Experimental studies of the hydrodynamics of flow motion and heat and mass transfer processes in drying units using gravity shelf dryers

Based on the received experimental data, the technique of engineering calculation of shelf dryers with vertical sectioning of working space is improved. An improved design of a multi-stage shelf dryer is proposed, making it possible to separate fine particles on the first perforated contact shelf. The experimental results obtained in this work will be used in the future to perform economic contract work on the provision of information and analytical services for selecting optimal drying schemes and services for the development of design documentation for the design of multi-stage dryers. Together with representatives of Alexander Dubcek University of Trencin (Slovakia), as well as the University of Pardubice and J.E. Purkyne University in Usti nad Labem (Czech Republic) based on theoretical and experimental data, continues to develop a software package for calculating the technological parameters of the gravity shelf dryer and its design dimensions
