The paper presents a software package for the simulation of the processes of gas flow dynamics and bulk solids drying in vertical fluidized bed systems. The fluidized bed system technology processes, mathematical methods, as well as stages of experiments carried out in the virtual laboratory are described in detail. Fluidized bed behaviors in varied heated air flow rates are described. An algorithm for the operation of the virtual unit is presented including modules containing mathematical models of complex heat transfer systems, gas flow dynamics and control of the drying process, as well as interaction with expandable databases with information on the physical and chemical properties of feed materials, purge gases, and ready-made design solutions. The process of comparing the results obtained in the virtual and real low-temperature simulation models is described.
