ABSTRACT
Drying is often the last separation in a process. Drying refers to removal of water or other solute from solids and often follows evaporation, crystallization, or filtration. Drying is the one of the oldest methods of preservation in the food industry. Drying is often employed to reduce cost of transport, or to have material suitable for handling like in pharmaceutical or soap industries, or in some cases where moisture may cause corrosion.
