Example Embodiment

[0022] Example 1

[0023] The far-infrared curing process of granular round-waisted green tea includes the following steps:

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

[0025] S2. Send the withered tea leaves into a kneading machine and press back and forth until the tea leaves are lightly held into a mass, and then dispersed. During the rolling process, the temperature is controlled to 70℃, and then the tea leaves are dispersed and wrapped in the same direction repeatedly to form A granular round-waisted tea leaf with the bud as the core and the leaf wrapping the bud tip;

[0026] S3. Feed the granular round-waisted tea leaves into a drum curing machine equipped with a far-infrared heater, heat up from room temperature at a rate of 1°C / min to 380°C for 2 mi...

[0027] Example 2

[0028] The far-infrared curing process of granular round-waisted green tea includes the following steps:

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

[0030] S2. Send the withered tea leaves into a kneading machine to be rolled back and forth until the tea leaves are lightly held into a mass, and then dispersed. During the rolling process, the temperature is controlled to 60℃, and then the tea leaves are dispersed and wrapped in the same direction repeatedly to form A granular round-waisted tea leaf with the bud as the core and the leaf wrapping the bud tip;

[0031] S3. Feed the granular round-waisted tea leaves into a drum curing machine equipped with a far-infrared heater, and heat up from room temperature at a rate of 3°C / min ...

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...
