Embodiment 1

[0028] The finished northern Fujian oolong loose tea is used as raw material tea, and the brick-shaped oolong tea is processed into pressed tea. Specific steps are as follows:

[0029] 1) Pour the raw tea into a bamboo sieve and spread it thinly for humidification. Humidification is carried out twice, first humidify to "semi-dry and wet", mix well and pile up, so that the water can be fully absorbed into the tea leaves. After humidification, the tea leaves are placed in a vacuum environment to stand still, and cooling measures are supplemented at the same time to control the temperature of the tea leaves below 18°C. After the water from the first humidification is completely absorbed by the tea leaves, perform the same operation as before and re-humidify once more. The tea leaves are soft and not sticky.

[0030] When humidifying and softening raw tea, it is necessary to control the amount and speed of water addition, not only to ensure that the tea leaves fully absorb water...

Embodiment 2

[0043] The finished product Fenghuang Shanzong (Guangdong Oolong) loose tea is used as the raw material tea, and the disc-shaped oolong tea is processed to press the tea cake tightly. Specific steps are as follows:

[0044] 1) Pour the raw tea into a bamboo sieve and spread it thinly for humidification. Humidification is carried out twice, first humidify to "semi-dry and wet", mix well and pile up, so that the water can be fully absorbed into the tea leaves, and put the humidified tea leaves in a vacuum environment to stand still, supplemented by cooling Measures to control the tea temperature below 20 ℃. After the moisture of the first humidification is completely absorbed by the tea leaves, perform the second humidification. Control the amount and speed of water addition, not only to ensure that the tea leaves fully absorb water to soften, but also to prevent the loss of tea juice.

[0045] Humidification is done by spraying water on the tea leaves, stirring them evenly a...

Embodiment 3

[0050] The finished Taiwan oolong loose tea is used as raw material tea to process steamed bun-shaped oolong tea and press Tuo tea. Specific steps are as follows:

[0051] 1) Pour the raw tea into a bamboo sieve and spread it thinly for humidification. Humidification is carried out twice, first humidify to "semi-dry and wet", mix well, pile up, place in a vacuum environment, and control the temperature of the tea leaves below 35°C. After the moisture of the first humidification is completely absorbed by the tea leaves, perform the second humidification. Control the amount and speed of water addition, not only to ensure that the tea leaves fully absorb water to soften, but also to prevent the loss of tea juice.

[0052] Humidification is accomplished by wetting the tea leaves with atomized water and then leaving them to stand. The weight of raw tea after humidification increases by about 20% to 30%.

[0053] 2) Utilize a mold with a steamed bun-shaped mold cavity to mold th...

Abstract

The invention discloses a preparation method of oolong compressed tea. The method takes finished-product oolong loose tea as raw tea and comprises the following specific steps: (1) wetting and softening the raw tea and carry out mould pressing on the softened raw tea to obtain a pre-set shape; (2) drying the raw tea which is in the pre-set shape formed by the mould pressing to pre-set water content through vacuum dehumidification by using an optical wave heating and / or microwave heating and cooling means, so as to obtain the needed oolong compressed tea. According to the oolong compressed tea, the technical limitations that traditional oolong can only be the loose tea and the fermentation degree of the prepared compressed tea cannot be controlled and the like are broken through, so that the pressure resistance of the tea is improved, the transportation and the carrying of the tea are convenient and the storage condition of the tea is reduced.

Description

technical field [0001] The invention relates to a method for preparing pressed oolong tea and pressed pressed oolong tea prepared by the method. Background technique [0002] Dark tea, represented by Puer tea and Liubao tea, is traditionally made into pressed tea. This is because dark tea is a post-fermented tea, and the "stacking" effect caused by pressing together and the growth of probiotics not only There is no harm, and it also helps the biochemical reactions in the tea leaves, and helps the post-fermentation of the tea leaves. Moreover, making pressed tea is also convenient for the storage of tea leaves, which is beneficial to the long-term natural fermentation of tea leaves in the later stage. Oolong tea is semi-fermented tea, and its fermentation is completed during the production process. If it is made into pressed tea, it will not be able to complete the various processes in the production process, and the degree of fermentation of the tea leaves cannot be control...
