■DTS canned vegetable sterilization retort uses the continuous rotation of its rotating body to effectively promote the all-round 360-degree flow of vegetables inside the packaging, ensuring that the sterilization process is fully covered and even without dead ends. During the sterilization operation, steam is injected into the sterilization retort and displaces all cold air at the same time, thereby creating an efficient sterilization environment without cold air interference. This is a key step to optimize the sterilization effect.
