Problems solved by technology

However, the fresh-keeping pot with this structure not only has a complicated structure and high production cost, but also the exhaust gas of combustion cannot be discharged, causing pollution to food, and it cannot be boiled again after the spores germinate and grow under the condition of isolating the outside air to achieve Atmospheric pressure intermittently boiled and sterilized for a long time to achieve long-term freshness preservation. It can only be kept fresh at room temperature for a short period of time, and cannot meet the actual needs of long-term preservation of marinade and old soup.
