摘要
应用在2012年“中华”专用分拣复烤生产线中采集的7个产地的复烤前原烟和复烤后片烟的在线近红外光谱为试验资料, 通过建立不同产地近红外光谱的投影分析模型, 并结合方差及相关分析等, 研究烟叶复烤前后的均一性及相似性等品质特征的变化, 为客观的掌握烟叶原料质量及卷烟产品配方提供技术支撑。 本研究结果表明, 从数量庞大的在线近红外光谱中, 按等间隔采样时间筛选约1万条左右用于建模分析可行, 取样代表性充分;经人工分拣、 打叶、 复烤后的各产地烟叶近红外光谱的均一性提高幅度可达10%~35%, 烟叶品质的均质化程度显著提高;同时复烤后各产地烟叶所体现的相似性关系亦发生了变化, 从整体上其相似性显著降低, 即由产地体现的风格品质差异显著提升, 为优质卷烟的原料配方设计提供了更大空间, 体现了我国烟草企业生产优质中式卷烟需要消耗大量财力、 人力进行烟叶复烤加工的必要性。 传统的化学分析等手段需要花费大量的时间和精力, 难以对整个加工环节进行控制, 近红外光谱技术以其快速、 无损的优势, 不仅能够实现待测样品成分含量等的实时检测与质量控制, 而且应用生产过程中的大量近红外光谱, 可以从多角度进行有关产品品质信息的充分挖掘, 是一种在众多行业特别是农产品和食品加工行业中极具应用前景的在线分析检测技术。
Abstract
In this paper, the 7 different origin before redrying raw tobacco & after redrying sheet tobacco’s online near infrared spectroscopy were collected from sorting & redrying production line specifically for “ZHONGHUA” brand. By using the projection model bulit by different origin tobacco’s online spectroscopy and the method of variance and correlation analysis, we studied the uniformity and similarity quality characteristics change before and after the redrying of tobacco, which can provide support for understanding the quality of the tobacco material and cigarette product formulations. This study show that selecting about 10 000 by equally spaced sampling time from a huge number of online near infrared spectroscopy, for modeling are feasible, and representative. After manual sorting, threshing, and redrying, the uiformity of each origin tobacco near-infrared spectroscopy can be increased by 10%~35%, homogeneity of the tobacco leaf has been significantly improved. After redrying, the similar relationship embodied in the origin also have significant changes, overall it reduce significantly, that shows the quality differences embodied by origin significantly improve, which can provide greater space for formulations, it shows the need for high-quality Chinese cigarette production requires large amounts of financial and human resources to implement cured tobacco processing. The traditional means of chemical analysis, it takes a lot of time and effort, it is difficult to control the entire processing chain, Near Infrared Spectroscopy with its rapid, non-destructive advantage, not only can achieve real-time detection and quality control, but also can take full advantage of near-infrared spectroscopy information created in the production process, which is a very promising online analytical detection technology in many industries especially in the agricultural and food processing industries.
