ABSTRACT
The physical processes and unit operations of process engineering are based on the transport phenomena of momentum, heat, and mass (Bird et al., I 960; Geankoplis, 1993). The transport phenomena, originally developed in chemical engineering, can be applied to the processes and unit operations of food engineering (Gekas, 1992). The analogy of momentum, heat and mass transport facilitates a unified mathematical treatment of the three fundamental transport processes (Brodkey and Hershey, 1988).
