Description

Technical Field

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

[0002] Liquid food samples are generally collected and stored through liquid sampling tubes before being sent to a testing device for testing.

[0003] During transportation, liquid food easily flows out of the end of the existing sampling tube, which requires time-consuming and laborious cleaning by the staff. After the staff takes out the liquid in the sampling tube, there will be liquid residue in the sampling tube. The staff can only clean the sampling tubes one by one and cannot clean multiple sampling tubes at a time. In addition, most of the existing sampling tube placement racks can only fix sampling tubes of a specified size. When encountering sampling tubes of different sizes, they cannot be limited, resulting in low practicality. Utility Model Content
