INFLUENCE OF ANOMALIES IN TUNEL PAZTEURIZER ON THE QUALITY OF PACKAGED BEER

Abstract

Introduction:
The quality of beer packaged in bottles depends to a large extent on the conditions under which the pasteurization stage takes place in a tunnel, with the inlet temperature of the beer as well as the water temperatures in the different zones being the main
variables that influence the pasteurization units.
Objective:
Study the behavior of the beer inlet temperature as well as the water temperature in the different zones of a tunnel pasteurizer under anomalous conditions, through modeling and simulation with the COMSOL software, for the analysis of its influence on the units of pasteurization.
Materials and Methods:
The system to be modeled is formed by the bottle that contains the beer to be pasteurized, which passes through the zones of a tunnel, and the water that is supplied through the showers arranged in each zone for this purpose.
Results and Discussion:
Four variants are studied, starting from a base case with changes in the variables of beer inlet temperature, and water temperature in the different zones, analyzing in each case the incidence in the pasteurization units.
Conclusions:
Values of pasteurization units higher than those reported in the literature can be seen for each anomaly studied.
