Numerical Simulation of Liquid Food Sterilization in a Still Can

摘要

Cylindrical liquid can of water and CMC was simulated by solving the governing equations for continuity, momentum and energy conservation, using "COMSOLR" multiphysical coupling field software package which based on finite element method of analysis. Through finding out cold spot of 100°C, 105°C, 110°C and 115°C in the can and sterilization minimum value spot, temperature and sterilization value were compared. The results indicated that there were differences between cold spot and F minimum value spot. Thus, in order to ensuring food safety, the original sterilization time should be moderately prolong, especially for thinly-fluid.
