Description

Technical Field

[0001] This utility model relates to the field of food processing safety testing technology, specifically a food safety testing device for walnut milk production with a hybrid structure. Background Technology

[0002] Walnut milk is a plant-based protein beverage made primarily from walnut kernels and purified water using modern processing techniques and scientific formulation. Food safety is paramount during its production. Currently, testing of walnut milk mainly focuses on laboratory sampling before the finished product leaves the factory. The testing items include microbiological indicators (such as total bacterial count and E. coli), physicochemical indicators (such as peroxide value and acid value), and whether there are excessive additives.

[0003] In the production of plant protein beverages such as walnut milk, online refractometers are key equipment for sugar content detection. However, these emulsions have poor stability and are prone to fat floating and solid sedimentation, which can cause the test samples to lose their representativeness and the measurement results to be biased. Existing improvement methods, such as manual stirring, will interrupt the detection process and are prone to sample contamination and spillage. Installing large-scale online homogenizing equipment is costly and complex to maintain.

[0004] Therefore, there is an urgent need to develop a detection device that can mix samples during the detection process, re-homogenize the samples during detection, ensure the accuracy and efficiency of soluble solids content, and provide reliable quality control for the production process. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a food safety testing device for walnut milk production with a mixing structure, which has the advantage of being able to stir the sample during testing, thus solving the problems mentioned in the background technology.

By setting a rotating shaft and a stirring rod on the cover plate, when the rotating shaft is rotated, the rotating shaft can drive the stirring rod to rotate through the driving gear and the driven gear. Since the diameter of the driving gear is larger than that of the driven gear, the rotation speed of the stirring rod can be increased. The stirring rod can stir the sample inside the sample cell through the stirring blades, avoiding the floating of fat and the sedimentation of solids, reducing detection deviation, and can re-homogenize the sample during detection, ensuring the accuracy and efficiency of soluble solids content. The structure is simple and the maintenance cost is low.

[0015] 2. By closing the cover, the limiting component can quickly limit its position, preventing it from loosening during stirring. The sealing gasket increases the sealing between the cover and the sample tank, making it less likely to contaminate the sample and preventing sample spillage. The quick-release component allows for quick removal of the cover, facilitating cleaning. Attached Figure Description

Since the diameter of the drive gear 16 is larger than the diameter of the driven gear 15, the rotation speed of the stirring rod 13 can be increased. The stirring rod 13 can stir the sample inside the sample tank 3 through the stirring blade 14, avoiding the floating of fat and the sedimentation of solids, reducing the detection deviation, and making the sample homogenize again during the detection, ensuring the accuracy and efficiency of the soluble solids content. In this embodiment, preferably, the quick-release assembly 7 includes a mounting plate 701. A mounting groove 702 is formed on one side of the mounting plate 701. A spring 703 is provided inside the mounting groove 702. Both ends of the spring 703 are engaged with spring posts. A slide rod 704 is fixedly provided at one end of each spring post. The slide rod 704 is slidably connected to the interior of the mounting groove 702. An insertion rod 705 is fixedly provided at the middle of one end of the slide rod 704.

By releasing the push plate 909, the second spring 903 can push the locking block 905 into the card slot 10 through the slide plate 904, thereby quickly locking the cover plate 6. In this embodiment, preferably, the bottom end of the cover plate 6 has a groove 11, and the sealing gasket 12 is engaged with the inside of the groove 11. The sealing gasket 12 is coaxial with the sample groove 3. The top end of the cover plate 6 has a protective cover 21 that provides protection for the driven gear 15 and the driving gear 16. The bottom of both sides of the protective cover 21 is fixedly provided with mounting strips 22. The bottom end of the mounting strips 22 is fixedly connected to the top end of the cover plate 6 by screws.

The protective cover 21 can provide protection for the driven gear 15 and the driving gear 16, preventing them from being exposed to the outside. The locking post 19 and the groove 20 facilitate the installation of the knob 18. The rotating shaft 17 can be rotated by the knob 18.

[0020] In use, first pour the walnut milk sample into the sample slot 3, then push the slide plate 904 through the push plate 909 of the limiting component 9 to compress the second spring 903. The slide plate 904 can drive the locking block 905 to move. Then close the cover plate 6. After the cover plate 6 is closed, release the push plate 909. The second spring 903 can push the locking block 905 into the slot 10 through the slide plate 904, which can quickly lock the cover plate 6. The sealing gasket 12 at the bottom of the cover plate 6 can increase the sealing between the cover plate 6 and the sample slot 3, making it less likely to contaminate the sample and preventing the sample from spilling. After the cover plate 6 is fixed, the rotating shaft 17 is rotated by the knob 18. The rotating shaft 17 can drive the stirring rod 13 to rotate through the driving gear 16 and the driven gear 15. Since the diameter of the driving gear 16 is larger than the diameter of the driven gear 15, the rotation speed of the stirring rod 13 can be increased. The stirring rod 13 can stir the sample inside the sample tank 3 through the stirring blade 14, avoiding the floating of fat and the sedimentation of solids, and reducing the detection deviation. When it is necessary to disassemble and clean the cover plate 6 and the stirring rod 13, push the two push rods 706 of the quick-release assembly 7 in opposite directions to compress the spring 703 by the slide rod 704, and quickly pull the insert rod 705 out of the slot 8 to remove the cover plate 6 and clean it. After cleaning, the spring 703 can be compressed again by the push rod 706 to quickly install it.
