Abstract

The invention discloses a green tea processing technology in the technical field of tea processing. The technology comprises the steps as follows: step 1, picking: step 2, treatment of pesticides: a cleaning barrel comprises a barrel body and a barrel lid, the barrel lid is rotationally connected with a stirring shaft, the stirring shaft is connected with a motor for driving the stirring shaft torotate, the stirring shaft is hollow inside and communicates with multiple stirring blades, multiple air outlet channels are formed in the stirring blades and communicates with the stirring shaft, titanium dioxide layers are smeared on the stirring blades, ultraviolet lamps are arranged on the inner wall of the barrel lid, tea leaves picked in the step 1 are placed in the barrel body, clear wateris added to cover the tea leaves, the motor drives the stirring shaft to rotate, the ultraviolet lamps are turned on, ozone is introduced into the stirring shaft, and the tea leaves are cleaned in thecleaning barrel for 20-30 min, then, fished out and cleaned with clear water; step 3, withering; step 4, fixation; step 5, rolling; and step 6, drying. The organophosphorus pesticide residues can bereduced with the technology.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a green tea processing technology. Background technique [0002] Green tea (Green Tea) is one of the main teas in China. It refers to the beverage made from the new leaves or buds of the tea tree without fermentation, after greening, shaping, and drying. The color of its finished product and the tea soup after brewing mostly preserve the green style of fresh tea leaves. Drinking green tea regularly can prevent cancer, reduce fat and lose weight, and can also reduce the damage of nicotine to smokers. [0003] Green tea is made from the new leaves of the tea tree. After fresh leaves withering-cracking-kneading-unblocking-drying and other typical processes, the function of each step is: fresh leaves withering: fresh leaves are withered, due to moisture Dissipate, the leaf color changes from emerald green to dark green, the leaf quality becomes soft, and the leaf volume beco...
