Description

Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a food detection puncture sampling tube. Background Art

[0002] Food inspection is based on some basic theories and various technologies of physics, chemistry and biochemistry, and in accordance with established technical standards, such as international and national food hygiene / safety standards, to inspect the quality of food raw materials, auxiliary materials, semi-finished products, finished products and by-products to ensure product quality.

[0003] The puncture sampling tube is a tool specially used for collecting samples in food testing, and is particularly suitable for sampling solid or semi-solid foods.

[0004] For powdered foods like salt and seasoning powder, the sampling process is more troublesome. Since these foods are piled up in storage tanks and exert sufficient pressure on each other, only surface samples can be easily taken out during sampling. It is more difficult to take out samples at the bottom of the storage tank, resulting in one-sided and inaccurate test results.

[0005] The existing patent document with authorization announcement number CN 221959780 U discloses a food inspection puncture sampling tube, comprising a tube body, two handles fixedly connected to the tube body, and a sampling structure provided on the tube body, wherein the sampling structure mainly comprises two slide grooves.
