Description

Technical Field

[0001] The utility model relates to the field of crushing mechanisms, in particular to a crushing mechanism for food detection with a screening function. Background Art

[0002] Food safety detection is to detect harmful substances in food according to national standards, mainly the detection of some harmful and toxic indicators, such as heavy metals, aflatoxins, etc. The main purpose is to ensure the safety, quality and compliance of food.

[0003] However, the main process of existing food detection is to obtain samples from food, take out some food and analyze the samples using chemical, physical or microbiological methods, and then generate a report. In such a detection method, the sampling is relatively partial, and the detected data is not very comprehensive. At the same time, the taken-out food may be mixed with packaging materials or agglomerated food, which also has a certain impact on the detected data.

[0004] Therefore, aiming at the problems of uneven food sampling and the inability to handle the food mixed with packaging materials or agglomerated food in food samples, a crushing mechanism for food detection with a screening function can be designed. Content of the Utility Model
