[0002] The problem of pesticide residues arises with the mass production and widespread use of pesticides. After pesticides are applied in agricultural product production, some of the pesticides remain directly or indirectly in vegetables and fruits. Pesticide residues directly reach the human body through vegetables and fruits, or are ultimately passed on to humans through the environment and food chain. Pesticide residues can also accumulate in the human body. When they exceed a certain amount, they will endanger human health and induce some diseases. Therefore, it is very necessary to detect the safety of pesticide residues in fruits and vegetables.

[0003] When testing for pesticide residues in fruits and vegetables sold in the market, various types of fruit and vegetable products will be randomly selected, bagged and taken back to the testing agency as samples for testing. In the experiment, the fruit and vegetable products to be tested need to be pre-processed in advance, that is, the fruit and vegetable products are chopped and put into a grinder for crushing, and then a certain number of grams of products are extracted for testing. When testing for pesticide residues, there are often more than one fruit and vegetable products that need to be tested. The existing experimental grinders can only crush one product, and after the crushing process, they need to be cleaned before crushing another product to prevent cross-contamination of samples. Therefore, the testing process is not only complicated, but also time-consuming and the testing efficiency is not high. To this end, in response to the above problems, we provide a grinder for safe testing of fruit and vegetable pesticide residues, which is used to improve the crushing efficiency before fruit and vegetable pesticide residue safety testing.
