Beschrieben werden ein Tunnelpasteur und ein Verfahren zum Pasteurisieren von Getränkegebinden, wobei die Getränkegebinde auf wenigstens zwei übereinander liegenden Decks gefördert und aus jeweils quer zur Förderrichtung der Getränkegebinde verlaufenden Spritzrohren mit einer erhitzten Berieselungsflüssigkeit berieselt werden. Erfindungsgemäß wird die Berieselungsflüssigkeit durch die Spritzrohre des einen Decks in die Spritzrohre des anderen Decks geleitet. Dadurch lässt sich der Wartungsaufwand für das Entfernen von Ablagerungen in schwach durchströmten Abschnitten der Spritzrohre reduzieren.The pasteurization tunnel (1) comprises two decks (2, 3) that are arranged on one another. A conveyor transfers beverage packs (4). A set of spraying pipes (5, 6) provided with nozzles (7) for spraying the beverage packs, where the spraying pipes extend transversely to a conveying direction of the conveyors. The spraying pipes of the first deck is connected in series with the spraying pipes of the second deck to guide a spraying liquid through the first deck to the second deck, where the conduit cross-section of the spraying pipes is larger in the first deck than in the second deck.
