Method for measuring mixing uniformity of tobacco shreds of cigarettes

Abstract

The invention discloses a method for measuring the mixing uniformity of tobacco shreds of cigarettes, comprising the following steps: (1) selecting expanded tobacco shreds as tracers; (2) sampling; (3) separating; (4) drying; and (5) calculating the mixing uniformity. The use of the expanded tobacco shreds as the tracers has the following advantages that 1, the particle size and the distribution uniformity of the expanded tobacco shreds have little difference from other tobacco shreds, thus the expanded tobacco shreds can well represent the motion of the integral body, and can be used as the tracers; 2, the expanded tobacco shreds are one of common raw materials of a cigarette formula, and most cigarette formulas contain more than 3% of the expanded tobacco shreds; and 3, the expanded tobacco shreds have much smaller density than leaf shreds, stem shreds and papermaking sheet tobacco shreds, thus the expanded tobacco shreds can be completely separated by using the density difference through floating method. The separation solution used in the invention is a non-polar solution, thus the density changes of the components of the tobacco shreds caused by the intersolubility of the separation solution and the water in the tobacco shreds are avoided. The method has high measuring precision, and the precision is 0.08-0.66 %.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a method for measuring the mixing uniformity of shredded tobacco of cigarettes. Background technique [0002] Mixing generally refers to the process of uniformly spatially distributing solid particles of different physical and chemical properties. [0003] There are many mixing processes in the tobacco processing process, such as drum drying, flavoring, rolling and other processes. The mixing of solid materials is carried out throughout the tobacco processing process. The better the mixing effect, the better the stability of the physical and sensory quality of the product. [0004] Uniformity or degree of mixing is an important indicator to measure the effect of mixing. The Chinese patent "On-site Detection Method of Deep Cement Mixed Soil Quality Based on Mixing Uniformity" (CN1766642) introduces a method for evaluating the uniformity of the mixed soil and then eval...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to propose a method for measuring the blending uniformity in the cigarette processing process in view of the importance of the blending uniformity in the above-mentioned cigarette processing process and the inability of the existing related detection methods to truly reflect the uniformity of the cigarette processing process.
