福建省龙岩地区,三十多年来一直沿用“变黄期闭窗变黄,定色期开窗排湿”的烘烤技术(以下简称闭窗烘烤)。由于多雨季节鲜烟含水量大,变黄期又不开窗,加上房外空气湿度大,往往造成定色期排湿不畅,定色困难,因而降低烟叶质量,甚至烤成黑糟烟,损失严重。为了提高烟叶烘烤质量,1983—1985年我们进行了多次试验,把变黄期闭窗不排湿改为开窗早排湿。结果表明,新方法能够提高烟叶 Longyan area of ​​Fujian Province, for more than thirty years, has been using the “yellowing turn yellow period, fixed-color window wet” technology (hereinafter referred to as window baking). Due to the heavy rainy season, the moisture content of fresh tobacco is large, and the yellowing stage does not open the window. In addition, the humidity of the outdoor air is high, which often results in poor wetting during the fixing period and difficult color fixing, thereby reducing the quality of the tobacco leaf and even baking the black smoke , Serious loss. In order to improve the quality of tobacco baking, we conducted a number of tests from 1983 to 1985, and changed the window drying in the yellowing stage to the window wetting in the early stage. The results show that the new method can improve tobacco leaf
