High-efficiency refining processing method for Mount Huangshan Mee tea

Abstract

The invention discloses a high-efficiency refining processing method for Mount Huangshan Mee tea. The high-efficiency refining processing method for the Mount Huangshan Mee tea adopts a three-dimensional semi-automatic processing system which is mainly based on mechanical coupling and artificially supplemented. The three-dimensional semi-automatic processing system comprises a first plane-surface round sifter for carrying out first round sieving on primary tea; and the three-dimensional semi-automatic processing system further comprises an upper-stage tea production line, a mid-stage tea production line and a lower-stage tea production line which are relatively connected to the first plane-surface round sifter. The upper-stage tea production line, the mid-stage tea production line and the lower-stage tea production line are integrated in one processing system according to characteristics of the primary tea of different specifications in the high-efficiency refining processing method for the Mount Huangshan Mee tea. The tea on the sifter is heated so as to carry out second drying, and then, winnowed by shaking the sifter; split-rolling and further sifter-shaking are carried out on the head No. 4 only; sifter-shaking, stalk-picking and winnowing are performed on the sieved tea so as to screen fixed blanks; and heating, second drying and grading are carried out on the fixed blanks. The high-efficiency refining processing method for the Mount Huangshan Mee tea has the advantages of high production efficiency, low broken tea rate, rational arrangement and small floor area. Productive practices have proven that daily output of the Mount Huangshan Mee tea by adopting the system can be up to 10000 kilograms, so that the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of refined processing of tea leaves, in particular to a high-efficiency refined processing method of Huangshanmei tea. Background technique [0002] Eyebrow tea is one of the treasures of green tea. Its shape is tight and even, the gray-green frost is oily, and it has a high fragrance and strong flavor. Mei tea originated in Tunxi, Xiuning, Yixian and Shexian in the Huangshan area of ​​Anhui Province at the junction of Anhui, Zhejiang and Jiangxi provinces, Wuyuan in Jiangxi Province and Chun'an, Jiande and Kaihua in Zhejiang Province. The tea with the widest production area, the highest output, the most stable sales area and the most common consumption in China. Because Huangshan eyebrow tea was processed and exported in Tunxi, Anhui in history, it is also called "Tunlu". The production area is located at the foot of Huangshan Mountain and beside the Xin'an River. The traditional Huangshanmei tea processing method ...

AI Technical Summary

Problems solved by technology

[0003] 1. Low production efficiency and high operating intensity

Each machinery and equipment in the existing workshop operates independently, and there is often a lack of corresponding conveying devices and buffer devices for connection between the equipment. When the production tempo of the link slows down, there will often be a large amount of material accumulation, which will affect the refining production efficiency

In addition, during the refining process of eyebrow tea, semi-finished products of various sizes will be formed depending on the number of sieves used, and these semi-finished products sometimes need to go through multiple processes such as re-fire, car color, shaking sieve, and yuan sieve. In the technology, the collection box is basically used to collect at the corresponding discharge port, and then carry out secondary processing of a number of heads when a certain processing volume is reached. The above scheme will easily make the equipment in the workshop occupy too much space and is difficult to arrange, and sometimes even Mistaking the collection box will happen, which will affect the quality of the product

In addition, most of the equipment is arranged in the workshop in an open style, which will inevitably cause tea ash and tea dust to fly around in the workshop, affecting the health of employees and even causing serious safety hazards

[0004] 2. The refining process is single, and the waste phenomenon is serious

At present, the refining process of eyebrow tea is all aimed at the finishing treatment of raw tea with moderate tea grain size, but there are few reports on the treatment of raw tea head, 8-hole and below sieve tea, because the tea grain size of these two kinds of raw tea The difference is very large, and the ordinary refining process cannot be applied

In addition, the refining process of various types of tea grains has not been systematically processed, resulting in waste of equipment use

[0005] 3. Tea leaves produced by traditional refining methods have a high breakage rate and low quality

At present, in the refining process of Huangshan eyebrow tea, if one wants to produce high-quality tea leaves, some processes often need to be repeated many times. However, repeated processing will inevitably lead to an increase in the broken rate of eyebrow tea. The specific times of existing screening are determined by Manual judgment, human factors are relatively large, the quality of the sieved tea is uneven, and it also directly restricts the refining efficiency

[0006] In view of this, how to design a refined processing system of Huangshanmei tea to solve the problems of low production efficiency, high crushing rate and large space occupation in the existing methods has become a technical problem to be solved urgently in this field
