Closed type tea leaf selecting method

Abstract

The invention discloses a closed type tea leaf selecting method. Primary air separation, color sorting, secondary air separation and visual sorting are carried out in an enclosed space. Separating efficiency is improved, separating cost is lowered, a vibrating screen is not used in the whole process, the damage of separation to tea leaves is lowered to be minimum degree, the entire tea leaf separating stage is performed under a closed environment, and the external environment can not be polluted.

Description

technical field [0001] The invention relates to a closed tea selection method, which belongs to the field of tea selection and separation. Background technique [0002] According to incomplete statistics, the output value of the famous and high-quality tea, which accounts for less than 5% of the total tea output in my country, has reached more than 20% of the total output value, indicating that the better the quality of the tea, the higher the value, and the more significant the economic benefits. Although the output and sales of tea in my country are large, due to the lack of scientific tea quality testing and tea grading technology, it is difficult to quickly and objectively identify the quality and grade of tea. At present, there is a lot of randomness in the grading of tea in the market, which affects the production and management of tea. At the same time, as the technical standards of green technical trade barriers in developed countries are getting higher and higher, ...
