Description

Technical Field

[0001] The utility model relates to the technical field of fruit preservative determination, in particular to a detection device for fruit preservatives. Background Technique

[0002] The main function of fruit preservatives is to extend the storage period of fruits, reduce post-harvest losses of agricultural products, ensure the long-distance transportation and off-peak marketing of fruits, and maintain the quality and appearance of fruits, thereby enhancing the value of fruits. The application methods of fruit preservatives mainly include smearing method, soaking method and wrapping method. Among them, ethoxyquin can be used as a preservative. Ethoxyquin is an effective antioxidant fruit preservative and is commonly used for the preservation of fruits such as pears. It belongs to antioxidants and can prevent fruits from oxidizing and deteriorating, maintaining their freshness and nutritional value. When using ethoxyquin as a preservative, if the human body ingests excessive ethoxyquin, it will damage human tissues and organs. When it is used as a preservative, it needs to be detected. When determining the content of ethoxyquin in the preservative, 500 g of the edible part of the representative sample is taken, 10 g of ascorbic acid is added, and then after sample extraction, the sample test solutions after extracting multiple samples are respectively injected into a liquid chromatograph to measure the corresponding peak areas, and the concentration of ethoxyquin in the standard series working solutions is used.

[0003] In the prior art, when adding ascorbic acid, it is necessary to mix it with the sample to form a slurry to facilitate the subsequent addition of various reagents for extraction. In this process, the existing tissue homogenizer is mainly used for mixing. Since the main principle of the tissue homogenizer is similar to that of the existing crusher, when placed in a large-volume container, it is necessary to pour it into multiple sample tubes in sequence later. In this process, it is not easy to quantitatively pour the large-volume container, resulting in the need to re-formulate when adding various reagents later, increasing the operation steps and affecting the determination efficiency. Therefore, we propose a detection device for fruit preservatives to solve the above problems. Content of the Utility Model

[0021] As Figures 1-4 shown, it relates to a detection device for a fruit preservative, including a machine base 1. A tissue homogenizer body 2 is fixedly connected to the top of the machine base 1. A motor is installed inside the tissue homogenizer body 2, and the motor drives the crushing cutter to rotate to crush the tissue. A crushing cutter is installed at the bottom of the tissue homogenizer body 2.

[0022] A T-shaped seat 3 is fixedly connected to the top of the machine base 1. A container 5 is placed on the top of the T-shaped seat 3. A plurality of rubber columns 4 are fixedly connected to the top of the T-shaped seat 3. A plurality of round holes are evenly formed in the bottom of the container 5. The inner walls of the plurality of round holes are respectively slidably connected to the outer walls of the plurality of rubber columns 4. The rubber columns 4 cooperate with the round holes, which is beneficial to the stability of the container 5 during use.

[0023] A supporting seat 6 is rotatably sleeved on the outer wall of the T-shaped seat 3. A plurality of rubber sleeves 7 are fixedly connected to the outer wall of the supporting seat 6. A plurality of sample tubes 8 are placed inside the inner walls of the plurality of rubber sleeves 7. The sample tubes 8 are prevented from tipping over through the rubber sleeves 7 to ensure their vertical state. After the supporting seat 6 rotates, it drives the plurality of sample tubes 8 to rotate, so as to conveniently feed the samples into the sample tubes 8 in sequence.

[0024] Two suction pipes 9 are fixedly connected to the outer wall of the container 5. Scale lines are provided on the outer wall of the suction pipe 9, so that the slurry enters the sample tube 8 quantitatively through the scale lines. A partition 10 is fixedly connected to the inside of the suction pipe 9. The outer wall of the partition 10 is fixedly communicated with a slurry inlet pipe 11. One end of the slurry inlet pipe 11 is fixedly communicated with the outer wall of the container 5.

[0025] A suction mechanism is provided inside the suction pipe 9. The suction mechanism includes a piston 14. A discharge pipe 12 is fixedly communicated with the outer wall of the suction pipe 9. Check valves 13 are fixedly installed on the outer walls of the slurry inlet pipe 11 and the discharge pipe 12. The check valves 13 prevent the slurry from flowing back.

[0026] The inner wall of the suction pipe 9 is slidably connected to the outer wall of the piston 14. A straight rod 15 is fixedly connected to the outer wall of the piston 14. A sliding hole is formed in the outer wall of the suction pipe 9. The inner wall of the sliding hole is slidably connected to the outer wall of the straight rod 15. One end of the straight rod 15 is fixedly connected to an I-shaped push-pull block 16. By moving the I-shaped push-pull block 16, the suction pipe 9 sucks the slurry in the container 5.

[0027] Working principle: When in use, take a certain amount of representative edible part of the sample, add ascorbic acid and place it in container 5. Place the crushing tool on the tissue homogenizer body 2 into container 5. The internal motor of the tissue homogenizer body 2 drives the crushing tool to rotate, crush the sample and mix it with ascorbic acid. During the mixing process, place multiple sample tubes 8 into multiple rubber sleeves 7 in advance to facilitate sampling. After mixing, pull the I-shaped push-pull block 16 to drive the straight rod 15 to move outwards. The outward movement of the straight rod 15 drives the piston 14 to move outwards. The outward movement of the piston 14 creates a negative pressure environment in the suction pipe 9, and sucks the bottom slurry of container 5 into the suction pipe 9 through the slurry inlet pipe 11. Then move the I-shaped push-pull block 16 inwards, and the piston 14 pushes the slurry in the suction pipe 9. The check valve 13 on the slurry inlet pipe 11 blocks the slurry from re-entering container 5, and discharges it downward through the slurry discharge pipe 12. The mouths of the pre-placed sample tubes 8 are located below the slurry discharge pipe 12. When discharging the slurry, by observing the scale line on the suction pipe 9, the operation can be carried out according to the required amount of the sample. For the sample amounts of other sample tubes 8 subsequently, take the amount of the first sample as the standard. Rotate the supporting seat 6 to place the sample tubes 8 successively below the slurry discharge pipe 12.
