Description

Technical Field

[0001] The utility model relates to the technical field of crushing devices, in particular to a sample crushing device for food safety testing. Background Art

[0002] Food safety means that food is non-toxic and harmless, meets the necessary nutritional requirements, and does not cause any acute, subacute or chronic harm to human health. Food safety is a public health issue that affects human health by toxic and harmful substances in food. Food safety is also an interdisciplinary field that specifically explores how to ensure food hygiene and food safety during food processing, storage, and sales, reduce disease risks, and prevent food poisoning. Therefore, food safety is very important.

[0003] After searching, it was found that the application number is CN202321464172.5, and the name is a sample crushing device for food safety testing. The application proposed a Chinese patent with the publication number CN217989463U, which discloses a sample crushing device for food safety testing. After the food sample is crushed, it is inconvenient to clean the filter plate. At the same time, the stability is poor during operation, which leads to the problem that the user's use needs cannot be met. Through the collection tank provided, the collection tank and the filter screen are pulled out from the inside of the crushing box together, and the movable wheel provided is rolled in the limit slot to make the collection The collecting trough can be easily taken out, so that qualified food debris can be taken out, which is convenient for the detection of food samples. At the same time, it is convenient for users to clean the collecting trough and the filter screen, meeting the user's usage needs. However, this application uses a double-roller crushing mechanism. Since the crushing efficiency of the double-roller crushing mechanism is low, the particle size of the food after crushing is large, which is not convenient for direct access operation. Further improvements can be made. At the same time, when unqualified food needs to be crushed for the second time, the staff is required to remove the filter screen and put the unqualified food from the top of the crushing box, which is more troublesome and can be further improved.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
