Abstract
The drying process under conditions of filtration of a drying agent through a porous structure of a moist article is considered. The existence of three dehydration stages is established: 1) mechanical displacement of water; 2) elimination of moisture in the form of a gas-liquid emulsion; 3) drying. A kinetics equation is derived for each stage. Combination of all the three stages provides a high rate of the total process exceeding the drying rate by tens of times when flowing around an object as a unit.
