Embodiment 1

[0019] A kind of processing technology of Cui Lan in Yuexi, comprising the steps:

[0020] S1. Withering: Pick a single bud as the main fresh leaf, remove impurities, and place it in the air at 25°C for 3 hours, with a stacking thickness of 1.0cm;

[0021] S2. Ultraviolet radiation: place an ultraviolet emitting light source with an emission wavelength of 280nm directly above the raw material, and the irradiation intensity is 6μW / cm 2 , irradiating once every 10 minutes, each irradiation time is 30s, a total of 6 times of irradiation;

[0022] S3. Finishing: use a drum fixing machine to finish, first at 230°C for 2 minutes, and then at 260°C for 5 minutes;

[0023] S4. Kneading: Take out the green leaves immediately and spread them out until the leaf temperature is 40°C. First, knead them for 2 minutes, then knead them with light pressure for 10 minutes, and finally knead them with heavy pressure for 2 minutes until the tea sticks are tightly rolled and the juice overflows. ...

Embodiment 2

[0026] A kind of processing technology of Cui Lan in Yuexi, comprising the steps:

[0027] S1. Withering: Pick a single bud as the main fresh leaf, remove impurities, and place it in the air at 22°C for 5 hours, with a stacking thickness of 0.5cm;

[0028] S2. Ultraviolet radiation: place an ultraviolet emitting light source with an emission wavelength of 320nm directly above the raw material, and the irradiation intensity is 3μW / cm 2 , irradiate once every 20min, each irradiation time is 15s, a total of 10 irradiations;

[0029] S3. Finishing: use a drum fixing machine for finishing, first at 200°C for 5 minutes, and then at 240°C for 8 minutes;

[0030] S4. Kneading: Take out the fresh leaves immediately after greening, spread out and cool until the leaf temperature is 30°C, knead for 5 minutes in empty space, then knead with light pressure for 5 minutes, and finally knead with heavy pressure for 5 minutes until the tea sticks are tightly rolled, and the juice overflows. W...

Embodiment 3

[0033] A kind of processing technology of Cui Lan in Yuexi, comprising the steps:

[0034] S1. Withering: Pick a single bud as the main fresh leaf, remove impurities, and place it in the air at 24°C for 5 hours, with a stacking thickness of 0.8cm;

[0035] S2. Ultraviolet radiation: place an ultraviolet emitting light source with an emission wavelength of 310nm directly above the raw material, and the irradiation intensity is 5 μW / cm 2 , irradiating once every 18 minutes, each irradiation time is 25s, a total of 9 times of irradiation;

[0036] S3. Finishing: Use a drum fixing machine to fix the greens, first at 220°C for 4 minutes, and then at 255°C for 7 minutes;

[0037] S4. Kneading: Take out the green leaves immediately and spread them out until the leaf temperature is 38°C. Knead for 4 minutes, then knead with light pressure for 9 minutes, and finally knead with heavy pressure for 4 minutes until the tea sticks are tightly rolled and the juice overflows. When it does n...

Abstract

The invention discloses a processing technology of Yuexi Cuilan (a type of green tea). The processing technology comprises the following steps of S1, performing withering: picking single buds as mainfresh leaves, removing impurities, and performing spreading for cooling; S2, performing ultraviolet irradiation: putting an ultraviolet emission light source directly over raw materials, and performing ultraviolet irradiation; S3, performing fixation: performing fixation with a roller fixation machine; S4, performing rolling: immediately taking out the fresh leaves after fixation, performing spreading for heat dissipation, firstly performing pressure-free kneading, then performing kneading under small pressure, and finally performing kneading under large pressure until tea strips are twisted,juice overflows but does not drip; and S5, performing drying: putting the rolled tea strips into a baking machine, performing baking treatment, taking out the baked tea strips, performing spreading for cooling, then putting the cooled tea strips into a frying pan, firstly performing slow frying until the tea strips become reseda, then performing high frying until tea fragrance is generated, and taking out the tea strips out of the pan so as to obtain finished product tea. The Yuexi Cuilan (a type of green tea) prepared by the processing technology disclosed by the invention is excellent in quality, unique in style, emerald green, fresh and living in color of tea leaves, long in delicate fragrance and particularly refreshing in mouth feel.

Description

technical field [0001] The invention relates to the technical field of agricultural processing, in particular to a processing technology of Yuexi cuilan. Background technique [0002] Green tea is one of the main teas in China. It is made without fermentation, so it retains more natural substances of fresh leaves, and contains tea polyphenols, catechins, chlorophyll, caffeine, amino acids, vitamins and other nutrients. There are also more ingredients. These natural nutrients in green tea have special effects on anti-aging, anti-cancer, anti-cancer, sterilization, anti-inflammatory, etc., which are beyond the reach of other teas. Green tea also has shortcomings such as relatively heavy green grass gas and bitter taste in the market at present, causes its market price to be low, causes great loss to tea grower. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a processing technology of ...
