Description

Technical Field

[0001] The present invention relates to the technical field of pesticide residue detection, and in particular to a device and method for detecting pesticide residue in vegetables. Background Art

[0002] In the process of vegetable cultivation, in order to avoid pests and ensure yields, organophosphorus pesticides, carbamate pesticides, pyrethroid pesticides or organochlorine pesticides are used for pest control. However, the pesticides are sprayed on the surface of the vegetables. Before the vegetables are picked and sold, there will be more or less pesticide residues on the surface of the vegetables. If the pesticide residues exceed the standard, people will be endangered when eating them. Therefore, in order to ensure the safety of vegetable food, it is very necessary to test the vegetables for pesticide residues.

[0003] The Chinese utility model patent with the patent number CN202322595035.1 discloses a pepper pesticide residue detection device, which relates to the field of pesticide residue detection technology, including a box body, the inner side wall of the box body is connected to a barrier, the interior of the box body is respectively provided with a soaking chamber and a detection chamber, the inner side wall of the soaking chamber is connected to a storage unit, and the device cooperates with the movable block, the protrusion and the limit groove through the storage frame and the pressure plate. The above structure increases the contact time between the pepper and the water by completely immersing the pepper in the detection water, and the pesticides remaining on the surface of the pepper can be immersed in the water. Although increasing the immersion time of the pepper has a certain effect on extracting residual pesticides, in addition to the residual pesticides on the surface of the vegetables, some water-soluble pesticides may also penetrate into the vegetable tissues. Only detecting the soaking water cannot accurately detect the amount of pesticides remaining in the vegetables.

A method for detecting drug residues in vegetables, using the detection device according to any one of claims 1 to 8, characterized in that: The top cover (14) is opened, and vegetables are placed into the two crushing chambers (18) respectively. The top cover (14) is closed, and the first motor (32) is controlled to operate so that the crushing detection barrel (4) moves back and forth between the two crushing chambers (18) to impact and crush the vegetables. When the crushing detection barrel (4) moves to a state closest to one of the arc-shaped side plates (16), the second motor (51) is controlled to operate, and the blocking plate (46) and the pressing plate (43) move vertically downward so that the pressing plate (43) squeezes the crushed vegetables, the connecting cover (48) is connected to the filter port (42), and the detection liquid is received in the detector (49) for pesticide residue detection.
