Definition of Drying from the PharmacyDictionary.in

Drying

This is a process to remove a liquid (usually water) from the contents of a batch of solid or liquid materials; it involves heat and mass transfer processes such as heat absorption into the substance to be dried, diffusion of the liquid molecules to the surface, vaporization (heat of vaporization must be added), and diffusion into the gaseous phase.
