Example Embodiment
[0040] Example 1
[0041] Use Lapsang Souchong black tea primary processed tea (mao tea) or refined tea as raw materials to process black tea teabags.
[0042] The processing steps are as follows:
[0043] 1. Purification:
[0044] 1.1. First, pour the tea into a bamboo sieve to thin, spray solvent water for humidification, until the tea is saturated with water.
[0045] In order to avoid excessive spraying of solvent water, resulting in the loss of tea juice, spray the solvent water several times, and mix well after each spray, so that the water can be fully absorbed into the tea. After each spraying, move the tea leaves to a vacuum environment and let them stand, while controlling the temperature of the tea leaves to be ≤35℃.
[0046] In addition to spraying solvent water, the humidification of tea leaves can also be completed by soaking the tea leaves with atomized solvent water.
[0047] Then, the humidified tea leaves are placed in a vacuum environment in time, and the tea leaves a...
Example Embodiment
[0067] Example 2
[0068] Use Qimen black tea primary processed tea (maocha) or refined tea as raw materials to process black tea teabags.
[0069] The processing steps are as follows:
[0070] 1. Purification:
[0071] 1.1. First, put the tea leaves in a vacuum environment, spray solvent water in the vacuum environment or use atomized solvent water to infiltrate the tea leaves and let them stand, while controlling the temperature of the tea leaves ≤ 30°C until the tea leaves are saturated with water.
[0072] Then, the humidified tea leaves are placed in a vacuum environment, and the tea leaves are dried to a moisture content ≤ 10% by applying microwaves.
[0073] During the drying process, the temperature of the tea leaves is controlled to be ≤70°C by adjusting the vacuum degree and microwave power of the vacuum environment.
[0074] 1.2. Repeat step 1.1 twice. The solvent water used for the first humidification is composed of purified water added with Biazyme. The amount of Biazyme a...

[0082] Example 3
[0083] Use Dianhong Kungfu black tea as raw materials to process black tea teabags (mao tea) or refined tea.
[0084] The processing steps are as follows:
[0085] 1. Purification:
[0086] 1.1. First, put the tea leaves 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℃.
[0087] Then, the humidified tea leaves are placed in a vacuum environment, and the tea leaves are dried to a moisture content ≤ 10% by applying microwaves.
[0088] During the drying process, the temperature of the tea leaves is controlled to be ≤60°C by adjusting the vacuum degree and microwave power of the vacuum environment.
[0089] 1.2. Repeat step 1.1 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 and 0.5 g of...
