Post treatment
Steam is generated in the sterilizer through an external
water feed that may be preceded by a softening filter.
Condensation is led off to the drain.
PRE-TREATMENT (1)
The purpose of pre-treatment is to remove air from the
chamber and from the goods. Air prevents the requi-
site contact between the steam and micro-organisms
to be killed.
Pre-treatment consists of steam injection and evacua-
tion pulses in different processes depending on the
program selected. In addition, the humidification es -
sential to killing mainly takes place during the pre-
treatment stage.
STERILISATION (2)
Sterilisation takes place by maintaining the saturated
steam's relation (boiling point at a specific pressure).
The sterilisation phase is in progress during a pre-
programmed number of minutes at the preselected
temperature/pressure.
POST TREATMENT (3)
The purpose of post treatment is to reduce the mois-
ture content in the goods. During post treatment the
pressure drops to atmospheric pressure or lower –
depending on the selected program. Post treatment is
completed by air being drawn in until the chamber is
at atmospheric pressure.
