Description

Technical Field

[0001] The utility model relates to the technical field of pigment detection, in particular to a device for rapid detection of pigments in beverages. Background Art

[0002] Artificial synthetic pigments are often used as additives and added to various beverages to give the beverages a bright color and improve their taste and appearance. Professor Wu Hongjing and others published a paper titled "Rapid Detection Method of Synthetic Pigments Based on Test Paper and Its Application in Soft Drinks", proposing the use of prepared pigment test paper to detect whether the corresponding pigment is contained. In the existing technology, direct determination and post-adsorption determination methods are generally used to accurately detect the types and contents of pigments contained in beverages. However, in actual applications, due to the large number of operating steps commonly used for pigment detection methods, the waiting time required to obtain the test results is too long. When encountering a situation where only the presence of pigments is required, it is difficult to achieve the purpose of rapid detection using the above-mentioned detection process, and multiple devices need to be used to complete the detection steps during the detection process, which is not convenient for practical application. To this end, we proposed a rapid detection device for pigments in beverages. Utility Model Content

[0021] Furthermore, the mounting plate 2 is provided with a socket 5 for cooperating with the sample cartridge 6. A limit ring is fixed to the top of the sample cartridge 6. A movable opening 9 is provided on the edge of the mounting plate 2 and communicates with the socket 5. The movable opening 9 is engaged with the guide groove 7. After the test is completed, the sample cartridge 6 can be lifted upward to disengage the guide groove 7 from the movable opening 9 and the mounting plate 2. The sample cartridge 6 can then be moved upward from the socket 5, thereby completely separating the sample cartridge 6 and the mounting plate 2 for easy cleaning.

[0022] Specifically, by setting up a base plate 1, a mounting plate 2, a test paper storage box 25 and a detection mechanism, the collected beverage sample is dripped into the sample tube 6 through a syringe or a dropper and other instruments, and the beverage sample flows into the soaking tank 8 through the guide groove 7 and accumulates in the soaking tank 8. Then the test paper in the test paper storage box 25 is taken out and placed in the soaking tank 8 where the sample to be tested is located, so that the test paper is soaked in the beverage sample. After a period of time, the test paper shows color, which indicates that the beverage sample contains pigment. Compared with the existing technology, it only detects whether the beverage contains pigment, which can achieve the effect of rapid detection, save time, and has efficient detection. There is no need to use a variety of different equipment for detection, which is convenient for detection. In addition, the utility model is relatively small in size, compact in structure, easy to carry and easy to use.

[0023] A clamping assembly is provided on both sides of the soaking tank 8, and the clamping assembly includes a clamping rod 10 elastically connected to the soaking tank 8;

[0024] Furthermore, mounting seats 11 are fixed on both sides of the immersion tank 8, and the clamping rod 10 is connected to the mounting seats 11 through a rotating shaft 12. A torsion spring 13 is sleeved on the rotating shaft 12, with both ends fixed to the mounting seat 11 and the clamping rod 10 respectively; the elastic force of the torsion spring 13 is used to tighten the clamping rod 10, so that the two ends of the test paper are clamped by the clamping rod 10, so that the test paper can be taken out later;

[0025] Furthermore, a pin 14 is provided on the outside of the immersion tank 8, a clip 15 is installed on the top of the pin 14, a pair of rings 16 fixed to the outer wall of the immersion tank 8 are sleeved on the pin 14, and a limiting sleeve 18 is provided between adjacent rings 16 and is sleeved on the pin 14 and fixed to the immersion tank 8. A limiting rod 17 is fixed on the pin 14, and an adjustment port 19 is opened on the limiting sleeve 18 to match the limiting rod 17;

[0026] Specifically, after the test paper has been soaked for a period of time, it will carry a lot of liquid. If the test paper is taken out directly at this time, the beverage sample will drip outside the soaking tank 8. The pin 14 can be pulled upward to make the limit rod 17 pass through the adjustment port 19 into the gap between the upper ring sleeve 16 and the limit sleeve 18. The pin 14 can be rotated again to move the spool 14 upward, thereby driving the clip 15 to move upward. The clip 15 can be used to clamp the test paper to keep the test paper away from the beverage sample and drain the liquid it carries.

[0028] Furthermore, a carrier plate 20 is fixed to the side of the support rod 3, and the color cards 21 are evenly arranged on the carrier plate 20, and the color cards 21 are bonded to the carrier plate 20 by an adhesive;

[0029] Specifically, by providing a color comparison mechanism, the color test paper and the color comparison card 21 can be compared one by one, thereby roughly determining the pigment content range, which is beneficial for further detection.

[0030] A dust cover 28 is provided on the outside of the base plate 1 and the mounting plate 2 to prevent dust from entering the sample tube 6, the guide groove 7 and the soaking tank 8, thereby preventing dust from affecting the reaction between the test paper and the beverage sample;

[0031] Furthermore, a connecting post 4 is fixed between the base plate 1 and the middle of the mounting plate 2, penetrating the latter. A connecting cylinder 29 is fixed to the top of the dust cover 28, which is threadedly connected to the connecting cylinder 4. A limit ring 27 is fixed to the connecting cylinder 4. By rotating the connecting cylinder 29, the dust cover 28 and the connecting cylinder 4 can be locked, thereby stably connecting the dust cover 28 to the mounting plate 2, achieving a good dustproof effect. The limit ring 27 is used to limit the distance the dust cover 28 can move downward.

[0032] Furthermore, a storage cylinder 22 is connected through the mounting plate 2, and a pair of storage cylinders 22 are provided. A cleaning cylinder 23 is built into the storage cylinder 22, and a cover plate 24 is connected to the top of the cleaning cylinder 23; one of the cleaning cylinders 23 stores clean water, and the other is used to store waste water. By absorbing clean water, the dropper or syringe and other instruments used to transfer samples are cleaned, and the cleaned water is then poured into the other cleaning cylinder 23.

[0033] Working principle:

[0034] First, place the beverage sample to be tested into the sample tube 6, then take out the test paper from the test paper storage box 25, and then lay the test paper flat into the soaking tank 8 to soak the test paper in the beverage sample. After the test paper is fully colored, take out the test paper and judge whether it contains pigment based on the color.
