• To improve or keep the good properties of a material, e.g. Flowability, Compressibility.

• To reduce the cost of transportation of large volume materials (liquids).

Properties of the material being handled: Physical characteristics when wet or dry, Corrosiveness, Toxicity, Flammability, Particle size, Abrasiveness

Drying characteristics of the material: Type of the moisture present (bound, unbound or both), Initial moisture content, Final moisture content (maximum up to which it is to be dried), permissible drying temperature, Probable drying time for different dryers.

flow of material to and from the dryer: Quantity to be handled per hour, Continues or batch operation, Process prior to drying, Process subsequent to drying.

Economic consideration: Value of the materials, Maintenance cost, Labour cost.

Product qualities: Contamination, Uniformity of final moisture content, Decomposition of product, Bulk density.
