In this article, the process of heat exchange between granular-fibrous materials in a pseudo-liquefied layer formed by the flow of liquid or gas is scientifically and technically covered. Based on the temperature difference between heat carriers (hot water, steam, gas) and materials, the efficiency of this process is ensured by the free movement of the heat carrier in the layer, the expansion of surfaces, as well as intensive convection. The focus is on parameters such as heat transfer coefficient, temperature gradient, heat capacity of the material and flow rate. The possibilities of process analysis through mathematical modeling (Fourier, Navy-Stokes equations) and experimental methods are also considered.
