The work is devoted to developing a technological package "drying unit" using a multistage gravitational dryer as the main equipment. The study aims to create a workable sample of a drying module and propose an algorithm for its industrial implementation. The work uses methods of analysis and synthesis, search for cause-and-effect relationships, theoretical and computer modeling, and experimental studies. The description of the main stages of drying granular materials in a multistage gravitational shelf dryer is given. The tools of influence of the design features of the dryer on the nature of the flow of each stage of the drying process are shown. A variant of the technological scheme of the drying unit and the scheme of automation of the drying process are presented. A set of solutions is proposed for monitoring the technological level of readiness of the "drying plant" package for industrial implementation. Based on the Ishikawa diagram, the directions for improving the quality of the drying process, improving the drying unit, and the multistage dryer are analyzed. A marketing strategy for the transfer of drying technology using a multistage dryer is described. The result of the study is a roadmap for developing and implementing a drying module using devices with active hydrodynamic modes.
