WATERSPRAY SYSTEM WORKING PRINCIPLE
1. WATER FILLING
Prior to the start of the process, the retort is filled with a small volume of
process water (approx. 27 gallons/basket) such that the water level is below
the bottom of the baskets. This water can be used for successive cycles if
desired, as it is sterilized with each cycle.
2. HEATING
Once the cycle is begins, the steam valve opens and the circulation pump is
switched on. The mixture of steam and water spraying from the top and the
sides of the retort vessel creates highly turbulent convection currents that
rapidly homogenizes the temperature at every point in the retort and
between the containers.
3. STERILIZATION
Once the programmed sterilization temperature has been reached, it is held
for the programmed time within +/- 1º F. Similarly, the pressure is kept
within +/-1 psi by adding and venting compressed air as needed.
4. COOLING
At the end of the sterilization step, the retort switches into cooling mode. As
the process water continues to be circulated through the system, a portion of
it is diverted through one side of a plate heat exchanger. At the same time,
cold water passes through the other side of the plate heat exchanger. This
results in the process water inside the retort chamber being cooled in a
controlled fashion.
5. END OF CYCLE
Once the retort is cooled to the programmed temperature setpoint, the cold
water inlet valve on the heat exchanger closes and the pressure inside the
retort is automatically relieved. The water level is lowered from the
maximum down to the medium level. The door is equipped with a safety
locking device which prevents the opening of the door in the case of residual
pressure or high water level.
