CONTINUOUS PROCESS AND SYSTEM FOR PASTEURIZATION OR STERILIZATION OF FOODSTUFFS IN A RIGID CONTAINER FOLLOWED BY ITS DEEP VACUUM CLOSURE BY INJECTION OF ROTARY STEAM
The invention is in the field of vacuum packaging of foodstuffs. It relates to a method, a system of devices for the continuous sterilization or pasteurization of the foodstuffs contained in specific rigid containers, followed by the continuous deep vacuum sealing of said containers, evacuation obtained by rotary injection of steam between the lids and the containers followed by a closing of the containers and a cold shower bringing the condensation of the steam inside the container and consequently a deep vacuum, for a deep vacuum preservation of the food in exceptional organoleptic and nutritive quality conditions, thanks to a drastic reduction in the cooling times of the containers after sterilization or pasteurization, reduction of time obtained by boiling under vacuum at low temperature, boiling distributed homogeneously throughout the container. It is particularly suitable for pasty or liquid products or pieces included in a liquid or pasty device. It imposes the use of an exceptionally rigid container, intended to be closed under a deep vacuum and whose closure is effected by a lid free of attachment means and provided with an elastic seal, lid held only by the vacuum and which can be opened by an empty case system. L'invention est du domaine de l'emballage sous vide de denrées alimentaires. Elle a pour objet une méthode, un système de dispositifs pour la stérilisation ou la pasteurisation en continu des denrées contenues dans des conteneurs rigides spécifiques, suivie de la fermeture sous vide profond en continu des dits conteneurs, mise sous vide obtenue par injection rotative de vapeur entre les couvercles et les récipients suivie d'une fermeture des conteneurs et d'une douche froide amenant la condensation de la vapeur à l'intérieur du conteneur et par voie de conséquence un vide profond, pour une conservation sous vide profond durable des aliments dans des conditions de qualité organoleptique et nutritive exceptionnelles, grâce à une réduction d
