Problems solved by technology

[0003] Because the raw materials used in granular round-waist green tea have leaves, buds, and stems, and the volumes of leaves, buds, and stems vary greatly, it is easy to cause tender parts such as leaves and bud tips to be damaged by temperature. If the temperature is too high, burnt flakes and leaves will appear, but the inside of the tea stem in the center will not be killed due to the low temperature, which will seriously affect the formation of good aroma, soup color and taste.

Embodiment 1

[0023] Granular round waist shape green tea far-infrared green-fixing process comprises the following steps:

[0024] S1. Pick fresh leaf raw materials containing one bud and one leaf, spread them evenly on the bamboo plaque, with a thickness of 0.5cm, and then wither at 25°C, with a withering humidity of 66%, and a withering time of 6 hours, and stir every 20 minutes withering once;

[0025] S2. Put the withered tea leaves into the kneading machine and roll them back and forth until the tea leaves are lightly gripped into a ball, and then loosen after light pressing. During the rolling process, the temperature is controlled at 70°C, and then the tea leaves are dispersed and wrapped repeatedly in the same direction to form Granular round waist-shaped tea leaves with the bud as the core and the leaf wrapping the tip of the bud;

[0026] S3. Send the granular round waist-shaped tea leaves into the drum fixing machine equipped with a far-infrared heater, raise the temperature fr...

Embodiment 2

[0028] Granular round waist shape green tea far-infrared green-fixing process comprises the following steps:

[0029] S1. Pick fresh leaf raw materials containing one bud and one leaf, spread them evenly on the bamboo plaque, with a thickness of 1.5cm, and then wither at 20°C, with a withering humidity of 70%, and a withering time of 4 hours, and stir every 30 minutes withering once;

[0030] S2. Put the withered tea leaves into the kneading machine and roll them back and forth until the tea leaves are lightly gripped into a ball, and then loosen after light pressing. During the rolling process, the temperature is controlled at 60°C, and then the tea leaves are dispersed and wrapped repeatedly in the same direction to form Granular round waist-shaped tea leaves with the bud as the core and the leaf wrapping the tip of the bud;

[0031] S3. Send the granular round waist-shaped tea leaves into the drum fixing machine equipped with a far-infrared heater, raise the temperature fr...

Embodiment 3

[0033] Granular round waist shape green tea far-infrared green-fixing process comprises the following steps:

[0034] S1. Pick fresh leaf raw materials containing one bud and one leaf, spread them evenly on the bamboo plaque, with a thickness of 0.6cm, and then wither at 24°C, with a withering humidity of 67%, and a withering time of 5.5h, wherein each withering is 22min Flip once;

[0035] S2. Put the withered tea leaves into the kneading machine and roll them back and forth until the tea leaves are lightly gripped into a ball, and then loosen after light pressing. During the rolling process, the temperature is controlled at 68°C, and then the tea leaves are dispersed and wrapped repeatedly in the same direction to form Granular round waist-shaped tea leaves with the bud as the core and the leaf wrapping the tip of the bud;

[0036] S3. Send the granular round waist-shaped tea leaves into the drum fixing machine equipped with a far-infrared heater, raise the temperature from...

Abstract

The invention discloses a granular round kidney-shaped green tea far-infrared fixation technology. The technology comprises the following steps: picking a fresh leaf raw material containing one bud and one leaf, uniformly spreading the raw material on a bamboo basket, then, carrying out withering at 20-25 DEG C at a withering humidity of 66%-70% for 4-6 h; sending the withered tea in a rolling machine to be ground back and forth until the tea forms balls by slight holding and disperses by slight pressing, then, dispersing the tea, and repeatedly covering the tea in the same direction to form granular round kidney-shaped tea with buds as cores and leaves covering bud tips; performing far-infrared fixation on the granular round kidney-shaped tea, increasing the temperature from the room temperature to 340-380 DEG C at a speed of 1-3 DEG C / min, carrying out fixation for 2-4 min, then, increasing the temperature 400-450 DEG C at a speed of 2-4 DEG C / min continuously, performing fixation for 1-2 min and baking, and slowly decreasing the temperature to room temperature to obtain the granular round kidney-shaped green tea. The technology can damage the activity of passivation oxidase, sothat the tea has stronger aroma, clearer color and mellower taste.

Description

technical field [0001] The invention relates to the technical field of tea deep processing, in particular to a far-infrared degreening process of granular round-waist green tea. Background technique [0002] The greening of fresh leaves is to destroy and passivate the oxidase activity in fresh leaves by high temperature, inhibit the enzymatic oxidation of tea polyphenols in tea leaves, soften the tea leaves by evaporating part of the water in fresh leaves, and make the tea leaves emit a fragrant smell. In order to promote the formation of good aroma and taste, so finishing is the key process of preparing green tea. [0003] Because the raw materials used in granular round-waist green tea have leaves, buds, and stems, and the volumes of leaves, buds, and stems vary greatly, it is easy to cause tender parts such as leaves and bud tips to be damaged by temperature. If the temperature is too high, scorched flakes and leaves will appear, but the inside of the tea stem in the cen...
