Abstract

The thermophysical properties of tobacco and smoke agent (the mass ratio of glycerol and propylene glycol is 51) was measured by transient plane heat source method, and the effects of moisture and smoke agent content on reconstituted cut tobacco and flue-cured were measured. The results showed that with the increase of temperature (22~75 ℃), thermal conductivity \[0.06~0.12 W/(m·K) and 0.06~0.16 W/(m·K\] and volume heat capacity \[0.17~2.70 MJ/(m3K) and 0.15~1.45 MJ/(m3K)\] increased; however, the thermal diffusivity decreased (0.33~0.05 mm2 / s and 0.40~0.09 mm2 / s, respectively). With the increase of moisture content (0%~13%) , the thermal conductivity and the volume heat capacity of tobacco materials increased, however, the thermal diffusivity decreased. With the increase of smoke agent content (0%~25%), the thermal conductivity of tobacco material \[0.005 W/(m·K) and 0.006 W/(m·K)\], the volume heat \[0.106 MJ/(m3K) and 0.138 MJ/(m3K)\] increased slightly, but the thermal diffusivity decreased ( 0.069 mm2 / s and 0.069 mm2 / s, respectively).
