ABSTRACT

Infrared (IR) radiation heating operation is relevant to many industrial heating and drying processes because it can achieve rapid and contactless heating. Specific advantages of IR heating compared with conduction and convection heating are as follows: reduced heating time, uniform heating, reduced quality losses, absence of solute migration in material, versatility, simplicity, compact equipment, and energy saving (Krishnamurthy et al., 2008). In recent years, IR heating has also been applied to disinfection of food and agricultural produce (Hamanaka et al., 2006).
