Abstract: An apparatus is provided for substantially maintaining a position of a plurality of packages (30) between a pair of trays (102 and 104) inside the drum of an agitating retort when the agitation process is applied to the packages. When the first tray (102) is stacked on the second tray (104), a volume formed between the first and second trays. Within the volume, a first positioning system (106) for holding the packages (30) in a desired position is coupled to one of the trays. The packages (30) are positioned within the volume and retained in the desired position by the first positioning system. A second positioning system (114) may be employed to hold the packages at the opposite end of the packages from the first positioning system. The second positioning system (114) may include a resilient pad that grips the adjacent portion of the packages.

Abstract: A retort is described for use with paperboard containers (48) to reduce moisture absorption during processing of foodstuffs therein. The improvement includes using solid cone spray nozzles (50) with spray angles in the range of about 100 degrees to about 115 degrees. In one embodiment, the distance (D?) between the nozzles and the container is in the range of about 70 mm to about 200 mm. In another embodiment, the flow rate if each nozzle (50) is reduced relative to known systems, while the total vessel flow rate is kept the same as per cubic meter load. Further, an overpressure may be added to the vessel via compressed air. In accordance with other aspects, an Impact reduction is used which relates nozzle flow rate, pressure, distance, etc. with moisture absorption in paperboard containers.

Abstract: Described is a method of processing a fiber-based container in a retort vessel that includes subjecting the container to a cooking phase and a cooling phase. During the cooling phase, the difference between the pressure in the vessel and the pressure in the fiber is minimized and kept preferably negative, thereby discouraging moisture ingress in any exposed fibrous surface.
