It should be noted that like reference numerals and letters refer to like items in the following drawings, and thus, once an item is defined in one drawing, it need not be discussed further in subsequent drawings.

[0034] As Figures 1 to 3As shown in the embodiment, the liquid dairy product quality monitoring and analyzing device comprises a stirring tank 10, a first communication pipe 20, a sample container 30, a second communication pipe 40, a detection structure 50, and a controller. The stirring tank 10 is provided with a stirring element 11, and has a test outlet 12 and a reflux port 13. The first end of the first communication pipe 20 is in communication with the test outlet 12. The inlet of the sample container 30 is in communication with the second end of the first communication pipe 20. The second communication pipe 40 is in communication between the outlet of the sample container 30 and the reflux port 13. The detection structure 50 is used for detecting the uniformity of the sample in the sample container 30. The controller is electrically connected with the stirring element 11 and the detection structure 50.

[0035] By applying the technical scheme of the embodiment, the stirring tank 10 is provided with the stirring element 11, so that the dairy product can be stirred in the stirring tank 10. The first communication pipe 20 is in communication between the test outlet 12 and the sample container 30, and the second communication pipe 40 is in communication between the sample container 30 and the reflux port 13. The detection structure 50 is used for detecting the uniformity of the sample in the sample container 30, and the controller is electrically connected with the stirring element 11 and the detection structure 50. Through the above arrangement, the dairy product can be fully mixed in the stirring tank 10, and can be sampled and refluxed under the action of the first communication pipe 20 and the second communication pipe 40. The detection structure 50 can realize the mixing uniformity detection of the dairy product in the sample container 30, which effectively improves the detection efficiency and avoids the waste of the sample. The controller can control the stirring element 11 according to the detection signal of the detection structure 50, that is, when the detection structure 50 detects that the mixing uniformity of the dairy product is qualified, the controller immediately controls the stirring element 11 to stop working, thereby avoiding the over-mixing of the dairy product. Therefore, the technical scheme of the embodiment effectively solves the problem of low mixing uniformity detection efficiency of the dairy product in the related art, which affects the production efficiency.

[0036] It should be noted that the "liquid dairy product quality" in the embodiment refers to the mixing uniformity of the liquid dairy product.

[0037] As shown in the embodiment, the sample container 30 is provided with a detection window 31, and the detection structure 50 is a near-infrared spectrometer 51, which is arranged corresponding to the detection window 31. Figures 1 to 3 The near-infrared spectrometer 51 can quickly and non-destructively detect the quality of the dairy product sample, especially the uniformity thereof, which is crucial for the quality control of the dairy product, can real-time feedback the mixing effect of the dairy product, ensures the consistency of the quality of the dairy product, and is suitable for the dairy product production environment which needs high-frequency detection.

[0038] It should be noted that the detection window 31 is provided with a sapphire window, which has high transmittance for near-infrared light. The sample container 30 is also provided with an observation window, which is spaced apart from the detection window 31, and which can realize detection of the dairy product in the sample container 30. Specifically, the observation window and the detection window 31 are respectively arranged on opposite sides of the sample container 30.

[0039] Specifically, the lens of the near-infrared spectrometer 51 and the sapphire window of the detection window 31 are coaxial, and when collecting near-infrared spectral data of the sample, the lens of the near-infrared spectrometer 51 and the sapphire window of the detection window 31 are both close.

[0040] Further, the use of the near-infrared spectrometer 51 makes the detection process more environmentally friendly and energy-saving, i.e. without the use of chemical reagents, avoiding pollution to the environment. At the same time, the high-frequency detection capability is extremely important for the quality management of dairy factories, which can timely discover and solve the fluctuation problem of dairy product quality, ensure that each tank of dairy product can meet the high-standard quality requirements, and is suitable for high-end dairy processing with strict quality requirements.

[0041] As shown in Figures 1 to 3 In this embodiment, the liquid dairy product quality monitoring and analysis device further comprises a pump body 71 arranged on the first communication pipe 20. The introduction of the pump body 71 makes the sampling process of the dairy sample more automated, improves the continuity of sampling and detection, reduces the error of manual operation, and is suitable for continuous production monitoring of large-scale dairy factories.

[0042] Specifically, the automated sampling of the pump body 71 not only improves the accuracy of detection, but also greatly reduces the labor intensity of workers, reduces the quality problems caused by improper manual operation, and enables the dairy factory to realize 24-hour uninterrupted quality detection.

[0043] As shown in Figures 1 to 3 In this embodiment, the liquid dairy product quality monitoring and analysis device further comprises a heat dissipation structure 72 arranged outside the detection structure 50. The arrangement of the heat dissipation structure 72 ensures the temperature stability of the detection structure 50 during work, avoids the influence of high temperature on the accuracy of the detection result, and is suitable for dairy product quality detection under various temperature conditions.

[0044] The heat dissipation structure 72 can realize heat dissipation in a high-temperature environment, i.e. the heat dissipation structure 72 can ensure that the detection structure 50 still maintains the best working state in a high-heat production environment, avoids the detection result deviation caused by temperature fluctuation, and thus ensures the reliability and stability of the dairy product quality detection.

[0045] As shown in Figures 1 to 5As shown, in this embodiment, the heat dissipation structure 72 includes a heat dissipation block 721 and a heat dissipation fan 722. The heat dissipation block 721 is arranged below the detection structure 50, and the heat dissipation fan 722 is located on the side of the heat dissipation block 721. The combination of the heat dissipation block 721 and the heat dissipation fan 722 can effectively reduce the temperature of the detection structure 50 and improve the stability of detection. It is suitable for dairy production lines that require long-term continuous detection.

[0046] This heat dissipation design not only extends the life of the detection structure 50 but also ensures the accuracy of dairy product quality detection during long periods of continuous operation. In practical applications, such as quality monitoring on a continuous dairy production line, the heat dissipation structure 72 can effectively prevent equipment overheating due to continuous operation, ensuring the stable operation of the detection structure 50.

[0047] like Figure 4 and Figure 5 As shown, in this embodiment, the heat sink 721 is a semiconductor refrigeration block. Using a semiconductor refrigeration block as the heat sink 721 can not only achieve rapid cooling, but also has low energy consumption and low maintenance costs, and is suitable for dairy production environments that pursue high efficiency and energy saving.

[0048] The high efficiency and energy saving characteristics of semiconductor refrigeration blocks are particularly suitable for dairy factories that have strict requirements on energy consumption and environmental protection, thereby effectively reducing overall production costs.

[0049] like Figure 4 and Figure 5 As shown, in this embodiment, the liquid dairy product quality monitoring and analysis device further includes a support structure 73, a heat sink 721 is movably disposed on the support structure 73, and the detection structure 50 is disposed on the heat sink 721. By moving the support structure 73, the detection structure 50 can be adjusted as needed.

[0050] like Figure 4 and Figure 5 As shown, in this embodiment, the support structure 73 includes a support base 731 and a sliding base 732. The heat sink 721 is disposed on the sliding base 732, and a guide structure 733 is disposed between the support base 731 and the sliding base 732. The provision of the guide structure 733 ensures smooth movement of the heat sink 721 and the detection structure 50, thereby improving detection accuracy. Specifically, when the mixing tank 10 needs to be sterilized at high temperature, the detection structure 50 can be moved away from the sample container 30 to prevent damage to the detection structure 50.

[0051] like Figure 4 and Figure 5 As shown, in this embodiment, the introduction of the guide structure 733 not only improves the stability and accuracy of the movement of the detection structure 50.

[0052] likeFigure 4 and Figure 5 As shown, in this embodiment, the detection structure 50 further includes a plurality of light sources 52, which are arranged in an array around the periphery of the near-infrared spectrometer 51. The arrangement of the plurality of light sources 52 can provide more uniform illumination and improve the accuracy and reliability of detection.

[0053] Specifically, the design of an array of multiple light sources 52, with eight light sources 52, can provide more uniform illumination and, to a certain extent, compensate for uneven illumination caused by the positional variations of the sample container 30, thereby improving the consistency of test results. For dairy product quality testing, the stability and uniformity of illumination conditions directly impact the accuracy of test results.

[0054] It should be noted that the light source 52 is preferably a halogen tungsten lamp.

[0055] like Figures 1 to 3 As shown, in this embodiment, the liquid dairy product quality monitoring and analysis device also includes a rehydration tank 81, a rehydration tube 82 and a control valve 83. The rehydration tube 82 is connected between the rehydration tank 81 and the mixing tank 10. The control valve 83 is arranged on the rehydration tube 82, and the control valve 83 is electrically connected to the controller. The introduction of the rehydration tank 81 and the control valve 83 realizes the automatic rehydration of the dairy product. The various nutrients that need to be added are stored in the rehydration tank 81. The controller controls the opening or closing of the control valve 83. The various nutrients enter the mixing tank 10 through the rehydration tube 82 and are mixed under the drive of the stirring element 11. The automatic rehydration system can intelligently rehydrate according to the consumption of the dairy product in the mixing tank 10, avoid the interruption of the production line due to insufficient dairy products, and improve production continuity and efficiency.

[0056] like Figures 1 to 3As shown, in the present embodiment, the pump body 71 draws the liquid dairy sample in the stirring tank 10 out through the first communication pipe 20 into the sample container 30. The observation window at the top of the sample container 30 can prevent the liquid dairy sample from overflowing, and the sapphire window at the bottom of the sample container 30 has high transmittance to near-infrared light; the near-infrared spectrometer 51 and the sapphire window are coaxial, the high-power light source 52 emits near-infrared light which irradiates the liquid dairy sample in the sample container 30 through the sapphire window; the near-infrared spectrometer 51 receives the near-infrared light which is diffusely reflected back to the near-infrared spectrometer 51 after being absorbed by the liquid dairy sample, and converts the received near-infrared light signal into an electrical signal through the photoelectric conversion module inside the near-infrared spectrometer 51 and transmits it to the controller through wired or wireless mode for data storage and processing, thereby ensuring that the collected near-infrared spectrum has high signal-to-noise ratio. The detection structure 50 is installed on the heat dissipation structure 72, the heat dissipation block 721 cools the detection structure 50, and the heat dissipation fan 722 enhances the cooling effect, thereby ensuring the stability of the near-infrared spectrum data collected by the near-infrared spectrometer 51. The detection structure 50 and the heat dissipation block 721 are fixed on the sliding seat 732, which can drive the detection structure 50 and the heat dissipation block 721 away from the sample container 30 when the stirring tank 10 is subjected to high-temperature sterilization, thereby protecting the detection structure 50 from high temperature damage. The controller can be connected to a local area network and realize cloud data storage, within the coverage range of the local area network, the staff can realize the functions of controlling the device, storing data, calling models, and analyzing data through the controller, thereby can not be limited by the operation place within a certain space range, effectively improving and ensuring the automation degree and continuity of the technical solution of the present embodiment, and can avoid the staff entering the noisy and high-temperature working environment.

[0057] The detection structure 50 transmits the near-infrared spectrum data to the controller in wired or wireless mode; the controller can be connected to a local area network and realize cloud data storage, within the coverage range of the local area network, the staff can realize the functions of controlling the device, storing data, calling models, and analyzing data through the controller.

[0058] Specifically, the present scheme ensures uniform mixing of the dairy product in the stirring tank 10 by providing the stirring element 11, and realizes automatic sampling and backflow of the dairy product sample through the first communication pipe 20 and the second communication pipe 40, avoiding sample waste and improving detection efficiency.

The provision of the heat dissipation structure 72 and the support structure 73 ensures the stability of the detection structure 50 and the suitability of the detection environment, further improving the accuracy and reliability of the detection. The introduction of the pump body 71 and the control valve 83 realizes automatic control and liquid replenishment of the dairy product sample, improving the automation level and operation convenience of the device. The entire device is designed reasonably, with high automation degree and accurate detection, effectively improving the efficiency and precision of liquid dairy product quality monitoring, and has significant benefits for production quality control in the dairy industry. In addition, the device can be upgraded as needed, such as adding data recording and analysis functions, realizing remote monitoring and adjustment, and further improving the intelligent level of the dairy production process. The liquid dairy product sample is mixed in the stirring tank 10 under the driving of the stirring element 11, and the required various nutritional ingredients are stored in the liquid replenishment tank 81. The controller controls the opening or closing of the control valve 83, and the various nutritional ingredients enter the stirring tank 10 through the liquid replenishment pipe 82 and are fully mixed under the driving of the stirring element 11. The pump body 71 draws out the liquid dairy product sample in the stirring tank 10 and enters the sample container 30 through the first communication pipe 20.

The near-infrared spectrometer 51 is installed on the heat dissipation block 721, which cools and cools the near-infrared spectrometer 51, and combines with the cooling fan 722 to enhance the cooling effect, thereby ensuring the stability of the near-infrared spectrum data collected by the near-infrared spectrometer 51. The near-infrared spectrometer 51 and the heat dissipation block 721 are fixed to the sliding seat 732, which can drive the near-infrared spectrometer 51 and the heat dissipation block 721 away from the sample container 30 during high-temperature disinfection of the liquid dairy product quality online monitoring and analysis device in this embodiment, thereby protecting the near-infrared spectrometer 51 from high temperature damage.The controller can be connected to a local area network and realize cloud data storage, within the coverage range of the local area network, the staff can realize the functions of controlling the device, storing data, calling the model and analyzing the data through the controller, so that the automation degree and continuity of the online monitoring and analyzing device for a liquid dairy product quality can be effectively improved and ensured within a certain spatial range (within the coverage range of the local area network), and the staff can be prevented from entering a noisy and high-temperature working environment, and the comfort degree of the labor process is improved.
