Description

Technical Field

[0001] This utility model relates to the field of heat energy exchange technology, and in particular to a heat energy exchange system for sterilizing dairy products. Background Technology

[0002] Dairy products may contain various harmful microorganisms, including bacteria, molds, and yeasts. Raw milk may contain pathogens such as Escherichia coli, Staphylococcus aureus, and Salmonella. The presence of these microorganisms can lead to food poisoning in consumers, causing symptoms such as vomiting, diarrhea, and fever. Sterilization can effectively kill or reduce the number of these harmful microorganisms, thereby protecting consumers' health. The growth and reproduction of microorganisms is one of the main causes of dairy product spoilage. Sterilization can inhibit the activity of microorganisms and slow down the rate of product spoilage. For example, pasteurized milk can have a shelf life of several days to more than ten days under suitable storage conditions. Sterilized dairy products can have a shelf life of up to several months if unopened. Appropriate sterilization processes help maintain the nutritional components and sensory quality of dairy products. Excessive sterilization may lead to protein denaturation and vitamin loss in milk, while precise sterilization can kill harmful microorganisms while preserving the nutritional value and flavor of dairy products to the greatest extent.

[0003] A search revealed Chinese Patent Publication No. CN209788352U, which discloses a dairy product sterilization device, comprising a tank body. Inside the tank body is a spiral-shaped material pipe. The inlet end of the material pipe is connected to a feeding pipe and a cleaning agent supply pipe via a first three-way connector. The feeding pipe is equipped with a first shut-off valve and a filter. The cleaning agent supply pipe is equipped with a self-priming pump and a second shut-off valve connected to a cleaning agent supply tank. The outlet end of the tank body is connected to a discharge pipe and a cleaning agent discharge pipe via a second three-way connector. The discharge pipe is equipped with a third shut-off valve, and the cleaning agent discharge pipe is equipped with a fourth shut-off valve. A heater is installed at the bottom of the tank body, and multiple ultraviolet disinfection lamps are evenly spaced along the inner circumferential wall of the tank body. This invention combines sterilization with ultraviolet sterilization, resulting in better sterilization effect and helping to maintain smooth material flow in the pipes for a long time, reducing equipment failure. However, the above structure does not take into account timely cooling of dairy products after sterilization, which may lead to excessive protein denaturation, affecting the original flavor of dairy products and hindering the improvement of product quality.

The lower inner side of the water tank 9 is connected to the heater 10 via a fixing device. The upper right side of the water tank 9 is connected to the conveying pipe 3 11 via a connecting device. The right end of the conveying pipe 3 11 is connected to the cooling hub box 12. A circulation mechanism 2 is provided on the right side of the raw material cylinder 1. This circulation mechanism 2 is specifically used to effectively exchange heat with dairy products to ensure temperature control of dairy products during processing. During the heating stage, the heating element in the preheating tank 8 heats the milk in the preheating tank 8. The water in the tank is heated by the heater 10 and then transfers the heat to the milk in the tank to reach the sterilization temperature.

[0041] Please see the appendix Figure 4 - Appendix Figure 5The circulation mechanism 2 includes a cooling tank 201. The left side of the cooling tank 201 is fixedly connected to the outer wall of the conveying pipe 11, ensuring that the cooling tank 201 can receive fluid from the conveying pipe. A cold liquid pipe 202 is connected to the front side of the cooling tank 201, and the front end of the cold liquid pipe 202 is connected to a cooling device 203. This ensures that the cooling medium can be quickly and effectively transferred to the cooling device 203, thereby improving the cooling efficiency.

A fixing lever 207 is fixedly connected to the right side of the fixing plate 206. The front right end of the heat exchange tank 205 is connected to the liquid outlet pipe 208. In this way, the cooled fluid can be smoothly discharged from the device to complete the entire cooling cycle. The valves and control components in the pipeline can accurately control the flow rate and temperature of the medium. By adjusting the flow rate of the hot medium and the cold medium through the regulating valve, the rate of heat exchange and the temperature of the final product can be controlled.

[0042] Specifically, the circulation mechanism 2 includes a cooling tank 201. The left side of the cooling tank 201 is firmly fixedly connected to the outer wall of the conveying pipe 11. This type of pipe can be made of stainless steel or plastic. Stainless steel pipe has good corrosion resistance and strength, making it suitable for applications with high hygiene requirements. The dairy product pipeline is the core part of the entire system, responsible for conveying dairy products to be sterilized and sterilized. To ensure the quality and safety of the dairy products, the cooling tank 201 can receive fluid from the conveying pipe. A cold liquid pipe 202 is designed on the front side of the cooling tank 201, which is responsible for conveying the cooling medium to the cooling device 203. The front end of the cold liquid pipe 202 is directly connected to the cooling device 203, which ensures that the cooling medium can be quickly and effectively transferred to the cooling device 203, thereby improving cooling efficiency. A recovery pipe 2 is also fixedly connected to the top of the cooling tank 201. 04. The other end of the recovery pipe 204 is connected to the heat exchange tank 205, so that the cooled fluid can be reintroduced into the device for reuse. The top of the cooling hub box 12 is also connected to the right end of the recovery pipe 204 to ensure the smooth flow and circulation of the cooling medium. The right side of the cooling box 201 is also fixed with a fixing plate 206. The fixing plate 206 not only provides additional support, but also facilitates the installation of other components. The right side of the fixing plate 206 is fixedly connected with a fixing folding rod 207, which makes the whole structure more stable. The front right end of the heat exchange tank 205 is connected to the liquid outlet pipe 208, so that the cooled fluid can be smoothly discharged from the device to complete the entire cooling cycle. After sterilization, the milk needs to be cooled by passing cooling water or refrigerant into the cooling box 201 to remove the heat from the milk.

[0043] Please see the appendix Figure 1- Appendix Figure 2 A bracket 14 is fixedly connected to the bottom end of the fixed bending rod 207. A support plate 13 is fixedly connected to the rear left side of the bracket 14. The top of the support plate 13 is fixedly connected to the middle of the outer wall of the raw material cylinder 1. The upper right side of the raw material cylinder 1 is connected to the feed port 20. Support columns 15 are fixedly connected to the four corners of the bottom of the bracket 14. The support columns 15 enhance the stability of the entire structure. The bottom of the multiple support columns 15 is fixedly connected to the base 16. The base 16 provides a solid foundation for the entire device and ensures stable operation under various working conditions.

[0044] Specifically, the pipelines generally use food-grade stainless steel pipes with smooth inner walls, which can reduce the residue of dairy products and bacterial growth in the pipelines. The pipe diameter is usually determined according to the flow rate and production scale of the dairy products. The bottom end of the fixed bending rod 207 is connected to the bracket 14 in a certain way. The left rear end of the bracket 14 is precisely positioned and fixed and tightly connected to the support plate 13. The upper right end of the raw material cylinder 1 is designed with a feed port 20 to facilitate the input of materials. Support columns 15 are installed at the four corners of the bottom of the bracket 14. The support columns 15 enhance the stability of the entire structure and also ensure the stability of the entire device through the fixed connection of their bottoms to the base 16. The base 16 provides a solid foundation for the entire device, ensuring stable operation under various working conditions. In the heat exchanger, heat is transferred to the dairy products in the dairy pipeline through the pipe wall, raising their temperature to achieve the purpose of sterilization. At this time, the dairy products in the dairy pipeline continuously absorb heat during the flow process, and their temperature gradually rises, while the temperature of the heat medium gradually decreases.

[0045] Please see the appendix Figure 2 - Appendix Figure 3 Fixing plates 17 are fixedly connected to the front left side of the bracket 14. The tops of the multiple fixing plates 17 are fixedly connected to the bottom of the outer wall of the filter cylinder 4. Fixing plates 18 are fixedly connected to the front top of the bracket 14. The top of fixing plates 18 is fixedly connected to the bottom of the outer wall of the heat exchange tank 205 to ensure the stability and functionality of the heat exchange tank 205. Support plates 19 are fixedly connected to the rear top of the bracket 14. The top of support plates 19 is fixedly connected to the lower outer wall of the water tank 9. This design further enhances the support and stability of the entire device.

[0046] Specifically, multiple fixing plates 17 are evenly connected on the front left side of the support 14. The top part of the fixing plate 17 is fixedly connected to the bottom of the outer wall of the filter cylinder 4 to ensure the stability of the structure. A fixing plate 18 is also fixedly connected to the front top of the support 14. Its top part is also fixedly connected to the bottom of the outer wall of the heat exchange tank 205 to ensure the stability and functionality of the heat exchange tank 205. A support plate 19 is fixedly connected to the rear top of the support 14. Its top part is also fixedly connected to the lower outer wall of the water tank 9. This design further enhances the support and stability of the entire device. The hot milk after the initial cooling will return to the heat exchange tank 205 through the recovery pipe 204 to transfer heat energy to the cold milk that is about to enter the preheating stage, thereby reducing its own temperature.

[0047] Working principle: When sterilizing dairy products, the raw liquid in the raw material cylinder 1 is first transported to the filter cylinder 4 through the raw material conveying pipe 3. After filtration, it is then transported to the heat exchange hub tank 6 through the first conveying pipe 5, and then to the preheating tank 8 through the second conveying pipe 7. Subsequently, it is heated by the heater 10 to achieve sterilization. Finally, the sterilized dairy products are transported to the cooling hub box 12 through the third conveying pipe 11 for cooling. This process enables continuous filtration and sterilization of dairy products, while also facilitating heat exchange and improving production efficiency.

[0048] After the dairy products are sterilized, the coolant in the cooling device 203 is transported to the cooling tank 201 through the cold liquid pipe 202 to cool the dairy liquid in the cooling hub tank 12. The cooled dairy liquid is then transported to the heat exchange tank 205 through the recovery pipe 204. This allows the cooled dairy products in the heat exchange tank 205 to exchange heat with the dairy products in the heat exchange hub tank 6 that are to be preheated. This maximizes the utilization of the heat of the dairy products at different temperature stages, reduces the input of external energy, and lowers the production cost of the dairy product sterilization process.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
