PRODUCTION OF HERMETICALLY SEALED PACKAGED FOOD AND MICROWAVE HEATING AND PRESSURIZING STERILIZER

摘要

PURPOSE: To provide a method for producing hermetically sealed and packaged foods in which the target sterilization temperature of the respective foods can rapidly be attained in a stable state without any heating unevenness for each food in the foods filled in a container having plural housing parts capable of housing the respective several kinds of foods different in their heating conditions. ;CONSTITUTION: Foods are passed through a transporting step (B) for feeding at least one hermetically sealed and packaged food package unit 14 onto a conveying line 6, a microwave irradiating step (C) for irradiating the food package 14 with microwaves from waveguides 8 installed on the conveying line 6 under pressurized conditions of 0.5-2.8kg/cm² pressure and increasing the temperature of the food 11 in the package 14 to 100-130°C and a heat-treating step (D) for keeping the temperature under the pressurizing conditions for a prescribed time to produce a thermally sterilized or thermally cooked and sterilized food.;COPYRIGHT: (C)1994,JPO
