The sliders at the bottom of the sterilization basket are docked with the first track 25 and the second track 251 on the lower side inside the heating inner core cylinder 2, so that the sterilization basket enters the interior of the heating inner core cylinder 2. The front cover of the sterilizer 1 is closed, and by starting the switch of the heating coil 23, the heating coil 23 heats the interior of the sterilizer 1 to a temperature above 100°C. At the same time, the water body inside the sterilization basket is vaporized, so that a high-temperature and high-pressure environment is generated inside the sterilizer 1, achieving the purpose of heating the food inside the sterilization basket; the heating coil 23 is spirally arranged inside the heating inner core cylinder 2 and has a concentric circle structure with the heating inner core cylinder 2, which can ensure that the temperatures at all parts inside the heating inner core cylinder 2 are the same, and can uniformly heat the food inside the heating inner core cylinder 2; ensure that the food at all parts inside the pot can reach an effective sterilization temperature, kill microorganisms such as bacteria, fungi and spores, and improve the reliability and consistency of sterilization; at the same time, avoid the situation of local overheating or insufficient heating, and maximize the retention of the nutritional components, taste and color of the food; especially for canned aquatic products, it can prevent the problems of partial softening and partial hardness and ensure the overall quality; when the heating coil 23 is damaged and needs to be repaired, the three rows of fixing bolts 13 on the outside of the sterilizer 1 can be removed.
