Title (EN) MICROWAVE STERILIZER
(FR) STERILISATEUR A HYPERFREQUENCES
Abstract:
(EN) A roller conveyor (6) for transporting a material to be sterilized is disposed. A heating chamber (3) has doors (8b, 8c) capable of being opened to permit the passage of the material to be sterilized which is transported by the roller conveyor (6). The heating chamber (3) is sealed when the doors (8b, 8c) are closed. Compressed air is introduced into the heating chamber (3) by an air compressor (11) and a microwave is introduced into the heating chamber (3) by a microwave transmitter (15). While a high pressure is kept inside the heating chamber (3), the microwave is applied to the material to be sterilized inside the heating chamber (3). Even then the temperature of the material to be sterilized rises and the pressure also rises due to the irradiation of the microwave, expansion, deformation and breakage of the container can be prevented.
(FR) Un transporteur (6) à rouleaux transporte un produit à stériliser. Une chambre de chauffage (3) possède des portes (8b, 8c) qui s'ouvrent pour livrer passage au produit à stériliser, amené par le transporteur (6) à rouleaux. La chambre de chauffage (3) est hermétique quand les portes (8b, 8c) sont fermées. On introduit de l'air comprimé dans la chambre de chauffage (3) au moyen d'un compresseur (11), et un rayonnement hyperfréquence y est introduit par un émetteur hyperfréquence (15). Tout en maintenant une pression élevée à l'intérieur de la chambre de chauffage (3), on envoie le rayonnement hyperfréquence sur le produit à stériliser qui s'y trouve. Même quand la température de ce produit augmente et que la pression augmente aussi à cause de l'irradiation hyperfréquence, on peut empêcher la dilatation, la déformation et la rupture du récipient.
