The freezing curve of the food material was extracted from Differential Scanning Calorimetry experiments. A heat conductive model was generated in COMSOL, including the thermo-physical characteristics and the phase transition behavior. The resulting temperature-time evolutions at different positions in space were in excellent agreement with our experimental data. Changing scale, the variation of micro-ice crystals size with time and temperature was approached.
