Title
(EN) Packed food pasteurizing device and pasteurizing method
Abstract
(EN)

A prepackaged food sterilizing apparatus for sterilizing a prepackaged food P has a high frequency generator71. A high frequency is supplied from the high frequency generator71to the prepackaged food P to sterilize the prepackaged food P by dielectric heating. The apparatus includes a food loading container2xconstituted by a pair of opposing electrodes20consisting of a lower electrode210and an upper electrode220to which the high frequency is supplied and an annular insulator23interposed between the opposing electrode pair20. The food loading container2xhas at least one food loading chamber21in which the prepackaged food P is loaded with an inner shape thereof substantially equal to an outer shape of the prepackaged food P.
