内と被滅菌物１、１とを加熱する。In order to sterilize the objects to be sterilized 1 and 1 by the heat sterilization apparatus configured as described above, first, the objects to be sterilized 1 and 1 are stored in the sterilization container 2 and the sterilization container 2 is sealed. To do. Next, the water supply valve 5 is opened, and water (or a cleaning liquid) is ejected from the nozzles 3 and 3 to clean the objects to be sterilized 1 and 1. Next, the steam supply valve 7 which was closed until then is opened. As a result, the temperature inside the sterilization container 2 rises, and the sterilization container 2
The inside and the objects to be sterilized 1 and 1 are heated.

For example, if the temperature during the sterilization process is too low, the sterilization treatment of the objects to be sterilized 1 and 1 becomes incomplete,
On the contrary, if the temperature is too high, it may cause deformation or rupture of the sterilized objects 1, 1 depending on the type of the sterilized objects 1, 1.

Things cannot be avoided. When the temperature in the sterilization container 2 largely fluctuates in this way, the temperature is set so as to ensure the temperature required for the sterilization process even when the temperature becomes the lowest, so that when the temperature becomes the highest.

は見られなかった。First of all, the steam supply valve 7 is not opened immediately after the temperature inside the sterilization container 2 has dropped below the set temperature, and closed immediately after the temperature has risen above the set temperature. Then, two seconds after the temperature fell below the set temperature, an attempt was made to open the steam feeding valve 7 for one second. However, even by such control, the temperature in the sterilization container 2 largely fluctuates as shown in FIG. 5, and no improvement is seen as compared with the conventional method.

察した。Next, a pressure sensor was installed in the sterilization container 2, and an attempt was made to open and close the steam supply valve 7 based on the pressure in the sterilization container 2 detected by the pressure sensor. That is,
When the pressure in the sterilization container 2 reaches a predetermined pressure or higher, the steam supply valve 7 is closed. On the contrary, when the pressure in the sterilization container 2 becomes a predetermined value or lower, the steam supply valve 7 is closed. The temperature change in the sterilization container 2 was observed based on the control of opening.

Instead, it was found that the temperature in the sterilization container 2 gradually decreased with the passage of time. It is considered that such a temperature decrease is caused by evaporation of drain accumulated in the sterilization container 2, but in any case, it causes sterilization failure and is not preferable.
