DEVICE FOR THERMALLY STERILIZING PACKED FOOD AND METHOD FOR THERMALLY STERILIZING

摘要

PROBLEM TO BE SOLVED: To provide a device for thermally sterilizing packed foods, which can ensure a sure sterilization treatment and reduce an energy cost required for the sterilization. SOLUTION: This device for thermally sterilizing packed foods, in which high frequency waves are applied to packed foods F disposed between the insides of electrodes disposed in a mutually facing state to subject the packed foods F to a thermal sterilization treatment, characterized by disposing laying members 17 formed from a heat-insulating material, an elastic material or a dielectrically heatable material on the inside of at least one of the electrode plates 13, 14.
