Problems solved by technology

However, the production of Shantou tea with strong tea flavor is low and expensive, and the price of tea has been rising year after year. The market supply is seriously insufficient, which affects the awareness and expansion of consumers.
The origin of raw Pu'er tea is not only limited to high-altitude areas, but also the variety is limited to large-leaf species in Yunnan, which severely limits the popularization and variety of raw Pu'er tea processing.
There is no relevant report on the flavor processing of raw Pu-erh tea in the current research

Embodiment 1

[0033] This example provides a method for preparing raw Pu-erh tea using low-altitude tea raw materials. The variety of tea raw materials used is Yinghong No. 9, and the experiment time is April 13-14, 2017. The specific method includes the following steps:

[0034] (1) Withering: using one bud, two leaves and three leaves of Yinghong No. 9 tea tree and opposite pod leaves of the same tenderness as fresh tea leaf raw materials, the fresh tea leaf raw materials are withered until the water content is 76.2%, and material A is obtained.

[0035] (2) The first greening: use 901 gas greening machine to carry out greening treatment on material A, adjust the number of revolutions of the greening machine to 3 rpm, the amount of leaves thrown is 10, 35 kg, and the temperature of greening is 150-250 °C, The killing time is 15-90 minutes, until the bud color pekoe is revealed and the leaves are slightly black, then the machine is removed to obtain the material B.

[0036] (3) The first s...

Embodiment 2

[0046] This example provides a method for preparing raw Pu-erh tea using low-altitude tea raw materials. The variety of tea raw materials used is Yinghong No. 9, and the experiment time is April 15-16, 2017. The specific method includes the following steps:

[0047] (1) withering: with embodiment 1.

[0048] (2) First time greening: use 901 gas greening machine to carry out greening treatment on material A, adjust the number of revolutions of the greening machine to 3 rpm or 10 rpm, and the amount of leaves to be thrown is 35 kg each, that is, to the tea raw material Until it falls out automatically, the temperature for finishing is 200° C., the time for finishing is 60 minutes, and material B is obtained.

[0049] (3) pile for the first time: with embodiment 1.

[0050] (4) The second finishing: put all the material C into the 901 gas cleaning machine, carry out the finishing treatment on the material C, adjust the number of rotations of the cleaning machine to 3 rpm or 10 r...

Embodiment 3

[0058] This example provides a method for preparing raw Pu-erh tea using low-altitude tea raw materials. The variety of tea raw materials used is Yinghong No. 9, and the experiment time is April 15-16, 2017. The specific method includes the following steps:

[0059] (1) withering: with embodiment 1.

[0060] (2) Finishing: Adopt 901 gas-fired greening machine to carry out finishing process to material A, adjust the number of revolutions of the fixing machine to be 3 revolutions per minute, and the amount of leaf throwing is 35 kg, that is, until the tea raw materials fall out automatically, the temperature of finishing is 200°C, the time for finishing is 60 or 100 minutes, get off the machine, and obtain material B.

[0061] (3) Wheat heap: Pour material B into a cloth bag or square towel and wrap it in a pile for 30 minutes immediately after getting off the machine to obtain material C. The water content of material C is 58% and 30% respectively.

[0062] (4) Kneading: Pour ...

Abstract

The invention relates to a method for preparing raw Pu'er tea from tea raw materials growing at low altitude. The method comprises withering, deactivation of enzymes, pile fermentation, re-deactivation of enzymes, re-fermentation of a pile, rolling and drying in the sun. According to the method, a temperature in deactivation of enzymes is in a range of 170-230 DEG C, total time of deactivation of enzymes is 70-130min, the rotation number of a machine of deactivation of enzymes is 2-4 r / min and the pile fermentation process is carried out at a high temperature. The method utilizes different pieces of tea or tea picked in different reasons as a raw material. The products in different batches have the same and stable quality the same to that of Yunnan raw Pu'er tea growing at high altitude. The method widens a Pu'er tea raw material resource, greatly improves a raw Pu'er tea yield and reduces a production cost.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a method for preparing Pu'er raw tea from low-altitude tea raw materials. Background technique [0002] Raw Pu-erh tea is praised by consumers for its unique tea flavor, especially the tea from several hills in Yunnan. However, the production of Shantou tea with strong tea flavor is low, the price is high, and the price of tea has been rising year after year. The market supply is seriously insufficient, which affects the awareness and expansion of consumer groups. The origin of raw Pu-erh tea is not only limited to high-altitude areas, but also the variety is limited to large-leaf varieties in Yunnan, which severely limits the popularization and variety of Pu-erh raw tea processing. There is no relevant report on the flavor processing of raw Pu-erh tea in the current research. [0003] However, there are large areas of tea gardens in low-altitude areas across the country...
