Abstract


In this paper, the authors presented the results of the study of the convective drying kinetics of various types of natural leather in a free state using heated air when changing the regime parameters of drying in a wide range. The results of processing experimental data using stable generalized variables for the drying process are presented. The article provides approximate experimental equations for determining the duration of drying, the density of heat fluxes, the intensity of evaporation of moisture, the temperature in the period of the falling drying rate. Also, the authors detected a relationship between the complex variables of the drying process. The proposed method for calculating the kinetics of drying of leathers allows one to determine with sufficient accuracy all the main kinetic characteristics of the drying process. For the purpose of the analysis, the validity of the obtained equations was verified and the experimental and calculated values of the parameters were compared using the obtained equations.
