The thermal properties of cut tobacco, such as thermal conductivity, thermal diffusivity and volume thermal capacity, are essential to the analysis of heat and mass transfer in various conditions of tobacco processing. The thermal properties of cut tobacco are influenced significantly by processing temperature. In this work, the experimental equipment was established for measuring the thermal properties of cut tobacco under different temperatures. Moreover, the repeatabilities and systematic errors of experimental data were investigated with a transient plane thermal source method at different measuring levels, and the relationship between thermal properties of cut tobacco and temperature were studied. The experimental results are as follows: (1) within the measured temperature range, the change rule of thermal properties of cut tobacco differed at different stages; (2) the standard deviations of repeatability of test results of thermal conductivity, thermal diffusivity and volume thermal capacity of cut tobacco were 0.00583 Wm^-1K^-1, 0.02028 mm²s^-1 and 0.16316 MJm^-3K^-1, respectively; (3) thermal conductivity of cut tobacco significantly linearly correlated to temperature at the first change stage.
