型にすることを目的とするものである。[Problems to be Solved by the Invention] Steam sterilization requires high temperature and pressure. As shown in the table of Examples below, the sterilization conditions are, for example, at 140° C., the gauge pressure is 2.7 kg/cm 2 and the required time is 18.9 seconds. Since such high-temperature pressurization is necessary, large-sized pressure vessels are required as first class pressure vessels for the waste liquid sterilization tanks 2a and 2b. Even if the culture tank is small, the waste liquid sterilization tanks 2a and 2b will be large. Further, there are problems such as maintenance of the waste liquid sterilization tanks 2a and 2b as pressure vessels, an excessive installation area, and an increase in equipment costs. The object of the present invention is to downsize a waste liquid sterilization device for a genetically modified organism culture plant.

It is equipped with a steam injector that raises the steam and a retention tube that maintains the waste liquid mixed with heated steam at a sterilization temperature for a required period of time, and continuously sterilizes the waste liquid.

The sterilization process of the waste liquid is completed by keeping it at the sterilization temperature for the required time in the retention tube. In this waste liquid sterilizer, waste liquid is continuously sterilized. Furthermore, since the waste liquid is directly heated by the steam injector, thermal efficiency is high and the device can be made smaller. Furthermore, as the device becomes smaller, the conventional pressure-resistant mechanism is no longer necessary even when high pressure is applied.

The waste liquid flow path 23 that has passed through the preheater 20 is led to a steam injector 24, and in the steam injector 24, heated steam is blown into the waste liquid flow path 23 via a steam valve 26. The waste liquid channel into which heated steam has been blown by the steam injector 24 is led back to the preheater 20 via a retention pipe 28. The waste liquid flow path that has passed through the preheater 20 is led to a drain port via a drain valve 30.

After being preheated, the waste liquid is mixed with heated steam by the steam injector 24, and the temperature of the waste liquid is rapidly raised to a predetermined sterilization temperature. The waste liquid heated by the steam injector 24 is maintained at a sterilization temperature while passing through the retention pipe 28, and is sterilized while passing through the retention pipe 28. The sterilized waste liquid passes through a preheater 20 before being drained, and the preheater 20 is used as a heat source to heat the waste liquid to be sterilized, and is discharged after the temperature of the waste liquid to be drained is lowered.

However, the preheater 20 is not limited to one that utilizes such waste heat, and may be equipped with a separate heat source. Since the retention tube 28 must be kept at the sterilization temperature for the required time, it may be kept warm with a heat insulating material.
