[0002] Before making raisins, grapes usually need to be washed to remove surface dirt and pesticide residues. However, if the washing is not thorough or the method is inappropriate, some pesticides may remain on the grapes. In addition, different drying methods have different effects on pesticide residues. During transportation, if raisins come into contact with other items that may contain pesticide residues, secondary contamination may also occur.

This preparation method is prone to dosage control errors due to the large number of manual uncertainties, resulting in inaccurate test results. At the same time, when the raisins are mixed with the solvent, the reaction container is mostly shaken manually to accelerate the mixing reaction. This mixing method is very physically demanding, so it is very necessary to provide a pesticide residue detection device. Utility Model Content

[0011] Preferably, a pesticide residue detector is fixedly installed on the top of the workbench.
