ABSTRACT

The flow of moisture inside a food material during the

course of a drying operation or addition of moisture is a

very important problem in the agricultural engineering

industry. Food materials have a porous structure, and the

flow of the fluid (different components of the moisture

transfer in liquid and vapor forms) inside the food is gov-

erned with the basic conservation laws of mass, momen-

tum, and energy.[1] Different physical phenomena occur

simultaneously when a food sample is being dried. There is

a transfer of fluid inside the food material along with a

concurrent transfer of vapor inside the food, making the

actual problem a multiphase transport problem.
