Drying is one of the most dominant industrial preservation processes for innumerable products to this day. Industrialization has optimized drying processes, which are conducted under varying, but controlled conditions. Every product requires a specific drying process, which is determined by the type of dryer, the quality of the final product, the extended product shelf life, additional processing, ease of handling, sanitation, cost/energy effectiveness, and investment.

The basic principle of drying has not changed in thousands of years, and the most common dryer type is based on convective drying. In drying technology, the term convective drying is used to indicate when heat and mass transfer are due to the temperature and pressure gradients, respectively, between the drying age ...
