Description

Technical Field

[0001] This invention relates to the field of cigarette product development and formula maintenance technology, and in particular to a method for calculating the contribution of a single-ingredient tobacco to the tar release of cigarettes. Background Technology

[0002] Tar release from cigarettes is a key indicator of product quality. Fluctuations in tar release not only affect the smoking experience and product quality stability, but also serve as a marker of cigarette toxicity. National standards impose strict tolerances on tar release levels. Cigarette tar primarily originates from the combustion of tobacco during smoking. Cigarette blends typically contain 10-30 different grades of tobacco leaves from various regions and years. The differences in characteristics between these grades directly or indirectly affect the tar release of the finished cigarette. Tobacco leaves are agricultural products; once a type of tobacco is used up, the blend needs to be maintained by recombining it with other tobacco leaves.

[0003] Currently, in the process of maintaining and adjusting leaf blend formulas, due to the lack of an effective method to accurately quantify the contribution of single tobacco leaves to tar release, even after adjusting the leaf blend formula to meet sensory quality requirements, the tar release often exceeds the national standard limit. This leads to formula adjustments relying on a large number of experiments and pilot-scale tests, which are frequent, long-term, and difficult. It is difficult to quickly identify the key tobacco leaf grades that affect the fluctuation of tar release, and it is impossible to provide scientific data support for formula optimization. This seriously affects the stability of product quality and the efficiency of formula adjustments.

[0004] Therefore, it is urgent to establish a scientific and feasible calculation method to accurately quantify the contribution of a single grade of tobacco leaves to tar release in finished cigarettes, and to solve the problems of high cost, low efficiency and poor targeting in the current formula adjustment. Summary of the Invention

[0005] In view of the problems existing in the prior art, the present invention provides a method for calculating the contribution of a single grade of tobacco to the tar release of cigarettes. The present invention aims to solve the technical problem that the contribution of a single grade of tobacco to the tar release of finished cigarettes cannot be accurately quantified in the adjustment of existing cigarette leaf blends, resulting in large fluctuations in tar release, many pilot tests, and great difficulty in formula maintenance. The present invention provides a method that can scientifically and accurately calculate the contribution of a single grade of tobacco to the tar release, and provides data support for formula design and maintenance.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This invention provides a method for calculating the contribution of a single-material tobacco to the tar release of cigarettes, the method comprising the following steps:

[0008] Each single-material cigarette was prepared using the three-paper-one-rod, tobacco-making, and rolling processes of the target finished cigarette, and single-material cigarettes that met the draw resistance standards of the finished cigarette were selected.

[0009] The tar release of the single-material tobacco cigarette is measured to obtain the unit tar release of the single-material tobacco cigarette; based on the unit tar release and the content of the corresponding single-material tobacco in the leaf blend formula, the tar release of the corresponding single-material tobacco in the leaf blend formula is calculated; based on the tar release of the single-material tobacco and the total tar release of all single-material tobaccos in the leaf blend formula, the contribution of the single-material tobacco to the total tar release of the cigarette is calculated.

[0010] The cigarette-making process of the target finished cigarette of this invention specifically includes: sequentially performing loosening and rehydration treatment, vacuum rehydration treatment, feeding treatment, leaf storage treatment, shredding treatment, tobacco shred rehydration treatment, drying treatment, and moisture balancing treatment on single-material tobacco, which are the same as the key steps in the product's tobacco-making process, to obtain a tobacco shred sample of the single-material tobacco. The tobacco shred sample of the single-material tobacco is then rolled using the same three-paper-one-rod and rolling process as the product to prepare a single-material cigarette with the same draw resistance as the product.

[0011] As a preferred technical solution of the present invention, the calculation formula I for the unit tar release of the single-material smoke is:

[0012]

[0013] Formula I

[0014] As a preferred technical solution of the present invention, the calculation formula II for the content of single-origin tobacco leaves in the leaf blend formula is as follows:

[0015]

[0016] Formula II

[0017] Where n is the total number of tobacco grades included in the leaf blend formula.

[0018] As a preferred technical solution of the present invention, the calculation formula III for the contribution of the single-material tobacco to the tar release of cigarettes is as follows:

[0019]

[0020] Formula III

[0021] As a preferred technical solution of the present invention, the tobacco processing technology of the target finished cigarette includes material preparation, loosening and rehydrating the tobacco leaves, vacuum rehydration, feeding, storing the leaves, cutting the tobacco, rehydrating the tobacco, drying the tobacco, and balancing the moisture content.

[0022] As a preferred technical solution of the present invention, the cigarette rolling and packaging process uses three sheets of paper and one stick of the same specifications as the finished cigarettes.

[0023] As a preferred technical solution of the present invention, the weight of the tobacco in the single-material cigarette is the weight difference between the single-material cigarette and the three-paper-one-stick cigarette.

[0024] This invention selects target single-material tobacco and processes the tobacco shreds strictly according to the key processes of finished cigarette manufacturing, ensuring that the processing conditions of single-material tobacco shreds are consistent with those of finished cigarette production.

[0025] As a preferred technical solution of the present invention, the tar release detection process should ensure that the smoking detection mode of the single-material cigarette is the same as that of the finished cigarette.

[0026] In cigarette standards, cigarette draw resistance refers to the resistance of smoke passing through the cigarette (including the tobacco section and the filter section) during the smoking process. It indirectly regulates the amount of tar released by affecting the combustion state, smoking behavior and the degree of smoke dilution. Therefore, the draw resistance of single-material standard cigarettes is consistent with that of finished cigarettes, which can ensure that the combustion state of the tobacco is close to that of finished cigarettes under the same smoking mode.

[0027] As a preferred technical solution of the present invention, the tar release detection process should ensure that the combustion environment of the tobacco shreds in the single-material tobacco is close to that of the finished cigarette.

[0028] As a preferred technical solution of the present invention, the tar release detection is carried out in accordance with the method specified in the national standard GB / T 19609 "Determination of total particulate matter and tar by a conventional analysis smoking machine for cigarettes".

[0029] Compared with existing technical solutions, the present invention has at least the following beneficial effects:

[0030] (1) This invention ensures that the test conditions of single-material tobacco are consistent with the production of finished cigarettes by simulating the production process conditions and actual combustion process of finished cigarettes, and the test data is true and reliable, providing accurate basic data for contribution calculation;

[0031] (2) For the first time, a contribution calculation model combining the tar release of single-material tobacco with the proportion of the formula was established, which can accurately quantify the actual contribution of each single-material tobacco to the tar release of finished cigarettes and identify the key tobacco grades that affect the fluctuation of tar release.

[0032] (3) It provides scientific data support for leaf group formulation maintenance, which can significantly reduce the frequency of experiments and pilot-scale tests during formulation adjustment, reduce the difficulty of formulation maintenance, and improve the efficiency of formulation optimization;

[0033] (4) It helps stabilize the tar release of finished cigarettes, ensures that the products meet the relevant national standards and regulations, and improves the stability of product quality and market competitiveness. Detailed Implementation
