Problems solved by technology

These needle-bud-shaped famous teas are all made of single buds, and the requirements for raw materials are very strict, and no leaves can be mixed. However, with the sharp increase in picking costs, the quality of picking is declining year by year. The phenomenon of raw materials being mixed with leaves is very common. In the traditional processing process, it takes a lot of manual rubbing and rubbing to remove the leaves. The cost is high and the efficiency is extremely low. There is an urgent need for a hygienic, efficient and low-cost method to replace manual rubbing. Leaf process for continuous production

Embodiment 1

[0027] A kind of fresh leaf raw material used for the processing of needle-bud-shaped famous and high-quality green tea is: 50 kilograms of single-bud raw material fresh leaves entraining a small amount of one bud and one leaf.

[0028] The specific implementation is as follows:

[0029] (1) Spread the fresh leaves on a multi-layer stainless steel mesh rack with a thickness of no more than 2 cm, and place them in a temperature-controlled and humidity-controlled booth until the moisture content of the fresh leaves is 69%;

[0030] (2) Put green leaves obtained in step (1) on the YJY-EM-80-A electromagnetic drum fixer produced by Yuyao Yao Jiangyuan Tea Machine Co., Ltd. for fixation treatment, fixation temperature: first section 260°C, second section 220°C, 200°C in the third stage, 160s for greening, until the water content is 58%, at this time, the tea leaves are dry on the outside and wet on the inside;

[0031] (3) Put the green leaves obtained in step (2) directly into th...

Embodiment 2

[0040] A kind of fresh leaf raw material used for the processing of needle-bud-shaped famous and high-quality green tea is: 50 kilograms of single-bud raw material fresh leaves entraining a small amount of one bud and one leaf.

[0041] The specific implementation is as follows:

[0042] (1) Spread the fresh leaves on a multi-layer stainless steel mesh rack with a thickness of no more than 2 cm, and place them in a temperature-controlled and humidity-controlled booth until the moisture content of the fresh leaves is 68%;

[0043] (2) Put green leaves obtained in step (1) on the YJY-EM-80-A electromagnetic drum fixer produced by Yuyao Yao Jiangyuan Tea Machine Co., Ltd. for fixation treatment, fixation temperature: first section 250°C, second section 210°C, 180°C in the third stage, 180s for greening, until the water content is 55%, at this time, the tea leaves are dry on the outside and wet on the inside;

[0044] (3) Put the green leaves obtained in step (2) directly into th...

Embodiment 3

[0053] A kind of fresh leaf raw material used for the processing of needle-bud-shaped famous and high-quality green tea is: 50 kilograms of single-bud raw material fresh leaves entraining a small amount of one bud and one leaf.

[0054] The specific implementation is as follows:

[0055] (1) Spread the fresh leaves on a multi-layer stainless steel mesh rack with a thickness of no more than 2 cm, and place them in a temperature-controlled and humidity-controlled booth until the moisture content of the fresh leaves is 70%;

[0056] (2) Put green leaves obtained in step (1) on the YJY-EM-80-A electromagnetic drum fixer produced by Yuyao Yao Jiangyuan Tea Machine Co., Ltd. for fixation treatment, fixation temperature: first section 255°C, second section 210°C, 190°C in the third stage, 150s for curing time, until the water content is 60%, at this time, the tea leaves are dry on the outside and wet on the inside;

[0057] (3) Put the green leaves obtained in step (2) directly into...

Abstract

The invention discloses a full-automatic method for processing leaf-removed needle bud-shaped tea and belongs to the technical field of tea processing. The method comprises the following steps: tedding fresh leaves, deactivating enzyme, roasting, blowing tea pieces through a winnowing machine, performing primary softening treatment, tidying tea strips with hands, performing secondary softening treatment, performing secondary tea strip tidying treatment with hands, performing third-time softening treatment and roasting. The accurately controlled fresh leaves are tedded so as to obtain the most suitable fresh leaf enzyme-deactivated moisture content, the activity of fresh leaf enzymes is deactivated by contacting a heat-conducting roller for deactivation of enzymes, the moisture content of leaves needing to be removed in the fresh tea leaves is lower than the moisture content of buds needing to be preserved, the tea leaves immediately enter a needle-shaped tea roasting machine, the leaves needing to be removed are broken under the conditions of specific time, pressure and temperature and are blown by air, and the buds need to be kept perfectly; due to the dampening, softening and strip making process twice, straightness of tea buds can be preserved; and finally, due to roasting of a roasting unit, aroma of the tea leaves is generated, and the needed moisture content for refreshing the tea leaves is achieved.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and in particular relates to a fully automatic defoliating needle-bud tea processing method. Background technique [0002] Needle-bud-shaped tea is a large category of famous teas in my country, accounting for a large proportion of famous teas, such as Sichuan bamboo leaf green tea, Mengding yellow bud tea, Zhejiang Kaihua Longding tea, Guizhou green bud tea, etc. . These needle-bud-shaped famous teas are all made of single buds, and the requirements for raw materials are very strict, and no leaves can be mixed. However, with the sharp increase in picking costs, the quality of picking is declining year by year. The phenomenon of raw materials being mixed with leaves is very common. In the traditional processing process, it takes a lot of manual rubbing and rubbing to remove the leaves. The cost is high and the efficiency is extremely low.
