ABSTRACT:
Packaged foodstuffs are cooked by introducing them into a pressure retort comprising a cylindrical vessel closed at one end and provided at its other end with a closure movable between open and closed positions. Within the vessel is a hollow housing having longitudinally extending walls defining therebetween a cooking chamber and forming passages between the housing and the vessel, the housing having at one end a transverse partition confronting end spaced from the closed end of the vessel to provide a compartment between the housing and the closed end of the vessel. The cooking chamber is adapted to accommodate foodstuffs carried by supports such as carts. Cooking is accomplished by introducing steam or hot water into the cooking chamber and maintaining therein an elevated temperature for the time necessary to cook the foodstuffs. Substantially uniform cooking temperature is maintained throughout the cooking chamber by discharging the steam or hot water from one end of the cooking chamber through an opening in the partition into the compartment, and then reintroducing such steam or hot water to the opposite end of the cooking chamber via passages. The circulation of the steam or hot water is effected by a rotary impeller mounted in the opening of the partition.
