The number of gas molecules and the volume of the vessel are used as independent arguments in the equation of state. It allows one to use this description in difficult conditions when variability in the number of moles of the structural elements and in the molar volume plays an appreciable role. Application of the kinetic model of the processes in multicomponent mixtures allowed one to determine the area of macroparameters, where mesoscopic properties of large clusters appear in thermal diffusion: thermal diffusion coefficient for them corresponds to liquids.

The relative thermal diffusion coefficient δt was calculated from the obtained moisture sorption isotherm for the seeds of onions. It allowed estimating the contribution of thermal diffusion with respect to the flow of mass conductivity in the considered version of the oscillating IR drying, and it turned out to be 5%. Hence, the thermal diffusion can be ignored for engineering calculations of the kinetics of the oscillating IR drying.
