Description

Pesticide residue detection and analysis device Technical Field The utility model relates to the technical field of pesticide residue detection, in particular to a pesticide residue detection and analysis device. Background The development of agricultural industrialization makes the production of vegetables more and more depend on pesticide, antibiotics, hormone and other foreign substances, the consumption of the pesticide in China is high, and unreasonable use of the substances can lead to exceeding of pesticide residues in the vegetables, influence on the edible safety of consumers, and cause pathogenicity, abnormal development and even direct poisoning death of the consumers when serious. When detecting pesticide residue, a detection analyzer is needed The utility model with the publication number of CN213398179U provides a wild fungus pesticide residue detection and analysis device, which comprises a shell and an analysis mechanism, wherein a dosing hole is formed in the side face of the shell between a slag discharging connecting pipe and a liquid discharging connecting pipe, a sealing cover plate is transversely arranged at the upper end of the front side surface of the shell on one side of a voice prompt device, a crushing chamber is arranged on the inner wall of the shell below the sealing cover plate, the analysis mechanism comprises a crushing roller, a solid-liquid separator, a catalytic tank and a spectrophotometer, a driven roller is transversely arranged on the inner wall of the crushing chamber on one side of the crushing roller, and the spectrophotometer is transversely arranged on the front side surface of one end of the shell far away from the sealing cover plate. The utility model utilizes the variable frequency motor to control the grinding roller to rotate so as to match with the driven roller to complete the grinding operation, the ground bacterial material completes the separation and extraction of bacterial liquid in the solid-liquid separator, and the bacterial material is conveyed into the detection tube of the spectrophotometer after the catalytic reaction in the catalytic tank to complete the pesticide concentration analysis.
