A soft packaging bag to be sterilized by the rotary retort sterilizer 1 is, for example, a standing pouch having a specific gravity of 1 kg or more, preferably 2.5 kg to 5 kg. The material of the soft packaging bag is, for example, a laminate of the first layer (outer layer) polyethylene terephthalate / second layer nylon / third layer aluminum / fourth layer unstretched polypropylene.

What is sterilized is a liquid material such as soup, stew, and curry filled in a vertically long soft packaging bag. The filling is performed with a volume ratio of the head space (space) to the total volume of the sealed soft packaging bag, that is, an air content of 2 to 20.
Is done as is. The headspace is generally air, but may be nitrogen gas or argon gas. More specifically, the air content is, for example, 3 to 20%, preferably 3 to 10%.

When the air content is 2% or less, the ratio of the head space to the volume of the filling is small and the entire filling is not sufficiently stirred during sterilization. On the other hand, the air content is 2
If it is 0% or more, the stirring efficiency of the filling material during sterilization does not increase in proportion to the increase of the air content, and the filling soft packaging bag becomes bulky with respect to the filling material, and the filling soft packaging bag is transported and stored. Is disadvantageous to Furthermore, when the headspace is filled with air, there is a high risk that the filler will oxidize and discolor and deteriorate in quality during sterilization, and when the headspace is filled with an inert gas. It is uneconomical.

In order to uniformly and simultaneously heat-sterilize a plurality of filled soft-wrapping bags by a single pressure-heat sterilization treatment, a variation in the air content of the plurality of filled soft-wrapping bags is set. The porosity is set within -3 to + 50%, preferably within -3 to + 10%. Next, the sterilization operation of the rotary retort sterilizer 1 having the above configuration will be described.

[Hot Water Preparation Step] The valves 310 and 334 are opened and the water supply pump 312 is operated.
A predetermined amount of water is supplied from the water supply source 313 to the hot water tank 3. After the water supply is completed, the valves 310 and 334 are closed and the valve 340 is opened to inject steam from the steam supply source 320 into the water in the hot water tank 3 through the steam supply pipe 256. Adjust the opening / closing of the valves 350 and 354 to adjust the temperature of the water in the hot water tank 3 to 5 to 1 from the planned sterilization temperature.
Make it 0 ° C higher. In this case, the valve 350
It is desirable to prevent the bumping in the hot water tank 3 by adjusting the opening / closing of 354 to adjust the pressure in the hot water tank 3.

[Step of Bringing Filled Soft Packaging Bag into Pressure Heated Sterilization Treatment Tank] The filled soft packaging bag is accommodated in the rectangular accommodation area 240 formed in the tray 206 in a lying state. When the filling soft packaging bag is a standing pouch that can be self-supporting, the filling soft packaging bag is generated due to movement in the tray 206 when the thick pouch bottom is set to be the outer side in the radial direction. It is possible to effectively prevent damage and bag breakage, and it is possible to effectively stir the filling material in the filling soft packaging bag. The thickness of the filling soft packaging bag is equal to or slightly higher than the height of the shroud 232 from the inner bottom surface 230.

Subsequently, the trays 206 are stacked on the carriage 208 in a predetermined level. As a result, the filled soft packaging bag stored in the storage area 240 of the tray 206 is pressed by the bottom surface of the tray 206 in the upper stage. Next, the opening / closing door 224 of the sterilization treatment drum 201 is opened, and a plurality of carts 208 prepared are sequentially loaded into the sterilization treatment drum 201. Then, the trays 206 and the trucks 20 that are stacked
8 is fixed to the rotary frame 203 by the pressing mechanism 214,
The opening / closing door 224 is closed.

[Pressurizing Heat Sterilization Step] Valve 33
4, the valve 316 is opened, the circulation pump 304 is operated, and the hot water in the hot water tank 3 is supplied from the upper water supply / drain port 210 to the sterilization treatment drum 201. The amount of hot water supplied is
It is determined that the rotated tray 206 is always in hot water. As a result, the pressure heat sterilization treatment tank 2 gradually rises in temperature and reaches the sterilization set temperature.

The rotary frame 203 starts rotating when the supply of hot water to the hot water tank 3 is completed. The rotation speed of the rotary frame 203 is
10 to 50 rpm, preferably 20 to 50, although it varies depending on the kind of the filling material, the filling amount, the viscosity, the air content of the filling soft packaging bag, and the like.
It is 30 rpm. Next, the valve 334 and the valve 308
Is closed and the valve 302 is opened, and then the circulation pump 304 is operated to flow hot water from the upper part to the lower part in the sterilization treatment drum 201.

At the same time, the opening / closing of the valve 318 is controlled so that the hot water discharged from the sterilization drum 201 is supplied with the steam 3
Incorporate steam from 20. In this way, the temperature in the sterilization processing drum 201 is controlled so as to become the time temperature curve A shown in FIG. As a method for controlling the temperature in the pressure heat sterilization treatment tank 2, there is, for example, PID control or the like. After the hot water is introduced into the pressure heat sterilization treatment tank 2 until the cooling process is almost completed (time P in FIG. 4), the pressure heat treatment sterilization treatment tank 2 is operated by a pressure sensor (not shown). To detect the pressure.

The temperature in the pressure heat sterilization treatment tank 2 is set to 10
When performing sterilization at 0 ° C. or higher, the valve 326 is set so that the pressure falls within the time pressure region B of FIG. 4, which is set so that the air content of the filled soft packaging bag exceeds 2%. , Opening and closing of the valve 330. As a result, the filled soft packaging bag has a sufficient head space in the filled soft packaging bag until the pressure heat sterilization treatment is almost completed, and the filled soft packaging bag is rotated to fill the filling soft packaging bag with the filling material. Is sufficiently agitated, and it is possible to sterilize with high heat efficiency in a short time, and it is possible to effectively prevent the occurrence of heat sterilization unevenness.

[Cooling Step] The rotation of the sterilization drum 201 is stopped at the time when the pressure heat sterilization is almost completed (time M in FIG. 4). After that, the pressure in the pressure heat sterilization treatment tank 2 is 0.1 to 0.8 k from the pressure during the pressure heat sterilization treatment.
g / square cm, preferably 0.2 to 0.4 kg / square c
The pressure is increased so as to be higher by m (time pressure region C in FIG. 4). Next, the valve 310 is closed and the valve 308 is closed.
Is opened, the hot water in the pressure heat sterilization treatment tank 2 is returned to the hot water tank 3 through the lower water supply / drainage port 212, the valve 302, the circulation pump 304, and the valve 308.

Thereafter, the valve 308 is closed, the valve 310 is opened, and then the water supply pump 312 is operated to pressurize a predetermined amount of cooling water from the lower water supply / drain port 212 via the valve 310 and the valve 302. Water is supplied into the heat sterilization treatment tank 2. After that, after the valve 310 is closed and the valve 316 is opened, the circulation pump 3 is closed.
04 is activated. In this way, the cooling water is caused to flow in the sterilization processing drum 201, and the cooling processing is started. After this, if desired, as shown in FIG. 4, it may be cooled again with fresh low temperature cooling water.

By cooling these, the pressure in the pressure heat sterilization treatment tank 2 is rapidly reduced. The cause is that the gas in the pressure heat sterilization treatment tank 2 is rapidly cooled by the circulation of the cooling water supplied to the pressure heat treatment sterilization treatment tank 2 to reduce the volume thereof, and the pump of the circulation pump 310 is used. It is presumed that this is due to the negative pressure generated by the action. The rapid decrease in the pressure in the pressure heat sterilization treatment tank 2 is detected by the pressure sensor (not shown). If there is such a sudden pressure drop, the rupture of the filled soft packaging bag should occur.

However, in the rotary retort sterilizer 1, as described above, prior to the supply of the cooling water, the pressure in the pressure heat sterilization treatment tank 2 is set to 0.1 to 0.1 times the pressure during the pressure heat sterilization treatment. Since the pressure is increased to be 0.8 kg / square cm higher, even if the pressure in the heat sterilization treatment tank 2 suddenly decreases, the pressure in the pressure heat sterilization treatment tank 2 is kept in the filled soft packaging bag. The height can be maintained so that the bag does not expand and break.

Further, the above-mentioned cooling start (start of circulation of cooling water)
At the same time, the rotary frame 203 is rotated again. The rotation number in this case is 10 to 50 rpm, preferably 2 as in the above.
It is preferably 0 to 30 rpm. After the cooling, that is, the circulation of the cooling water, is started, the pressure of the pressure heat sterilization treatment tank 2 is the time pressure shown in FIG. Within the region D, the air content of the filled soft packaging bag is controlled to exceed 2%. As a result, the filling soft packaging bag can secure a sufficient head space inside the filling soft packaging bag, and as the rotating frame 203 rotates, the filling material is sufficiently agitated in the filling soft packaging bag for a short time. To be cooled efficiently and uniformly.

In the modified example of the present embodiment, in the pressure heat sterilization treatment, in the pressure heat sterilization treatment tank 2 which is predetermined in order to make the air content of the filled soft packaging bag exceed 2%. And a pressure in the pressure heat sterilization treatment tank 2 detected by a means for storing an internal pressure change curve of the filling soft packaging bag corresponding to the time temperature curve of the above, and a means for detecting the pressure in the pressure heat sterilization treatment tank 2. A circuit that calculates the differential pressure from the pressure change curve of the flexible packaging bag,
When the temperature in the pressurized heat sterilization treatment tank 2 is 100 ° C. or higher, the pressurized air supply unit and the exhaust unit are controlled so that the air content of the filled soft packaging bag exceeds 2%, and the above-mentioned differential pressure is adjusted. There is a rotary retort sterilizer including the control means for obtaining the same.
