Fruit and vegetable residual pesticide detection system

Abstract

The invention relates to the technical field of pesticide detection, in particular to a fruit and vegetable residual pesticide detection system which comprises a separation mechanism, a squeezing mechanism and a stirring mechanism, the squeezing mechanism is installed on the separation mechanism, and the stirring mechanism is installed in the middle of the squeezing mechanism. The separation mechanism comprises a bottom plate, mounting holes, an inner sleeve, an outer sleeve, filter holes, a vertical groove, a rotating pin, a discharge pipe, a sampling pipe, a sampling valve, a flow guide pipe, a regulating valve, a side plate and a top plate, the inner sleeve is fixedly connected to the upper side of the bottom plate, and a plurality of mounting holes are formed in the edge of the bottomplate. According to the fruit and vegetable residual pesticide detection system, the first motor can drive the lifting plate to move up and down in a threaded mode, and when the lifting plate pushes the upper pressing plate to move downwards, the lower pressing plate can be driven to move upwards through the inclined rod and the seesaw, then fruits and vegetables are squeezed, juice can be discharged from the filtering holes and temporarily stored in the gap between the inner sleeve and the outer sleeve after being discharged, and detection and sampling can be conducted only by opening the sampling valve.

Description

technical field [0001] The invention relates to the technical field of pesticide detection, in particular to a detection system for residual pesticides in fruits and vegetables. Background technique [0002] The development of agricultural industrialization makes the production of agricultural products more and more dependent on exogenous substances such as pesticides, antibiotics and hormones. The amount of pesticides used in agricultural products in my country remains high, and the unreasonable use of these substances will inevitably lead to excessive pesticide residues in agricultural products, affecting the safety of consumers, and in severe cases, it will cause consumers to become ill, develop abnormally, and even directly lead to poisoning At present, there are many kinds of rapid detection methods for pesticide residues, which are mainly divided into two categories in principle: biochemical detection method and chromatographic detection method. [0003] In order to fu...

AI Technical Summary

Problems solved by technology

[0003] In order to fully detect the residual amount of pesticides in fruits and vegetables, at present, fruit and vegetable juices are used for colorimetric detection, so as to determine the level of pesticide residues in fruits and vegetables and ensure the safety of agricultural food. However, the existing pesticide squeeze detection equipment uses a single squeeze method The juice collection operation has a low juice yield, and after squeezing the juice, it needs to be cleaned manually, which brings great inconvenience to the detection of pesticide residues in fruits and vegetables
