A process is provided for minimizing moisture accumulation in a product package that is sprayed with a cool water shower. The product is placed in a container (32), and a closure (36A) is installed on the container (32) to complete the package. The product is heated before it is placed the container (32), or during its placement in the container (32), or after it is placed in the container (32), or while the closure (36A) is being installed on the container (32), or after the closure (36A) has been installed on the container (32). The internal atmosphere within the closed closure (36A) is allowed to expand from the heat and to vent through a vent channel (81A). The package is cooled with a cooling water shower, and the vent channel (81A) minimizes the transient pressure differential so as to minimize the amount of water in filtration into the closure (36A).

La présente invention concerne un processus permettant de minimiser l'accumulation d'humidité dans un emballage de produit qui est pulvérisée avec une douche d'eau de refroidissement. Ce produit est placé dans un récipient (32) et une fermeture (36A) est installée sur ce récipient (32) pour compléter cet emballage. Le produit est chauffé avant d'être placé dans le récipient (32), durant son placement dans le récipient (32), après avoir été placé dans le récipient (32) ou pendant l'installation de la fermeture sur le récipient (32). L'atmosphère interne à l'intérieur de la fermeture fermée (36A) peut se dilater du fait de la chaleur et s'échapper à travers un canal d'évent (81A). Cet emballage est refroidi avec une douche d'eau de refroidissement et, le canal d'évent (81A) minimise le différentiel de pression transitoire afin de minimiser la quantité d'eau en filtration dans la fermeture (36A).
