The pressure in the tank 2 is detected. When the temperature in the pressurized heat sterilization treatment tank 2 is set to 100 ° C. or higher for sterilization, the pressure is set so that the air content of the filled flexible packaging bag exceeds 2%. The opening and closing of the valve 326 and the valve 330 are controlled so as to enter the pressure region B. As a result, a sufficient head space is secured in the filled soft packaging bag until the pressurized heat sterilization treatment is completed, and the filled soft packaging bag is rotated by rotating the filled flexible packaging bag. Is sufficiently stirred, sterilization can be performed with high heat efficiency in a short time, and generation of heat sterilization unevenness can be effectively prevented.

Water is supplied into the heat sterilization tank 2. After that, the valve 310 is closed and the valve 316 is opened, and then the circulation pump 3 is closed.
Activate 04. Thus, the cooling water is caused to flow in the sterilization processing drum 201 to start the cooling processing. Thereafter, if desired, as shown in FIG. 4, cooling may be performed again with fresh low-temperature cooling water.

発生するはずである。Due to these coolings, the pressure in the pressurized heat sterilization tank 2 rapidly decreases. The reason is that the gas in the pressurized heat sterilization tank 2 is rapidly cooled by the circulation of the cooling water supplied to the pressurized heat sterilization tank 2 to reduce its volume, and in addition to the pump of the circulation pump 310 It is presumed to be due to the negative pressure generated by the action. This sudden decrease in pressure in the pressurized heat sterilization tank 2 is detected by the pressure sensor (not shown). If such a sudden pressure drop occurs, the filled flexible packaging bag should break.

Since the pressure is raised so as to increase by 0.8 kg / square cm, even if the pressure in the heat sterilization treatment tank 2 sharply decreases, the pressure in the pressure heat sterilization treatment tank 2 is increased by the filled soft packaging bag. It can be maintained at a height that does not cause the bag to expand and break.

At the same time, the rotating frame 203 is rotated again. In this case, the number of rotations is 4 to 50 rpm, preferably 15
Desirably, it is 30 rpm. From the start of the cooling, that is, the circulation of the cooling water, to the time when the temperature of the filling material in the filling flexible packaging bag falls to the temperature at the time of filling, the pressure of the pressurized heat sterilization tank 2 is changed to the time pressure shown in FIG. Control is performed so that the air content of the filled flexible packaging bag exceeds 2% while being within the region D. As a result, the filled flexible packaging bag can secure a sufficient head space therein, and the filling material is sufficiently stirred in the filled flexible packaging bag with the rotation of the rotating frame 203.
