Problems solved by technology

This process makes the tea products into strips by rolling twice, and then mechanically sieves the length and thickness of the tea products as the basis for grading the tea products. The obtained tea products have no clear requirements on the appearance, that is, It doesn't matter how beautiful the appearance of the tea is
[0004] In addition, using the de-greening conditions disclosed in the above process, the process is complicated and requires high requirements for operators; using the re-frying process, the tea products are directly in contact with the pot, and the phenomenon of scorched edges and sticky leaves is prone to occur, and the tea juice is easy to stick to the pot Produce burnt gas, also affect the color and aroma of tea

Embodiment 1

[0019] Embodiment 1: a kind of preparation method of needle-shaped green tea:

[0020] A. Material selection: Use the fresh tea leaves of the small and medium-sized leaves picked in spring as raw materials;

[0021] B. Steam heat treatment: 6CZS-50 steam heat treatment machine is used for steam heat treatment, the steam temperature is 90°C, the thickness of fresh leaves is 10 mm, and the time of treatment is 80 seconds, so as to ensure that the high-temperature steam can quickly penetrate the fresh tea leaves. Evenly increase the temperature of fresh tea leaves, passivate the activity of polyphenol oxidase in fresh tea leaves, maintain the green color of tea leaves, and the water content of the finished product is about 60%;

[0022] C. Preliminary rolling: spread out the green leaves with a water content of about 60% and then carry out preliminary rolling, using a 6CR-30 rolling machine, rolling and adding pressure according to the light-heavy-light principle commonly used in...

Embodiment 2

[0026] Embodiment 2: a kind of preparation method of needle-shaped green tea:

[0027] A. Material selection: the raw material of fresh tea leaves is selected from the fresh leaves with one bud and one leaf of the medium and small leaf group species;

[0028] B. Green spreading: put fresh tea leaf raw materials in a ventilated room, and spread them with a clean bamboo dustpan with a thickness of 20mm for about 6 hours;

[0029] C. Steam-heating: 6CZS-50 steam-heating machine is used for steam-heating, the steam temperature is 140°C, the thickness of fresh leaves is 15 mm, and the time for curing is 20 seconds. The water content of the finished product is about 60%;

[0030] D. Initial rolling: spread the green leaves with a water content of about 60% to dry, and then carry out initial rolling. Using a 6CR-30 rolling machine, according to the principle of light-heavy-light, light and heavy are alternately rolled, and the rolling time is 45 minutes. The rate of making buds and ...

Embodiment 3

[0035] Embodiment 3: a kind of preparation method of needle-shaped green tea:

[0036] A. Material selection: The raw material of fresh tea leaves is the young buds and leaves of small-leaf tea tree varieties;

[0037] B. Green spreading: put fresh tea leaf raw materials in a ventilated room, and spread them with a clean bamboo dustpan with a thickness of 65mm for about 6 hours to 8 hours;

[0038] C. Steam-heating: use 6CZS-50 type steam-heating machine for steam-heating, the steam temperature is 135°C, the thickness of the fresh leaf feed is 15mm, and the drying time is 30 seconds. The water content of the finished product is about 60%;

[0039] D. Spreading and airing: Use electric fans to quickly cool the tea products to room temperature;

[0040] E. Initial kneading: spread out the green leaves with a water content of about 60% and then perform the initial kneading, using a 6CR-30 kneading machine, according to the principle of light-heavy-light, kneading alternately bet...

Abstract

The invention discloses a preparation method of needle-shaped green tea. It is the raw materials of fresh tea leaves through material selection, steam heating, primary rolling, re-rolling, shaping, and drying to the finished product; wherein the shape is made into a needle shape by pruning or / and rubbing. The needle-shaped green tea provided by the invention has a tight, straight and delicate shape, clear and bright green soup, fresh and tender aroma, fresh and mellow taste, and is a high-quality green tea with taste and ornamental value in shape, color, aroma and taste.

Description

technical field [0001] The invention relates to a method for preparing green tea, in particular to a method for preparing needle-shaped green tea. Background technique [0002] With the improvement of people's living standards, people's requirements for the quality of tea are getting higher and higher. Drinking tea is no longer just about quenching thirst. The "tea culture" of the country requires tea to have tasting and ornamental value in terms of shape, color, aroma, and taste. And tea is a kind of complex and comprehensive technical product. The shape, color, aroma and taste of tea are not only related to the quality of fresh tea leaves, especially the shape of tea, but also depend on different tea processing techniques. Therefore, tea making technology is the guarantee. The key to tea quality. [0003] The processing technology of existing green tea, as " a kind of preparation method of green tea " announced in CN1033204C, its process step is: steam fixation, physical...
