Description
Technical Field
[0001] This utility model relates to the field of food testing technology, specifically a sampling device for testing walnut milk with a protective structure. Background Technology
[0002] Walnut milk is a plant-based protein beverage made primarily from walnut kernels through grinding, emulsification, and other processes. It is rich in nutrients and widely popular. To ensure the safety and quality of the product and to meet national standards, as well as to prevent issues such as microbial contamination, rancidity of oils, or excessive additives, regular testing and sampling are necessary. By analyzing the physicochemical and microbiological indicators of the samples, the overall product quality can be monitored and risks assessed.
[0003] In the production and quality inspection of liquid foods such as walnut milk, regular sampling for microbiological and physicochemical testing is a crucial step in ensuring product quality and safety. Currently, commonly used sampling methods often employ simple long-handled spoons or disposable syringes. These methods have significant drawbacks: First, the sampling process exposes the sample to the air, easily introducing environmental contaminants such as microorganisms and dust, leading to sample distortion and affecting the accuracy of test results. Second, it is difficult to accurately sample deep or specific depth samples. Third, it easily leads to sample spillage.
[0004] Therefore, there is an urgent need for a specialized device that can achieve sterility and prevent spillage. Utility Model Content

An elastic support component 16 providing elastic support to the plug 20 is mounted at the bottom end of the sliding plate 13. The sampling cylinder 1... The sampling tube 14 is installed at the end, which can accurately sample deep samples or samples at a specific depth. The bottom end of the sampling tube 14 can be sealed by the plug 20, which avoids exposure to air during storage and sampling, and prevents the introduction of microorganisms, dust and other pollutants in the environment, which would cause sample distortion. By immersing the sampling tube 14 in walnut milk, the elastic support component 16 can be pushed by the slide plate 13 to make the plug 20 leave the sampling tube 14. The sealing plug 2 can then be pulled by the upright rod 5 to extract the walnut milk sample. After sampling, the slide plate 13 is released, and the elastic support component 16 can push the plug 20 to seal the bottom end of the sampling tube 14, preventing the sample from spilling through the sampling tube 14. In this embodiment, preferably, the guide limiting component 9 includes a crossbar 901. Both sides of the bottom end of the crossbar 901 are fixedly connected to both sides of the top end of the top plate 12 by screws.

[0020] In use, first, push the slider 903 of the guide limiting component 9 horizontally to push the limiting block 906 into the limiting groove 909 to ensure the sliding ability of the upright 5. Then, immerse the bottom end of the sampling tube 14 into the walnut milk. The sampling tube 14 is designed to accurately sample deep samples or samples at a specific depth. Then, push the slide plate 13 to compress the spring 1604 of the elastic support component 16, which will push the bracket 1603 and the connecting rod 1602 down, so that the plug 20 is separated from the sampling tube 14.

The spring 1604 can push the slide plate 13 back to its original position, which can push the plug 20 back to the bottom of the sampling tube 14 to seal the bottom of the sampling tube 14 and prevent the walnut milk from spilling. Then, push the second limiting block 906 out of the second limiting groove 909 and push the first limiting block 905 into the corresponding first limiting groove 7. The first limiting block 905 can lock the upright 5 and prevent the upright 5 from sliding under force, causing the sealing plug 2 to squeeze out the sample, which is safe and reliable. By loosening handle 10 and removing crossbar 901, the upright 5 and sealing plug 2 can be removed from the sampling cylinder 1. By loosening nut 1607, the bracket 1603 and spring 1604 can be disassembled, making it convenient to replace parts if damaged.
