The article deals with a study of ammonium nitrate granules structure with nanostructural porous layers, which are obtained after humidification and multistage finish drying. The necessity for an additional stage of granules dehydration in the technology to obtain porous ammonium nitrate is justified. Design of the multistage finish drying phase is represented in the study. The comparative analysis of the granule nanoporous structure after every finish drying stage in thermodynamic and hydrodynamic conditions is shown. The received data is a base to form a technique for an engineering evaluation of the multistage dryers with vertical sectioning of the workspace as a part of installations to obtain 3 D nanostructural layers on the surface of ammonium nitrate granule and inside it.Key words: 3D nanostructural porous layer, Multistage shelf dryer, Crystal structure.
