Description

Technical Field

[0001] This utility model relates to the technical field of soy milk fermentation equipment, specifically to a soy milk fermentation equipment. Background Technology

[0002] Fermented soy milk is a dairy product made primarily from soybeans through a specific lactic acid bacteria fermentation process. It not only converts soybean protein into amino acids that are more easily absorbed by the human body, but is also rich in nutrients such as probiotics, calcium, and vitamin B12, which help regulate intestinal flora and promote digestion. The fermentation tank is a key piece of equipment in its production process. It utilizes microorganisms under suitable temperature, pH, and dissolved oxygen conditions to convert substrates such as lactose in soy milk into beneficial components such as lactic acid. During fermentation, the stirring system continuously stirs the soy milk to ensure full contact between it and the microorganisms, thus ensuring the smooth progress of the fermentation process.

[0003] However, fermented soy milk has a certain viscosity and tends to adhere to the inner wall of the fermentation tank, making it difficult to clean. Most existing methods for cleaning the inner wall of fermentation tanks involve installing scrapers on both sides of the stirring blades and connecting them to the stirring shaft via a connecting plate. The scrapers move along the inner wall of the fermentation tank as the shaft rotates, scraping away the soy milk adhering to the walls. However, after prolonged use, the scrapers wear down due to friction against the inner wall, creating gaps that are difficult to clean, thus reducing the cleaning effectiveness of the fermentation tank's inner wall. Therefore, those skilled in the art have provided a soy milk fermentation device to solve the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to provide a fermented soybean milk device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fermented soybean milk device includes: a tank body and a tank lid. A motor is installed at the middle position of the top of the tank lid. A mixing mechanism is installed in the inner cavity of the tank body. The mixing mechanism includes a stirring shaft. One end of the stirring shaft extends out of the tank body and passes through the tank lid and is installed at the output end of the motor. The outer wall of the stirring shaft located in the inner cavity of the tank body is provided with a plurality of first stirring blades and second stirring blades for stirring materials. A horizontal plate is provided on the outer wall of the stirring shaft above the second stirring blades. Both ends of the horizontal plate have slots. An extension plate is slidably installed in the slots. The extension plate passes through the horizontal plate and extends to its outside. A scraper is provided at the end of the extension plate outside the horizontal plate. The scraper is attached to the inner wall of the tank body. A limit seat is provided in the slot on one side of the extension plate. A limit bolt is provided on the upper part of the horizontal plate at a position corresponding to the limit seat. The limit bolt passes through the horizontal plate and is threaded into the limit seat. A spring is installed between the end face of the limit seat and the end face of the extension plate.

[0007] Preferably, a threaded hole is provided at the middle position of the horizontal plate, and the horizontal plate is threadedly fitted onto the outer wall of the stirring shaft through the threaded hole. Furthermore, a limiting plate for limiting the position of the horizontal plate is provided on the outer wall of the stirring shaft above the first stirring blade, and the horizontal plate is pressed tightly against the upper end face of the limiting plate.

[0008] Preferably, a locking nut is provided on the outer wall of the stirring shaft above the horizontal plate. The locking nut is threaded onto the outer wall of the stirring shaft and pressed tightly against the upper end face of the horizontal plate. The internal thread of the locking nut is opposite in direction to the internal thread of the threaded hole.

[0009] Preferably, an inclined plate is provided at the end of the scraper away from the extension plate, the inclined plate extends to the cone part of the inner cavity of the tank, and a rubber seat is provided at the end of the scraper and the inclined plate near the inner cavity wall of the tank, the rubber seat is attached to the inner cavity wall of the tank.

[0010] Preferably, both ends of the horizontal plate are provided with openings that communicate with the slot, the extension plate extends through the openings to form the slot, and a support plate is provided at one end of the extension plate inside the slot, the end face area of ​​the support plate being larger than the opening area of ​​the opening.

[0011] Preferably, the upper end face of the horizontal plate is provided with a number of through holes evenly distributed, and the limiting bolts pass through the through holes and extend into the interior of the slot.

[0012] Preferably, the upper end face of the limiting seat is provided with a threaded groove, and one end of the limiting bolt located inside the empty groove is threaded inside the threaded groove.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] By setting up a mixing mechanism, the motor drives the stirring shaft to rotate, which in turn drives the first and second stirring blades installed on it to rotate inside the tank cavity. The first and second stirring blades stir the soybean milk in the inner cavity and its conical part, accelerating the mixing speed of soybean milk with microorganisms and oxygen, saving fermentation time and improving fermentation efficiency. At the same time, the stirring shaft drives the horizontal plate installed on it to rotate, which in turn drives the rubber scraper installed on it to move against the inner wall of the tank cavity, scraping off the soybean milk adhering to the inner wall of the tank cavity, thus achieving the purpose of cleaning the inner wall of the fermentation tank.

[0015] By setting a limiting seat and an extension plate inside the horizontal plate, and placing a spring between the limiting seat and the extension plate, the extension plate can be moved outward under the elastic force of the spring. This pushes the scraper plate installed at one end of the extension plate towards the inner wall of the tank, pressing the rubber scraper installed on the end face of the scraper plate tightly against the inner wall of the tank. This causes the rubber scraper to deform and adhere to the inner wall of the fermenter, preventing wear and tear between the rubber scraper and the inner wall of the fermenter, thus avoiding a reduction in cleaning effect due to gaps between the rubber scraper and the inner wall of the fermenter and ensuring the cleaning quality of the fermenter.

[0022] In the description of this utility model, it should be understood that the terms "center," "lateral," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not 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. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0023] Combination Figures 1-5 As shown, a motor 21 is installed at the middle position of the top of the can lid 2. A mixing mechanism 3 is installed in the inner cavity of the can body 1. The mixing mechanism 3 includes a stirring shaft 31. One end of the stirring shaft 31 extends out of the can body 1 and passes through the can lid 2 and is installed at the output end of the motor 21. Furthermore, the outer wall of the stirring shaft 31 located in the inner cavity of the can body 1 is provided with several first stirring blades 32 and second stirring blades 33 for stirring materials. A horizontal plate 34 is provided on the outer wall of the stirring shaft 31 above the second stirring blades 33. Both ends of the horizontal plate 34 are provided with slots 341. The inner... An extension plate 35 is slidably installed on the horizontal plate 34 and extends to its outside. A scraper 36 is provided at one end of the extension plate 35 outside the horizontal plate 34. The scraper 36 is attached to the inner wall of the tank body 1. A limit seat 37 is provided inside the cavity 341 on one side of the extension plate 35. A limit bolt 39 is provided at the position corresponding to the limit seat 37 on the upper part of the horizontal plate 34. The limit bolt 39 passes through the horizontal plate 34 and is threaded inside the limit seat 37. A spring 38 is installed between the end face of the limit seat 37 and the end face of the extension plate 35.

[0024] In one embodiment, when the scraper 36 is installed on the stirring shaft 31, since the internal thread of the locking nut 312 is opposite to the internal thread of the threaded hole 344, the horizontal plate 34 can be threaded onto the outer wall of the stirring shaft 31 through the threaded hole 344, so that the horizontal plate 34 is pressed tightly against the upper end face of the limiting plate 311. Then, the locking nut 312 is screwed on, so that the locking nut 312 is threaded onto the outer wall of the stirring shaft 31 and pressed tightly against the upper end face of the horizontal plate 34. The horizontal plate 34 is tightened to prevent the horizontal plate 34 from rotating on the outer wall of the stirring shaft 31. This avoids the situation where the horizontal plate 34 cannot follow the rotation of the stirring shaft 31 and drive the scraper 36 to move and clean the inner wall of the tank 1 due to the rotation of the horizontal plate 34 on the outer wall of the stirring shaft 31, thus ensuring the use of the scraper 36.

[0025] In one embodiment, when mixing soy milk and a starter culture, a drive motor 21 can be used to rotate a stirring shaft 31 mounted thereon. The rotating stirring shaft 31 then drives the first stirring blade 32 and the second stirring blade 33 mounted thereon to rotate within the inner cavity of the tank 1. This allows the first stirring blade 32 and the second stirring blade 33 to stir the soy milk within the inner cavity and its conical section, accelerating the mixing speed of the soy milk with microorganisms and oxygen, saving fermentation time, and improving fermentation efficiency. Simultaneously, the stirring shaft 31... 1. The horizontal plate 34 installed on it is rotated, and the rotating horizontal plate 34 causes the rubber scraper 362 installed on it to move against the inner wall of the tank 1, scraping off the soy milk adhering to the inner wall of the tank 1. This allows the soy milk adhering to the inner wall of the tank 1 to mix with microorganisms and oxygen, avoiding the situation where some soy milk is not in contact with microorganisms and oxygen due to adhering to the inner wall of the tank 1, which would prolong the fermentation time. This ensures the fermentation quality of the soy milk and further improves the fermentation efficiency of the soy milk.

[0026] In one embodiment, when cleaning the inner wall of the fermentation tank, the drive motor 21 can be used to rotate the stirring shaft 31 mounted thereon. The rotating stirring shaft 31 then drives the horizontal plate 34 mounted thereon to rotate, causing the rotating horizontal plate 34 to move and scrape the soy milk adhering to the inner wall of the tank 1 through the scraper plate 36. This achieves the purpose of cleaning the inner wall of the fermentation tank. At the same time, the inclined plate 361 mounted on the scraper plate 36 drives the rubber scraper 362 to move and scrape the soy milk adhering to the inner wall of the cone part of the inner cavity of the tank 1, further improving the cleaning effect of the inner wall of the fermentation tank.

[0027] In one embodiment, when using the rubber scraper 362 to clean the inner cavity of the fermenter, the extension plate 35 in the slot 341 can be moved from the opening 342 to the outside of the horizontal plate 34 under the action of the spring 38, and push the scraper 36 installed at one end of the extension plate 35 to move towards the inner wall of the tank body 1, pressing the rubber scraper 362 installed on the end face of the scraper 36 tightly against the inner wall of the tank body 1, so that the rubber scraper 362 deforms and fits against the inner wall of the fermenter, preventing the rubber scraper 362 from wearing and creating gaps between it and the inner wall of the fermenter, avoiding the situation where the cleaning effect is reduced due to gaps between the rubber scraper 362 and the inner wall of the fermenter, and ensuring the cleaning quality of the fermenter.

[0028] In one embodiment, when the spring 38 experiences elastic fatigue, the extension plate 35 can be pulled from the through-hole 342, causing the extension plate 35 to move the limiting seat 37 connected to it via the spring 38 in the slot 341. The position of the limiting seat 37 is adjusted so that the threaded groove 371 corresponds to the position of the through hole 343. Then, the limiting bolt 39 is inserted into the through hole 343 and tightened to install the limiting bolt 39 in the threaded groove 371, thus limiting the position of the limiting seat 37 after adjustment and shortening the distance between the limiting seat 37 and the extension plate 35, and the inner wall of the tank 1. The compression spring 38 increases the elasticity of the spring 38, preventing the rubber scraper 362 mounted on the extension plate 35 through the scraper plate 36 from failing to adhere to the inner wall of the tank 1 due to insufficient elasticity of the spring 38. This ensures the usability of the rubber scraper 362. Furthermore, when the stirring shaft 31 is removed from the tank 1 to adjust the position of the limiting seat 37, the end face area of ​​the support plate 351 is larger than the opening area of ​​the through port 342. The support plate 351 can limit the extension plate 35, preventing the extension plate 35 from detaching from the horizontal plate 34, thus ensuring the usability of the extension plate 35.

[0029] The working principle of this invention is as follows: During the fermentation of soy milk, the drive motor 21 rotates the stirring shaft 31 mounted on it. The rotating stirring shaft 31 then drives the first stirring blade 32 and the second stirring blade 33 mounted on it to rotate within the inner cavity of the tank 1. This allows the first stirring blade 32 and the second stirring blade 33 to stir the soy milk within the inner cavity and its conical section, accelerating the mixing speed of the soy milk with microorganisms and oxygen, saving fermentation time, and improving fermentation efficiency. Simultaneously, the stirring shaft 31... 1. The horizontal plate 34 installed on it is rotated, and the rotating horizontal plate 34 drives the rubber scraper 362 installed on it through the scraper plate 36 to move against the inner wall of the tank 1, scraping off the soy milk adhering to the inner wall of the tank 1. This allows the soy milk adhering to the inner wall of the tank 1 to mix with microorganisms and oxygen, avoiding the situation where some soy milk is not in contact with microorganisms and oxygen due to adhering to the inner wall of the tank 1, which would lead to a prolonged fermentation time. This ensures the fermentation quality of the soy milk and further improves the fermentation efficiency of the soy milk.

[0030] When cleaning the fermentation tank, the drive motor 21 rotates the stirring shaft 31 mounted on it. The rotating stirring shaft 31 then rotates the horizontal plate 34 mounted on it. The rotating horizontal plate 34 causes the rubber scraper 362 mounted on it, which is connected to the inner wall of the tank body 1 and the inner wall of the conical part of the inner cavity, to move and scrape off the soybean milk adhering to the inner wall of the tank body 1, thereby cleaning the inner wall of the fermentation tank. At the same time, the extension plate 35 is moved horizontally under the action of the spring 38. The external movement of plate 34 pushes the scraper 36 installed at one end of extension plate 35 toward the inner wall of tank 1, pressing the rubber scraper 362 installed on the end face of scraper 36 tightly against the inner wall of tank 1. This causes the rubber scraper 362 to deform and adhere to the inner wall of the fermenter, preventing wear and tear between the rubber scraper 362 and the inner wall of the fermenter, thus avoiding a reduction in cleaning effect due to gaps between the rubber scraper 362 and the inner wall of the fermenter. This ensures the cleaning quality of the fermenter and is highly practical.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
