Description of the sterilization pot
In the simplest terms, the sterilization pot is a sealed, pressurized heater used to heat the food sealed in the container. Seal packaging in the container to be commercially sterile sterile food, you can use a variety of different sterilization pot system. The sterilization pot system has some of the same characteristics:
The system is pressurized and the transfer temperature is much higher than boiling water.
The system uses a medium (called a heating medium or a sterilization medium) as a tool for transferring heat to the product. The media used in the pots include pure steam, hot water (all submerged containers in water, water spray or water spray) and steam / air mixtures.
Some systems use overpressure during sterilization and cooling to keep the integrity and balance of the container against the pressure in the tank. This is necessary because some packaging containers have limited endurance to internal pressure. Some examples of overpressure sterilization vessels are semi-rigid plastic containers with heat-sealed or bimetallic cans, soft bags, metal plates, cardboard containers and glass jars. The pressure at 250 ° F is about 15 psig (pounds per square inch) and any pressure above the 15 psig applied to the sterilization pot is referred to as overpressure. A sterilization system that provides overpressure, such as 25-35 psig, can operate at higher temperatures.
The operation of the sterilization pot must be appropriate to ensure that the container is sterile after sterilization.
