Pesticide residue detection pretreatment device

Abstract

The invention discloses a pesticide residue detection pretreatment device, and belongs to the field of food detection devices. The device comprises a first centrifuge tube rack, a second centrifuge tube rack, a third centrifuge tube rack, a first centrifuge tube cap screwing movement device, a first liquid adding movement device, a second liquid adding movement device, a first liquid sucking and liquid adding movement device, a third liquid adding movement device, a second centrifuge tube cap screwing movement device, a second liquid sucking and liquid adding movement device and a third centrifuge tube cap screwing movement device; and the first centrifuge tube rack, the second centrifuge tube rack and the third centrifuge tube rack are all arranged on a conveyor belt. Under the control ofa control mechanism, the pesticide residue detection pretreatment process can be automatically completed in batches, the manual operation is replaced, and the pesticide residue detection pretreatmentwork can be completed in batches, so that the working efficiency and quality are improved and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the field of food detection devices, in particular to a pesticide residue detection pretreatment device. 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 causes of excessive pesticide residues in vegetables are organophosphorus pesticides and carbamate pesticides that are prohibited from being used in vegetable production in some countries, such as methamidophos, omethoate, phorate, parathion, and methyl parathion Wait. Eating food containing a large amount of highly toxic and highly toxic pesticide residues can lead to acute poisoning accidents in humans and animals. Although long-term consumption of agricultural by-products with excessive pesticide residues will not cause acute poisoning, it may cause chronic poisoning in humans and anim...

Problems solved by technology

[0006] Due to the large number of samples, the pretreatment work is complicated and time-consuming, the operation is manual, the labor intensity is high, human errors often occur, and the work quality and efficiency are not high. At present, there is no one that can replace human operations to complete large batches of pretreatment work. automation device
