Processing technology of green tea

Abstract

The invention belongs to the technical field of tea leaf processing technologies and in particular relates to a processing technology of green tea. The technology comprises the following steps: spreading tea leaves on a spreading machine in a spreading room for 5 to 8h; setting the spreading machine to automatically overturn the leaves for one time every hour; meanwhile, mounting an air exhaust fan on a wall of the spreading room to ensure ventilation of the spreading room; carrying out fixation on the tea leaves by utilizing a roller fixation machine; passivating the activity of an enzyme through a high-temperature manner, so as to damage tissues and structures in the tea leaves to change the property of fresh leaves, and improve the quality of the tea leaves; stirring and frying the tealeaves through tea leaf screening, stirring and frying equipment to dissipate water steam and grass gas in the tea leaves, so as to enable the tea leaves to be easily stored; sealing and packaging thetea leaves through a tea leaf packaging machine to separate the tea leaves from external air, so as to prevent the quality of the tea leaves from being influenced and enable the tea leaves to be preserved for long time. The processing technology of the green tea is applicable to large-scale processing of the green tea and the processed green tea has good quality.

Description

technical field [0001] The invention belongs to the technical field of tea processing technology, 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. The processing of traditional green tea is usually manual processing, the processing speed is slow, and it is impossible to process large quantities of green tea. At the same time, the processed green tea cannot be packaged in time, resulting in a decline in the quality of green tea; when green tea is processed, how to effectively process green tea? The finishing a...
