摘　　要：为解决黑茶发酵过程中翻堆降温的问题,设计一种黑茶翻堆设备,并在溧阳进行试验研究。利用该设备在长10m、底宽1m、高0.5m的渥堆上进行翻堆,取辊筒外圆线速度与前进速度的比值分别为90、120、150,以翻堆前后的温差、含水率变化和蓬松率作为试验指标,对设备的辊筒外圆线速度和前进速度进行正交试验。试验结果表明,在一定范围内,影响温差变化最大的是辊筒线速度;影响含水率变化最大的是辊筒线速度和前进速度的速比;影响蓬松率最大的是前进速度。In order to solve the problem of turning of dark tea fermentation process,a kind of dark tea turning device was designed,and the experimental study was carried out in Liyang.It was made the device turning operation in the pile of long 10 m,bottom width1 m,height 0.5m,under the condition of the ratio of the roller external circle line speed and the speed is respectively 90,120,150.There were temperature difference,moisture content changes and fluffy rate as the test indexes.The orthogonal test was studied by the roller external circle line speed and the speed.Test results show that,in a certain condition,the roller external circle line speed is the biggest factor of temperature difference,the ratio is the biggest factor of moisture content change,the speed is the biggest factor of fluffy rate.
