Design and Process Optimization of a Continuous Production Line on Needle-type Premium Green Tea
摘要
Abstract
According to the quality and processing characteristics of needle-type premium green tea, a strongly practicable, energy-efficient and highly qualified needle-type premium green tea continuous production line which consisted of the fresh tea leaves artificial spreading machine, electromagnetic heat roller fixation machine, multiphase continuous fixation-shaping machine, rubbing machine, far-infrared raising fragrant machine and other energy efficient facilities was organized. The processing procedures of the continuous production line including spreading, fixation, fixation-shaping and baking were investigated and a complete set of processing technology about the line on needle-typepremium green tea was proposed. The results showed that the best process parameters were: temperature at 18-25℃ and humidity at 60%-90% for fresh tea leaves spreading, the leaf weight of 125 kg·h-1, baking temperature at 270℃ and time of 65 second for the fixing, 240℃(38 Hz), 210℃(40 Hz) and 180℃(45 Hz) for the multiphase continuous fixation-shaping, and drying temperature at 40-55℃, baking temperature at 100℃, speed of 30 kg·h-1 for the rotary continuous drying.关键词
