Chemical cleaning of cylinder drying machine used in textile dyeing and finishing;
纺织染整烘筒烘燥机的化学清洗
The result indicated that, It takes longer time over curing on 42℃and 54℃ with wo-prolonged one-low curing mode than with conventionality curing mode.
结果表明:采用"两拖一低"烘烤模式在42℃、54℃左右较常规烘烤模式维持的时间较长,烟叶内各种酶的活性较高且持续,有利于大分子物质的降解,烤后的烟叶化学成分比较协调,还原糖含量较高,淀粉含量较低;外观质量得到改善,叶片结构疏松,身份适中,弹性好,桔黄烟叶较多,基本杜绝了青筋烟;烟叶烘烤质量有较大幅度提高,中部烟叶上等烟比例提高了13。
