Problems solved by technology

There are also some so-called electric heating cigarettes suitable for regular size cigarettes (about 8mm in diameter, 50-60mm in length) on the market, but in fact there are only heating devices and no special cigarettes. The smoke produced is often harsh and difficult to swallow

Embodiment 1～5

[0049] According to the formula and process in Table 1, mix guar gum, plant fiber, and metal powder, and perform wet copying molding to obtain a heat-conducting sheet base. In embodiment 1~5, the metal powder that selects is copper powder, and density ρ is 8.9g / m 3 , with a particle size of 8 μm.

Embodiment 10

[0060] The mensuration of embodiment 10 thermal conductivity

[0061] The thermal conductivity of the heat-conducting sheet bases of Examples 1-9, Comparative Examples 1, 2 and 3, the paper base of Comparative Example 4, and several commercially available cigarette sheets for non-burning cigarettes were measured.

[0062] The thermal conductivity is calculated according to the following formula:

[0063] TC=α×ρ×C

[0064] In the formula, TC is the thermal conductivity (w m-1 K-1), α is the thermal diffusivity (m2 s-1), and ρ is the density (kg m -3 ), C is the specific heat capacity (J·kg-1·K-1).

[0065] Measurement of thermal diffusivity α: measured with LFA457 analyzer at 30°C;

[0066] Density ρ: determined by the weight and size of the sample;

Abstract

The invention discloses a shredded tobacco module of a heat-not-burn cigarette and a preparation method thereof. The shredded tobacco module of the heat-not-burn cigarette includes a heat-conducting shredded tobacco structure distributed around the central axis of the shredded tobacco module. The heat-conducting shredded tobacco structure is composed of a heat-conducting sheet base and tobacco thin sheets; The raw materials of the adhesive are wet-processed and overpressed. The heat-not-burn cigarette shredded tobacco module combines the heat-not-burn cigarette base with the tobacco sheet, which can utilize the high thermal conductivity of the heat-conduction film base to transfer heat to the tobacco sheet more quickly and evenly, significantly improving the smoking of heat-not-burn cigarettes. When the aroma concentration and aroma fullness. Moreover, this method is applicable to both central heating and peripheral heating non-burning cigarettes.

Description

technical field [0001] The invention relates to the field of cigarette technology, in particular to a shredded tobacco module of a heat-not-burn cigarette and a preparation method thereof. Background technique [0002] When a cigarette is burned, it will produce a lot of harmful substances, such as: tar, carbon monoxide, etc., which will endanger the health of smokers and the surrounding people in severe cases. Therefore, how to reduce the release of harmful substances in cigarettes is an urgent problem. [0003] Heat-not-burn cigarettes (such as electric heating cigarettes and charcoal heating cigarettes), because the cut tobacco is heated at a lower temperature, the release of harmful substances is significantly lower than that of conventional cigarettes; and this low-temperature cigarette has less sidestream smoke, which is harmful to the environment. The impact is also small. Therefore, this heat-not-burn low-temperature cigarette is sought after by more and more consum...
