Description

Technical Field

[0001] This utility model relates to the technical field of liquid dairy product production equipment, and in particular to an immersion sterilization system. Background Technology

[0002] In the food processing industry, especially in the production of aseptically packaged UHT (ultra-high temperature sterilization) liquid dairy products containing flavorings and high protein content, sterilization processes have a crucial impact on product quality. Due to the high protein content of these products, conventional sterilization methods are insufficient to meet the dual requirements of efficient sterilization and component preservation. Therefore, immersion sterilization machines are typically used to heat-treat the materials to achieve thorough microbial elimination and ensure food safety. However, existing immersion sterilization systems include a flash evaporation dehydration step, which aims to improve sterilization efficiency by rapidly evaporating some moisture under reduced pressure. However, during flash evaporation, moisture and flavorings are simultaneously extracted from the material, resulting in a significant loss of aroma components in the final product, thus diluting the flavor and affecting quality and market competitiveness. This problem has not yet been effectively solved in current technology, limiting the diversified development and high-quality production of flavored liquid dairy products. Therefore, how to effectively retain flavoring components during sterilization has become an urgent technical problem to be solved. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide an immersion sterilization system for effectively retaining the fragrance components in the product during the sterilization process.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please refer to the following: Figure 1 As shown, an embodiment of this utility model provides an immersion sterilization system, which includes an aseptic liquid pipeline 100, a base material sterilization pipeline 200, and a fragrance sterilization pipeline 300. The aseptic liquid pipeline 100 is used to connect to a filling device. The base material sterilization pipeline 200 includes a liquid sterilization pipeline 210 connected to the aseptic liquid pipeline 100, and a sterilization tank 220, a degassing tank 230, and an aseptic tank 240 disposed on the liquid sterilization pipeline 210. The fragrance sterilization pipeline 300 includes a fragrance sterilization pipeline 310 and a fragrance sterilization section 320 disposed on the fragrance sterilization pipeline 310. The fragrance sterilization pipeline 310 connects to the base material sterilization pipeline 200 located between the degassing tank 230 and the aseptic tank 240. The fragrance sterilization section 320 is used to heat the fragrance to the sterilization temperature.

[0029] Overall, this immersion sterilization system is suitable for processing liquid foods in a continuous flow state using heat treatment methods. By independently setting the spice sterilization section 320, the spices can be sterilized without undergoing a flash evaporation dehydration step, thereby effectively avoiding the problem of flavor components being extracted during the dehydration process and significantly improving the flavor stability and quality of the final product.

[0030] Specifically, this invention addresses the shortcomings of existing immersion sterilization systems, which suffer from severe aroma loss when processing high-protein liquid dairy products containing flavorings. By treating the flavorings and main ingredients separately, precisely controlling the temperature for sterilization, and mixing them at appropriate process points, not only is the loss of flavorings avoided, but the risk of heat-sensitive components decomposing or deteriorating due to prolonged heating is also reduced.

[0031] In addition, the immersion sterilization system has a reasonable structural design, strong process compatibility, and is easy to modify and apply on the basis of existing production lines. It has good prospects for industrialization and promotion, and is particularly suitable for the continuous production needs of high-quality, high-value-added liquid dairy products.

[0032] In an embodiment of this utility model, an interface structure is provided on the liquid sterilization pipeline 210, and the fragrance sterilization pipeline 310 is connected to the liquid sterilization pipeline 210 through the interface structure.

[0033] In the embodiments of this utility model, the designer can adjust the heating method of the fragrance sterilization section 320 according to the needs of use, and no specific limitations are made here. For example, the fragrance sterilization section 320 can be preheated by an external heating device.

[0034] In an embodiment of this utility model, the fragrance sterilization pipeline 300 further includes a fragrance preheating section 330 disposed on the fragrance sterilization pipeline 310 and located upstream of the fragrance sterilization section 320, and a fragrance cooling section 340 disposed on the fragrance sterilization pipeline 310 and located downstream of the fragrance sterilization section 320. The fragrance preheating section 330 is used to preheat the fragrance, and the fragrance cooling section 340 is used to cool the fragrance.

[0035] Specifically, the fragrance preheating section 330 is used to preheat the fragrance before sterilization, allowing it to quickly reach the target sterilization temperature, thereby reducing the adverse effects of heat shock on the fragrance components. The fragrance cooling section 340 is used to quickly cool the fragrance to the filling temperature after sterilization, effectively preventing the fragrance from decomposing or deteriorating due to prolonged heating.

[0036] By combining spice preheating, precise sterilization, and rapid cooling, not only is sterilization efficiency and safety improved, but the original flavor and stability of the spices are also preserved to the greatest extent, thereby significantly improving the quality and consistency of the final product.

[0037] In an embodiment of this utility model, the fragrance sterilization pipeline 300 further includes a fragrance material pump 350 disposed on the fragrance sterilization pipeline 310 and located upstream of the fragrance preheating section 330.

[0038] Specifically, the spice material pump 350 is used to stably and continuously transport the spice from the spice tank 370 to the spice preheating section 330, ensuring that the spice can be uniformly heated and reach a suitable sterilization temperature before entering the spice sterilization section 320.

[0039] By controlling the flow rate and pressure of fragrances with an independent fragrance material pump 350, not only is the controllability of the fragrance sterilization process improved, but the problem of uneven sterilization or loss of aroma components caused by flow fluctuations is also avoided.

[0040] Designers can adjust the heating method of the fragrance preheating section 330 according to usage needs, and no specific restrictions are imposed here. For example, the fragrance preheating section 330 can be preheated by an external heating device.

[0041] In an embodiment of this utility model, the fragrance sterilization pipeline 300 further includes a one-way valve 360 ​​disposed on the fragrance sterilization pipeline 310 and located downstream of the fragrance cooling section 340.

[0042] Specifically, the one-way valve 360 ​​is used to prevent liquid materials from flowing back into the fragrance pipeline during the mixing process of fragrance and liquid base material, thereby avoiding contamination or blockage of the fragrance pipeline. At the same time, it ensures that the fragrance flows into the base material sterilization pipeline 200 only in one direction under the set process conditions. This not only improves the hygiene safety and operational stability of the system, but also effectively ensures the accuracy of fragrance addition and the consistency of product flavor, further enhancing the reliability and applicability of the entire immersion sterilization system.

[0043] In an embodiment of this utility model, the immersion sterilization system further includes a fragrance tank 370, which is connected to a fragrance sterilization pipeline 310.

[0044] Specifically, the fragrance tank 370 is used to store fragrances or flavorings and ensures a stable supply of flavorings by connecting to the fragrance sterilization pipeline 310. By directly connecting the fragrance tank 370 to the fragrance sterilization pipeline 300, it is ensured that the flavorings continuously and uniformly enter the subsequent preheating, sterilization and cooling stages according to process requirements, avoiding volatilization or contamination of flavorings during transportation, and improving product quality and production efficiency.

[0045] In this embodiment of the invention, the aseptic tank 240 is provided with a stirring mechanism 241. Specifically, the stirring mechanism 241 is used to continuously or intermittently stir the material in the tank during storage to maintain the uniformity and stability of the material composition and prevent product quality fluctuations caused by material sedimentation or stratification.

[0046] In an embodiment of this utility model, the base material sterilization pipeline 200 further includes a liquid preheating section 250 disposed on the liquid sterilization pipeline 210 and located upstream of the sterilization tank 220, and a liquid cooling section 260 disposed on the liquid sterilization pipeline 210 and located between the degassing tank 230 and the sterile tank 240. The liquid preheating section 250 is used to preheat the liquid, and the liquid cooling section 260 is used to cool the liquid.

[0047] Specifically, the liquid preheating section 250 is used to preheat the liquid so that it gradually reaches the appropriate sterilization temperature, thereby improving sterilization efficiency and reducing the heat load in the sterilization tank 220; the liquid cooling section 260 is used to quickly cool the sterilized liquid to the appropriate storage or filling temperature to prevent component deterioration or flavor loss caused by prolonged high temperature.

[0048] The liquid preheating section 250 and the liquid cooling section 260 can work together to control the temperature change curve of the liquid material, which not only optimizes the temperature control in the liquid sterilization process, but also effectively improves product quality and energy efficiency, and further enhances the stability and applicability of the entire sterilization system.

[0049] Designers can adjust the heating method of the liquid preheating section 250 according to usage requirements, and no specific restrictions are imposed here. For example, the liquid preheating section 250 can be preheated by an external heating device.

[0050] In an embodiment of this utility model, the base material sterilization pipeline 200 further includes a homogenizer 270 disposed on the liquid sterilization pipeline 210 and placed between the degassing tank 230 and the liquid cooling section 260.

[0051] Specifically, the homogenizer 270 is used to homogenize degassed liquid materials, making the texture of the liquid materials more uniform, effectively improving the taste and quality of liquid products, enhancing their physical stability, and preventing quality problems caused by particle settling or fat floating during storage.

[0052] In an embodiment of this utility model, the base material sterilization pipeline 200 further includes a liquid material pump 280 disposed on the liquid sterilization pipeline 210 and located upstream of the sterilization tank 220.

[0053] Specifically, the liquid material pump 280 is used to stably and continuously transport liquid materials from the upstream section to the sterilization tank 220, ensuring the smoothness of the entire sterilization process and the stability of the system pressure.

[0054] By setting up a liquid material pump 280, not only is the accuracy and controllability of liquid delivery improved, but the problem of uneven sterilization or process failure caused by flow fluctuations or unstable pressure is also effectively avoided.

[0055] In an embodiment of this utility model, the immersion sterilization system further includes a liquid feed cylinder 290, which is connected to a liquid sterilization pipeline 210.

[0056] Specifically, the liquid feed cylinder 290 is connected to the liquid sterilization pipeline 210. The liquid feed cylinder 290 is used to receive and temporarily store the liquid material to be sterilized, providing a stable supply for the subsequent sterilization process.

[0057] By setting up the liquid feed cylinder 290, the liquid material can be initially buffered and evenly conveyed, effectively reducing the impact of feed fluctuations on the stability of the sterilization system. At the same time, it is convenient to centrally control and monitor the feeding process, thereby improving the continuity and automation of the sterilization system and ensuring the stability of product quality and production efficiency.
