4.6 Program 6 (6 – liq+Cool)
For materials when the manufacturer recommends processing at
temperatures of 121ºC and cooling to temperatures of 85ºC with no drying
cycle.
Nominal Parameters
Sterilization temperature: 121ºC
Sterilization time: 30 minutes.
Operations Sequence
Heating phase; The water enters the chamber and heats up until the
sterilization temperature is reached.
Sterilization phase; temperature is maintained constant at the preset
level for the sterilization time.
Forced cooling to 85ºC, while the pressure in the chamber remains the
same as the sterilization pressure, by supplying compressed air into
the chamber. The forced cooling shortens the cooling stage
significantly.
Slow exhaust phase (Ex. Mode=5); until the pressure equals the
atmospheric pressure.
