[0002] As people's quality of life continues to improve, more and more people are beginning to pay attention to food safety issues and have higher requirements for the detection of pesticide residues in food. The detection methods currently on the market are cumbersome and expensive, and most require professionals with a certain level of operational skills to perform the test. Currently, there are not many people in the market who meet these operating specifications, making it difficult to meet the needs of most people. Therefore, there is an urgent need for an automated pesticide residue detection device to meet the needs of the public.

[0003] A search revealed a Chinese patent document that discloses an automatic pesticide residue detection device [Application Number: 202122506088.2; Publication Number: CN215985756U]. This automatic pesticide residue detection device comprises a frame assembly, a beaker assembly, and a pesticide detector. The beaker assembly is mounted within the frame assembly, and the pesticide detector is mounted at the bottom of the frame assembly. The beaker assembly includes a volumetric flask, a buffer beaker, a substrate beaker, a cholinesterase beaker, a developer beaker, a test liquid beaker assembly, a blank control liquid beaker assembly, a test mixed liquid beaker assembly, and a solenoid valve. The beakers are connected by pipes with solenoid valves, which are distributed from top to bottom on the frame assembly. The solenoid valve, the test liquid beaker assembly, the blank control liquid beaker assembly, and the test mixed liquid beaker assembly are all electrically connected to the pesticide detector. A control device controls the flow of liquid within the device via the solenoid valve, making it simple and easy to operate.

[0004] The control device disclosed in this patent controls the flow of liquid in the device through a solenoid valve. Although it is simple and easy to operate, the device has a low degree of automation and requires users to prepare the detection reagents themselves, and has a small scope of application.

[0005] Therefore, we propose an automatic pesticide residue detection instrument for fruits, vegetables and meat, which can automatically transport fruits, vegetables and meat, quantitatively sample, efficiently extract, quickly and safely detect pesticide residues, and has a wide range of applications.
