Abstract

L'invention concerne un procédé et un dispositif de stérilisation de bouteilles en plastique transportées les unes derrière les autres en position verticale avec leur ouverture dirigée vers le haut. Dans un premier temps, l'intérieur des bouteilles est stérilisé au moyen d'un agent de stérilisation, puis cet agent de stérilisation est éliminé. Pour que des bouteilles en plastique en mouvement continu puissent être stérilisées de manière fiable, le dispositif selon l'invention est caractérisé par des buses (1) de préchauffage et de stérilisation présentant chacune un tube intérieur (2) et au moins un tube extérieur (3), la buse tubulaire formée par le tube intérieur (2) servant à injecter un agent de stérilisation et la buse à interstice annulaire formée par le tube intérieur et le tube extérieur (3) servant à préchauffer les bouteilles avec de l'air chaud. Le dispositif selon l'invention comprend par ailleurs une pluralité de buses tubulaires (5) servant à introduire de l'air de refroidissement, ainsi qu'une pluralité de buses (6) servant à introduire l'air chaud pour le séchage, les buses (1, 5, 6) pouvant être plongées dans les bouteilles.
