对初烤烟(又称原烟)采取适当的方法吸湿,即是烤烟回潮。烟叶在调制干筋后,烟农或短期贮存,或分级出售,但在操作中叶片极易破碎。为了确保烤烟叶片完整,避免经济损失,在实践中常采取烤烟回潮。据研究,烤烟短期贮存水分以控制在14～15%为宜,外部特征为手感有干燥感觉,手握叶片有响声,较易破碎。分级出售水分以控制在16～18%为宜,外部特征是烟筋稍软不易断,手握叶片稍有响声,但不碎。实践证明,烤烟水分过低,破碎率增加,出丝 The first flue-cured tobacco (also known as the original smoke) to take appropriate method of moisture absorption, that is, flue-cured tobacco resurgence. After the dry leaves are prepared, the tobacco farmers are either stored for a short period of time or sold in grading, but the leaves are easily broken during operation. In order to ensure the integrity of flue-cured tobacco leaves, to avoid economic losses, in practice often take flue-cured tobacco resurgence. According to the study, short-term storage of flue-cured tobacco in the control of 14 to 15% is appropriate, the external characteristics of the feeling of dry feel, holding the leaves sound, easier to break. Grading the sale of water to control the 16 ~ 18% is appropriate, the external characteristics of tobacco is a little soft and not easy to break, holding the leaves a little noise, but not broken. Practice has proved that water is too low flue-cured tobacco, broken rate increased, a silk
