Review of Some Thermal Methods in Drying and Roasting Processes

Toktam Mohammadi-Moghaddam, Mohammad Morshedi, Ramina Moalemzadeh Ansari, Afsaneh Morshedi and Marcos Eduardo Valdes Thermal processing is a routine procedure in food science, with two important methods being drying and roasting. During thermal processing, simultaneous heat and mass transfer occur, where the distribution of heat and humidity depends on effective diffusivity. Various methods exist for achieving this, each differing in efficiency and energy consumption.
