retort machine Working Principle:
1. Water filing
Prior to the start of the process, the retort is filled with a small volume of process water 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 sterilizec with each cycle.
Once the cycle is begins, the steam valve opens and the circulation pump is switched on. The mixture of steam and water spraying from top of the retort vessel creats highly turbulent convection currents that rapidly homogenizes the temperature at every point in the retort and between the containers.
Once the programmed sterilization temperature has been reched, it is held for the programmed time with +/-1 °F . Similarly, the pressure is kept with +/- 1 psi by adding and venting compresed air as needed.
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 on side of a plate heat exchanger. At the same time, cold water passes through the other side of 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 closed and the pressure inside thr retort is autoamtically relieved. The water level is lowered from the maximun down to the medium level. The door is equipped with a safety locking device which prevents the oping of the door in the case of residual pressure or high water level.
