What is Drying Mass Transfer operation?

Drying is a mass transfer operation that involves the removal of moisture or other volatile solvents from a solid material. The process of drying is used in a variety of industries, including food processing, pharmaceuticals, chemicals, and textiles.

In drying, heat is applied to the material to increase its temperature, which causes the moisture or solvent to evaporate. The evaporated moisture is then removed from the material using a drying medium, such as air, which carries away the moisture as it flows over the surface of the material.

There are several types of drying techniques, including convection drying, which uses hot air to remove moisture; radiation drying, which uses infrared radiation to heat the material and remove moisture; and vacuum drying, which removes moisture by creating a low-pressure environment.
