Description

Technical Field

[0001] This utility model relates to the field of fermentation tank technology, specifically a microbial anaerobic fermentation tank for baijiu brewing. Background Technology

[0002] A fermentation tank is an industrial device used for microbial fermentation. Its main body is generally a cylindrical column made of stainless steel. In its design and manufacturing, attention should be paid to a tight and reasonable structure. In the process of brewing baijiu (Chinese liquor), yeast ferments starchy and sugary raw materials to produce alcohol and form liquor.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN221917959U) discloses an anaerobic fermentation tank for baijiu (Chinese liquor) brewing. The tank includes an inert gas inlet pipe, an exhaust pipe, and a tank body with a sealed cap. The top of the tank body has a feed inlet with a valve, and the bottom of the tank body has a liquid outlet with a valve. A heating coil is fitted inside the tank body, with one end connected to a steam inlet located outside the tank body and the other end connected to a steam condensate outlet located outside the tank body. A temperature control jacket is fitted outside the tank body, with a hot and cold water pipe inlet and outlet connected to its internal cavity. The tank body is equipped with an internal environment monitoring device, which includes a temperature detector, a pressure sensor, a pH detection component, and a dissolved oxygen detection component. This utility model can provide more suitable anaerobic growth conditions, facilitating industrial-scale production.

[0004] Although the aforementioned patent achieves heating treatment during the fermentation of baijiu, it still uses a traditional stirring paddle for mixing. When the stirring paddle in the traditional fermentation tank is used for mixing, most of the baijiu fermentation substances will settle at the bottom of the fermentation tank due to their gravity. This results in uneven distribution of microorganisms in the fermentation mash, forming local enrichment areas and barren areas. This leads to over-fermentation in some areas and under-fermentation in others, thus affecting the uniformity of fermentation.

[0005] Therefore, this utility model provides a microbial anaerobic fermentation tank for brewing baijiu (Chinese liquor) to solve the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-6 As shown, this utility model provides a microbial anaerobic fermentation tank for baijiu brewing, including a tank body 1, a tank cover 14 fixedly connected to the top of the tank body 1, a first motor 16 fixedly connected to the top of the tank cover 14, an output end of the first motor 16 extending through to the bottom of the tank cover 14 and fixedly connected to a stirring shaft 17, an irregularly shaped stirring paddle 18 and an auger propeller 19 fixedly connected to the outer wall of the stirring shaft 17; a filter pipe 2, fixedly connected to the inner wall of the tank body 1, and a feeding pipe 21 integrally formed on the inner wall of the filter pipe 2, with the auger propeller 19 rotatably disposed inside the feeding pipe 21; and an evacuation assembly 4. The evacuation assembly 4 is fixedly connected to the top of the feeding pipe 21. With this structure, the stirring shaft 17 is driven to rotate by the first motor 16, which in turn drives the shaped stirring paddle 18 and the auger propeller 19 to rotate. Furthermore, through the filter pipe 2 and the feeding pipe 21, the material precipitated inside the filter pipe 2 can be guided to the inside of the feeding pipe 21. Then, under the rotation of the auger propeller 19, it is transported upward, thus transporting the precipitated material to the middle of the tank 1. With the rotation of the shaped stirring paddle 18, it can achieve full mixing, thereby improving the uniformity of fermentation.

[0028] Furthermore, the outer wall of the tank 1 is integrally formed with a liquid outlet 11, and the liquid outlet 11 is filtered by the filter pipe 2 to ensure the cleanliness of the discharged liquid and reduce the impurity of solid substances. The outer wall of the tank 1 is evenly distributed with positioning lugs 13. The bottom of the tank 1 is integrally formed with a solid outlet 12, and the bottom flange of the solid outlet 12 is fixedly connected to a discharge pipe 3. The outer wall of the discharge pipe 3 is fixedly connected with a second motor 31. The output end of the second motor 31 passes through the inside of the discharge pipe 3 and is fixedly connected with a plate valve 32. The outer diameter of the plate valve 32 is equal to the inner diameter of the discharge pipe 3. By driving the plate valve 32 to rotate, the discharge pipe 3 can be opened and closed. Thus, when the plate valve 32 is sealed, fermentation can be carried out inside the tank 1. Conversely, the solid substances inside the tank 1 can be discharged. At the same time, with the cooperation of the auger propeller 19, the solid substances inside the filter pipe 2 are conveyed downward by the reverse rotation of the auger propeller 19, improving the smoothness and convenience of the discharge.

[0029] Furthermore, a manhole 15 is provided on the top of the tank cover 14, and the tank cover 14 is fixedly connected to the tank body 1 by a flange. The irregularly shaped stirring paddle 18 is located above the auger propeller 19, and the irregularly shaped stirring paddle 18 and the auger propeller 19 are distributed at the same height.

[0030] Furthermore, four discharge ports 22 are evenly distributed around the bottom circumference of the feeding pipe 21, and filter holes are evenly distributed around the circumference of the filter pipe 2 and the feeding pipe 21. The top diameter of the filter pipe 2 is equal to the inner diameter of the tank body 1, and the bottom diameter of the filter pipe 2 is equal to the inner diameter of the solid outlet 12. The filter pipe 2 can play an auxiliary filtration role, preventing solid substances from being discharged through the liquid outlet 11. At the same time, it can guide the solid substances to settle and flow into the inside of the feeding pipe 21, so that the screw conveyor propeller 19 can work to rise and stir the substances inside the feeding pipe 21.

[0031] Furthermore, the evacuation assembly 4 includes a positioning ring 41, which is flanged and fixedly connected to the top of the feed pipe 21. A support shaft 42 is fixedly connected to the outer wall of the positioning ring 41, and an evacuation net 43 is fixedly connected to the inner wall of the positioning ring 41. A collar 44 is fixedly connected to the inner wall of the evacuation net 43, and the collar 44 is fitted onto the outer wall of the stirring shaft 17. Through this structure, it covers the top of the feed pipe 21. When the auger propeller 19 works and drives the material to rise, the material that has condensed into lumps can be squeezed and dispersed through the division of the evacuation net 43, thereby reducing the occurrence of material agglomeration and further improving the uniformity of mixing.

[0032] Working principle: First, an appropriate amount of fermentation material is added to the inside of the tank 1. Then, the first motor 16 is driven. The operation of the first motor 16 drives the stirring shaft 17 to rotate, which in turn drives the irregularly shaped stirring paddle 18 and the auger propeller 19 to rotate. While the auger propeller 19 is rotating, it can transport the material that has settled inside the filter tube 2 upward through the feeding pipe 21. When the material is transported to the top of the feeding pipe 21, it is squeezed and contacted with the dispersing net 43 to achieve the dispersing treatment of the material and avoid the formation of clumps. At the same time, with the rotation of the irregularly shaped stirring paddle 18, the material transported to the top of the feeding pipe 21 can be agitated and mixed a second time, thereby improving the uniformity of the fermentation material mixture.

[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
