In Industrial drying operations the moisture is removed from a solid, semi-solid or liquid material by using heat. Heat is supplied to the material by the process of conduction, convection and radiation. A small portion of volatile liquid and carrier gas is evaporated by this heat. This evaporated portion passes through the feed material and removes vapor from the medium. Most frequently, drying of material is done by the removal of water into a hot air stream. But drying may also include the elimination of any volatile liquid into any heated gas. The application of drying is found in many fields such as food, pharmaceutical, ceramics, mineral processing, agricultural and chemical industry. Therefore there are several designs of dryer are available to fulfill the demand of each industry.
