Abstract
The present invention relates to the field of tea production and provides a method of withering tea leaves sun, (1) maintaining indoor temperature at 20-25 ℃, relative humidity at 60-70%; (2) spreading fresh tea leaves on a thin bamboo strip water sieve or a bamboo mat, wherein the thickness of the spread fresh tea leaves is not more than 2 cm; the withering time is 12 h-24 h. The natural withering is carried out in a tea leaf thin spreading mode, and the tea leaves with small quantity and high tea leaf grade can be naturally withered; the withering trough withers tea leaves in a thick spreading mode, and withers the tea leaves in two modes of heating hot air and natural air, so that the tea leaves with large quantity are very suitable for withering the tea leaves by a machine in a large quantity; the withering mode provided by the invention can be selected according to actual needs.
Description
Technical Field
The invention relates to the field of tea production, in particular to a withering method of sun-cured green tea.
Background
The sun-dried green tea is a compressed raw material of the Pu' er tea, and the processing technology comprises the steps of enzyme deactivation, rolling and sun drying. After the fresh leaves are picked, the water can be directly removed after reaching the water removing amount of the roller water removing machine. The fresh leaf raw materials are mostly made of summer tea garden raw materials, and are collected mechanically, the raw materials are thick and old, on one hand, moisture of all parts of the raw materials is uneven, enzyme deactivation is easy to explode, and on the other hand, the raw materials are thick and old, are bitter and astringent, and are more prone to highlighting processing peculiar smell.
Disclosure of Invention
The invention provides a withering method of sun-cured green tea, which aims to solve the problems that the existing sun-cured green tea is uneven in moisture due to the fact that tea leaves are thick and old, the green tea is easy to explode when enzyme deactivation is carried out, and the tea leaves are thick and old, heavy in bitter taste and easy to highlight processing peculiar smell.
In order to solve the technical problem, the invention adopts the following technical scheme:
a withering method of sun-dried green tea comprises the following steps:
(1) maintaining the indoor temperature at 20-25 ℃, the relative humidity at 60-70%;
(2) spreading fresh tea leaves on a thin bamboo strip water sieve or a bamboo mat, wherein the thickness of the spread fresh tea leaves is not more than 2 cm; the withering time is 12 h-24 h.
A withering method of sun-dried green tea comprises the following steps:
(1) uniformly spreading fresh tea leaves on a tea leaf withering trough, the thickness of spread fresh tea leaves being 15 cm-20 cm;
(2) adjusting the tea leaf withering mode to a warm air mode, wherein the temperature in the warm air mode is kept within 35 ℃, the temperature keeping time in the warm air mode is 4 h-6 h, and the warm air mode is stopped to use 10 min-20 min before the temperature keeping time is finished;
(3) after the warm air use mode is stopped, the tea leaf withering trough is set to a natural air mode, and the tea leaf temperature is reduced by blowing out natural air in the natural air mode, wherein the use time in the natural air mode is 10 h-12 h.
The invention has the beneficial effects that:
the natural withering is carried out in a tea leaf thin spreading mode, and the tea leaves with small quantity and high tea leaf grade can be naturally withered; the mode that the tealeaves that wither the groove wither and adopt was covered with earth carries out withering, adopts two kinds of modes of warm-air and natural wind to wither, and the tealeaves that volume is big is fit for very much adopting the mode that the machine withered to carry out a large amount of withers.
Detailed Description
