Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of soybean product production, and in particular to a soybean soaking tank. This utility model also relates to a soybean product pretreatment device including the aforementioned soybean soaking tank. Background Technology
[0002] Soybean soaking tanks are specialized equipment used in the production of soy products for the pretreatment of raw soybeans. Their main function is to soften the soybean's structure through water soaking, promoting the dissolution of proteins and polysaccharides, thereby improving the efficiency of subsequent grinding and separation processes. Traditional soybean soaking tanks typically consist of a cylindrical tank, a water inlet / drainage system, and basic temperature control devices. While their design is based on the fundamental principles of hydration, practical applications must also consider hygiene, ease of operation, and energy efficiency. With the increasing demand for industrialized soy product production, structural optimization and functional improvement of existing soaking tanks have become important directions for technological upgrading in the industry.
[0003] Existing soybean soaking tanks typically use stainless steel bodies and are equipped with internal stirring blades or vortex generators to achieve uniform soaking. Some models also integrate heating modules and water level sensors for precise control of water temperature and level. This equipment combines physical soaking with mechanical assistance to promote full water absorption and expansion of soybeans, shortening the soaking cycle and improving the uniformity of soybean softening. Its applications mainly cover large-scale production lines for soy products such as soy milk, tofu, and dried bean curd. However, after long-term operation, the soybean skins on the surface of existing equipment tend to adhere to the inner wall of the tank during soaking, forming stubborn residues. This soybean skin adhesion problem is mainly caused by the physical adsorption effect between the polysaccharides rich in soybean skins and the metal surface of the tank. As the soaking time increases, the adhesion layer gradually thickens, not only hindering the uniformity of water circulation within the tank but also leaving a large amount of soybean skin debris after drainage, requiring frequent shutdowns for manual cleaning, which seriously affects the production efficiency of the soybean soaking tank.
[0004] In existing technologies, some technical solutions attempt to alleviate this problem by increasing the polishing level of the inner wall or optimizing the stirring intensity, but the actual effect is still limited. Therefore, existing soybean soaking tanks have the technical problem of soybean skin residue adhering to the inner wall of the container, resulting in a decrease in production efficiency. Utility Model Content
[0005] In view of this, the present invention aims to provide a soybean soaking tank and a soybean product pretreatment device, which can effectively improve the phenomenon of soybean skin residue adhering to the inner wall of the container, thereby improving the production efficiency of the soybean soaking tank.
[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0007] A soybean soaking tank, comprising a first tank body;
[0008] A stirring assembly is disposed within the first tank.
[0009] Heating components are wrapped around the outside of the first tank body;
[0010] The stirring assembly includes a geared motor, which is disposed at the top of the first tank;
[0011] The main shaft is rotatably mounted on the first tank along the axial direction of the first tank, and one end is connected to the geared motor;
[0012] The stirring rod is configured in a U-shape distributed along the inner wall of the first tank.
[0013] A scraper is rotatably mounted on the stirring rod, and its edge abuts against the inner wall of the first tank.
[0014] Furthermore, the stirring assembly also includes a connecting rod, which is arranged in a direction perpendicular to the axis of the first tank, and its two ends are respectively fixedly connected to the stirring rod and the main shaft.
[0015] Furthermore, the top of the first tank has an opening;
[0016] A cover plate is rotatably provided on one end of the first tank body near the opening, and / or,
[0017] A detachable guide plate is provided on one end of the first tank near the opening.
[0018] Furthermore, the heating assembly includes a second tank, which is sleeved on the outside of the first tank, forming a heating space between the first tank and the second tank;
[0019] A heating element is disposed within the heating space, located below the first tank body;
[0020] A water injection pipe is installed at the top of the second tank and communicates with the interior of the heating space;
[0021] A drain pipe is installed at the bottom of the second tank and communicates with the interior of the heating space.
[0022] Furthermore, the heating assembly also includes a pressure relief valve, which is installed on the second tank body, with its two ends connected to the heating space and the outside world, respectively.
[0023] Furthermore, temperature sensors are installed on the side walls of both the first and second tanks;
[0024] A shield is provided on the outer side of the temperature sensor along the axial direction.
[0025] Furthermore, it also includes a third tank body, which is fitted onto the outside of the second tank body;
[0026] The bottom of the third tank is provided with multiple support legs, which are evenly distributed on the bottom surface of the third tank.
[0027] This invention relates to a soybean soaking tank, which comprises a first tank body, a stirring assembly, and a heating assembly. The first tank body serves as the main container for soaking soybeans, while the stirring and heating assemblies respectively stir and heat the soybeans within it, thus ensuring the efficiency of the soaking process. A geared motor in the stirring assembly drives the main shaft to rotate. The main shaft supports and limits the stirring rod, while also transmitting the torque of the geared motor. Driven by the main shaft, the stirring rod rotates, stirring the soaking soybeans and improving the extraction rate while shortening the soaking time. A scraper mounted on the stirring rod scrapes against the inner wall of the first tank body during the stirring process, preventing soybean skins from adhering to the inner wall and thus achieving the invention's objective of increasing the production efficiency of the soybean soaking tank.
[0028] Secondly, by installing a rotatable cover on the first tank, the opening at the top of the tank can be sealed, preventing debris from falling in during soybean soaking. By installing an inclined guide plate on the first tank, the soybeans can be guided during feeding, reducing material spillage. Furthermore, by designing the guide plate as a snap-fit, detachable structure, it can be prevented from obstructing the opening or closing of the cover.
[0029] Furthermore, by configuring the heating assembly as a structure consisting of a second tank, heating pipes, a water injection pipe, a drain pipe, and a pressure relief valve, the outer walls of the second tank and the first tank enclose a heating space for water bath heating of the first tank, while also providing support and restraint for the installation of other parts of the heating assembly. The heating pipes achieve comprehensive and uniform heating of the first tank by raising the temperature of the water within the heating space. The water injection pipe and drain pipe are used to add water to the heating space and to drain wastewater from the heating space, respectively. The pressure relief valve maintains the air pressure within the heating space within a safe range, improving the overall safety of the equipment.
[0030] This utility model also includes a soybean product pretreatment device, which uses the soybean soaking tank as described above.
[0031] The technical effects that the soybean soaking tank of this utility model can achieve in the pretreatment equipment for soybean products are the same as those that the existing technology can achieve compared with the soybean soaking tank, and will not be described again here.

[0043] The following will refer to the appendix. Figure 1 To be continued Figure 4 The present invention will be described in detail with reference to the embodiments.
[0044] Example 1
[0045] This embodiment relates to a soybean soaking tank, which is adopted.
[0046] In terms of overall structure, refer to Figure 1 , Figure 2 and Figure 3 The soybean soaking tank of this embodiment includes a first tank body 1, a stirring assembly 2, and a heating assembly 3. The first tank body 1 can be a hollow cylindrical stainless steel tank with an open top. The stirring assembly 2 is installed inside the first tank body 1, and the heating assembly 3 covers the outside of the first tank body 1. The stirring assembly 2 includes a geared motor 201, a main shaft 202, a stirring rod 203, and scrapers 204. The geared motor 201 is installed on the top of the first tank body 1, and the main shaft 202 is rotatably mounted on the first tank body 1 along its axial direction. One end of the main shaft 202 is connected to the power output end of the geared motor 201 via a coupling. The other end of the main shaft 202 is connected to the stirring rod 203. The stirring rod 203 is constructed as a U-shaped rod distributed along the inner wall of the first tank body 1. Multiple scrapers 204 are rotatably mounted on the stirring rod 203. The edges of the scrapers 204 abut against the inner wall of the first tank body 1.
[0047] By configuring the soybean soaking tank into a structure consisting of a first tank body 1, a stirring assembly 2, and a heating assembly 3, the first tank body 1 serves as the main container for soybean soaking. The stirring assembly 2 and the heating assembly 3 respectively stir and heat the soybeans within the first tank body 1, thereby ensuring the efficiency of the soaking process. The geared motor 201 in the stirring assembly 2 drives the main shaft 202 to rotate. The main shaft 202 supports and limits the stirring rod 203, while also transmitting the torque of the geared motor 201. Driven by the main shaft 202, the stirring rod 203 rotates, stirring the soaking soybeans, which helps improve the extraction rate and shorten the soaking time. The scraper 204 installed on the stirring rod 203 scrapes against the inner wall of the first tank body 1 during the stirring process, helping to prevent soybean skins from adhering to the inner wall of the first tank body 1, thus achieving the invention's objective of improving the production efficiency of the soybean soaking tank.
[0048] Reference Figure 1 , Figure 2 and Figure 3 A connecting rod 205 is horizontally arranged between the stirring rod 203 and the main shaft 202. The connecting rod 205 can be a hollow metal rod with flat ends. Both ends of the connecting rod 205 are fixedly connected to the main shaft 202 of the stirring rod 203. By setting the connecting rod 205 between the main shaft 202 and the stirring rod 203, it can, on the one hand, cooperate with the stirring rod 203 to stir the soybeans, achieving a more uniform stirring effect; on the other hand, it can increase the structural strength and deformation resistance of the stirring rod 203, so that the scraper 204 installed on the stirring rod 203 can maintain abutment and fit against the inner wall of the first tank 1, ensuring the scraping effect.
[0049] Reference Figure 1 and Figure 2 The first tank 1 has an open top. A cover plate 101 can be installed on the end of the first tank 1 near the open top. The cover plate 101 is mounted on the first tank 1 by a rotatable connection. A guide plate 102 can also be installed on the end of the first tank 1 near the open top. The guide plate 102 is detachably mounted on the first tank 1 by a snap-fit connection, and the guide plate 102 is inclined. A discharge pipe is provided at the bottom of the first tank 1, and a ball valve is installed on the discharge pipe to control the opening and closing of the discharge pipe.
[0050] By installing a rotatable cover plate 101 on the first tank 1, the opening at the top of the first tank 1 can be sealed, preventing debris from falling in during soybean soaking. By installing an inclined guide plate 102 on the first tank 1, the soybeans can be guided during feeding, which helps reduce material spillage. By setting the guide plate 102 as a snap-fit detachable structure, the guide plate 102 can be prevented from obstructing the opening or closing of the cover plate 101.
[0051] Reference Figure 1 , Figure 2 and Figure 4 The heating assembly 3 includes a second tank 301, a heating pipe 302, a water injection pipe 303, a drain pipe 304, and a pressure relief valve 305. The second tank 301 can be a cylindrical hollow metal tank with a diameter larger than that of the first tank 1. The second tank 301 is fitted over the outside of the first tank 1, forming a heating space between them. The heating pipe 302 is installed within the heating space. The heating pipe 302 is horizontally positioned below the first tank 1. One end of the heating pipe 302 extends to the outside of the second tank 301 and heats up when energized. To improve heating efficiency and uniformity, multiple sets of heating pipes 302 can be arranged in parallel and at equal intervals. The water injection pipe 303 passes through the top of the second tank 301 and communicates with the interior of the heating space. The drain pipe 304 passes through the bottom of the second tank 301 and communicates with the interior of the heating space. The pressure relief valve 305 is installed on the second tank 301, and its two ends are connected to the interior of the heating space and the external environment, respectively. When the air pressure inside the heating space reaches the set value of the pressure relief valve 305, the two ends of the pressure relief valve 305 are connected, and the air pressure inside the heating space drops.
[0052] By configuring the heating assembly 3 into a structure consisting of a second tank 301, a heating pipe 302, a water injection pipe 303, a drain pipe 304, and a pressure relief valve 305, the second tank 301 and the outer wall of the first tank 1 enclose a heating space for water bath heating of the first tank 1, while also providing support and limiting for the installation of other parts of the heating assembly 3. The heating pipe 302 can achieve comprehensive and uniform heating of the first tank 1 by heating the water in the heating space. The water injection pipe 303 and the drain pipe 304 are used to add water to the heating space and drain wastewater from the heating space, respectively. The pressure relief valve 305 can maintain the air pressure in the heating space within a safe range, improving the overall safety of the equipment.
[0053] Reference Figure 1 and Figure 2Temperature sensors 4 are installed on the side walls of both the first tank 1 and the second tank 301. The temperature sensing end of each temperature sensor 4 is located inside the first tank 1 or the second tank 301, and is used to measure the internal temperature of the first tank 1 or the second tank 301, converting it into an electrical signal for easy reading. A protective cover is provided on the outside of the temperature sensor 4, which covers the outer ring of the temperature sensor 4 to help prevent the portion of the sensor exposed outside the first tank 1 or the second tank 301 from physical damage such as impacts.
[0054] Reference Figure 1 and Figure 2 In this embodiment, the soybean soaking tank also includes a third tank body 5, which covers the outside of the second tank body 301. Multiple support legs 501 are installed at the bottom of the third tank body 5, and these support legs 501 are evenly distributed at equal intervals on the bottom surface of the third tank body 5. The third tank body 5, covering the outside of the second tank body 301, reduces heat loss from the heating component 3, lowering equipment energy consumption. Furthermore, its top can be used to assist in supporting and securing other parts of the soybean soaking tank structure. The support legs 501 at the bottom of the third tank body 5 provide overall support for the equipment.
