Description

Technical Field

[0001] This utility model belongs to the field of filtration device technology, and more specifically, it relates to a filtration device for tofu production. Background Technology

[0002] Tofu is an ancient food and a common food in daily life. Tofu is made from soybeans. After grinding soybeans, soy milk is produced. Soy milk contains soy pulp. Only by filtering and separating the soy pulp from the soy milk can you get smooth tofu.

[0003] A search revealed that Chinese utility model patent CN202321718383.7 provides a filtration device for tofu production. When using this device, the operator can place the mounting frame containing the raw material to be filtered between four limiting posts using a handle. The limiting posts facilitate quick loading, unloading, and positioning of the mounting frame, preventing it from shaking and reducing filtration efficiency. When the tofu's own weight causes the filter cloth to sink, the symmetrically distributed adjusting rods on the rotating platform support the filter cloth. The drive motor, via a rotating shaft, drives gear two in both forward and reverse directions, causing the sliding frame to move left and right reciprocally. This, in turn, causes the rotating platform to drive the adjusting rods to move left and right reciprocally, evenly agitating the raw material. Furthermore, during this process, gear one at the lower end of the outer arc surface of the rotating platform's shaft meshes with a rack plate, causing the rotating platform itself to rotate as it moves the adjusting rods left and right, improving the agitation and filtration efficiency. However, this device does not shield the filter cloth during filtration, leaving the soy milk directly exposed to the air. In poor production environments, this can lead to hygiene problems in tofu production, affecting product quality and safety. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a filtration device for tofu production. This addresses the issue that existing tofu production filtration devices are directly exposed to the air during the filtration of soy milk, which can lead to hygiene problems and affect product quality when the production environment is unfavorable.

[0005] The purpose and function of this utility model's filtration device for tofu production are achieved through the following specific technical means:

[0006] A filtration device for tofu production includes a separation tank with a separation chamber inside. A mounting frame is fixedly connected to the separation chamber, and a separation component is detachably mounted on the mounting frame. A mounting part is also provided on the periphery of the separation tank, and multiple sets of support legs are evenly arranged on the mounting part. A top cover is also provided on the separation tank, and the top cover is detachably connected to the separation tank. A mounting base is provided at the end of the top cover away from the separation tank, and a hybrid component is also provided in the mounting base.

[0007] The above technical solution further includes that the separation component includes a filtrate tank, the filtrate tank is disposed in the separation chamber, and a plurality of limiting parts are evenly arranged on the periphery of the filtrate tank. A plurality of limiting grooves are also provided on the mounting frame corresponding to the plurality of limiting parts, and the plurality of limiting parts are respectively disposed in the limiting grooves.

[0008] The above technical solution further includes that multiple sets of slurry permeation holes are evenly arranged on the periphery of the filtrate bucket; and a telescopic groove is provided on the top of the filtrate bucket, and a handle is telescopically provided in the telescopic groove.

[0009] The above technical solution further includes that the separation component also includes a filter bag, the top of the filtrate tank is also provided with an installation groove, the top of the filter bag is also provided with an assembly part corresponding to the installation groove, and the filter bag is detachably installed in the installation groove through the assembly part.

[0010] The above technical solution further includes that the hybrid component includes a hybrid motor, which is detachably disposed in the mounting base; the mounting base is also provided with an assembly slot, through which the main shaft of the hybrid motor passes and is disposed in the separation chamber.

[0011] The above technical solution further includes that the hybrid component also includes a stirring shaft, the stirring shaft passes through the separation chamber, and the top of the stirring shaft is also provided with a connecting part, the connecting part being detachably connected to the main shaft of the hybrid motor.

[0012] The above technical solution further includes that the bottom of the separation tank is provided with a slurry outlet, and a control valve is provided on the slurry outlet; a feeding port is provided on the top cover near the mounting base, and a flip cover is rotatably provided on the feeding port.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The separation tank and top cover are combined to form a relatively closed filtration environment, greatly reducing the contact area and time between the soy milk and the outside air during the filtration process. This effectively prevents impurities, microorganisms, and other contaminants from entering the soy milk when the production environment is unfavorable. The internal separation components consist of a filtrate tank and a filter bag. The filter bag is installed in the mounting slot of the filtrate tank via an assembly part. This double-layer filtration structure can finely filter impurities such as soy pulp from the soy milk, ensuring filtration effectiveness while further reducing hygiene risks caused by exposure, thereby ensuring the quality, safety, and hygiene standards of the tofu product.

[0015] 2. The hybrid motor is installed in the mounting bracket of the top cover, and its main shaft is detachably connected to the stirring shaft via a connecting part. The stirring shaft is located inside the separation chamber. During the filtration process, the hybrid motor drives the stirring shaft to rotate, stirring and mixing the soy milk in the separation chamber. On the one hand, the stirring action makes the soy milk more evenly distributed in the filter bag and filtrate bucket, accelerating the filtration process of the soy milk through the filter bag and the permeation holes, improving the overall filtration efficiency, reducing filtration time, and increasing the production capacity of tofu. On the other hand, stirring can prevent soy residue from accumulating and clogging the filter holes in the filter bag and filtrate bucket, maintaining the continuous and efficient filtration performance of the separation components, extending the service life of the filter bag and filtrate bucket, reducing production costs, and helping to ensure the stability and continuity of the soy milk filtration process in tofu production.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0024] Example

[0025] like Figures 1 to 5As shown, this utility model provides a filtration device for tofu production, including a separation tank 1, a separation chamber 101 inside the separation tank 1, a mounting frame 102 fixedly connected inside the separation chamber 101, a separation component detachably mounted on the mounting frame 102; a mounting part 103 is also provided on the periphery of the separation tank 1, and multiple sets of support legs 2 are evenly arranged on the mounting part 103; a top cover 3 is also provided on the separation tank 1, the top cover 3 is detachably connected to the separation tank 1, and a mounting seat 104 is provided at the end of the top cover 3 away from the separation tank 1, and a hybrid component is also provided inside the mounting seat 104. Multiple support legs 2 on the mounting section 103 allow the entire device to be placed stably on the operating site, providing a stable support foundation for the tofu production filtration process. This prevents the device from shaking or tilting due to instability, thus avoiding affecting the filtration operation and the filtration quality of the soy milk. The combination of the top cover of the separation tank 1 and 3 effectively reduces the contact between the soy milk and the external environment during filtration, reducing the possibility of external dust, microorganisms, and other contaminants entering, ensuring the hygienic quality of the soy milk, thereby improving the quality and safety of the tofu. The detachable connection method facilitates the cleaning, maintenance, and replacement of parts of the equipment. The mounting bracket 102 is used to fix the separation components, ensuring their stable position during the filtration process, which is conducive to stabilizing the filtration effect.

[0026] The mixing component agitates and mixes the soy milk within the separation chamber 101. During filtration, the agitation ensures the soy milk is evenly distributed within the separation component, preventing localized areas of excessively high soy milk concentration or impurity buildup that could affect filtration efficiency and effectiveness. The agitation promotes rapid and comprehensive filtration of the soy milk through the separation component, increasing filtration speed, reducing filtration time, improving overall tofu production efficiency, and ensuring the continuity and stability of tofu production.

[0027] like Figures 1 to 4 As shown, the bottom of the separating tank 1 is also provided with a soy milk outlet 701, and a control valve 702 is also provided on the soy milk outlet 701; a feeding port 703 is also provided on the top cover 3 near the mounting base 104, and a flip cover 704 is rotatably provided on the feeding port 703. The soy milk outlet 701 is located at the bottom of the separating tank 1 to facilitate the smooth discharge of filtered soy milk, while the control valve 702 can precisely adjust the flow rate and speed of the soy milk. During the tofu production process, the output of soy milk can be flexibly controlled according to actual needs to ensure the coordination and stability of the entire production process and avoid adverse effects on production caused by soy milk flowing out too fast or too slow.

[0028] A feeding port 703 is provided on the top cover 3, providing a direct channel for the soybean milk raw materials to enter the separation tank 1. This facilitates quick and easy operation and reduces spillage during the feeding process. The feeding port 703 is equipped with a rotatable flip-top cover 704. During non-feeding periods, the flip-top cover 704 can be tightly closed, effectively preventing external dust, impurities, and microorganisms from falling into the separation tank 1 and contaminating the soybean milk. This maintains the hygiene of the internal environment of the filtration device, ensures that the tofu production process meets hygiene standards, reduces the risk of product quality problems caused by contamination, and helps improve the quality and safety of tofu products.

[0029] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the separation assembly includes a filtrate tank 4, which is disposed in the separation chamber 101. The filtrate tank 4 is also uniformly provided with multiple sets of limiting parts 201 on its periphery. The mounting frame 102 is also provided with multiple sets of limiting grooves 202 corresponding to the multiple sets of limiting parts 201. The multiple sets of limiting parts 201 are respectively disposed in the limiting grooves 202. The separation assembly also includes a filter bag 5. The top of the filtrate tank 4 is also provided with a mounting groove 401. The top of the filter bag 5 is also provided with an assembly part 402 corresponding to the mounting groove 401. The filter bag 5 is detachably disposed in the mounting groove 401 through the assembly part 402. The filtrate tank 4 has multiple sets of perforation holes 301 evenly arranged around its periphery; the top of the filtrate tank 4 also has a telescopic groove 302, within which a handle 303 is retractably installed; the filtrate tank 4 achieves precise positioning and stable placement within the separation chamber 101 by cooperating with the limiting part 201 on its periphery and the limiting groove 202 on the mounting frame 102. This installation method prevents the filtrate tank 4 from shaking or shifting during filtration, ensuring the stability and reliability of the filtration operation. Simultaneously, when cleaning, maintenance, or replacement of the filtrate tank 4 is required, it can be easily removed from the mounting frame 102, improving the operability and maintenance efficiency of the equipment components.

[0030] The filter bag 5 and the filtrate tank 4 form a double-layer filtration structure. The filter bag 5 is installed in the mounting groove 401 on the top of the filtrate tank 4 via the assembly part 402, which facilitates the disassembly and replacement of the filter bag 5. During the filtration operation, the filter bag 5 can first perform preliminary filtration of the soy milk, intercepting larger particles of impurities, such as larger pieces of soy residue. The soy milk filtered by the filter bag 5 then flows into the filtrate tank 4. The permeable holes 301 on the periphery of the filtrate tank 4 not only ensure the passage of soy milk but also further refine the filtration of the soy milk, removing even smaller impurities. This improves the precision and effect of soy milk filtration, effectively enhancing the quality and taste of tofu, reducing tofu quality problems caused by impurity residue, and making the produced tofu more delicate and smooth, meeting consumers' demand for high-quality tofu.

[0031] The telescopic groove 302 and built-in retractable handle 303 on the top of the filter tank 4 greatly facilitate its use. When it is necessary to remove the filter tank 4 for cleaning, maintenance, or replacement of the filter bag 5, the operator only needs to pull the handle 303 out of the telescopic groove 302 to easily move the filter tank 4. During normal filtration, the handle 303 retracts into the telescopic groove 302, without interfering with the operation of other components or the filtration of soy milk, thus improving the practicality and ease of operation of the equipment.

[0032] like Figures 1 to 3 As shown, the hybrid assembly includes a hybrid motor 6, which is detachably mounted in the mounting base 104. The mounting base 104 also has an assembly groove 501 through which the main shaft of the hybrid motor 6 passes and is positioned within the separation chamber 101. The hybrid assembly also includes a stirring shaft 601, which passes through the separation chamber 101 and has a connecting part 602 at its top, which is detachably connected to the main shaft of the hybrid motor 6. The assembly groove 501 in the mounting base 104 provides a stable and precise channel for the main shaft of the hybrid motor 6 to enter the separation chamber 101, ensuring the coaxiality and stability of the main shaft and the stirring shaft 601 after connection. This allows power to be transmitted efficiently and smoothly from the motor to the stirring shaft 601, reducing power loss and deviation during transmission. Simultaneously, it ensures that the stirring shaft 601 operates at a stable speed and torque within the separation chamber 101, thereby achieving a uniform and stable stirring effect on the soy milk.

[0033] Furthermore, the detachable connection between the connecting part 602 and the hybrid motor 6 allows for more flexible adaptation between the stirring shaft 601 and the main shaft of the hybrid motor 6. Different specifications or types of stirring shafts 601 can be easily replaced according to different production needs, such as the concentration and output of soy milk, to achieve the best stirring effect, thus improving the equipment's adaptability and versatility to different production conditions. Moreover, this also facilitates the individual maintenance, repair, or replacement of the motor and stirring shaft 601. When a component malfunctions, there is no need for complex disassembly and reassembly of the entire hybrid assembly, reducing the difficulty and cost of equipment maintenance and improving the maintainability and service life of the equipment.

[0034] The combination of the hybrid motor 6 and the stirring shaft 601 effectively stirs the soy milk in the separation chamber 101. During the filtration process, the stirring keeps the soy milk in constant motion, preventing impurities such as soybean residue from accumulating locally in the filter bag 5 or the filtrate tank 4 and clogging the filter holes, thus ensuring continuous and efficient filtration. Simultaneously, this stirring accelerates the contact and separation process between the soy milk and the filter bag 5 in the separation component, increasing the filtration speed and shortening the filtration time, thereby improving the efficiency of the entire tofu production process.

[0035] The above description is merely an embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
