摘要: 为提高回潮后片烟含水率的稳定性,为后道润叶加料工序提供一个较稳定的片烟流量,对切片、回潮系统的控制方式进行了改进。将片烟流量由切片机的切片速度控制改为电子皮带秤流量控制;片烟含水率由通过操作人员设定加水量控制改为根据回潮后片烟含水率变化情况来调节加水量的自动控制。改进后效果明显,片烟流量的波动幅度由±1500kg下降到±200kg以内;含水率波动由±3%下降到±1%以内。Abstract: In order to improve the uniformity of moisture content and flow rate of conditioned tobacco lamina, the control of slicing and conditioning system was modified.The flow rate of sliced tobacco was controlled by electronic weighing belt instead of slicing speed;moisture content of conditioned tobacco was regulated automatically according to the variation of moisture content after conditioning.The fluctuation of flow rate of lamina was decreased from ±1500kg to ±200kg and that of moisture content of conditioned tobacco was reduced from ±3% to ±1%.
