Abstract

The work demonstrates main principles to improve the convective drying in devices with the weighted layer. Methods for drying process intensification are proposed in the task of the external and internal heat-mass transfer. The possibility to use gravitational shelf dryers to improve the drying efficiency is substantiated. The theoretical results regarding the time, the granule stays in the dryer’s workspace, temperature and humidity properties of the dispersed material under various methods of drying agent’s motion organization are represented.
