Description

Technical Field

[0002] Food additives are synthetic or natural substances added to food to improve its color, aroma, and flavor, as well as for preservation and processing needs. With the improvement of living standards, people are increasingly concerned about their quality of life, and food safety is a particular concern. The issue of food additives is also a topic of concern, making the detection of food additives in food particularly important.

[0003] Food quality testers that use spectrophotometry can quickly detect the content of multiple parameters of food additives such as sulfur dioxide, nitrite, and nitrate in food by adding the extracted sample to a cuvette and inserting it into the cuvette slot of the tester. The cuvette needs to be cleaned after use to avoid corrosion or contamination caused by residual test samples. The cuvette needs to be dried after cleaning. Generally, the cuvette is placed on a dedicated cuvette rack and allowed to dry naturally. However, natural drying takes a long time, and when the number of cuvettes is small, it cannot meet the needs of multi-sample testing. In addition, natural drying can easily cause dust and impurities to enter the cuvette, causing contamination of the cuvette and affecting the detection accuracy. Utility Model Content

DETAILED DESCRIPTION

[0019] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] See also Figures 1 to 4 The present invention provides a food additive detection device in accordance with an embodiment of the present invention, including a detector body 1. The detector body 1 is a food quality detector using spectrophotometry in the prior art. The detector body 1 is provided with a cuvette slot 2, and may also be provided with a display screen, a micro printer, and a power switch. The above are all prior art and will not be described in detail.

[0021] The key point of this embodiment is that a storage box 3 is provided on one side of the detector body 1, and a partition 4 is fixed in the storage box 3. The partition 4 divides the inner cavity of the storage box 3 into a drying chamber 5 located on the upper layer and an air inlet chamber 6 located on the lower layer. The drying chamber 5 is provided with a plurality of drying slots 8 for inserting the cuvette 7 in an inverted manner. The top of the drying slot 8 is an open structure. The inner cavity of the drying slot 8 is adapted to the shape of the cuvette 7. The top of the drying slot 8 is connected to the inner wall of the top of the storage box 3. The top of the storage box 3 is provided with an opening corresponding to and connected to the drying slot 8. 9. The top end of the drying tank 8 is connected to the outside world through an opening 9. A first air inlet 10 and a first exhaust 11 are formed at the bottom of the drying tank 8. A second air inlet 12 is formed on the partition 4, corresponding one-to-one with the first air inlet 10. The first air inlet 10 is connected to the second air inlet 12 via an air inlet pipe 13. A second exhaust 14 is formed on a side wall of the storage box 3, which is connected to the drying chamber 5. A third air inlet 15 is formed on a side wall of the storage box 3, which is connected to the air inlet chamber 6. An air intake fan 16 is installed in the air inlet chamber 6. The third air inlet 15, the air inlet chamber 6, the second air inlet 12, the air inlet pipe 13, the first air inlet 10, the first exhaust 11, the drying chamber 5, and the second exhaust 14 are connected in sequence. The function of the air intake fan 16 is to draw air into the air intake cavity and the second air intake port 12, so that the outside air enters the air intake cavity 6 from the third air intake port 15, and enters the second air intake port 12, the air intake pipe 13, the first air intake port 10, the first exhaust port 11, the drying cavity 5 in turn, and is finally discharged from the second exhaust port 14.

[0022] To facilitate sealing of opening 9 and prevent air from entering drying tank 8 from being exhausted through opening 9, a sealing cover 17 is provided at the top of storage box 3, corresponding to opening 9. Sealing cover 17 is hingedly connected to storage box 3 via spring hinge 18. In its natural state, the elastic force of spring hinge 18 stabilizes sealing cover 17 within storage box 3, sealing opening 9. This prevents air from entering drying tank 8 from being exhausted through opening 9 when no color dish 7 is placed in drying tank 8, and also prevents foreign matter from entering drying tank 8 through opening 9.

[0023] To prevent impurities in the outside air from entering the air inlet chamber 6, the second air inlet 12, the air inlet pipe 13, the drying tank 8, and the cuvette 7 through the third air inlet 15, a first filter 19 is installed at the third air inlet 15. The first filter 19 can filter impurities in the outside air.

[0024] In order to facilitate the intake fan 16 to introduce external air into the intake cavity through the third air inlet 15 , a guide frame 20 is arranged in the intake cavity 6 and fixed outside the second air inlet 12 , and the intake fan 16 is installed in the guide frame 20 .

[0025] In order to further prevent impurities in the external air from entering the cuvette 7 , a second filter 21 is installed at the second air inlet 12 .

[0026] In order to prevent impurities in the external air from entering the exhaust cavity and the cuvette 7 through the second exhaust port 14 , a third filter screen 22 is installed at the second exhaust port 14 .

[0027] To improve the fluidity of air in the cuvette 7, a vertical plate 23 is fixed inside the drying tank 8. The lower end of the vertical plate 23 is fixedly connected to the inner wall of the bottom end of the drying tank 8. The first air inlet 10 and the first exhaust port 11 are located on either side of the vertical plate 23. When the cuvette 7 is inserted into the drying tank 8, the first air inlet 10 and the first exhaust port 11 are both connected to the inner cavity of the cuvette 7. There is a gap between the top of the vertical plate 23 and the inner wall of the top of the cuvette 7 for air to pass through. When the cuvette 7 is inserted into the drying tank 8, the vertical plate 23 is spaced apart from the side wall of the cuvette 7. The vertical plate 23 forms an n-shaped guide channel inside the cuvette 7, increasing the distance of air flowing in the cuvette 7 and ensuring that all positions inside the cuvette 7 are in uniform contact with the air, avoiding dead corners where air circulation is poor.

[0028] The working principle of this embodiment is as follows:

[0029] After the cuvette 7 is cleaned and drained, it is inserted upside down into the drying tank 8 through the opening 9. The bottom end of the cuvette 7 abuts against the inner wall of the bottom end of the drying tank 8, and the top end of the cuvette 7 extends out of the drying tank 8 and is located above the storage box 3, which can be easily pulled out. Before the cuvette 7 is inserted into the drying tank 8, it is necessary to operate the closing cover 17 to expose the opening 9. After the cuvette 7 is inserted into the drying tank 8, the closing cover 17 is released. Under the elastic restoring force of the spring hinge 18, the closing cover 17 automatically resets and closes the opening 9, covering the portion of the cuvette 7 extending out of the drying tank 8.

[0030] The air intake fan 16 draws air into the air intake cavity, so that the outside air enters the air intake cavity 6, the second air intake 12, the air intake pipe 13, the first air intake 10, the first exhaust port 11, and the drying cavity 5 in sequence from the third air intake 15, and is finally discharged from the second exhaust port 14. The air enters the inner cavity of the cuvette 7 from the first air intake 10, and is then discharged from the first exhaust port 11, thereby improving the air fluidity inside the cuvette 7 and improving the drying efficiency.

[0031] The first filter 19 , the second filter 21 and the third filter 22 can prevent impurities in the external air from entering the storage box 3 , ensure that the cuvette 7 is in contact with clean air, and prevent the cuvette 7 from being contaminated during the drying process.
