The container lids are arranged in an orderly manner using a vibration-assisted lid-sorting method and flipped so that the top surface faces upwards. The container lid guiding unit then positions the lids at the container opening. After steam sterilization, the container lids are sent to the pressing and sealing mechanism for sealing. The entire process is controlled by a control unit, minimizing manual intervention.

[0008] The beneficial effects of this invention are: it can effectively sterilize, and the steam is introduced into the container before sealing, which can directly kill bacteria on the upper edge of the container opening and the inner wall, avoiding the dead corner problem caused by sterilization after sealing; the space on the upper edge of the container opening can form a vacuum environment, mainly by rapidly replacing the cold air in the container with high-temperature steam, and forming a near-vacuum state after condensation, which improves the product shelf life and reduces the risk of oxidation; this invention adopts a steam and condensate circulation pipeline, supplemented by a return water storage tank, which can reduce energy waste and improve overall production efficiency; this invention automatically integrates cap supply, cap sorting, guiding, sterilization, sealing and control unit to form a continuous automated production process; this invention has a simplified structure and high reliability, and uses steam guide groove and positioning guide unit for precise alignment to ensure that steam can enter the container correctly, while taking into account structural stability and manufacturing convenience.
