The testing is conducted using methods such as chromatography, spectral analysis, and biotechnology. Sampling is required before testing.

[0003] Food inspection refers to the study and evaluation of food composition and quality. Based on fundamental theories of physics, chemistry, and biochemistry, and various techniques, it inspects the quality of food raw materials, auxiliary materials, semi-finished products, finished products, and by-products according to established technical standards, such as international and national food hygiene / safety standards, to ensure product quality compliance. Food inspection includes sensory testing, detection of nutrients, additives, and harmful substances. In industries closely related to people's daily lives, such as food and pharmaceutical companies specializing in refined products, quality inspection is crucial, and quality inspectors often need to take samples to test for quality issues.

[0004] The aforementioned device has the following drawbacks: because liquid foods have the property of settling and mixing, it is usually necessary to sample and test the surface, bottom, and other parts of the liquid food in multiple batches to obtain more comprehensive test data. However, the method of sampling in multiple batches is time-consuming and cumbersome, which adversely affects the efficiency of food testing. Furthermore, multiple sampling may also prolong the food retention time, leading to changes in food quality and affecting the test data. Therefore, a sampling device for food testing is proposed to solve the above problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-3This utility model provides an embodiment of a sampling device for food testing, comprising a sampling frame 1, a sampling mechanism 2 and an auxiliary mechanism 3 mounted on the sampling frame 1. The sampling mechanism 2 includes an annular opening 21, which is located on the inner walls of the top and bottom sides of the sampling frame 1. By opening the annular opening 21 on the inner walls of the top and bottom sides of the sampling frame 1, the vertical installation and telescopic adjustment of the sampling cylinder 25 can be achieved, while limiting the installation position of the sampling cylinder 25 to avoid displacement affecting sampling accuracy. A piston plate 22 is slidably connected to the top inner wall of the annular opening 21. The sliding cooperation between the piston plate 22 and the top inner wall of the annular opening 21 can change the internal air pressure of the sampling cylinder 25 through lifting and lowering movements, providing power for the suction needle 26 to draw samples. A support rod 23 is fixedly connected to the top outer wall of the piston plate 22, and a handle 24 is fixedly connected to the top outer wall of the support rod 23. A sampling cylinder 25 is threadedly connected to the inner wall of the inner ring of the ring 21, and a suction needle 26 is fixedly connected to the bottom outer wall of the sampling cylinder 25. The suction needle 26 adopts a sharp structure design, which makes it easy to insert into liquid food and accurately obtain samples at different depths. At the same time, the fixed connection with the sampling cylinder 25 ensures that there is no risk of falling off during the sampling process and ensures the continuity of sample collection. A scale 27 is opened on the front outer wall of the sampling cylinder 25. The scale 27 can intuitively display the extension length of the sampling cylinder 25, helping the operator to quickly and accurately adjust to the required sampling depth, avoiding sample deviation caused by inaccurate depth control, and improving sampling accuracy.

[0018] Reference Figures 2-4 A silicone sleeve is fixedly connected to the outer side wall of the handle 24. The silicone sleeve can increase the friction between the hand and the handle 24, prevent slippage during pulling, and the soft silicone sleeve can reduce hand fatigue caused by long-term operation and improve grip comfort. The piston plate 22 contacts the top outer wall of the sampling cylinder 25. A sealing ring is attached to the top outer wall of the sampling cylinder 25. The sealing ring is slidably connected to the inner side wall of the ring 21. A display coating is fixedly connected to the front outer wall of the scale 27. The display coating can improve the clarity of the scale of the scale 27, and the value can be read accurately even in low light environment, avoiding adjustment errors caused by blurry scale.

[0019] Reference Figures 3-4The auxiliary mechanism 3 includes a frosted plate 31, which is fixedly connected to the front and rear outer walls of the sampling frame 1. The frosted plate 31 is an anti-slip component of the auxiliary mechanism 3, used to improve the stability of the sampling frame 1 when the operator holds it. The inner right wall of the sampling frame 1 has an opening 32, and an arc-shaped buckle 33 is fitted on the inner right wall of the opening 32. The arc-shaped buckle 33 is the core component for carrying the equipment, used to connect the rope and other carrying components. The bottom inner wall of the arc-shaped buckle 33 has an opening 34, which is elastically designed to facilitate quick insertion or removal of the rope component. The arc-shaped buckle 33 is four millimeters wide, and a frosted sleeve is fixedly connected to the outer side wall of the arc-shaped buckle 33. The frosted sleeve can increase the friction between the arc-shaped buckle 33 and the rope, preventing the rope from slipping and falling off during carrying, and improving the safety of carrying the equipment.

[0020] Working principle: Based on the required depth for liquid food detection, the scale 27 is observed and the sampling tube 25 is rotated to extend the required length from the bottom of the ring 21. After the two sampling tubes 25 are adjusted to different lengths, two suction needles 26 can be inserted at once. Then, the handle 24 is pulled to move the support rod 23. The movement of the support rod 23 drives the piston plate 22 upward, causing the suction needles 26 to generate suction and draw the food into the sampling tube 25. This facilitates the simultaneous extraction of liquid food at different depths, improving sampling efficiency and avoiding the problem of long sampling time due to complex operations. At the same time, when carried by personnel, the sampling frame 1 can be easily carried by fitting the opening 34 on the arc-shaped buckle 33 into different rope components, eliminating the need for continuous hand operation.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
