Title (EN) A UNIT FOR STERILIZING A WEB OF PACKAGING MATERIAL FOR A MACHINE FOR PACKAGING FOOD PRODUCTS
(FR) UNITÉ PERMETTANT DE STÉRILISER UNE BANDE D'UN MATÉRIAU D'EMBALLAGE POUR UNE MACHINE D'EMBALLAGE DE PRODUITS ALIMENTAIRES
Abstract:
(EN) There is described a unit (1, 1', 1", 1"') for sterilizing a web (2) of packaging material for a machine for packaging food products; the unit (1, 1', 1", 1'") comprises a sterilizing chamber (3) containing a sterilizing agent, conveying means (9, 10, 11) for feeding the web (2) through the sterilizing chamber (3) before the web (2) is formed into a succession of sealed packages of food products, a hold tank (16) for the sterilizing agent, feed means (F, 18) which can be activated selectively to feed the sterilizing agent from the tank (16) to the sterilizing chamber (3), drain means (D, 23) which can be activated selectively to drain the sterilizing agent from a bottom portion (8) of the sterilizing chamber (3) into the tank (16) in the event of stoppage of the packaging machine, and a heating device (26) for heating the sterilizing agent before feeding it to the sterilizing chamber (3); the heating device (26) comprises electric heating means (30) and a heat exchanger (31) arranged in contact with the heating means (30) and defining a serpentine- shaped passage (32) for the sterilizing agent.
(FR) La présente invention porte sur une unité (1, 1', 1", 1"') permettant de stériliser une bande (2) d'un matériau d'emballage pour une machine d'emballage de produits alimentaires. L'unité (1, 1', 1", 1"') comprend une chambre de stérilisation (3) contenant un agent de stérilisation, des moyens de transport (9, 10, 11) pour faire avancer la bande à travers la chambre de stérilisation (3) avant que la bande (3) ne soit formée de manière à produire une succession d'emballages scellés de produits alimentaires, un réservoir de stockage (16) pour l'agent de stérilisation, des moyens de fourniture (F, 18) qui peuvent être activés de manière sélective pour alimenter la chambre de stérilisation (3) en agent de stérilisation provenant du réservoir (16), des moyens de vidange (D, 23) qui peuvent être activés de manière sélective pour vidanger l'agent de stérilisation depuis une partie inférieure (8) de la chambre de stérilisation (3) dans le réservoir (16) en cas d'arrêt de la machine d'emballage, et un dispositif de chauffage (26) pour chauffer l'agent de stérilisation avant qu'il ne soit transmis à la chambre de stérilisation (3). Le dispositif de chauffage (26) comprend des moyens de chauffage électrique (30) et un échangeur de chaleur (31) disposé en contact avec les moyens de chauffage (30) et définissant un conduit en forme de serpentin (22) pour l'agent de stérilisation.
