Problems solved by technology

The greening of tea includes roller fixing and microwave fixing. The aroma of tea leaves obtained by roller fixing is pleasant, but it often appears that the fixing is not transparent and uneven; microwave fixing can heat the inner and outer surfaces of the tea at the same time, and the fixing is thorough and even. But the aroma of the tea obtained is not enough

Embodiment 1

[0021] Embodiment 1: a kind of green tea processing technology, comprises the following steps:

[0022] a. Picking fresh leaves: Picking fresh tea leaves with one bud and one leaf as green tea raw materials;

[0023] b. Withering: Place the fresh leaves in the room to wither naturally for 60-70 minutes, then wither in hot air at 80°C for 40-50 minutes; repeat the operation until the water content of the withered leaves is 50%;

[0024] c, cooling: utilize the cold wind of temperature 10~15 ℃ to cool to the temperature of withered leaf is 15~20 ℃;

[0025] d. Finishing: Transfer the cooled withered leaves to a drum cleaning machine for one cleaning. The temperature of the drum cleaning machine is 100-120°C, and the cleaning takes 40 seconds; take it out and spread it in a dustpan, and quickly transfer it to a microwave cleaning machine after 5 minutes. Carry out secondary greening, the temperature of the microwave greening machine is 80-90°C, and the greening time is 2-3 minut...

Embodiment 2

[0031] A kind of green tea processing technology, comprises the following steps:

[0032] a. Picking fresh leaves: Picking fresh tea leaves with one bud and one leaf as green tea raw materials;

[0033] b. Withering: Place the fresh leaves indoors to wither naturally for 60-70 minutes, then wither in hot air at 60°C for 40-50 minutes; repeat the operation until the water content of the withered leaves is 45%;

[0034] c, cooling: utilize the cold wind of temperature 10~15 ℃ to cool to the temperature of withered leaf is 15~20 ℃;

[0035] d. Finishing: Transfer the cooled withered leaves to a drum cleaning machine for one cleaning. The temperature of the drum cleaning machine is 100-120°C, and the cleaning takes 35 seconds; take it out and spread it in a dustpan, and quickly transfer it to a microwave cleaning machine after 10 minutes. Carry out secondary greening, the temperature of the microwave greening machine is 80-90°C, and the greening time is 2-3 minutes;

Abstract

The invention discloses a green tea processing process, belonging to the technical field of tea processing. The green tea processing process comprises the following steps: putting picked fresh leaves into a room to naturally wither, and then withering the leaves in hot air; repeatedly operating until moisture of the withered leaves is 45-55%; cooling by utilizing cold air until temperature of the withered leaves is 15-20 DEG C; transferring the cooled withered leaves into a roller water-removing machine for primary water-removing; taking out and spreading the leaves in a dustpan, and quickly transferring the leaves into a microwave water-removing machine for secondary water-removing 5-10 minutes latter; taking out and putting the water-removed tea leaves into a pan to stir-fry, and taking out the tea leaves after stir-frying for 3-5 minutes, wherein the temperature of the pan is 60-70 DEG C; rolling; drying; and putting the dried tea leaves into an aroma raising machine, and preparing a finished product 3-5 minutes later, wherein the temperature of the aroma raising machine is 90-100 DEG C. The green tea processing process is uniform and complete in water-removing, and the prepared green tea is strong in aroma.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a green tea processing technology. Background technique [0002] Tea is a beverage that people love, and it is also the longest-used traditional beverage raw material. Tea and tea beverages are known as "one of the three major beverages in the world". The ancients once said: "One day without tea will stagnate, and three days without Tea makes people sick." Modern scientific research has confirmed that tea contains biochemical components that are closely related to human health. Tea not only has the functions of refreshing and clearing heart, clearing heat and relieving heat, digesting food and phlegm, removing greasy weight, clearing heart and annoyance, detoxifying and sobering up, promoting body fluid and quenching thirst, reducing fire and improving eyesight. It also has certain pharmacological effects on modern diseases, such as radiation sickness, cardiovascular and ...
