AUTOMATIC CONTROL OF BLACK TEA FERMENTATION TECHNOLOGY PARAMETERS BASED ON FUZZY LOGIC AND COMPUTER VISION

Abstract

Black tea is one of the most popular drinks with many good values that it brings to people. In the production of black tea, fermentation is the most important factor that determines the quality of tea. The technological parameters that need to be adjusted during the fermentation of black tea include fermentation time, temperature and humidity. This paper introduces an automatic line that controls the OTD black tea fermentation process. The observation and control of technological parameters is done at 3 times with 3 positions on the conveyor belt, including 2 positions for humidity control and 1 position for speed control. Observation and adjustment are made automatically based on computer vision, image processing and fuzzy logic. The research results, which have been implemented experimentally in practice, show that the proposed system works precisely, stably and reliably.
