Description

Technical Field

[0001] The utility model relates to the field of food detection, in particular to a liquid substance sedimentation prevention sampling device for food detection. Background Art

[0002] Food safety testing is to detect harmful substances in food according to national indicators, mainly some harmful and toxic indicators, such as heavy metals, aflatoxin, etc., and some liquid foods mostly use sampling equipment when conducting testing operations. The liquid food is first sampled for subsequent testing operations.

[0003] Liquid food is fluid, so when liquid food is left for a long time, other substances in the liquid food are likely to precipitate. In this way, after sampling the liquid food, the sample taken out may contain only a small amount of precipitated substances, which may lead to inaccurate detection results of the liquid food after sampling. Even if the internal substances of the liquid food have not been precipitated during sampling, the sampled liquid food needs to be transferred to a detection mechanism after sampling. In this process, the liquid food after sampling is likely to precipitate, thereby affecting the subsequent detection structure. Utility Model Content
