基于模糊PID控制的茶叶炭焙烘焙机设计与试验

针对目前茶叶木炭烘焙方式存在劳动强度大、效率低,炭烘焙温度不易控制导致茶叶品质差等问题,设计了一种采用自适应模糊P ID控制系统的智能茶叶炭焙烘焙机,控制系统经过两输入后进行模糊化等处理,实现三输出参数的实时变化,从而达到烘焙温度的设计要求.试验表明:烘焙20 m in后箱体内整体温度能够保持在(80±2)℃;香气测试...

Design and test of tea charcoal roasting machine based on fuzzy PID control

In view of the current tea charcoal roasting methods,there are problems such as high labor intensity,low efficiency,and difficult control of the carbon roasting temperature,resulting in poor tea quality.An intelligent tea charcoal roasting machine using an adaptive fuzzy PID control system is designed.The control system undergoes fuzzification and other processingafter two inputs to achieve real-time changes of three output parameters,so as to meet the design requirements of baking temperature.Experiments show that the overall temperature inside the box can be kept within(80±2)℃after baking for 20 minutes;the aroma test found that the content of charcoal baking trans-neryl alcohol,plant alcohol,and farnesene are all higher than electric baking,and the biochemical components in the tea are significantly different from electric baking.In the sensory evaluation comparison,the sensory evaluation score of charcoal roasted tea is 92.66 points,which is greater than the 91.44 points of electric baking.The charcoal roaster has stable performance during the roasting process,and the quality of roasted tea is better than electric roasting,which can effectively improve the roasting quality of tea.
