预处理方法对再造烟叶中烟梗品质的影响

The research on tobacco stem pretreatment technology in the production of reconstituted tobacco

研究高压预处理、常规预处理两种工艺对烟梗理化特性、短梗萃取率及磨浆后浆料性质的影响。研究结果表明:高压预处理后烟梗的热水可溶物和乙醇可溶物含量均有一定程度的升高,提取效率提高,生产线效率得到提升;高压预处理及磨浆后烟梗产生的细小纤维量较少,有利于产品得率的提升;高压预处理后烟梗浆料动态滤水性能优于常规预处理烟梗,有利于浆料的抄造。

The effects on physical characteristics, chemical character- istics of tobacco stem, tobacco stem extraction rate and pulp proper ties after high pressure steam and conventional pretreatiment were investigated in this study. The results showed that the contents of hot water and ethanol soluble in the stem of the high pressure pre treatment increase to a certain extent, and the effieiencies of extrac tion and the production line were improved. The amount of fine fibers produced by the high pressure pretreatment after the defibrination was less, and this was beneficial to the improvement of the product yield. The dynamic filtration performance of the stem pulp after the high pressure pretreatment was better than that of the conventional pretreatment, which was good for paper making.
