Bar-shaped cigarette and preparation method thereof

Abstract

The invention discloses a bar-shaped cigarette. The bar-shaped cigarette sequentially comprises a cigarette core material section (1), a cooling section (2) and a filter tip section (4), wherein the cooling section (2) is of a cylindrical bar-shaped structure, grooves (21) extending in the axial direction are formed in the outer wall of the cooling section (2), and openings of the grooves (21) face away from the axial center of the cooling section (2). The invention further discloses a preparation method of the bar-shaped cigarette. The cooling section (2) of the bar-shaped cigarette can effectively reduce the temperature of smoke gas and can further increase the amount of smoke to a certain extent at the same time; the used base materials and liquid additives can be quickly decomposed inthe nature without the risk of environmental pollution; and the loss in the manufacturing process is low, the preparation method is simple, and the manufacturing cost is reduced by more than 30%. In addition, the cooling section (2) can further be used in traditional cigarette filter tips to realize the addition of water-based essence and flavor filter tips.

Description

technical field [0001] The invention belongs to the technical field of heat-not-burn tobacco, and relates to a rod-shaped cigarette and a manufacturing method thereof. Background technique [0002] With the improvement of living standards, people pay more and more attention to their own health problems. In recent years, there has been a lot of attention on smoking health problems. In order to meet the changing consumer demand, major enterprises at home and abroad have developed various completely hollow tobacco products that replace traditional cigarettes. Among these growing fully hollow tobacco products, e-cigarettes and heat-not-burn cigarettes are among the best. [0003] As an expanded application of electronic products in the tobacco industry, e-cigarettes have the advantage of strong variability in taste, and can adjust the smoke flavor by adjusting the components of e-liquid. The taste, especially the sense of heat, is still different from that of traditional cigar...

AI Technical Summary

Problems solved by technology

The problems existing in existing heat-not-burn cigarettes are: 1. Most of the cooling sections are gathered polylactic acid films, and polylactic acid materials are thermoplastic, and are prone to deformation when heated, resulting in the collapse of the cooling section, thereby affecting the effect of the cooling section on the cigarette. Support performance; 2. There is a problem of overheating of the smoke during the smoking process of cigarettes. This is because the cigarettes of heat-not-burn cigarettes are short and the heating temperature is high, resulting in a generally high temperature of the smoke, resulting in "hot cigarettes". mouth phenomenon

Among them, the defect of the first method is that the cost increases more, and the cooling material absorbs heat and collapses to increase the suction resistance, which affects the sensory quality of the smoke; the defect of the second method lies in the processing of the punching equipment and empty pipes in the drilling process. The strength requirement is high, and it brings certain difficulties to the manufacture of the filter tip segment, and the processing cost is high
