PROBLEM TO BE SOLVED: To prevent rotting during the preservation by a method wherein an object to be sterilized is heated up to the temperature of sterilization, then, packed into a high pressure tank to be maintained at the temperature of sterilization and held being oscillated for a specified time length so that the object to be sterilized and the entire inside of a container are sterilized and taken out to accomplish high temperature sterilization without degraded quality. SOLUTION: When a conveying device 5 moving intermittently in a high pressure tank A is stopped intermittently, an object to be sterilized with the temperature above 100 deg.C is packed being kept at a high temperature into a container of a retainer 4 from a filling device 1 and then, the container is closed and sealed up by a cap closing device 8. While being kept at a high temperature, the object is intermittently transferred at an oscillating part 9 in a high pressure gas phase part by the conveying device 5 for a specified time length thereby sterilizing the entire inside of the container together with the object to be sterilized. Thereafter, the container is transferred intermittently to a cooling tank 2 for cooling to be transferred again to the high pressure gas part and taken out by a container takeoff device 7. This enables extermination of bacteria without prolifration thereof. |
