[0022] The present invention will be further described below with reference to the accompanying drawings: Example

[0023] Reference Figure 1-5 A clog-resistant high-temperature sterilization system for kelp juice includes a high-temperature sterilization tank 1, wherein: an electric discharge valve 2 is fixedly installed at the bottom outlet of the high-temperature sterilization tank 1, a stirring mechanism is installed in the high-temperature sterilization tank 1, and a filter is fixedly installed on one side of the high-temperature sterilization tank 1; Specifically, the high-temperature sterilization tank 1 is used for high-temperature sterilization of kelp juice. Its operating temperature range is 120°C to 135°C, and the sterilization time is adjustable (e.g., 5 minutes to 30 minutes) to kill microorganisms in the material while preserving nutrients. The sterilization tank 1 can employ a known electrically heated sterilization tank structure, for example, by heating the inside of the tank with a resistance wire, and is equipped with a temperature sensor (e.g., a PT100 platinum resistance temperature sensor) and a controller (e.g., a PID controller) to maintain a stable sterilization temperature. Specifically, refer to a sterilization device disclosed in the publicly available document CN 219558161 U.

[0024] In this invention, the specific model of the high-temperature sterilization tank 1 is not limited. Its core function is to achieve sterilization through high temperature, and the sterilization parameters (temperature and time) can be adjusted according to the characteristics of the material (such as the initial total bacterial count and viscosity of kelp juice). The electric heating sterilization tank is chosen as the implementation method because of its high heating efficiency (thermal response time ≤ 2 minutes) and precise temperature control (temperature fluctuation range ± 1℃). Furthermore, those skilled in the art can select existing products that comply with standards such as GB 4806.9-2016 "National Food Safety Standard for Metal Materials and Products in Contact with Food" according to actual needs. Specifically, the filter includes a conical filter tank 6, an inlet pipe 7, a filter screen 11, a sealing cover 15, and an inlet pipe 16. The bottom of the conical filter tank 6 is fixedly connected to the upper interior of the high-temperature sterilization tank 1 through the inlet pipe 7. The filter screen 11 (with a filter mesh size of 0.5-2mm and made of 304 stainless steel) is rotatably installed inside the conical filter tank 6. A scraper assembly is detachably installed inside the conical filter tank 6, positioned above the filter screen 11, and there is rotatable contact between the filter screen 11 and the scraper assembly. This allows the scraper assembly to automatically scrape away impurities (such as kelp fragments and sand) intercepted on the filter screen 11 as the filter screen 11 rotates, causing the impurities to move along the scraper assembly into the slag discharge port 9. The top of the conical filter tank 6 is detachably equipped with a sealing cover 15 (fixed by quick-release bolts) for later replacement of the filter screen 11. A drive mechanism is fixedly installed on the sealing cover 15, and the drive mechanism is inserted into the filter screen 11 so that the filter screen 11 can be driven to rotate. Specifically, the sealing cap 15 is equipped with a feed pipe 16, which communicates with the inside of the conical filter tank 6. This allows the seaweed juice to be sterilized to be transported into the conical filter tank 6 via the feed pipe 16, and impurities in the seaweed juice to be filtered through the filter screen 11. Furthermore, the flow rate of the feed pipe 16 can be controlled by a flow meter (such as an electromagnetic flow meter), with a flow rate range of 50-200 L / min, to match the processing capacity of the subsequent sterilization tank.

[0025] Specifically, the stirring mechanism includes a shaft seat 3, a motor 4, and a stirring shaft 5. The motor 4 is fixedly mounted on the top of the exterior of the high-temperature sterilization tank 1 via the shaft seat 3. The stirring shaft 5 is rotatably mounted inside the high-temperature sterilization tank 1. The output end of the motor 4 extends into the high-temperature sterilization tank 1 via the shaft seat 3 and is fixedly connected to the top of the stirring shaft 5, so that the motor 4 drives the stirring shaft 5 to rotate inside the high-temperature sterilization tank 1 (speed range of 30-100 rpm), thereby ensuring that the kelp juice inside the high-temperature sterilization tank 1 is thoroughly and evenly sterilized. Furthermore, a spiral stirring blade is welded onto the stirring shaft 5, with a blade diameter of 0.6-0.8 times the inner diameter of the high-temperature sterilization tank 1, to enhance the stirring effect.

[0026] Specifically, the conical filter tank 6 has an integrated annular support edge 8 (made of polytetrafluoroethylene, which has better corrosion resistance than metal) coaxially arranged inside. The filter screen 11 is rotatably mounted above the annular support edge 8. The inner diameter of the annular support edge 8 is smaller than the diameter of the filter screen 11 (the difference ranges from 2 to 5 mm) so that the filter screen 11 can be supported by the annular support edge 8 and leakage can be reduced.

[0027] Specifically, a slag discharge port 9 is provided on one side of the upper part of the conical filter tank 6. The lowest point of the slag discharge port 9 is flush with the upper surface of the filter screen 11, so that impurities intercepted by the filter screen 11 can be automatically discharged through the slag discharge port 9. Furthermore, an impurity collection container (such as a plastic bucket) with a volume of 5-10L can be connected below the slag discharge port 9 to meet the needs of continuous production.

[0028] Specifically, a positioning notch 10 is provided on the side of the conical filter tank 6 near the slag discharge port 9. One end of the scraper assembly is detachably and fixedly installed in the positioning notch 10 (by bolts) to ensure the stability of the scraper assembly. Furthermore, the depth of the positioning notch 10 is 1.2-1.5 times the thickness of the scraper assembly to prevent loosening during operation. Specifically, a square shaft 14 (made of 45# steel, with chrome plating for rust prevention) is coaxially fixed on the upper surface of the filter screen 11, and the filter screen 11 is connected to the drive mechanism through the square shaft 14.

[0029] Specifically, the drive mechanism includes a bearing seat 17, a motor 18, and a square shaft 19. The motor 18 is fixedly mounted on the outside of the sealing cover 15 via the bearing seat 17. The output end of the motor 18 is equipped with an integrated square shaft 19 (the side length of the square shaft section is 10-15mm). The square shaft 19 rotates and extends into the conical filter tank 6 and is inserted into the square shaft 14. The arrangement of the square shaft 14 and the square shaft 19 facilitates the disassembly and assembly of the filter screen 11 and the drive mechanism (disassembly and assembly time ≤ 5 minutes). At the same time, it does not affect the motor 18 driving the filter screen 11 to rotate (the rotation direction is clockwise, and the speed range is 10-30rpm).

[0030] Specifically, the scraper assembly includes a scraper 12 and a semi-circular ring 13. One end of the scraper 12 is bolted into the positioning notch 10 for easy disassembly and replacement (replacement interval recommended every 3-6 months). The other end of the scraper 12 is fixedly connected to one end of the semi-circular ring 13. Both the scraper 12 and the semi-circular ring 13 are positioned above the filter disc 11, and the square shaft 14 rotates coaxially within the semi-circular ring 13 (gap range 0.5-1mm). Furthermore, the scraper 12 is made of polyoxymethylene (POM) with a hardness of HRC80-85, exhibiting superior wear resistance compared to ordinary plastics.

[0031] It should be noted that the electrical equipment involved in this case (such as motor 14, motor 218, and temperature sensor) are all controlled by external controllers, such as PLC controllers (the model can be Siemens S7-200 series), so they will not be described in detail here.

[0032] In this embodiment, during use, the kelp juice to be sterilized is conveyed to the conical filter tank 6 through the feed pipe 16 (the conveying pressure is 0.1-0.3MPa), and the impurities in the kelp juice are filtered through the filter screen 11. During the filtration process, the filter screen 11 is driven to rotate by the motor 18 (the rotation direction is opposite to the relative movement direction of the scraper assembly). In this way, under the action of the scraper assembly, the impurities retained on the filter screen 11 are automatically moved along the scraper assembly into the slag discharge port 9 and automatically discharged through the slag discharge port 9. The filtered kelp juice will enter the high-temperature sterilization tank 1 through the feed pipe 7 for sterilization (the inner diameter of the feed pipe 7 is 50-80mm to reduce flow resistance).

[0033] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
