Abstract
Description
Technical Field
[0001] This utility model relates to the field of fermentation equipment technology, and in particular to a soybean fermentation device. Background Technology
[0002] Soybeans can be fermented to obtain soybean meal and soy isoflavones, and can also be used as feed ingredients. Fermentation is generally carried out in fermentation tanks, which typically consist of a tank body and a rotating shaft mounted inside the tank. A drive motor outside the tank rotates the shaft, which also has a stirring rod. Materials are introduced through a feed pipe on the tank body, and fermentation then begins. After fermentation, the materials are discharged through a discharge pipe at the bottom of the tank. In actual fermentation, the drive motor agitates the materials via the shaft and stirring rod, resulting in more uniform mixing. However, the materials are still subject to gravity and will fall during agitation, thus requiring higher stirring speeds and longer stirring times to achieve the desired mixing effect, which reduces mixing efficiency to some extent. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention provides a soybean fermentation device that solves the problem of reduced stirring efficiency caused by materials falling downwards due to gravity.
[0004] According to an embodiment of this utility model, a soybean fermentation device includes a tank. A partition plate is fixedly installed inside the tank, dividing it into an upper chamber and a lower chamber. An mounting sleeve is also fixedly installed at the center of the partition plate. An mounting shaft is coaxially installed inside the tank, rotatably passing through the mounting sleeve and extending to the top of the tank. A drive motor connected to the mounting shaft is also installed outside the tank. A first stirring rod and a second stirring rod, respectively located in the upper and lower chambers, are fixedly connected to the mounting shaft. A first spiral located in the lower chamber is also fixedly connected to the mounting shaft. Several through holes are also formed on the partition plate. When the fermentation device provided by this solution is running, the first spiral can lift the material upwards, thereby reducing the amount of material falling downwards, thus improving the stirring efficiency and solving the problem in the prior art where the stirring efficiency is reduced due to the material falling downwards due to gravity.
[0005] Furthermore, the diameter of the perforation is gradually increased, with the diameter being smaller near the mounting sleeve.
[0006] Furthermore, a second spiral with both ends penetrating the mounting sleeve is also fixedly connected to the mounting shaft.
[0007] Furthermore, a third spiral located in the upper chamber is also fixedly connected to the mounting shaft.
[0008] Furthermore, the third helix is also connected to the second helix.
[0009] Furthermore, the second stirring rod is fixed to the mounting shaft by the first connecting sleeve, and the first spiral is located below the first connecting sleeve.
[0010] Furthermore, the first stirring rod is fixed to the mounting shaft by the second connecting sleeve, and the second spiral is located below the second connecting sleeve.
[0011] Furthermore, a third stirring rod located below the first spiral is fixedly connected to the lower end of the mounting shaft.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] The material is moved upward by the first spiral, and a portion of the material is directed into the upper chamber by the mounting sleeve. The material in the upper chamber can also be directed downward through the perforations, thereby improving the mixing efficiency and solving the problem of reduced mixing efficiency caused by the material falling downward due to gravity in the prior art.

Detailed Implementation
[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0019] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0020] In an exemplary implementation, such as Figure 1-2 As shown, this embodiment provides a soybean fermentation device, which includes a tank 1. A partition plate 4 is fixedly installed inside the tank 1, dividing it into an upper chamber 2 and a lower chamber 3. An installation sleeve 5 is also fixedly installed at the center of the partition plate 4. An installation shaft 6 is coaxially installed inside the tank 1, rotatably passing through the installation sleeve 5 and extending to the top of the tank 1. A drive motor 7 connected to the installation shaft 6 is also installed outside the tank 1. A first stirring rod 8 and a second stirring rod 9, respectively located in the upper chamber 2 and the lower chamber 3, are fixedly connected to the installation shaft 6. A first spiral 10 located in the lower chamber 3 is also fixedly connected to the installation shaft 6. The partition plate 4 also has several through holes 11 for material to pass through. More specifically, the diameter of these perforations 11 is gradually changing, with the diameter being smaller near the mounting sleeve 5. When the drive motor 7 is running, the first spiral 10 lifts the material at the bottom upwards. Because the diameter of the perforations 11 near the mounting sleeve 5 is smaller, it is not easy for material to pass through. This allows more material to pass through the mounting sleeve 5 to the upper chamber 2. At the same time, the material in the upper chamber 2 can also enter the lower chamber 3 downwards through the outer perforations 11, while the inner perforations 11 can also allow a small amount of material to pass through. This prevents the material from falling and ensures the exchange of material between the upper chamber 2 and the lower chamber 3, ensuring efficient mixing and solving the problem of reduced mixing efficiency caused by the material falling downwards due to gravity in the prior art.
[0021] In a further embodiment, the mounting shaft 6 is also equipped with a second spiral 12 and a third spiral 13. The second spiral 12 is located inside the mounting sleeve 5, with both ends positioned above and below the mounting sleeve 5. This allows for more efficient upward lifting of the material below through the mounting sleeve 5 into the upper chamber 2. The third spiral 13 is located inside the upper chamber 2 and can be further connected to the upper end of the second spiral 12. After entering the upper chamber 2, the material is further lifted upward by the third spiral 13 and then spreads outward. This, combined with the first stirring rod 8 and the second stirring rod 9, makes the mixing of the material more efficient. In a more detailed embodiment, the second stirring rod 9 is fixed to the mounting shaft 6 via the first connecting sleeve 14, and the first spiral 10 is located below the first connecting sleeve 14. Similarly, the first stirring rod 8 is fixed to the mounting shaft 6 via the second connecting sleeve 15, and the second spiral 12 is located below the second connecting sleeve 15. This allows for closer coordination between the first stirring rod 8, the second stirring rod 9, the first spiral 10, and the third spiral 13, ultimately improving the mixing efficiency of the material.
[0022] In a further embodiment, the lower end of the mounting shaft 6 is also fixedly connected to a third stirring rod 16 located below the first spiral 10. The third stirring rod 16 is located at the bottom and can be arc-shaped. Below it is a discharge pipe 17, and the top of the tank body 1 is also provided with a feed pipe 18. In this way, the material is introduced from the feed pipe 18, stirred, and then discharged through the discharge pipe 17.
[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
