Abstract

Ce procédé concerne le traitement thermique de produits alimentaires qui contiennent de l'eau ou d'autres éléments susceptibles de s'évaporer lors du traitement thermique et qui sont emballés, de préférence de façon étanche aux gaz, dans une enveloppe faite d'une matière non conductrice, les emballages de produit alimentaire étant exposés au moins à un champ électromagnétique alternatif à haute fréquence alors qu'ils sont immergés dans l'eau. Les emballages sont tout d'abord entourés d'eau de tous côtés, l'eau est ensuite mise sous pression, la pression étant réglée de manière à compenser au moins approximativement, la pression interne qui se manifeste dans l'emballage de produit alimentaire pendant son exposition au champ alternatif, l'exposition au champ alternatif est effectuée jusqu'à ce que soit atteinte la température de traitement et éventuellement de stérilisation prédéterminée pour le produit alimentaire considéré, ainsi que pendant la période consécutive de maintien à la chaleur nécessaire le cas échéant, puis elle est interrompue, et la pression réglée est maintenue pendant l'exposition au champ alternatif, puis est abaissée en fonction de la chute de la pression interne dans l'emballage de produit alimentaire, résultant du refroidissement de cet emballage Le dispositif est un récipient de traitement sous pression pourvu d'électrodes pour l'application du champ et d'orifices pour l'eau.This process relates to the heat treatment of food products which contain water or other elements liable to evaporate during the heat treatment and which are packaged, preferably in a gas-tight manner, in an envelope made of a material. non-conductive, food product packaging being exposed to at least a high frequency alternating electromagnetic field while submerged in water. The packages are first surrounded by water on all sides, the water is then pressurized, the pressure being adjusted so as to at least approximately compensate for the internal pressure which occurs in the packaging of the food product during its exposure to the alternating field, the exposure to the alternating field is carried out until the predetermined treatment and possibly sterilization temperature for the food product in question is reached, as well as during the consecutive period of maintaining the necessary heat if necessary appropriate, then it is interrupted, and the set pressure is maintained during the exposure to the alternating field, then is lowered according to the drop of the internal pressure in the food product packaging, resulting from the cooling of this packaging The device is a pressure treatment vessel provided with electrodes for the application of the field and orifices for the water.
