[0002] Pasteurization, also known as low-temperature sterilization, is a widely used food processing technology. It uses a relatively low temperature (usually in the range of 60 to 85°C) to heat food for a certain period of time to kill microorganisms. Pasteurization is widely used in the processing of various foods, especially dairy products, juices, and beer. Through pasteurization, the shelf life of food can be effectively extended while maintaining its nutritional components and flavor.

[0003] The existing publicly available technology, application number CN201921021358.7, describes a stirring-type pasteurizer. This device has poor sterilization effect during use, cannot cool the pasteurized liquid, and may cause some damaged but not completely dead bacteria to revive and reproduce, resulting in changes in the flavor and texture of the food, thus affecting food safety. It is also inconvenient for subsequent continuous production and cannot clean the sterilization tank.

[0007] A pasteurization tank for concentrated fruit pulp includes a pasteurization tank and a cooling tank. A speed-regulating motor is located at the center of the top of the pasteurization tank. Two sets of booster water pumps are symmetrically arranged on either side of the speed-regulating motor. The booster water pumps penetrate the top of the pasteurization tank and are connected to high-pressure nozzles. A heater is located on the left side of the top of the pasteurization tank. A feed inlet is located on the right side of the top of the pasteurization tank. A top cover is located above the feed inlet, and a handle is connected to the top of the top cover. A filter box is located below the feed inlet, and a filter plate is connected to the bottom of the filter box. A sealing strip is located on the right side of the filter box. Symmetrical features are located below the filter box. There are two sets of pulleys. The output end of the speed-regulating motor is connected to a stirring rod.

[0016] Compared with the prior art, this utility model provides a concentrated fruit pulp pasteurization tank, which has the following beneficial effects:

[0017] (1) This utility model adopts a sterilization device consisting of a sterilization tank and a cooling tank. During the heating and sterilization of the fruit pulp, the cooling tank can be pre-cooled to prepare for the subsequent rapid cooling. After the sterilization process is completed, the fruit pulp is transferred from the sterilization tank to the cooling tank through the first solenoid valve to achieve efficient cooling. This effectively prevents damaged but not completely dead bacteria from reviving and multiplying again, thus ensuring the purity of the flavor and taste of the fruit pulp and avoiding the risk of quality decline. In addition, the separate design of the sterilization tank and the cooling tank not only optimizes the space layout but also improves the continuity and flexibility of production. The two operate independently in different spaces, which not only ensures the professionalism and efficiency of the sterilization and cooling process but also facilitates the continuity of the production line, bringing more reliable quality assurance and improved production efficiency to the processing of fruit pulp.

[0018] (2) This utility model employs two symmetrical booster water pumps mounted on the top of the sterilization tank. These pumps extend into the tank and are connected to two sets of high-pressure nozzles, allowing the cleaning mode to be activated when sterilization is stopped. During cleaning, the booster water pumps provide strong power, driving the high-pressure nozzles to spray high-pressure water, thoroughly and deeply rinsing the inner wall of the sterilization tank. Simultaneously, combined with the gentle heat generated by the heating block and the scraper connected to the edge of the first stirring paddle, a three-dimensional cleaning system is formed. The scraper adheres closely to the inner wall of the sterilization tank, effectively removing stubborn dirt and residue. The heating block, by moderately increasing the temperature inside the tank, accelerates the softening and decomposition of dirt, further enhancing the cleaning effect and greatly improving the cleanliness of the sterilization tank. This ensures the purity and quality of the subsequent fruit pulp products, laying a solid foundation for the smooth progress of the subsequent sterilization process. Attached Figure Description

[0037] Working principle:

[0038] In use, the fruit pulp is fed into the sterilization tank 1 through the feed inlet 8. This device consists of two parts: a sterilization tank 1 and a cooling tank 2. During the heating and sterilization process, the cooling tank 2 pre-cools the fruit pulp, preparing it for subsequent rapid cooling. After sterilization, the fruit pulp is transferred from the sterilization tank 1 to the cooling tank 2 via the first solenoid valve 21, achieving immediate and efficient cooling. This effectively prevents damaged but not completely dead bacteria from reviving and multiplying, ensuring the purity of the food's flavor and texture and avoiding the risk of quality degradation. Furthermore, the separate design of the sterilization tank 1 and the cooling tank 2 not only optimizes the space layout but also improves the continuity and flexibility of production. Operating independently in different spaces, this system ensures the professionalism and efficiency of the sterilization and cooling processes while facilitating the continuity of the production line. This provides more reliable quality assurance and improves production efficiency for fruit pulp processing. Two symmetrical booster water pumps 4 are installed on the top of the sterilization tank 1. The two booster water pumps 4 extend into the sterilization tank 1 and are connected to two sets of high-pressure nozzles 5, respectively. This allows the cleaning mode to be activated when the sterilization process is stopped. During the cleaning process, the booster water pumps 4 provide strong power to drive the high-pressure nozzles 5 to spray high-pressure water jets, thoroughly and deeply rinsing the inner wall of the sterilization tank 1. At the same time, combined with the heat generated by the heating block 7 and the scraper 18 connected to the edge of the first stirring paddle 16, a three-dimensional cleaning system is formed. The scraper 18 can adhere closely to the inner wall of the sterilization tank 1, effectively scraping away stubborn dirt and residues attached to it. The heating block 7, by moderately increasing the temperature inside the sterilization tank 1, accelerates the softening and decomposition of dirt, further improving the cleaning effect and greatly enhancing the cleanliness of the sterilization tank 1. This ensures the purity and quality of the subsequent production of fruit pulp products and lays a solid foundation for the smooth progress of the subsequent sterilization process.
