Program 13: Air Mixture
This program is intended for liquids in soft packages when the
manufacturer recommends autoclaving at temperature of 121ºC
(250
F) for 15 minutes.
Sterilization is controlled in a way that the sterilization pressure
remains approx. 30% above the theoretical pressure corresponding to
the same temperature according to the steam table. These intends for
prevent swelling or warping of the package.
Cautions!
Both PT100 temperature sensors must be inside the bottles.
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: 15 minutes.
Operations sequence:
•
Heating:
Air enters the chamber followed by steam that heats it up
until the sterilization temperature is reached. Air adds pressure
needed to prevent swelling or warping of soft plastic items
.
Chamber
fan is used to mix air with steam.
•
Sterilization:
Sterilization is controlled in a way that the sterilization
pressure remains approx. 30% above the theoretical pressure
corresponding to the same temperature according to the steam table.
•
Cooling:
Forced cooling to the required end temperature, chamber
pressure remains at approx. 300 kPa and the cooling valve is opened.
