[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given to illustrate in detail.

[0020] See Figure 1 The aerobic fermentation heating system of the present invention includes a first heating coil 7 with a first set of circulation ports 4 and a second heating coil 8 with a second set of circulation ports 6, mounted on a fermentation facility 9. The fermentation facility 9 can be an aerobic fermentation tank or an aerobic fermentation chamber. The first heating coil 7 and the second heating coil 8 are independent piping systems that do not interfere with each other. The first and second sets of circulation ports 4 and 6 facilitate piping connections to the heating device.

[0021] The system also includes temperature detection probes 5 for detecting the temperature inside the fermentation facility 9. As shown in the figure, two temperature detection probes 5 are provided, one located in the middle of the fermentation facility 9 and the other located at the bottom. The temperature values ​​measured by the two temperature detection probes 5 are averaged to obtain the temperature value inside the fermentation facility 9. This temperature value is used to determine whether to initiate heating. A controller 10 is also included for controlling the heating of the fermentation facility 9.

[0022] The system also includes a solar thermal device 1 installed on the workshop roof and an electric heating device 3 located within the workshop. Both devices are connected to fermentation facilities 9, providing heating for the facilities using solar thermal energy and electric heating, respectively. This constitutes a combined heating system. By utilizing solar thermal energy, electricity consumption is reduced, achieving environmental protection while also lowering the operational energy consumption of aerobic fermentation production activities.

[0023] See Figure 2, we can see that:

[0024] The solar thermal device 1 comprises a plurality of adjustable curved reflectors 1-6, with a heat absorption tube 1-5 mounted at the center of each curved reflector 1-6. Each heat absorption tube 1-5 is connected in series via a solar thermal connecting tube 1-8. The device also comprises a solar thermal supply tube 1-9, a solar thermal return tube 1-4, and a solar thermal circulation pump 1-3. These tubes are connected to a first set of circulation ports 4. Heat transfer oil circulates within the piping system, and the solar thermal circulation pump 1-3 provides power for this circulation.

[0025] In this embodiment, the solar thermal device 1 includes a rectangular support frame 1-2 supported by multiple legs 1-1. Multiple sets of supports are mounted on opposing sides of the support frame 1-2, and each heat absorbing tube 1-5 is secured to the support. The solar thermal device 1 is mounted and secured to the roof of the workshop via the multiple legs 1-1. The support frame 1-2 provides stable support for each set of heat absorbing tubes 1-5 and their curved reflector plates 1-6.

[0026] In this embodiment, fan-shaped mounting brackets 1-7 are installed at both ends of the arc-shaped reflective plate 1-6, and a sleeve is provided in the center of the mounting bracket 1-7. The heat absorption tube 1-5 passes horizontally through the sleeve of the mounting bracket 1-7 at both ends of the arc-shaped reflective plate 1-6 below it. A fastener is also provided on the sleeve, which can be a fastening screw. A radially penetrating threaded hole is provided on the side wall of the sleeve. The fastening screw is located in the threaded hole and the inner end of the fastening screw rests on the outer wall of the heat absorption tube 1-5.

[0027] In this way, the posture of the curved reflective plates 1-6 can be adjusted and set by operating the fasteners. After the solar thermal device 1 is installed and fixed on the roof of the workshop, the inclination angle of each curved reflective plate 1-6 can be adjusted and set according to the local sunshine conditions. The principle is: during periods of sufficient sunshine, such as noon, the concave surface of each curved reflective plate 1-6 should be facing the direction of the sun as much as possible, and with the change of seasons, the inclination angle of each curved reflective plate 1-6 should be adjusted appropriately on a regular basis to maximize the efficiency of obtaining solar thermal energy.

[0028] In this embodiment, the photothermal device 1 also includes an illuminance sensor 2, which is connected to the controller 10. The illuminance sensor 2 can detect the light intensity, so that the photothermal device 1 starts to operate under good lighting conditions and does not start to operate on rainy days, thereby avoiding ineffective operation.

[0029] See Figure 3 , we can see that:

[0030] The electric heating device 3 includes an electric heating tank, an electric heating supply pipe 3-7, an electric heating return pipe 3-8, and an electric heating circulation pump 3-6. The electric heating supply pipe 3-7 and the electric heating return pipe 3-8 are connected to the second set of circulation interfaces 6. The electric heating tank consists of a tank body and an electric heating component installed in the tank body, and uses water as the circulating medium.

[0031] In this embodiment, the electric heating tank of the electric heating device 3 includes a first electric heating tank 3-4 and a second electric heating tank 3-9. The outlet of the first electric heating tank 3-4 is connected to the inlet of the second electric heating tank 3-9 through the electric heating connecting pipe 3-2, so the first electric heating tank 3-4 and the second electric heating tank 3-9 are connected in series.

[0032] In this embodiment, a water supply pipe 3-3 is further installed on the tank wall of the first electric heating tank 3-4, and a water intake pipe 3-5 is further installed on the tank wall of the second electric heating tank 3-9. Water is replenished into the system through the water supply pipe 3-3, and hot water is taken from the system through the water intake pipe 3-5. The taken hot water can be used to meet the needs of the fermentation facility 9. Therefore, this combined heating system can also provide convenience in water supply for the fermentation facility 9.

[0033] In this embodiment, the electric heating device 3 also includes a rectangular protective frame 3-1, and the first electric heating tank 3-4, the second electric heating tank 3-9, the electric heating circulation pump 3-6 and the auxiliary pipelines are installed inside the protective frame 3-1 to provide certain protection functions.

[0034] The controller 10 is constructed based on PLC, and the temperature detection probe 5, the photothermal circulation pump 1-3, the electric heating circulation pump 3-6, the heating components of the first electric heating tank 3-4 and the second electric heating tank 3-9, and the illumination sensor 2 are all connected to the controller 10. The controller 10 compares the temperature conditions in the fermentation facility 9 obtained by the temperature detection probe 5 with the set fermentation temperature, and combines the outdoor illumination conditions detected by the illumination sensor 2 to determine whether to enable the photothermal device 1 or the electric heating device 3 or both devices to run simultaneously.
