Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to a sterilization device for sealed containers. Background Technology

[0002] Autoclaving refers to the process of placing items in a sealed autoclave and using high-pressure saturated steam to denature the proteins and nucleic acids in microorganisms, thereby killing them. This method has a strong sterilization capacity and is the most effective and widely used sterilization method.

[0003] In particular, during the production of pickled radish, hot steam is usually used to heat the radish, which can not only effectively accelerate the dehydration of the radish and shorten its pickling time, but also make it easier for it to absorb salt and other seasonings during the pickling process, thus obtaining a unique flavor.

[0004] However, the existing sealed jars have a simple structure. When steam is injected into them, especially since the stirring structure and the steam structure are two separate parts, they cannot be effectively coordinated. At the same time, the dried radishes pile up at the bottom of the jar, and the steam is injected from the bottom, resulting in uneven heating of the dried radishes from top to bottom. Furthermore, because the steam injection point is too concentrated, simple stirring cannot make the dried radishes near the jar wall heat evenly, thus affecting the flavor of the pickled dried radishes. Utility Model Content

[0005] Based on the above description, this utility model provides a sealed container sterilization device to solve the problem that the stirring and heating structures of existing sealed containers operate independently and cannot be effectively coordinated, resulting in uneven heating of the dried radish and affecting the taste of the pickled radish.

[0006] This utility model is achieved through the following technical solution:

[0007] A sealed container sterilization device includes a sealed container, a stirring shaft rotatably mounted inside the sealed container, and a drive motor is also provided on the top of the sealed container. The output end of the drive motor is connected to the top end of the stirring shaft. Several stirring blades are also arranged obliquely on the outer side wall of the stirring shaft. A high-temperature sterilization component is also provided inside the stirring shaft. The air inlet and air outlet of the high-temperature sterilization component are respectively connected to a steam generator through high-pressure air pipes.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the top and bottom of the sealed tank are respectively provided with a feed inlet and a discharge outlet, and both the feed inlet and the discharge outlet are equipped with solenoid valves.

[0010] Furthermore, the high-temperature sterilization assembly also includes a gas supply pipe located at the bottom of the sealed container. The gas supply pipe is horizontally arranged and connected to a high-pressure gas pipe. The top surface of the gas supply pipe is also provided with three branch pipes. The stirring shaft is hollow inside, and the bottom end of the stirring shaft extends to the outside of the sealed container and has a through hole at the center of the bottom surface. A ball bearing is provided on the inner wall of the through hole. The top end of the branch pipe located at the center of the gas supply pipe is inserted into the center of the ball bearing with its tip facing upward. Both sides of the ball bearing are sealed by sealing rings.

[0011] Furthermore, the sealed container includes an inner shell and an outer shell, with a gap between the inner shell and the outer shell forming a heating chamber. The bottom of the heating chamber has an interface that communicates with two other branch pipes.

[0012] Furthermore, the interior of the stirring blade is also hollow and communicates with the stirring shaft, and the outer wall of the stirring blade is also provided with nozzles for injecting steam.

[0013] Furthermore, the top of the sealed tank is provided with an exhaust pipe, and the top of the heating chamber is provided with an air outlet pipe. Both the exhaust pipe and the air outlet pipe are connected to the inlet end of the steam generator through a high-pressure gas pipe and form a loop pipeline.

[0014] Furthermore, a booster pump is also provided at the output end of the steam generator.

[0015] Furthermore, a temperature sensor is also provided inside the sealed container, and a display is provided on the surface of the sealed container, which is electrically connected to the temperature sensor.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0017] This application improves upon the existing sealed container structure by combining the stirring and steam heating structures. This not only ensures that the piled-up dried radishes are heated evenly at all heights, but also allows for simultaneous heating using the internal heating chamber. This simultaneous internal and external heating avoids the temperature differences in different parts of the container caused by uneven heat transfer when relying solely on external heating. This ensures that all items inside the container are sterilized at the specified temperature, guaranteeing a consistent flavor in the pickled dried radishes. Attached Figure Description

[0023] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0025] Combination Figures 1-4 As shown, a sealed container sterilization device includes:

[0026] Sealed tank 1 is a metal tank with an inlet at the top and a outlet at the bottom.

[0027] The stirring shaft 2 is vertically installed inside the sealed tank 1 and is movably connected to the sealed tank 1 using a bearing structure. A drive motor 3 is also installed at the top of the sealed tube, with its output end extending downward and being connected to the top of the stirring shaft 2 for driving the stirring shaft 2 to stir the pickled radish inside the sealed tank 1.

[0028] The high-temperature sterilization component 4 is mounted on and connected to the stirring shaft 2 to heat the inside of the sealed tank 1, while the other end is connected to the steam generator 44 through the high-pressure gas pipe 43.

[0029] Specifically, in this embodiment, the side wall of the sealed container 1 is divided into an inner shell 12 and an outer shell 11, and a gap is left between the inner shell 12 and the outer shell 11 to form a heating chamber 13. Furthermore, an insulation layer is also covered on the outer side wall of the outer shell 11 to enhance the insulation function and prevent the heat from being consumed too quickly.

[0030] In addition, interfaces and air outlet pipes are provided at the top and bottom of the heating chamber 13, respectively, for circulating and transporting high-temperature steam.

[0031] The interiors of the stirring shaft 2 and the stirring blade 21 are both hollow and interconnected. Several spray holes are provided on the outer wall of the stirring blade 21 to spray steam onto the dried radish around the stirring blade 21, so as to improve the coverage of the steam. The bottom end of the stirring shaft 2 extends downward to the outside of the sealed tank 1, and a through hole is provided at the center of the bottom surface. The through hole is interconnected with the interior of the stirring shaft 2, and a ball bearing 22 is provided on the inner side wall.

[0032] The high-temperature sterilization component 4 includes a gas supply pipe 41 arranged horizontally at the bottom of the sealed tank 1, and the gas supply pipe 41 is connected to the steam generator 44 through a high-pressure gas pipe 43. Three branch pipes 42 are vertically arranged at the top of the gas supply pipe 41. The branch pipe 42 located in the middle position extends upward and is inserted into the center of the ball bearing 22. A sealing gasket is used at the connection to prevent steam from overflowing.

[0033] Based on the steam input structure described above, it is combined with the stirring structure so that the stirring blade 21 can simultaneously inject high-temperature steam into the dried radish at different heights during the rotation and stirring process, so that the dried radish at different heights can be at the same temperature.

[0034] Furthermore, two interfaces are provided at the bottom of the heating chamber 13, which are connected to the remaining two branch pipes 42 of the gas supply pipe 41. Therefore, the gas supply pipe 41 can simultaneously supply high-temperature steam to both the inside of the tank and the heating chamber 13. External heating can heat the entire sterilization tank, while internal heating can directly act on the items inside the tank. This simultaneous internal and external heating method avoids the temperature differences in different parts of the tank caused by uneven heat transfer when relying solely on external heating, ensuring that all items inside the tank can be sterilized at the specified temperature, thus improving the consistency of sterilization effect. Compared to external heating alone, simultaneous internal and external heating results in a more reasonable heat distribution within the tank, reducing heat loss from the tank walls and other parts, allowing energy to be more concentrated on the items being sterilized, improving energy utilization efficiency, and reducing energy consumption.

[0035] An exhaust pipe is also provided at the top of the tank. This exhaust pipe and the air outlet pipe at the top of the heating chamber 13 are connected to the inlet end of the steam generator 44 through the high-pressure air pipe 43 and form a loop pipeline so as to ensure that the high temperature state inside the tank is maintained stable by continuously supplying hot steam.

[0036] A booster pump 45 should also be installed at the output end of the steam generator 44 to control the steam delivery speed. At the same time, a temperature sensor is installed inside the tank, and a display is installed on the side wall of the tank to display the temperature changes inside the tank in real time, as well as the sterilization time, so that the staff can adjust and control it according to the needs.

[0037] Finally, it should be noted that 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this utility model.
