A proofing cycle consists of 5 phases with different temperatures, relative humidity, fan speeds and durations, one
following on from the other, as in the sequence described below.
8.8.1.1
BLOCKING phase
Temperature regulation is active and has a neutral zone adjustment, the temperature setpoint, the fan speed and
duration in hours and minutes for the phase are set by the end-user. This phase does not include humidity control.
8.8.1.2
CONSERVATION phase
Temperature regulation is active and has a neutral zone adjustment, the temperature setpoint and the fan speed are
set by the end-user. This phase does not include humidity control.
Moving from the blocking setpoint (previous phase) to the conservation setpoint can be gradual, with the incremental
percentages set while the parameters are being set.
The duration of this phase is calculated automatically by the controller on the basis of the duration of the blocking, re-
awakening and proofing phases and the day and time for the end of proofing required for the dough.
8.8.1.3
RE-AWAKENING phase
Temperature regulation is active and has a NEUTRAL ZONE adjustment, the working setpoint is set by the end-user.
Moving from the conservation setpoint (previous phase) to the re-awakening setpoint can be gradual, with the
incremental percentages set while the parameters are being set.
Relative humidity regulation is active and has a NEUTRAL ZONE adjustment, the working setpoint is set by the end-
user.
The duration in hours and minutes and the evaporator fan speed are set by the end-user.
8.8.1.4
PROOFING phase
Temperature regulation is active and has a NEUTRAL ZONE adjustment, the working setpoint is set by the end-user.
Moving from the re-awakening setpoint (previous phase) to the proofing setpoint can be gradual, with the incremental
percentages set while the parameters are being set.
Relative humidity regulation is active and has a NEUTRAL ZONE adjustment, the working setpoint is set by the end-
user.
The duration in hours and minutes and the evaporator fan speed are set by the end-user.
8.8.1.5
BAKING DELAY phase
The baking delay is always enabled but can be disabled, either when the cycle is being set up or while it is in progress,
by the end-user.
Temperature regulation is active and has a NEUTRAL ZONE adjustment, the working setpoint is set by the end-user.
Relative humidity regulation is active and has a NEUTRAL ZONE adjustment, the working setpoint is set by the end-
user as is the evaporator fan speed.
Theoretically this phase has an infinite duration as it terminates when the cycle is interrupted by prolonged pressing
(for 4 seconds) of the
key.
To make it possible to regulate in these ways, the controller must manage the loads associated with cooling
(compressor, evaporator fan, defrost, pump-down solenoid valve), with heating (heating element), with humidification
(steam generator, steam injection valve) and with dehumidification (dehumidification by activating the refrigeration
plant). The way each function is regulated is described in subsequent sections.
