Steam And Rotary Retort
Steam and rotary retort is to use the rotation of the rotating body to make the contents flow in the package. It is inherent in the process that all air be evacuated from the retort by flooding the vessel with steam and allowing the air to escape through vent valves.There is no overpressure during the sterilization phases of this process, since air is not permitted to enter the vessel at any time during any sterilization step. However, there may be air-overpressure applied during the cooling steps to prevent container deformation. -
Direct Steam Retort
The Saturated Steam Retort is the oldest method of in-container sterilization used by human. For tin can sterilization, it’s the simplest and most reliable type of retort.

Automated Batch Retort System
The trend in food processing is to move away from small retort vessels to larger shells to improve efficiency and product safety. Larger vessels imply larger baskets that can’t be handled manually. Large baskets are simply too bulky and too heavy for one person to move around.
