ABSTRACT:
The sterilization of reusable kegs in which a consumable beverage is dispensed includes pressurization of the keg with steam, measuring the residual pressure after a time delay which may vary, and comparing the residual pressure against a standard pressure read from a cooling curve which plots pressure decay vs. time delay. A family of standard cooling curves will be stored for each type keg to be sterilized with the curves for each keg being a function of the difference between the steam and ambient temperatures.
