Problems solved by technology

At present, there are three main methods of black tea withering, namely blast withering, sunlight withering, and freezing withering. Blast withering and solar withering have a high rate of nutrient loss, but the aroma is better maintained. The processed black tea has a high and long-lasting aroma. The rate is low, but the aroma loss is high, and the aroma of the processed black tea is relatively light

Embodiment 1

[0014] Embodiment 1, a kind of black tea withering method, specifically:

[0015] (1) Picking fresh tea leaves with one bud and two leaves as raw materials for withering;

[0016] (2) Spread the fresh original leaves on the withering rack with a layer thickness of 1 cm, and send the fresh original leaves into the freezer for freezing. The temperature in the freezer is -5°C, and the freezing time is 30 minutes;

[0017] (3) Send the fresh raw leaves obtained by freezing into the evaporation chamber for instant evaporation treatment, the instant evaporation temperature is 200°C, and the instant evaporation time is 1 second;

[0018] (4) Spray a layer of wort evenly on the surface of the fresh original leaves obtained by instant evaporation, place at 26°C for 40 minutes, and then knead.

Embodiment 2

[0019] Embodiment 2, a kind of black tea withering method, specifically:

[0020] (1) Picking fresh tea leaves with one bud and two leaves as raw materials for withering;

[0021] (2) Spread the fresh original leaves on the withering rack with a layer thickness of 1.2 cm, and send the fresh original leaves into the freezer for freezing. The temperature in the freezer is -6°C, and the freezing time is 32 minutes;

[0022] (3) Send the fresh raw leaves obtained by freezing into the evaporation chamber for instant evaporation treatment, the instant evaporation temperature is 204°C, and the instant evaporation time is 1 second;

[0023] (4) Spray a layer of wort evenly on the surface of the fresh original leaves obtained by instant evaporation, place at 26°C for 42 minutes, and then knead.

Embodiment 3

[0024] Embodiment 3, a kind of black tea withering method, specifically:

[0025] (1) Picking fresh tea leaves with one bud and two leaves as raw materials for withering;

[0026] (2) Spread the fresh original leaves on the withering rack with a layer thickness of 1.3 cm, and send the fresh original leaves into the freezer for freezing. The temperature in the freezer is -7°C, and the freezing time is 35 minutes;

[0027] (3) Send the frozen fresh original leaves into the evaporation chamber for instant evaporation treatment, the instant evaporation temperature is 210°C, and the instant evaporation time is 1.1 seconds;

[0028] (4) Spray a layer of wort evenly on the surface of the fresh original leaves obtained by instant evaporation, place at 27°C for 45 minutes, and then knead.

Abstract

The invention belongs to the technical field of tea processing, and specifically relates to a black tea withering method. Fresh tea leaves with one bud and two leaves are picked as raw materials for withering. ‑8°C, the freezing time is 30‑38 minutes, and the fresh raw leaves obtained by freezing are sent to the evaporation chamber for instant evaporation treatment. The instant evaporation temperature is 200‑220 °C, and the instant evaporation time is 1‑1.2 seconds. Spray a layer of wort evenly on the surface of fresh original leaves, place it at 26-28°C for 40-50 minutes, and then knead. Nutrient loss also ensures low aroma loss, so that the finally obtained black tea is not only rich in influence, but also has the advantages of high and lasting aroma.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and in particular relates to a black tea withering method. Background technique [0002] Withering is the process of thinly spreading fresh tea leaves on the withering curtain (trough) to make them disperse water, changing from brittle and hard to withered and withered. The first purpose of withering is to evaporate part of the water, reduce the tension of tea cells, and make the leaves The stalk changes from brittle to soft, which increases the toughness of the buds and leaves, and is easy to knead into strips; secondly, due to the loss of water, a series of chemical changes in the substances contained in the tea shoots are caused to form the specific quality of tea color, aroma and taste. , laying the foundation for material change. At present, there are three main methods of black tea withering, namely blast withering, sunlight withering, and freezing withering. Blast withering and sol...
