Embodiment 1

[0024] The preparation technology of embodiment 1 fermented tea of ​​the present invention

[0025] A preparation process for fermented tea, comprising the following steps:

[0026] 1) Picking fresh leaves: Manually pick fresh and tender tea leaves without pests and diseases, and place the fresh leaves in a clean bamboo basket in a cool and ventilated place;

[0027] 2) Withering: put the fresh leaves in a temperature-controlled room to wither, the leaves are soft and the water loss rate reaches 30% as appropriate; the withering ambient temperature is 10° C., the ambient humidity is 20%, and the withering time is 12 hours.

[0028] 3) Kneading: Select the corresponding type of kneading machine according to the batch of fresh tea leaves. The kneading pressure should be light and heavy, and the time should be controlled within 1 hour.

[0029] 4) Fermentation: Put the fresh leaves finished in the rolling process on a drying rack with a bamboo plaque and place them in a temperat...

Embodiment 2

[0035] A preparation process for fermented tea, comprising the following steps:

[0036] 1) Picking fresh leaves: Manually pick fresh and tender tea leaves without pests and diseases, and place the fresh leaves in a clean bamboo basket in a cool and ventilated place;

[0037] 2) Withering: place the fresh leaves in a temperature-controlled room to wither. The leaf quality is soft and the water loss rate reaches 30%.

[0038] 3) Kneading: Select the corresponding type of kneading machine according to the batch of fresh tea leaves. The kneading pressure should be light and heavy, and the time should be controlled within 1.5 hours.

Abstract

The invention provides a fermented tea preparing process. The process comprises the steps of fresh leaf picking; deterioration; rolling; fermentation, wherein rolled fresh leaves are placed in bamboo baskets, then on an airing frame and finally in a temperature control chamber to be fermented till over 90% leaves become red; first drying, wherein properly fermented leaves are taken out and then put into a dryer instantly till leaves are tightly shrunk and water loss ratio reaches 70%; drying, wherein leaves subjected to first drying are cooled and then placed in the temperature control chamber to be dried till water loss ratio reaches 85% or more; re-drying and cooling, wherein dried leaves are put into the dryer to be dried again till water loss ratio reaches 90% or more, and then taken out of the dryer and placed in the temperature control chamber to be spread so as to be cooled; bagging and storage, wherein raw tea cooled to room temperature is bagged and stored at a shady and cool position, preferably in a fresh-keeping storehouse with temperature set to be 0-5 DEG C. The process is wide in application range and low in cost, and all materials are environmentally friendly and recyclable. The number of adopted processing devices is small, and preparation and operation are easy.
