Detailed Implementation

[0020] This application is based on the findings and understanding of the following facts and issues:

[0021] The current method for detecting the fat content of dairy products involves manual addition of different reagents to the sample and manual shaking. This method is inefficient because it depends on the skill level of the personnel. Furthermore, large-scale processing is labor-intensive and requires highly skilled personnel. In addition, the process of adding reagents and shaking the sample relies on the experience of the personnel, which makes it difficult to guarantee accuracy and consistency. This can easily lead to errors in the test results and affect their accuracy.

[0022] Specifically, some testing equipment in related technologies uses electronically controlled equipment for adding and mixing reagents, and distributes the reagents to multiple test bottles through multi-port valves. On the one hand, the internal passages of multi-port valves are complex, costly, and difficult to clean and maintain. On the other hand, for large-scale testing, multi-port valves cannot have enough passages. Increasing the number of passages will further complicate the structure of multi-port valves, leading to further increased maintenance difficulty and a more complex and cumbersome control process.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] The fat detection device 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0027] like Figure 1 As shown, the fat detection device 1 according to an embodiment of the present invention includes multiple detection containers 10, an oscillation device, a reagent pipeline 20, a turntable 30, a turntable drive device 40, and a dosage control device.

[0028] The oscillation device is adapted to drive the detection container 10 to oscillate. The inlet of the reagent line 20 is connected to the detection reagent source, and the outlet forms a dosing port 21. Multiple detection containers 10 are adapted to be arranged at intervals along the circumference of the turntable 30. The turntable drive device 40 is driven by the turntable 30, and the turntable 30 has multiple dosing positions under the drive of the turntable drive device 40. At each dosing position, one of the multiple detection containers 10 is connected to the dosing port 21. A dosage control device is provided on the reagent line 20.

[0029] Specifically, the detection container 10 is adapted to contain the sample to be tested. For example, the detection container 10 can be a Roots flask to avoid reaction with the sample and the detection reagent.

[0030] The oscillation device can be multiple and is respectively connected to multiple detection containers 10 to drive each detection container 10 to oscillate individually.

[0031] At each of the dosing locations, one of the plurality of detection containers 10 is located directly below the dosing port 21 to accommodate the detection reagent.

[0032] The dosage control device is adapted to control the amount of test reagent entering each test container 10 from the test reagent source.

[0033] Each turntable 30 can be equipped with 50 testing containers 10 to facilitate large-scale testing.

[0034] For example, the dairy samples to be tested are placed in multiple test containers 10, and the multiple test containers 10 are placed on a turntable 30. The turntable driving device 40 drives the turntable 30 to rotate, and the multiple test containers 10 are rotated to the dosing port 21 in sequence. The reagent pipeline 20 adds a quantitative amount of test reagent into the test container 10 under the control of the dosage control device. The oscillation device drives the test container 10 to oscillate, so that the test reagent and the dairy sample are mixed evenly.

[0035] According to the fat detection device 1 of this utility model embodiment, by setting the oscillation device, the detection container 10 can be driven to oscillate by the oscillation device. By setting the dosage control device, the amount of detection reagent added to the detection container 10 can be controlled by the dosage control device. Compared with the related technology that relies on manual addition of reagents and shaking, it can not only reduce the labor intensity of operators and improve detection efficiency, but also facilitate the accuracy and consistency of reagent addition and shaking process, reduce the requirements for operators, reduce the error of detection results, and improve the accuracy of detection results.

[0036] Furthermore, by setting up a turntable 30 and a turntable drive device 40, multiple detection containers 10 can be rotated to the dosing port 21 for dosing, thereby achieving the diversion of detection reagents. Compared with the method of diversion using a multi-port valve in related technologies, the multi-port valve can be eliminated, reducing costs and eliminating the cleaning and maintenance process of the multi-port valve. Moreover, the limitation of the number of passages of the multi-port valve can be avoided, making it convenient for large-scale sample testing.

[0037] Therefore, the fat detection device 1 according to the present invention has the advantages of high detection efficiency, good detection accuracy and consistency, convenient maintenance, and easy large-scale detection.

[0038] The fat detection device 1 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0039] In some specific embodiments of this utility model, such as Figure 1 As shown, the fat detection device 1 according to an embodiment of the present invention includes multiple detection containers 10, an oscillation device, a reagent pipeline 20, a turntable 30, a turntable drive device 40, and a dosage control device.

[0040] Specifically, such as Figure 1 As shown, the fat detection device 1 also includes a constant temperature water tank 60, with at least a portion of each detection container 10 immersed in the constant temperature water tank 60. Specifically, the constant temperature water tank 60 can be adjusted and maintained at the temperature required for detection. This facilitates precise temperature control of the water bath heating of the sample and the detection reagent, ensuring that the fat reacts fully with the detection reagent at a suitable temperature, thereby improving the accuracy of the detection results.

[0041] More specifically, such as Figure 1 As shown, the constant temperature water tank 60 is equipped with a drain valve 61. This allows the water in the constant temperature water tank 60 to be drained using the drain valve 61, and the water level in the constant temperature water tank 60 to be controlled according to the testing requirements.

[0042] Advantageously, the turntable drive unit 40 is equipped with a grating positioning device suitable for positioning the rotational position of the turntable 30. This allows for more precise positioning of the turntable 30 and the detection container 10, ensuring that the detection container 10 is aligned with the dosing port 21 when the turntable 30 is in each dosing position.

[0043] Figure 1 A fat detection device 1 according to some examples of the present invention is shown. For example... Figure 1 As shown, the reagent source includes multiple storage tanks 70, each suitable for storing different reagents. The reagent pipeline 20 includes an outlet pipeline 22 and multiple inlet pipelines 23. The inlets of the multiple inlet pipelines 23 are connected to the multiple storage tanks 70, and the outlets of the multiple inlet pipelines 23 are all connected to the inlets of the outlet pipelines 22, forming a dosing port 21. Specifically, there are four storage tanks 70, including an ammonia tank, an ethanol tank, an anhydrous ether tank, and a petroleum ether tank. The reagents in the four storage tanks 70 can be sequentially added to the detection container 10. This facilitates the addition of different reagents to the detection container 10, meeting the reagent requirements for fat detection.

[0044] Specifically, such as Figure 1 As shown, the dosage control device includes a flow meter 50 installed on each inlet pipe 23. This allows the flow meter 50 to detect the flow rate of the reagent as it flows through, thereby controlling the amount of reagent entering the detection container 10.

[0045] Optionally, such as Figure 1 As shown, each inlet pipe 23 is equipped with a one-way valve 80. This prevents reagents from flowing back into the storage tank 70.

[0046] More specifically, such as Figure 1 As shown, each inlet pipe 23 is equipped with a pumping device 90. This facilitates the delivery of the test reagents from the storage tank 70 to the dosing port 21.

[0047] Advantageously, such as Figure 1 As shown, each storage tank 70 is equipped with a liquid level detection device. Specifically, multiple liquid level detection devices are electrically connected to an alarm device 72, which is adapted to issue an alarm when at least one of the multiple liquid level detection devices detects that the liquid level in the storage tank 70 is lower than a predetermined value. The alarm can be at least one of acoustic and optical alarms. This facilitates the detection of the liquid level in the storage tank 70 and allows for timely replenishment of the detection reagent in the storage tank 70.

[0048] More advantageously, such as Figure 1 As shown, each storage tank 70 is equipped with a pressure balancing valve 71. Specifically, the pressure balancing valve 71 is adapted to be connected to the atmosphere. This allows the pressure difference between the inside and outside of the storage tank 70 to be balanced in a timely manner when the pumping device 90 delivers the test reagents inside the storage tank 70, making the reagent delivery smoother.

[0049] Specifically, the fat detection device 1 also includes a reagent box 100, with multiple storage tanks 70 located inside the reagent box 100. The reagent box 100 is equipped with a reagent control panel 101, which can be electrically connected to multiple flow meters 50 and multiple pumping devices 90 to facilitate the setting and control of reagent addition, such as the order of reagent addition, addition time, and addition amount.

[0050] The fat detection device 1 also includes a detection chamber 110, on which a turntable 30, a turntable drive device 40, an oscillation device, and a constant temperature water tank 60 are all mounted. The detection chamber 110 is equipped with a detection control panel 111, which is electrically connected to the turntable drive device 40, the oscillation device, the constant temperature water tank 60, and the drain valve 61, respectively, so as to set and control the position of the detection container 10, the oscillation process, the water bath heating temperature, and the water level, such as the start and stop of the oscillation device and the running time, and the opening and closing of the drain valve 61.

[0051] Other components and operations of the fat detection device 1 according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
