Notes:
An unsteady-state theoretical analysis of the cooling of a large cross-section ice cream brickette is presented, to model the hardening process required for handling and storage purposes. The material physical properties, i.e. heat conductivity and thermal capacity, are considered temperature dependent, according to available experimental data on a vanilla ice cream. The material is assumed to be macroscopically homogeneous, in the sense that the phase change is simulated by adoption of effective physical properties. The bidimensional differential equations governing the process have been solved numerically using the finite element method, which is extremely powerful for defining optimal design criteria and process control strategies. Results are presented and discussed for different external heat transfer conditions.
