摘要
目前我国烤烟生产上推广的多为自然气流上升(下降)式烤房,气流自然上升(下降)在一定程度上限制了升温、排湿的灵敏性。主动式烟叶烘烤自动控制系统在地洞进风口、天窗上安装有动力通风排湿设备并应用模糊控制理论,将PID控制和单片机技术引入,将不同品种、部位烟叶烘烤工艺曲线固化于单片机芯片中。在烟叶烘烤过程中,对实时监测结果进行模糊自整定PID控制,实现了烟叶烘烤全过程的自动控制。与普通烤房相比,烤后烟叶色泽饱满,鲜艳,叶片颜色均匀,上等烟比例提高8.8个百分点,每千克干烟均价提高0.93元,并且大幅度降低烘烤劳动强度,减少用工,提高了烟叶综合效益。
In order to improve the curing quality of tobacco leaf,study was conducted on the initia-tive automatic control flue-curing barn with automatic control system.The results showed that the cured to-bacco leaf was lustrous,bright and uniform in color.The proportion of superior leaf percentage increased8.8and average price increased0.93yuan/kg.Application of such flue-curing barn could reduce the cur-ing and operation time markedly,improve the comprehensive performance and meet the needs of tobacco leaf curing.
