Abstract

The invention belongs to the technical field of black tea detection equipment, and particularly relates to a black tea fermentation process real-time detection system. According to the detection system, the matching degree between the image features of the fermented leaves and the fermentation degree and the accuracy degree of the model are improved, and the judgment efficiency and the judgment accuracy of the moderate fermentation stage of the black tea are most accurately guaranteed. The method comprises establishment of a fermentation degree digital classification label and establishment of a fermentation degree discrimination model, and comprises the following steps: 1) establishment of the fermentation degree digital classification label; 2) establishment of a fermentation degree discrimination model; and 3) performing morphological identification on the fermented leaves through the fermentation degree discrimination model so as to judge which stage the fermentation degree of the current fermented leaves is in.

Description

A real-time detection system for black tea fermentation process technical field The invention belongs to the black tea detection equipment technical field, be specifically related to a kind of black tea fermentation process real-time detection system. Background technique [0002] The primary process of black tea processing is mainly withering, rolling, fermentation, and drying. Black tea fermentation is mainly based on polyphenols The enzymatic oxidation of tea is the main process of forming theaflavins, thearubigins and theabrownins, and the color of the tea leaves is green-yellow-red. It is the key to forming the quality characteristics of red leaves in black tea and black soup, and the degree of fermentation is insufficient or excessive, which seriously affects the quality of black tea. Currently, The degree of fermentation depends on human experience, or manual control of the process based on simple process parameters such as temperature, humidity and time. but ...
