Description

Technical Field

[0001] This utility model relates to the field of grain and oil testing technology, and in particular to a portable grain and oil testing device. Background Technology

[0002] Grain and oil testing refers to the process of systematically analyzing the quality, safety, and nutritional components of grains and edible oils using physical, chemical, or biological technologies. This ensures that grain and oil products meet national food safety standards, protect consumer health, and maintain market order. In the process of testing edible oils, it is necessary to test their quality indicators to ensure their safety.

[0003] Existing methods for testing edible oils mostly involve using sampling devices to collect and store samples of the oil to be tested, and then transporting the samples to a laboratory for accurate measurement. However, the testing equipment is quite large and complex, making it inconvenient to carry out on-site testing by testing personnel in daily use.

[0004] Therefore, given that the aforementioned testing equipment is bulky and complex in structure, making it inconvenient to carry and unsuitable for on-site testing by testing personnel, a portable testing device can be developed. This device allows for easy carrying and on-the-spot testing, while the use of test strips enables rapid on-site testing of edible oils. Utility Model Content

The lamp 205 is located directly below the light-transmitting groove 203. A control switch 206 is provided on the top surface of the support frame 2. The control switch 206 is electrically connected to the lamp holder 204. The lamp holder 204 provides support for the lamp 205. The control switch 206 controls the lamp 205 to turn on and off. When testing grains and oils in a relatively dim environment, the control switch 206 controls the lamp 205 to turn on, and the light-transmitting groove 203 provides supplemental light to the test card 209, ensuring uniform brightness in the color display area, avoiding shadows caused by external light that interfere with the observation results, and reducing the influence of ambient color temperature.

[0028] A testing platform 207 is fixedly connected to the center of the top surface of the support frame 2. A limiting slot 208 is opened on the top surface of the testing platform 207. The limiting slot 208 is connected to the light transmission slot 203. A testing card 209 is slidably connected to the inner wall of the limiting slot 208. The removed testing card 209 is inserted into the testing platform 207 through the limiting slot 208, so that the test groove on the top surface of the testing card 209 is directly above the light transmission slot 203. The oil sample to be tested and the test reagent are dripped into the test groove on the top surface of the testing card 209.

After the oil sample develops color, it is compared with the standard color of the colorimetric card to determine whether the grain and oil have deteriorated.

[0029] The top surface of the protective base 3 is provided with reagent storage slots 301 at equal intervals. Clamping springs 302 are fixedly connected to the side of the protective base 3. The clamping springs 302 are symmetrically and alternately distributed on the protective base 3. The ends of the clamping springs 302 are fixedly connected to arc-shaped clamps 303. The arc-shaped clamps 303 are set on the top surface of the protective base 3 and are symmetrically distributed on the protective base 3. The container containing the reaction reagent is placed in the reagent storage slot 301 for easy carrying and use. The elastic force of the clamping springs 302 pushes the arc-shaped clamps 303 to clamp and fix the mouth of the reagent bottle, so as to keep the reagent stable during carrying.

The support clamp 405 is slidably connected to the inner wall of the locking frame 403. The empty locking frame 403 is removed from the limiting seat 4. The support springs 404 are compressed by pressing the support clamp 405. The locking frame 403 is then opened through the slot on the side. Stacked test cards 209 are placed into the card holder 403 for storage. The support spring 404 pushes the support clamp 405 to limit and hold the test cards 209. The card holder 403 is then inserted into the card slot 401 and is attracted and fixed by the magnetic base 402 to maintain the stability of the card holder 403.

Under the action of the support spring 404, the support clamp 405 pushes the remaining test cards 209 upward to facilitate the next extraction and use, thus realizing the automatic feeding of test cards 209.

[0031] Working principle: According to Figure 1 , Figure 3 and Figure 6 As shown, during operation, the support spring 404 is compressed by pressing the support clamp 405, and the stacked test cards 209 are placed into the card holder 403 through the slot on the side of the card holder 403 for storage.

The card holder 403 is then inserted into the card slot 401, and the card holder 403 is attracted and fixed by the magnetic base 402 to keep the card holder 403 stable, thus completing the replenishment of the test cards 209.

[0032] according to Figure 1 , Figure 3 and Figure 5As shown, the container holding the reaction reagent is placed in the reagent storage slot 301 for easy carrying and use. The elastic force of the clamping spring 302 pushes the arc-shaped clamp 303 to clamp and fix the mouth of the reagent bottle, so as to keep the reagent stable during carrying.

[0033] according to Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, when testing grains and oils in a relatively dim environment, the lighting lamp 205 is turned on by the control switch 206, and the light-transmitting groove 203 provides supplemental light for the test card 209 to ensure uniform brightness in the color display area. By sliding outward to pull out the top test card 209, the remaining test cards 209 are pushed upward by the support clamp 405 under the elastic force of the support spring 404, making it easier to pull out and use next time, thus realizing the automatic feeding of the test cards 209.

[0034] according to Figure 1 , Figure 3 and Figure 4 As shown, the removed test card 209 is inserted into the test platform 207 through the limiting card slot 208, so that the test groove on the top surface of the test card 209 is directly above the light transmission slot 203. The oil sample to be tested and the test reagent are dripped into the test groove on the top surface of the test card 209. The degree of deterioration of the oil is determined by the oxidation-reduction reaction of the oil sample and the reagent. After the oil sample develops color, it is compared with the standard color of the colorimetric card to determine whether the grain and oil have deteriorated.
