Description

Technical Field

[0001] This utility model relates to the field of dairy processing technology, and in particular to a sterilization device for dairy product filling. Background Technology

[0002] Dairy products, as an important part of the human diet, are not only rich in high-quality protein, calcium, and various vitamins, but also beloved by consumers for their unique taste and nutritional value. From milk and yogurt to cheese and butter, the sterilization process is crucial in dairy production. Sterilization not only effectively eliminates harmful microorganisms such as bacteria and viruses in raw milk, ensuring product safety, but also extends the shelf life of dairy products, maintaining their original flavor and nutritional value, which is of great significance for improving product quality and consumer health.

[0003] Currently, there are various sterilization devices for dairy products on the market. Among them, a dairy product sterilization tank with rapid cooling function, with announcement number CN221829943U, includes a sterilization tank body and a feed pipe fixed on its top. It also includes a stirring shaft rotatably connected to the inner wall of the sterilization tank body. Stirring rods are staggered on both sides of the stirring shaft. A drive motor is fixedly connected to the top of the sterilization tank body. The output shaft of the drive motor is fixedly connected to the end of the stirring shaft. The stirring rods drive the scraper to slide along the inner wall of the sterilization tank body, which first provides a stirring effect on the dairy products, improving the overall efficiency of the sterilization process. It can also scrape off the dairy products adhering to the inner wall of the sterilization tank body, effectively preventing the dairy products from coagulating on the inner wall of the sterilization tank body later.

[0004] However, some shortcomings still exist in actual operation, especially in the heating and cooling processes, where the consumption of water resources and energy is particularly prominent. In the heating stage, in order to maintain the required sterilization temperature, the large amount of hot water passing through at one time increases the water consumption and also leads to high energy expenditure for heating. Similarly, the consumption of cooling media used in the cooling process, such as cold water or refrigerant, is also not negligible, further increasing production costs and environmental burden. Utility Model Content

[0005] To overcome the drawbacks of high resource and energy consumption, this utility model provides an energy-saving sterilization device for dairy product filling.

[0006] A sterilization device for dairy product filling includes a sterilization tank, a cold water tank, a hot water tank, a first inlet pipe, and a second inlet pipe. A temperature control pipe is installed inside the side wall of the sterilization tank. The cold water tank and the hot water tank are located in front of the sterilization tank, and each tank has a water inlet. One end of the first inlet pipe is connected to the cold water tank, and the other end is connected to the sterilization tank, with a first control valve installed in the middle. One end of the second inlet pipe is connected to the hot water tank, and the other end is connected to the sterilization tank, with a second control valve installed in the middle. A return pipe is connected to the bottom of the sterilization tank, and the other end of the return pipe is connected to the rear ends of both the cold water tank and the hot water tank. A third control valve is installed at the end of the return pipe connected to the cold water tank, and a fourth control valve is installed at the end connected to the hot water tank. A controller is installed on the cold water tank, and the controller is wired to all control valves and the temperature control pipe. A heat dissipation mechanism for accelerating liquid cooling is provided on the cold water tank.

[0007] As a preferred technical solution of this utility model, the heat dissipation mechanism includes an exhaust fan. An exhaust fan is installed on the cold water tank. A discharge pipe is connected to the top of the exhaust fan. A housing is connected in the middle of the discharge pipe. A filter box is slidably connected inside the housing. Activated carbon is placed inside the filter box.

[0008] As a preferred embodiment of this utility model, a filter screen is connected to the end of the discharge pipe.

[0009] As a preferred embodiment of this utility model, the filter box is connected to a handle.

[0010] As a preferred embodiment of this utility model, the cold water tank and the hot water tank are provided with a transparent observation window on the front side.

[0011] As a preferred embodiment of this utility model, the cold water tank and the hot water tank are connected to brackets, and the top of the brackets are respectively connected to the first water inlet pipe and the second water inlet pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. Through the integrated design of the temperature control tube and the hot water tank, and the precise control of the hot water circulation flow, which is completed by the controller, the second control valve and the fourth control valve, the waste of hot water is effectively reduced, the utilization efficiency of thermal energy is improved and the energy consumption is reduced.

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0020] Example: A sterilization device for filling dairy products, such as Figures 1-3 As shown, the system includes a sterilization tank 1, a temperature control pipe 2, a cold water tank 3, a hot water tank 31, a controller 32, a first water inlet pipe 4, a second water inlet pipe 41, a first control valve 5, a second control valve 51, a return pipe 6, a third control valve 7, a fourth control valve 71, and a heat dissipation mechanism. A mesh-like temperature control pipe 2 is connected to the inner side wall of the sterilization tank 1. A cold water tank 3 and a hot water tank 31 are located in front of the sterilization tank 1. A vent 33 is located on the top of the hot water tank 31. Water inlets 34 are located on the front sides of both the cold water tank 3 and the hot water tank 31. Water is added through the water inlets 34 before sterilization and cooling to ensure sufficient water content in the cold water tank 3 and the hot water tank 31 to fill the space on the side wall of the sterilization tank 1. One end of the first water inlet pipe 4... The first control valve 5 is installed in the middle of the cold water tank 3 and the other end is connected to the top of the sterilization tank 1. The second water inlet pipe 41 is connected to the hot water tank 31 at one end and the other end is connected to the top of the sterilization tank 1. The second control valve 51 is installed in the middle of the second water inlet pipe 41. The bottom of the sterilization tank 1 is connected to the return pipe 6. The other end of the return pipe 6 is forked and connected to the rear end of the cold water tank 3 and the hot water tank 31 respectively. The end of the return pipe 6 connected to the cold water tank 3 is equipped with a third control valve 7, and the end connected to the hot water tank 31 is equipped with a fourth control valve 71. The cold water tank 3 is equipped with a controller 32. The controller 32 is wired to all control valves and the temperature control pipe 2. The cold water tank 3 is equipped with a heat dissipation mechanism for accelerating liquid cooling.

[0021] like Figure 1and Figure 3 As shown, the heat dissipation mechanism includes an exhaust fan 8, a discharge pipe 9, a housing 10, a filter box 11, and activated carbon 12. An exhaust fan 8 is installed on the cold water tank 3. The top of the exhaust fan 8 is connected to the discharge pipe 9. The middle of the discharge pipe 9 is connected to the housing 10. The filter box 11 is slidably connected inside the housing 10. Activated carbon 12 is placed inside the filter box 11.

[0022] The staff pours the dairy products to be sterilized into sterilization tank 1. Then, the controller 32 sets the temperature of the hot water tank 31 and the temperature control tube 2. After heating to the set temperature, the second control valve 51 is opened, and hot water flows into sterilization tank 1 through the second inlet pipe 41, making full contact with the built-in mesh temperature control tube 2 to maintain the internal temperature of sterilization tank 1. The mesh temperature control tube 2 ensures uniform heating throughout sterilization tank 1. When the side wall of sterilization tank 1 is full of hot water, the controller 32 opens the fourth control valve 71, with the flow rates of the second control valve 51 and the fourth control valve 71 being the same. Hot water flows back into the hot water tank 31 through the return pipe 6 at the bottom of sterilization tank 1, ensuring that the hot water in sterilization tank 1 is full and flowing, further optimizing the uniformity of heating. After sterilization is complete, the heating function of temperature control tube 2 is turned off. Yes, and close the hot water tank 31 and the second control valve 51. The hot water in the side wall of the sterilization tank 1 flows back to the hot water tank 31 through the return pipe 6 and closes the fourth control valve 71. When cooling the raw materials, the first control valve 5 is opened through the controller 32. Cold water flows into the side wall of the sterilization tank 1 through the first water inlet pipe 4 to cool the raw materials in the sterilization tank 1. When the water is full, the third control valve 7 is opened. The water flows into the cold water tank 3 through the return pipe 6 and the exhaust fan 8 is turned on to dissipate heat. When the cold water circulates into the side wall of the sterilization tank 1, the temperature can be kept low enough. After the cooling is completed, the first control valve 5 is closed. After the cold water has completely returned, the third control valve 7 is closed. Finally, the exhaust fan 8 is turned off. The water in the cold water tank 3 and the hot water tank 31 can be used continuously. After consumption, it can be replenished in time through the water inlet 34.

[0023] It should be emphasized that after the exhaust fan 8 is turned on, the airflow is drawn out from the top of the cold water tank 3, passes through the activated carbon 12 in the filter box 11, and is discharged from the exhaust pipe 9. The activated carbon 12 can absorb harmful substances in the airflow to ensure the safety of gas emission. After working for a period of time, pull out the filter box 11 and replace the activated carbon 12.

[0024] like Figure 3 As shown, it also includes a filter screen 13, and the end of the discharge pipe 9 is connected to the filter screen 13.

[0025] The filter 13 can not only effectively filter out impurities and particles in the exhaust gas to ensure the cleanliness of the gas, but also act as a barrier to prevent foreign objects from entering the interior of the cold water tank 3 through the exhaust pipe 9, thereby protecting the cleanliness of the device.

[0026] like Figure 3 As shown, it also includes a handle 14, which is connected to the filter box 11.

[0027] Using this handle 14, users can easily pull the filter box 11 to replace the activated carbon 12.

[0028] like Figure 1 and Figure 2 As shown, it also includes an observation window 15, and the cold water tank 3 and the hot water tank 31 are provided with an observation window 15 made of transparent material.

[0029] Through the observation window, users can clearly see the water level changes in the cold water tank 3 and the hot water tank 31, so as to replenish the water in time and ensure that the water in the cold water tank 3 and the hot water tank 31 can always fill the space on the side wall of the sterilization tank 1.

[0030] like Figure 1 As shown, it also includes a bracket 16. The bracket 16 is connected to the cold water tank 3 and the hot water tank 31. The top of the bracket 16 is connected to the first water inlet pipe 4 and the second water inlet pipe 41, respectively.

[0031] The support structure 16 is stable and can effectively reduce the shaking of the inlet pipe, ensuring smooth water flow and safe operation of the system.

[0032] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
