Problems solved by technology

One is to completely imitate the principle of manual design of processing machinery to achieve stand-alone operations, such as plate-type Longjing tea frying machine, pressure head-type Longjing tea frying machine and computer-type Longjing tea frying machine, etc., in one machine to complete green pot and brilliance pot Operation, this is in patent literature (Wang Yuanchang, patent application number: 02215481, Sun Cheng, patent application number: 200610049961, Shi Nengwen, patent application number: 200420020157, Hong Tianming, patent application number: 03208330, etc.) and non-patent literature (Zheng Wenjia. Research report on innovative application of three-pot flat tea machine. Guizhou Tea, 2006, (3): 28-29; : 154-158; Zhuang Jianliang, Development and operation of automatic Longjing tea frying machine. Shandong Agricultural Mechanization, 2008, (4): 20) have reported that the yield of this production method is low, and the smoothness of tea leaves is poor. The ropes are severely broken and are only suitable for small workshops.
The second is semi-mechanical and semi-manual production, which uses a green-fixing machine to finish greening, a multi-function machine for famous tea to shape, and hand-assisted potting. .1998, (3): 27; Chen Yuqiong. Research on the new process of mechanism Longjing tea. 2007, (1): 33-35) have been reported. This processing method still has the problems of low production efficiency and high labor intensity

Embodiment 1

[0022] Embodiment 1: the optimization of method parameter

[0023] Use one bud and one leaf of the Fuding large white tea tree variety as the material, mix the fresh leaves evenly, spread them according to the method of spreading—finishing (6CST-40 type roller continuous greening machine, Zhejiang Lvfeng Machinery Co., Ltd.)—spreading to cool and regain moisture—trimming ( 11-slot carding machine, Zhejiang Lvfeng Machinery Co., Ltd.)—flattening and shaping (6CLZ-60 reciprocating multipurpose machine, Zhejiang Lvfeng Machinery Co., Ltd.)—cooling and regaining moisture—solid shape (6CBG-60 flat tea solidification machine , Zhejiang Lvfeng Machinery Co., Ltd.) to Zugan process operation, to study the difference in the quality of flat tea treated with strips and without strips. The sensory evaluation results show that the tea samples treated with strips after finishing have a higher score, and the strips The cable is tight and straight, the leaves cover the buds, flat and smooth, ...

Embodiment 2

[0027] Embodiment 2: Do the optimization of shape parameters

[0028] Use one bud and one leaf of the Fuding large white tea tree variety as the material, mix the fresh leaves evenly, and spread them according to the method of spreading—finishing (6CST-40 type drum continuous greening machine)—spreading to cool and regain moisture—trimming (11-slot stripping machine)— Squeeze and shape (6CLZ-60 reciprocating multi-purpose machine)—spread to cool and regain moisture—solidify (6CBG-60 flat tea solidifying machine, until dry enough) process operation, compare the influence of water content of shaped leaves on quality, According to the analysis of the main quality components (Table 3) and the sensory evaluation results (Table 4), combined with the actual production, the process parameters of the multi-purpose machine are obtained: the water content of solid leaves is 15-20%.

[0029] Table 3 is the analysis result of the main quality components of flat famous tea with the water co...

Embodiment 3

[0036] Embodiment 3: Solid parameter optimization

[0037] Use one bud and one leaf of the Fuding large white tea tree variety as the material, mix the fresh leaves evenly, and spread them according to the method of spreading—finishing (6CST-40 type drum continuous greening machine)—spreading to cool and regain moisture—trimming (11-slot stripping machine)— The process of flattening and forming (6CLZ-60 reciprocating multi-purpose machine, instrument temperature 120-130°C, 3 catties of leaves per pot)-spreading to cool and regain moisture-solid (6CBG-60 flat tea solidifying machine, until dry enough) Process operation. On the basis of the single factor experiment of water content before solidification, solidification temperature and solidification leaf amount, L 9 (3 4 ) Orthogonal experimental design method to optimize the solid parameters, and the factors and levels of the orthogonal design are shown in Table 5. The sensory evaluation results of single factor test of solid ...

Abstract

The invention belongs to the technical field of tea manufacture, in particular to a method for mechanically processing flat green tea. The method is characterized in that fresh green tea leaves are prepared into well-known tea with a flat shape through spreading, enzyme deactivating, sorting, pressing, solidifying, flavoring and other steps. The flat well-know tea has the characteristics of flat and smooth strips, no fragment, unpolished rice like color and luster, constant chestnut fragrance, green and bright color of liquor color, fresh and pure taste, tender, uniform, green and bright leaves and the like. The tea quality can completely reach the level of manually processing, and the method is applicable to mechanical processing production.

Description

technical field [0001] The invention belongs to the technical field of tea making, and in particular relates to a mechanized processing method of flat green tea. Background technique [0002] Flat green tea is one of the main teas of my country's famous green tea. According to the difference in processing technology and quality, flat green tea is divided into two categories: one is represented by Jingting Lvxue, the appearance quality requires flat strands, green color, and pekoe exposed. Shape-drying, this kind of famous tea has been mechanized. The other type is represented by Longjing tea, which requires flat and smooth cords without breakage and brown beige in color. Due to the low work efficiency and high labor intensity of manual production, the quality is also unstable, which affects the economic benefits. The mechanized processing technology about this type of flat tea mainly contains the following two forms. One is to completely imitate the principle of manual d...
