なかった。In order to pressurize the saturated steam, it is necessary to use a pressure resistant chamber or the like, but it is difficult to continuously supply the substance to be sterilized into the pressure resistant chamber. Therefore, the sterilization treatment should be continuously performed. I couldn't. Further, when the object to be sterilized is heated in the pressure resistant chamber, the object to be sterilized contains water, and it is necessary to dry the object to be sterilized after taking out the object to be sterilized from the pressure resistant chamber. There wasn't.

In addition, the effect of the presence or absence of ultraviolet irradiation was investigated. Furthermore, as described above, the level of the jet outlet is 2
Case 1 is at 0 mm upper level, case 2 is when the lower end of the nozzle is inserted into the container and the level of the ejection port is 20 mm lower than the upper end of the container, and in both cases the nozzle is The influence of the positional relationship of the containers was investigated. The test results are shown in Table 1.

Further, when the injection time is 6 seconds or longer, a sterilizing effect of 6 or higher is obtained. This means that all the test bacteria attached to the blank were killed. It was generally said that the only way to sterilize Aspergillus niger was to use chemicals.
Being able to kill a niger is a great advantage.
