A two-way evaporation of liquids from conical channels has been studied . The influence of the temperature gradient on the mass transfer process has been considered. An approximation expression for the temperature coefficient of evaporation has been derived and algorithm for calculating the system drainage time is developed. The double-sided vaporization from conical channels at an axial temperature gradient has been investigated in detail. Expressions for temperature coefficient of evaporation has been obtained and a computational algorithm for vaporization velocity has been developed. The obtained results allow estimating the duration of drying for materials with through pores of any type under conditions of uneven heating.
