For proper sterilization, fill the bottles with approximately the
same amount of liquid.
Nominal parameters default settings
Sterilization temperature: 121
C (250
F).
Sterilization time: 20 minutes.
Operations sequence:
Heating:
Steam enters the chamber and heats it up until the
sterilization temperature is reached.
During the interval of the heating stage, between 100°C and
121°C, the heating rate is kept to approximately a rise of 1 degree
per minute. This will make the last stage of the heating take
approximately 21 minutes. This is to check the durability of the
bottles.
Sterilization:
Sterilization temperature is maintained constant during
the sterilization time.
Cooling:
Forced cooling to the required end temperature, chamber
pressure remains at approx. 300 kPa and the cooling valve is opened.
During the interval of the cooling stage, between 121°C and
100°C the cooling rate is kept to approximately a decrease of 1
degree per minute. This will make the last stage of the cooling
take approximately 21 minutes. This is to check the durability of
the bottles.
Fast Exhaust:
The steam is exhausted out of the chamber at a fast
rate until pressure decreases to ambient pressure.
Drying:
N/A
Ending:
The system checks that End temperature and End pressure
have been reached, and then releases the door.
