Food Extrusion

  • Chapter
Book cover Food Properties and Computer-Aided Engineering of Food Processing Systems

Part of the book series: NATO ASI Series ((NSSE,volume 168))

Abstract

Food extrusion is a versatile process with an expanding variety of applications. Its complicated process environment contributes to scale-up and design difficulties that can be addressed by effective use of computer simulation. This paper reviews the basic physical equations which describe the food extrusion process. These equations define the relevant physical properties necessary for simulations. Next, existing data on viscosity, thermal conductivity, heat capacity, density and friction factors applicable to extrusion processes are summarized along with some of the measurement techniques used and their limitations. A review of computer simulations of food extrusion illustrates its current status and potential as a design tool. Finally, suggestions for future work and collaboration are offered to speed implementation efforts. They are extending the physical property data bank, developing a repository of extrusion data on different sizes of equipment, collaborative development and testing of simulation models, and the formation of a researcher/practitioner user group.
