Description

Technical Field

[0001] The utility model relates to the technical field of fruit and vegetable detection, in particular to a batch sampling and detection device for pesticide residues in fruits and vegetables. Background Art

[0002] Food safety plays a very important role in modern life. Safe and pollution-free food is the most needed guarantee for modern people. However, most fruits and vegetables currently need to be sprayed with pesticides for many times in a row during their growth process before they can mature and be put on the market, and the varieties of pesticides sprayed each time are also very different. The resulting pesticide residues in agricultural products, food and other items are one of the important potential factors that endanger human health, and rapid and efficient detection of pesticide residues is particularly important.

[0003] For example, the publication (announcement) number: CN112098334B discloses a device for detecting pesticide residues in fruits and vegetables, including a mounting frame, a first roller arranged at the lower left end of the mounting frame, a second roller arranged at the lower right end of the mounting frame, and a detection box arranged between the first roller and the second roller, wherein the first roller is wound with a detection film. The present invention can mix a fruit and vegetable solution with a solvent, extract the pesticides from the fruits and vegetables, and drip the solution of the extracted pesticides onto the detection film. The color-changed detection film is detected by a color sensor in the detection box, and the detection result is displayed on a display screen; the invention can guide the sample solution to a small storage tank for storage after the nozzle drips the sample solution onto the detection film. In the process, the sample solution impacts the rotation of the water wheel inside the drain pipe, thereby driving the cleaning brush to rotate and wipe the residue of the sample solution on the nozzle, thereby preventing the detection of other subsequent sample solutions.
