根据传统的发酵参数、工艺和环境对茶叶品质的影响,设计了红茶自动发酵机控制系统。该系主要利用PLC分别控制蒸汽装置、超声波装置、传送装置、换气装置和温湿度装置,可实现恒温控制,并精准控制发酵房内的温度、湿度及循环换气时间等,更有利于茶叶的快速有氧发酵,达到提升茶叶鲜爽度、茶汤明亮度和叶底红艳等品质,为红茶的全自动生产提供了科学的参考依据。
According to the traditional fermentation parameters, process and environment on the quality of tea, the design of a black tea automatic fermentation machine control system. The system mainly uses PLC to control the steam device, the ultrasonic device, the transmission device, the ventilation device and the temperature and humidity device respectively to realize the constant temperature control and precisely controls the temperature, the humidity and the circulation ventilation time in the fermentation room and is more favorable to the tea leaf Of the rapid aerobic fermentation, to enhance the refreshing degree of tea, tea brighten the brightness and the end of Hongyan and other quality, fully automatic production of black tea provides a scientific reference.
