How does water rotary type autoclave retor working?
water rotary autoclave / water rotary sterilizer or you can call it water rotary retort is a kin of autoclave used to the sterilization of food in different kind of packages, such as meat in glass jar, fish in tin can, beans in vacuum bag, sauce in pouch...
this kind of retort autoclave use steam as heating medium. this part of steam will heating water to a high temperature, usually 121 degree <sterilization temperatre>, this high temperature will be pumped from the retort bottom to the retort top and then fail to the retort bottom again.
this part of water will keep circulating until the sterilization time finished.
after steri;ization, cooling water will be pumped into the retort sterilizer to cooling the sterilized product temperature to a lower level.
after cooling, we finished the sterilization step.

WATERSPRAY SYSTEM WORKING PRINCIPLE
FEATURES
• Excellent temperature distribution
• Continuous process water

• Side spray for trays or pouches
• Continuous water level control and flow monitoring
• Programmable air-overpressure control
• Steam and water consumption minimal
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.
