Description

Technical Field

[0001] The utility model relates to the technical field of wine detection, and more specifically to a detection device for harmful substances in wine. Background Art

[0002] The wine harmful substance detection device is a device used to detect the methanol content in wine. The methanol content is very easy to exceed the standard when brewing wine. High concentration of methanol intake may cause harm to human health. Therefore, monitoring the methanol content in wine is very important to ensure the quality and safety of wine.

[0003] Chinese Patent Authorization Announcement No.: CN219810734U provides a wine flavor substance detection device. The solution is provided by setting a separation tube, a first switch valve, a guide tube and a weighing device. The heating device heats the heating bottle. At this time, only the first switch valve located at a lower position is in an open state. The separated flavor substances are collected and guided to the weighing device through the guide tube. When the weighing device collects a certain amount of substances, the weighing device that receives the flavor substances will close the corresponding first switch valve through the controller, and at the same time, it will open the first switch valve above the closed first switch valve. Then the heating device increases the heating temperature, so that new flavor substances will be generated. And so on, so that the device can prevent mixing when collecting flavor substances, and can also realize automatic separation of multiple flavor substances in wine.

[0004] The above scheme cannot detect methanol in wine. When brewing wine, especially when brewing wine at home, there is a risk of exceeding the methanol content in the wine. Methanol is metabolized in the human body to produce formic acid and formaldehyde. Excessive intake of methanol can cause symptoms such as headache and dizziness. Therefore, a detection device for harmful substances in wine is proposed to address the above problem. Utility Model Content

[0032] Example:

[0033] See also Figure 1-Figure 3 A detection device for harmful substances in wine includes a liquid mixing component 1, a stirring component 2 and a plurality of measuring cylinders 5. A fixing frame 6 is arranged at the bottom of the liquid mixing component 1, a sealing ring 7 is arranged between the liquid mixing component 1 and the fixing frame 6, and a mounting component 4 is arranged at the bottom of the fixing frame 6. The liquid mixing component 1 includes a collar 11 and a liquid mixing cylinder 12. The outer end of the liquid mixing cylinder 12 is fixedly connected to the collar 11, and the outer end of the collar 11 is engraved with anti-slip patterns.

[0034] The stirring assembly 2 includes a handle 21 and a plurality of stirring blades 22 . The bottom end of the handle 21 is fixedly connected to the stirring blades 22 . The plurality of stirring blades 22 are distributed in a ring shape. The outer ends of the stirring blades 22 are provided with a plurality of through holes.

[0035] This scheme is mainly to detect methanol in wine. Grapes contain a large amount of pectin. During the alcohol fermentation process, yeast and alcohol will decompose most of the pectin, and the remaining pectin will be slowly decomposed by the pectinase of the grape fruit. At this time, methanol will be generated, which is the main source of methanol in wine. The device is mainly used to stir the wine, dilution water and oxidant. When testing, the wine needs to be diluted first. The wine and deionized water are poured into the mixing cylinder 12 in a ratio of 1:9. At this time, an appropriate amount of oxidant is added. The oxidant is mainly composed of potassium permanganate phosphoric acid solution. After that, it needs to be stirred evenly. The methanol in the wine is oxidized into formaldehyde by potassium permanganate in the phosphoric acid solution. The stirring component 2 is mainly composed of a plurality of stirring blades 22 and a handle 21. When in use, the handle 21 needs to be held to make the stirring blade 22 rotate and stir in the mixing cylinder 12 to stir the solution evenly.

[0036] Then it can be put into the measuring cylinder 5, the measuring cylinder 5 is installed on the mounting assembly 4, and the mounting assembly 4 is fixed to the bottom end of the fixing frame 6. At this time, pinch the ring 11 and rotate it to make the first liquid outlet on the mixing cylinder 12 coincide with the second liquid outlet on the mounting disk 64, so that the solution can flow into multiple measuring cylinders 5 evenly. Mounting grooves for mounting the sealing ring 7 are provided on the mounting disk 64 and the mixing cylinder 12, so that the sealing ring 7 can be installed between the mounting disk 64 and the mixing cylinder 12, which can increase the sealing performance and the friction during rotation to prevent the mixing cylinder 12 from rotating by itself.

[0037] Then the decolorizing agent can be dropped into multiple measuring cylinders 5 respectively. The decolorizing agent is mainly composed of oxalic acid and sulfuric acid solution. The excess potassium permanganate added before and the manganese dioxide produced in the reaction can be removed with sulfuric acid and oxalic acid solution to make the solution transparent. Then the color developer is added and shaken evenly. The color developer is mainly composed of fuchsin sulfite solution. The formaldehyde generated before reacts with fuchsin sulfite to generate blue-purple quinone-type pigment. At this time, you only need to compare the color of the solution with the standard color card to get the methanol content in the wine, so that users can operate it at home. The methanol content can be detected through simple operation, which reduces the cost of detection and improves the convenience of use.

[0038] See also Figure 2 and Figure 3 The fixing frame 6 includes a mounting ring 61, a limiting ring 62 is fixedly connected to the inner side of the mounting ring 61, a plurality of telescopic springs 63 equidistantly distributed in an annular shape are fixedly connected to the inner side of the mounting ring 61, and a plurality of brackets 3 are fixedly connected to the bottom end of the mounting ring 61.

The top end of the connecting rod 41 is fixedly connected to the bottom end of the mounting disk 64. The outer end of the mounting plate 42 is provided with a plurality of clamping grooves matching the measuring cylinder 5. The measuring cylinder 5 abuts against the inner wall of the clamping groove.

[0042] The mixing liquid cylinder 12 in this scheme is mainly connected with the limiting ring 62 on the mounting ring 61 through the limiting groove opened on the outside, so that the mixing liquid cylinder 12 can be rotated while being installed on the mounting ring 61. The mounting plate 64 is tightly abutted against the bottom end of the mixing liquid cylinder 12. At the same time, a plurality of telescopic springs 63 are installed at the bottom edge of the mounting plate 64. The mounting plate 64 can be pushed upward by the force of the telescopic springs 63, so that it can abut more tightly against the bottom of the mixing liquid cylinder 12, thereby increasing the sealing performance. A plurality of brackets 3 are fixed to the bottom end of the mounting ring 61 for support. The connecting rod 41 is fixed to the bottom end of the mounting plate 64 near the center. The bottom end of the connecting rod 41 is fixed with a mounting plate 42. The outer edge of the mounting plate 42 is provided with a plurality of clamping grooves, and the measuring cylinder 5 can be installed on the clamping groove, so that the first liquid outlet on the mounting plate 64 can face the measuring cylinder 5, which is convenient for the solution to flow into the measuring cylinder 5, thereby making the solution flow into a plurality of measuring cylinders 5 evenly, and taking the average value after detection to improve the detection accuracy.

[0043] Working principle: When using the device for testing, the wine needs to be diluted first. Pour the wine and deionized water into the mixing tube 12 in a ratio of 1:9. Then take an appropriate amount of oxidant and add it. The oxidant is mainly composed of potassium permanganate phosphoric acid solution. The methanol in the wine is oxidized into formaldehyde by potassium permanganate in the phosphoric acid solution. Hold the handle 21 to rotate and stir the stirring blade 22 in the mixing tube 12 to stir the solution evenly. Then pinch the ring 11 and rotate it to make the first liquid outlet on the mixing tube 12 coincide with the second liquid outlet on the mounting plate 64, so that the solution Evenly flow into multiple measuring cylinders 5, and then the decolorizing agent can be dropped into multiple measuring cylinders 5 respectively. The decolorizing agent is mainly composed of oxalic acid and sulfuric acid solution. The excess potassium permanganate added before and the manganese dioxide produced in the reaction can be removed with sulfuric acid and oxalic acid solution to make the solution transparent. Then the color developer is added and shaken evenly. The color developer is mainly composed of magenta sulfite solution. The formaldehyde generated before reacts with magenta sulfite to generate blue-purple quinone-type pigment. At this time, you only need to compare the color of the solution with the standard color card to get the methanol content in the wine.
