Abstract
L'invention concerne un procédé de décongélation de denrées alimentaires se présentant sous la forme de grosses pièces. Ce procédé consiste à disposer la ou les pièces dans une chambre froide blindée, à assurer une circulation d'air froid à une température inférieure à -10 degrés C, et à irradier chaque pièce par des ondes hyperfréquences de fréquence comprise entre 300 et 2 000 mégahertz au moyen d'au moins un applicateur hyperfréquence orienté vers ladite pièce qui, de préférence, est amenée à tourner sur elle-même. Le procédé de l'invention permet de décongeler de grosses pièces, notamment de masse supérieure à environ 30 kilogrammes.
