Method for determining blending proportion of expanded cut stem in cut tobacco

Abstract

The invention relates to a method for determining the blending proportion of expanded cut stem in cut tobacco. The method comprises the following steps of: a, manually blending the expanded cut stem with other components of the cut tobacco according to a preset blending proportion and recording the proportional value; b, balancing the blended cut tobacco; c, determining the total plant alkaloid content of the balanced cut tobacco by utilizing a flow analyser; d, fitting according to the value of the total plant alkaloid content and the recorded blending proportional ratio value to obtain an expanded cut stem blending proportion predicting model; e, balancing the cut tobacco in formula content the expanded cut stem blending proportion of which is required to be determined in the actual process; f, determining the total plant alkaloid content of the balanced cut tobacco by utilizing the flow analyser; and g, calculating the expanded cut stem blending proportion of the cut tobacco in formula content in the actual process. By applying the invention, technical parameters can be provided for correctly controlling the blending proportion of the cut stem in the cut tobacco in formula content, and support can be provided for stabilizing the physical quality and sensory quality of cigarette products.

Description

A method for measuring the blending ratio of expanded cut stems in shredded tobacco technical field The invention relates to a method for measuring the mixing ratio of expanded cut stems in shredded tobacco. Background technique Tobacco stems account for about 30% of the total tobacco leaves and are the main by-products of the tobacco industry. Due to their high cellulose content and low sugar and alkali components, tobacco stems are usually used as shredded stems or made into thin sheets to increase the filling value of cigarettes. It is beneficial to reduce coke, which is also one of the main ways to utilize tobacco stems. The various blends in the formula shredded tobacco mainly include: shredded leaves, shredded expanded leaves, shredded expanded stems, paper-making flakes, rolling flakes, shredded flakes, and the like. At present, domestic tobacco companies usually use part of the expanded shredded stem as the ingredient tobacco and roll it into finished cigarettes....

Problems solved by technology

Chinese patent applications 200610018051.2, 200610018050.8, and 200910065223.5 all use the difference in apparent density of tobacco materials with different blending components in the shredded tobacco, and use the method of configuring organic solvents with different densities to separate the different blending components in the shredded tobacco, and then obtain the blended tobacco. The blending ratio of compound in shredded tobacco, because the density of expanded shredded tobacco is quite different from other blended substances in shredded blended tobacco, the method of the above patent can effectively separate the shredded shredded expanded leaf, but in the actual process, the expanded shredded stem The density difference between silk, leaf silk and flake silk is very small, it is not easy to select an organic solvent with a suitable density to separate it

However, the method involved in Chinese patent application 200610018085.8 is to manually select under a magnifying glass according to the different appearance characteristics of each blending component in the shredded tobacco. Determination of silk blending ratio
