Description

Technical Field

[0001] This utility model relates to the field of food fermentation technology, and in particular to a soybean soaking device for microbial fermentation in soy sauce processing. Background Technology

[0002] Soy sauce is a traditional Chinese condiment, a liquid made from soybeans, wheat, and wheat bran. It has a reddish-brown color, a unique soy aroma, and a delicious flavor, which helps to stimulate appetite. The soy sauce research and development process is divided into six major steps: selecting soybeans, steaming soybeans, cooling, making koji, adding ingredients, and extracting oil. Among these, the selection, soaking, and fermentation of soybeans is a crucial step.

[0003] An existing patent (publication number: CN210974641U) discloses a soybean fermentation device. Through a set of screening, soaking, and fermentation devices, it can achieve integrated production from screening and soaking to fermentation of soybeans. It is simple to operate, highly automated, and controls the fermentation temperature of soybeans, thereby improving the product yield. However, in the process of implementing this solution, the following problems were found in the existing technology, which have not been adequately resolved:

[0004] The equipment achieves the soaking effect through the main and auxiliary soaking tanks. However, during use, the soybeans at the bottom are not easy to float upwards, resulting in limited screening effect. Furthermore, soybeans that are not plump enough are also prone to enter the subsequent fermentation process, affecting the quality of the final soy sauce product. Utility Model Content

[0005] To address the aforementioned problem that soybeans at the bottom cannot float upwards and smaller soybeans cannot be screened, this invention provides a soybean soaking device for microbial fermentation in soy sauce processing.

[0006] This utility model provides a soybean soaking device for microbial fermentation in soy sauce processing, which adopts the following technical solution:

[0007] A soybean soaking device for microbial fermentation in soy sauce processing includes a main body, a screening mechanism above the main body, a soaking chamber below the screening mechanism, a fermentation mechanism below the soaking chamber, a feed inlet above the soaking chamber, a first filter screen below the feed inlet, a movable plate connected below the first filter screen, a stirring rod inside the first filter screen, and a fixed rod connected to the center of the stirring rod.

[0008] A second filter screen is connected to the outside of the first filter screen, an electric push rod is connected to the top of the second filter screen, a support frame is connected to the outside of the second filter screen, a base plate is connected to the bottom of the support frame, anti-detachment blocks are connected to both sides of the base plate, and a discharge port is provided at the bottom of the base plate.

[0009] The above technical solution facilitates the use of the first filter screen in conjunction with the stirring rod to ensure stirring during the soaking process, thereby separating impurities and small pieces of soybeans and ensuring the quality of the final product. Furthermore, the inclusion of a bottom plate and anti-detachment blocks allows for the collection of impurities, ensuring rapid removal of impurities.

[0010] Optionally, in the above-mentioned soybean soaking equipment for microbial fermentation in soy sauce processing, a driving mechanism is provided above the bottom of the soaking chamber, and the driving mechanism can drive the movable plate to rotate. The movable plate and the first filter screen have an integrated rotating structure.

[0011] The above technical solution facilitates the rotation of the movable plate and the first filter screen by driving the drive mechanism, which in turn facilitates the agitation of water flow and the rapid drying of soybeans.

[0012] Optionally, in the above-mentioned soybean soaking equipment for microbial fermentation in soy sauce processing, the fixed rods are symmetrically distributed on both sides of the upper part of the soaking chamber, and stirring rods are evenly and equidistantly distributed on both sides of the fixed rods, with the bottom of the stirring rods attached to the top of the movable plate.

[0013] The above technical solution facilitates the use of a fixed rod and a stirring rod to stir soybeans, ensuring that soybeans and impurities at the bottom float upwards, thus improving the soaking and cleaning effect.

[0014] Optionally, in the above-mentioned soybean soaking equipment for microbial fermentation in soy sauce processing, the pore size of the first filter screen is larger than that of the second filter screen, the length of the second filter screen is the same as that of the first filter screen, and the connection between the second filter screen and the first filter screen is a sliding connection.

[0015] The above technical solution facilitates the use of a second filter to block the first filter, preventing the plump soybeans from separating out with the first filter.

[0016] Optionally, in the above-mentioned soybean soaking equipment for microbial fermentation in soy sauce processing, the electric push rods are symmetrically distributed above the skeleton of the second filter screen, the electric push rods and the second filter screen form an integrated lifting structure, and the connection between the skeleton and the support frame is a heat fusion connection.

[0017] The above technical solution facilitates the use of an electric push rod in conjunction with the second filter screen, enabling the second filter screen to automatically rise and fall, ensuring that soybeans are ejected when needed.

[0018] Optionally, in the above-mentioned soybean soaking equipment for microbial fermentation in soy sauce processing, the support frame and the base plate are installed as an integral unit, anti-detachment blocks are symmetrically distributed on both sides of the upper part of the base plate, a groove is provided on the left side of the anti-detachment block, and a sealing rubber ring is connected to the lower part of the base plate.

[0019] The above technical solution facilitates the use of the base plate and anti-detachment block to prevent water from flowing downwards and to collect impurities.

[0020] In summary, this utility model has at least one of the following beneficial effects:

[0021] The first filter screen is installed inside the soaking chamber in conjunction with a stirring rod. During use, the first filter screen rotates the soybeans and continuously stirs them with the stirring rod, causing small soybean particles and impurities at the bottom to float out through the first filter screen. After use, the second filter screen is lifted, allowing the plump soybeans to be fed through the feeding port, ensuring the screening of soybeans.

[0022] A support frame and a base plate are connected to the outside of the second filter screen. The support frame and the base plate rise and fall with the second filter screen. During soaking, impurities and small soybeans stay above the base plate. When the soybeans are being fed, the base plate rises, so as not to affect the feeding of soybeans.

[0028] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0029] Please refer to the attached diagram in the instruction manual. Figure 1-4This utility model provides an embodiment of a soybean soaking device for microbial fermentation in soy sauce processing, comprising a main body 1, a screening mechanism 2 above the main body 1, a soaking chamber 4 below the screening mechanism 2, for soaking soybeans in the soaking chamber 4 to ensure subsequent fermentation, a fermentation mechanism 3 below the soaking chamber 4, a feed inlet 5 above the soaking chamber 4, a first filter screen 10 below the feed inlet 5 for filtering small soybeans and impurities, a movable plate 9 connected below the first filter screen 10, a stirring rod 7 inside the first filter screen 10 for stirring soybeans, and a fixed rod 6 connected to the center of the stirring rod 7;

[0030] A second filter 12 is connected to the outside of the first filter 10. An electric push rod 11 is connected to the top of the second filter 12. The electric push rod 11 provides power for the automatic lifting and lowering of the second filter 12. A support frame 13 is connected to the outside of the second filter 12. A base plate 14 is connected to the bottom of the support frame 13. The base plate 14 cooperates with the anti-detachment block 15 to collect impurities and small soybean particles. Anti-detachment blocks 15 are connected to both sides of the base plate 14. A discharge port 8 is provided at the bottom of the base plate 14.

[0031] Working principle: In use, firstly, soybeans are placed into the body 1 of the equipment from the bottom. After being screened by the screening mechanism 2, they enter the soaking chamber 4 through the feed inlet 5. At this time, the soybeans are inside the first filter screen 10 and above the movable plate 9. Water is injected into the soaking chamber 4 through the inlet and outlet. At the same time, the drive switch below the movable plate 9 is turned on, so that the movable plate 9 starts to drive the first filter screen 10 to rotate. Then the soybeans and water flow start to rotate. During the rotation, they are constantly disengaged from the stirring rod 7. After the impurities and small soybean particles are filtered by the first filter screen 10 and the second filter screen 12, they float above the bottom plate 14. Then the water flow is drawn out through the inlet and outlet pipes. The anti-detachment block 15 is also equipped with a filter screen at the connection between it and the inlet and outlet pipes. At this time, the impurities and soybeans remain above the bottom plate 14.

[0032] As described above, the switch of the electric push rod 11 is then turned on, causing the second filter screen 12 to rise. At the same time, the second filter screen 12 drives the bottom plate 14 and the anti-detachment block 15 to rise through the support frame 13. At this time, because the second filter screen 12 separates from the first filter screen 10, as the first filter screen 10 continues to swing, large particles are thrown out of the first filter screen 10, and the bottom plate 14 separates from the feed port 8. Thus, large pieces of soybeans enter the fermentation mechanism 3 below through the feed port 8 for fermentation.

[0033] It should be noted that the specific parts and connection relationships of the fermentation mechanism 3 and the screening mechanism 2 can be found in the corresponding patents in the background art.

[0034] It should be noted that a drive mechanism is provided above the bottom of the soaking chamber 4, and the drive mechanism can drive the movable plate 9 to rotate. The movable plate 9 and the first filter screen 10 are integrated rotating structures. The drive mechanism drives the movable plate 9 and the first filter screen 10 to rotate, which facilitates the stirring of water flow and the rapid drying of soybeans.

[0035] It should be noted that the fixed rods 6 are symmetrically distributed on both sides of the upper part of the soaking chamber 4, and the stirring rods 7 are evenly distributed on both sides of the fixed rods 6. The bottom of the stirring rods 7 is attached to the top of the movable plate 9. The fixed rods 6 and the stirring rods 7 work together to stir the soybeans, ensuring that the soybeans and impurities at the bottom float upwards, thus improving the soaking and cleaning effect.

[0036] It should be noted that the aperture of the first filter screen 10 is larger than that of the second filter screen 12, the length of the second filter screen 12 is the same as that of the first filter screen 10, and the second filter screen 12 is connected to the first filter screen 10 by a sliding connection. The second filter screen 12 is used to block the first filter screen 10, so as to prevent the plump soybeans from separating out with the first filter screen 10.

[0037] It should be further explained that the electric push rods 11 are symmetrically distributed above the frame of the second filter screen 12. The electric push rods 11 and the second filter screen 12 form an integrated lifting structure, and the frame and the support frame 13 are connected by heat fusion. By using the electric push rods 11 and the second filter screen 12 in conjunction, the second filter screen 12 can be automatically raised and lowered to ensure that soybeans are thrown out when needed.

[0038] It should be noted that the support frame 13 and the base plate 14 are installed as a single unit. Anti-detachment blocks 15 are symmetrically distributed on both sides of the upper part of the base plate 14. A groove is provided on the left side of the anti-detachment block 15. A sealing rubber ring is connected to the lower part of the base plate 14. The base plate 14 and the anti-detachment block 15 cooperate to prevent water from flowing downwards and to collect impurities.

[0039] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
