Multiple sets of first heating plates heat the water in the sterilizer to sterilize the materials. Simultaneously, the second water inlet valve is opened to drain water into the steam generation chamber, where multiple sets of second heating plates heat the water. An exhaust pump is activated to pressurize the steam in the steam generation chamber and discharge it into the sterilizer, increasing the pressure inside the sterilizer and creating steam pressure, thereby improving the sterilization effect of the equipment on the materials.

[0028] A secondary pot device 2 is placed on one side of the main pot device 1, and the structure of the secondary pot device 2 is the same as that of the main pot device 1.

[0029] The two ends of the high-temperature water pump 3 are connected to the high-temperature pipe 108 on the main pot tank device 1 and the high-temperature pipe 108 on the auxiliary pot tank device 2 through flanges. The top flange of the high-temperature pipe 108 on the main pot tank device 1 away from the main pot tank device 1 is connected to a manual drain valve 302, which is used to drain the water in the tank. The top flange of the high-temperature pipe 108 on the auxiliary pot tank device 2 away from the auxiliary pot tank device 2 is connected to a water supply pump 301. A power supply 303 is placed inside the main pot tank device 1 and the auxiliary pot tank device 2. The power supply 303 is connected to a heating element 304 through a wire. The number of heating elements 304 is set to two sets, and the two sets of heating elements 304 are placed on the inner circumferential bottom side of the main pot tank device 1 and the auxiliary pot tank device 2 respectively.

[0030] The steam circulation device 4 includes a support plate 401, a first electric steam valve 402, a second electric steam valve 403, and a steam pipe 404. The two ends of the support plate 401 are fixedly installed at the center of the outer peripheral wall of the outer tank 101 on the main boiler 1 and the auxiliary boiler 2. The first electric steam valve 402 and the second electric steam valve 403 are fixedly installed on the upper surface of the support plate 401. L-shaped pipes are connected to the flanges on both sides of the first electric steam valve 402 and the second electric steam valve 403. A steam pipe 404 is connected to one side of the first electric steam valve 402 and the second electric steam valve 403 via an L-shaped pipe. The steam pipe 404 is located inside the inner tank 111 on the main boiler 1 and the auxiliary boiler 2. The L-shaped pipe on the first electric steam valve 402 connects to the steam pipe 404 inside the main boiler 1. The L-shaped pipe at the other end of valve 402 is connected to the interior of the inner tank 111 on the auxiliary boiler device 2. The L-shaped pipe connection of the second electric steam valve 403 is opposite to that of the first electric steam valve 402. The L-shaped pipe on the second electric steam valve 403 is connected to the steam pipe 404 inside the auxiliary boiler device 2. The L-shaped pipe at the other end of the second electric steam valve 403 is connected to the interior of the inner tank 111 on the main boiler device 1. There are four sets of steam pipes 404, which are arranged vertically and horizontally. Multiple sets of steam nozzles 405 are provided along the axial direction of the steam pipes 404. A circular pipe 406 is connected to the middle of the steam pipes 404. The circular pipes 406 are connected in series to each set of steam pipes 404. A support frame 407 is installed on the outer circumference of the steam pipes 404. The end of the support frame 407 away from the steam pipes 404 is fixedly installed on the inner circumferential wall of the inner tank 111.

[0031] The working principle of the specific implementation method is as follows: The main boiler tank 1 and the auxiliary boiler tank 2 operate independently. Material is pushed into the inner tank 111 of the auxiliary boiler tank 2. The control panel 104 starts the water pump 301 to inject process water into the auxiliary boiler tank 2. The air valve 109 discharges air from the tank. When the water level exceeds the material height, the water pump 301 stops supplying water. The heating element 304 inside the auxiliary boiler tank 2 starts, heating the water inside. The high temperature sterilizes the material. Continuous heating generates steam. Excessive steam can affect the closed tank. When high pressure is generated, exceeding the pressure value set by safety valve 107, safety valve 107 automatically discharges. Simultaneously, with the high-temperature water pump 3 and the first electric steam valve 402 and second electric steam valve 403 closed, the main boiler unit 1 and auxiliary boiler unit 2 are not interconnected. While auxiliary boiler unit 2 is heating and sterilizing, the main boiler unit 1 is being filled with materials. After filling, the electronic boiler lid lock 105 closes. The main control panel 104 checks that the electronic boiler lid lock 105 is fully closed, and then the first electric steam valve 402 is activated, allowing steam from the auxiliary boiler unit 2 to pass through the first... Electric steam valve 402 connects to the L-shaped pipe of auxiliary boiler tank 2. Steam flows through the first electric steam valve 402, and then from the first electric steam valve 402 to the L-shaped pipe of the main boiler tank 1, delivering steam to the interior of steam pipe 404 and circular pipe 406. Steam is ejected from steam nozzle 405 to preheat the material inside the main boiler tank 1. To ensure that the steam discharged from the auxiliary boiler tank 2 does not reduce the pressure and temperature inside the auxiliary boiler tank 2, a safety valve 107 is installed to release pressure values ​​greater than those of the first electric steam valve 402 and the second electric steam valve. When valve 403, the first electric steam valve 402, and the second electric steam valve 403 are activated, and steam is exchanged between the main boiler tank 1 and the auxiliary boiler tank 2, if the pressure value inside the tank does not exceed the release pressure value set by safety valve 107, then safety valve 107 stops releasing. If the release pressure values ​​of the first electric steam valve 402 and the second electric steam valve 403 are greater than the pressure values ​​required for sterilization of the materials in the main boiler tank 1 and the auxiliary boiler tank 2, the steam generated by the auxiliary boiler tank 2 during heating and sterilization preheats the materials in the main boiler tank 1, shortening the sterilization time.

[0032] After the sterilization operation of the auxiliary boiler tank 2 is completed, the high-temperature water pump 3 is started to extract the high-temperature water from the auxiliary boiler tank 2. During the extraction process, the pressure inside the tank decreases, and air is introduced into the air valve 109. The high-temperature water in the auxiliary boiler tank 2 flows into the main boiler tank 1 through the high-temperature water pump 3. The heating element 304 heats and maintains the temperature of the high-temperature water to sterilize the main boiler tank 1. The air valve 109 introduces air to cool down the auxiliary boiler tank 2. Water can also be added to the main boiler tank 1 and the auxiliary boiler tank 2 to cool them down. After cooling, the next batch of materials is replaced. The steam generated by the process water in the heating tank of the main boiler tank 1 preheats the second batch of materials in the auxiliary boiler tank 2 through the second electric steam valve 403, saving sterilization time for the materials. The main boiler (tank 1) and auxiliary boiler (tank 2) are used alternately to sterilize materials. During the next sterilization cycle, the high-temperature water requires a shorter time to maintain its high temperature using the heating element 304, thus reducing energy consumption and solving the problem of long heating times and excessive energy consumption associated with repeatedly heating process water from ambient temperature to high temperature in a single boiler. The high-temperature water in both main boiler (tank 1) and auxiliary boiler (tank 2) serves a storage function while the two boilers are used alternately for sterilization, avoiding water waste. The use of main boiler (tank 1) and auxiliary boiler (tank 2) solves the problem of low efficiency in sterilization operations using a single boiler.
