In order to demonstrate the validity for aqueous solutions, "Three-Phase Freezing Model" was applied to coffee solutions. The one-dimensional freezing processes of 10, 20, and 40% solutions have been numerically simulated based on the thermo-physical properties as well as the phase diagram obtained by DSC-method, while the freezing experiments were carried out in the similar conditions to those of the simulation. The results showed that the experimental and simulated freezing curves were in good agreement, and that the phase diagram and eutectic temperature of a solution were important for accurate prediction. Then, it is concluded that the freezing model was proved to be applicable in the concentration range of 0-40%.
