Description

Technical Field

[0001] The utility model relates to the technical field of food pesticide residue detection, in particular to an extraction device for food pesticide residue detection. Background Technique

[0002] Traditional extraction devices for food pesticide residue detection face some significant problems. Existing extraction devices often do not have an automatic cleaning function, which means that manual cleaning is required after each use. This not only takes time and effort but may also affect the accuracy of subsequent detection results due to incomplete cleaning.

[0003] In addition, the efficiency of some devices in extracting the juice from samples is low, resulting in a long sample processing time and affecting the detection speed. During the extraction process, the samples usually need to be fully squeezed to ensure that the pesticide residues in the juice are completely extracted. However, existing devices often cannot effectively apply sufficient pressure to the samples, resulting in insufficient extraction and affecting the reliability of the detection results. Therefore, we have proposed an extraction device for food pesticide residue detection. Content of the Utility Model
