[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0019] As Figure 1 shown, a bioreactor for the production of biochemistry products includes a reaction tank 1. A protective shell 2 is provided outside the reaction tank 1. A heating chamber is provided between the protective shell 2 and the reaction tank 1. A water inlet pipe 3 is provided at the lower part of one side of the heating chamber, and a water outlet pipe 4 is provided at the upper part of the other side. A maintenance opening 15 is provided at the top of the reaction tank 1, and a cover plate is installed at the maintenance opening 15. A plurality of support legs 16 are provided at the bottom of the protective shell 2.

[0020] Connecting the heating chamber to a hot water circulation system through the water inlet pipe 3 and the water outlet pipe 4 enables the hot water circulation to heat the reaction tank 1.

[0021] As Figure 1 and Figure 2 shown, a feed pipe 5 is provided at the upper part of the side of the reaction tank 1, and a discharge pipe 6 penetrating through the protective shell 2 is provided at the bottom. An air inlet pipe 17 penetrating through the side wall of the protective shell 2 is connected between the side of the discharge pipe 6 and the reaction tank 1 and the protective shell 2. An air outlet pipe 18 is provided at the top of the reaction tank 1 on one side of a motor 7. A solenoid valve is installed on the discharge pipe 6, and a check valve is installed on the air inlet pipe 17.

[0022] In the state of closing the solenoid valve, sterile air or other production gases are input into the reaction tank 1 through the air inlet pipe 17.

[0023] As Figure 2 and Figure 3 shown, a stirring assembly is installed inside the reaction tank 1, and a motor 7 for driving the stirring assembly to rotate is installed at the top; the stirring assembly includes a stirring shaft 8 connected to the output shaft of the motor 7. A stirring blade 9 is installed at the lower part of the stirring shaft 8, and a plurality of connecting rods one 10 are fixedly connected to the upper part. A scraping plate one 11 is installed on the connecting rods one 10. The bottom end of the stirring shaft 8 extends into the discharge pipe 6, and a spiral blade 12 adapted to the discharge pipe 6 is fixedly connected to the bottom of the stirring shaft 8. A plurality of connecting rods two 13 are fixedly connected above the spiral blade 12 at the bottom of the stirring shaft 8, and a scraping plate two 14 is installed on the connecting rods two 13.

[0024] During the production process, the motor 7 drives the stirring shaft 8 to rotate forward. The stirring shaft 8 drives the stirring blades 9, the first scraper 11, the second scraper 14 and the spiral blade 12 to rotate. The first scraper 11 and the second scraper 14 can turn the materials at the inner wall of the reaction tank 1, enabling them to be mixed with the materials at the center of the reaction tank 1. Thus, the overall heating of the materials can be quickly made uniform, avoiding overheating of the materials at the inner wall of the reaction tank 1. The forward rotation of the spiral blade 12 can convey the discharge pipe 6 upward, preventing materials from accumulating in the discharge pipe 6. When discharging is required after production is completed, the solenoid valve is opened, and the motor 7 drives the stirring shaft 8 and the spiral blade 12 to rotate in the reverse direction. The materials can be evenly discharged through the spiral blade 12, effectively preventing the discharge pipe 6 from being blocked.

[0025] In specific use, the heating cavity is connected to the hot water circulation system through the water inlet pipe 3 and the water outlet pipe 4. Solid and liquid materials are added into the reaction tank 1 through the feed pipe 5. The motor 7 drives the stirring shaft 8 to rotate forward. The first scraper 11 and the second scraper 14 can turn the materials at the inner wall of the reaction tank 1, enabling them to be mixed with the materials at the center of the reaction tank 1. Thus, the overall heating of the materials can be quickly made uniform, avoiding the materials at the inner wall of the reaction tank 1 from having too high a temperature. When discharging, the motor 7 drives the stirring shaft 8 and the spiral blade 12 to rotate in the reverse direction. The materials can be evenly discharged through the spiral blade 12, effectively preventing the discharge pipe 6 from being blocked.
