浸梗工艺探讨

Discussion on Stem Dipping

为简化烟梗预处理工艺,提高烟梗处理质量,进行了浸梗工艺试验。结果表明,新烟梗的处理时间最短,60℃水温时,经过5s的浸泡时间处理后,滤去水分,在环境温度(25±2)℃和相对湿度(68±5)%的条件下存放4h,烟梗的浸透率可达到99%以上,含水率为36.27%;相同库存期、不同产区的复烤后烟梗的处理时间稍有差别;同一产区的复烤后烟梗随着库存期的延长,所需的处理时间也长;在适宜的水温条件下,当浸泡时间达到60s时,烟梗的浸透率趋于一致。

In order to simplify stem pretreatment and improve processing quality, the experiments on stem dipping in water were conducted. The results showed that the time needed for treating green stem was the shortest, dipped in 60℃ water for 5 seconds, filtrated, then stored for 4 hours （air temperature 25±2℃, relative humidity 60±5%）, the degree of water permeation and moisture content of stem could reach 〉 99% and 36.27%, respectively. The time needed for treating redried stem with the same storage time varied slightly depended on where the tobacco was grown, while the time needed for redried stem from the same area prolonged with the length of storage time. Any stem dipped in water at proper temperature for one minute would reach the same degree of water permeation.
