Description

Oscillating device for pretreatment of detection of pesticide residues in traditional Chinese medicinal materials Technical Field The utility model belongs to the technical field of food detection equipment, and particularly relates to an oscillating device for pretreatment of detection of pesticide residues in traditional Chinese medicinal materials. Background The detection project of the pesticide residue of the traditional Chinese medicine is operated according to the detection requirements of pharmacopoeia, for example, the traditional Chinese medicine sample is crushed, then the extraction solvent is added, the sample solution is prepared through treatment such as shaking and mixing, and then the operations such as purification and detection are carried out. For example, in the treatment of forbidden pesticide residue samples recorded in pharmacopoeia, mixed powder of anhydrous magnesium sulfate and anhydrous sodium acetate is added after the first oscillation treatment, immediately dispersed by shaking, and then vigorously oscillated on an oscillator. Thus, the sample is subjected to a plurality of oscillations, and after each oscillation, a reagent or the like is added for treatment, and then the oscillation is performed again. The shaking-up after adding the reagent is mainly performed manually at present, namely, after the containers are removed, the shaking-up is performed on each container one by one. In addition, in the vibration treatment process, only the pipe frame is used for supporting the sample container, and the conditions of dropping of the container pipe cover, falling of the container out of the pipe frame and the like are easily caused when the vibration amplitude is large.
