Description

Technical Field

[0001] This utility model relates to the technical field of soybean product processing equipment, specifically a soybean product coagulation device that facilitates stirring. Background Technology

[0002] Soy products are common and nutritious foods in people's daily lives. The production of soy products such as soy milk, tofu, dried tofu, and fermented tofu generally involves seven main steps: selecting soybeans, soaking soybeans, grinding soybeans, filtering the soy milk, boiling the soy milk, adding coagulant, and shaping. Specifically, in the production process, high-quality soybeans are first selected, soaked, and then ground into a soy milk. A coagulant, such as brine, is then used to coagulate the soy milk into tofu curds. The tofu curds are transferred to molding molds and then pressed into tofu or further processed into dried tofu. The coagulation process is the mixing and reaction of the soy milk and the coagulant in the soy product processing, and it is also a crucial step in the soy product production process. A certain amount of soy milk is coagulated with an appropriate amount of coagulant. Then, process parameters such as soy milk concentration, brine concentration, soy milk-brine ratio, stirring method, and coagulation temperature are controlled. The coagulation process is completed by a soy product coagulation device, and the quality of the coagulation process directly affects the yield and quality of the soy products.

[0003] While existing improvement solutions have introduced electric stirring or insulation structures, they still have significant shortcomings. Some devices use a design that separates the fixed stirring arm from the tank, but the stirring only relies on unidirectional rotation, resulting in limited mixing uniformity. Some devices have added a coagulant spraying function, but the spraying position is fixed and cannot be coordinated with the stirring action, resulting in uneven distribution of the coagulant. Utility Model Content

[0004] The purpose of this invention is to provide a bean curdling device that facilitates stirring, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bean curdling device for easy stirring, comprising a base plate and a curdling tank, the curdling tank being fixedly installed in the middle of the base plate, the top opening of the curdling tank being provided with a cover plate through a sealing assembly, the cover plate being provided with a curdling mixing mechanism, the base plate being symmetrically provided with vertical plates at both ends of the curdling tank, the vertical plates being connected to the cover plate through an adjustment mechanism.

[0006] Preferably, in order to facilitate the mixing and stirring of the soy product slurry and to facilitate mixing with the coagulant, the slurry mixing mechanism includes a motor fixedly installed at the top center of the cover plate, a rotating rod fixedly installed at the output end of the motor, and a stirring rod installed at equal intervals inside the cover plate through the rotating rod.

[0007] Preferably, in order to facilitate the addition of coagulant and to facilitate the distribution of coagulant in various layers of the soy product slurry, and to facilitate mixing and distribution, the slurry mixing mechanism also includes liquid filling pipes symmetrically arranged on the cover plate at both ends of the rotating rod. The top of the liquid filling pipe is open, and the liquid filling pipe passes through the cover plate and extends downwards with liquid outlets at equal intervals.

[0008] Preferably, in order to facilitate the rotation of the rotating rod and the liquid filling pipe at the same time, and to facilitate the distribution of coagulant in conjunction with the liquid outlet, and to assist in mixing, a main gear is fixedly provided at the output end of the motor, and a driven gear that meshes with the main gear is fixedly provided on the top circumferential side of the liquid filling pipe.

[0009] Preferably, in order to ensure a sealing effect when the cover is closed, the sealing assembly includes a sealing ring fixedly disposed at the bottom of the cover, and a sealing groove that is interference-fitted with the sealing ring is provided at the top opening end of the slurry tank.

[0010] Preferably, in order to facilitate the up-and-down movement of the cover plate and to facilitate use and subsequent removal and cleaning operations, the adjustment mechanism includes a through groove in the middle of the vertical plate, an electric push rod fixedly installed in the through groove, a connecting block fixedly installed at the output end of the electric push rod, and the connecting block fixedly connected to the cover plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The included mixing mechanism allows for easy mixing of the soy product slurry before coagulation, ensuring thorough and uniform mixing. It also guarantees even heating during the heating process. When coagulant needs to be added, the coagulant can be easily added through the filling pipe and outlet. The addition process is assisted by rotation to ensure that the coagulant is evenly distributed inside the soy product slurry, without affecting subsequent static coagulation, thus ensuring product quality. At the same time, it shortens the mixing time and improves mixing efficiency.

[0014] With the adjustment mechanism and sealing components, the cover plate can be easily moved up and down. On the one hand, it is convenient to move the cover plate down and reset during use, while ensuring the sealing effect with the sealing components, so as not to affect the processing and use. On the other hand, after use, the slurry mixing mechanism under the cover plate can be easily removed for cleaning or maintenance, which is relatively convenient. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-5This utility model provides an embodiment of a bean curdling device for easy stirring, comprising a base plate 1, with a curdling tank 2 installed in the middle of the base plate 1. The curdling tank 2 is used for curdling bean products. The tank body of the curdling tank 2 may be equipped with an internal heat-insulating device. Specifically, the tank body of the curdling tank 2 may be double-layered, with an inner layer of food-grade stainless steel (304 material) and an outer layer of heat-insulating material (such as polyurethane), or other materials may be used. A heating device (which can be implemented by electric heating, etc.) is provided between the two layers to ensure the internal temperature does not affect the curdling process of the bean products, as needed. The opening end of the curdling tank 2 has a sealing groove 4 for a sealing component, and a sealing ring 11 is glued to the bottom of the corresponding cover plate 5. The cover plate 5 can be easily sealed by an interference fit with the sealing groove 4 when covered. A motor 6 for a slurry mixing mechanism is located at the top center of the cover plate 5 (it can be connected and fixed to the cover plate 5 via a mounting bracket and screws, not shown in the figure, to ensure the stability of the motor 6). A rotating rod 12 is fixedly connected to the output end of the motor 6 via a coupling. The rotating rod 12 passes through the cover plate 5 and extends downwards where stirring rods 13 (or mixing blades, etc.) are installed at equal intervals. A liquid-adding pipe 14 is symmetrically located at both ends of the rotating rod 12 on the cover plate 5. The top of the liquid-adding pipe 14 is open (for easy addition of coagulant). Liquid outlets 15 are equidistantly opened on the bottom of the liquid-adding pipe 14, and are connected to the liquid-adding pipe 14. To facilitate the distribution of coagulant across all layers of the slurry and ensure uniform mixing during subsequent stirring, thus preventing the formation of undercooked layers, a main gear 16 is installed at the output end of the motor 6 to ensure even distribution, while the rotating rod 12 rotates along with the filling pipe 14. A driven gear 17, meshing with the main gear 16, is installed on the circumferential side of the top end of the filling pipe 14. This allows the motor 6 to rotate along with the rotating rod 12, simultaneously rotating the filling pipe 14 and aiding in the uniform distribution of the coagulant.

[0023] Please see Figures 1-5To facilitate the up-and-down movement of the cover plate 5 and the removal of the slurry mixing mechanism after mixing without affecting slurry solidification, and to facilitate cleaning, the vertical plate 3 is connected to the cover plate 5 via an adjustment mechanism, allowing the cover plate 5 to move up and down as a whole. The adjustment mechanism includes a through groove 19 in the middle of the vertical plate 3. An electric push rod 7 is vertically mounted on the base plate 1 at the through groove 19. A connecting block 8, which allows for easy up-and-down movement within the through groove 19, is installed at the output end of the electric push rod 7. The end of the connecting block 8 is fixedly connected to the cover plate 5 (via screws). (For nail installation and fixation), in order to ensure stability during the up and down movement and avoid swaying or displacement, the vertical plate 3 is also symmetrically provided with auxiliary grooves 20 (rectangular cross-section) on both sides of the through groove 19. The auxiliary plate 9 is slidably fitted inside the auxiliary groove 20. The end of the auxiliary plate 9 is fixedly connected to the cover plate 5 (which can be fixed by screws). Guide blocks 10 are also symmetrically welded on both sides of the auxiliary plate 9. The inner wall of the auxiliary groove 20 is provided with guide grooves 18 to facilitate the up and down sliding of the guide blocks 10, which can play a guiding and limiting role to ensure the stability of the up and down movement.

[0024] Working Principle: In use, the motor 6 drives the rotating rod 12 and stirring rod 13 to rotate. Simultaneously, the main gear 16 rotates, engaging with the driven gear 17 to rotate the liquid addition pipe 14. This mixes and stirs the soybean product slurry inside the coagulation tank 2. When coagulation is needed, the coagulant is added through the liquid addition pipe 14, then flows out through the outlets 15 on the pipe 14, dispersing into the soybean product slurry. The motor 6 continues to operate, mixing the coagulant with the soybean product slurry to ensure uniform distribution and not affecting the subsequent static coagulation effect. The stirring speed and time can be: high speed... Stirring (150 rpm, 2 minutes) followed by low-speed hold-up (50 rpm, 5 minutes). The appropriate time and speed can be selected according to different situations. This is a relatively mature technology and will not be elaborated here. When it is necessary to remove the cover plate 5 for cleaning, the motor 6 stops working. Then, the electric push rod 7 extends and moves the connecting block 8 upward in the through groove 19, moving the cover plate 5 upward as a whole. The sealing ring 11 leaves the sealing groove 4. At the same time as it moves upward, the auxiliary plate 9 moves upward in the auxiliary groove 20, and the guide block 10 slides in the guide groove 18 to ensure stability during the upward movement. This makes it easy to remove the cover plate 5 as a whole for subsequent cleaning.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
