Problems solved by technology

[0003] At present, the cumulative blending accuracy is mostly used in the industry to evaluate the uniformity of tobacco blending. This evaluation method can only roughly evaluate whether a batch of products are generally mixed according to the formula, but it cannot judge whether each component in the tobacco is consistent in the micro unit. The formula conforms to the design, and it is impossible to judge whether the shredded tobacco is evenly distributed in the three-dimensional space

Embodiment 1

[0036] 1. Taking the expanded shredded tobacco as a marker, accurately weigh each component of the corresponding multiple groups of shredded tobacco according to the different setting ratio x (i.e. the actual mixing ratio) of the expanded shredded leaf, and then carry out all the components of each group of shredded tobacco Manual mixing, the weight of each group of mixed shredded tobacco is 10g; after drying, weigh accurately, put the shredded tobacco into a beaker of 1000ml (10g mixture needs 1000ml for actual operation) filled with cyclohexane, stir it with a glass rod, and let it stand for 1 minute Finally, use a steel wire filter spoon to fish out the upper layer components, let it air in the fume hood for 5 minutes, remove a small amount of shredded stems, dry and weigh accurately, and calculate the ratio y of expanded shredded leaves in shredded tobacco. Establish a standard curve between the detected ratio and the set ratio: y=1.0787x+0.006, as shown in Figure (1).

[0041] 1. Taking the expanded shredded tobacco as a marker, accurately weigh each component of the corresponding multiple groups of shredded tobacco according to the different setting ratio x (i.e. the actual mixing ratio) of the expanded shredded leaf, and then carry out all the components of each group of shredded tobacco Manual mixing, the weight of each group of mixed cut tobacco is 15g; after drying, weigh accurately, put the cut tobacco into a 1000ml beaker filled with acetone, stir with a glass rod, and after standing for 1 minute, use a steel wire filter spoon to scoop out the upper layer components and ventilate After airing in the cupboard for 5 minutes, remove a small amount of shredded stems, dry them and weigh them accurately, and calculate the ratio y of the expanded shredded leaves in the shredded tobacco. Establish a standard curve between the detected ratio and the set ratio: y=1.0787x+0.006, as shown in Figure (1).

Abstract

The invention relates to a method for evaluating the cut tobacco mixing uniformity. The method comprises the following steps: 1, weighing corresponding components of a plurality of cut tobacco groups according to different preset proportions x of expanded cut tobacco leaves, and respectively manually mixing; 2, respectively separating out the expanded cut tobacco leaves from the cut tobacco groups through an organic solvent, and calculating to obtain the proportion y of corresponding expanded cut tobacco leaves in each cut tobacco group; 3, establishing a y-x standard curve; 4, sampling the cut tobacco to be tested several times, separating out the expanded cut tobacco leaves from each sample through the organic solvent, and calculating the proportion y' of the expanded cut tobacco leavesin each sample; 5, calculating according to the standard curve to obtain the real mixing proportion x' of each cut tobacco sample; and 6, calculating to obtain the sampled cut tobacco uniformity coefficient. According to the invention, the feasible evaluation method is provided for the accurate and objective cut tobacco uniformity evaluation, reliable technological parameters and evaluation data are provided, and the method has important meanings to the production process stability control, the cut tobacco mixing uniformity control and the cigarette quality index control.

Description

technical field [0001] The invention relates to the field of quality monitoring of cigarette products, in particular to a method for monitoring product uniformity in the cigarette production process, in particular to an evaluation method for mixing uniformity of shredded tobacco. Background technique [0002] In the process of cigarette production, timely and accurate monitoring of product uniformity and stability is of great significance for improving the quality of cigarette products. At present, most domestic cigarette companies can only test the end products of cigarettes, and lack accurate monitoring and measurement methods for process control accuracy. The uniformity and stability of shredded tobacco components has a high correlation with the sensory quality of cigarette products and the stability of smoke indicators. The uniformity of shredded tobacco is one of the important factors affecting the internal quality stability of cigarette products. The uneven distributio...
