Method of sterilizing cooling device of foodstuff e.g. meat sauce, involves removing residues of baked foodstuff on outer walls of energy conduit tubes after generation of heating effect, to sterilize tubes

摘要

The method involves inserting the energy conduit tubes (21) into sterilization chamber (51), and injecting steam into sterilization chamber, resulting in rapid temperature difference at outer walls of tubes so as to generate heating effect. The residues of baked foodstuff on outer walls of energy conduit tubes are removed after generation of heating effect, to sterilize tubes. The sterilization of tubes is performed for 3-15 minutes with saturated steam between 115-126 [deg] C.
