TRANSFER PROCESSES IN POROUS MEDIA

MATHEMATICAL SIMULATION OF THE DRYING OF SUSPENSIONS AND COLLOIDAL SOLUTIONS BY THEIR DEPRESSURIZATION
V. A. Lashkov, E. I. Levashko, and R. G. Safin UDC 674.049;674.048 The heat and mass transfer in the process of drying of high-humidity materials by their depressurization has been investigated. The results of experimental investigation and mathematical simulation of the indicated process are presented. They allow one to determine the regularities of this process and predict the quality of the finished product. A technological scheme and an engineering procedure for calculating the drying of the liquid base of a soap are presented.
