Abstract

A mathematical model and method for calculating heat and mass transfer, phase transformations and shrinkage during drying of colloidal porous bodies in the form of a final cylinder are presented. A mathematical simulation of high-temperature drying of willow accompanied by the destruction of hemicellulose was carried out using the data obtained on the values of the activation energy of various types of biomass.
