Problems solved by technology

In order to solve this problem, black tea raw materials must be reproduced and fermented in the production of dark tea products. Although how to reproduce the fermentation process, the effect is not ideal for black hair tea that has not changed color, not only does not remove the green and astringent taste, but also Increases the fermented flavor of the mound

Embodiment 1

[0024] Example 1: The preparation method of non-fire-roasted dried black hair tea, including killing greens, kneading, stacking, fermenting, re-kneading, and drying. The special features are:

[0025] Said enzymatic fixation: Spray water on the fresh leaves of the tea leaves to saturate the water on the surface of the tea leaves, and control the fixation temperature to at least 320°C.

[0026] Said drying: non-fire roasting is adopted, when the tea leaves are dried to 5-9 or 6-8 or 70% dry, they are re-moisturized and heaped and fermented, and then dried into black hair tea.

[0027] After resurfacing and fermenting, it is sorted and then dried into black hair tea. This can solve the problem that the dryer-dried tea and the sun-dried tea cannot be separated.

[0028] Described kneading: be to knead again after the green leaves are spread out to cool.

[0029] Before finishing, preheat the finishing machine so that the wall temperature of the finishing cylinder reaches 400-55...

Embodiment 2

[0038] Embodiment 2: The preparation method of non-fire-roasted dried black hair tea, which is followed by deenzyming, rolling, stacking, fermenting, re-kneading, and drying.

[0039] The degreening machine is generally a general-purpose degreening machine. The black tea raw materials are much thicker and older than the green tea raw materials, and the black tea raw materials are more difficult to degreen. If you follow the green tea decapping parameters, it is often impossible to decapitate. In order to kill the tea leaves thoroughly and avoid red and yellow leaves, spray water on the fresh leaves of the tea leaves to saturate the water on the surface of the tea leaves until there are water droplets on the tea leaves. The water is mountain spring water. Before finishing, preheat the finishing machine so that the wall temperature of the finishing cylinder reaches 440°C before cutting. In the finishing process, the finishing temperature is 320-400°C, the green stem tea is used...

Embodiment 3

[0050] Embodiment 3: The preparation method of non-fire-roasted dried black hair tea, which is followed by deenzyming, rolling, stacking, fermentation, re-kneading, and drying,

[0051] In order to kill the tea leaves thoroughly and avoid red and yellow leaves, spray water on the fresh leaves of the tea leaves to saturate the water on the surface of the tea leaves until there are water droplets on the tea leaves. The water is mountain spring water. Before finishing, preheat the killing machine so that the wall temperature of the killing cylinder reaches 480°C. In the finishing process, the finishing temperature is 340-450°C, the green stem tea is used at a low temperature, which is controlled at 340-365°C, and the flower stem tea or red stem tea is used at a high temperature, which is controlled at 410-435°C. The de-enzyming temperature refers to the de-enzyming cylinder wall temperature during the de-enzyming process.

[0052] The amount of feeding should be uniform when fi...

Abstract

The invention provides a preparation method of raw dark green tea through non-fire roasting drying and the prepared raw dark green tea, and relates to a processing method of the raw dark green tea and the raw dark green tea. The method comprises the steps of fixation, rolling, pile fermentation, fermentation, rerolling and drying. The method is characterized in that when fixation is conducted, fresh tea leaves are sprayed with water to enable moisture on the surfaces of the tea leaves to be saturated, and the fixation temperature is controlled to at least 320 DEG C. The produced raw dark green tea prepared through the method is jet-black, uniform in color and luster, compact in strip, red-yellow in liquor color, sweet, mellow and free of smoky flavor; when the raw dark green tea is used as the raw material for producing black tea products, raw material reproduction is not needed, the production step is simplified, energy consumption is reduced, the production cost is reduced, the produced black tea products do not need to be stored for aging, and the black tea products can go on sale in the current year after being produced.

Description

technical field [0001] The invention relates to a processing method of black hair tea and black hair tea. Background technique [0002] As a healthy drink, black tea is not only the essential tea of ​​life for the three meals of nomads, but it is also more and more loved by inland people and has become a consumption fashion. Black tea is a traditional product, and the drying method used in the past is Qixingzao pine firewood to dry, such as patent publication number: CN101084771, publication date: 2007.12.12 a kind of preparation method of Qianliang tea, the disclosed technology is : "The processing procedure of black tea raw materials is: picking fresh leaves → greening → kneading → fermenting → re-kneading → baking". For this fragrance, in order to meet the needs of new consumers, many manufacturers use hot air drying and sun drying. Although hot-air drying and sun-drying do not have the smoky flavor of pine and wood, the black hair tea produced has no strands, grayish-g...
