Food retort sterilization is a pressure vessel that uses saturated steam or high-temperature hot water to heat treat canned food. In industrial production, putting canned food that needs to be sterilized into a sterilization pot and applying a continuous and uniform high temperature for a certain period of time can eliminate microorganisms in food, destroy biological enzymes, and have a bactericidal effect on the activity of heat-resistant spores, achieving commercial sterility and greatly extending the shelf life of canned food, so that it can be stored at room temperature for a certain period of time without spoilage. After sterilization, compressed air must be used to apply external pressure (commonly known as back pressure) to the cans during the cooling process to protect them from being damaged by excessive internal pressure. The autoclave equipment plays a vital role in the food sterilization industry, ensuring the safety of food and extending the shelf life of all kinds of food.
