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.
