Embodiment 1
[0017] A kind of preparation method of black tea, concrete steps are as follows:
[0018] (1) Withering, put the tea leaves in the withering machine, spread the tea leaves to a thickness of 40 cm, first wither with cold air for 3 hours, then wither with hot air for 2 hours, the temperature of the hot air is 35°C, stop for 1 hour, and then Hot air withering for 2 hours, hot air temperature 35°C; throughout the whole withering process, turn the tea leaves every 15 minutes;
[0019] (2) Kneading, using a kneading machine to knead;
[0020] (3) Fermentation, using a fully automatic fermentation machine for fermentation;
[0021] (4) Drying, put the tea leaves in the dryer, and spread out the thickness of 8-10 cm; one drying, control the temperature at 130°C, and the time is 10 minutes; the second drying, control the temperature at 120°C, and the time is 10 minutes Minutes; then take the tea leaves out of the dryer and let them cool for 30 minutes; dry them three times, put the t...

Abstract
The invention provides a black tea manufacturing method which comprises the following special steps: (1) wilting: tea leaves are put in a wilting machine for wilting, the spreading thickness of the tea leaves is 40-60 cm, the tea leaves are first wilted for 2-3 h by cold air and then wilted for 1-2 h by hot air, the hot air temperature is 35-40 DEG C, the wilting machine is stopped for 1 h, the tea leaves are wilted for 1-2 h by hot air again, the hot air temperature is 35-40 DEG C, and during the wilting process, the tea leaves are turned every 15 minutes; (2) twisting: a twisting machine is adopted for twisting the tea leaves; (3) fermenting: a full-automatic fermenting machine is adopted for fermenting; (4) drying: the tea leaves are put in a drying machine, the spreading thickness is 8-10 cm, the tea leaves are dried for 10-15 min for the first time at the control temperature of 130 DEG C, then are dried for 10-15 min for the second time at the control temperature of 80 DEG C, next, the tea leaves are taken out from the drying machine, and are cooled for 30-40 min after being spread, and the tea leaves are put in the drying machine again and then dried for 6-10 min for the third time at the control temperature of 80 DEG C. The black tea manufacturing method can reduce the manufacturing time of black tea considerably, and improves the black tea quality.
Description
technical field [0001] The invention relates to a method for making black tea. Background technique [0002] The traditional method of making black tea is withering, rolling, fermenting and drying. [0003] Withering generally adopts indoor natural withering, at room temperature 20-24 ℃, relative humidity 60%-70%, withering for about 18 hours, adjust the temperature and humidity by opening and closing doors and windows; [0004] Kneading adopts 30,50 kneading machine; fermentation adopts fermentation room method; [0005] Drying, use the dryer to dry on the first heat and the second heat, the first heat is 110°C-120°C for 10 minutes, and the full heat is 85°C-95°C for 15 minutes. [0006] Existing problems: the production of traditional black tea takes a long time, and the withering is uneven and insufficient, and the drying is uneven and insufficient, and the quality of the produced black tea is low. Contents of the invention [0007] In order to reduce the production ...
