Description
Technical Field
The invention belongs to the technical field of detection of heated cigarettes, and particularly relates to a method for establishing a diffusion model of a material liquid applied in a heated cigarette.
Background
With the rise of new tobacco in recent years, due to the lower hazard of the new tobacco, the new tobacco is gradually accepted by consumers in recent years, and especially a few consumers in foreign countries, and the heated cigarettes rapidly become new consumption hot spots in the cigarette market.
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.
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 above sampled base tobacco is rolled into a heated cigarette, and the rolled cigarette is equally divided into two parts, wherein the even number is calculated without considering the case that the number of rolled cigarettes is odd, and in fact, when the odd number of cigarettes is rolled, it is the most common practice to discard one piece of cigarettes.
The first portion of the tobacco rod is then equally divided into M parts, where M is a natural number greater than 2, in this embodiment, M is schematically indicated as 5, that is, in the following description, the first portion of the tobacco rod is equally divided into 5 parts, then the applied liquid is adjusted to different weight percentage concentrations (here, based on one of a certain essence, perfume or essential oil of cigarettes) by using a syringe, in this application, description is given by taking ethyl propionate as an example, wherein glycerol is used as a solvent, in this application, the weight percentage concentrations of ethyl propionate in the applied liquid are respectively 10%, 13%, 16%, 19%, 21%, and the different amounts of filling are respectively, but the content of ethyl propionate on tobacco shreds after the added applied liquid is generally ensured to be uniform by diffusion is the same, the applied liquid of the 5 weight percentage concentrations is respectively added to the 5 parts of tobacco rod, and the above-mentioned tobacco rods after the applied liquid is respectively stored at the same set temperature in this embodiment at the set temperature of 25 ℃.
Similarly, the second portion of the cigarettes is equally divided into N parts, where N is a natural number greater than 2, in this embodiment, N is schematically indicated as 5, that is, in the following description, the second portion of the cigarettes is equally divided into 5 parts, then any one of the application solutions prepared during the description of the first portion is selected to be used by using a syringe, in this embodiment, the application solution with the concentration of 13% by weight of ethyl propionate in the application solution is selected to be described, the above 5 parts of cigarettes are filled with the application solution with the concentration, and then the 5 parts of cigarettes are respectively stored in environments with different temperatures, where the influence of humidity on the technical scheme is not considered, including the treatment of the first portion of cigarettes, that is, the technical scheme is all performed under the same humidity condition.
