Abstract
This work substantiates the possibility to control the quality of nanostructured porous layers in porous ammonium nitrate (PAN) granules by introducing an additional stage of final drying and choosing the optimal thermodynamic conditions for this process. The necessity of the final drying stage in the PAN production technology is validated. An algorithm for calculating the thermodynamic parameters of the drying unit is presented. The results of studying the morphology of PAN granules with various diameters, obtained in a gravitational shelf dryer, are demonstrated. The results from study of the thermodynamic conditions for the implementation of the PAN final drying stage will be included in the methodology for the technological calculation of the granulation-drying unit.
