Description
Technical Field
The invention belongs to the technical field of detection of heated cigarettes, and particularly relates to a method for stabilizing diffusion rate of applied feed liquid in a heated cigarette.
Background
For enriching smoke or creating heating cigarettes with different styles and tastes, a certain amount of feed liquid is usually applied by adopting a tape casting mode through a feed liquid applying device before tobacco shreds are gathered into a bundle, so that the applied feed liquid is generally at the central position of a tobacco section, and tobacco shreds which are directly contacted with the feed liquid in cigarettes only account for about 10% of the total amount of the tobacco shreds, and the feed liquid needs to be gradually and uniformly spread through natural diffusion of the feed liquid; because the boiling point of the heated cigarette feed liquid is generally higher, the diffusion speed is slower, and if the heated cigarette feed liquid does not reach a uniform state, the stability of the heated cigarette in mouth-by-mouth smoking can be affected.
The diffusion rate of the applied feed liquid in cigarettes has correlation with the composition of the feed liquid, the concentration of the feed liquid, the ambient temperature and the like, but the specific correlation degree is not detected, so that the heated cigarettes are delivered to consumers after being stored for a uniform stock time, and the heated cigarettes are uniformly diffused if not already uniformly diffused, and the stability of the quality of the heated cigarettes cannot be ensured.

Detailed Description
The following examples are given by way of illustration only and are not to be construed as limiting the scope of the invention.
In the process of producing the heated cigarettes, the application liquid is added in the central position before gathering into a bundle so as to achieve the set aim requirement, and when cigarettes of certain brands are produced, the application liquid is always kept unchanged, but the application liquid is different in diffusion rate under different storage temperatures, so that the storage space cannot be better utilized, the change of the temperature is always understood as the change of seasons, because the cigarettes after production are stored in the storage warehouse, the storage warehouse cannot be stored at constant temperature due to space, energy sources and the like, all the warehouses for storing the cigarettes are conventional warehouses and can be changed along with the change of the temperature of the external environment, but when the external environment is summer, the temperature is higher, the diffusion rate of the application liquid is faster, and when winter, the temperature is lower, the diffusion rate is slower, and the change of the temperature exists in spring and autumn, so that the correct storage time is difficult to determine to ensure the stable quality of the heated cigarettes.
Therefore, the method for applying the stable diffusion rate of the feed liquid in the heated cigarettes is provided to ensure that the complete diffusion time of the heated cigarettes is determined even if the storage temperature is changed, so that the quality assurance is ensured, and meanwhile, the warehouse management workload is reduced and the warehouse management is simplified.
Firstly, establishing a diffusion model for applying feed liquid in a heated cigarette, which comprises the following steps:
because the tobacco shred ratios of different brands of heating cigarettes are different, the original flavor, tar content and the like of the heating cigarettes may be different, and therefore, the amounts of the applied liquid materials are different in the different brands of heating cigarettes, namely, the amounts of certain solutes applied are different, so that the designed applied liquid material content in the heating cigarettes of the relevant brands must be determined, so to speak, the content of a certain solute applied to the tobacco shreds of the heating cigarettes after the applied liquid material is uniformly diffused is expected.
The cut tobacco used for producing the formula (the cut tobacco can be prepared from thin slices) is sampled in a random sampling mode, and is used as a basic cut tobacco sample to be sampled and stored in a sealed mode in a set environment.
The obtained basic tobacco shred sample is rolled into a cigarette of the heating cigarette, the rolled cigarette is equally divided into M parts, in the application, M is more than 2 natural numbers, in the embodiment, M is 5, namely the rolled cigarette is divided into 5 parts, and similarly, the applied feed liquid is prepared into 5 applied feed liquids with different concentrations according to different weight percentage concentrations. In other embodiments of the present application, M may be set to be more than 10 parts, for example, 15 parts, 20 parts, or the like as needed, but in consideration of the difficulty in changing the concentration of the applied liquid in actual production, it is determined that the method is not suitable for the classification of the fine material.
The method comprises the steps of filling each concentration of application liquid into the center position of each cigarette by using an injector, specifically, filling each cigarette with the application liquid with the same concentration, then dividing each cigarette into N parts, in the embodiment, selecting N to be divided into 5 parts, namely, in the embodiment, dividing the total into 25 parts of samples, then respectively putting the 5 parts separated from the cigarettes filled with the application liquid with the same concentration into devices with different storage temperatures (in the application, the same humidity is taken as an example for illustration regardless of the influence of humidity), in the embodiment, different temperature distinction can be carried out for different areas, in the embodiment, storage setting days can be selected for-10 ℃, 20 ℃ and 30 ℃, respectively, and detection can be carried out within the range of 3 to 20 days, or any time can be selected for detection.
The specific diffusion rate of the application liquid is determined by detecting the solvent in the application liquid, in this application, propylene glycol or glycerol is used as the solvent, and in this embodiment, glycerol is used as an example.
Taking out any one of cigarettes stored for 5 days, extracting tobacco shreds at a certain position and tobacco shreds at a set position from the cigarettes, and respectively processing the tobacco shreds, wherein in the application, a leaching method is adopted for preparing a calibration liquid for detection, and the specific steps are as follows:
weighing a cut tobacco sample with a set weight, placing the cut tobacco sample in a 500mL beaker, immersing the cut tobacco sample in 300mL of methanol for +/-2 s with the set value, filtering out the cut tobacco sample, shaking up the filtrate, taking 20.0 mu L of 30.0g/L of 1, 3-butanediol internal standard methanol solution, and shaking up the supernatant of the filtrate to 1 mL. The above 10 samples were processed in this way, respectively.

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