6. OPERATION
6.1 Preliminary notes
The controller supplies a complete control for retarder-proofer cabinets or cells for confectionery and bread-making,
through the automatic management of the complete mixture retarder-proofer cycle.
An automatic retarder-proffer cycle is composed of 5 different phases with different temperatures, relative humidity, fan
speed and duration, which are performed one after the other and precisely:
1. BLOCK phase
The block phase is the first phase of the automatic cycle.
Temperature regulation is active and is neutral area, the temperature set-point, the humidity set-point (the control if
envisioned), the speed of the fans and the duration in hours and minutes of the phase are established by the final user.
Adjustment of the relative humidity depends on parameter rU4. If set at zero, humidity control is not envisioned in this
phase.
2. STORAGE phase
The storage phase is the second phase of the automatic cycle.
Temperature regulation is active and is neutral area, the temperature set-point, the humidity set-point (the control if
envisioned), the speed of the fans and are established by the final user.
Adjustment of the relative humidity depends on parameter rU4. If set at zero, humidity control is not envisioned in this
phase.
The duration of this phase is calculated automatically by the controller on the basis of the duration of the lock, recovery,
proving phases and the day and time of proving end time desired for the mixture.
3. RECOVERY phase
The recovery phase is the third phase of the automatic cycle.
The temperature regulation is active and is NEUTRAL AREA, the work set-point is established by the final user. The
passage from the storage set-point (previous phase) to the recovery set-point can be gradual with increase percentages
established in the parameters programming phase.
The relative humidity regulation is active and is NEUTRAL AREA, the work set-point is established by the final user.
The duration in hours and minutes of the phase and the evaporator fan speed are established by the final user.
