Background
In order to enrich smoke or create heated cigarettes with different styles and tastes, a certain amount of feed liquid is applied by a feed liquid applying device in a flow casting mode before the cut tobacco is gathered into bundles, so the applied feed liquid is generally in the center of a tobacco section, the cut tobacco in the cigarettes directly contacted with the feed liquid only accounts for about 10 percent of the total amount of the cut tobacco, and the feed liquid is required to be gradually and uniformly diffused by the feed liquid; because the boiling point of the liquid material for heating the cigarette is generally higher and the diffusion speed is slower, if the liquid material does not reach a uniform state, the stability of mouth-to-mouth smoking of the heated cigarette is influenced.
The diffusion rate of the applied feed liquid in the cigarettes is related to the composition of the feed liquid, the concentration of the feed liquid, the environmental temperature and the like, but the specific correlation degree cannot be detected at present, so that the heated cigarettes are delivered to consumers after being stored for a uniform time, and the cigarettes are not uniformly diffused and are possibly uniformly diffused all the time, and the quality stability of the heated cigarettes cannot be ensured.

Detailed Description
The technical solutions of the present invention are described in detail below by examples, and the following examples are only exemplary and can be used only for explaining and explaining the technical solutions of the present invention, but not construed as limiting the technical solutions of the present invention.
In the production process of heating cigarettes, the application liquid is added in the central position before gathering the cigarettes into bundles so as to meet a certain set purpose requirement, while cigarettes of certain brands are usually kept unchanged in production, but the diffusion rate of the application liquid is different at different storage temperatures, so that the storage space cannot be better utilized, the temperature change can be generally understood as seasonal change, because the produced cigarettes cannot be stored at constant temperature in the storage warehouse due to space, energy and the like, all the warehouses for storing the cigarettes are conventional warehouses and can change along with the temperature change of an external environment, but when the external environment is summer, the temperature is high, the diffusion rate of the application liquid is high, and when the external environment is winter, the temperature is low, the diffusion rate is low, and the temperature change also exists in spring and autumn, this makes it difficult to determine the correct storage time to ensure a consistent quality of the heated cigarettes.
Therefore, the method for stabilizing the diffusion rate of the feed liquid applied in the heated cigarette is provided, so that the time for complete diffusion of the heated cigarette is ensured even if the storage temperature is changed, the quality is ensured, and meanwhile, the warehouse management workload is reduced and the warehouse management is simplified.
Firstly, establishing a diffusion model of the applied feed liquid in the heated cigarette, comprising the following steps:
because the tobacco shreds of different brands of heated cigarettes have different proportions, and the original flavor, tar content and the like of the tobacco shreds may be different, the amount of the application liquid in the heated cigarettes of different brands is different, namely the amount of a certain solute applied is different.
Sampling the cut tobacco used for producing the formula (the cut tobacco can be prepared from slices) in a random sampling mode, taking the cut tobacco as a basic cut tobacco sample, and sealing and storing the cut tobacco sample in a set environment.
The obtained basic tobacco shred samples are rolled into cigarettes of heating cigarettes, the rolled cigarettes are evenly divided into M parts, in the application, M is a natural number larger than 2, in the embodiment, M is selected to be 5, namely the rolled cigarettes are divided into 5 parts, and similarly, 5 kinds of applying material liquid with different concentrations are prepared by applying the material liquid according to different weight percentage concentrations. In other embodiments of the present application, M may be set to a larger number of parts, for example, 10 parts, 15 parts, 20 parts, or the like, as necessary, but in consideration of the ease of changing the concentration of the feed liquid in actual production, it is determined that M is not suitable for the fine division.
The method comprises the steps of injecting the liquid applying material with each concentration to the center of each cigarette by using an injector, specifically, injecting the liquid applying material with the same concentration into each cigarette, then dividing each cigarette into N parts, in the embodiment, selecting 5N parts, namely 5 parts, namely dividing the cigarette into 25 parts in total, then respectively placing the 5 parts separated from the cigarettes injected with the liquid applying material with the same concentration into devices with different storage temperatures (in the application, the influence of humidity is not considered, the same humidity is taken as an example for explanation), in the embodiment, different temperature differentiation can be carried out for different areas, in the embodiment, storage at-10 ℃, 0 ℃, 10 ℃, 20 ℃ and 30 ℃ is selected for storage for set days, and the specific storage time can be respectively detected according to the storage time of 3-20 days or any time within the range, in this embodiment, for illustration only, samples stored for 5 days are selected for detection, and in a normal case, selecting a sample at a single time for detection may result in that the accuracy of detected data may not represent actual data, because in the diffusion process, the rate at the early stage of diffusion is large, and the rate at the later stage of diffusion is reduced, and generally, a manner of performing corresponding detection on the above ranges and then taking an average value should be selected to determine the diffusion rate.
The specific diffusion rate of the application liquid is determined by detecting the solvent in the application liquid, in this application, the solvent is selected from propylene glycol or glycerol, and in this embodiment, glycerol is taken as an example for illustration.
The cigarette that takes out any part and store 5 days is from extracting the pipe tobacco with the position in the cigarette and setting for the pipe tobacco of position to handle respectively, in this application, adopt the extraction method to detect with the preparation of calibration liquid, it is specific:
weighing a tobacco shred sample with a set weight, placing the tobacco shred sample in a 500mL beaker, immersing the tobacco shred sample with 300mL of methanol for a set value +/-2 s, filtering out the tobacco shred sample, shaking up the filtrate, taking 20.0 mu L of 30.0g/L methanol solution of 1, 3-butanediol internal standard, and shaking up the supernatant of the filtrate until the volume is 1 mL. The 10 samples were processed accordingly.

mass spectrum conditions: an ionization mode: EI; ion source temperature: 230 ℃; transmission line temperature: 230 ℃; scanning range: 33-450 amu.
Through the detection, the glycerol content of the central position of each cigarette is respectively obtained, the glycerol content of the position is set, and then the diffusion rates of the application liquid at different temperatures and the same weight percentage concentration are respectively obtained by utilizing a cigarette application liquid diffusion rate formula.
The formula of the diffusion rate of the cigarette application liquid is the solvent content of the application liquid of the tobacco shreds at the circle center of the cigarette-the solvent content of the application liquid of the tobacco shreds at the set position of the cigarette) divided by (the expected content of the application liquid in the cut tobacco in the formula-the solvent content of the basic cut tobacco sample) multiplied by 100%.
