The problem of heat treatment of wet materials contains the question of the heat
and mass inside the body transfer (an internal problem) and in the boundary layer at the
interface between phases (an external problem). The amount of removable moisture depends on the degree of each of these processes development. When heated, the moisture
content on the surface decreases, creating a concentration difference across the body.
Therefore, a flow of moisture occurs in the body from deep layers to the surface, towards
which the flow of heat is directed. Thus, when wet materials are heated, complex processes of moisture and heat exchange occur, mutually affecting the enthalpy and moisture
content of both the heated material and the environment.
