A tea detection and processing device

Abstract

The invention discloses a tea leaf detection treating device which comprises a detection box, a centrifugal drum and a tea leaf drum, wherein a heating slot with an upward opening is formed in the detection box; a heating plate is arranged on a side wall of the heating slot; a conductive metal pipe is arranged on the outer side of the heating plate; the centrifugal drum is arranged in the heating slot; a conical barrel is connected with the bottom of the centrifugal drum; a detection box cover is arranged at the upper end of the centrifugal drum; the tea leaf drum is connected with the bottom of the detection box cover through a buckle; a water injecting pipe is connected with the detection box cover above the tea leaf drum; an organic reagent box A and an organic reagent box B are connected with the detection box cover; and one organic reagent pipe is respectively connected with the bottoms of the organic reagent box A and the organic reagent box B and is communicated with the centrifugal drum. The tea leaf detection treating device is excellent in sealing property, is capable of increasing the activity of the organic solvent, is capable of increasing the pesticide residue separating effect and efficiency, is capable of realizing full cleaning, is capable of centrifugally treating the water containing pesticide residues, and is convenient to further detect the ingredients and contents of the pesticide residues.

Description

technical field [0001] The invention relates to the technical field of tea detection, in particular to a tea detection and processing device. Background technique [0002] Drinking tea has a long history in my country, and it is called the world's three major beverages together with coffee and cocoa. The tea planting and processing industry has always been a sunrise industry with broad prospects for development. However, in recent years, the problem of pesticide residues in tea has become increasingly serious, and has received widespread attention from all walks of life at home and abroad. Pesticide residues in tea directly cause harm to the human body through brewing, and its potential threat and enrichment effect make it a serious social problem. [0003] At present, the detection of pesticide residues in tea mainly uses large-scale instruments such as gas chromatography, liquid chromatography, gas chromatography-mass spectrometry, and liquid chromatography-mass spectrom...

AI Technical Summary

Problems solved by technology

[0003] At present, the detection of pesticide residues in tea mainly uses large-scale instruments such as gas chromatography, liquid chromatography, gas chromatography-mass spectrometry, and liquid chromatography-mass spectrometry. The instruments are expensive and the operators must have considerable professional skills. The detection cycle is long, which is not conducive to front-line supervision department to popularize

In particular, the extraction process of pesticide residues in tea is quite cumbersome, and it is difficult to achieve sufficient separation of pesticide residues, thereby affecting the detection results. In order to increase the separation of pesticide residues in tea, people increase the amount of organic solvents added to improve the separation effect. Not only does it increase the detection cost, but also a large amount of organic solvents affect the detection of pesticide residues; due to the low water temperature and low activity of organic solvents during the extraction process, the separation cycle of pesticide residues is long, and the detection cannot be separated and detected in time, which affects the detection of tea leaves Efficiency; the separated pesticide residual liquid is mixed with a large amount of tea leaves, which is not convenient for people to extract the residual liquid, which will affect the further detection of pesticide components and content
