Problems solved by technology
[0003] Existing pesticides can be divided into fat-soluble and water-soluble according to their solubility. However, the existing detection devices for pesticide residues need to add non-polar and polar solvents to extract pesticide residues in fruits and vegetables, which cannot be used for fat-soluble pesticides. Simultaneous extraction with water-soluble pesticides, low work efficiency

The invention discloses a fruit and vegetable pesticide residue detection device with double mixing chambers: it includes a mounting frame, a fruit and vegetable storage tank arranged on the top of the mounting frame, and a fruit and vegetable crushing box and a mixing box arranged on a loading plate at the bottom of the mounting frame in sequence from top to bottom. A reaction box, the sample solution output port of the mixing reaction box is connected to the input end of a small pump through an infusion tube, and the output end of the small pump is connected to a pesticide residue analyzer. The invention can simultaneously extract water-soluble pesticides and fat-soluble pesticides in fruits and vegetables, and improve the detection efficiency of pesticides remaining in fruits and vegetables. The invention can impact fruits and vegetables through the shell of the vibrating impact head, and cooperate with the sharp crushed material net to squeeze and cut off the fruits and vegetables, so that the fruits and vegetables are crushed and extruded from the mesh holes of the crushed material net, so as to realize uniform fine crushing for subsequent Solvents allow better mixing of pesticides.
Description
technical field [0001] The invention relates to the technical field of pesticide detection equipment, in particular to a double-mixing chamber pesticide residue detection device for fruits and vegetables. Background technique [0002] Pesticide residue refers to the general term of pesticide parent, derivatives, metabolites, degradation products and impurities that remain in the environment, organisms and food after pesticide use. The main cause of excessive pesticide residues in vegetables is the pesticides banned in vegetable production in some countries. The food caused by pesticide residues will lead to acute poisoning accidents of humans and animals. [0003] Existing pesticides can be divided into fat-soluble and water-soluble according to their solubility. However, the existing detection devices for pesticide residues need to add non-polar and polar solvents to extract the pesticide residues in fruits and vegetables, which cannot be used for fat-soluble pesticides. S...
