摘要
回填率是再造梗丝工艺的关键质量指标,目前的测定方法费时费力。为了建立简单、快捷的再造梗丝回填率测定方法,本文考察了再造梗丝回填率与其外观色差(基于空白梗丝)、白度之间的相关关系。结果表明线性关系成立,相关系数大于0.99,回填率越大,外观白度越小,再造梗丝与空白梗丝之间的色差越大。建立的工作模型准确度、精密度满足检测需求。
Backfilling ratio is a key quality index of reconstituted tobacco cut stem. Current measuring methods were inefficient. The aim of this paper was to establish a rapid method to solve the problem. Chromatic aberration and whiteness difference between treated reconstituted tobacco cut stem and control were measured by colorimeter. A significantly linear correlation was found between color and whiteness difference and backfilling ratio（r0.99）. Based on that, a working model was established and proved to meet the requirement of accuracy and precision.
