Mathematical Modeling of Food Freezing in Air-Blast Freezer

Guiqiang Wang and Pinghua Zou
Abstract—A mathematical model for simulating the heat transfer during food freezing was presented. The model consists of three steps. First, the flow field inside the freezing chamber was modeled using the CFD method, based on which the freezing condition, including the temperature and velocity around the food, was calculated. Second, the heat transfer coefficient between food and air was calculated in the CFD model. Third, a finite-difference model was employed to simulate the heat transfer inside the food product. Measurements were conducted on different food products in freezing chamber to verify the mathematical model. The effects of process parameters on food freezing were also analyzed, which concludes that the air temperature has more influence on food freezing than the air velocity.

Index Terms—Air-blast freezer, food freezing, package.
