Abstract
(EN) A prepackaged food sterilizing apparatus for sterilizing a prepackaged food P has a high frequency generator 71. A high frequency is supplied from the high frequency generator 71 to the prepackaged food P to sterilize the prepackaged food P by dielectric heating. The apparatus includes a food loading container 2x constituted by a pair of opposing electrodes 20 consisting of a lower electrode 210 and an upper electrode 220 to which the high frequency is supplied and an annular insulator 23 interposed between the opposing electrode pair 20. The food loading container 2x has at least one food loading chamber 21 in which the prepackaged food P is loaded with an inner shape thereof substantially equal to an outer shape of the prepackaged food P.
(FR) La présente invention concerne un dispositif de pasteurisation de produit alimentaire emballé, lequel dispositif comporte un générateur d'ondes haute fréquence (71) qui applique des ondes haute fréquence à un produit alimentaire emballé (P) de façon à pasteuriser le produit alimentaire emballé (P) par un chauffage par induction. Le dispositif comporte en outre un caisson de chargement des produits alimentaires (2x) où des électrodes (20) sont montées face à face. Il s'agit en l'occurrence d'une électrode inférieure (2110) et d'une électrode supérieure (220) entre lesquelles on applique des ondes haute fréquence, un isolant annulaire (23) étant disposé entre les électrodes montées face à face. Le caisson de chargement des produits alimentaires (2x) comporte en outre au moins une chambre de chargement (21) dans laquelle on charge le produit alimentaire emballé (P), laquelle chambre présente, en outre, une forme intérieure épousant généralement la forme extérieure du produit alimentaire emballé (P).
