The laws of internal mass transfer under deep drying of 
granular polymers depending on their state have been considered. From 
the point of view of the system approach, the general problem of their 
drying kinetics has been decomposed into two basic levels: a micro- 
and a macroscopic one, and, in accordance with this, the questions 
of mathematical modeling have been analyzed. The experimental data 
on the diffusion and sorption properties and longitudinal mixing of 
the solid phase are presented and recommendations on the apparatus 
arrangement of the process are given.
