[0026] The cold water pipe 10 transports the external cold water to the heat exchanger 9, and the drain pipe 8 transports the condensed water with a higher temperature of the inner pot body 3 to the heat exchanger 9. The condensed water and the cold water exchange heat in the heat exchanger 9, thereby reducing the temperature of the condensed water. The cooled condensed water is transported to the water storage tank 12 for storage through the condensed water pipe 11. The water storage tank 12 is installed on the fixed frame 13 through the rotating shaft 14, and the rotating shaft 14 is driven to rotate by the motor 15, so that the water storage tank 12 rotates, thereby pouring the condensed water in the water storage tank 12, reducing the difficulty of pouring the condensed water and improving the safety during pouring. The sealing cover 1 is connected to the sterilizing pot body by the fastening bolts 4, which is convenient for opening and closing the sealing cover 1 and convenient for checking the sterilization medium.
