Industrial dryers are process equipment designed to remove moisture from a gas or a solid. The following are types of gas dryers; adsorption , desiccant, molecular sieve and refrigerant. The following are types of solids dryers; centrifugal, conical, flash, fluid bed, rotary disc, and spray.

Gas dryers typically require that the gas stream flow through a media that knocksout the moisture or cool the stream so that the moisture condenses and is separated from the gas.

Solids dryers typically blow a dry gas across the solids so that the moisture is transferred from the solids to the gas.
