Modeling and process simulation of a single screw food extruder

This paper presents the design of a model for simulation of a food extruder. The model has been obtained from the energy mathematical model and experimental data of a real extruder. Some process variables having no relation with the energy model have been added to the model. Experimental results show information about extruder performance when some controlled, manipulates and additional variables are modified. The simulations carried out can be used to improve the extrusion process and to obtain initial relations between process and product variables in order to produce new products in an easier and economical manner.
