METHOD AND TREATMENT STATION FOR HEATING AND STERILIZING KEGS, IN PARTICULAR REUSEABLE KEGS

摘要

A pressurized phase for vapor treating a reusable metal keg includes filling the keg with pressurized water vapor through an inlet and then interrupting the connection, thus initiating a dwell time. During this dwell time, condensate forms on the inner surfaces of the keg. Meanwhile, one causes relative movement between the water vapor and the keg's inner walls.
