What drying is all about
Drying is a mass transfer process consisting of the removal of water or another solvent by evaporation from a solid, semi-solid or liquid. In the most common case, an air stream applies the heat by convection and carries away the vapor as humidity.
Evaporation is a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance. Two key parts to evaporation are heat and air movement
