Embodiment Construction

[0036] The present invention is further set forth below in conjunction with embodiment. It should be understood that the examples are only used to illustrate the present invention, not to limit the scope of the present invention.

[0037] see figure 1 , the invention discloses a method for testing the homogenization process of finished tobacco sheets obtained by threshing and redrying, which is used to detect and evaluate the effect of the homogenization method adopted in the threshing and redrying process on certain The homogenization effect of a chemical composition. It first samples the finished tobacco sheets that have been regulated by the threshing and redrying process and the homogenization method according to the order of boxing on the production line, and marks them as the first sample, the second sample,... , the i-th sample, ..., the n-th sample. The n samples are tested by near-infrared spectroscopy to obtain the chemical values ​​of the corresponding chemical c...

Abstract

The invention provides a method for testing the homogeneous control effect in the threshing and redrying process. The method sequentially comprises the following steps: extracting a homogeneously controlled finished product to obtain a sample, carrying out laboratory detection on the extracted sample, recording the spectrogram and obtaining the chemical value corresponding to chemical components to be tested, and calculating the integral variation coefficient, the local variation coefficient and the covariant variation coefficient of the chemical value corresponding to the chemical components to be tested. The uniformity of sheet tobacco is evaluated through the integral variation coefficient, the local variation coefficient and the covariant variation coefficient controlled in the oriented procedure, so the effectiveness and the stability of the homogeneous control method are systemically reflected.

Description

technical field [0001] The invention relates to the field of production control in tobacco, and specifically discloses a method for testing the effect of homogenization control in threshing and redrying. Background technique [0002] With the increasing output of various types of cigarettes, how to ensure that the internal chemical composition of raw materials after threshing and re-baking is uniform is increasingly important for the quality and stability of cigarette products. [0003] In recent years, with the maturity of online near-infrared spectrometer technology, its rapid detection and timely feedback just make up for the above-mentioned technical difficulties. The near-infrared rapid detection method can detect several chemical indicators at the same time, which brings great convenience to the personalized processing requirements of industrial enterprises. The use of near-infrared technology to regulate the uniformity of tobacco raw materials has been reported in re...
