Example Embodiment

[0032] Example 1

[0033] Purification object: Lapsang Souchong black tea Maocha or finished loose tea

[0034] The purification steps are as follows:

[0035] 1) First, pour the Maocha or the finished loose tea into a bamboo sieve to dilute, and spray solvent water for humidification;

[0036] In order to avoid excessive spraying of solvent water, resulting in the loss of tea juice, spray the solvent water several times. After each spray, mix and pile up so that the water is fully absorbed into the tea until the tea is saturated with water. After each spraying, move the tea leaves to a vacuum environment to stand still, and control the temperature of the tea leaves to be ≤35℃;

[0037] In addition to spraying solvent water, the humidification of tea leaves can also be completed by soaking the tea leaves with atomized solvent water;

[0038] Then, put the humidified tea leaves in a vacuum environment in time, and dry the tea leaves to a moisture content ≤10% by applying microwaves;

[0049] Example 2

[0050] Purification object: Qimen black tea Maocha or finished loose tea

[0051] The purification steps are as follows:

[0052] 1) First, put the wool tea or the finished loose tea in a vacuum environment, spray solvent water in the vacuum environment or use atomized solvent water to soak the tea leaves and let them stand, while controlling the temperature of the tea leaves ≤ 30 ℃, until the tea is saturated with water;

[0053] Then, place the humidified tea leaves in a vacuum environment, and apply microwaves to dry the tea leaves to a moisture content of ≤10%;

[0054] During the drying process, by adjusting the vacuum degree and microwave power of the vacuum environment, the tea temperature is controlled to be ≤70℃;

[0055] 2) Step 1) is repeated twice. The solvent water used for the first humidification is composed of purified water added with Biazyme. The amount of Biazyme added is: 100 liters of purified water and 2 grams of Biazyme dry powder; for the seco...

[0059] Purification object: Dianhong Kungfu black tea Maocha or finished loose tea

[0060] The purification steps are as follows:

[0061] 1) First, put the wool tea or the finished loose tea in a vacuum environment, spray solvent water in the vacuum environment or use atomized solvent water to moisten the tea leaves and let them stand, while controlling the temperature of the tea leaves ≤28℃;

[0062] Then, place the humidified tea leaves in a vacuum environment, and apply microwaves to dry the tea leaves to a moisture content of ≤10%;

[0063] During the drying process, by adjusting the vacuum degree and microwave power of the vacuum environment, the temperature of the tea leaves is controlled to be ≤60°C;

[0064] 2) Step 1) is repeated four times. The solvent water used for the first and second humidification is composed of purified water with Biazyme. The addition amount of Biazyme is: 100 liters of purified water is added to 0.5 g Subenzyme dry powder; for the...

Abstract

The invention discloses a black tea purification method. The black tea purification method is used for conducting purification treatment on primary black tea or fine black tea and comprises the specific steps that 1, tea is wetted by using solvent water till the tea absorbing the water is saturated, the temperature of the tea in the wetting process is controlled to be smaller than or equal to 35 DEG C, then the wetted tea is timely put in a vacuum environment and is dried by applying microwaves till the moisture content is smaller than or equal to 10%, and the temperature of the tea is controlled to be smaller than or equal to 80 DEG C; 2, the step 1 is repeated for multiple times; 3, air separation and screening are conducted on the tea; 4, the tea is baked till the moisture content is smaller than or equal to 6%, and required purified black tea is obtained. The black tea purification method achieves thorough purification of the inside and outside of the tea on the premise that the aroma, taste and quality of the tea are not destroyed and ensures that the tea is hygienic and safe.

Description

technical field [0001] The invention relates to a method for purifying black tea, in particular to a method for purifying raw black tea and finished black tea loose tea. Background technique [0002] After the fresh black tea leaves are picked, they need to be processed into raw tea through primary processes such as withering, rolling, fermentation, and drying, and then processed into finished black tea loose tea (hereinafter referred to as fine tea) through picking, winnowing, refire and other processes. . [0003] Since the fresh leaves are directly processed after picking, the tea leaves are inevitably covered with pollutants such as dust, insect eggs, bird and animal feces, and pesticide residues. In particular, pesticide residues not only adhere to the surface of the tea, but are also partially absorbed by the tea. Although people mostly rinse black tea with boiling water before drinking it, since black tea raw tea and finished black tea loose tea are both in the shap...
