The output end of the drive motor extends into the inside of the sealing cover and is fixedly connected to the first connecting sleeve.

[0009] As a further technical solution of this utility model, stirring blades are connected to the outer sides of the first rotating rod and the second rotating rod at equal intervals and in parallel with each other along their side walls. A scraper is also installed at the end of the first rotating rod, and the scraper slides and fits against the inner bottom surface of the tank.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, a laboratory fermenter with an auxiliary mixing mechanism includes a tank body 1. A sealing cover 2 is provided on the top of the tank body 1, and support columns 6 are installed at equal intervals around the bottom of the tank body 1 via a jacket 7. A feed pipe 4 is connected through the top of the sealing cover 2, and a discharge pipe 5 is connected to the bottom of the tank body 1. A first fixing ring 8 is connected to the bottom of the outer side wall of the sealing cover 2, and a second fixing ring 9 is connected to the top of the outer side wall of the tank body 1. The first fixing ring 8 and the second fixing ring 9 are connected by a screw. An observation window 10 is connected to one side of the outer side wall of the tank body 1. First, the first fixing ring 8 and the second fixing ring 9 are connected to each other by a screw, so that the sealing cover 2 and the tank body 1 are closely fitted and sealed. Then, high-temperature steam is transported to the jacket 7 through a pipeline to preheat the fermentation liquid before sterilization. At the same time, the valve on the feed pipe 4 is opened to add the materials and microorganisms into the tank body 1 in sequence, and then the mixture is stirred and fermented. During the fermentation process, it can be observed through the transparent observation window 10. When the fermentation is completed, the valve on the discharge pipe 5 is opened to discharge the fermentation products along the discharge pipe 5.

[0021] The sealing cover 2 is internally equipped with a mixing mechanism for stirring and mixing the materials inside the tank 1. The mixing mechanism includes a triangular bracket 11 fixedly mounted on the inner wall of the sealing cover 2. A first connecting sleeve 14 is rotatably connected to the center of the triangular bracket 11. A first gear 12 is mounted on the outer surface of one end of the first connecting sleeve 14, and a first rotating rod 16 is connected to the lower surface of the other end through a first threaded sleeve hole 20. Second connecting sleeves 15 are rotatably connected to the center of the three sides of the triangular bracket 11. One end of each of the three sets of second connecting sleeves 15 is rotatably connected to the inner bottom surface of the sealing cover 2, and the outer surface... A second gear 13 is installed on the surface. A second rotating rod 17 is connected to the lower surface of the other end of the second connecting sleeve 15 through a second threaded sleeve hole 21. The first gear 12 and the second gear 13 are meshed. A drive motor 3 is installed on the outer top of the sealing cover 2. The output end of the drive motor 3 extends into the interior of the sealing cover 2 and is fixedly connected to the first connecting sleeve 14. Stirring blades 18 are connected to the outer sides of the first rotating rod 16 and the second rotating rod 17 at equal intervals and parallel to each other along their side walls. A scraper 19 is also installed at the end of the first rotating rod 16, and the scraper 19 slides against the inner bottom surface of the tank body 1. During use, the staff uses first rotating rods 16 and second rotating rods 17 of different specifications and shapes according to the different types of fermentation materials inside the tank 1. These rods are fixedly connected to first connecting sleeves 14 and second connecting sleeves 15 through first threaded sleeve holes 20 and second threaded sleeve holes 21. Then, the drive motor 3 is started to drive the first connecting sleeve 14 on the triangular bracket 11 to rotate. This causes the first gear 12 to drive the second gear 13 to rotate on the triangular bracket 11 under the meshing characteristics. As a result, the stirring blades 18 on the first rotating rod 16 and second rotating rod 17 simultaneously mix and stir the materials and microorganisms in different positions inside the tank 1, preventing uneven mixing and improving the efficiency of fermentation production. At the same time, the scraper 19 facilitates the stirring of fermentation materials that have settled on the bottom surface of the tank 1, making them flow and ferment thoroughly, and preventing solidification that would affect the fermentation effect.

[0022] The working principle of this utility model is as follows: Before use, the staff uses the first rotating rod 16 and the second rotating rod 17 of different specifications and shapes according to the fermentation material. Then, they fix them to the first connecting sleeve 14 and the second connecting sleeve 15 through the first threaded sleeve hole 20 and the second threaded sleeve hole 21. After the replacement is completed, the sealing cover 2 is placed on the top of the tank body 1 for alignment and is fixed to each other by screws. Then, high temperature steam is transported to the jacket 7 through the pipeline to preheat the fermentation liquid before sterilization. Then, the fermentation material and microorganisms are transported to the inside of the tank body 1 along the feed pipe 4.

[0023] After the fermentation materials and microorganisms are added, the drive motor 3 is started, which drives the first gear 12 on the first connecting sleeve 14 to drive the second gear 13 on the second connecting sleeve 15 to rotate. This allows the stirring blades 18 on the first rotating rod 16 and the second rotating rod 17 to simultaneously mix and stir the materials and microorganisms at different positions inside the tank 1, preventing uneven mixing and improving the efficiency of fermentation production. At the same time, the scraper 19 facilitates the stirring of the fermentation materials that have settled on the bottom surface of the tank 1, preventing solidification and affecting the fermentation effect.

[0024] During fermentation, the fermentation process can be observed through the transparent observation window 10. Once fermentation is complete, the fermentation products can be discharged along the discharge pipe 5 by opening the valve on the discharge pipe 5.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
