This article studies the drying characteristics of granules of hydrophobic polymers. The hydrodynamics of a bed of PET granules has been studied taking into account the process of dust formation. On the basis of the data obtained, restrictions on the velocity gas movement through the granulate bed have been revealed to reduce dust formation at the same time preserving the quality of drying. The refined dependence of the hydraulic resistance of the bed of granules on the velocity of the gas has been obtained.
