Description
Technical Field
[0001] The utility model belongs to the technical field of tobacco, and relates to smoke treatment, in particular to a structure for reducing cigarette smoke temperature and increasing aroma. Background Art
[0002] Consumers enjoy the aroma of cigarettes by burning and smoking. For cigarette consumers, they not only require that the harmfulness of cigarettes is as low as possible, but also require that cigarettes have high-quality smoking taste, bringing pleasant and comfortable smell and taste feelings. The aroma components of tobacco are an important component of the flavor of cigarette products and an important factor in evaluating the quality of cigarettes. However, with the improvement of people's safety awareness, cigarette materials must also change towards safety and environmental protection. Under the general situation of reducing tar and reducing harm, it is inevitable that there will be problems such as insufficient aroma and poor consumer experience. To this end, people have taken a lot of improvement measures, such as flavoring tobacco materials and tobacco shreds. Common cigarette material aroma-carrying technologies include mid-line aroma-carrying, bursting bead aroma-carrying, molding agent aroma-carrying, corking paper aroma-carrying and particle aroma-carrying. Among them, bursting bead aroma-carrying is currently the best solution for aroma-carrying and aroma-retaining effects. Consumers squeeze the capsule to release the flavor when smoking, but due to the influence of industry policies and use costs, the development of bursting bead cigarettes is restricted, which leads to more attention for other types of cigarette-carrying materials. Particle aroma technology is currently the most widely studied aroma technology. In order to improve the aroma retention effect of particles, porous materials with strong adsorption (such as activated carbon, molecular sieves, etc.) are currently used as aroma substrates; although these materials have strong adsorption, they generally contain impurities, which seriously affects the sensory taste of smoke. At the same time, heated cigarettes are developing rapidly, and their smoke cooling is a key technical issue. In view of the demand for heated cigarettes and the current problems with aroma enhancement, it is objectively necessary to develop new aroma enhancement structures. Utility Model Content
