Description

TECHNICAL FIELD

[0001] The application relates to the technical field of tobacco detection, and in particular to a portable heating cigarette temperature and humidity adjusting and transferring device. BACKGROUND

[0002] In recent years, heating cigarettes have developed rapidly. As of the end of 2020, IQOS cigarettes were sold for 76.11 billion, have been marketed in 64 countries and regions around the world, and have 17.6 million users. Heating cigarettes are a new type of tobacco product that releases aerosol through heating distillation (below 500 DEG C).

[0003] The materials and processes of heating cigarettes and traditional cigarettes are different, and their moisture absorption capacities also have great differences, and the degree of influence of the relative humidity of the environment is also different.

[0004] Li Chaojian et al. (Li Chaojian, Liu Xianjun, Zhuang Yadong, et al. Detection of mainstream cigarette smoke moisture and analysis of influencing factors [C] / / China Tobacco Society Annual Conference Excellent Papers. Beijing: China Tobacco Society, 2017.) found that when the relative humidity of the environment is 40% to 60%, after being stored for 96 hours, it not only has an impact on the stability of the reconstituted tobacco structure, but also has an impact on the moisture release amount of smoke, the glycerol release amount of smoke, the nicotine release amount of smoke, and the mass of particulate matter in smoke.

[0005] In addition, there are few existing studies on the influence of the relative humidity of the environment on the moisture, physical properties, smoke properties, and sensory indicators of heating cigarettes. In particular, there is a lack of research on the most suitable relative humidity conditions and storage time for heating cigarette production workshops and the influence of the conditions on the quality of heating cigarettes.

[0006] Due to the change in environmental humidity in different seasons, the moisture content of heating cigarettes will also change during processing and transportation. The moisture content of cigarettes is closely related to the quality of cigarettes.

[0007] When the environmental humidity is low, the moisture of the cigarettes will gradually be lost, resulting in an increase in the dryness of the heating cigarettes and an increase in the irritation. When the environmental humidity is high, the cigarettes are prone to be damp, resulting in changes in the sensory indicators such as the appearance quality, smoke volume, strength, and aroma state of the cigarettes, and even mold growth of the cigarettes.

[0008] Shi Jianyang et al. (Shi Jianyang, Guo Linqing, Liang Kun, et al. The influence of environmental relative humidity on key indicators of dry reconstituted tobacco for heat-not-burn cigarettes [J]. Tobacco Science and Technology, 2022, 55(2): 84-90.) found that heat-not-burn cigarette products stored at different environmental relative humidities had significant changes in the moisture content of the smoking segment, draw resistance, smoke composition (nicotine, total particulate matter, and moisture), and sensory indicators: ① The moisture content of the smoking segment, draw resistance, total particulate matter, and smoke moisture were positively correlated with relative humidity; ② Environmental relative humidity had no significant effect on the circumference and roundness of the cigarette during the experiment, but was negatively correlated with the release of smoke nicotine; ③ Lower relative humidity would lead to increased irritation of heat-not-burn cigarettes; while higher relative humidity would result in reduced smoke volume, sparse aroma, and a burning mouthfeel; ④ Unlike traditional cigarettes, which require 60% relative humidity, when the temperature is (25±2)℃, 43% relative humidity is more suitable for the production and storage of heat-not-burn cigarettes.

[0009] In short, high-humidity environments are not conducive to the storage of heat-not-burn cigarettes and have a significant impact on product quality and consumer experience. The hygroscopic nature of heat-not-burn cigarettes often leads to reduced smoke volume, sparse aroma, and a burning mouthfeel, which severely affects the quality of heat-not-burn products.

[0010] There is no dedicated storage device for heat-not-burn cigarette samples in the prior art. Currently, heat-not-burn cigarette sensory evaluation samples are usually adjusted for temperature and humidity in the laboratory according to relevant requirements before sensory evaluation. Typically, the location for sensory evaluation is not in the same laboratory as the sample adjustment, and the samples that have completed temperature and humidity adjustment need to be re-stored and transferred. The samples are usually stored in plastic self-sealing bags, plastic boxes, or aluminum boxes as shown in Figure 1 This can easily cause the samples to be damaged due to pressure deformation, or the tobacco filler in the cigarette to fall out due to shaking, affecting the quality of the cigarette, and hygroscopicity affecting the sensory quality.

[0011] There is a lack of devices that can maintain constant temperature and humidity conditions during the detection and sensory evaluation of heat-not-burn cigarettes after they are prepared in the laboratory to avoid environmental influences on the sensory evaluation results of heat-not-burn cigarettes.
