Problems solved by technology

[0003] As the current finished oolong tea loose tea is usually made directly from the fresh leaves of the tea leaves, and the fresh leaves of the tea leaves not only have dust, insect eggs, bird and animal feces, pesticide residues and other pollutants attached to the surface, but also remain inside the leaves absorbed by the tea leaves. Therefore, these pollutants will enter the finished loose tea with the processing of fresh leaves, and finally enter the tea soup, endangering the health of drinkers

Embodiment 1

[0035] Using Fujian Anxi oolong tea finished loose tea as raw material tea to prepare oolong tea pressed tea, the specific steps are as follows:

[0036] 1) First, pour the finished loose tea or the finished loose tea into the bamboo sieve to spread thin, and spray solvent water for humidification;

[0037] In order to avoid excessive spraying of solvent water and cause loss of tea juice, the solvent water is sprayed several times. After each spraying, the water is mixed well and piled up so that the water is fully absorbed into the tea leaves until the tea leaves are saturated with water. After each water spraying, move the tea leaves to a vacuum environment in time, and control the temperature of the tea leaves to ≤25°C;

[0038] In addition to spraying solvent water for tea humidification, it can also be completed by soaking tea leaves with atomized solvent water and then standing still;

[0039] Then, place the humidified tea leaves in a vacuum environment in time, and dry ...

Embodiment 2

[0054] The finished loose tea of ​​Wuyi rock tea is used as raw material tea to prepare oolong tea pressed tea, and the specific steps are as follows:

[0055] 1) First, put the finished loose tea into a vacuum environment, spray solvent water in the vacuum environment or soak the tea leaves with atomized solvent water and let it stand, while controlling the temperature of the tea leaves to ≤30°C until the tea leaves are saturated with water;

[0056] Then, the humidified tea leaves are placed in a vacuum environment, and the tea leaves are dried to a moisture content of ≤10% by applying microwaves;

[0057] During the drying process, adjust the vacuum degree of the vacuum environment and the microwave power to control the temperature of the tea leaves to ≤70°C;

[0058] 2) Step 1) was repeated twice. The solvent water used in the first humidification is composed of pure water with added bianzyme, and the amount of bianzyme added is: 100 liters of pure water is added with 2 g...

Embodiment 3

[0064] The finished loose tea of ​​Guangdong oolong tea is used as raw material tea to prepare oolong tea pressed tea, and the specific steps are as follows:

[0065] 1) First, put the finished loose tea or finished loose tea into a vacuum environment, spray solvent water in the vacuum environment or use atomized solvent water to moisten the tea leaves and let it stand, while controlling the temperature of the tea leaves to ≤35°C;

[0066] Then, the humidified tea leaves are placed in a vacuum environment, and the tea leaves are dried to a moisture content of ≤10% by applying microwaves;

[0067] During the drying process, adjust the vacuum degree of the vacuum environment and the microwave power to control the temperature of the tea leaves to ≤80°C;

[0068] 2) Step 1) was repeated three times. The solvent water used in the first and second humidifications is composed of purified water with added bianzyme, the amount of bianzyme added is: 0.5 grams of bianzyme dry powder add...

Abstract

The invention discloses a preparation method of compressed oolong tea. The method is characterized by using finished loose oolong tea as the raw tea, and during preparation, firstly carrying out purification treatment on the raw tea and then preparing the purified raw tea into 20-5000g of compressed oolong tea, wherein the specific purification treatment steps are as follows: 1) firstly wetting the tea by utilizing a solvent-water until the tea absorbs water to become saturated; then putting the wetted tea in the vacuum environment and drying the tea by applying microwave until the water content is not more than 10%; 2) repeating the step 1) multiple times; 3) selecting the tea by wind and sieving the tea, thus completing purification treatment of the raw tea. The preparation method has the beneficial effects that thorough purification of the inside and outside of the raw tea is achieved under the premise of not damaging the existing aroma, taste and quality of the tea, thus ensuring the hygiene and safety of the finally prepared compressed oolong tea.

Description

technical field [0001] The invention relates to a preparation method of pressed oolong tea. Background technique [0002] The applicant had previously applied for a method for preparing pressed oolong tea. In this method, the finished oolong tea loose tea was used as the raw material tea, and the required 15-5000 gram blocks were obtained through the processes of humidifying and softening the raw material tea, molding, and drying. Shaped oolong tea squeezed tea. [0003] As the current finished oolong tea loose tea is usually made directly from the fresh leaves of the tea leaves, and the fresh leaves of the tea leaves not only have dust, insect eggs, bird and animal feces, pesticide residues and other pollutants attached to the surface, but also remain inside the leaves absorbed by the tea leaves. Therefore, these pollutants will enter the finished loose tea as the fresh leaves are processed, and finally enter the tea soup, endangering the health of drinkers. Contents of ...
