4.11. DRYING
This phase of the sterilization cycle allows eliminating the residual humidity from the chamber, by completely drying
the load.
The drying is carried out keeping a negative pressure level inside the chamber and allows the condensate to
evaporate also at a temperature lower than 100°C.
During the drying phase, which requires a specific time for each sterilization cycle (e.g.: 12’ for 134°C universal cycle)
a series of pressure pulses are performed in the chamber, indicatively between - 0.80 bar and 0.60 bar, to improve
the removal of the residual steam; the number of pulses performed can vary according to the humidity level in the
load.
In the pressure rise phases carried out during pulses, solenoid valve EV5 is activated to allow the air to flow inside
the chamber through the bacteriological filter; this air flow helps removing steam.
