摘要
This study was conducted to further classify threshed strips, so as to broaden the usable range of raw material and facilitate the effective utilization of to- bacco resource. During the threshing and redwing process, various process param- eters including the rotating speeds of threshing drums of threshing machioe, draught fans and fling drums were scientifically and rationally set according to the actual quality of the raw material. According to the characteristic that strips with close in- herent quality have basically the same specific gravity and leaf thickness, the strips from each discharge hole were accurately evaluated, and classified, followed by redrying and packaging. The results showed that the threshing and separating pro- cedure could improve the separating effect and precision according to tobacco qual- ity, so as to satisfy the separation and classification requirements for tobacco.
为了将打后片烟进行细化分类,拓宽原料使用范围,有效利用原料资源。研究了在打叶复烤过程中,依据来料实际质量状况,科学、合理设置打叶机打辊转速、风机转速、抛料辊抛速等各项工艺参数,然后根据片烟内在质量相近其比重和身份也基本相同的特点,将各个风分下料口的片烟准确评价、优化组合,分类复烤、包装。结果表明:在打叶风分工序能够按质提高风分效果和精度,满足烟叶风选分类要求。
