Embodiment 1

[0012] A method for drying black tea, specifically:

[0013] (1) Put the tea leaves in the dryer with a thickness of 8 cm;

[0014] (2) One drying: control the temperature at 130°C for 10 minutes;

[0015] (3) Second drying: control the temperature at 120°C for 10 minutes;

[0016] (4) Then take the tea out of the dryer and let it cool for 30 minutes;

[0017] (5) Three times of drying: put the tea into the dryer again to dry at a temperature of 80°C for 8 minutes.

[0018] Example 1 best effect.

Embodiment 2

[0020] A method for drying black tea, specifically:

[0021] (1) Put the tea leaves in the dryer and spread them to a thickness of 10 cm;

[0022] (2) One drying: control the temperature at 130°C for 15 minutes;

[0023] (3) Second drying: control the temperature at 120°C for 15 minutes;

[0024] (4) Then take the tea out of the dryer and let it cool for 40 minutes;

Abstract

The present invention proposes a drying method for black tea, specifically: (1) placing the tea leaves in a drying machine with a thickness of 8-10 cm; -15 minutes; (3) Second drying: control the temperature at 120°C for 10-15 minutes; (4) Then take the tea out of the dryer and let it cool for 30-40 minutes; (5) Three drying : Put the tea leaves into the dryer again to dry at a temperature of 80°C for 6-10 minutes. In the present invention, the first drying, high temperature and fast drying, can quickly eliminate the enzymatic oxidation, the lower the temperature, the longer the time, the greater the damage to the quality; the second drying, the temperature is slightly lower, quickly eliminating the effect of heat and humidity, Humidity and heat cause the color to darken, the taste to fade, and the aroma to be dull; after the second drying, spread it to cool, so that the tea leaves with uneven moisture in the drying process will rehydrate each other. Three times of drying, low temperature and slow drying, avoiding old fire, which is conducive to the formation of black tea aroma. The drying method of the invention is even and sufficient, and the tea leaves have sufficient fragrance.

Description

technical field [0001] The invention relates to a method for drying black tea. Background technique [0002] The traditional black tea drying method adopts two drying processes of the dryer, the main fire and the full fire. The main fire controls the temperature at 110°C-120°C for 10 minutes; the full fire is 85°C-95°C for 15 minutes. Although this drying method takes a short time, the drying is uneven and insufficient, and the aroma of the tea leaves is insufficient. Contents of the invention [0003] The invention proposes a drying method for black tea, and the technical problem to be solved is mainly to solve the problems of uneven and insufficient drying and insufficient aroma of tea leaves. [0004] For this reason, the technical scheme of the present invention is: a kind of drying method of black tea, specifically: [0005] (1) Put the tea leaves in the dryer and spread out the thickness of 8-10 cm; [0006] (2) One drying: control the temperature at 130°C for 10-...
