A MODIFIED QUASISTATIONARY METHOD OF DESCRIBING THE KINETICS OF DRYING OF HYGROSCOPIC MATERIALS G. I. Efremov UDC 66.047 The article considers the description of the kinetics of drying of hygroscopic materials on the example of wool fiber and grains of corn by a modified quasistationary method obtained in analyzing a diffusion flow in the material. The final relations are rather simple and agree with results of numerical solution of the system of hydrodynamic and heat and mass transfer equations. Satisfactory agreement is obtained between the predicted loss of moisture, rate of the process, and change in temperature with the time of the process and the experimental values.
