Description

Technical Field

[0001] This utility model relates to the field of food safety testing equipment technology, specifically to a deep multi-point sampler for food testing. Background Art

[0002] Food safety testing involves detecting harmful substances in food according to national standards, primarily targeting harmful and toxic indicators such as heavy metals and aflatoxin. Food safety issues not only affect the lives and property of the general public but also constrain the economic development of the entire country. As food safety problems enter a period of frequent occurrence, the demand for food safety testing is constantly increasing, thus requiring relevant food testing equipment.

[0003] The prior art discloses a food sampling device with publication number CN217561048U, which includes a placement cylinder and a sampling component. The bottom of the placement cylinder is connected to a base plate, and the top of the placement cylinder is connected to a top plate. The sampling component includes a sampling cylinder and a pinch plate connected to the top of the sampling cylinder. A detachable liquid sampling head or solid sampling head is connected to the bottom of the sampling cylinder. A piston assembly for pumping liquid is installed inside the sampling cylinder. The top plate has an installation port that communicates with the inside of the placement cylinder. A capping assembly is installed on the installation port. The top of the outer wall of the sampling cylinder has an external thread, and the installation port has an internal thread that mates with the external thread. In this utility model, the sampling component and the placement cylinder are combined for convenient temporary placement or protection of the sample after sampling. The sampling component can sample liquids or solids and is suitable for sampling various foods.

[0004] When using the above-mentioned utility model, a single sampling is performed using a sampling tube in conjunction with a corresponding detachable liquid sampling head or solid sampling head. The sample is then injected into a storage tube for collection. However, sometimes it is necessary to sample multiple points at different depths of the same food. Using a sampling tube to sample one by one is not only cumbersome and inconvenient, reducing sampling efficiency, but also makes it difficult to ensure the accuracy of the gradient height difference in the depth direction, thus reducing its scope of application and making it generally impractical.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, this utility model provides a multi-point deep sampler for food testing, which has the following beneficial effects:

[0017] (1) This utility model is equipped with a sampling cylinder, a sampling plate, a liquid sampling head, and a solid sampling head. When sampling liquid food, the user can open the second sealing plug on the sampling head placement cavity and take out multiple liquid sampling heads of different lengths. Then, the user can remove the sampling cylinder from the storage hole. The sampling plate is fixedly installed at the bottom of the sampling cylinder, and the main extraction hole in the center of the sampling plate is connected to the inner cavity of the sampling cylinder. Several support extraction holes evenly installed on the bottom surface of the sampling plate are connected to the main extraction hole through the connecting hole.

This enables the food testing depth multi-point sampler to complete multi-point sampling in the depth direction of the sample at one time, which is beneficial to improve its sampling efficiency and ensures the accuracy of sampling, making it more practical.

[0031] In one embodiment, the inner walls of the liquid sampling head 3 and the solid sampling head 7 are provided with threads that mate with the mounting threaded head 16, which serves to sample liquid or solid food and has a wide range of applications.

[0032] In one embodiment, the top of the inner wall of the receiving hole 6 is provided with an internal thread 21, and the top of the outer wall of the sampling cylinder 8 is provided with an external thread 15.

[0037] Working principle: This utility model is equipped with a sampling cylinder 8, a sampling plate 10, a liquid sampling head 3, and a solid sampling head 7. When sampling liquid food, the user can open the second sealing plug 14 on the sampling head placement cavity 4 to take out multiple liquid sampling heads 3 of different lengths. Then, the user can remove the sampling cylinder 8 from the storage hole 6. The sampling plate 10 is fixedly installed at the bottom of the sampling cylinder 8, and the main extraction hole 18 in the center of the sampling plate 10 is connected to the inner cavity of the sampling cylinder 8. Several support extraction holes 20 evenly installed on the bottom surface of the sampling plate 10 are connected to the main extraction hole 18 through the connecting hole 19. The support extraction holes 20 are located in the center of the inner cavity of the mounting thread head 16. When in use, the user can unscrew the sealing plug on the mounting thread head 16. Connect the cap 11, then screw multiple liquid sampling heads 3 of different lengths onto the mounting thread head 16. Finally, insert the multiple liquid sampling heads 3 into the liquid food along the depth direction. At this time, the user pulls the piston rod 5 to move the piston head 17 along the inner cavity of the sampling cylinder 8, so that multiple points in the depth of the liquid food can be sampled simultaneously. The liquid food samples at each point are drawn into the inner cavity of the liquid sampling head 3. After sampling is completed, the user opens the first sealing plug 13 on the sample storage cavity 2, inserts the multiple sampled liquid sampling heads 3 into the corresponding sample storage cavity 2, and then presses the piston rod 5 to push the piston head 17 downward, so that several liquid food samples can be injected into the sample storage cavity 2 for storage. The depth multi-point sampler for food testing can complete multi-point sampling of samples in the depth direction at one time, which is beneficial to improve sampling efficiency and ensures sampling accuracy, making it more practical. When sampling fixed food, the solid sampling head 7 can be screwed onto the installation thread head 16. At this time, the sampling cylinder 8 is used as a handle to facilitate the scooping and sampling of solid food. The collected solid samples can also be placed in the sample storage tank, and the corresponding information can be marked on the label groove 22 on the first sealing plug 13 to complete the food testing sampling. In addition, this utility model is equipped with a storage hole 6, a sampling cylinder 8, and a sampling head placement cavity 4. When not in use, the user can wash and disinfect the liquid sampling head 3 and the solid sampling head 7 and place them in the sampling head placement cavity 4. A second sealing plug 14 is inserted into the sampling head placement cavity 4, and the corresponding sampling head information is marked in the label groove 22 of the second sealing plug 14 for future use. The sampling tube 8 can be inserted into the storage hole 6 in the center of the device body 1. The inner wall of the storage hole 6 is provided with an internal thread 21, and the top of the outer wall of the sampling tube 8 is provided with an external thread 15. The sampling tube 8 can be fixedly stored on the device body 1 by screwing the external thread 15 and the internal thread 21 together. The bottom surface of the base plate 9 is fixedly installed with a support tube 12, which can protect the sampling plate 10 and support the device body 1 and the base plate 9. This makes it easier to place and store the food testing depth multi-point sampler when not in use, and makes it more practical.
