Abstract
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, and a closure is installed on a container. The product is heated before it is placed in the container or during its placement in the container, or after it is placed in the container, or while the closure is being installed on the container, or after the closure has been installed on the container. The internal atmosphere within the closed closure is allowed to expand from the heat and to vent through a vent channel. The package is cooled with a cooling water shower, and the vent channel minimizes the transient pressure differential so as to minimize the amount of water infiltration into the closure.
