Description

A portable pesticide residue detection device

technical field

The utility model relates to a portable pesticide residue detection device, which belongs to the technical field of pesticide detection. the

Background technique

Food safety has become a hot spot that people pay attention to this year. With the enhancement of people's health awareness, pollution-free food is more and more favored by people. In order to make fruits and vegetables attractive, many farmers who grow fruits and vegetables use pesticides to prevent pests or make fruits and vegetables look better. In recent years, food poisoning incidents caused by pesticide residues are common, so people have to be more vigilant and reject fruits and vegetables with excessive pesticide residues. the

Traditional pesticide residue detection methods use gas chromatography, liquid chromatography, etc., which require expensive instruments. Although the test accuracy is high, the test cycle is long, and it is not suitable for shopping malls, homes and other places that require fast and convenient detection. the

Utility model content

The utility model provides a portable pesticide residue detection device, which can conveniently and quickly detect whether the pesticide residue is too high. the

In order to achieve this purpose, the method adopted in the utility model is: a portable pesticide residue detection device, including a sample preparation box, an electric stirring brush is arranged on the top of the sample preparation box, and a sample delivery port is provided on one side of the sample preparation box. The sample port is connected to the test box, and a plurality of test paper slots are arranged in the test box. the

The sample preparation box contains extraction reagents. the

The bottom of the test box is provided with a heating device. the

Its beneficial effects are as follows: put fruit and vegetable fragments into the sample preparation box, start the electric stirring brush to completely brush off the pesticide residues on the fruits and vegetables, insert test paper into the test paper slot, tilt the sample preparation box, and dump the extraction reagent that has extracted the pesticide On the test paper in the test box, use the heating device to heat the test paper for 2-3 minutes, take out the test paper and compare it with the color card to know whether the pesticide residue is too high. the

Description of drawings

The utility model will be explained by way of example and with reference to the accompanying drawings, wherein:

Fig. 1 is a side view structure diagram of the utility model. the

Detailed ways

All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and/or steps. the
