Description

Technical Field

[0001] The utility model relates to the technical field of sand and dust testing, in particular to a testing instrument for cold chain food. Background Art

[0002] In order to carry out quarantine work, ports often need to be equipped with epidemic prevention and control detection devices for cold chain foods. However, existing cold chain foods are generally packed in packaging bags. Sampling and testing of cold chain foods usually requires opening the packaging bags containing cold chain foods. After opening the packaging bags containing cold chain foods, the detection device samples and tests the inside of the cold chain foods. During the sampling and testing process, the cold chain foods in the packaging bags need to be completely thawed or holes need to be drilled before the cold chain foods can be taken for testing. Moreover, overall thawing will inevitably destroy the freshness of the cold chain foods. However, after the packaging bags are opened during the sampling process, the external environment will contaminate the sampled cold chain foods, or the sampled cold chain foods will contaminate the outside world.
