[0018] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] like Figs. 1-3 As shown, a sterile fermenter based on heat exchange technology includes a tank body 1. A heat exchange jacket 2 is provided at the bottom of the tank body 1. A heat exchange cavity 3 exists between the inner wall of the heat exchange jacket 2 and the outer wall of the tank body 1. A water inlet pipe 21 is provided at the top of the heat exchange jacket 2, and a water outlet pipe 22 is provided at the bottom. The water inlet pipe 21 is used to deliver a first heat exchange medium to the inside of the heat exchange cavity 3, and the water outlet pipe 22 is used to discharge the first heat exchange medium to the outside of the heat exchange cavity 3. A spiral tube 23 is provided on the inner wall of the heat exchange jacket 2. Both ends of the spiral tube 23 extend to the outside of the heat exchange jacket 2. A second heat exchange medium is provided inside the spiral tube 23. The properties of the first heat exchange medium are opposite to those of the second heat exchange medium.

[0020] During fermentation, a first heat exchange medium can be supplied to the heat exchange cavity 3 through the water inlet pipe 21. This first heat exchange medium is a high-temperature hot medium, thus providing heat to the tank 1 for material fermentation. During fermentation, the material itself generates heat, resulting in a relatively high overall heat level in the heat exchange jacket 2 and tank 1. At this point, a second heat exchange medium, a lower-temperature cold medium, can be supplied to the spiral tube 23. The flow of the second heat exchange medium within the spiral tube 23 reliably absorbs and dissipates the heat from the first heat exchange medium, thereby reliably controlling the temperature of the first heat exchange medium and ensuring reliable fermentation. Furthermore, after absorbing heat, the second heat exchange medium warms up to the temperature of the first heat exchange medium, allowing it to be supplied to other fermenters or used for other purposes.

[0021] The inlet end of the spiral tube 23 is located below the end of the water inlet pipe 21, and the outlet end of the spiral tube 23 is located above the end of the water inlet pipe 21. The first heat exchange medium is transported from top to bottom into the heat exchange cavity 3, while the second heat exchange medium flows from bottom to top within the spiral tube 23. In this way, the first and second heat exchange media can be in a state of relative flow, thereby improving the heat exchange efficiency of the second heat exchange medium on the first heat exchange medium.

[0022] The bottom of the heat exchange jacket 2 is provided with several support legs 24, which are used to support the heat exchange jacket 2 and the tank 1, so that the tank 1 can be in a reliable working state. Furthermore, a material inlet is provided at the top of the tank 1, through which materials can be conveyed into the tank 1 or the fermented materials can be taken out from the tank 1.

[0023] The front end of the water outlet pipe 22 is provided with an electromagnetic valve 221, which is used to control the opening and closing of the water outlet pipe 22. When the heat exchange cavity 3 is filled with the first heat exchange medium, the water outlet pipe 22 can deliver gas into the heat exchange cavity 3, which is used to heat or disturb the first heat exchange medium. When the electromagnetic valve 221 is opened and water vapor is delivered into the heat exchange cavity 3 through the water outlet pipe 22, the first heat exchange medium in the heat exchange cavity 3 can be heated, thereby ensuring that the first heat exchange medium can deliver sufficient heat to the tank 1 for the fermentation of the material. Further, when the electromagnetic valve 221 is opened and air is delivered into the heat exchange cavity 3 through the water outlet pipe 22, the air is injected into the heat exchange cavity 3, which can form a disturbing effect on the first heat exchange medium in the heat exchange cavity 3, ensuring that the heat can be uniformly distributed in the first heat exchange medium, thereby improving the accuracy of heat exchange.

[0024] The front end of the water outlet pipe 22 and the electromagnetic valve 221 are located outside the heat exchange jacket 2, and the end of the water outlet pipe 22 is located inside the heat exchange jacket 2. The end of the water outlet pipe 22 is closed, and a plurality of branch pipes 222 are provided on the outer wall of the end of the water outlet pipe 22. One end of the branch pipe 222 communicates with the water outlet pipe 22, and the other end communicates with the heat exchange cavity 3. Since the end of the water outlet pipe 22 is closed, the gas in the water outlet pipe 22 will be completely discharged from the branch pipe 222. Thus, the plurality of branch pipes 222 can inject gas into the heat exchange cavity 3 from different directions, significantly improving the heating or disturbing effect on the first heat exchange medium. The end of the branch pipe 222 is connected to the water outlet pipe 22 through a corrugated pipe 223, and the plurality of branch pipes 222 extend in the radial direction of the water outlet pipe 22. The corrugated pipe 223 can produce a certain amount of deflection, so that the angle between the branch pipe 222 and the water outlet pipe 22 can be adaptively changed, further improving the heating or disturbing effect on the first heat exchange medium.

[0025] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and substitutions made by those skilled in the art based on the present application are within the scope of the present application.
