DETAILED DESCRIPTION

[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and apparently, the described embodiments only are a part of the embodiments of the utility model, not all the embodiments.

[0025] Embodiment 1:

[0026] Refer to Figures 1-5A double-layer sterilization device for a fruit juice beverage production line includes a base plate 1. A mounting frame 2 and a ladder frame 3 are fixed on the base plate 1. The mounting frame 2 primarily supports a first sterilization tank 4, which is fixedly mounted on the upper part of the mounting frame 2. A fruit juice inlet pipe 5 is installed on the upper part of the first sterilization tank 4. The fruit juice undergoes high-temperature sterilization in the first sterilization tank 4 through the fruit juice inlet pipe 5, equivalent to traditional heat sterilization. A second sterilization tank 6 is fixedly mounted between the mounting frame 2 and the base plate 1. Both the first and second sterilization tanks 4 and 6 are horizontally oriented. A fruit juice outlet pipe 7 is installed at the bottom of the second sterilization tank 6. A heater 8 is installed at the rear end of the base plate 1, and the heater 8 is connected to a heating pipe. 9 and the return pipe 10 are connected to the first sterilization tank 4. The heater 8 is mainly controlled by the controller 30. Different juice products require different heating temperatures, and the required temperature can be controlled in real time. It also achieves circulating heating. The first sterilization tank 4 is also connected to the second sterilization tank 6 through the liquid guide pipe 11. The second sterilization tank 6 is also connected to the compressor 12. The compressor 12 is installed on the base plate 1 and is located below the escalator frame 3. The compressor 12 is mainly connected to the ozone generator and then delivers ozone into the second sterilization tank 6. The controller 30 is also installed on the base plate 1 and is located below the escalator frame 3. The controller 30 is connected to the heater 8 by signal.

[0027] Both the juice inlet pipe 5 and the juice outlet pipe 7 are equipped with filter membranes 13. The filter membrane 13 in the juice inlet pipe 5 is equivalent to the first filtration, and the filter membrane 13 in the juice outlet pipe 7 is equivalent to the second filtration. This process further reduces impurities in the juice.

[0028] The first sterilization tank 4 is a double-layer tank, and a spiral heating coil 14 is installed between the double-layer tank. The two ends of the heating coil 14 are connected to the heating pipe 9 and the return pipe 10, respectively. A temperature sensor 15 is also provided on the first sterilization tank 4. The temperature sensor 15 is also connected to the controller 30. The heating coil 14 can transfer high temperature to the juice and can continuously circulate heating or cooling.

[0029] The first sterilization tank 4 is also equipped with a stirring shaft 16, which is connected to a stirring motor 17. The stirring motor 17 is installed on one side of the first sterilization tank 4, and a spiral blade 18 is provided on the stirring shaft 16. The stirring motor 17 is also connected to a controller 30. During the high-temperature sterilization process, the stirring motor is in the activated state, which ensures that the juice is dynamically heated, resulting in more thorough sterilization. Furthermore, the sterilization temperature and time can be controlled at any time during this process.

[0030] A filter 19 is also provided on the liquid guide pipe 11, and a pressure relief valve 20 is also installed on the upper part of the second sterilization tank 6. The pressure relief valve 20 is also connected to the controller 30. The filter 19 mainly prevents scale and other impurities from entering the second sterilization tank 6 during long-term use of the first sterilization tank 4.

[0031] The output end of the compressor 12 is connected to the high-pressure pipe 21, which is located above the second sterilization tank 6. The high-pressure pipe 21 is also connected to the second sterilization tank 6 through several vertical pipes 22. This process mainly involves using the ozone generated by the external ozone generator to sterilize the second sterilization tank 6 through the compressor 12.

[0032] The high-pressure pipe 21 is also symmetrically connected to the cross-shaped air inlet pipe 23. The output end of the cross-shaped air inlet pipe 23 is connected to the second sterilization tank 6. The cross-shaped air inlet pipe 23 is also equipped with a check valve 24. Ozone can be introduced into the tank from different parts of the second sterilization tank 6 through the cross-shaped air inlet pipe 23 and the vertical pipe 22. This allows the ozone to fully contact the juice, resulting in a larger contact area and indirectly a higher sterilization effect.

[0033] The second sterilization tank 6 is also equipped with a pressure sensor 25, which is also connected to the controller 30. During this process, the pressure sensor 25 can monitor the pressure changes inside the second sterilization tank 6 in real time to prevent the pressure from being too high.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
