Method for removing pesticide residues from dry tea leaves

Abstract

A method for removing residual pesticide on dried tea leaves relates to a method for removing residual pesticide. The residual pesticide removing step comprises ozone-oxygenation-ultraviolet rays-anion. The method can remove a plurality of fussy residual pesticide removal methods in tea trees, tea gardens and the like, can successfully remove the residual pesticide quantity of the dried tea leaves, completely reaches export standards of the tea leaves after being detected by a 'tea leaf residual pesticide tachymeter', saves labor force, obviously improves effects and efficiency and is suitable to green tea, black tea, oolong tea and the like.

Description

technical field [0001] The invention relates to a method for removing pesticide residues, in particular to a method for removing pesticide residues through dry tea leaves. Background technique [0002] Tea is an edible beverage that people drink daily, if there are excessive pesticide residues in the tea. It will seriously affect people's physical and mental health and cause immeasurable harm to the human body. Therefore, it is of great significance to remove pesticide residues in tea. [0003] There are pesticide residue removal products on the market, and the working environment must be carried out in a liquid (liquid phase). Dry tea leaves with excessive pesticide residues are not allowed to remove pesticide residues in the liquid phase, because the tea leaves will be leached out immediately when soaked in water. The ingredients of tea leaves are turned into tea water, and then dried into dry tea leaves can only be tea dregs, so it is not feasible to remove pesticid...

Problems solved by technology

[0006] The above three methods of deworming and detoxification have little effect and cannot be popularized. The reasons are: 1. Apply stickers to tea trees: one: rain, exposure to the sun or dust will affect the effect; control; third: high labor costs

2. Insecticidal lamps: first: crawling pests cannot be controlled; second: many flying insects are not interested in insecticidal lamps; third: insecticidal lamps are easy to be stolen in the wild; fourth: reptiles are still rampant

There are three defects in this method: 1) The cost of special bacteria is high; 2) The labor cost is high for each spraying; 4) The surrounding tea gardens are sprayed with poison, and I am the only one who washes the poison first.
