Description

A kind of preparation method of Radix Isatidis black tea

Technical field

The present invention relates to a kind of preparation method of Radix Isatidis black tea.

Background technology

Radix Isatidis (conventional another name: indigo-blue, indigo root, manyflower glorybower root) be a kind of Chinese medicine.For the dry root of cruciferae isatis, usually excavate in the fall, can be used as medicine after the process of preparing Chinese medicine, all produce all over China, especially there is the effect of prevention, treatment flu.

Also there is no a kind of isatis root tea adopting Radix Isatidis rhizome and tealeaves to mix in the prior art.

Summary of the invention

In view of the isatis root tea also not adopting Radix Isatidis rhizome and tealeaves to mix at present, the invention provides a kind of preparation method of the Radix Isatidis black tea adopting Radix Isatidis rhizome and tealeaves to mix.

The technical scheme that the present invention solves its technical problem is: a kind of preparation method of Radix Isatidis black tea, comprises the following steps:

1.. select materials: win Radix Isatidis rhizome and two leaves fresh tea passes wholeheartedly;

2.. mixing stand is blue or green: Radix Isatidis rhizome and fresh tea passes are evenly mixed 1:1.5 ~ 4 in mass ratio, be spread out on bamboo plaque, in constant temperature dehumidifier room in 18 DEG C ~ 25 DEG C, humidity 35% ~ 40% time stand green grass or young crops 14 hours, within every two hours, turns over leaf 1 time;

3.. synchronously knead: by blue or green for stand complete after Radix Isatidis rhizome and the mixture of tealeaves at kneading machine

On knead 100 minutes;

4.. fermentation: the tealeaves after kneading, Radix Isatidis rhizome separate bulk also by hand on bamboo plaque

Shake up, be then placed in ferment at constant temperature room, 18 DEG C ~ 22 DEG C, keep more than 95% humidity, ferment 4 ~ 5 hours;

5.. syllogic is dried: first dries 15min at 110 DEG C ~ 120 DEG C; Second dries 20min at 75 DEG C ~ 85 DEG C; Third time dries 20min at 60 DEG C ~ 70 DEG C;

Oven dry for the first time and for the second time interval 30min between oven dry, second time oven dry and for the third time interval 30min between oven dry;

6.. screen: dry after terminating and naturally cool on bamboo plaque, sieve with bamboo and carry out screen and canned.

Beneficial effect of the present invention is: make on experiential basis at summary folk tradition and improved, set up a set of not affect by environmental change, the complete process flow of health protection tea can be produced for a long time at Radix Isatidis growing period, open health protection tea product new varieties, preventing cold tool is had certain effect.
