Problems solved by technology

[0003] Quhao-shaped black tea is currently sold in the market, such as Jinluo black tea, Qimen Xiangluo, etc. The product has a beautiful appearance and a reddish-brown color, but its moisture is relatively poor, its taste is generally green, and its aroma is old. Therefore, on the premise of maintaining the beautiful appearance of Quhao-shaped black tea, how to further improve the color and luster and inner quality flavor, and promote the double excellence of Quhao black tea's internal and external quality has become a problem of great concern to researchers and manufacturers.

Embodiment 1

[0016] Example 1 A kind of processing method of koji-shaped black tea

[0017] The raw material of fresh leaves used is: 50 kg of fresh leaves of Fuding Dabai variety tea mainly with 1 bud 1 leaf - 1 bud 2 leaves first developed.

[0018] The specific implementation is as follows:

[0019] (1) Place the mat with fresh leaves in the sun for 20 minutes at about 8:00 in the morning, turn it once during the period, then move it to a cool place for 30 minutes; then place it in the sun again for 20 minutes, remove To a cool place for 30 minutes, repeat this 4 times until the moisture content of fresh leaves is around 66-68%.

[0020] (2) Put the sun-dried green leaves in a withering room at 22°C-24°C / RH80-90% (using the green air-handling unit produced by Yuyao Yao Jiangyuan Tea Machine Co., Ltd. to adjust the ambient temperature and humidity) for airing, until The moisture content is 62%-64%.

[0021] (3) Put the finished product into the kneading machine (6CR-35 kneading machi...

Embodiment 2

[0026] Example 2 A kind of processing method of koji-shaped black tea

[0027] The raw material of fresh leaves used is: 50 kg of fresh leaves of Yingshuang variety tea with 1 bud and 1 leaf - 1 bud and 2 leaves for the first development.

[0028] The specific implementation is as follows:

[0029] (1) Place the mat with fresh leaves in the sun for 30 minutes at around 5 p.m., turn it once during the period, then move it to a cool place for 30 minutes; then place it in the sun again for 30 minutes, remove To a cool place for 30 minutes, repeat this 3 times until the moisture content of fresh leaves is around 66-68%.

[0030] (2) Put the sun-dried green leaves in a withering room at 22°C-24°C / RH80-90% (using the green air-handling unit produced by Yuyao Yao Jiangyuan Tea Machine Co., Ltd. to adjust the ambient temperature and humidity) for airing, until The moisture content is 62%-64%.

[0031] (3) Put the finished product into the kneading machine (6CR-35 kneading machine...

Embodiment 3

[0036] Example 3 Sensory evaluation of Quhao black tea made from two raw materials

[0037] The Quhao-shaped black tea prepared in Example 1 and Example 2 was subjected to sensory evaluation, and compared with the Quhao-shaped black tea prepared by the existing method, the results are shown in Table 1.

[0038]

[0039] It can be seen from the review results of the tea samples that the present invention achieves a better flavor endoquality through the organic integration and integrated innovation of sun-drying technology / aerobic fermentation / shaping of bent hair / cold wind color protection / manual assisted forming technology. At the same time, it can also make the appearance of the finished tea with a unique shape, which is obviously better than the tea samples made by the existing method.

Abstract

The invention provides a processing method for curved black tea. The processing method comprises the following steps of carrying out sunning treatment on fresh leaves, naturally withering and lightly rolling; then introducing oxygen and fermenting; then drying a product to be with a certain water content by using a drying machine; then putting the product on a curve frying machine to be shaped; and finally, putting the product on drying equipment to be shaped by handwork and drying. According to the processing method provided by the invention, foundations are laid for flavor quality by processes of sunning, withering, introducing the oxygen, fermenting and the like; foundations are laid for appearance quality by processes of shaping by curves, protecting the color by cold air, manually assisting and the like; finally, the specially-produced curved black tea which is beautiful in appearance, high in color and aroma and mellow in taste is obtained.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and relates to black tea production technology, in particular to a processing method of koji-shaped black tea. Background technique [0002] There are three main types of black tea: Souchong black tea, Gongfu black tea and red crushed tea. In terms of shape, red crushed tea is in the shape of shredded tea, while traditional Souchong black tea and Gongfu black tea are both in strip shape. As far as the production technology is concerned, the current black tea production process is mainly fresh leaves-withering-rolling-fermentation-drying. According to the different rolling processes, red crushed tea is obviously different from the other two. Technology, using specific equipment to cut fresh leaves into pieces, and then carry out fermentation and drying operations; Souchong black tea and Gongfu black tea are both kneaded and shaped by kneading machines. The main difference lies in the diffe...
