NUMERICAL SIMULATION OF SUBCOOLING PROCESS FOR BEER FERMENTATION LIQUID

A cooling process for fermentation liquor was modeled and simulated using the Computational Fluid Dynamics (CFD) method. The transient temperature distribution and steam function distribution of fermentation liquid in the tower were obtained from the CFD simulation. The calculated results for temperature field of the fermentation liquor were compared with those from the measuring values during a practical production process. The numerical investigation results revealed the hydrodynamic and energy conditions inside a fermentation jar, which provided a theoretical basis for temperature controlling of beer cooling fermentation process in beer brewery.
