Problems solved by technology

However, the pot temperature of the traditional green tea curing method is relatively high, and the color of the green tea after relatively high temperature curing turns yellow, while low temperature curing can maintain the green color of the green tea, but it is difficult to kill it thoroughly, causing the green tea to turn red.
At the same time, the water content of the green tea after traditional greening is low, and it takes a long time to cool and regain moisture in the process of making flat tea, which prolongs the processing time and reduces the processing efficiency. When the moisture regain temperature is high and the time is too long , will lead to an increase in the yellowness of the tea, a decrease in the greenness and brightness, and an increase in the aroma and taste, which is unfavorable for the industrial production of tea.

Embodiment 1

[0018] A kind of processing technology of flat green tea, comprises the following steps:

[0019] (1) Pick fresh single buds of tea trees, and spread green leaves for 8 hours at a temperature of 30°C and a humidity of 85%, until the color of the tea green leaves turns dark green, and the water content is 73%, and the green leaves are spread;

[0020] (2) Finishing, the process is divided into two stages, the first stage is hot air curing at 300°C, and the second stage is microwave curing at 130°C;

[0021] (3) Moisturize, place the green tea leaves at a temperature of 30-40°C and a relative humidity of 60%-80% for cooling and regaining moisture for 30-45 minutes;

[0022] (4) The flat tea is used as the shaping process, the temperature of the flat tea frying machine is set at 180°C, and the frying time is 20 minutes. Then adopt the traditional secondary drying process (that is, use the 6CTH6 tea drying and aroma enhancing machine, set the initial drying temperature at 110°C, ...

Embodiment 2

[0025] A kind of processing technology of flat green tea, comprises the following steps:

[0026] (1) Pick a new shoot of a tea tree with a bud and a leaf, and spread it green for 7 hours at a temperature of 32°C and a humidity of 78%. When the color of the tea green turns dark green and the water content is 68%, the green leaves are spread;

[0027] (2) Finishing, the process is divided into two sections, the first section is hot air finishing at 290°C, and the second section is microwave finishing at 120°C;

[0028] (3) Moisturize, place the green tea leaves at a temperature of 30-40°C and a relative humidity of 60%-80% for cooling and regaining moisture for 30-45 minutes;

[0029] (4) The flat tea is used as the shaping process, the temperature of the flat tea frying machine is set at 180°C, and the frying time is 20 minutes. Then adopt the traditional secondary drying process (set the initial drying temperature at 110°C, take 20 minutes, dry to a moisture content of 10-15...

Embodiment 3

[0032] A kind of processing technology of flat green tea, comprises the following steps:

[0033] (1) Fresh leaves: Pick the new shoots of tea trees with one bud and two leaves, and spread them green for 6 hours at a temperature of 35°C and a humidity of 65%. When the green color turns dark green and the water content is 65%, green leaves are spread;

[0034] (2) Finishing, the process is divided into two sections, the first section is hot air finishing at 280°C, and the second section is microwave finishing at 100°C;

[0035] (3) Moisturize, place the green tea leaves at a temperature of 30-40°C and a relative humidity of 60%-80% for cooling and regaining moisture for 30-45 minutes;

[0036] (4) The flat tea is used as the shaping process, the temperature of the flat tea frying machine is set at 180°C, and the frying time is 20 minutes. Then use the traditional secondary drying process (the initial drying temperature is set at 110°C, it takes 20 minutes, dry to a moisture co...

Abstract

The invention discloses a novel flat green tea processing technology. The novel flat green tea processing technology comprises the following steps: (1) picking tea shoots, firstly spreading out indoors for removing water until weight percentage of moisture is 65-75%, so that tea leaves with the water removed by spreading out are obtained; (2) carrying out fixation in two stages, wherein in a first stage, high temperature fixation is carried out, and in a second stage, low temperature fixation is carried out; (3) carrying out moisture regaining, namely spreading the tea leaves subjected to fixation for cooling and carrying out moisture regaining under the conditions that temperature is 30-40 DEG C and relative humidity is 60-80%; (4) adopting a flat tea shaping technology, wherein temperature of a flat tea stir-frying machine is set to be 180 DEG C, and stir-frying time is 20 minutes; and (5) drying the obtained tea leaves by adopting the traditional secondary drying process, so that novel flat green tea is obtained. The tea obtained by utilizing the technology is good in sensible quality, flat in shape, jade green or light green in colour, greenish-yellow and bright in liquor colour, fragrant, mellow and brisk or fresh and mellow in taste, and yellow green and bright in infused leaves.

Description

technical field [0001] The invention relates to the technical field of tea, in particular to a green tea processing technology. Background technique [0002] Tea is favored by the world for its natural, nutritious and health-care features, and has become one of the most popular drinks in the world. Green tea is made from the fresh buds and leaves of tea trees, which are refined through processes such as greening, greening, shaping, and drying. In recent years, with the continuous development of global integration, the continuous change of diet and consumption structure, and the continuous promotion of capital circulation, my country's green tea production has maintained rapid development. However, the pot temperature of the traditional green tea curing method is high, and the color of the green tea after relatively high temperature curing turns yellow, while low temperature curing can keep the green color of the green tea, but it is difficult to kill it thoroughly, causing ...
