Embodiment 1

[0018] Example 1. A kind of green tea processing method, carry out according to the following steps:

[0019] a. Spread green: feed green tea in green stand machine with feeding speed of 0.2~0.4m / min and feeding density of 4~6kg / m 2 Send it down to the drying rack and spread it to cool naturally, so that the water content of the green tea is reduced to 60% to 65%, and the product A is obtained;

[0020] b. Finishing: put product A into the greening machine for finishing, and the feeding amount is controlled at 80-100kg / h; the temperature of the inlet of the killing machine is controlled at 300-320°C, and the temperature of the outlet is controlled at 280-290°C. After the time control of the drum of the greening machine is controlled for 6-8 minutes, the speed of the drum of the greening machine is controlled at 20-30r / min, and product B is obtained after greening;

[0021] c. Initial kneading: put product B into the kneading machine for initial kneading. During the initial k...

Embodiment 2

[0025] Example 2. A kind of green tea processing method, carry out according to the following steps:

[0026] a. Spread green: feed green tea in green stand machine with feeding speed of 0.2~0.4m / min and feeding density of 4~6kg / m 2 Send it down to the drying rack and let it cool naturally, so that the water content of the green tea is reduced to 62% to 64%, and the product A is obtained;

[0027] b. Finishing: put product A into the greening machine for finishing, and the feeding amount is controlled at 80-100kg / h; the temperature of the inlet of the killing machine is controlled at 305-310°C, and the temperature of the outlet is controlled at 285-288°C. After the time control of the drum of the greening machine is controlled for 6-8 minutes, the speed of the drum of the greening machine is controlled at 20-30r / min, and product B is obtained after greening;

Abstract

The invention discloses a green tea processing method. The method comprises the following steps of: a, spreading green tea: naturally spreading the green tea to cool naturally, and reducing the watercontent of the green tea to 60-65 % to obtain a product A; b, de-enzyming: putting the product A into a de-enzyming machine for de-enzyming, wherein the feeding amount of the product A is controlled to be 80-100 kg / h during de-enzyming; controlling the feeding port temperature of the de-enzyming machine to be 300-320 DEG C, controlling the discharging port temperature to be 280-290 DEG C, and obtaining a product B after de-enzyming; c, primarily kneading: putting the product B into a kneading machine for primarily kneading for 8-10 min, and obtaining a product C; d, drying and dehydration: drying the product C at 90-100 DEG C and reducing the water content of leaves to 35-40 %, and obtaining a product D; e, rekneading: putting the product D in a tea kneading machine and twisting for 15-20min to obtain a product E; f, drying: drying the product E in a continuous microwave dryer, reducing the water content of leaves to 3-5 %, screening out crushed leaves to obtain the green tea. The green tea processing method has the advantages of stable production quality, sweet taste of the product, good sweet returning characteristic, strong fragrance and beautiful tea shape of the product.

Description

technical field [0001] The invention relates to the technical field of tea production, in particular to a green tea processing method. Background technique [0002] Green tea, also known as non-fermented tea, is made from new shoots of tea trees through basic processes such as greening, rolling, and drying. The finished product, tea soup, and leaf bottom are all green, so it is called green tea. . Green tea is not fermented during processing and retains the natural substances of fresh leaves. It contains more nutrients such as tea polyphenols, catechins, chlorophyll, caffeine, amino acids, and vitamins. Cancer, anti-cancer, bactericidal, anti-inflammatory, etc. have special effects, which are beyond the reach of other teas, so they are currently a popular type of tea. In green tea, Duyun Maojian is shaped like a strip, its color is green with yellow, and there are many pekoe. The tea is sweet and refreshing. Because of its beautiful shape, fragrant and sweet smell, and un...
